GNC Total Lean Burn 60 is a weight loss supplement that is sold by General Nutrition Center (GNC). GNC claims that those who use this product will be able to lose weight at a more rapid rate than with a healthy eating plan and exercise regimen alone.

GNC describes this product as a thermogenic formula, and states that it can increase energy and speed up the metabolism, resulting in the burning of up to 60 percent more calories than without the supplement. The Food and Drug Administration (FDA) has not tested the manufacturer's claims.http://www.gnc.com/product/index.jsp?productId=2667934

The active ingredients in GNC Total Lean Burn 60 include guarana seed extract, black tea extract, grape skin extract, ginger root and dill weed. The product comes in the form of a tablet, and the serving size is 2 tablets.http://www.gnc.com/product/index.jsp?productId=2667934

GNC Total Lean Burn contains more guarana than any other ingredient. The jury is still out on whether or not guarana can effectively help people lose weight, although it is a common ingredient in diet pills. Guarana can be dangerous when taken in high doses or over an extended period of time, and has been known to be fatal in some cases (due to the caffeine content).http://www.webmd.com/vitamins-supplements/ingredientmono-935-GUARANA.aspx?activeIngredientId=935&activeIngredientName=GUARANA

GNC Total Lean Burn, like other over the counter diet products, is considered to be a nutritional supplement by the FDA rather than a drug. As such, there are no regulations requiring the maker to prove that this product works, or even that it is safe.http://www.mayoclinic.com/health/weight-loss/HQ01160
