Garlic has been used as a form of alternative medicine for thousands of years. It may be beneficial in the treatment or prevention of heart disease, the common cold and cancer, according to the University of Maryland Medical Center. Preliminary results suggest garlic may also be beneficial for weight loss, but further research is necessary to verify these effects and determine the amount of garlic necessary to produce weight-loss results.
Potential for Calorie Burning
A study published in "Nutrition Research and Practice" in June 2012 using aged garlic extract found that taking 80 milligrams per day of this supplement for 12 weeks helped women lose weight and reduce their body mass index. Don't count on garlic to help you lose a lot of weight, however, since study participants only lost about 6.6 pounds, or about 1/2 pound per week during the study. Garlic may increase the number of calories you burn during your daily activities and decrease your body's production of fat, notes another study published in "The Journal of Nutrition" in September 2011. Before trying garlic for weight loss, check with your doctor to make sure it is safe for you. Garlic can interact with certain medications, such as blood thinners, birth control pills, nonsteroidal anti-inflammatory drugs and medications for tuberculosis and human immunodeficiency virus.
