Carb Cycling.
This approach allows the athlete to either gain maximum muscle mass without gaining too much fat (sometimes a slight fat loss is even possible) or to get into contest shape while maintaining (or even gaining) muscle mass. The strategy is actually not complicated and it's the most effective way to diet
The Logic Behind the System
There are two inevitable truths when it comes to building muscle or losing fat:
1) To increase body mass you need to consume more calories than you use.
2) To lose body fat you need to consume fewer calories than you use.
Obviously, the type of food you ingest will have an important impact on the end result. If the bulk of your calories come from junk food, chances are you'll end up gaining more fat than muscle. Similarly, if the quality of your food intake is low while dieting, chances are you'll end up losing more muscle tissue.
