Finding a Balance of Food and Activity
A healthy lifestyle includes good nutrition and adequate physical activity. If you need to gain or lose weight, consider changing your dietary pattern and physical activity level to achieve your goal.
Food and Nutrition
Counting calories all the time is not necessary, but in the beginning, it may help to determine how many calories are in the foods and drinks you consume regularly. See MyPlate Plan to determine how many calories a day you need to maintain your current weight based on your age, sex, height, weight, and physical activity level. Then click on the results to see recommended daily amounts fruits, vegetables, protein, dairy, and grains for adequate nutrition at your calorie level.
To learn how many calories you are taking in, write down the foods you eat and the beverages you drink, plus the calories they have, each day. Check the nutrition facts label for serving sizes and number of calories, and consider portion size.
A food and beverage diary [PDF-126KB] will help you become more aware of what you are consuming. Also, begin writing down your physical activity each day [PDF-571KB] and the length of time you do it.

Here are simple paper and pencil tools to assist you:
Physical Activity
How much physical activity you need depends mostly on your age.
- Preschool-aged children (ages 3 through 5 years) should be physically active throughout the day for growth and development.
- Children and adolescents (ages 6 through 17 years) need 60 minutes or more of moderate-to-vigorous intensity physical activity each day. Children and adolescents need aerobic, muscle-strengthening, and bone-strengthening activities.
- Pregnant or postpartum women, with their doctor’s approval, should do at least 150 minutes of moderate-intensity aerobic physical activity per week, such as brisk walking. It is best to spread this activity throughout the week, such as 30 minutes a day, five days a week.
- Adults need 150 minutes of physical activity each week, including aerobic activity and muscle-strengthening activity. This can be 30 minutes a day, five days a week.
- Adults age 65 and older need at least 150 minutes a week of moderate intensity activity such as brisk walking, at least two days a week of activities that strengthen muscles, and activities to improve balance such as standing on one foot.
