People resolving to lose weight in 2012 shouldn't cut back on protein, research suggests.
Although the high-protein diet craze isn't the hot trend it was a few years ago, it might be due for another look.
New research from the Journal of the American Medical Association finds people lose lean body mass (muscle and organ tissue) on a low-protein diet and but gain lean body mass on a normal or high-protein diet, according to a report in USA Today.
The JAMA study aimed to evaluate overconsumption of low, normal and high protein diets on weight gain, energy expenditure and body composition.
For the trial, 25 weight-stable male and female volunteers ages 18 to 35 with a body mass index between 19 and 30 ate diets containing 5% of energy from protein (low protein), 15% (normal protein), or 25% (high protein), which they were overfed for eight weeks.
Participants' dietary consumption was raised by approximately 40% -- an increase of nearly 1,000 calories per day.
The Institute of Medicine recommends a diet (based on 2,000 calories daily consumption) containing a range of 10% to 35% of calories from protein, which the U.S. Department of Agriculture's MyPlate guidelines recommend as 5-6.5 ounces of protein foods a day for adults depending on age and gender.
