I really watch my diet and exercise.
I still go to "All you can eat" buffets since I can be choosy about what I get, and get it quickly.
I eat one plate of salad. One plate of hot food. Not heaping.
And I watch the carbs. Maybe 1 spoonful of desert just for a treat.
For me, it's a quick meal with convenience. Not a reason to eat like a pig.
