It's not just how many calories, but what kind, study finds - latimes.com:

"...from a metabolic perspective, all calories are not alike," said study senior author Dr. David Ludwig, director of the New Balance Foundation Obesity Prevention Center at Children's Hospital Boston. "The quality of the calories going in affects the quantity of the calories going out."

and later:

"...each subject was fed three different diets for four weeks at a time: a traditional low-fat diet (60% carbohydrates, 20% fat and 20% protein), a low glycemic index diet (with 40% carbs, 40% fat and 20% protein) and a very low-carbohydrate diet a la Atkins (with 10% carbohydrates, 60% fat and 30% protein).

the results? The low fat diet had the most severe metabolism reduction.

FYI this is very similar to what Metabolic Effect has been preaching for a while now! :)
