The Claim
In U.S. adults, tree nut consumption at an average intake level of 33.7 g/d is associated with a 1.42 cm lower waist circumference compared to a low intake level of 7.09 g/d, after adjustment for lifestyle factors.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
U.S. adults who eat about 33.7 grams of tree nuts per day have, on average, 1.42 centimeters less waist circumference than those who eat about 7.09 grams per day, even when accounting for other lifestyle habits.
See the scientific wording
In U.S. adults, tree nut consumption is associated with a 1.42 cm lower waist circumference between average (33.7 g/d) and low threshold (7.09 g/d) intake levels, even after adjusting for lifestyle factors, suggesting a modest but consistent relationship between tree nut intake and reduced central adiposity.
Eating tree nuts increases the body's ability to burn fat for energy and reduces the amount of fat stored in the liver and around the abdomen, leading to a smaller waist size.
What the research says
1 studyPeople who eat about an ounce of tree nuts a day tend to have slightly smaller waists than those who eat just a tiny bit, even when you account for how much they exercise or eat overall — and this was found in a large, reliable U.S. study.
