The FDA has a consumer warning site that lists tainted and ineffective weight loss products ; I suspect many of those you list are among them. You are risking your health by taking them. None has been tested for effectiveness or safety.
Do not take these diet pills. Go to FDA consumer alert ( google it) and find out about unregulated diet preparations containing prescription drugs whose manufacture and dosage are not regulated. The above blog is incorrect to begin with. Xenical does not reduce appetite. It works on the intestinal tract to prevent your intestines from absorbing fat so you eliminate the fat. People who take these drug run the risk of eliminating vitamins that are fat soluable like vitamin A. You will have gas, bloating, and oily stools, very unpleasant and socially unacceptable. If you want to lose weight follow a healthy low fat diet and exercise and don't believe in these diet scam.
