Hey I just need to know is it bad to be a junk food junkie I am about 5'7 and weigh 98-102lbs. I eat all the time normal food and junk food. But when I eat my normal meals every day I get full real quick but I cacn continue to eat junk food. Is it me? I have been to the doctor I am perfectly healthy with nothing wrong. Is it just a mind setting. Also, I drink tons of big red is the "red" bad for my body?
