Although watching what you eat and exercising regularly can help promote weight loss, sometimes they may not be sufficient. If you are struggling to lose weight even with a reduced-calorie diet and an exercise plan, you may want to take a dietary supplement to speed your weight loss. There are many products that may promote weight loss, but you should consult a doctor before using any of them.
Omega-3 Fatty Acids
Omega-3 fatty acids are found in fish and other foods and sold as standalone dietary supplements as well. These fatty acids are purported to have many benefits and may aid in weight loss. According to research from the November 2008 issue of the journal "Appetite," omega-3 fatty acids help improve feelings of fullness for at least two hours after a meal. This suggests that the fatty acids may help you lose weight.
Caralluma Fimbriata Extract
The extract of Caralluma fimbriata, an edible species of cactus, may help control your appetite and reduce your daily calorie intake. This can help create a large calorie deficit, which is useful for weight loss. According to research from the May 2007 issue of "Appetite," supplementation of Caralluma fimbriata extract may reduce your appetite significantly, triggering a decrease in body weight and fat.
Evodiamine
Evodiamine is derived from a fruit known as Evodia rutaecarpa. According to research published in the October 2001 issue of "Planta Medica," evodiamine exhibits similar characteristics to capsaicin, a hot pepper extract used for weight loss. The research indicated that evodiamine was effective at producing reductions in weight and body fat compared to placebo. Evodiamine may be preferable as it has no hot taste, note the researchers.
Leucine
Leucine is a naturally occurring amino acid. Although you can obtain leucine through protein supplements and protein-rich foods, research suggests that consuming supplemental amounts of leucine may benefit your weight loss efforts. A study published in the June 2007 issue of "Diabetes," consumption of leucine reduced weight gain by 32 percent and fat gain by 25 percent in animals fed a high-fat diet. In addition, the supplement reduced cholesterol levels.
