I did a little more digging on fat acceptance, and I have become further disturbed by the trend. Many followers refer to the Junkfood Science blog to justify things. While the blog actually demonstrates critical thinking, many of the studies cited are for isolated events. For example, if a person is involved in a physical trauma, then extra body fat may improve their survival rates. All the blog does is show that fat is not bad in all cases, but it does not show that 1) being fat is better than being in-shape over the course of a lifetime, and 2) being overweight or obese is an incurable condition.
Here’s a subject that I bet gets swept under the rug in terms of fat acceptance: sex. Evolution is all about mating and reproduction, and evolution is really "pulling the strings" in most human behavior. This study shows that those who are obese have a reduced sexual quality of life. And numerous studies show that being overweight or obese reduces the chance of conceiving for both men and women.
This is bad news for anyone who is overweight, but the good news is that losing weight is possible. Really. And the people who waste their time writing about fat acceptance would be better off trying to help people who do want to lose weight.
