Hello!
I believe that the factors of Jason sticking to his healthy-eating plan are food availability and dietary guidelines. I believe that if fast food wasn't available to him as often then he'll gradually lose that temptation of cheating on his diets and dietary guidelines might help him stay on track on his diet and even help him make a healthier version of what he was tempted to eat before.
I hope this helps!

A) Sexual contact; Human papilloma virus
Good luck! (:
The junk food is the poor nutritional choice
I think the best thing to do is not to touch it and contact a dental office so will be ok
It traps germs so they do not get into the body
