Surprising news: we may be overestimating how many calories we eat. The New York Times reports that, according to nutrition experts, healthy eaters may be consuming several hundred calories fewer [1] than they think.

The problem lies in the way that calories are counted, which is based on a system from the 1800s that fails to take into account how many calories are lost when we digest foods that are harder to break down, especially those that contain a lot of protein or fiber, like nuts. If your healthy snacking habits include a handful of nuts (and there are many weight-loss reasons [2] to eat them), here's the good news: one serving of 23 almonds is actually 120 calories instead of 160 calories as they are currently labeled — 40 fewer calories than previously thought. While these calorie savings shouldn't give you license to grab a second helping all the time, if you're trying to lose weight by eating right and counting calories, small savings like this can help you reach your goals.
