Around my eighth month of doing CrossFit, I felt like I needed to dial in my diet more. Early morning workouts were making me so hungry, and once I got home and started eating at 7 a.m., I found myself eating all day long. The numbers on the scale were going up, and it wasn't from my muscles growing. I started intermittent fasting, and within three months of eating from noon until 7 or 8 p.m., I was able to lean out.
