Capsinoids Promote Calorie Burning at Rest
Capsinoids (e.g., capsiate, capsaicin), the active ingredients in red pepper, are promising thermogenic chemicals that might promote fat loss. They cause a burning sensation when they touch the skin, and are used in heat wraps and analgesic balms. A Canadian study from McMaster University, led by Stuart Phillips, found that capsinoids (10 mgs) ingested 30 minutes before exercise increased metabolism, adrenaline levels, and fat burning at rest but had no further effects during exercise. The supplements were well tolerated and had few side effects. Other studies found that capsinoids prevented fat cell growth, promoted thermogenesis, reduced hunger, triggered fat breakdown, and had a small effect on fat loss. Capsinoids may be useful ingredients in weight-loss supplements. (Nutrition & Metabolism, 7: 65, 2010)
