Weight Loss With Caffeine & Aspirin

Caffeine and aspirin were once used in combination with ephedrine in dietary supplements for weight loss. They're also found together in pain relievers, often with acetaminophen or butalbital. Caffeine should be used in moderation, and you should use aspirin only to treat mild to moderate pain or reduce fever or inflammation. A doctor may advise you to use it for other reasons, such as heart attacks, strokes and angina prevention.

Supplements

In a 2003 study in the "International Journal of Obesity and Related Metabolic Disorders," P.A 1. Daly and colleagues found that a combination of ephedrine, caffeine and aspirin could lead to modest, sustained weight loss. However, the Food and Drug Administration, or FDA, banned dietary supplements containing ephedrine in 2004 because of "unreasonable risk of illness or injury."

Effects

Caffeine may cause slight weight loss or help you maintain your weight, according to MayoClinic.com 3. Caffeine may lead to temporary appetite suppression or increase the amount of calories that your body burns. It may also cause water loss, causing short-term weight reduction. Aspirin on its own does not appear to spur weight loss, but may increase the effects of ephedrine, according to a 1987 study by A.G. Dulloo and D.S 2. Miller published in the "American Journal of Clinical Nutrition."
