Toddler Obesity: Causes And Tips To Be Healthier

Baby Tips

Obesity is defined as having excess body fat. A toddler is considered overweight when their weight is higher than the average weight for toddlers of their age. A healthy weight trajectory is one in which the toddler’s height and weight increase proportionally as they grow. When toddlers deviate from their healthy weight trajectory, it results in excess body fat, which can be harmful to their health (1).

This post will tell you all you need to know about managing your toddler’s obesity and keeping them healthy.

What Is Toddler Obesity?

Obesity is excess body fat often due to the toddler consuming more calories than they can burn. The presence of excess body fat due to obesity is a concern since it can increase the risk of developing serious health issues in the future.

There can be many reasons why a toddler could become overweight or obese, including medical and genetic conditions that cause the accumulation of excess body fat (2). However, in most cases, it is due to surplus ingestion of calories through calorie-dense food and a sedentary lifestyle.

If you think that your toddler is overweight or obese due to a medical condition, consult a pediatrician.

Toddler’s Growth And BMI

Body mass index (BMI) is the estimation of a person’s weight category based on their height and weight. You can calculate the BMI of your toddler by dividing their weight in kilograms by the square of their height in meters. It will give you a number, which is denoted by the unit kg/m2

It should be noted that BMI does not measure body fat directly but may often be correlated with more direct measures of body fat (3). Also, attaining the BMI number alone will not make it apparent if the toddler is overweight or obese. You will need a BMI percentile chart where you need to plot the toddler’s BMI.

Do note that the BMI is plotted for toddlers older than two years. Pediatricians will check only height and weight percentiles for infants and toddlers younger than two years. You may learn more about it by using our child growth percentile calculator here.

The following are the interpretations based on where your toddler’s BMI plots on the graph.

  • Below the 5th percentile: Underweight
  • Between 5th and85th percentile: Healthy
  • Between 85th and 95th percentile: Overweight
  • Equal to or higher than the 95th percentile: Obese

If your toddler falls in the overweight or obese category, consult a pediatrician. In most cases, parents may be able to tell the probable reason behind the toddler’s increased weight, which is often due to surplus calories and lack of exercise. 

What Causes Obesity In Toddlers?

Obesity and overweight in toddlers are most likely to occur due to the following reasons (4).

  • Lack of physical activity: A considerable lack of physical activity causes excess calorie retention in the body in the form of excess body fat.
  • Insufficient sleep: Insufficient sleep may be associated with obesity in some toddlers. Aspects of insufficient sleep may include late bedtimes and variable patterns in sleep schedules. These may lead to behavioral and metabolic changes, contributing to obesity over time.
  • Irregular eating schedule: If your toddler eats throughout the day without following any set schedule, they are likely to become overweight or obese.
  • Excess sugar intake: High-sugar foods are calorie-dense, and the excess calories can be quickly converted by the body into body fat, leading to overweight and obesity over time.

Some toddlers may become overweight or obese due to factors beyond their and their parent’s control, such as genetic problems, ailments, and side effects of some medicines. In such cases, the toddler may have other signs of ill health as well.

What To Do If Your Toddler Is Obese Or Overweight?

You may observe the following tips to make your toddler healthier at home.

1. Avoid excess sugars

Cut down on food items with excess sugar in your toddler’s diet. Food items with added sugars are usually loaded with sugars. An excellent example is commercially available fruit juice, which contains added sugar.

According to the American Academy of Pediatrics, fruit juices offer no nutritional benefits over whole fruit (5). Therefore, it is best to give your toddler whole fruit cut in small, easy-to-eat pieces so that they can get fiber and other nutrients that may not be present even in homemade fruit juices.

2. Encourage your child to try nutritious food

Children are known to be picky eaters. But you should encourage them to try different fruits and vegetables. Research shows that children should be given at least five portions of fruits and vegetables per day (6). A balanced diet containing food items from various food groups is the best for the toddler.

3. Ensure your toddler gets plenty of sleep

Recent studies suggest that children who get adequate sleep show signs of improved attention, behavior, mental health, and physical health (4).  Not getting enough sleep might lead to irritability and crankiness, and also increase the risk of obesity.

Toddlers between the ages of one and two years must get up to 14 hours of sleep, including naps, in 24 hours. Once they are three and older, they must get up to 13 hours of sleep, including naps, in 24 hours (7).

4. Keep screen time to a minimum

Screens should not replace parental and human interaction with a child. Increased screen time leads to decreased physical activity, increasing the risk of several health issues, such as obesity (8). Experts suggest that toddlers should not have more than an hour of screen time per day.

5. Make sure your child is getting plenty of exercise

Replacing screen time with moderate physical activity is known to help reduce the chances of obesity (9).  Take them to playgrounds or parks or let them have safe exercises at home. Making physical activity a part of their daily routine will prevent them from becoming overweight or obese in the first place.

6. Model eating nutritious food

Be a role model for your toddler and let them see you eating healthy while keeping your portions in check. Start healthy family mealtime habits, and both you and your toddler will benefit from it.

Obesity and overweight in toddlers is a growing concern, and it is even considered a non-communicable disease by the World Health Organization (10). Thankfully, it can be avoided with the right interventions. Talk to your child about the importance of healthy living and leading a healthy lifestyle. Keep their food habits and activities in check and be a role model for the qualities that you want to instill in your child for healthy living.
