You may want to ask your doctor for advice the next time you have a check-up. In some cases, people who have a hard time gaining weight actually have a thyroid hormone imbalance, and is corrected with medication. I had this problem, but you may not. Try drinking Boost or Ensure meal replacement shakes, they should help you increase calories and weight in a healthy manner & lifting weights can help build muscle mass.
Good luck.
eat heaps of food, man
cadburies, choclates,chocolate cookies, ice creams.
I was too thin most of my life. I wanted to gain weight, in high School. So, I hung around voluptuously full figured people, and copied what they ate.
I added a chocolate milk shake, to every lunch. It worked. It was a gradual process. Pasta packs one weight too.
Now I have to be careful, or I gain.
drink supplements and go to the gym
more proteins !!
