WHEN it comes to packing on body fat, the volume of calories you ingest seems to count more than whether those calories come from lots of protein, or very little.
US researchers found that people who ate high-calorie diets all gained about the same amount of fat.
Those whose diets were low in protein gained less weight overall than people on high- and moderate-protein diets, but that's because the low-protein group also lost muscle. "Huge swings in protein intake do not result in huge swings in body fat gain," said Dr James Levine, who studies obesity at the Mayo Clinic in Rochester, Minnesota but wasn't involved in the new study. "It really is the calories that count."
Previous research has suggested that when people overeat, the amount of weight they gain varies from person to person.
The current study was conducted by researchers led by Dr George Bray from the Pennington Biomedical Research Center in Baton Rouge, Louisiana.
"People who had the low protein gained about half as much weight as those that had normal or high protein, but the weight was different in one major component: they lost body protein, which is not healthy," Bray said.
"The scale can fool you into thinking that you're winning when you aren't."
