Recommended Answer:

You should never eat junk food to gain good weight. You need good proteins such as nuts, egg whites and such. Though your age might make it tough to gain weight. You may still have high metabolic rate. If you want exercises to bulk up weight lifting is best. Squats, bench, military press, pull ups and such.

• Eat more than 3600 calories a day. Or do the supersize me challenge.
• Try and up your calorie intake through adding a few healthy snacks, such as apples and nuts, in between your meals. Or, try eating more healthy fats such as avocado, with salad. Sweet potatos are also very nutritious and filling (better than regular potatoes) and you could add these to recipes as well. Try some complex carb/protein snacks like lentils or barley added to regular soups. Eat lesser processed cheese on top of some mealsDon't go for high intensity cardio. Just about 30-40 minutes moderate on a treadmill should do it nicely for you.
