People often associate abs with ultimate fitness. Covers of men's health magazines always have a man with very low body fat % right on the cover
These magazine covers are actually quite disturbing.
Aside from promoting essentially all the behaviors I see women on this very site complain about often. Fuckboism. Objectification of sexuality. Fitness levels changing personality somehow. Vulgarity.
The level of strict dieting to get to this point is just... bad for mental health and arguably isn't actually healthy in the first place. There's absolutely no reason why 15%- 20% body fat isn't good enough to be strong and healthy:
A lot of guys try to go for 10% or less for dramatic abs. But here's the problem, go under 8% and you start killing yourself. The body needs essential fat for organ health before it begins eating the organs in leu of fat storage. And if you have no fat deposits, at all, then how will you tolerate physical activity without losing muscle mass? Eat a ton of carbs?! It isn't realistic or practical.
Ultimately your body knows what it needs. You should eat to your appetite, not to your ideal reflection in the mirror. Enjoy your food, train and be happy.
