The study in JAMA (Journal of the American Medical Association) showed that the increase in calories was the major factor in increasing body fat in people and not if it was low, normal or high protein diet. One strength of this study was it looked at actual body fat increase and not just the scale weight number or BMI, which I've pointed to problems with them before.
The diet low in protein did effect the individuals differently metabolically compared to the normal and high protein diet. They gained less weight, but their body fat went up the same. This makes sense since protein is important in developing muscle mass. You will be learning more about that during the Metabolic posts in the next few weeks.
Another study to point to keeping it simple: control your portions and balance your diet.
