I'm a teenage boy 16 years old 5'4 and 108 lbs. I'm starting to change my lifestyle to becoming a healthy person. And I Really want to add weight cause I feel like I'm a very thin person and small. (In my country my height in this age is normal) but I feel like I'm only a Skin and Bone person.
Can you give me tips in gaining weight. Like foods that should I Eat, Routines must I do every morning (Like drinking a glass of water every waking up), Things that I Should avoid. Foods/Routines that can boost my immune system. (You know I'm a COMEDIAN type person. I love to laugh and I heard that LAUGHING can boost my immune system. Is that true? And some says that STRESS can lower your immune system cause you know. Even that I'm a funny guy. I sometimes think negative and feels like that I'm Depressed.) So again can STRESS and LAUGHING can lower/boost my immune system? I will wait for some reply and thank you for answers :)
PS: Sorry for my Grammar.
