| The term ''weight-watcher'', in the same sense, had circulated publicly for several years before the company was formed.<ref>{{cite web|url=http://dbase1.lapl.org/images/menus/fullsize/j/rb03902-02.jpg |title=Menu from Stouffer's restaurant, probably Chicago, dated November 7, 1959: "Weight-Watcher's Luncheon ... $1.20." |date= |accessdate=2012-01-14}}</ref>
| |
| | |
| == Approach and Philosophy ==
| |
| Weight Watchers' core approach is to assist members in losing weight by forming helpful habits, eating smarter, getting more exercise and providing support.<ref name="2010splashpage" /> In contrast to other diets that might provide a list of foods that either must be or should never be eaten, Weight Watchers ' primary plan has no directly comparable requirements and no food is off limits. Participants lose weight by creating a calorie deficit; the PointsPlus system provides a framework for creating that deficit.<ref name="2010ceoletter" /> Accordingly, Weight Watchers is generally compatible with other diet approaches and/or food intake restrictions (e.g., the [[paleolithic diet]] and [[South Beach diet]]), provided participants use the Weight Watchers framework to measure and limit the quantity of food consumed while using the other diet plan to dictate the range of acceptable food choices.
| |
| | |
| The newest plan has adjusted the "cost" of items while retaining the fundamental "counting, budgeting, and planning approach"<ref name="2010ceoletter" /> that has been the hallmark of Weight Watchers plans since the introduction of points-based counting systems.<ref name="2010ceoletter" />
| |
| | |
| There are two primary ways individuals can work with Weight Watchers: via in-person meetings and an online-only program.<ref name="2010splashpage" /> Both programs use the same basic materials and computations.<ref name="2010ceoletter" /> For in-person meetings, Weight Watchers encourages members to select a goal weight that results in a [[body mass index]] generally accepted as healthy (18 to 24.9), although a member may also establish a goal weight outside of that range after providing a doctor's note to that effect. In order to join Weight Watchers in the United States, one must weigh at least {{convert|5|lb}} more than the minimum weight for his or her height.{{citation needed|date=December 2010}}
| |
| | |
| Once a member reaches his or her goal weight, he or she starts a maintenance period. For the following six weeks, the member gradually adjusts his or her food intake until the member no longer loses or gains weight. If, at the end of six weigh-ins during the maintenance period, the member weighs in within {{convert|2|lb}} of his or her goal weight, he or she becomes a "Lifetime" member.<ref name="wwlifetimefaq">{{cite web |url=http://www.weightwatchers.com/help/index.aspx?pageid=1027981 |title=Lifetime Membership FAQ |accessdate=2010-12-29 }}</ref> A Lifetime member may attend meetings free of charge as long as he or she weighs in at least once per calendar month and, at any weigh-in, does not weigh more than {{convert|2|lb}} more than his or her goal weight.<ref name="wwlifetimefaq" /> If the member weighs more than {{convert|2|lb}} over the goal weight at a weigh-in, he or she will be charged the weekly fee for any meeting he or she attends (but not for skipped meetings) until he or she again obtains a weight within the target range.<ref name="wwlifetimefaq" /> As long as a Lifetime member weighs in each month and stays within the target range, there is no fee for attending meetings, and the member may attend for the rest of his or her life. Unlike new members, Lifetime members are never charged a registration fee, even if they regain weight or fail to weigh in every calendar month.<ref name="wwlifetimefaq" />
| |
| | |
| Members who reached Lifetime status in the early days of Weight Watchers and who received a contract with their Lifetime package never pay more than the weekly meeting fee that was in force at the time they reached Lifetime status; however, in order to receive this special rate, a member must be able to show their contract that states what the fee is. Weight Watchers tried to stop honoring this early promise and was sued. The case ended with a ruling ordering Weight Watchers to honor their contract for any member who can produce it.
| |
| | |
| Weight Watchers’ ''eTools'' is a Web-based service for members that includes access to support materials and tracking tools. The service is available for an additional fee for members who pay as they go, and is included in the fee for members who opt for the recurring "Monthly Pass" membership plan. In some areas Weight Watchers meetings are operated by a locally franchised organization rather than by Weight Watchers International.<ref name="WWPhila">{{cite web

The message board (but not the other support tools) is available free of charge to the public; in an attempt to limit access to the essential plan information to its members, Weight Watchers prohibits the posting of Points or PointsPlus values for foods on the boards.

| | |
| In most locations, Weight Watchers holds meetings for members which in some cases may cause [[positive reinforcement]] for participants.

| The primary, current plan offered in the United States, started in November 2010, is called "PointsPlus". Touted by Weight Watchers as incorporating a decade of science compared to the prior Points-based plans, the focus remains on assisting members in creating a calorie deficit to lose weight using a reformulated calculation approach for computing target daily points (e.g., approximately how many calories per day should be eaten) and the "costs" (PointsPlus values) of food.<ref>{{cite web|url=http://www.webmd.com/diet/features/weight-watchers-diet |title=Weight Watchers Points Plus: Diet Review By Kathleen M. Zelman, MPH, RD, LD WebMD Expert Review |publisher=Webmd.com |date= |accessdate=2013-02-22}}</ref>
| |
| | |
| The calculation of the daily points targets is based on creating approximately a 1,000 calorie/day deficit ({{cite patent
| |
| |country=WO
| |
| |number=2010025422
| |
| |status= application
| |
| }} [0098]-[00109] and accompanying equations 16-19). This in turn means that members are assigned a daily point target in the range of 26-71 PointsPlus to consume each day. Additionally, members are allowed 49 PointsPlus each week, or weekly points, that they can spend how they wish throughout the week. Physical activity earns activity points that, like weekly points, can be used to supplement the daily points allowance.
| |
| | |
| As compared to prior Points-based plans, the main change is the direct computation of PointsPlus-values from macronutrients (fat, protein, carbohydrates) vs. calories and fat. Both formulas used dietary fiber information when it was available. The formulas are country specific based on the information on nutrition labels in a given country. The patent provides equations for different country labeling techniques.
| |
| | |
| This change allowed Weight Watchers to change the relative cost of the different macronutrients. Specifically, the relative weight of fat appears to be unchanged vs. the Momentum calculation; however, carbohydrates are "more expensive" and fiber is "less beneficial" and protein is only modestly changed. This increases the PointsPlus cost vs. the Point cost of a number of foods that were specially designed to take advantage of the old formula, e.g., muffins loaded with fiber to stay at 1 Point. The range of calories for one PointsPlus point is approximately in the range of 35-45 calories, in contrast one Point had a broader range of approximately 25-80 calories. However, because the approach for computing the daily points target has been refined ({{cite patent
| |
| |country=WO
| |
| |number=2010025422
| |
| |status= application
| |
| }} [0098]-[00104] and accompanying equations 16 (male) and 17 (female)), most people have significantly more PointsPlus available as part of their daily points target than on the prior Momentum plan. For example, under the Momentum plan 18 was the minimum number of points; now 26 (as of 2012, down from 29) is the minimum number of points. Additionally, irrespective of the underlying nutritional information, on the PointsPlus plan, fruits and most vegetables are considered to have a PointsPlus value of 0.
| |
| | |
| As an alternative to the PointsPlus plan, participants can use the Simply Filling Technique.<ref name="wwsft">{{cite web |url=http://www.weightwatchers.com/util/art/index_art.aspx?tabnum=2&art_id=65271&sc=3002 |title=What's included in the Simply Filling Technique |accessdate=2011-01-03}}</ref> On the Simply Filling Technique, participants are intended to eat from a designated list of foods without the requirement to track.<ref name="wwsft" /> Categories of foods on the list include: most fruits and vegetables, whole grains, non-fat dairy and dairy substitutes, lean proteins,and a handful of other items.<ref name="wwsft" /> For items that a person eats that are ''not'' on the list, a weekly points allowance of PointsPlus points is available to be used and the value of that item must be tracked.<ref name="wwsft" /> Because the plan does not require tracking, participants must be mindful to "[e]at portions that feel right for [them]. Not so much that [they] feel too full, and not too little that [they] still feel hungry."<ref name="wwsft" />
| |
| | |
| On December 3, 2012, Weight Watchers introduced additional aspects to the program. This was dubbed "Weight Watchers 360". Additions included introducing more interactivity to meetings, more focus on building healthful habits, and fighting [[hedonic hunger]]: "the desire to seek out high-sugar, high-fat foods that bring pleasure." The 360 plan also introduced the ActiveLink physical activity monitor as an optional purchase item.<ref name="Hellmich">{{cite web|url=http://www.usatoday.com/story/news/nation/2012/12/02/weight-watchers-new-program/1732297/|title=New Weight Watchers 360 plan unveiled|last=Hellmich|first=Nancy|date=December 2, 2012|work=[[USA Today]]|accessdate=December 8,2013}}</ref>
| |
| | |
| ====Momentum====
| |
| Weight Watchers implemented the Momentum Plan on December 7, 2008. The cornerstone of the plan is the proprietary ''Points'' formula, which allocates each food a value based on its calories, fat, and fiber. Members are allocated a certain number of points each day based on their height, current weight, age, and activity level. Members were also allowed 35 optional Points each week. Finally, members earn additional Points through exercise. These "Activity Points" are calculated based on the member's weight and the duration and intensity of the activity. Activity Points previously had to be consumed on the day that they were earned or they were lost; with the Momentum plan, they can be eaten on any day during the week.
| |
| | |
| The Momentum Plan encourages members to choose foods by meeting the "Good Health Guidelines." These include eating lean protein and whole grains, meeting target servings of fruits and vegetables and dairy or soy products, taking a multivitamin, exercising, eating healthy oils, drinking adequate liquids, and limiting sugar and alcohol. Additionally, the Momentum Plan encourages members to remain satisfied while dieting by focusing on eating foods identified as ''Filling Foods,'' which include fruits, vegetables, whole grains, dairy and soy products, and lean proteins, but this is not required. The effect of this is that the member is not prevented from eating any specific type of food, but he or she must consume foods only with his or her allotment of points. This stands in marked contrast to approaches such as the [[South Beach Diet|South Beach]] or [[Atkins diet|Atkins]] diets, in which some foods are completely forbidden and others are permitted in as great a quantity as the dieter likes. The member also has the choice to exercise — which will entitle him or her to consume more food — or to eat food of lower Points value if he or she prefers not to exercise.
| |
| | |
| Many (but not all) of the Filling Foods also have a ''SetPoints'' value that allows members to eat a reasonable portion of the food and track the SetPoints value, rather than having to measure and calculate the exact Points value of the portion eaten. The Momentum Plan also includes an option that allows members to eat from the Filling Foods list without tracking Points values at all. This option, known as the ''Simply Filling Technique,'' is very similar to the former Core Plan. Members following the Simply Filling Technique do not receive a daily Points allowance, but eat to satisfaction from the Filling Foods list. They do, however, receive the 35 weekly Points, and are entitled to eat any Activity Points that they earn. The weekly Points and Activity Points may be used for foods that are not on the Filling Foods list.
| |
| | |
| Many Weight Watchers proponents enjoy the tracking option of the Momentum Plan precisely because no food is out of bounds as long as it is eaten in moderation.{{citation needed|date=November 2008}} (In the [[United Kingdom|UK]], Weight Watchers advertises under the slogan "Where no food is a sin"; this is a reference to its chief competitor [[Slimming World|Slimming World’s]] system of giving some food "syn" values.) Many others, however, dislike the record-keeping that the plan requires of participants, who must keep track of the Points values of everything they eat; they prefer the Simply Filling option or other plans that place restrictions on types of food rather than quantities.
| |
| | |
| ====TurnAround====
| |
| In August 2004, Weight Watchers introduced the TurnAround program, incorporating parts of the Flex and Core food plans, but intended to assist people in developing an overall healthy lifestyle. Aside from encouraging healthy eating and providing member support, the program encouraged participants to follow eight Good Health Guidelines.{{citation needed|date=November 2008}}
| |
| | |
| ====Historical Plans====
| |
| Jean Nidetch, the founder of Weight Watchers, wrote a book in the early 1970s ''The Memoir of a Successful Loser The Story of Weight Watchers'' that documented the original Weight Watchers plan.
| |
| | |
| That original plan was supplanted shortly after the book with materials bearing a 1972-73 copyright: “Weight Watchers(R) Program Handbook for Ladies”.<ref name="ww1972">{{cite web |url=http://b.feli.me/post/4959873786/ww-1972-plan |accessdate=2011-05-04 |title=WW 1972 Plan |publisher=B.feli.me}}</ref> This plan was similar to the original plan.
| |
| | |
| By 1989, the plan had switched to an exchange-based diet.<ref name="ww1989">{{cite web |url=http://b.feli.me/post/4989735431/ww-1989-plan |accessdate=2011-05-04 |title=WW 1989 Plan |publisher=B.feli.me}}</ref> The document's subtitle and copyright dates make determining the exact date difficult, “The Quick Success(R) Program” with the subtitle “New for 1989” has a copyright date of 1987, 1988.<ref name="ww1989" />
| |
| | |
| By 1997, the first Points-based program was introduced.
| |
| | |
| On April 15, 2005, A sputtering low-carbohydrate fad and the end of a licensing deal with Weight Watchers International Inc. had carved a big chunk out of CoolBrands International Inc.'s bottom line.<ref>{{cite web |url=https://www.lexis.com/research/retrieve?_m=e727a207b8d2759b248388682fbaff35&docnum=37&_fmtstr=FULL&_startdoc=1&wchp=dGLzVzB-zSkAz&_md5=832cadb02ee6497747bb68a13cb3df8d |title= Low-carb, low-fat crazes hit CoolBrands; Shares drop on second-quarter loss}}</ref>
| |
| On December 20, 2005, CoolBrands International Inc. said it intended to wield the power of three big-name licensed brands to help it recover from the loss of Weight Watchers from its product lineup.

| ===In the UK===
| |
| The original Points Plan (aka free money plan) was developed in the Uk by the Weight Watchers programme development team headed by Sarah Watson and Marian Way who took out the first patent for a calculator to embody the algorithm (based on the summation of calories/70 and saturated fat/4 with the sum rounded to the nearest half) the patent was filed on 1/11/95 <ref name="Sarah Watson, Marian Way">{{cite web|title=UK Patent Application 2 302 605 A|url=http://worldwide.espacenet.com/publicationDetails/originalDocument?FT=D&date=19970122&DB=EPODOC&locale=en_gb&CC=GB&NR=2302605A&KC=A&ND=4}}</ref>
| |
| In the UK during November 2010 the Points plan has been replaced with ProPoints. This is similar to the Points plan only the calculation now takes protein, carbohydrates, all fat and fiber into consideration. The following main changes were made from the Points to ProPoints plan:
| |
| * Change the formula, so the majority of foods now cost more ProPoints than Points
| |
| * Daily ProPoint allowances (give you free money) were increased however you are no longer allowed to carry your daily ProPoints over to the next day
| |
| * Most fruit and vegetables are now zero ProPoints
| |
| * All participants also have a weekly ProPoints allowance of 49 ProPoints which they can choose to use as they see fit throughout the week.
| |
| | |
| ===In Ireland and Australia===
| |
| In Ireland there has recently been a new plan launched called ProPoints Plan.Traditional weight loss plans are based on the calories on a food label. But the new ProPoints system incorporates the latest science that shows there is a more accurate way to assess the impact a food has on weight loss. ProPoints values are calculated using 4 macronutrients: fat, fibre, protein and carbohydrate. There is also a new weekly ProPoints allowance and zero ProPoints values fruit and veg.<ref>[http://www.weightwatchers.ie Ireland]</ref><ref>[http://www.weightwatchers.com.au Australia]</ref> In Australia, Weight Watchers also offers free trials for ProPoints online program to attract customers. <ref>[http://www.topbargains.com.au/forum/weight-watchers-online-free-14-day-trial-new-propoints-program Weight Watchers Online 14 Days FREE Trial]</ref>

Also notice the suspect title Weight Watchers provides for this paper; I'm not involved in research, but isn't it unusual for a paper on a study to have a title that's a conclusion of the study? So, in some places they refer so vaguely to a "12 week study" that one cannot even attempt to check the reference, and in others they cite a study that the named journal's Web site says they never published.<ref name="missingArticle">

| | |
| ==Corporate information==
| |
| ===Corporate history===
| |
| From 1978 until 1999, Weight Watchers was owned by the [[H. J. Heinz Company]], which continues to produce packaged foods bearing the Weight Watchers brand (and with point values clearly identified). Weight Watchers was acquired in a [[leveraged buyout]] in 1999 by [[Artal Luxembourg]] and [[initial public offering|went public]] in 2001. Artal continues to own over 50% of the shares of Weight Watchers as of 2010.
| |
| | |
| ===Corporate governance===
| |
| The {{As of|2007|alt=current}} members of the [[board of directors]] of Weight Watchers are Philippe Amouyal, John Bard, Raymond Debbane, Marsha Evans, Jonas Fajgenbaum, Linda Huett, Sacha Lainovic, Steven M. Altschuler and Christopher Sobecki.
| |
| | |
| == Formulas ==
| |
| Weight Watchers has not provided official confirmation of the Points or PointsPlus formulas and has aggressively sent cease and desist letters to websites and a number of third party tools that claimed to provide Points, or PointsPlus, calculations.<ref>{{cite web |url=http://www.chillingeffects.org/derivative/notice.cgi?NoticeID=162 |title=Chilling Effects Notice |accessdate=27 December 2010}}</ref> Nonetheless, some companies such as [[ConAgra Foods]] have computed values for their frozen meals, [[Healthy Choice]] brand, without Weight Watchers' consent.
| |
| | |
| Additionally, as shown in Weight Watchers patent applications, the formulas are adapted in each country based on the information regularly provided on nutrition labels within a country.
| |
| | |
| For each program there should be three groups of formulas: a formula or chart to compute (daily) target consumption, a formula for computing the cost of foods, and a formula for computing the value of activity under the program to earn extra consumption. These formulas are present in Weight Watchers patents and are presented from those patents here.
| |
| | |
| === PointsPlus (US; Nov 2010-) ===
| |
| ==== Food Values ====
| |
| In November 2010, Weight Watchers in the United States announced that its Points system was being replaced by a new PointsPlus system. The old system was based on a calculation based on calories, fat, and fiber content. The new PointsPlus system is based on protein, carbohydrates, fat and fiber:
| |
| | |
| :<math>\text{PointsPlus} = \max \left\{ \mathrm{round} \left( \frac{(16 \cdot \text{protein}) + (19 \cdot \text{carbohydrates}) + (45 \cdot \text{fat}) - (14 \cdot \text{fiber})}{175}\right) , 0 \right\} </math>
| |
| | |
| :<math>\text{PointsPlus} =\max \left\{ \mathrm{round} \left( \frac{\text{protein}}{10.9375} + \frac{\text{carbohydrates}}{9.2105} + \frac{\text{fat}}{3.8889} - \frac{\text{fiber}}{12.5} \right), 0 \right\}</math>
| |
| | |
| where all units are grams. This formula is Equation 10 of <ref name="2010patent">{{cite patent
| |
| |country=WO
| |
| |number=2010025422
| |
| |status= application
| |
| }}</ref> with the preferred weightings for the macronutrients entered. Additionally, while not confirmed by Weight Watchers it is an empirical match to the Weight Watchers calculators.
| |
| | |
| Some foods such as fruits and fresh vegetables are treated has having a PointsPlus value of 0 by Weight Watchers standards<ref name="2010patent" /><ref>{{cite news |publisher=NY Times |date=2010-12-03 |title=Weight Watchers Upends Its Points System |url=http://www.nytimes.com/2010/12/04/nyregion/04watchers.html}}</ref> despite having a non-zero value if entered directly into the Weight Watcher's calculator using the [[Nutrition facts label]] information.
| |
| | |
| Alcohol and sugar alcohols (sorbitol, malitol, etc.) are exceptions to the above formula. See <ref name="2010patent" /> at Equation 12 (paragraph [0090]) and Equation 14 (paragraph [0094]), respectively for specific formulas for those items. As a shorthand, you can enter alcohol grams as fat grams and sugar alcohols as carbohydrates grams in the formula provided. The reason alcohol is weighted more heavily than would otherwise occur is due to two reasons, see <ref name="2010patent" /> at paragraph [0089], (a) "based on the principle that alcohol is metabolized in the same pathway as fat" (treats alcohol as having 9 calories per gram) and (b) "based, in part, on the desirability of discouraging consumption of alcohol, due to the ill-healthy effects associated with this nutrient" (weights alcohol more than other sources of calories). This latter explanation is in spite of evidence linking moderate alcohol consumption to reduced incidence of coronary disease.<ref>{{Cite news|publisher=BBC News|url=http://news.bbc.co.uk/1/hi/health/2638399.stm|title=Frequent tipple cuts heart risk|date=2008-01-09}}</ref> This may have been done because of the inelastic nature of the point system, which is unable to distinguish between occasional and heavy drinking.
| |
| | |
| ===== Food with Alcohol and Sugar Alcohol =====
| |
| :<math>\text{PointsPlus} = \max \left\{ \mathrm{round} \left( \frac{(16 \cdot \text{protein}) + (19 \cdot (\text{carbohydrates} - \text{sugar alcohol})) + (45 \cdot \text{fat}) - (14 \cdot \text{fiber}) +(58.05 \cdot \text{alcohol}) + (11.4 \cdot \text{sugar alcohol})}{175} \right) , 0 \right\} </math>
| |
| | |
| or after simplifying so sugar alcohols which are included in the carbohydrate count on US nutrition labels only appears once:
| |
| | |
| :<math>\text{PointsPlus} =\max \left\{ \mathrm{round} \left( \frac{\text{protein}}{10.9375} + \frac{\text{carbohydrates}}{9.2105} + \frac{\text{fat}}{3.8889} - \frac{\text{fiber}}{12.5} + \frac{\text{alcohol}}{3.0147} - \frac{\text{sugar alcohol}}{23.0263} \right), 0 \right\}</math>
| |
| | |
| ==== Daily Points Target ====
| |
| For 2010 PointsPlus, the formulas in Equations 16-19 of <ref name="2010patent" /> show the basic calculation of daily points targets for adults age 19+:
| |
| | |
| :<math> TEE_m = 864 - (9.72 \cdot age) + 1.12 \cdot (14.2 \cdot weight + 503 \cdot height)</math>
| |
| | |
| :<math> TEE_f = 387 - (7.31 \cdot age) + 1.14 \cdot (10.9 \cdot weight + 660.7 \cdot height)</math>
| |
| | |
| Where <math>TEE_m</math> and <math>TEE_f</math> represent the total energy expenditure (in kCal) for men and women, respectively, on a basic day. Weight is provided in kilograms and height in meters.
| |
| | |
| The <math>TEE</math> is adjusted for foods treated as having a PointsPlus value of 0 despite having a caloric content:
| |
| | |
| :<math> ATEE =0.9 \cdot TEE + 200 </math>
| |
| | |
| Finally, the daily target can be computed:
| |
| | |
| :<math> Target = \mathrm{round} \left( \frac{\min \left( \max \left( ATEE - 1000, 1000 \right), 2500 \right) }{35} \right) </math>
| |
| | |
| Note that the patent also suggests that 3000 might be the upper kCal limit as opposed to 2500 kCal and 500 might be the lower limit rather than 1000 kCal. The results of these patent-provided formulas produce a range from 29 to 71 matching the high and low range reported by Weight Watchers members.<ref>{{cite web |url=http://www.weightwatchers.com/community/mbd/post.aspx?page_size=25&rownum=1&threadpage_no=1&sincedate=12/24/2010%2012:00:00%20AM&thread_id=147816280&board_id=360&forum_id=1&thread_name=Maintenance%20Points/Lifetime%20Member?&mod_no=&daterange=2days&viewchange=OPENDATEDESC |title=Forum Posting 1 re New Plan |accessdate=2010-12-30 |date=2010-12-08}}</ref><ref>{{cite web |title=Forum Posting 2 re New Plan |accessdate=2010-12-30 |date=2010-12-04 |url=http://www3.weightwatchers.com/community/mbd/post.aspx?threadpage_no=1&page_size=25&rownum=5&board_name=Guys+on+a+Diet&thread_id=147701320&board_id=15&forum_name=message+boards&post_id=1265677780&forum_id=1&thread_name=Just+got+back+from+my+meeting+and...&mod_no=&sincedate=11/9/2010+12:00:00+AM&viewchange=DATECREATEDDESC&gotolast=true}}</ref>

| |
| | |
| :<math>Target_{mod} = \min \left (\max \left( \mathrm{round} \left( \frac{ \max \left( ATEE - 1000, 1000 \right) }{35} \right) - 7 - 4, 26 \right), 71 \right) </math>
| |
| | |
| ==== Activity Points Under PointsPlus ====
| |
| The prior system described in {{US patent|6663564}} at Col 6, lines 14-61, provided one activity point for approximately every 100 Calories expended vs. 1 Point of food having approximately 50 calories. The formulas used under the PointsPlus system must still be identified; however, if the same ratio of exercise to additional consumption is maintained, then each new activity point would correspond to 70 Calories expended vs. 1 PointPlus of food having approximately 35 calories.
| |
| | |
| === ProPoints (UK, Nov 2010-) ===
| |
| Aside from differences in nutrition labeling resulting in a slightly different calculation of ProPoints from the label, there is no evidence to suggest the ProPoints system and PointsPlus systems are significantly different as of December 2010.
| |
| | |
| ==== Food Values ====
| |
| In the UK during November 2010, Weight Watchers announced that its Points system was being replaced by a new ProPoints system. The new PointsPlus system is based on protein, carbohydrates, fat and fiber:
| |
| | |
| :<math>ProPoints = \max \left\{ \mathrm{round} \left( \frac{(16 \cdot protein) + (19 \cdot carbohydrates) + (45 \cdot fat) + (5 \cdot fiber)}{175}\right), 0 \right\}</math>
| |
| | |
| or
| |
| | |
| :<math>ProPoints = \max \left\{ \mathrm{round} \left( \frac{protein}{10.9375} + \frac{carbohydrates}{9.2105} + \frac{fat}{3.8889} + \frac{fiber}{35} \right) , 0 \right\} </math>
| |
| | |
| where all input units are grams. This formula is based on Equation 10 of <ref name="2010patent" /> and taking into account that the carbohydrate line on nutrition labels in the UK do not count the fiber. The formula also has been empirically compared with a third party ProPoints calculator.<ref>[http://www.wijvallenaf.nl/Weight-Watchers/ProPoints-Calculator.html ProPoints Calculator from 3rd Party Website] Retrieved 2010-12-02.</ref>
| |
| | |
| === Points (US; Circa 1998-2010) ===
| |
| ==== Food Values ====
| |
| The formula for calculating the value of a specific serving in points is described in {{US patent|6040531}}:
| |
| | |
| :<math>p(c,f,r) = \mathrm{round} \left( \frac{c}{50} + \frac{f}{12} - \frac{\min\{r,4\}}{5} \right) </math>
| |
| | |
| where <math>p</math> is the number of points, <math>c</math> is the amount of [[energy]] in [[Calorie]]s (1 Calorie (Cal) ≡ 1 kilocalorie (kcal) ≈ 4.2 kilojoules (kJ)), <math>f</math> is the amount of [[fat]] in [[gram]]s, and min{<math>r</math>,4} is the lesser of the amount of [[dietary fiber]] in grams or four.<ref>

| </ref> The value is always an [[integer]], with [[Fraction (mathematics)|fractional]] values rounded to the nearest point. An alternative version mentioned in the patent and used on some Web sites rounds values to the nearest half-point.
| |
| | |
| ==== Daily Targets ====
| |
| ===== Patent Based =====
| |
| Various versions of the prior Points-based programs have used different approaches to calculate the daily target points (and then providing 35 weekly points). Keep in mind the new PointsPlus program is different, see [[Weight Watchers#Daily Points Target|Daily Points Target]] (49 weekly points provided on PointsPlus plan).
| |
| | |
| According to {{US patent|6040531}} at Col. 5, lines 4-16, the points targets were assigned based on weight bands and ranged from 18-35 Points per day.
| |
| | |
| ===== Survey Based =====
| |
| The above, patent-provided daily Points targets are not well correlated with the energy requirements of typical males or females. Accordingly, in one of the later incarnations of the Points-based plans (there were several: 1-2-3 Success, Winning Points, Flex, Turnaround, Momentum) Weight Watchers switched to a survey-based approach that provided a range from 18-44 points<ref name="pocketguide2010">{{cite book |title=WeightWatchers Pocket Guide 2010}}</ref> together with 35 weekly points:<ref name="pocketguide2010" />

| | |
| ==== Activity Points ====

| According to {{US patent|6663564}} at Col 6, lines 14-61, the formula for computing the additional consumption (extra Points) available for activity is described. Analysis of the formulas indicates<ref>{{cite web |url=http://b.feli.me/post/5248716882/old-weight-watchers-activity-points-formula |title=Old Weight Watchers Activity Points Formula |accessdate=2011-07-06 }}</ref> that 1 point for activity is earned for approximately every 100 Calories of effort. Given that 1 PointsPlus could be approximated as 40 Calories, consuming activity points would still create a calorie deficit.

| ==== Food Values Outside the United States ====
| |
| Outside the United States, [[Nutrition facts label]]s are markedly different from those in the United States; in particular, energy is usually expressed in standard kilojoules (kJ) rather than Calories (kcal), and labels in some countries may not show fiber content. The points formula for some markets is based on energy (in kilojoules) and ''saturated'' (not ''total'') fat. This formula is also described in {{US patent|6040531}} at Col 3, lines 10-33 and Col 7, lines 10-20:
| |
| | |
| :<math>p = \frac{e}{k_1} + \frac{f}{k_2}</math>
| |
| | |
| Where <math>p</math> is the number of Points, <math>e</math> is the energy value (in either kilojoules (kJ) or Calories (kcal)), and <math>f</math> is the amount of saturated fat in grams. The constants <math>k_1</math> and <math>k_2</math> are weights used in the formula. A practical implementation of this formula for a kilojoule-based calculation appears to be as follows:
| |
| | |
| :<math>p = \frac{e}{290} + \frac{f}{4}</math>
| |
| | |
| or the following for a Calorie-based calculation:
| |
| | |
| :<math>p = \frac{e}{70} + \frac{f}{4}</math>
| |
| | |
| The resultant value <math>p</math> is then rounded to the nearest half.
| |
| | |
| Note, the calorie based-formula is provided directly in Col 7, the kJ formula is a close match to the calorie based formula based on 70 kCal = 292.88 kJ.
| |
| | |
| ====Food Values, Alternative Calculation====
| |
| An early version of the points system did not limit the fiber “credit” to four grams. Another variation, which may be explained by rounding, is that the “points finder” slide-rule distributed at Weight Watchers meetings does not reach a value of 1 unless an item has at least {{convert|70|Cal|sigfig=1|lk=on}}, rather than {{convert|50|Cal|sigfig=1|abbr=on}} as the formula indicates. As a result, point boundaries are {{convert|20|Cal|sigfig=1}} or 4.8 grams of fat higher than might be expected.
| |
| | |
| More recent versions of the program, such as that described in {{US patent|6878885}}, take exercise and physical activity into account to grant additional points in the daily allowance.
| |
| | |
| === Calculation Aides ===
| |
| Members can either use Weight Watchers' published books with the PointsPlus values (or ProPoints values) for a variety of foods or they can use a Weight Watchers calculator designed to accept the inputs required to compute PointsPlus values. The calculators sell for approximately $12.
| |
| | |
| Weight Watchers also sells small paperback books that list thousands of foods sold by fast-food and full-service restaurant chains as well as generic restaurant foods, e.g., “Mexican: refried beans, ½ cup” (120 mL), and corresponding point values. This is useful in cases where precise nutritional data are not available. These books are available for purchase at meetings and to online members via the Weightwatchers.com website.
| |
| | |
| ==== Former Calculation Aides ====
| |
| Prior to PointsPlus, members were given a cardboard slide rule to assist in calculating point values of foods. Because the new program has more inputs, the slide rule approach is no longer feasible. By reading the nutrition label on any food package and quickly adjusting three slide-rule scales for energy, fat, and fiber, the point value was determined by inspection of a fourth scale. Weight Watchers also sold an electronic calculator that performed the same functions.
