What do skinny people really eat, when no one else is looking? Just a family, or better yet, a person alone?
As a nurse who sometimes visits people in their homes, I can tell you - some of them just don't eat that much.
And sometimes they skip meals -- fasting.
Or they just have a few bites of of something.
What do people of moderate size eat?
I had a heavy friend who called herself "O-BEAST" instead of obese. She ate what ever she wanted to eat. Like I once did.
Some people post actual pics of meals, or descriptions. Sometimes, I don't think anyone could just eat what they eat, and live.
We probably don't need NEARLY as much food as we think!
