Food 3

Not too much.

Yep don't overeat.

Hunger is not fatal. At least not in the US where food is available on every corner. Mal nutrition can be fatal.

Do you realize that overeating can kill you? I don't mean in the long term by making you fat. But (always a but) but in the short term. Stuffing yourself will make your stomach full, increases how long digestion takes, can make your blood sugars malfunction, (pancreas), overworks you liver (fat), taxes you gall bladder, if its been removed your liver also takes over some of the gall bladders previous chores, makes your brain foggy, and makes your heart work overtime. Puts pressure on lungs and diaphragm.

A good guide is that 8 inch plate, 1/2 vegetables, 1/4 protein, 1/4 carbs.

Use portion sizes. I know it seems so elementary. Check the labels. But we really do have portion distortion. We see super-size everywhere we look.
I don't know how many times recently I have said or heard said, what! that is a portion? nobody would eat that little amount.
But it is what it is, if you eat double or triple that amount, your are eating double or triple the servings. It doesn't matter what your THINK, it is what it is.
You could eat 1/2 of today's normal portions and still be getting more than twice the calories you need to maintain your weight. More than 5 times what you need to be healthy.
