How Important is Diet in Fat Loss?

August 25th, 2007 by Paul Johnson

We always hear bodybuilders and fitness gurus tout how diet is the most important factor in fat loss. What does science say?

A study was done in 2002 at Harvard University on 36 rats to measure their fatty acid profiles. There was a control, low intensity excercise, and high intensity excercise. Each rat was then put into high carb diet or high fat diet. The study showed macronutrient changes were more important than the excercise differences.

While the study was done for fat loss, one could conclude logically that during bulking phases, macronutrient profiles in the diet would probably have a major impact on muscle gains.

    I’ve always said diet is everything. Good to see the science. Great post.
