12 Over-The-Counter Appetite Suppressants Reviewed
Garcinia cambogia diet pills are one of the most popular weight loss supplements on the market.
Made with an extract derived from the peel of the Garcinia gummi-gutta fruit, garcinia cambogia pills are used to suppress appetite and promote weight loss.
How it works: Garcinia cambogia extract contains hydroxycitric acid (HCA), which may reduce appetite by increasing serotonin levels in your brain and reducing the metabolism of carbohydrates (12).
Effectiveness: A review of 12 studies found that participants who supplemented with garcinia cambogia containing 1,000–2,800 mg of HCA per day for 2–12 weeks lost an average of 1.94 pounds (0.88 kg) more than those who consumed placebo pills (13).
Another study in 28 people demonstrated that garcinia cambogia was more effective at reducing appetite, increasing fullness and decreasing hunger than a placebo (14).
However, other studies have shown that garcinia cambogia has little to no effect on appetite or weight loss (15).
Side effects: Though generally considered safe, consuming garcinia cambogia may lead to side effects in some people, such as headaches, diarrhea, nausea, irritability and even liver failure in extreme cases (16).
Summary Some research shows that garcinia cambogia suppresses appetite and promotes weight loss.
