In my experience, best to muscle through the body's transition from running on carbs to running on fat. Sometimes you get 'keto flu' but there are great recipes for keto lemonade to get through it. I stuck with it for 30 days and found my cravings (beer, salty/crunchy snacks like potato chips) disappear, I was far more energetic, and needed to eat far less often. I lifted and rowed right through without any issues after that first week or so of 'keto flu' / detox.
