Here’s how they work

For Weight Watchers, it’s about controlling portions through a daily point allotment. For Atkins and South Beach, it’s about eating fewer carbs. Other diets have you eating more fiber or watching fat intake. But no matter how fancy the diet or involved the program, what it all boils down to is eating fewer calories.

DIY!

Who needs a one-size-fits-all diet plan when you can do it yourself? We’re not saying some people don’t find diet plans helpful, but it’s really about cutting out high-calorie habits. So think about where you can scale back. Lots of sodas and juice drinks are loaded with calories. Same with fast foods. Serving yourself a mondo portion packs calories. Do you only eat fruit once a week? Do you add extra cheese or butter to everything? Instead of following a rigid plan, substitute an unhealthful habit for a better one. Stick to water and skim milk. If you always eat cookies and candy, go for nuts and fruit instead. Eat smaller portions, and add veggies.
