Hi Omar, welcome to HCM.
I am glad you are concerned about your health. For your hieght, you need to be approximately 65-69 kilos. Also, you are just 16 and you will definitely have a weight gain in the next 3-4 years. Do not worry about it. Eat as much as possible and sleep enough. Also work out enough. Protein supplements
are not required unless you want to increase muscles a get into the fitness industry or so. Try eating healthy foods, lots of fluids, have frequent meals, avoid junk, include more dairy products and be happy.
