Been doing keto for 2 weeks now and feeling good except since yesterday. Just since the last 2 days I felt a bit keto flue like in my first days. Been checking my readings and everything and tracked it back to 2 days ago where I did my first Strength training. Felt so strong, but apparently it kicked me out of ketosis. For how long should I wait before I can lift weights again without getting low reading/kicked out?
