People who pay less attention to their hunger and fullness signals tend to have higher body mass index, larger waist size, and higher waist-to-hip ratios, suggesting that this lack of awareness may increase obesity risk even when diet quality is accounted for.

We analyzed the available evidence and found that lower mindful eating scores are consistently linked to higher body mass index and larger waist circumference in young adults. The evidence we’ve reviewed so far includes 48 studies or assertions that support this connection, with none that contradict it [1]. People who score lower on mindful eating measures tend to pay less attention to their hunger and fullness cues — meaning they may eat even when not physically hungry, or continue eating past the point of comfort. This pattern was associated with higher body weight and more abdominal fat, even when researchers accounted for how healthy someone’s diet was overall. In other words, the link between low mindful eating and higher BMI or waist size doesn’t seem to be just about what people eat, but also how they eat. We don’t know if this relationship is caused by other factors like stress, sleep, or lifestyle habits, and we can’t say whether improving mindful eating would change body measurements. But the pattern across all 48 observations suggests a consistent association. What this means for young adults is that tuning into bodily signals during meals — noticing when you’re truly hungry or full — might be one piece of a larger picture when it comes to managing weight. It’s not about strict dieting, but about becoming more aware of how your body feels while eating.
