I am trying intermittent fasting for the offseason. No reason other than something to test since I am borderline mental about nutrition/calories.
I am trying the 16:8 fasting schedule. Been doing it for 5 days and it is working pretty good. But, I am getting exhausted in my morning swims. Luckily, I have always ran in a fasted state when training. I just always ran before breakfast.
But now, I am eating at 7pm, then not working out until 8am and I just dont have the energy. No way I could do a two hour bike ride.
For those of you who do 16:8 and workout in the morning, how do you get through your workouts?
Most I do is 16 hours fasted [2pm-8AM] once a week [allowing water and caffeine, though, can't skimp on caffeine].
I have no trouble getting thorugh the first workout of the day, but if I bike fasted, then eat, and try to swim at lunch, I'm wasted. I'm pretty much ready to concede that I'll only be working out once the day I come off the fast. I don't think there is any way I could do 16:8 daily.
