^Height weighs a lot more than width. You can't really say if a person who weighs x amount is fat or not if you don't know his height.
probably not but it alters your metabolism. You're body needs a certain amount of calories and any extra it will store as fat for later use if something happened and there was no food for a while. But the McDonalds is always there. Actually, I dont think it's just stuff like McDonalds that make you fat. Eat too much of any food any you will get fat. You don't even have to consume fat calories to get fat...you will get fat if you consume more calories than your body requires function, whether they be calories from fats, carbohydrates or proteins. You can get fat eating a shitload of candy from all the sugar. And if you drink a lot of whey protein and don't work out it'll turn into fat too.
Unless you can find a stat proving otherwise, I'm saying no. People consume more calories and get less exersise as a part of daily life.
I can't speak for morbidly obese people, but from what I've seen in women is that we can really go into denial about what we look like. Our mind's can really mask the reality of our appearance and say "it's not that bad". Some people really think they look good being very heavy. Like women who wear leggings and have all kind of rolls and bumps showing. I think the more self conscious you are, the more you are in touch with reality about how you really look, weight wise. I think a good way to really see where you are at, is with a good comparison...like when I watch work out shows with women who have very lean tight bodies. Just look at them and look at you. It's a good way to keep it real. I think a morbidly obese person can reach a level of depression and hopelessness and just keep eating and getting worse. It's very hard to look at what you are instead of what you can be.
Morbid obesity is really hard to achieve... those people eat far more calories than normal people and they never exercise. I've only known one morbidly obese person in my life and he couldn't walk for 5 minutes without taking a break. He was constantly getting people to help him with all of the things he couldn't do and was basically helpless and loving it. Anyone who would allow themselves to get up to say 400 pounds has serious psychological issues.
Different foods affect the metabolism in different ways. Like I have said before, 300 calories from fat is simply not the same as 300 calories of carbs from sugar or starchy foods. One (fat) is immediately broken down by the liver WITHOUT causing an insulin release, and immediately used by the body for energy. The other (sugar/carbs) causes an insulin release, which causes fat to be stored. Fructose cannot be immediately broken down in the body and used like fat can, and what is not used gets stored as fat. The obesity epidemic seen today is mostly the result of insulin resistance, which also happens to cause diabetes, high cholesterol, high blood pressure, heart disease, cancer, candida overgrowth, and so many other things. To say that people are fat simply because they're eating too much and not getting enough exercise is oversimplifying things a bit. It's a bit more complex than that. Simply put, the big reason so many people living in developed nations are obese is because they eat diets high in processed foods which are carb heavy and loaded with more sugar than the body is able to handle. I am not saying this is the only factor, but it's a big one. It is very hard to become morbidly obese if you're eating the right foods, no matter how little exercise you get.
^I agree with a lot of what you're saying, but regular obesity and morbid obesity are two very different things. If you're eating 7 plates of chicken and salad every day for lunch, then you're going to get fatter than someone who eats a pack of twinkies every day for lunch. It isn't what you eat so much as the portions... unless you're burning it off or constantly building up your muscles. Nutritional value mostly determines whether it goes to your muscles, becomes fat, or gets converted into energy (if you're active). And if you're not exercising/naturally muscular, it's going to go to your waist... or I guess pass right through you if you have a high metabolism.
So what causes insulin resistance? No one knows entirely, but genetics is one factor. You could be born with insulin resistance, but lack of physical activity also causes cells to be less responsive to insulin. You certainly can't blame genetics for the nearly 90% of over-weight Americans so I would tend to go with the latter. People simply aren't getting as much physical activity in their daily lives as the used to.
Eating a lot more unhealthy high calorie foods too Average American male is twenty pounds heavier than forty years ago
Yeah that certainly doesn't help.. but if you work your body hard enough you can mitigate a lot of the effects of those foods too. I believe a healthy body can be pretty damned resilient.
