If you’re already comfortable eating the keto way, try fasting between the hours of, say, 7 p.m. and noon the next day (keep drinking water, though!) to take things one step further. As you cut the carbs, your body no longer stores as much water as it did when it had a greater glycogen supply. Stay hydrated with water and using both food and supplements to keep your electrolyte count high. While protein is a key part of the equation, much of it can distract the body into producing glucose rather than going into ketosis.
