I've been reading up on intermittent fasting and I've been trying to figure out if its a plausible option for me. I have a pretty small frame and my goals aren't necessarily to lose weight but more so to gain lean muscle mass. I am 22 5'4" and I weigh 108. I Crossfit about 4-5x a week and have been following paleo for about 6 months now.
I just can't seem to wrap my brain around not eating for an entire day or only eating one meal as a healthy idea for me. Can someone break it down so that I can understand how this would help me reach my goals. I am very interested to know more. . .
