Class at 9, technique at 11, rehearsal from 2 to 6, a granola bar somewhere in between, and dinner standing up at 9 p.m. Meanwhile the studio has floor-to-ceiling mirrors, the costumes are skin-tight, and someone is always talking about “the line”. That’s the setting for dance nutrition: high energy needs in an art form where body shape gets judged. This page is honest about that tension. It covers eating enough (and what happens when you don’t), the warning signs of eating disorders and where to get help, bone health, and the few supplements worth a look, with third-party testing.

General information, not personal medical or nutrition advice. For a plan that fits you, talk to your doctor or a registered dietitian, ideally a sports dietitian who works with dancers. Back to the dance hub.

Dancers are athletes, and athletes need fuel

The International Association for Dance Medicine & Science (IADMS) calls dancers “artistic athletes” who need enough energy from all the major food groups to keep their metabolism, hormones and growth working, on top of what dancing costs. Its nutrition paper suggests most dancers need about 4–8 grams of carbohydrate per kilogram of body weight a day (more during long or intense rehearsal periods), and protein of about 1 g/kg a day for female dancers and 1.5 g/kg for male dancers, up to 2 g/kg when building muscle. It warns that diets promising rapid weight loss by cutting out food groups are likely to hurt performance and health, and that dietitians are the most qualified people to advise.

In practice: three real meals plus snacks you can actually eat between classes (fruit, yogurt, a sandwich, nuts, cheese and crackers), carbohydrate at every meal, and a bigger meal or snack on the long days. For timing around shows, see performance and competition day.

Low energy availability and REDs, honestly

Energy availability is what’s left from the food you eat after the energy you spend training, to run everything else: growth, hormones, bones, immune system, brain. When it’s too low for too long, the result is what the International Olympic Committee (IOC) calls Relative Energy Deficiency in Sport (REDs). The IOC’s 2023 consensus says it affects both female and male athletes, can happen on purpose (dieting) or by accident (not keeping up with a heavy schedule), and can harm periods and hormones, bones, metabolism, iron status, immunity, mental health and performance. It also points to the growing role of too little carbohydrate in particular.

Dance is a high-risk setting. In an international survey of 247 dancers in serious training (85% in ballet), 57% of female and 29% of male dancers reported signs consistent with low energy availability, and fewer than a third had even heard of REDs. In a study of 50 competitive female dancers, lower energy availability scores went along with more injuries. IADMS adds two important points: low energy availability often happens unintentionally during heavy periods, and dancing well doesn’t prove you’re fine, because performance isn’t always affected at first. Common early signs are fatigue, poor concentration and lost or irregular periods.

What helps, following the IOC’s prevention advice: education for dancers, parents and teachers, and taking the focus off weight and leanness, especially for young and pre-professional dancers. In plain studio terms: no public weigh-ins, no comments on bodies, and no “you’d jump higher if you were lighter”. A missed or stopped period is never a normal part of training; it’s a reason to see a doctor.

Eating-disorder warning signs and where to get help

A 2014 review of 33 studies found that about 12% of dancers had an eating disorder (16.4% of ballet dancers), and that dancers were about three times as likely as non-dancers to have one. IADMS says disordered eating and eating disorders are common in dancers, affect men as well as women, and lists early signs of disordered eating: rigid all-or-nothing food rules, avoiding eating with others, going long periods without eating or skipping meals on purpose, regimented calorie counting, and guilt, shame or anxiety around food. The National Institute of Mental Health (NIMH) adds very restricted eating, intense fear of gaining weight, a distorted body image, eating in secret, purging and excessive exercise, and stresses that people who look healthy can still be seriously ill.

If you’re worried about yourself or a friend, don’t stay silent; IADMS urges dancers to tell a teacher, parent or someone who can help. Start with a family doctor or pediatrician, who can connect you to a mental health professional and a registered dietitian. Eating disorders are treatable, and NIMH says early treatment matters. In the U.S., the ANAD Eating Disorders Helpline is free at 1-888-375-7767 (Monday to Friday, 9 a.m. to 9 p.m. Central). If someone is in crisis or thinking about self-harm, call or text 988 (Suicide & Crisis Lifeline).

Bone health

IADMS’s bone health paper explains that 50–60% of bone mass is built during puberty, with peak bone mass reached before about age 20, and that dancers who develop low bone density in their teens may never fully regain it. Studies back up the concern: vocational ballet students (boys and girls) had lower bone density than non-dancers at all sites measured, and in a Belgian ballet school about a third of 14- and 15-year-old students had lower-than-expected bone density. Low energy, missing periods and low calcium intake all play a part, and IADMS notes that dancers with low energy and calcium intake have relatively high rates of stress fractures (see dance injuries).

• Calcium: dairy and fortified foods are the richest sources (IADMS). The U.S. recommended amount is 1,300 mg a day for ages 9–18 and 1,000 mg for adults 19–50 (NIH).
• Vitamin D: IADMS says many dancers are low, especially in winter, from long hours indoors. A little daily time outside helps; ask your doctor whether to test or supplement.
• Iron: include iron-rich foods. IADMS notes dancers with heavy periods may need iron, which blood work can confirm; don’t take iron “just in case”, because too much is harmful.

Supplements: food first

IADMS advises meeting vitamin and mineral needs from food, says a basic daily multivitamin is reasonable for dancers with restricted diets or limited food access, and warns that high-dose vitamins aren’t needed and can be toxic. On protein powders: “no magic”, just good-quality protein, so know why you’re taking one and check that it contains what the label says. IADMS also warns against herbal “cleanses” and diuretic or laxative teas for changing weight. For young dancers, the American Academy of Pediatrics says energy drinks have no place in children’s and teens’ diets and advises against creatine under 18. Weight-loss pills, “fat burners”, diet teas and laxatives have no place in dance.

Why third-party testing matters

Supplements can contain substances that aren’t on the label; one widely cited study found undeclared prohormones in about 15% of 634 products from 13 countries. Breaking was an Olympic sport at Paris 2024, and athletes in drug-tested competition are bound by “strict liability”: a positive test is the athlete’s responsibility, whatever the label said. Programs like NSF Certified for Sport and Informed Sport (which IADMS itself points to for protein powders) test products and batches for banned substances. They reduce the risk, but don’t eliminate it.

Dance nutrition: FAQs

How much should a dancer eat?

Enough to match training, growth and daily life, which for most dancers is more than they think. IADMS suggests about 4–8 g of carbohydrate per kg a day and roughly 1–1.5 g of protein per kg, but needs vary a lot, so a sports dietitian is the best guide.

What is RED-S in dancers?

Relative Energy Deficiency in Sport: health and performance problems caused by not eating enough for the energy you spend. The IOC says it affects female and male athletes and can harm hormones, bones, mood and performance. In one survey, 57% of female and 29% of male dancers showed signs of low energy availability.

Is it normal for a dancer to lose her period?

No. Common doesn’t mean normal. Missing or irregular periods are a key warning sign of low energy availability, which IADMS links to lower bone density. See a doctor, ideally one familiar with athletes.

How do I know if a friend in my class has an eating disorder?

Watch for skipped meals, strict food rules, avoiding eating with others, secret eating, extra exercise, and constant focus on weight or shape. Tell a trusted adult; IADMS says “don’t stay silent”. The ANAD helpline (1-888-375-7767) offers free support; in a crisis, call or text 988.

Do dancers need supplements?

Most don’t. Food comes first. A basic multivitamin can make sense for restricted diets, and vitamin D or iron only if a doctor finds you need them. Choose third-party tested products (NSF Certified for Sport, Informed Sport) and avoid anything sold for weight loss.
