I may get gruff for saying this, but as someone who IS considered obese, Fat Acceptance stuff really bothers me. :( Are all body types beautiful? Absolutely! But there is no way someone my size can be healthy until they lose weight.
Before I started on this journey, I was 250 pounds. I was far more likely to develop arthritis(and already had some joint pain in my ankles and knees, which has gotten better), diabetes, heart disease, ets. Because of my weight, my body was producing far to much estrogen and I developed PCOS. Because of amount of estrogen my body was producing, I had a high risk of developing Breast, Uterine, and Ovarian Cancer.
I know not everyone will have the same problems at my size, but it still lowers life expectancy to be this big and, statistically speaking, medical studies have shown we are at much higher risk for many cancers, infertility, joint problems, diabetes, high-risk pregnancies, etc.. Do I love my body? Yes! Do I think over-weight/obese people should be ashamed of their size or treated differently? No way! Everyone deserves to be treated like a decent human being regardless of health, body size, etc. You should love yourself where you are. But I don’t think one can claim that being 100 or more pounds over-weight is healthy unless they’ve actually had a physical exam from their doctor. :P Even if you have trouble losing weight calorie-restriction, clean eating, and exercise should help—it just might come off slower than you’d like.
By all means, love your body. I love mine. I never want to make anyone ashamed of their body. But I don’t think we can be angry when someone says being severely over-weight(and I’m not talking an extra 20-30 pounds. If you have a heavier body type, that might be normal for you.) is unhealthy or that being severly underweight is unhealthy. Medically speaking, it’s the truth.
