people are overweight because they take in more calories than they burn. that’s it. there is no other reason. things affect your calorie burn rate. how peppy you are. a very few rare conditions. genetics. but basically, yeah, you are overweight if you eat more than you burn. You could run and exercise a lot but if you eat more than you move, you gain. “Lazy” is kind of judgmental and it assigns fault. It’s not laziness per se that causes you to be obese; it’s society, attitudes, food everywhere, culture, no exercise options. If you put a rat in a cage, gave it unlimited calories and didn’t let it move, it would porbably get large too. How large depends on the rat. But obesity’s not some virus you catch, either. Obesity is just so awfully depressing and it’s so depressing that health care issues are inextricably intertwined with moral jugdments. it’s making me sad and rethinking my need for a zoloft prescription. i try not to feel morally superior as a thin energetic person, but i find myself sometimes falling into that. That tendency makes me feel icky.
