It's Monday. Perhaps you're lagging. Perhaps you're in need of a tasty caffeinated beverage to help you get through the rest of the day. If you're going to spring for a fancy coffee drink—it's Monday, and Mondays are the worst—order one that's foamy, and you may be able to skip your usual afternoon snack.
A new study tested three milk-based drinks: one that wasn't whipped (the control beverage), one with foam that dissipated within 30 minutes of consumption, and one with dense foam. For the four hours after consumption, subjects reported their hunger levels, and researchers measured the subjects' stomach content using an MRI.
The results? The dense-foam drink remained in the stomach longer than the less-dense foamy drink and the control. Appetite-wise, however, both foamy drinks kept hunger at bay equally well.
That's not to suggest that a 200-calorie latte is a diet food, or even something that's good for you, but it may be more satiating than, say, 200 calories of regular coffee loaded with half-and-half and pumpkin-flavored syrup.
