Although ketogenic diets are useful for fat loss, while simultaneously sparing muscle loss, they have one significant drawback: they cannot sustain high intensity exercise. Activities like weight training can only use carbohydrates as an energy source, ketones and free fatty acids (FFA) cannot be used. Therefore the lack of carbohydrates on a ketogenic diet will eventually lead to decreased performance in the weight room, which may result in muscle loss, and carbohydrates must be introduced into a ketogenic diet without affecting ketosis. Probably the most common way to do this is to do a weekend carb-load phase, where ketosis is abolished. During this time period, assuming training volume was sufficient to deplete muscle glycogen (see last article), the body can rapidly increase muscle glycogen levels to normal or supra-normal levels prior to beginning the next ketogenic cycle.

Training on the Cyclical Ketogenic Diet: Effects of Cyclical Ketogenic Diets on Exercise Performance
As the Cyclical Ketogenic Diet (CKD) becomes more popular among natural bodybuilders, a great many questions have arisen regarding any and all manners of topics. One of the primary has to do with exercise on a CKD. First and foremost, individuals want to know what types of exercise can and can not be sustained on a CKD. Secondly questions arise as to what is the optimal training structure to maximize either fat loss or muscle gains on a CKD.
