There have been a few studies indicating that in people who exercise and maintain a low-fat diet, consuming large amounts of caffeine and other stimulants may slightly enhance weight loss. However, caffeine (in 6 cups of strong coffee) causes the nervous system to increase heart rate, cause jitters, irritability, insomnia and elevates blood pressure. The suppression effect of caffeine on appetite doesn't last long enough to lead to significant weight loss. Caffeine is a diuretic and increases water loss from the body, but the weight loss is not body fat. The result of numerous studies do not indicate that any weight loss from large amounts of caffeine is significant or permanent, and can be quite unhealthy. The best weight loss programs combine regular exercise, a healthy diet and reinforce healthy, life-long behaviour. More information can be obtained from Health Oasis, Mayo Clinic.
