You've heard the general rules, meat portions should be matchbox sized, etc. However, sometimes it can be difficult to remember what a matchbox actually looks like, particularly when you're staring down a basket full of buffalo wings. The next time you're in need of a little resolve, look no further than the back of your hand (or the front or heck, even just your fingers).

This handy infographic from Guard Your Health offers a quick reminder that your butter pat should be no larger than the size of your fingertip, that your protein should be roughly the size of your palm, and that your carbs should only fit the size of your clenched fist.

Check out the full infographic below for a few more tips, or just some lovely hand porn (you know, if you're into that).
