Study finds women lost more weight cutting carbs two days a week than a full …

Do you want to lose weight but aren’t quite sure you’re ready to commit to a full-time, seven-days-a-week diet?

Well, good news then.

Researchers out of Britain found that women who gave up carbohydrates such as bread, pasta, potatoes and rice just two days a week,  eating their regular diet the rest of the time, lost almost twice as much weight over a four-month period as women who ate a 1,500 calorie per day Mediterranean-style diet every day. The researchers were looking at the connection between obesity, hormones such as insulin and leptin and breast cancer. From Time:

All 115 women who participated in the study were at high risk of breast cancer based on their family histories of the disease. They were randomly assigned to one of three diets: a two-day-a-week low-carb diet that restricted calories to 650 on the carb-free days; a similar low-carb diet, except with no calorie restriction (participants were allowed to load up on protein and healthy fats, such as lean meats, olives and nuts, on no-carb days); or a standard 1,500-calorie-a-day Mediterranean-style diet seven days a week.

Both intermittently dieting groups lost more weight and saw more improvements in insulin resistance, compared with the Mediterranean-style diet group. The group that ate the calorie-restricted, low-carb diet fared a little better when it came to insulin levels, however, reducing insulin resistance by 22%, compared with 14% for the unrestricted low-carb dieters and 4% for those on the Mediterranean diet.

The researchers said the results were compelling enough to warrant further study on the relationship between carbohydrate consumption and breast cancer.

The women who ate the low-cal, low-carb diet lost an average of 9 pounds over the four month period while the women who ate the Mediterranean-style diet lost only 5 pounds.

(Does anybody else think restricting your diet to only 650 calories and no carbs two days out of the week would actually be really difficult to do?)
