Verdict of Science
 High-protein
diets which bans
carbohydrate is a danger to your
health and should be avoided
 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.
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.
