What Makes Me the Weight I Am
There’s no easy answer to this question. Your genetic makeup, the physical traits that get passed down to you from your parents, plays a big part in determining your size and weight. (46) But if your parents are smaller than average, you may want to rethink that professional basketball career!
The same goes for your body type. Have you ever heard someone say a person is "big boned" It’s a way of saying the person has a large frame, or skeleton. Big bones usually weigh more than small bones. (47)
Like your height or body type, your genes have a lot to say about what your weight will be. But that’s only part of the story. Being overweight can run in someone’s family, but it may not be because of their genes. (48) And even though some kids gain weight more easily than others, when they eat right and exercise, most kids can be a healthy and happy weight that’s right for them. It’s true — the way you live can change the way you look.
How much you weigh is a balance between the calories you eat and the calories you use. (49) If you spend your free time watching TV, your body won’t use as many calories as it would if you played basketball, skated, or went for a walk. If you are in balance, your weight will stay right for you as you grow. But if you eat more and exercise less, you may become overweight. (50)
A That’s why it’s possible for two kids with the same height, but different weights, to both be the right weight.
B If you eat more calories than your body needs to use, you will gain too much weight.
C Poor eating and exercise habits also run in families and this may be the reason the members of a family are overweight.
D However, many overweight people have difficulty reaching their healthy body weight.
E On file other hand, if you eat less and exercise more, you may lose weight8.
F If both your parents are tall, there is a good chance you’ll be tall.
