A Crisis in Numbers
The statistics are alarming. According to the WHO, the prevalence of obesity among children and adolescents aged 5-19 rose from just 2% in 1990 to 8% in 2024. This means approximately 170 million young people worldwide are now living with obesity. The problem
is not just confined to high-income nations; it's a growing concern in low- and middle-income countries like India, which is now facing a 'double burden' of both undernutrition and a rapid rise in overnutrition. This trend is driven by increased access to ultra-processed foods, sugary drinks, and more sedentary lifestyles.
The Foundation: Lifestyle First
At the core of the new guidelines is a strong emphasis on a multi-pronged lifestyle approach. The WHO strongly recommends structured interventions that focus on diet, physical activity, and behavioural changes. Dr. Luz María De Regil, a director at the WHO, emphasized that the foundation of care is not medicine or surgery, but comprehensive support that enables sustainable healthy habits. The goal is to move beyond simply telling a child to 'eat less and move more' and instead create a supportive, family-centered environment for change.
What the Guidelines Recommend for Diet and Activity
The guidelines avoid a one-size-fits-all diet. Instead, they call for a person-centred approach tailored to the individual's age, culture, and preferences. The focus is on encouraging whole foods while limiting ultra-processed products high in fat, sugar, and salt, which are increasingly popular in India. For activity, the goal is to build regular movement into daily life, reducing sedentary time spent on screens. The WHO even gives a conditional recommendation for digital health interventions, like active video games, as long as they are supervised by a caregiver.
A Cautious Approach to Medication and Surgery
The WHO takes a notably conservative stance on more intensive treatments. For children under the age of 10, the guidelines explicitly do not recommend weight-loss drugs, bariatric surgery, or other weight-loss devices. For adolescents aged 10-19, these options are only to be considered in specific circumstances, such as cases of severe obesity where a comprehensive, supervised lifestyle program has not yielded results. This places the primary responsibility on behavioural and environmental changes, not on pharmacological quick fixes.
Beyond Weight: Focusing on Mental Health
A crucial element of the new guidelines is the focus on overall well-being, not just weight loss. The WHO acknowledges that children with obesity often face stigma, bullying, anxiety, and depression. Health workers are urged to address these mental and physical health conditions together. The recommendations emphasize the need for supportive interactions that build confidence and self-esteem, with a key instruction for healthcare providers to ask for permission before even discussing a young person's weight to help build trust.
A Call for Systemic Change
Ultimately, the WHO stresses that individual treatment alone cannot solve the obesity epidemic. The guidelines are part of a broader call to action for governments and society at large. This includes implementing policies that make healthy foods more affordable and accessible, regulating the marketing of unhealthy foods to children, and ensuring schools provide nutritious meals and opportunities for physical activity. India has been recognized for some positive steps, like limiting trans fats, but the rapid growth of the processed food market presents a major, ongoing challenge.
