With the TNT Diet, the magic word is glycogen, the carbohydrates stored in the muscle. By reducing the amount of glycogen, the body knows to turn to fat as the main source of energy. Not only does that unwanted flab become to dissipate, but this also launches a process known as nutrient partitioning.

With nutrient partitioning, calories are diverted from the fat cells and to the muscle cells. By lowering glycogen levels, the body's response to insulin is altered, allowing it to signal the body to build muscle without burning fat.

The makers of the TNT Diet encourage dieters to concentrate on the type of carbs and the time carbs are eaten. That's why they've created three Time Zones -- The Fat-Burning Time Zone, the Reloading Time Zone and the Muscle-Building Time Zone.

The Fat-Burning Time Zone is a low-carb diet that speeds fat loss and regulates appetite. Followers will spend most of the week in this time zone, which is the foundation of the plan. In the Fat-Burning Time Zone, followers can consume all of the veggies, meats, cheeses and eggs they want. By limiting the number of carbs, the body is kept in fat-burning mode.
