How Do Most Weight Loss Pills Work?

There are so many weight loss pills available in the markets today. While some are synthetic, others claim to be natural. Some use probiotics while others use herbal ingredients like green tea. Some weight loss pills can be obtained over the counter while some can be obtained only with a doctor’s prescription. The question is, do these pills work

Appetite suppressants like sibutramine or diethylpropion work by sending satiety signals to the brain so that you feel full and eat less.

Fat blockers block the action of the enzyme lipase which is responsible for the breakdown of fat molecules. By preventing the breakdown and absorption of fats, these lipase inhibitors ensure that fat from the intestine is removed through bowel movements. One thing to remember while using such pills is to eat low fat foods. Excess fat intake while using lipase inhibitors, can cause bloating, cramping and diarrhea.

Then there are over the counter diet pills which contain natural substances which help you lose weight by suppressing the appetite, boosting metabolism and improving the rate at which fat is burnt by the body. Most of these diet pills contain compounds like caffeine, herbal ephedra, guar gum, hoodia, green tea, chrominum, chitosan etc. Chitosan and guar gum work by blocking the absorption of fat in the intestines while chromium reduces body fat and helps build muscle. Green tea boosts the metabolism while ephedra and hoodia decrease appetite.

Weight loss pills help the body lose weight if combined with a good diet and exercise regimen. These pills are meant to aid in weight loss.
