I wonder if the mechanism here is calorie cycling. IMHO it would have been nice to compare 2 days of low carbing to 7 days of low carbing.In a recent study, presented at the San Antonio Breast Cancer Symposium, British researchers found that women who eliminated carbohydrate-rich foods like bread, pasta, potatoes and rice two days a week and ate their normal diet the rest of the time lost an average of 9 lb. over four months. Meanwhile, women in a similar group who ate a 1,500-cal.-per-day Mediterranean-style diet for the same time period lost only 5 lb.
Women on the intermittent diet not only lost more weight but also showed greater improvements on other markers of health, including levels of insulin and leptin.
