I had a friend ask me about the Paleo diet. I was unfamiliar with the diet at the time but he informed me he cut out carbs completely. I’m sure he wont mind me sharing his experience. He’s a 230 pound man who was on a resistance training regimen and had lost 15 pounds on the Paleo diet. He came to me because he wanted to start doing more cardio and he’s sick of what he’s eating. My response to his experience was, okay you lost 15 pounds, great! But how tired were you during this dieting. He informed me that he was sleeping 9 hours a night and he was still exhausted all the time. My response… because you weren’t eating any carbs.
