I stay away from fast food as much as I can.... unless if I'm
really desperate or in a rush and there's nothing better to
eat.
Even then, I am selective about what I eat. KFC Roasta Burger,
for instance, is much less damaging than the Double Down if you ask
them to not put the mayo.
Likewise, a baked potato and a small chili at Wendy's isn't
gonna hurt you much.
Just keep the eating of fast food to a minimum, and make better
choices if you have to eat at such places.
