How would I gain weight?

Okay firstly you're amazing for acknowledging the fact that you're skinny.

Junk food= unhealthy weight gain. What I mean is that you gain body fat, yes, but it also risks clogging up of arteries, breakouts, increased feeling of fatigue etc. So don't go rushing for Macs just yet. Start by protein. Think of yourself as a bodybuilder. Eggs, chicken, fish...try to go for white meat instead of red meat as they are healthier. If you want to snack or your body is craving oily foods, try pretzels. It prevents you from feeling bloated(the feeling you get after an oily meal) and yoghurt is fine too. Also incorporate some wholegrains into your diet-bread, rice, pasta that sort of thing. Do remb to exercise too-just focus on strength training instead of more cardio workouts to build on body mass. Hope this helps!

p.s. If you're a vegetarian, I'll recommend going to a dietitian.

By increasing your daily food intake will sure put some weight on you..but you cant decide where...you could gain weight all over...but on the other hand, you might just end up gaining weight where you don't want..so exercising is key..to gain weight just just eat a high carbohydrate diet..Increase your daily calorie intake by around 500...and drink plenty of water

eat more calories then what you burn, but workout the areas that you DONT want the fat going too (such as your tummie)

if you excercise wear a bedopmeter thingy ma jigger.

see how many calories you burn a day

then eat more than that haha
