A Randomized Trial Comparing Low-Fat and Low-Carbohydrate Diets Matched for Energy and Protein
The preliminary results presented in this paper are for the first four of six postmenopausal overweight or obese participants who followed, in random order, both a VLC [very-low-carbohydrate] and an LF [low-fat] diet for 6 weeks. Other outcome measures were serum lipids, glucose, and insulin, as well as dietary compliance and side effects. Our results showed no significant weight loss, lipid, serum insulin, or glucose differences between the two diets. Lipids were dramatically reduced on both diets, with a trend for greater triglyceride reduction on the VLC diet. Glucose levels were also reduced on both diets, with a trend for insulin reduction on the VLC diet. Compliance was excellent with both diets, and side effects were mild
Essentially the study showed that the calories had an impact on weight loss but the makeup of those calories did not. Don’t forget this is just one study. Listen to interview with the Author, Frank Sacks, on Science Friday on NPR.
