Cayenne pepper may help with weight loss by increasing metabolism and reducing appetite. The main active ingredient in cayenne pepper is capsaicin, which has a thermogenic effect that can help burn fat. One study found that taking 4 mg of capsaicin for 12 weeks resulted in a 6% reduction in body fat. Cayenne pepper can be consumed in various ways, including as a drink with lemon juice, maple syrup, and water. However, it is important to note that cayenne pepper alone is not a magic weight-loss solution and should be combined with healthy eating and exercise habits. Other herbs that may be beneficial for weight loss include ginseng, cinnamon, black pepper, and turmeric.
