Parents and caregivers want their children to feel their best. This often means having healthy habits in place for fitness and good nutrition.  However, about 20% of teens in the US are obese and the trend shows that children are becoming heavier at a younger age. Of this age group, Hispanic and Black teens are at an even higher risk.  In addition, it has been shown that 80% of overweight teens become obese adults.  Because children learn many of their habits from their families at an early age, parent and family support can go a long way in setting a teen up for success in the areas of exercise and diet.

Physical Activity 

Physical fitness is one of the best ways to feel good, support mental health and stay well.  However, 1 out of every 10 teenagers does not get enough exercise.  Part of this is due to spending more time on screens and less time outdoors than generations in the past.  Other factors include, less physical activity during school breaks and more time sitting down to study than they did when they were younger.

A typical teen should be getting at least 60 minutes of moderate to vigorous exercise per day.

Ideally, this would include aerobic (like running, dancing, skateboarding and mountain biking), bone-strengthening and muscle building activities. Since kids at this age really want to spend a lot of time with friends, finding an activity they can do together or with a team may help to foster this habit.

Teens with health conditions or disabilities should not be excluded from sports and other physical activity. There are ways to adapt fitness exercises so that everyone can be involved.  It will be important to work with the school physical education teacher as well as a primary health care provider to find out what is and is not safe for each child. 

Nutrition and Hydration

A well-balanced diet and drinking enough water also contribute greatly to a teen’s well-being.  Sometimes the only options of interest to teens are sugary drinks and fast food.  Some believe that teens can eat whatever they want because they are young and their bodies will burn it off.  While this might be the case for some, the CDC says that over 20% of teens 12-19 are considered obese. Not only that, but teens are at an age where nourishment is vital to their body and brain development, and establishing good eating habits at this stage is important. Like exercise, what a teen decides to eat can also affect their mental health, energy levels, skin, and hormones.

The average calorie intake for teens is about 2,200 for girls and 2,800 for boys.  This may vary depending on how active they are and their height and weight.  Ideally, these calories come from whole grains, vegetables, fruits, lean and high-quality protein, good dairy products, nuts, and seeds. 

Below is a chart from the Mayo Clinic that lists what a teenager’s daily intake should be and how much.


For Girls

1,800 – 2,400

For Boys

2,000 – 3,200


(eggs, fish, good quality meats, beans)

For Girls

5 – 6.5 ounces

For Boys

5.5 – 7 ounces


(apples, bananas, berries, kiwi, mango, etc)

For Girls

1.5 – 2 cups

For Boys

2 – 2.5 cups


(green beans, sweet potato, broccoli, zucchini, lettuce, cauliflower, etc)

For Girls

2.5 – 3 cups

For Boys

2.5 – 4 cups


(rice, quinoa, etc)

For Girls

6 – 8 ounces

For Boys

6 – 10 ounces


(yogurt, cheese, cottage cheese, milk, etc)

For Girls

3 cups

For Boys

3 cups


In addition to nutrients, teens need to stay hydrated so that their digestion can work properly.  This means they should consume between 2-3 quarts of water per day.


Kids go through a lot of changes during the teenage years, some of which are hormonal.  This can lead to increased sweating, facial hair, body odor and skin issues. It is a good time for them to learn some of the basics of self-care and good hygiene so they can feel clean and confident at school and with their friends. 

The foundation for good hygiene is clean clothes and a clean body.  This includes showering regularly, brushing and flossing every day, wearing deodorant when needed and making sure clothes and sheets are washed on a regular basis.  For teens who also do sports, they should clean their uniforms after practice and games/meets. 

Why it Matters

As mentioned above, lack of exercise and poor nutrition can result in health issues like obesity and type 2 diabetes, both of which can create other health problems. They can also lead to or exacerbate mental health problems like anxiety and depression.  Finding ways to get your child moving and also feeding them nutritious foods will go a long way in establishing healthy habits and well-being.

Treats and processed foods should be saved for special occasions and only eaten in moderation.  If possible, also have your teen avoid sugary drinks even after they have done sports or vigorous exercise.  The most important and useful liquid they can consume is water. Two to three quarts of water is ideal.

Signs that your teen may have a poor diet include, but are not limited to:

  • Being overweight or underweight
  • Irregular or poor elimination (bowel movements)
  • Excessive tiredness
  • Poor growth

Connect & Communicate:

Start the Conversation:

You can start a conversation with your teen by reviewing the checklist above and highlighting and congratulating them on the things you notice they are already doing.  Before telling them what you feel they should do next, ask them how they feel physically and mentally and if there are some things they want to try. 

It is important to remember that developing a new habit takes time, so having them choose 1 or 2 things they want to improve is enough. Once those have become established habits, encourage them to select more. In addition to helping them develop healthy exercise habits, find ways to stay fit as a family.

If you are concerned about your teen’s weight, don’t make that the topic of conversation. Instead, focus on the importance of living a healthy lifestyle.  Connect exercise and nutrition to health and well-being, not weight, as this could potentially lead to unhealthy habits and even eating disorders. You can also approach them by sharing the challenges and successes you or another family member has had in choosing a healthier lifestyle.  

In addition to talking to your teen about healthy lifestyles, there are ways to motivate kids to be active and to eat well.  Read through the ideas and think about which ones may be best suited for you, your teen, and your family.

  • Be a role model by exercising, eating well, and talking about how and why your family values fitness and nutrition.
  • Exercise together as a family or do an activity that your teen enjoys.
  • Have equipment out in the house, garage, or yard that encourages physical activity.
  • Spend time in community spaces that have fields and courts to play in.
  • Remind them that all physical fitness counts and help them find one they enjoy.
  • If they prefer to stay home, help time find online classes or videos.
  • Involve your teen in planning meals, buying food, and helping to prepare meals.  Give them some choice and autonomy on what healthy foods they choose.
  • Put fruits and vegetables out on the counter instead of junk food.


Here are some other activities you can do to increase your teen’s awareness around fitness and nutrition and to help them become more active and healthy.

  • Watch the documentaries Fed Up, Bite-Size, or Sugar Coated and discuss the theme with your teen.
  • Build exercise into some of their screen time.  For example, do sit-ups or push-ups during a commercial.
  • Help them find friends who enjoy the same activities and get them to organize regular training or practice.
  • Find healthy recipes online and have your child read through them, get the ingredients and cook for the family.
  • Allow each member of the family to decide on a physical activity they want to do each week and the whole family participates.

Contact & Collaborate:

You can work with your school to find sports or extracurricular activities that your teen may enjoy.  The school counselor or nurse may also have some resources to help with nutrition and exercise.  Some teens may overdo it because of the pressure to perform.  For example, if they are involved in wrestling, dance or gymnastics, there may be a weight they need to maintain.  This may cause them to push themselves too far, so make sure that you are in communication with coaches and doctors to make sure what your child is doing is safe.

If you are unsure or concerned about your teen’s health, weight or diet, contact their primary care doctor.  They may be able to refer you to a dietician, help create a fitness plan or provide additional resources and support. 

  • Find classes at the local YMCA, church, Boys and Girls club or community center
  • Encourage them to do sports or activities at school that require movement.  They could be competitive or something like running

Diversity, Equity, and Inclusion

The terms diversity, equity, and inclusion have become household words. These topics have been highlighted in recent times by nationwide race-related protests and social unrest.

Family Relationships and Wellness

Children feel secure and loved when they have strong and positive family relationships. Positive family relationships help families resolve conflict, work as a team and enjoy each other’s company. Positive family relationships are built on quality time, communication, teamwork, and appreciation of each other.

Internet Safety and Social Media

In our modern society, social media is one of the most common ways we communicate with one another. As parents, our main goal is to keep our children safe and healthy. One important way to help them stay safe is to teach them social media safety habits.

Mental Health

Mental health includes our emotional, psychological, and social well-being. It affects how we think, feel, and act. It also helps determine how we handle stress, relate to others, and make choices. Mental health is important at every stage of life, from childhood and adolescence through adulthood.

Physical Health and Nutrition

Good nutrition, physical activity, and healthy body weight are essential parts of a person’s overall health and well-being.

Social Emotional Learning

Social and emotional learning (SEL) is an integral part of human development. SEL is the process that helps people develop healthy identities, manage emotions, feel empathy for others, maintain supportive relationships with friends or family members as well as make responsible decisions.

Supporting School Success

Parental involvement, such as attending school functions like back-to-school nights and concerts or volunteering in the library, is as important as helping with homework. Many working parents find it particularly hard to be a presence in their children’s school. However, research indicates that it is worth the effort.
