Some here might disagree but I think restaurant portions are way too big. Even when I was in the hospital, laying in bed all day,not burning hardly any calories and the food portions were impossible.
I was raised to finish what's on your plate. There I couldn't. Finally I found out they did have senior portions. That was a little better if I crossed off some items.
There are restaurants in town I won't go to because of size.
Somewhere in my head I always think not to be stuffed with food as you never know when you might be in combat.
When younger I ate a lot but at sometime I quit and I'm still a little over based on height but maybe 10#.
