Cutting Three Kilos in Three Days
Anjali, 16, a state-level wrestler in the 50 kg category, weighs 52.4 kg three days before the official weigh-in and is told she must make weight. Since Monday she has eaten one meal a day - cucumber, tomato and black tea - trained twice daily in a sweatshirt, and spent twenty minutes in the school sauna each evening. She is dizzy on standing, has a headache, her urine is dark, and her periods have stopped for two months. Her coach calls this 'discipline'; her mother is frightened. Anjali wants to lose 3 kg by Friday and asks the physical education teacher for a 'water-cut' plan, a sauna schedule and diet pills. She is 160 cm tall, weighs 52.4 kg, and her skinfold sum is the lowest in the team.
1. Judge whether Anjali's current method is safe. Link each sign she shows to its physiological cause.

The method is not safe and should not be supported by the teacher.
- Dizziness on standing: low blood volume from dehydration plus low blood glucose from near-fasting causes orthostatic hypotension.
- Dark urine and headache: concentrated urine means she is already significantly dehydrated. A loss of 2% of body mass as fluid (about 1 kg) is enough to reduce strength, reaction time and thermoregulation; she is trying to lose 3 kg (about 5.7%) in three days.
- Amenorrhoea for two months, lowest skinfolds in the team, food restriction and fear of weight gain: this combination points to the Female Athlete Triad / RED-S (disordered eating, menstrual dysfunction, bone-density risk). Diet pills and sauna 'water cuts' are classic disordered-eating behaviours, not discipline.
- Sauna plus training in a sweatshirt: heat load without fluid replacement raises the risk of heat exhaustion and kidney stress.
Performance consequence: she will weigh in lighter but will compete glycogen-depleted, dehydrated and with poor thermoregulation - typically weaker, slower and at higher injury risk. The teacher should refuse the water-cut and sauna plan, inform the parents and school, and refer her for medical and nutritional assessment.
2. Work out a safe alternative. Estimate her energy and protein needs, the realistic rate of loss, and state what she should do about Friday's weigh-in.

Energy: for an active 16-year-old athlete, roughly 45–50 kcal per kg body mass, i.e. 52 × 45–50 ≈ 2,340–2,600 kcal/day including training. A safe deficit is 300–500 kcal/day, giving an intake of about 2,000–2,200 kcal/day.
Rate of loss: a 500 kcal deficit yields about 0.5 kg fat loss per week; 0.25–0.5 kg/week (roughly 0.5–1% of body mass) is the accepted safe range. Losing 2.4 kg at this rate needs 5–6 weeks, not three days. That calculation alone shows the plan is impossible without dehydrating her.
Protein and carbohydrate: protein 1.2–1.5 g/kg ≈ 62–78 g/day; carbohydrate 5–7 g/kg ≈ 260–360 g/day to fuel twice-daily training; fat about 0.8–1 g/kg; 2.5–3 L fluid spread across the day; iron- and calcium-rich foods (pulses, leafy vegetables, milk, jaggery, eggs) to protect bone and blood.
Friday's weigh-in: she should not attempt a 3 kg cut. The correct options are to compete in the 52 kg category if it exists, or to withdraw, weigh in at natural weight and begin a structured 6–8 week plan for the next competition. A small supervised reduction (0.5–0.8 kg) in the last week, achieved by reducing salt and refined food rather than by fluid restriction, is the maximum acceptable.
3. How should the physical education teacher respond to the coach's attitude and to the request for diet pills, while keeping the athlete in sport?
Read the worked answer
Refuse the request clearly and record it. Diet pills are not a teaching aid; stimulant-based slimming pills carry cardiac and dependence risks, and providing or facilitating them is outside a teacher's role. Say no, explain why in one sentence, and document the conversation.
Do not attack the coach publicly. Instead bring data: her skinfolds, her missed periods, her dizziness and the calculation showing 2.4 kg cannot be lost safely in three days. Propose a written weigh-in policy - no sauna suits, no fluid restriction, weigh-in no more than 4 weeks before competition, minimum body-fat screening - which protects the coach from being blamed when an athlete underperforms.
Keep her in sport. The goal is not to remove her but to redirect the same discipline into planning: a food diary, weekly weighing under the same conditions, a 6–8 week target, and a younger-category or higher-weight-category option.
Escalate. Involve parents, the school counsellor and a doctor. Amenorrhoea for two months plus rapid weight loss in a 16-year-old is a medical issue, and if she continues restricting food or induces vomiting, referral for suspected anorexia nervosa is required, not persuasion.
