What do half a spoon of peanut butter, a miniscule slice of apple pie and 41g of Cadbury's Creme Eggs have in common? They all contain 200 calories.

If you're watching your weight, you're probably well used to checking the back of wrappers for nutritional information. But if you're eating unpackaged food, making something from scratch or just aren't mathematically minded, it can be difficult to figure our just how many calories you're consuming per portion.

A new app called Calorific aims to simplify healthy eating by showing you just how much food you need to eat to take in 200 calories. While it doesn't specify how food is cooked (eg. fried egg versus scrambled egg), it does give you a pretty solid idea of how much food is too much when you're counting calories.

So you'll now just how much cheddar to put in your lunchtime sandwich, or how many restaurant breadsticks are enough:

And next time you're making a bacon sarnie, you can keep these pictures in mind:

The apps creator, Aterm Petakov, says Calorific will hopefully re-educate people about the food they're consuming. "The truth is, most people eat junk and know that it's junk," he said. "What they need is a way to be held accountable for those choices and change them over time."

Sounds good to us!
