4 Popular Weight Loss Supplements

When choosing a weight loss supplement, it is important to research several. This review identifies some of the facts about four of the most popular products: Alli, Lipozene, Hydroxycut, and Burn XT.


Orlistat is the active ingredient in Alli and helps an individual lose weight by decreasing how much dietary fat the intestines absorb. Orlistat prevents the enzyme, Lipase, from breaking down dietary fat and storing it. Instead, approximately 25 percent of fat is eliminated in the form of bowel movements instead of being broken down.

While Alli may allow you to lose weight, it is unlikely to be significant—probably only a few pounds more than would be possible with just a reduced calorie diet and regular exercise regimen. The increase in weight loss averaged 5.7 pounds over the course of one year compared to those who did not use Alli.


Lipozene is a weight loss supplement that is comprised of a water-soluble fiber called Glucomannan, the only active ingredient. This fiber is able to absorb a substantial amount of water and turn it into a gel. Observational studies have shown those who consume more dietary fiber usually weigh less. The absorbent properties of Glucomannan allow it to form a thick gel in the stomach thus giving the user a feeling of fullness even when eating only small amounts of food.

A five-week study of 176 people was conducted. They consumed a 1,200-calorie diet and took either a supplement containing Glucomannan or a placebo. Those taking the supplement lost approximately 3.7 pounds more than the placebo group.


Hydroxycut is a weight loss supplement that is available in several forms including pills, capsules, and gummies. The active ingredients are caffeine, komin, lady’s mantle extract, wile mint extract, and wild olive extract. It also contains some minor ingredients that include caffeine.

Numerous studies have been conducted that have shown caffeine can boost metabolism as much as 11 percent and enhance fat burning as much as 29 percent. However, these are only short-term effects, and users will soon develop a tolerance to caffeine. There are no studies that provide evidence caffeine is helpful for weight loss over the long-term. Further, no research has been conducted on the effectiveness of the herbal ingredients for weight loss.

Burn XT

Burn XT has been formulated for both men and women and works in different ways in order to support the goals of the user. The ingredients in this supplement include green coffee bean extract, Glucomannan, Chromium, and Vitamins B6 and B12. There are over 2,000 reviews of Burn XT on the Amazon website with an average rating of 4.4 out of 5. According to one reviewer, it was a great addition to the daily routine and worked fairly quickly. However, someone else said it was only effective if you follow the directions on the label.


Conduct your own research before deciding on any weight loss product. What works for someone else may not work for you. Also, keep in mind what your goals are and choose the product you feel is best able to help you meet those goals.
