I've learned over the years that anyone who claims to eat chicken breast and rice as a regular staple is lying. That's the most boring diet I've ever heard of I'd literally kms. I won't judge you if you admitted to snacking or having more cheat meals than that.
Do you have problems with digestion? If you can rule out inflammation it sounds like it might be an epigenetic/metabolic problem. Honestly chicken is so damn overrated anyway man that stuff is pumped full of soy and hormones I wouldn't be surprised if it causes problems. Maybe try fish or grass fed beef instead.
Sorry man.. you caught me out.. I was lying..
What kinda loser lies about their staple diet.. Give a man a little credit.
I don't have time to list my entire damn weekly diet here on SS, but like most men who lift weights, chicken and rice is pretty much staple for us guys.
I'm not saying I eat chicken and rice 7 days a week, hell no... But yes chicken does make an appearance usually 4x a week.. I tend to eat fish alot too, and beef steak.
As for cheat meals.. I eat clean Monday to Friday & have a cheat meal Friday night..
Other than that diet is clean.
I have been training lifting weights for over twenty years, however I believe with age it becomes more difficult to keep the unwanted belly fat off.
Thanks for the tip though.
