How do you beat the convienient food.

Wondering how everyone avoids the food that doesn’t so much taste better but is just easier to get and go?
things like fast food or snacks at the gas station.
The later in the day I’m hungry but just don’t have it in me to cook but McDonalds is only a mile away type times.

In all honesty these are the things that have kept me from doing everything I’ve wanted diet wise.
