The 50-50 approach to melting away body fat utilizes both dieting and eating phases. The dieting phase requires a reduction in calories by decreasing your daily carbohydrate intake by 50% for 2-4 days. Since dieting can cause the metabolism to slow, the plan requires a single "eating" day to side-step any potential slowdown. The eating phase is a single day requiring you boost your daily carbohydrate intake to 50% higher than normal. In practice, a bodybuilder eating 400 grams of carbohydrates daily and embarking on the 50-50 rotation plan will reduce his daily intake to 200 grams for 2-4 days. Next, the bodybuilder will rotate into the eating phase and increase their carbohydrates to 600 grams (50% more than 400 grams) for a single day. The eating phase gives the bodybuilder an important mental break from dieting, prevents the metabolism from slowing and may boost testosterone, growth hormone and IGF levels to help maintain muscle mass. After a single high carbohydrate day, the bodybuilder will rotate into the dieting phase for 2-4 days. The high carbohydrate levels in the eating phase can quickly reverse muscle loss that is associated with many diets. It does so by increasing insulin levels and replenishing the muscles with their primary source of training fuel; stored glycogen. With chronic dieting, glycogen stores drop and, with a modified carbohydrate intake, insulin levels remain consistently low. A lower caloric intake, modified insulin output and lower glycogen stores are major factors influencing fat loss and can cause you to slip into a catabolic state where the body burns up protein or muscle tissue. Carbohydrates prevent your body from cannibalizing other sources of energy such as the all-star branched chain amino acid, leucine. Leucine is critical for whole protein balance of muscle tissue. If you were to chronically under consume carbohydrates, your body would end up using more leucine as fuel. This would inevitably lead to muscle loss. The eating phase I prescribe requires a large influx of carbohydrates which causes an insulin surge. This quickly reverses and abates protein (muscle) breakdown allowing you to hold the maximum amount of muscle before cycling back to the dieting phase. This plan will not get you as ripped as Ronnie Coleman's glutes but it will get you close within 12 weeks. It should lean you down enough to be within striking distance of the stage.
