A four-nation study of more than 4,000 men and women ages 40 to 59 has produced a stunning conclusion in our Atkins Diet-fueled society: The thinnest people on Earth eat the most carbohydrates. Even more alarming, the people who eat the most protein are actually the heaviest.

‘Without exception, a high-complex-carbohydrate, high-vegetable-protein diet is associated with low body mass,’ study leader Linda Van Horn of Northwestern University said in a news conference reported by Reuters. ‘High-protein diets were associated with higher body weight.’ However, before you think you have the green light to raid Krispy Kreme, realize that the carbs that do a body good are complex carbohydrates such as whole grains, fruits, and vegetables.
