I'd trust anything French. /sarcasm
There is a proven weight loss system: eat healthy and exercise. Does wonders.
True, it really does. I've been doing about 15 minutes worth of exercises everyday with very light weights for a while now. I've lost 2 kilograms(about 4 pounds) in a month, and also feel a lot healthier. Besides, exercise is the best method of preventing sleep when doing activity that demands concentration.
Hope it inspires others to do the same and more. Your body deserves it! All the best!
And one more thing. Before anyone jumps the board to go for short-cut methods to lose weight, a word of caution. A lot of these drugs are known to cause side effects in the long term, some of which include loss of libido, trembling hands and feet, etc. Most of such symptoms are discovered very late- about 15 to 20 years after the introduction of a drug. Take the example of birth control pills.
