Additionally, overweight children have self-esteem issues and a lower quality of life. Obese children have an 80% chance to stay that way once they reach 35 years old. And, even though they might lose weight in the future, overweight or obese teenagers have a tendency to have a higher mortality risk by any cause, especially in the case of cardiovascular diseases.

Therefore, it’s urgent to detect this problem as soon as possible so children are healthy and have an adequate weight throughout their whole life. So, it’s necessary to visit a nutritionist to help the child lose the weight and follow a healthy diet.

How do we know if a child is overweight or obese?

When you suspect that your child is gaining weight, take them to the pediatrician or nutritionist to check their body composition. To assess the child’s physical state, it’s necessary to take a look at size, weight and body mass index (BMI).

Unlike adults, the World Health Organization (WHO) has set a specific percentiles of size, weight and BMI, according to age and sex. Thus, a child is overweight when above the 85th percentile.

How do we put a child on a diet?

First, it’s essential to understand the concept of a diet. It doesn’t refer to a strict diet in which you starve and eliminate food, but rather it consists of eating healthy food and reeducating the child and the family so that they learn to eat healthy.

Nutrition education

For a child to lose weight, the whole family must learn to eat healthy food. A very useful resource is the Harvard Healthy Eating Plate, which consists of vegetables and fruits in half of the plate, animal protein (meat, fish, eggs, dairy) or plant-based protein (legume) in a quarter of the plate, and whole grains or tubers (bread, pasta, rice, potato) in the rest of the plate.

On the other hand, it’s important to eliminate food with a high caloric density and a low nutritional density, such as pastries, breakfast cereals, juice, cookies, etc. This type of food could be left for special occasions or replaced by homemade sweets.

Portion reduction

Children shouldn’t follow a hypocaloric diet. They should adjust the amounts to their weight, sex and age, since they could be eating more than they should. Mothers don’t want their children to be hungry, but it’s important for them to recognize when they’re overeating.

At first, reducing portions or filling the plate with vegetables might be of help, since it contributes to feeling full.

Increasing physical activity

If the child doesn’t do exercise, we have to encourage them to move and play a sport. Nutrition isn’t enough; it’s the combination of nutrition and physical activity that will help them lose weight in a healthier and quicker way.

Therefore, if your child is overweight or obese, don’t hesitate to see a nutritionist to teach them how to eat and establish proper dietary habits, in order to prevent them from being an obese adult in the future.
