When you say that you hate to fat shame someone then you immediately start fat shaming the person, it really undermines your credibility. I'm sure that you know that as you get older, it gets more challenging maintaining the physique you had in your 20s. In addition, if you bulk up and don't maintain a regular routine, the muscle can easily turn to fat, especially if you didn't have to work hard for it before. I remember my dad having six-pack abs well into his 40s and I have never seen him exercise or lift anything but a beer. Conversely, my step father didn't drink, was a full-time personal trainer, and worked out regularly but he had the most difficult time getting abs.
