The Claim

In US adults aged 20 and older, consuming at least 7.09 grams of tree nuts per day is associated with a 9 percentage point lower prevalence of obesity and a 1.42 cm lower waist circumference compared to nonconsumers, after adjustment for age, income, education, and lifestyle factors.

In plain English

US adults who eat at least 7.09 grams of tree nuts daily have a 9 percentage point lower rate of obesity and 1.42 cm smaller waist circumference than those who do not eat tree nuts, even when accounting for age, income, education, and lifestyle.

See the scientific wording

In US adults aged 20 and older, consuming at least 7.09 grams of tree nuts per day is associated with a 9 percentage point lower prevalence of obesity (31% vs. 40%) and a 1.42 cm lower waist circumference compared to nonconsumers, even after adjusting for age, income, education, and lifestyle factors, suggesting a consistent link between modest tree nut intake and reduced central adiposity.

Why this might work

Eating tree nuts triggers stronger fullness signals in the brain, causes the body to absorb fewer calories from food, and increases the amount of fat passed out in stool. This leads to less fat stored around the waist.

    People in the U.S. who eat at least a quarter-ounce of tree nuts every day tend to have smaller waistlines and are less likely to be obese than those who don’t eat nuts — even when you account for differences in how old they are, how much money they make, or how active they are.
