How to put on weight for a thin teenager?

Good day.

I advise you to study the most important points that are important for gaining muscle mass:

1. Nutrition - Without a good diet, you won't be able to gain muscle mass

2. Sleep - good sleep is essential for the growth of not only muscles, but the whole body.

3. Workout - yes, workout comes last, because without sleep and nutrition, workouts do not make any sense.

It seems to me that you are a young man (for girls without exception dream of losing weight, even if they don’t need it at all), have recently gone in for sports and want to gain muscle mass as soon as possible. Did you guess right? I think that homemade methods (like "eat more pies") do not help, since you are writing here. But in any case, success really depends a lot on nutrition. Read on the Internet for information on daily requirements - there are online calculators and ready-made tables for different ages and different levels of physical activity. You need a healthy and balanced diet - nobody has canceled BJU yet. Lean on cereals, quality meat and dairy products (yes, vegetarians are more difficult). But only for God's sake, do not try to artificially accelerate the process of muscle growth due to dubious drugs and dietary supplements - you can cause irreparable harm to the growing body and get not the result you dreamed of! And of course, sports loads should be regular and full. Ideally, you need a competent trainer who will direct you on the right path even in the rocking chair (without injuries and overloads, but with the benefit of the body), and will prompt you with nutrition. And it would be nice to consult a nutritionist. In general, a well-thought-out diet and sports - and after a while you will see in the mirror not a thin, awkward teenager, but an athletic, pumped-up young man. Good luck!
