I have a friend who made ability to lift heavy stuff basically his whole identity. Correlated with that was at any gathering he made a big show of eating just way more than everyone else because he’s a “big guy” and his muscles demand that much. So long as he could lift, obviously he must be fit, he works out after all. Basically his concept of masculinity is lift the heaviest stuff and eat the most stuff.
Now he’s struggling with diabetes and liver problems, despite being crazy strong. Never did cardio, and ate way more than he needed.
Yes, BMI can be misleading and being a bit muscular can have a higher BMI and be healthier than BMI says, but odds are if you are up in the obese territory, you probably are packing a lot of visceral fat screwing up your gut.
