I'm underweight and could use some tips.

[QUOTE="chessmaster1989"]Go eat at McDonalds for lunch and dinner every day for a couple of weeks.ieatnoobs18

learn to food. also, workout.

I weigh a good bit for my height ( its the muscley shoulders) and to gain weight, primarily raw muscle, I would:

Eat eggs for breakfast, toast.

Eat a peanut Butter and banana sandwich with wheat bread for lunch, and eat a healthy protein filled dinner. (Perfect for working out carbs, potassium, protein,)

But, you have to workout, or you will harm yourself, so do calisthenics and lift weights, or if your poor, rocks. Another idea is to fill large urns with varying levels of rice, and work out with them. Seriously, these are simple, cheap ideas, that should work. I am not a doctor, but I am quite observant. One of the strongest and heaviest guys I know, works out and eats a whole lot of protein. Take it or leave it.

Yeah just force yourself to hit the gym for at least a good half hour every other day (everyday would be even better). The eating would come naturally if you exercise that much. I used to weight 150 lbs at 6 feet, then decided to hit the gym everyday for an hour and viola, my weight shot all the way up to 183 lbs. I looked leaner but the muscle actually made me weight more.
