Regarding exercise during IF, does it have a negative effect on your performance if you don't eat some carbs BEFORE exercise? How do you prevent the body from eating itself up for energy during exercise?
Pretty much no impact. I’ve done 18 mile runs after not eating for 36 hours and without consuming calories during the run. I feel tired but no more than usual. Also weight train fasted, no issues with performance.
The goal kind of is for the body to eat itself...eating body fat.
As for maintaining muscle mass, it seems as if keeping protein intake high while lifting heavy weights does the trick.
