There's something called 'keto flu' where for the first week or two you can feel a little off while adjusting, but afterwards you have plenty of mental energy, as long as you keep your electrolytes up. All previous diets for me failed because I always felt like I couldn't think and do my job and needed to flood my system with calories in order to keep going... on keto I haven't had that feeling even once.
