So . . . IS a calorie a calorie or not?

Let’s take a look at the latest published study regarding the effects of 3 different eating plans on maintenance of weight loss.

Study Details

Twenty one overweight and obese, but otherwise healthy, adults first went through a weight loss phase, all of them losing 10-15% of their initial weight.  This was followed by a 4 week standard maintenance plan, the same for all participants.

The study then had each individual follow three different diets for one month each (in random order), with followup to keep calorie levels appropriate for maintenance.

Researchers found that those on a low carb plan (10% carb, 60% fat, 30% protein) maintained weight  eating more calories than those on a low glycemic index diet (40% carb, 40% fat, 20% protein) or a low fat diet (60% carb, 20% fat, 20% protein).  The difference was statistically significant, with about a 300 calorie difference in total calories burned between the very low carb diet and the low fat diet.  The low glycemic index diet resulted in maintenance metabolism values between the other two.
