portion size

Here's a simple article about how portion size has been distorted over the years in the American diet: How Portion Size Adds Up

...if you feel like you don't know how much is too much, or it seems like you don't overeat even if you do, this may help. Our internal scales have been affected by the cultural supersizing effect so that when we make or are served a normal portion of something, it seems like it's not enough. Or when we're served multiple portions-worth of food, we eat more because it's right there in front of us...

It can be especially challenging to fight against a century of cultural diet manipulation... so if you feel sometimes like you're crazy, fighting an un-winnable battle, don't give up. You're not crazy, the battle is not really a fight but a commitment to a better personal future. And if you think you're going to starve if you have to live by "normal" portion sizes, just know that you're not... it takes some working into, takes some patience to let your body adjust down into more healthy parameters, but in the end, as the cliche goes, it will be worth it, and you are worth it.
