I like your visualising idea.
I cook for 2 guys at present that are NOT into diet foods.
I can get the plain meal past them. It's mostly when he cooks that I have the most trouble.
He works for a big pizza and sports place and was a truck stop cook for years.
The things I saw go into food-YIKES.
He doesn't put a whole stick of butter in a couple quarts of green beans anymore-I flipped right away on that one.
He doesn't drain the meat grease off of beans or if he's making his rare sausage biscuts and gravy-the amount of flour he dumps in that-you can feel your arteries closing.
Yes, I try to do most of it.
If Cobeach can eat before and right after work, she may be able to pick out slimming food choices from their menu or very small portions of what they are eating.
Spread her food out on the plate to look like more than is actually there. I find it tricks my mind if I eat it slowly.
