I've been on keto for several months. I work out a lot and the results were great. I lost a lot of weight and looked more defined. Then I hit a plateau. My search for an answer led me to learn about carb cycling. I'm eating some carbs about once a week to fill up my depleted glycogen levels. Basically it gave me a boost of energy and strength and my muscles got bigger and more defined. Then back to keto for another week. I'd recommend doing research on carb cycling. Good luck.
