200 calories is usually the standard guideline for a snack, but it can be quite tricky finding foods that meet this guideline. (Especially healthy foods!) Knowing how many calories one serving yields can be confusing as well, which is why it is important to have a better sense of portion sizes.

Thankfully, WiseGeek created a helpful series of photos showing exactly what 200 calories looks like for different foods. They also organized the foods in order from low-calorie to high-calorie density. The list can be a helpful tool in helping you better choose your next snack or meal!
