Yeah I guess it's never been an issue with you because you've never tried to lift as big as you can.
Just regulating it via food and the weight lifted.
I still think time plays a massive part though. 9 years you've been at it? Maintaining you don't have any goals as such, so you're not trying to achieve any feats. if you get 'fatter' than what you like you can just switch back to what you've always done and sacrifice something.
What if you wanted to hit 200kg deads, whilst maintaining same bf percentage and not feeling fatigued and eating your favorite foods?
Do you think it would be worth knowing a bit more about what the make up of your food is? To achieve it quicker?
A lot of people do cuts, lose strength, get cranky and it only lasts a month because it's not sustainable
