"The study assessed more than 4,000 people in the United States, Britain, Japan and China, asking them to write down everything they had eaten over two 24-hour periods.

"Lo and behold, what we did find is that without exception, a high complex-carbohydrate, high-fiber, high vegetable-protein diet was associated with low body-mass index (the standard measure of healthy weight)," Van Horn said.

The more animal protein a person ate, the higher his or her weight, she said. "


I was interested in their comment that increased protein intake also meant increased weight gain. It is unlikely that their study isolated people who cut out starchy carbs with their protein so as to be able to speak of protein as a factor in isolation! What they need is data from people who have followed a low carb higher protein diet for over two years. If the eaters studied ate rice and/or potatoes with their increased protein, then the higher weight is not surprising. Its just a question of you juggle the figures.
