Keep in mind, the Keto Diet is just that, a diet. It is meant to get where you wantbto be weight wish then add back a small bit of carbs that will keep you at your goal. Yes, you still keep that life change style, but at some point you up you carb intake just a bit. Or don't, that is up to you. But you never go back to ridiculous amount of carbs like the typical American diet has.
Everything I have read says this diet is not great for burst energy or overly training. However it is good for long and steady. So keep that in mind.
