The Claim

Tree nut consumption in US adults is associated with a 1.42 cm reduction in waist circumference for every 26.6 g/day increase in intake, independent of age, income, education, and lifestyle factors.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

In US adults, eating more tree nuts is linked to a smaller waist size, with each additional 26.6 grams per day associated with a 1.42 cm reduction in waist circumference, after accounting for age, income, education, and lifestyle.

See the scientific wording

Tree nut consumption in US adults is associated with a 1.42 cm lower waist circumference for every 26.6 g/day increase in intake (from 7.09 g to 33.7 g), independent of age, income, education, and lifestyle factors, suggesting a dose-dependent association with reduced central adiposity.

Why this might work

Eating tree nuts increases the body's ability to burn fat for energy and decreases the amount of fat stored around the waist.

    People who ate more tree nuts, like almonds or walnuts, tended to have smaller waistlines—even when accounting for how much they exercised or their income. The more nuts they ate, the smaller their waist got.
