Weight Management - What Affects Your Weight?
Genetic makeup—what you inherit—plays the biggest role
When we say "genetic makeup," we're talking about everything you
inherited from your ancestors, from the color of your eyes or the shape of your
toes to the way your brain works and the way your body stores fat.

the rate at which your body uses energy (calories) at rest. Some people are
born with higher basic metabolic rates than others. These people naturally burn
more calories than the rest of us.
- Your fat distribution.
- Some people have slim legs, some have
heavy legs. You can't change where your body stores fat.
- Typically, men store fat in the abdomen while women store more in the hips and thighs. As women age, more fat is stored in the abdomen.
Nutrition—what and how you eat—also affects your weight
The average American meal contains too many
calories. It also contains too much saturated fat,
cholesterol, animal protein, salt, alcohol, and sugar.
It can be hard to make healthy food choices:
- Emotions and easy access to fast foods and
snacks are among the many
things that influence our food choices today.
- Lack of time leads many people to eat on an irregular schedule or
skip meals. People who do that have more trouble staying at a healthy weight
than people who eat regular meals.
- Sometimes a food that seems like
a healthier choice may not be. A low-fat cookie may have less fat, but usually
it is high in sugar and has the same number of calories as a regular cookie.
Potato chips that are "cholesterol-free" may still be high in fat and calories.
