Skinny People Rarely Diet

The purpose of the Global Healthy Weight Registry, essentially, is to share the secrets of not getting fat with the rest of us. It’s just another way that scientists are trying, mostly in vain, to help curb the obesity epidemic.

The Food and Brand Lab recently released another ream of data from the 147 registry participants. Some of their answers are just as frustratingly practical and responsible as you’d expect: Half weighed themselves at least weekly, all but 4 percent eat breakfast, and all but 10 percent of them exercise. Forty-two percent work out five or more times per week. The majority always eat vegetables at dinner and say chicken is their “favorite meat.”

One explanation could be good genes. The healthy-weight registrants might never diet because, being naturally thin, they never need to. Still, that wouldn’t explain why they do all those other things—the exercising, the salad lunches, all that poultry. Clearly, they are putting some effort into their figures.

Instead, Brian Wansink, director of the Food and Brand Lab, chalks it up to the fact that many of the registrants used “non-restrictive” strategies, like listening to hunger cues, cooking at home rather than eating out, and eating quality, non-processed foods.

“Most slim people don’t employ restrictive diets or intense health regimes to stay at a healthy weight,” he said in a statement. “Instead, they practice easy habits like not skipping breakfast, and listening to inner cues.”

Of course, only eating when you’re hungry and passing up pizza for homemade soup is its own kind of diet. (Indeed, according to the release, 92 percent of the registrants reported being “conscious of what they ate.” )

The reason many people diet is for the structure: Maybe they don’t have time to cook vegetables for dinner, or don’t know how, or they just like having a piece of cake after an already too-big meal. Those people are looking for some strict food rules to follow temporarily, and they find them in the form of a diet. But the way the registry participants maintain their svelte weights (136 pounds, on average) is by following some slightly less strict food rules for pretty much their entire lives. It explains why they’re thin, yes, but it’s not exactly the easy way out.
