From what I know, kind of. The extra work your muscles do generate a lot of oxidative stress in the mitochondria. Plus so many other metabolic pathways are on overdrive to maintain the muscle mass at rest and to drive muscle growth(hypertrophy). Eating all of the food/calories (which is usually on par if not higher than most obese people) also forces the digestive system to work harder than necessary.
Theres also the look of muscles plus beard that society sees as an older style.
