Fasting, twice a week, used to be very strict but then dropped back to just having some tea.. fasting is very powerful, gave me my mojo back in mid 30s after burnout from top tier consulting firm and grad school, got testosterone boost, clarity of mind, physical fitness and confidence, amazing tool.. but body has to be of the right disposition.
How many hours are you fasting? Whole day twice a week?
Used to be just water for the whole day. Maybe some electrolytes, potassium, sodium salts.. lately I’m caffeinating to get through the workload
