Weight Watchers points Plus

Weight watchers have revised their point system and come with a completely new program-called points Plus (or dots Pro in the United Kingdom).
The formula of the previous points (begun in 1997) took into account calories, grams of fiber and grams of fat. The formula of PointsPlus uses protein, carbohydrate, fibre and grams of fat.
Weight watchers have spent a number of years of testing the new program (at the Medical University of South Carolina among other places). Basis Weight Watchers trials caused "an improvement in behaviors that help people maintain the weight loss and the desire to eat when there is no physical hunger or need to feed a reduction". (src).
Critics of the previous formula points stated that it did not accurately differentiate between most nutritionally dense foods and "empty calories". This is due to the heavy weighting of calories compared to measures of other nutrients.
When we have an Apple 100 calories in one hand and a package of 100 calories of cookies in nothing more, and we consider them as "the same" because the calories are the same, they say all that needs to be said about the limitations of using only the calories in leading food choices.

What is the new formula?
Points Plus = (grams of protein/10.9) + (grams of carbohydrates/9.2) + (grams of fat/3.9) + (grams of fibre/35).
So, for a Big Mac,

Points Plus = 25/10.9 + 45/9.2 + 29/3.9 + 3/35
Points Plus = 2.29 + 4.89 + 7.44 + 0.09

Points Plus = 14.71 (value of the preceding paragraph was 13.97).

Note that this formula is via Wikipedia (ProPoints), and we cannot guarantee that this is accurate, and that you must use tools WW officers for precise values Plus points. Is perhaps the U.S. formula is slightly different. Some have suggested the value should be CARB Gram (Carb-fiber)/9.2 account to label the differences between the United States and United Kingdom.


What else changed plus points

Foodstuffs of weight Watchers will point values (an indicator that perhaps foodstuffs brand aren't particularly nutrients?).
