Except I was working in a wood shop, lifting huge piles of wood, doing regular farmer carries, constantly squatting and bending, and had a layer of blubber over my muscles. I had no sloth, but eating SAD kept me obese (and inflamed, with boils all over, sleep apnea, you know the story!).
As a kid, I was riding my bike, doing push-ups, and NEVER made progress.
I had no car in my teens, I walked EVERY DAY, EVERYWHERE - I'm talking 6 hours of walking every day. If I had a bicycle I hadn't completely worn out or destroyed yet, I rode IT for hours a day. And I stayed FAT. Because I was ALWAYS hungry. I looked at people who left food behind like they MUST be insane. Every chance I got, I ate all the food I could. I knew which dumpsters to hit on which days for fresh pizza, etc.
I give sloth NO cred at all, based on my N=1.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
