Unfortunately, there is no way of putting inches on your frame instantly. Growing taller is mostly about genetics. Between 60% and 80% of your height is determined by the DNA that your parents passed down to you, whereas about 20% to 40% of your growth is influenced by your own environment.This means your diet, your health, how much you exercise, and how much sleep you get.
Until your growth plates (the areas where your bones grow) close, you will keep growing. A good diet, healthy exercise, and lots of sleep can help you get taller in this period than you would otherwise.
For most people, however, growth plates close in their early twenties, and after that, they are not going to gain any inches naturally. Women typically stop growing around age 18 while men may stop around age 20.
Eat right. A balanced diet filled with plenty of healthy nutrients will help you to grow strong and healthy and reach your full height. That means staying away from the cakes, sodas,
and pizzas and reaching for the salads, whole grains, and fish. If you are having trouble motivating yourself to eat these foods, search for different recipes and look for combinations of food that you find appealing.
