Extreme dieting has become increasingly common among young adults, prompting growing concern among health professionals about its impact on physical and mental health.
“Many young people are turning to extreme diets because they are promised fast results without being informed of the risks involved,” said Dr. Amanda Lee, a public health nutritionist.
Extreme dieting often includes severe calorie restriction, prolonged fasting, or the elimination of major food groups such as carbohydrates and fats.
According to medical experts, these practices can disrupt normal metabolism and lead to serious nutrient deficiencies.
“When the body does not receive enough energy, it begins to conserve fuel by slowing down essential bodily functions,” explained Dr. Jason Wong, a medical officer.
Health professionals report that individuals who follow extreme diets commonly experience fatigue, dizziness, dehydration, and weakened immune systems.
Women may face additional health risks, including hormonal imbalances and irregular menstrual cycles linked to prolonged restrictive eating.
“The physical effects are visible, but the psychological consequences are often hidden and ignored,” said Dr. Nur Aisyah Rahman, a clinical psychologist.
Mental health experts warn that extreme dieting can create an unhealthy relationship with food and body image.
“When food is seen as an enemy, the risk of eating disorders such as anorexia and bulimia increases significantly,” Dr. Rahman added.
Social media has been identified as a major influence, with diet trends spreading rapidly through influencers and viral content.
“These platforms often promote unrealistic body standards without scientific evidence to support their claims,” said Professor Daniel Smith, a media and health studies expert.
Nutritionists emphasise that sustainable weight management should be based on balanced nutrition rather than extreme restrictions.
“There is no healthy shortcut to weight loss, and professional guidance is essential for long-term well-being,” said registered dietitian Sarah Collins.
Health authorities continue to call for greater awareness and education to protect young adults from the dangers of extreme dieting.
