verdict of science
Verdict of Science

  • Diets that go for a single specific nutrients or food components to avoid are not advisable

Verdict of Science

George Bray, MD - Low-CHO Diets and Weight Loss

Weight loss was predicted by total calorie intake, diet duration but not by CHO content alone.

efficacy and safety of low cal diets a systematic review by bravata sanders huang et al
Efficacy and safety of Low-Cal Diets – A Systematic Review By Bravata, Sanders, Huang et. al.

Diets that restricted calorie intake, used longer in duration were associated with weight loss rather than CHO intake.

Scientific Review of Popular Diets By Freedman, King and Kennedy

Weight Loss

Short term high-fat, low-CHO causes a great loss of body water rather than body fat when these diet ends water weight is regained.

All reduced calorie diets results in body fat loss if sustained long term.
