I want to know if my weight gain is healthy?!

Question: ok, im 15 and 1/2. And im 5'7'' and in early Dec. i weighed 115 and i weighed myself today when i was at a friends house and im just at 140. Im kinda chunky, but i want to know if i need to loose some weight, or eat healthier. Right now i kinda just eat what i want and eat fast food like two or three times a week. If i do need to loose weight or eat better what would you suggest?
