That’s also my experience. I do a lot of Thai boxing and I need to control my weight to maintain my weight class. I switched from a balanced diet to a keto diet hoping for change but at the end both averaged the same. The only difference was that with the balanced diet I had to eat twice as much food to actually feel full and work out without being dizzy. Now I am walking down the path of strict calorie intake control, trying to better understand my metabolism tipping point. Working out more has no effect if it does not come with some form of caloric restriction.
