Harriet Brown in Slate:
If you’re one of the 45 million Americans who plan to go on a diet this year, I’ve got one word of advice for you: Don’t. You’ll likely lose weight in the short term, but your chance of keeping if off for five years or more is about the same as your chance of surviving metastatic lung cancer: 5 percent. And when you do gain back the weight, everyone will blame you. Including you.
