For as long as I can remember there have been people crusading for each diet approach as being better than the other. I personally have been able to lose weight following both types of diets and have been in the camp that it really does not matter which type of diet you use, as long as you are in a calorie deficit.
A major new randomized clinical trial (RCT) on low-fat vs. low-carb diet by Christopher D Gardner, PhD, from Stanford University, California, and colleagues, was published in the February 20 issue of JAMA. The Diet Intervention Examining the Factors Interacting With Treatment Success (DIETFITS) trial which started off with 609 participants over a 12 month period determined the following.
No significant weight-loss differences were seen between the low-fat and low-carb groups, and neither genetics nor insulin production could predict weight-loss success on either diet. There were also no significant differences between groups for most other health markers tested.
The key to weight loss is to find a diet that you can adhere to long term, be it low carb, low fat or something inbetween. Look at changing the way you eat as a lifestyle change versus a short term quick fix diet.
