Eating nuts has been associated with weight loss.

A recent study found that people extract 21% fewer calories from walnuts than what is listed on the label.

A one ounce (28 gram) serving of walnuts provides 146 calories rather than 185 calories as previously thought.

This helps to explain why eating tree nuts are associated with weight loss.
