Passage Summary: Even though nuts are packed with calories and eating lots of calories usually makes people gain weight, people who eat nuts often are actually thinner than those who don't.

Reasoning: Nuts have high caloric density, and high caloric intake usually leads to weight gain, yet regular nut consumption correlates with lower weight.

Analysis: We have a classic 'calorie math' conflict here. On one hand, nuts are calorie-dense, which should logically lead to weight gain. On the other hand, the data shows nut eaters are actually less likely to be overweight. To resolve this, look for an answer that explains why the calories in nuts don't result in the expected weight gain—perhaps they make you feel fuller so you eat less of other things, or maybe the body doesn't absorb all those calories. It's a classic case of human biology being more complex than simple addition.
