Rising concern over extreme weight control habits among young people driven by social media pressures

Doctors warn that dangerous dieting and exercise habits fueled by social media are harming teenagers’ physical and mental health, prompting calls for gradual, professional-guided approaches to weight management.

Doctors have warned that an emerging obsession with slimness, fuelled by severe dieting, excessive exercise and social media pressure, is pushing some teenagers and young adults into damaging habits that can undermine both physical and mental health. The concern is not about healthy weight control, but about patterns that become rigid, punitive and difficult to stop. Research from the Endocrine Society and related medical reviews shows that when training becomes extreme and calorie intake falls too low, the body can move into a low-energy state that affects hormones, bones and reproductive health, while dehydration and prolonged exertion add further strain to the heart, brain and muscles.

Specialists say the warning signs often start with exhaustion, dizziness, poor concentration, feeling unusually cold and a drop in athletic or academic performance. In more serious cases, prolonged restriction can contribute to muscle loss, slowed metabolism, menstrual disruption, reduced fertility, weak bones and an increased risk of stress fractures. The American Academy of Pediatrics has also cautioned that unhealthy weight-loss methods can harm young athletes, raise injury risk and impair performance, while the BMJ has highlighted the dangers of a persistent mismatch between calories burned and calories eaten in sport, a pattern increasingly recognised as relative energy deficiency in sport, or RED-S.

Mental health can be affected just as sharply. Clinicians say repeated comparison with filtered or edited images online can reinforce body dissatisfaction, anxiety and obsessive checking of weight or appearance. A growing body of medical literature links severe exercise and dietary restriction with overtraining, sleep disturbance, irritability and low mood, and the effects can spill into school, work and family life. Studies on sleep deprivation also show that poor rest weakens attention, memory, reaction time and physical performance, which can make the spiral harder to break.

Doctors also caution against quick-fix slimming products, including unregulated pills, injections and herbal remedies, which may contain undeclared stimulants or other substances. Combined with heavy sweating, poor fluid intake or intense training in hot weather, these products can worsen dehydration, strain the cardiovascular system and disrupt muscle function. Medical reviews of vigorous exercise and hydration stress the importance of balancing energy, fluids and recovery, while endocrine experts say the safer route to weight management is gradual change guided by qualified professionals rather than harsh restriction or punishment-based exercise.
