Diet composition stats typos?
Beth Mazur (2010-07-02 16:54) NA
Are the carb and protein percentages of the diets swapped? Abstract says that diet
composition stats are presented as (kcals; % carbohydrate: protein: fat). Yet the
very low carbohydrate, high protein diet (VLCHP) is presented as [1,200 kcals; 63:7:30
%]. And the low carbohydrate, moderate protein diet (LCMP)is presented as [1,200 kcals;
50:20:30 %].

Nutrition ratio/description mismatch or error
gamma sync (2010-07-02 16:55) Individual
The article describes the diets as:
high carbohydrate, high energy diet (HED) + exercise (2,600; 55:15:30%);
very low carbohydrate, high protein (VLCHP) + exercise (1,200; 63:7:30%),
low carbohydrate, moderate protein (LCMP) + exercise (1,200: 50:20:30%),
high carbohydrate, low protein (HCLP) + exercise group (1,200: 55:15:30%)
And further says the nn:nn:nn numbers are % carbohydrate: protein: fat
But, the descriptions do not match the ratios. The "Very Low carbohydrate" diet is 63% carbohydrate, which is the highest carb of all of the choices.
As this is the diet which has the most significant weight loss result, it is odd that the name and the proportions are in direct opposition.
None of the diets differ enough in proportion to justify the use of the modifier "very", with the exception of the very low protein content (7%) of the diet called "very low carbohydrate".
