Teenagers at the age of 16 are so conscious about their health and look. You may have noticed if a person is fat in his or her childhood he or she gets skinny during her teenage and vice versa for people being skinny in childhood.
It’s a long process of evolving. The human body can be changed as we want, focussing on skinny people it takes a lot to gain weight due to high metabolism.
Do the pro tip is if u can’t gain weight gain muscles. Workout gym for a year depending on your body type. Try to eat more carbs. Simplifying about what’s gaining is you have to cross your daily calorie limits according to your BMI. Yes, it’s working all you need is to be consistent. I have too experience it if you wanna see my IG handle is @drunk_sharma.
