You may recall that Gary Taubes recounted some over-feeding studies in Good Calories, Bad Calories. The upshot was that naturally thin people don’t gain as much weight or extra bodyfat from over-consuming food as the “3500 calories equals a pound of fat” equation says they should. Their bodies adjust. The same works in reverse: people who cut calories often don’t lose as much weight as the calorie equation says they should. Their bodies adjust as well. The calories in affect the calories out.
Someone on YouTube suggested I watch this BBC documentary about a researcher who conducted a similar experiment: a group of naturally-thin young adults doubled their normal caloric intake for four weeks. Sure enough, some gained about what you’d expect, but others gained significantly less. One barely put on any extra bodyfat at all.
Most of them reported easily losing the weight they’d gained once they stopped the experiment — and no, they didn’t count calories. They didn’t need to. Their bodies are geared to resist becoming fat, so they just returned to their normal eating behaviors and dropped the weight. That’s what happened to Chareva after both of her pregnancies. A month after delivery, you’d never know she’d been pregnant to look at her.
As if to demonstrate just how pig-headed people can be about this topic even after the evidence from a controlled study is presented to them, some genius left this in the comments section for the documentary:
this is the most moronic documentary ever.
eat more than your body burns = gain weight, vice versa
END OF STORY
The genius is probably one of those people who never gains weight and thinks it’s because of his superior discipline. Or as I’ve put it before, he was born on the finish line and thinks he won a race. (He no doubt believes he’s qualified to tell others how to win the race as well. But enough about Dr. Oz.)
I trust you’ll come to a less simple-minded conclusion after watching. Enjoy.
