If you're watching what you eat, then you know all about portion sizes and the tendency to have eyes bigger than your calorie limit. Diet-blog has rounded up a great list of sites to help you more visual dieters eyeball your portions. Whether you're looking for a light snack (around 100 calories) or a more substantial 200-300 calorie filler-upper, these photo collections can help you choose and portion wisely.

These photos also serve as a reminder that, when it comes to calories, you get bang for your calorie buck when you stick to fruits and vegetables. That tiny piece of chocolate may be calling your name, but for the same number of calories you can eat an entire bowl of strawberries and extra nutrition as well.

As do many people, I hate wasting food. So, although it's a poor excuse for overeating, the fact there's "just a little left in the pan and it won't really keep" is one of my most common pitfalls when it comes to portion control. Portion sizes in this country are out of control, there's no doubt about that, and could it be that one contributing reason is people's aversion to wasting food? It's a small reason probably, but I bet it's part of it.

Not to downplay the challenges of cooking for a large family, but having extra food sitting around isn't usually one of them. But for single people, or even some couples, it's another story altogether. Most recipes don't make just 1 or 2 servings, and most foods in the store don't come packaged in smaller more convenient amounts, or if they do they're much more expensive and hardly make sense.
