You’ve likely seen the headlines on calorie restriction, or a “permanent diet“, increasing the lifespan of monkeys. Turns out some research is being done on human volunteers, too — and it’s not without problems:
[I]t has potential downsides, including constant hunger, sensitivity to cold, weakened immune function and sour mood, says Susan Roberts, professor of nutrition and psychiatry at Tufts University, where she is leading a study on calorie restriction diets.
Gee. I don’t remember reading about those “potential downsides” in diet books, though I’ve certainly experienced them. Wonder why that is?
- The assumption that fat people always always overeat and dieting is just about learning to eat normally?
- Fear of discouraging the poor fat suckers people who so need the benefits of dieting?
- Assuming that these downsides (and others) only affect people who are already thin, so fat people are immune?
