The Runner Who Wants Four Kilos by Conference
Priya, 19, is a sophomore distance runner on a collegiate cross-country team. She comes to you because her coach told the team that "race weight wins championships" and she wants to drop from 54 kg to 50 kg before the conference meet in six weeks. At 168 cm she is already lean. Her training log shows 75–85 miles per week plus three lifting sessions; she runs most mornings before class on coffee and half a bagel. She has not had a period in seven months and broke her foot with a stress fracture last indoor season. She is "always freezing," even in the team van. Sleep runs about six hours. Resting heart rate is 44 bpm. Recent labs show ferritin of 14 ng/mL with everything else her team trainer called "normal," and she was cleared to compete. She uses a calorie app set to 1,600 kcal and describes herself as "good" four days a week and "out of control" on weekends. She asks for a meal plan that gets her to 50 kg.
1. Which findings would you flag, and what explanation would you give Priya for why her current plan is unlikely to make her faster?

The findings form a cluster, not a list of unrelated complaints:
- Amenorrhea for seven months in a 19-year-old endurance athlete is not a normal adaptation to training; it signals suppressed reproductive endocrine function.
- A prior stress fracture plus ferritin of 14 ng/mL point to bone and iron status that are being stressed, not optimized. Ferritin at that level is consistent with iron depletion even when hemoglobin is normal.
- Cold intolerance and a resting heart rate of 44 bpm are consistent with a down-regulated metabolic state.
- Six hours of sleep and morning runs on coffee and half a bagel mean she is training fasted and under-recovered.
- 1,600 kcal against 75–85 miles plus lifting is a large mismatch, which explains the weekend "out of control" eating - that pattern usually reflects restraint, not weak character.
The concept to teach is energy availability: what is left for basic physiology after exercise is subtracted from intake. When that surplus runs low for long enough, the body protects itself by down-regulating reproduction, bone turnover, thyroid signaling, and recovery - which is why athletes in this state get slower, injured, and sick rather than faster. Keep it educational and non-diagnostic: describe the pattern, name that it needs medical evaluation, and let the physician make the call.
2. How do you respond to the 50 kg request, and what are your next steps?
Read the worked answer
Decline the request directly but without moralizing: "I'm not going to build a plan aimed at losing four kilos right now, and I want to tell you why rather than just say no." Then give the reason in performance terms she cares about - bone stress injuries, iron, recovery, and the fact that her current intake is already mismatched to her training load.
Your next steps:
- Refer. Sports medicine physician for the amenorrhea, bone health, and ferritin, plus a board-certified sports dietitian for the eating and fueling work. Flag the restrictive app use and the binge-restrict cycle so the receiving clinician has the full picture. Consider mentioning counseling support as an option, framed as standard for athletes under this load.
- Stop the bleeding on the app. Getting rid of the 1,600 kcal target is not prescribing a diet; it is removing a tool that is actively driving restriction.
- Fuel the training she is already doing. Breakfast before morning runs, carbohydrate around sessions, three meals plus two to three snacks, and a plan for the weekend pattern.
- Sleep and recovery. Six hours is not compatible with 80-mile weeks.
- Communication, with consent. Ask Priya who may be looped in - athletic trainer, coach, team physician - and document what she agreed to.
You are not the person managing this; you are the person who notices it and routes it correctly.
3. The coach pulls you aside: "Just give her a plan - lighter is faster, and she's fine." How do you respond?

Stay professional and stay on the performance frame, because that is the coach's actual interest. Something like: "I hear that you want her fast in six weeks. That's why I'm not writing a weight-loss plan - she has a stress fracture history, no period for seven months, and ferritin of 14. Athletes in that state lose bone and lose races. I've referred her to sports medicine and a sports dietitian and I'd rather she's on the line in November than chasing a number in October."
Do not share details Priya has not consented to share. Refer to what the coach already knows - the injury, the visible fatigue - and speak in generalities about the rest. If the coach keeps pushing, route it upward: the athletic trainer or team physician is the appropriate person to hear a training-load concern, and a documented note protects both of you.
Offer a constructive alternative: a short team education session on fueling for performance, delivered to the whole roster, avoids singling out any athlete and gives the coach something to say yes to. If the coach continues to pressure an athlete toward rapid weight loss despite medical involvement, that is a program-level issue - document the conversation and escalate through the appropriate channel rather than absorbing it as your problem.
