I love how people associate being "fit" with being healthy, when there's plenty of "fit" people doing unhealthy things. Like taking ungodly amounts of creatine, whey protein, BCAAs, pre workout, energy drinks, steroids, human growth hormone and other things thar arent the best for your liver and kidneys. Lifting, pressing, squatting, and curling extremely heavy weights, putting unnatural pressure on joints. But nope Andre over there has an 8 pack and 22" biceps, he's healthy as a fiddle.
Like someone mentioned previously, I think it's time to stop looking at others and trying to determine what's best for them etc; I've known people who lived a "healthy" lifestyle and still had health problems and have seen obese people live into their 90's-100's.
I agree America's food system is terrible, so it's kind odd when I hear people suggest obese people should just flip a switch and change their lifestyle. And calling people whales is just a whole 'nother level of ignorance and child like behavior.
