 : WTW, founded in the 1960s by Jean Nidetch, is a company offering various dieting products and services to assist weight loss and maintenance. It started as a discussion group for how to best lose weight. It now operates in about 30 countries around the world, generally under the name "Weight Watchers" translated into the local language. Weight Watchers current spokesperson is Jenny McCarthy.
Perhaps its most prominent celebrity endorser is Sarah, Duchess of York. Before her, Lynn Redgrave appeared in a series of popular television advertisements for the packaged low calorie food division of the H.J. Heinz Company, then the parent of Weight Watchers.
In some areas, including the Philadelphia metropolitan area in the United States, Weight Watchers meetings are operated by a locally-franchised organization rather than by Weight Watchers International.[1]
Weight Watchers usually has a 'minimum weight' level, to protect those who are not actually overweight.
If those interested in Weight Watchers are above this 'minimum weight' then they can set up their weight loss goal with their local Weight Watchers leader. Height, age, and beginning weight are recorded in order to establish their goal weight.
Varying on location, Weight Watchers generally offers two distinct programs:
* The Flex program
* The Core program
The programs are supplemented by optional support groups which meet regularly and provide assistance to those trying to meet weight-loss goals.
Flex program
The Flex system is, in essence, a simple way to quantify a
participant's calorie intake and energy expenditure. Various servings
of food are assigned a specific number of points, and various types of
exercise are assigned negative numbers of points; a program participant
is allocated a certain number of points per day, with that number based
on the individual's current weight and weight goals.
The effect of this is that the participant is not restricted from
eating any specific type of food, but they must stay under their total
point value for the week.
This stands in marked contrast to diet
approaches such as the South Beach diet or the Atkins diet, under which
some foods are completely forbidden and others are permitted in
theoretically unlimited amounts. The participant's ability to factor
exercise into the plan increases its flexibility: the participant can
eat more points as long as they offset them with exercise, or eat fewer
points if they prefer not to exercise. By not restricting certain foods
the Flex Plan allows for your favorites by just giving each food item a
point value.
Many Weight Watchers proponents enjoy the Flex system precisely because
no food is out of bounds, as long as it is eaten in moderation, and
because exercise can be factored in. (In the UK, Weight Watchers
advertises under the slogan "Where no food is a sin"; this is a
reference to its chief competitor Slimming World's system of giving
some food "sin" values.)
Others, however, dislike the record-keeping
that the plan imposes on the participant, who must essentially keep
track of the points value of everything they eat; they prefer other
plans that place restrictions on types of food rather than amounts of
food.
[edit] The POINTS formula
The formula for calculating the POINTS content of a specific food
serving uses a formula described in U.S. Patent 6,040,531 : p(c,f,r) =
\frac{c}{50} + \frac{f}{12} - \frac{\min\{r,4\}}{5}
Where p is the number of points, c is the number of calories, f is the
grams of fat, and r is the grams of dietary fiber (if the dietary fiber
is greater than four, use four). The POINTS value is always an integer,
with fractional values rounded to the nearest point. (An alternative
format, mentioned in the patent and used on some websites, rounds
values to the nearest half-point.)
New members are given a cardboard slide rule to assist in calculating
point values: by reading the nutrition label on any food package and
quickly adjusting three of the slide rule scales for Calories, Fat, and
Fiber, the points are easily determined by inspection of the fourth
scale. In addition, a simple calculator is available that allows a
member to quickly enter the Calories, Fat, and Fiber and immediately
see the resultant POINTS.
A small paperback book is available for purchase that lists thousands
of foods for sale in Fast Food outlets, restaurant chains, and even
generic restaurant foods, e.g. "Mexican: Refried Beans, 1/2 cup" and
the corresponding point value. This is for use in cases where the
nutritional label is not available.
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 "POINTSfinder" manual calculator distributed at Weight
Watchers meetings does not reach a POINTS value of 2 until after 70
calories have been reached, rather than 50 as the formula would
indicate. As a result, point boundaries are 20 calories (or 4.8 fat
grams) higher than might be expected. Though the patent mentions
possibly using 70 rather than 50 as the single point baseline, that
method is said to be intended for use by dieters who do not use fiber
as a "point enhancer" (reducer).
More recent versions of the program, such as that described in US
Patent 6,878,885, take exercise and physical activity into account to
grant additional points in the daily allowance.
In Europe and some other areas or countries, including Australia and
New Zealand, the nutrition labels are markedly different; in particular
they normally show kilojoules rather than calories, and may not include
fibre. Thus, the POINTS formula varies and it calculated only from
energy (as kilojoules) and saturated fat. This formula is expressed in
UK Patent 2302605 as: p = \frac{e}{k1} + \frac{f}{k2}
Where p is the number of points, e is the energy value, and f is the
grams of saturated fat. The constants are k1 and k2 are described as
such: k1 is chosen so that the points target will be in the low tens.
If the energy value is to be entered in calories, then k2 will be
within the range of k1/35 and k1/10, ideally k1/17.5. If the energy
value is defined in kilojoules, then the value of k2 will be between
k1/146.7 and k1/41.8, ideally being k1/72.8.
A practical implementation of this formula for a kilojoule-based
calculation appears to be: p = \frac{e}{300} + \frac{f}{4.12}
or p = \frac{e}{72} + \frac{f}{4.12}, for a calorie-based calculation.
The resultant value, p is then rounded to the nearest half.
The Core Plan
In part as a response to the popularity of plans like Atkins and South
Beach, Weight Watchers has recently developed a separate plan, known as
the Core Plan. This plan classifies certain types of food as "core,"
and permits participants to eat core foods with the restriction that
they should only eat these foods "until satisfied, not full." Core
foods are a list of healthy foods from all the food groups, including
fruits, vegetables, fat free dairy, lean meats, and whole grains.
Non-core foods are assigned the usual point values, and participants
are given an allottment of 35 non-core points that they can eat in a
week.
[edit] The Flex Plan
Under this plan, participants are assigned a set number of points to
consume per day based on their current weight. The number of points
allowed may be increased with exercise. As in the Core Plan,
participants are given an allotment of 35 "flex" points, above and
beyond the per-day points, that can be eaten in a week.
TurnAround
In August of 2004 the TurnAround Program (a registered trademark) was
introduced which not only incorporated the Points and Core food plans
but is intended to assist people with developing an overall healthy
lifestyle. The program includes healthy food intake but also includes
following 8 Good Health Guidelines, activity and member support. It is
through all of the aspects of the program that members are able to not
only reach their weight loss goals but to make permanent changes to
support lifetime weight management.
In England, the plans are referred to collectively as the "Switch"
program, and the two plans are called "The Points Plan" and "The Core
Plan." They essentially correspond to the Flex and Core in America,
except that in England there is no such thing as the 35 "flex" points
allotted per week in the "Flex" plan, and the Core Plan UK members get
only 21 points per week outside of their Core diet. In "The Points
Plan," one may eat less points than has been calculated from their sex,
weight, age, height, pregnancy status, and activity level and save
these points up for a special occassion within the week. Interestingly,
members in England know nothing of the American system while they could
easiily follow it. Dietary fiber is listed on almost every food item
and allows an American member the ability to eat foods that are high in
fiber and are filling, while using fewer points than they do on the UK
system.
Price
Like many other weight loss programs, Weight Watchers frequently offers
promotions and coupons ranging from free registration (normally thirty
dollars) to advance-purchase plans that bring the weekly cost down from
twelve dollars on average to less than nine. Of all of the weight-loss
plans currently popular throughout the United States, Weight Watchers
is one of the most reasonably priced as long as a member attends each
week--missed meetings must be paid in full before the next weigh-in,
which is a surprise to some members.
Once a member reaches their goal weight and maintains that weight
within plus
or minus two pounds for six weeks they become Lifetime Weight Watchers
members.
They can then attend any number of meetings anywhere for free,
as long as they weigh no more than 2 pounds above their goal weight and
weigh in at least once per month. Part of the success of Weight
Watchers members keeping weight off is the continued free support of
their weekly meetings.
Weight Watchers Online is another option for dieters, where for a
monthly fee they have access to all support materials and programs
through E-Tools. This alternative is for people who don't want to
attend meetings, and is a more independent approach to weight loss. The
support system for WW Online is a message board, where dieters can post
support and share advice. Although using WW Online has been proven
successful for many Weight Watchers members, research has shown the
members lose three times more weight by attending regular meetings.

The Flex system is, in essence, a simple way to quantify a participant's calorie intake and energy expenditure. Various servings of food are assigned a specific number of points, and various types of exercise are assigned negative numbers of points; a program participant is allocated a certain number of points per day, with that number based on the individual's current weight and weight goals.
