A Vegetarian Hostel Player Who Fades in the Last Twenty Minutes
Simran is 17, a Class XII student in a girls' hostel, 165 cm tall and 52 kg, and the main raider for her school kabaddi team. She trains six days a week for 90 minutes and often skips breakfast because the mess opens late. Her typical day is two cups of tea before school; at 11 a.m. two plain parathas with pickle; at 3 p.m. a packet of biscuits; at 8 p.m. three chapatis with potato sabzi and a little curd; and tea again at 10 p.m. She complains of tiredness in the last 20 minutes of every session, a stitch-like pain in her side, and a mild calf cramp at night. Her haemoglobin at the school health check was 10.1 g/dL. She is a vegetarian, her family sends about ₹2,000 a month for extra food, and there is no refrigerator in the hostel room.
1. From the diet recall and symptoms, identify the two most probable nutritional problems and justify each with specific evidence rather than general advice.

Problem 1 – low iron availability, with probable iron-deficiency anaemia. Haemoglobin 10.1 g/dL is below the normal range for an adolescent girl. The diet contains almost no non-haem iron sources: no dal, no green leafy vegetables, no jaggery, no groundnuts. Worse, tea is taken at 10 p.m. and around meals, and the polyphenols in tea bind non-haem iron and cut its absorption sharply. Fatigue in the last 20 minutes of a 90-minute session fits reduced oxygen-carrying capacity.
Problem 2 – poor carbohydrate timing and energy availability. There is a nine-hour gap between the 11 a.m. parathas and the 8 p.m. dinner, bridged only by biscuits. Afternoon biscuits give quick sugar but no sustained glycogen, so her muscle glycogen is nearly empty by the closing minutes of training. The same gap, plus low fluid and sodium intake, explains the side stitch and night calf cramp – night cramps are commonly linked to low calcium, magnesium and sodium and to dehydration, and her curd intake is minimal.
Why the reasoning matters. Fatigue and cramps are non-specific. The answer only becomes usable when each symptom is tied to a specific gap in the recall – iron and tea for the fatigue and haemoglobin, meal spacing for the late-session collapse – because that is what tells you which change to make first. A haemoglobin of 10.1 also needs medical referral; diet alone is not a treatment plan.
2. Redesign her day using the hostel mess plus ₹2,000 a month, and explain the timing logic behind the changes.

Budget check first. ₹2,000 a month is about ₹65 a day, so the plan must use cheap local foods: banana, roasted chana, groundnuts, jaggery, milk, seasonal green vegetables, amla or guava when available.
Revised day
- On waking / before training: banana and a handful of roasted chana kept in the room (no refrigerator needed). Fixes the skipped breakfast and puts carbohydrate in the blood before a 90-minute session.
- 11 a.m.: the same two parathas plus a bowl of dal or curd from the mess. Adds protein and iron and slows the release of energy.
- 3 p.m.: replace biscuits with chana, groundnuts or a glass of milk. Removes the sugar spike-and-crash.
- Within 30–60 minutes after training: banana or jaggery with water – glycogen refills fastest in this window.
- 8 p.m.: three chapatis, dal, a green leafy vegetable, curd, and a lemon squeeze or amla. Vitamin C taken with the iron-rich food markedly improves absorption of non-haem iron.
- 10 p.m.: replace tea with milk. Milk supplies calcium and protein and does not block iron absorption.
Timing logic. The three failures in the original day were an eight-to-nine-hour fuel gap, no protein at any meal, and tea at the worst possible moments. Every change above attacks one of these, and none of them costs more than ₹20 a day.
3. Why does the tea at 10 p.m. and with meals matter more than it appears to, and what would you tell Simran about it?
Read the worked answer
Two separate mechanisms, both real.
Iron. Tea contains tannins and polyphenols that form insoluble complexes with non-haem iron from cereals and vegetables. Two cups of strong tea with or just after a meal can reduce iron absorption from that meal substantially. In a vegetarian diet, where all the iron is non-haem and already poorly absorbed, this is a decisive loss – it is one of the most common and most fixable causes of low haemoglobin in Indian hostel diets.
Sleep. Tea at 10 p.m. delivers caffeine close to bedtime. Caffeine has a half-life of roughly three to five hours, so a large part of it is still circulating at midnight. Sleep loss then worsens perceived fatigue, recovery and appetite control, which makes the training fatigue worse and can be misread as 'not enough food'.
What to tell her. Not 'stop drinking tea' – that advice is ignored. Say: keep tea if you like it, but move it to between meals, at least an hour away from food, and never after 6 p.m.; pair iron-rich meals with lemon, amla or guava; and treat the haemoglobin of 10.1 as something to show a doctor rather than something to solve with diet alone. The judgement being tested is that a small habit can outrank a big dietary change.
