3. Low carb = low energy
Going low carb can be tough on your exercise regime. When there is inadequate glucose (carbohydrates) in the bloodstream or muscles during exercise we tend to 'hit a wall' and exercise gets harder or you stop and go home. This is why endurace sports, which exhaust your carb stores, usually recommend sports drinks or gels, which give athletes the glucose boost they need. But, on a ketogenic diet, your body will eventually learn to burn fat more efficiently.

A recent study published in the European Journal of Sports Science suggests that lowering carbohydrate intake and increasing fat for several weeks will result in what's called 'keto-adaption' and better fat burning.
