I for one am not putting something in my body that I bought from a shady online retailer that may or may not be what it they say it is because OTC steroids aren't legal. However, if my doctor would prescribe them to me, sure I'd take a crack at a cycle or two.
Secondly, "good" diets and "bad" diets are relative terms like budgets. If my budget allows me to drive a $80k truck towing a $75k boat to my $400k lake house, but I'm in debt up to my eyeballs and can barely make the interest payments, well no one sees that except for me and the credit agencies. So that may sure look like a great budget, but it's deceiving. Diets are reflective of someone's individual genetic makeup and their goals. Bowmar could drop dead because of his diet when he's 62 instead of 72 or 82. Maybe he won't. But if his primary goal is shredded abs
now and absurdly low bodyfat to sell* veggie powder and other supplements then his diet sure seems to work for him.
I think there is a ton of good research out there now and there is a ton of bad pseudo-science. I switched to keto last year after watching a pretty in-shape guy in my office drop 40lbs like
nothing. I felt different and it sure helped me lose some weight, but I didn't have a miraculous transformation. Different strokes for different folks. I do think it's wise to moderate carbs because they're so calorically dense. But I want some in my diet to provide sufficient glycogen. The keto diet is forcing the body to run on ketones. Those two fuels get the body to go the same place, but the systems are different. If I eat carbs they're usually from in order: leafy greens, root vegetables, potatoes, corn, oats, gluten/wheats, fructose, and sugar/glucose. I like to minimize the starches and sugars, but damn, french fries are delicious.
*One of my favorite places in the Adirondacks is Lake Lila, it's a wilderness area that used to be a 23,000-acre playground of
a wealthy dude in the early 1800s. He made a fortune selling "diet" pills. Ain't nothing new under the sun.
