The hostel vegetarian who runs out of petrol

Two separate problems are being confused because both produce fatigue.

1. Fuel timing and quantity (acute fatigue).

• Training at 7 a.m. after only tea and biscuits means she starts on an empty tank. Overnight liver glycogen is largely used up; without a pre-training snack she is running on borrowed energy.
• Lunch is low in total energy and protein for a state-level player: two chapatis and one katori dal is roughly a sedentary portion. There is no pre-practice or post-practice feeding at all.
• The 5 p.m. samosa and cola supply quick sugar and fat but almost no protein, vitamins or minerals - energy that arrives late and leaves fast.
• Fading in the second hour, in repeated 30-second sprints, fits glycogen depletion plus dehydration.

2. Iron status (chronic fatigue).

• Hb 9.6 g/dL is anaemia, and heavy six-day periods are a plausible ongoing cause of iron loss. Low haemoglobin means less oxygen delivered per heartbeat, so her sprint recovery is poor.
• Her diet is not iron-poor so much as iron-inefficient: vegetarian iron is non-haem, absorbed at only a few per cent, and she drinks tea with the very meal where absorption should happen. Tannins in tea inhibit non-haem iron absorption.
• Potato, cabbage and rice are not iron-rich; there are no green leafy vegetables, no legumes beyond one katori of dal, no jaggery, dates or groundnuts.

So the honest answer is: her diet fails on adequacy, on meal timing and on iron bioavailability simultaneously.

Change the plate, then change the pairing.

• Never train on tea and biscuits. Add a pre-practice snack 45–60 minutes before: poha with groundnuts, a banana with curd, or two stuffed parathas. This directly fixes the second-hour fade.
• Add a post-practice snack within about 30–45 minutes: curd rice, a groundnut-jaggery chikki, or dal-roti with a fruit. Muscles refill glycogen fastest in this window.
• Build iron into the day: green leafy vegetables (palak, methi) at least four times a week, whole legumes (chana, rajma, moong), jaggery, dates, groundnuts, sesame (til) and, if available, iron-fortified atta.
• Pair iron with vitamin C at the same meal. Lemon on dal, amla or guava after lunch, tomato in the sabzi. Vitamin C converts ferric to ferrous iron and sharply improves non-haem absorption.
• Move tea and coffee to at least an hour after meals, not with them - this removes the tannin block. The same applies to calcium: avoid a big glass of milk with the iron-rich meal.
• Reduce phytate by soaking, sprouting and fermenting - sprouted moong, idli, dhokla, fermented batter. These traditional methods genuinely improve mineral absorption.
• Combine proteins across the day: rice plus dal, roti plus curd, cereal plus legume. Together they supply all essential amino acids that neither supplies alone.
• Fix fluid and salt: two to three glasses of water before practice, and lemon-salt-sugar water for long sessions.

The message to her is that no single food is the answer; the pairing and the timing are.

No - not as planned, and the reason is a judgement about who decides.

• Self-prescribed iron is not harmless. Iron is dosed according to haemoglobin and ferritin, body weight and the cause of the loss. Excess iron causes constipation, nausea and, in overdose, serious harm. Two tablets a day chosen by a senior student is guesswork.
• Taking it with tea is doubly wrong - tannins reduce absorption, which is exactly the problem the tablet is meant to solve.
• The correct route: the school health check result should go to a doctor, who will decide whether supplements are needed, at what dose, and for how long, and will recheck haemoglobin after a few weeks.
• The heavy periods need their own answer. If she is losing blood faster than she can replace iron, no diet will fully correct it; that requires medical assessment. Ignoring it and pushing training is how a treatable problem becomes a chronic one.
• Do not remove her from sport while this is sorted. She can keep training with better fuelling, hydration and a rest break in long drills; the aim is to fix the cause while she stays active.
• Record it properly: the school should note the Hb value, the referral and the review date, and the coach should know her training is being modified for a medical reason.

The exam-ready principle: dietitian or teacher advises on food, doctor decides on supplements and investigates causes, coach adjusts load. Nobody does another's job.
