Nutrition & Fuel

Yes — this is the whole foundation, and most girls under-do it. When you train, you spend energy your body still needs for growing, focusing, and recovering, so training more means eating more, not less. A 2023 study of adolescent athletes found they burned significantly more energy than non-athletes but often didn't eat enough to match — and it showed up as fatigue, brain fog, and irritability. More training is a reason to eat more, not a reason to tighten up.

Simple and balanced: a source of carbs (rice, pasta, potatoes, bread, fruit), a source of protein (eggs, chicken, yogurt, beans, fish), some fat (avocado, nuts, oil), and color from vegetables or fruit. Carbs are your main fuel, protein rebuilds you, fat keeps your hormones running — you need all three, not one at the expense of the others. This isn't about "clean" or "bad" foods; it's about giving your body enough of each job to do its work.

No — carbs are your body's preferred fuel, especially for sport. They're what your muscles burn during hard efforts and what refills your energy stores afterward, and cutting them is one of the fastest ways to feel flat, foggy, and weak in training. The idea that carbs are "bad" is diet-culture noise that has no place in an athlete's kitchen. Fuel with them, don't fear them.

Yes — the window after training is when your body is primed to restock energy and start repairs, so getting some carbs and protein in within an hour or so helps you recover and show up better next time. It doesn't have to be fancy: chocolate milk, yogurt and fruit, a sandwich, or a real meal all work. Recovery fueling matters most when training is frequent and heavy. The goal is "soon and simple," not "perfect."

Honestly, no — the research doesn't back the idea that breakfast has special magic, and your total fuel across the whole day matters more than any single meal. But here's why it still matters for you specifically: if you train and have a packed school day, skipping breakfast usually means you never catch up on fuel, so you run the afternoon and practice on empty. It doesn't need to be big or elaborate — it just needs to keep you from starting the day in a hole.

Plan for the gaps. Long school days plus practice mean there are hours where you can't sit down to a meal, so the fix is portable fuel you can actually eat between classes and before training — trail mix, fruit, yogurt, a sandwich, a bar you don't hate. Under-eating during the school day is often just a logistics problem, not a willpower one. Stock your bag like it's part of your gear.

More than most teen girls get. For an active girl with a real training load, the evidence supports roughly 1.4–1.7 g of protein per kg of bodyweight per day — concretely, for about a 130 lb athlete that's roughly 80–100g a day, spread across meals rather than dumped into dinner. Around 20–25g of real-food protein within 30–60 minutes after training helps you recover. Whole foods (eggs, dairy, chicken, legumes) beat powders for this age group; most teens don't need supplements at all.

Both, but total and spread matter most. Getting a source of protein at each meal — rather than almost none until dinner — gives your body a steady supply to repair and build with across the day. Around training, pairing protein with carbs helps recovery. You don't need to obsess over minutes; you need to stop skipping it at breakfast and lunch.

Almost certainly not to hit your needs — real food (eggs, dairy, meat, fish, beans, soy) covers protein for the vast majority of teen athletes, and it comes with other nutrients powders don't. A shake can be a convenient backup when you're rushed or can't stomach a meal, but it's a tool, not a requirement, and it's not "better" than food. Save your money and eat first; supplement only to fill a real gap.

It can, especially on heavy training days. A small protein-containing snack before bed (yogurt, milk, cottage cheese) fits the bigger principle that matters most — spreading protein across the day rather than cramming it into one meal — and gives your body material to repair with overnight. It's genuinely useful, not a rule. And if you're hungry at night, that's information, not weakness. Fuel it.

For most training, water is your best sports drink — plain and simple. Electrolyte and sports drinks earn their place in long, hot, sweaty sessions (think 60+ minutes, tournaments, high heat), but for everyday practice they're mostly unnecessary sugar and marketing. Hydrate consistently through the day rather than chugging right before you train. Water first; electrolytes when the session is genuinely long or hot.

Because you're losing it monthly and burning through it in training, and low iron quietly wrecks performance — showing up as unusual fatigue, breathlessness, and struggling in sessions you used to handle. Iron deficiency is common and underdiagnosed in adolescent female athletes precisely because the symptoms look like "just being tired." If you're constantly wiped out, iron is worth checking with a doctor, alongside your fueling. Menstruating athletes are the highest-risk group for exactly this.

Because these are the raw materials for the bone you're building during a once-in-a-lifetime window. Roughly 90% of your peak bone density is set by your early 20s, and calcium plus vitamin D are what your body uses (alongside weight-bearing training) to bank it. Dairy, fortified foods, leafy greens, and some sun cover a lot of it. Skimp now and you can't fully make it up later.

Don't fear it — you need it. Healthy fats (avocado, nuts, seeds, olive oil, fish) are essential for hormones, including the ones that run your cycle and your recovery, and cutting fat too low can disrupt exactly those systems. Fat is not the reason athletes gain or lose performance; under-fueling overall is. Include it as a normal part of your plate.

Energy drinks are not sports drinks — they're high-caffeine, high-sugar products, and in teens heavy use has been linked to real problems: disrupted sleep, anxiety, jitteriness, and in extreme cases seizures. The caffeine load in some cans is a lot for a still-developing system, which is why the general guidance is to avoid them at this age. If you're leaning on them to get through the day, the real fix is almost always more fuel and more sleep — not more caffeine.

Before: carbs are the priority, with a little protein, a few hours out — pasta, rice, a sandwich — so your tank is full without a heavy stomach. After: carbs plus protein, soon, to restock energy and start repair before your next session. The harder and more frequent your competition, the more this matters. Keep it familiar on game day; don't try new foods before you compete.

Treat it as continuous fueling, not one big meal. Long days with multiple games or races mean topping up with easy carbs and some protein between efforts — fruit, sandwiches, bars, familiar snacks — so you don't run empty by the afternoon. Hydrate steadily throughout. The athlete who fuels between rounds outlasts the one who ate a huge breakfast and nothing else.

Real, portable, and a mix of carbs and protein: fruit with yogurt or cheese, trail mix, a peanut-butter sandwich, granola, a bar you genuinely like. The best snack is the one you'll actually eat and that travels in your bag. Snacks aren't "extra" for a training teen — they're often where a big chunk of your fuel comes from.

Yes — an athlete's diet has room for real life. You can fuel well from most menus by aiming for the same balance you would at home: a carb, a protein, and something with color, in a portion that matches how much you're training. No single meal makes or breaks you; the overall pattern is what counts. Ditch the "good food / bad food" framing — it does more harm than a burger ever will.

It's completely doable, but it takes a little more intention around protein and iron. Lean on beans, lentils, tofu, dairy or fortified alternatives, eggs (if you eat them), nuts, and whole grains, and pay extra attention to iron since plant iron is absorbed less easily (pairing it with vitamin C helps). Plant-based athletes can absolutely thrive — the risk isn't the diet, it's under-planning it.

Completely normal, and it's biological, not a lack of willpower. In the phase before your period your body's energy demands and blood-sugar sensitivity shift, so increased hunger and cravings are expected — your body is literally asking for more fuel. The move is to respond with real, satisfying food, not to fight it. Hunger is information, and around your period it's information worth listening to.

Yes — "clean eating" can quietly become under-eating, and that's a real risk for athletes. When the focus narrows to only "perfect" foods, portions often shrink and whole food groups (like carbs and fats) get cut, leaving you under-fueled even though you feel disciplined. Rigid food rules can also start to run your life and break your hunger signals. Fueling well means eating enough, not eating "perfectly."

Because it is. Hunger is your body's signal that it needs fuel — treating it as something to suppress or feel guilty about teaches you to ignore one of your most useful internal cues. Athletes who learn to respond to hunger with real food recover better and train better than those who override it. You're not supposed to be a little hungry all the time; that's a sign you're under-fueling, not a sign you're doing it right.

Backwards, and it's the most important myth to kill. When you chronically don't eat enough to cover both training and growing, you can develop RED-S (Relative Energy Deficiency in Sport), which damages the exact things you're trying to build — bone, hormones, and recovery. A 2025 meta-analysis of 59 studies and over 6,000 athletes found 44% of female athletes met the criteria for low energy availability — this is close to the norm, not a rare edge case. Under-eating doesn't sharpen you; it breaks you down.

Neither is true. Protein is a basic building block every athlete needs to repair and grow — it's not male, and it doesn't create bulk on its own; girls simply don't have the hormone levels for that. Under-eating protein leaves you recovering worse and building less of the strength you're training for. Girls build strength from training and protein comparably to boys in relative terms — without the bulk, because they don't have the hormone levels for it. Eat it because you train, full stop.

It's a warning light, not a win. Losing your period can signal RED-S — energy intake too low to support basic function — and it travels with stress fractures, illness, poor recovery, and stalled performance. If your period disappears, that's a real reason to talk to a sports-medicine-literate doctor, not something to accept or celebrate. Long term, under-fueling weakens bone and can stall both your cycle and your development.

"Toning" is a marketing word, not a physiological process. What people call "toned" is just having muscle and being well-fueled enough to see and use it — which comes from strength training and eating enough, not from tiny weights and eating less. Chasing "tone" through restriction usually gets you the opposite: less muscle and less energy. Train for strength and fuel it; the look takes care of itself. Sports scientists note that "toning" is a cultural framing, not a distinct physiological process — the underlying reality is building muscle and fueling well.
