I went keto/paleo in 2011, carnivore in late 2018. The first few months are the hardest, but I still struggle with cravings at times. Never do cheat days either.

I've gone through an amazing transformation since, but I still don't feel satisfied with my body. I walk every day, lift weights 3-4x weekly, intermittent fast, and eat ~2100 calories/day. Still have belly fat that I can't get rid of. It's frustrating.
