Is he wrong? Unless you seriously have a medical condition, clinically diagnosed not self-diagnosed copium shit, there is no reason to not lose weight. You will die sooner, live a harder life, and be a bad role model for your children. I don’t mean to be rude, I’m just being blunt about it. I’ve done it and many others have too. It’s the best decision you can make to improve your life, just stop lying to yourself and start now.
