Yes I agree. To build muscle mass of that degree one needs animal protein I would guess, and lots of it.
Health wise though, daughter and fam are kickass, for real. That was my real point, and to emphasize the truism everything is case by case.
I’ve posted before of my good buddy, guy aged 56, 5’10" or 11", prob…140-ish? Skinny as a rail, wiry, looks icky, build wise BUT…
- is an extreme hiker (flies all over the world -New Zealand, most recently- to do extreme hikes)
- builds his own houses (5) and does big renos (too many to count)
- rebuilds classic cars (hobby, he is a programmer by trade)
- excellent health (is a hypochondriac so sees doc regularly)
- is hyperactive (diagnosed ADHD, severe)
- is scary strong. I’ve seen him lift heavy ass car parts, tree trunks, building materials, he has moved me twice (as a favor) and carried multiple boxes of hardcover heavy textbooks with ease etc etc
whose diet consists and has his entire adult life, of processed high sugar foods, pop, chocolate, ice cream, candy, a burger once in awhile, maybe a few chicken nuggets. I have witnessed him eat an entire 1 POUND bag of M&Ms mindlessly while programming in a zone.
He IS a freak of nature, a mutant! His doc tells him “somehow it’s working for you”.
Unlike my daughter’s case I think there are very few of these types, though he surely cannot be the only one!
