I get so tired of gimmicky, unsafe and ineffective products promoting unrealistic promises of trim waistlines and washboard ads.

The best way to lose body fat—assuming a healthy metabolism and the absence of certain medical conditions—is still to burn more calories than you eat over time (about 500 calories per day). In my experience a deficit greater than 500 calories usually doesn’t work. Eating too few calories leaves you hungry and can lead to bingeing, may leave you too tired to exercise and, in some cases, can slow your metabolism making it permanently harder to shed body fat.
