Great. First of all,you are very skinny,not kinda..so lets start with that😁. Then,if you are skinny thats bcuz your metabolism is faster than a normal person. You could gain some in the future when your metabolism starts to drop ,but if you want to gain now EAT MORE CALORIES THAN YOU BURN! Voilah. But tracking your foods calories might sound tiring but its worth it. 2, you can start working out and gain a quality muscle while tracking your food's calories. I would recommend workin out tho.
