There's a new diet that is all the rage that guarantees weight loss even if you love mac and cheese.The diet is called the Boredom Diet. It allows you to eat your favorite food, but just that food and says you will loose weight.

Researchers studied the diet by having one group of women eat mac and cheese and nothing else, and another group eat normal food.

They found that after just one week, the group eating mac and cheese was eating an average of 100 calories less per meal than the other group. Over time, that's going to lead to weight loss.

But it's gradual weight loss,and really, could you eat nothing but mac and cheese or any other single food for six months or a year? Maybe if it was pizza.
