If you're turning to diet pills to help you shed those extra holiday pounds, be warned the FDA says many are a risk to your health.

From Venom Hyperdrive to Imelda Perfect Slim and 2 Day Diet the list of weight loss pills goes on and on. "Those are typically various forms of stimulants," says, Dr. Rollins with the Integrative Medicine Center. Dr. Rollins says a stimulant will curb hunger but there can be side effects. "You will see people have more anxiety, its hard on your adrenal gland which is part of your stress system."

Not to mention the weight usually comes back says Dr. Rollins. "It definitely returns so its not a long term solution."

Now the Food and Drug Administration has listed nearly 30 weight–loss pills that can cause serious health risks. In fact the FDA has only approved one over the counter weight loss pill. Its called Alli.

Dwayne Horn is a personal trainer for Crossroads Fitness and says many people come to him after the pills fail to deliver. "All the time, you get that all the time, people come in, 'Dwayne you know I tried this it's not working."

Horn says it takes time and dedication to see real results. "Three weeks is usually some water weight, but once we get to 4–6 weeks we usually see some body fat and stuff of that nature coming off," says Horn. Which may not be a quick fix but definitely a more permanent one.
