Similarly, speaking to Women’s Health, Katie Ferraro M.P.H. R.D. said of the military diet, “The problem with cutting calories this low is that it sends your body into starvation mode,” meaning that your metabolism slows down considerably during the three dieting days. On days four to seven, when you’re eating a slightly more normal amount of food, your body goes into ‘starvation mode’ storing food as fat — possibly leading to a rebound in weight-gain.
“A study published in Nutrition Journal found that participants who ate foods high in monounsaturated fats for lunch (in this case, half an avocado) reported a 40 percent decreased desire to eat for hours afterward. Monounsaturated fats from sources like olive oil, nuts and avocados can reduce cholesterol, promote weight loss, even boost memory.” — David Zinczenko, author of the Zero Belly Cookbook
