Why do children gain weight during vacations, and what can be done?
Children and teenagers gain weight two to three times faster during vacations than during the school year. Experts at the Meir Medical Center explain that this is due to disrupted routines and offer a multidisciplinary program to help families maintain a healthy lifestyle.
Children and teenagers may gain weight at a higher rate during summer vacations and holidays. According to studies conducted in the USA, Canada, Australia, and other countries, the rate of weight gain during this period can be double and sometimes even triple compared to school months. At the Sports and Health Center for Children and Youth at Meir Medical Center, experts suggest addressing this phenomenon through a multidisciplinary framework that operates year-round.
According to Prof. Danny Nemet, who heads the center, the school year routine includes fixed sleep and wake times, walking to school, physical education classes, and active play. During vacations, however, spontaneous activity often decreases, screen time increases, and eating becomes less mindful, especially when accompanied by snacks, sweets, or sugary drinks.
The center explains that sleep also plays a critical role in weight management. Disruptions to sleep schedules can throw off the daily routine and increase appetite. Prof. Nemet notes the recommended daily sleep durations:
-
Children aged 3–5: 10–13 hours
-
Children aged 6–12: 9–12 hours
-
Teenagers aged 13–18: 8–10 hours
The program at Meir includes physical activity adapted to each child's needs, aiming to improve fitness, cardiovascular endurance, and muscle strength. Alongside exercise, children and their families are provided with tools for nutrition and healthy lifestyle habits. The program has been cited by the American Academy of Pediatrics as one of the world's most effective proven multidisciplinary programs.
Prof. Nemet emphasizes that the family is a vital partner in the process:
"One of the fundamental principles of the program is that change does not happen in the child alone. The family is a full partner, as a supportive home environment is a significant component of long-term success."
The center also runs a joint project with the Olympic Committee, where Olympic athletes meet and train with the children's groups. Activities at the center are fee-based.
