Narrator: This is Science Today. You've probably seen or heard about those rapid weight loss products on the market. While they may seem tempting to some, University of California, Berkeley nutrition expert, Joanne Ikeda says people should be immediately skeptical when they see product claims for rapid weight loss in a short period of time.
Ikeda: An ideal weight loss program - your goal would be one to two pounds a week, so the most you would lose in a month is eight pounds maximum. The other claim that's often made for these products is you won't have to change your eating or exercise habits. That you can go right on living the same lifestyle, eating the same food you've always eaten, sitting on the couch most of the time watching TV and the fat will melt off your body. Now, I'm sorry but the law of physics said that that's not going to work.
