The following can be adopted to stay healthy:
Focus on a healthy diet, not dieting. Dieting implies deprivation. Instead, you need to adopt lasting ways to meet the needs of your changing body.
Learn to tune in to your body’s cues. Paying attention to what you feel can help you learn to eat when you are hungry and stop when you are full.
Increase exercise and movement. Add short periods of activity to your day.
Make small changes in your diet, like substituting a whole-grain cereal for processed breakfast cereal or tofu or beans for red meat in a main dish.
Don’t let your weight determine your self-esteem. The number on the scale tells you one thing: how much you weigh. It says nothing about your value as a person or your chances of happiness.
Aim for healthy habits—choosing healthy foods and exercising regularly—and let your weight stabilize where it will.
Learn to accept and even appreciate your body. Body shape is not as changeable as we are led to believe. Genetics plays a strong role: most of us will never look like supermodels no matter what we eat or how much we exercise.
Advocate for changes in your food system. Join your local food cooperative. Become involved in community-supported agriculture (CSA). Get your school to substitute healthy foods for the junk food in the vending machines. Educate yourself and your community about nutrition and the politics of food.
