Why is it easier for some people to lose weight?

In a recent study, researchers gave participants extra calories and then measured what happened when they tried to lose the extra weight.

Researchers fed 35 young adults (mostly men) 40 percent more calories than they needed for two months. Each participant got 1,160 extra calories a day, on average.

The average participant gained 17 pounds (though weight gain ranged from 5 to 24 pounds). Six months later, they had, on average, lost only 9 pounds of their excess weight.

Those who burned the most calories for their size (“spendthrifts”) while they were being overfed lost more weight later than those who burned fewer calories (“thrifty” types).

What to do: Don’t assume you can overeat and lose the weight later. “Human metabolism evolved to protect against calorie deprivation, not so much against calorie excess,” wrote the authors.
