Here is the wonderful thing about being a grown-up adult living in the US not incarcerated: We have choices!
If you have health and fitness goals that you are working towards, you have choices when you host or head out to a gathering of sports-watching pals. You may choose not to eat yourself into a state of meat-sweats, or a starchy coma, or a greasy-mouthed state of uncomfortable stomach gurgling. You don't have to feel bad tomorrow about over-doing it with lousy food today.
The occurrence of a football game does not revoke your power of choice.
So enjoy a few bites of the indulgent stuff and move on, keeping your health and fitness goals at front of mind. And please visit HERE for a reminder of how to eat at a buffet and enjoy yourself.
