Most Important Diet Factor: Carbohydrate or Calorie Restriction?

August 28th, 2007 by Paul Johnson

With the growing popularity of low carb dieting, one has to wonder if simply dropping carbs is really behind weight loss? Most bodybuilders and scientist believe it is common sense, that it all comes down to calories. If you simply eat more than you burn off you have to gain the weight. What does science on the issue say?

A study a few years ago by a group of researchers in Canada, compared groups of people on various calorie levels and carbohydrate ratios. The results found that calorie restriction was the most important factor in weight loss. No surprise there, something all of us bodybuilders knew all along. The research is based on "weight loss" however, but weight loss and fat loss are highly correlated anyways, so the study serves it's purpose.
