These results shouldn't be confused with previous knowledge though, it's still true that it takes the body 20 minutes to register satiety, which means that eating quickly could lead you to overeat — or at least eat more than your body needs. But what the study did discover is that even though people said they felt fuller after a longer meal, they didn't actually behave that way when presented with more food.
Snack cravings or not, eating slowly has other advantages, too. Fast eaters are also at risk for acid reflux and indigestion (so check out some tips for slowing down if you're an unintentional fast eater). The moral of the study: the volume and caloric makeup of the food you eat will determine how full you feel, regardless of how fast you eat it; watch your portions and choose healthy snacks when you do eat between meals.
