I remember a heavyset individual from work many years ago. He’d eat a huge lunch (three sandwiches, a few apples and bananas, several Hostess snack cakes and such) and then chug a can of Ultra Slim-Fast. I don’t know if it ever worked, but I’d guess not.
I also had similar where I used to work, minus the slim-fast.
Notoriously glutonous eater, probably in the neighborhood of 400 lbs.....all the while relegated to a 3 wheel mobility scooter.
Some people just never grasp the concept of taking care of the physical body.....while unbelievably resilient, it can only take so much.
