Thank you for responses.
At home, all is good with good options.

Yesterday, I was away from home.

Started the day low energy, tired.
After working away from home,
my BGL was getting low,
I was super hungry and had nothing to divert
for energy on hand in my car.

So, I needed calories and went to a bad food restaurant.
Mostly, the bad was pizza crust with carbs. Rest of the
salty greasy "meats" and bad cheese were probably low carb,
but I did not want to be there and have eaten it.

Later, after I wrote this post, my body became inflamed/inflamatory'd.

The positive is that just getting inflamed is a good lesson learned.

Plus, everyone's advice to "be prepared" in my car is very good.
I'll have to find food that can stay in my car,
even if the summer heat is hot in the car.
Will review peanut butter and cheese sticks.
What other low carb foods can stay in your hot car?
