Is it normal i cant get fat even if i try
I am really skinny , 20 years old , 55 kg , 178 cm tall , i try my best to get fatter but it wont work ,i eat x3 what my fat friends eat and i dont add up 1 kg this is insane , doctor gave me some vitamins and proteins but they are useless , 55 kg wont go up but goes down if i skip a meal i cant believe it , and no body else does.
Btw i can eat 4 burger + drinks at lunch and not feel stuffed
And also i dont even play sports
