Review: Eat More, Weigh Less
Eat More, Weigh Less: What the Experts Say continued...
On the other hand, Robert H. Eckel, MD, former chair of the nutrition committee of the American Heart Association and a professor at the University of Colorado Health Sciences Center, is doubtful. He suggests that only the most committed will stick to Ornish's routine: "Because it is so rigid and doesn't allow a lot of food choices for those used to the Western diet, not many people will stay on it for the long term. Many people get tired of eating food with such a low fat content."
Frank Hu, MD, PhD, assistant professor of medicine at the Harvard School of Public Health, is critical of how severely fat is limited on the diet. "The data from numerous studies show that it is the type of fat, rather than the total amount, which is related to cardiovascular health," he says. "Polyunsaturated and monounsaturated oils actually protect against cardiovascular incidents." For example, Hu says, Ornish advocates limiting the consumption of fish and nuts, and Hu adds, "There is strong evidence that the fat in them is protective against coronary heart disease in both epidemiological studies and clinical trials."
Eat More, Weigh Less: Food For Thought
Vegetarians, or those willing to become so for the long term, may be the only dieters who will find success with this plan. The recommendation to eat smaller, more frequent meals requires that dieters change their eating schedules, which could be difficult for some. Other than that, this plan has what it takes to lose weight and keep it off, and receives high marks from nutrition experts.
