Study shows that low calorie diet takes commitment

I read an article on Yahoo! over the weekend about a study performed on monkeys proves that a low calorie diet takes continuous commitment to be successful. Did we need a study to tell us this.

I will say that I think the phrase "low calorie" is misleading. If I eat the right amount of calories to maintain my weight (which is considered normal), I wouldn't consider that low calorie, I consider it "right calorie".
