Does the program help you change long-term eating habits?

If not, you'll just get caught up in a never-ending lose-gain cycle -- better known as "yo-yo" dieting.

Most diets are short-term fixes for a long-term problem, says Zelman. "People who get slim and stay that way have changed their eating habits and attitudes toward food."

Does it involve exercise?

If it doesn't, you will gain the weight back. "Research shows that individuals who exercise on a regular basis have much greater success at losing weight and keeping it off ... Exercise is critical to weight loss success," Cedric Bryant, PhD, chief exercise physiologist for the American Council on Exercise, tells WebMD.

You need an hour of aerobic exercise -- at least five times per week -- if you seriously want to lose weight, says Bryant. "That doesn't need to be in one concentrated dose, because calorie-burning effects accumulate over time."

Also, you need strength training two times a week to build muscle. Lifting weights or working with rubber tubes helps maintain and can also increase the level of lean body mass -- which helps your metabolism burn calories.

"Two-thirds of the calories a person burns over the course of a day are from resting metabolism," says Bryant. "If you're on a restricted diet (decreasing calories and nutrients) and not doing resistance training (to build muscle), it's not uncommon to see resting metabolism decrease -- so you won't lose weight."

Are supplements, creams, or patches involved?

If so, forget it. "It's the old saying, 'if it sounds too good to be true, it is.' Why would we have an obesity epidemic if it was as easy as popping a pill?" says Zelman.

"By and large, products are not capable of helping you lose weight. Ephedra has been banned from the market, and it was the major ingredient of weight-loss supplements." That should send a big message: These things are either not healthy or do not work, she says.

Products that block absorption of fat, such as Xenical or Orlistat, may have only minor weight-loss potential -- and they're expensive, says Zelman.

The problem: "These are all Band-Aid approaches to the problem. Even though it's not sexy, and not any fun, people know what they need to do. You don't need to be a rocket scientist to know that eating sweets, eating constantly, drinking alcohol, eating fast food are all the things that add extra calories."
