Why did you decide to do so much in one go, just the fast or just the exercise.Its a terrible idea and you cant keep it up.
I gym (weights) 5 days a weekDid omad last week 800kcals instead of my normal 1800kcals. I stopped gyming for the week.Lost 10lbsOff omad yesterdayBack to gym today(im 100% aware that i didnt lose 10lbs of fat and about to lbs of it will be water)
Small simple steps works 100% of the timeDoing everything in 1 go fails 99% of the time
Stop being so inpatient
Are you taking !electrolytes (see auto reply below)..
Exercise on longer fasts can be a little challenging. Do what you feel comfortable doing. Push a little, though. You are training your body to metabolize fat.
It gets easier with fasting experience. Your body gets more used to being in a fasted state.
