NEW YORK (Reuters Health) - Low-carb and high-carb diets work equally well for maintaining weight loss, Australian researchers report.
People had the same success in keeping off the weight they'd lost after sharply cutting their calorie intake for 3 months if they followed a low-carb (also called high-protein) diet or a high-carbohydrate regimen for the following year, Dr. Elizabeth A. Delbridge of the Heidelberg Repatriation Hospital in Victoria and her colleagues found.
Some studies have suggested that high protein diets may be a more effective way to lose weight short-term than high carbohydrate diets, Delbridge and her team note in their report. But there's less evidence on which approach might be better for helping people to keep off weight they've lost, and whether the two diets have different effects on heart health.
To investigate, Delbridge and her team assigned 141 men and women who'd completed the weight-loss phase of the diet to a year on a diet in which 30 percent of their calories came from protein, or one consisting of 15 percent protein. Both groups also were instructed to keep their fat intake below 30 percent of total calories, and to focus on reducing saturated fat.
