Does high sugar and fatty diet, and no exercise lead to one being fat and unhealthy? Yup.
But no one forced anyone to eat that way. And with the education there is today, this life style is avoidable. People in the US are just lazy and enabled. Let's give a fat person a wheel chair because they're to fat to walk.
I remember watching that show My 600lbs life. A guys wife couldn't even get out of bed and he's feeding her fried chicken and a can of green beans. She ate it all. Bitch cant even get out of bed. Giver her ass a salad with no dressing. Again enabling. One night they went out to a Denny's. She had to be wheeled in with her wheel chair. She ordered a bunch of food. And as they were leaving, a little girl pointed at her and started to laugh. The woman broke down in tears. Well it's your own fault. I have no sympathy to those who choose to live this life style.
I eat like shit. High protein, high carb, low fat (I trim my meats). But I do enjoy bacon and Portuguese sausage. What enables me to eat all this rubbish, I work out 5x a week. If I didn't burn it off, I would adjust my diet and reduce my intake. Right now I'm on a 7K calorie diet. 4500 comes from carbs alone. Which is why when I go on vacation, I always lose about 6-10lbs by the time I return. When I was competing, I lost 56lbs in 12 weeks.
It's all about motivation. Sorry for the rant, I get triggered when people say they can't lose weight or make excuses to why they got diabetes, fat, etc...My uncle was diabetic. For years his doc was telling him to get exercise. He kept saying yeah, yeah yeah. Till 1 day he decided he wanted to do a marathon. At 1st, he couldn't even run to the end of the block. He had to stop and walk. But 1 day, he made it to the end of the block. Then the next block and so on. Fast forward to today. He has done 4 marathons and doesn't need insulin for years now. He can even eat dessert if he wants to. He kicks himself in the ass for not listening to his doc all theses years.
My other good friend suffers from gout. So bad that he can't go to work for 1-2 weeks at a time. During high school, same thing, his doc said get exercise. I offered to train him. But he was to embarrassed because I would out lift him. I told him I'll just be there for support and not even lift. He always had an excuse. Fast forward 10 years. Doc told him if he keeps up his lifestyle, he's gonna take that foot from him. This was his wake up call. He started to go to the gym and not eat jack in the box at 1am anymore. His gout flare ups have gone down and he needs to buy new clothes that fit his weight loss.
