    Episode 207: Why "Just Lose Weight" Won't Fix Your Gymnast's Puberty Struggles

    Have you noticed your gymnast suddenly feeling weaker or struggling with skills she used to hit easily, and wondered if she's just gained "too much weight"? It's tempting to think the fix is simple: get her lighter and the skills will come back. But in this episode, Christina explains why that logic misses something important, and why "just lose weight" almost always backfires. Around age 11, girls enter puberty and their bodies change exactly as nature intends: gaining height, weight, and shifting biomechanics. Trying to stop that with dieting or underfueling does not solve the problem, it makes it worse. You cannot build strength, muscle, or bone in a calorie deficit, and you certainly cannot recover from 20 to 30 hours a week of training in one. Puberty is one of the most anabolic phases in a female's life. The body is building a stronger skeleton, more muscle, a bigger heart, and a mature reproductive system, all of which require energy. Restrict that fuel and the body compromises: performance suffers, recovery slows, hormones get disrupted, and injury risk rises. It's not because the gymnast is weak, it's because physiology always wins. Christina compares two gymnasts: one who loses weight by eating less but also loses muscle, endurance, and recovery capacity, and one who moves through puberty well-fueled, gaining some body fat but also gaining muscle. The second gymnast almost always performs better, because body weight is just one of more than 40 factors that determine performance. She also touches on when body composition changes do reflect a genuinely disordered relationship with food, and why getting fueling right from the earlier competitive levels matters so much long-term. Fixing this takes two things: consistent, adequate nutrition, and well-programmed, progressive strength and conditioning designed by specialists, not leftover conditioning lists. In this episode, we cover:  ❗ Why "just lose weight" seems logical, but doesn't hold up  ❗ What's happening in a gymnast's body when she enters puberty  ❗ Why you cannot build strength, muscle, or bone in a calorie deficit  ❗ A tale of two gymnasts: underfueled weight loss vs. healthy, fueled weight gain  ❗ Why body weight is only one of 40+ factors that determine performance  ❗ What low energy availability does to injury risk, hormones, and recovery  ❗ Why strength and conditioning needs to be specialist-designed, not an afterthought  ❗ When body composition changes do signal a disordered relationship with food Christina's takeaway: puberty is not something to fight, it's something to fuel and prepare for. Gymnasts who are properly fueled and supported through this transition come out the other side stronger and more resilient.

    Episode 206: Should Gymnasts Weigh Less to Prevent Injury?

    Have you ever heard a coach or well-meaning adult say something like "gymnasts need to watch their weight so there's less pressure on their joints"? It sounds scientific. It sounds logical. And it can make a parent start to wonder if their gymnast should be smaller to protect her joints. But here is the problem: that statement only tells half the story. In this episode, Christina breaks down the physics and the physiology behind gymnast injury risk, and why trying to make a growing gymnast lighter is not the same thing as making her safer. The physics part is true. Landing forces in elite gymnastics can reach six to thirteen times an athlete's body weight, and a lighter athlete does experience less external force on identical landings. But injuries are not determined by physics alone. They come down to whether the body is actually prepared to absorb that force. Christina walks through what does the absorbing: muscles, tendons, bones, ligaments, and the nervous system. Think of it like a truck's suspension system. It is not the weight of the truck that smooths out the bumps, it is the suspension. For a gymnast, her muscles, tendons, and bones are that suspension. And building that suspension requires fuel. When a gymnast underfuels, she ends up with low energy availability, meaning her body does not have enough calories to grow, repair, recover, and adapt from training. The result is earlier fatigue, slower reaction time, worse recovery, and poor training adaptation, all of which increase injury risk rather than lowering it. Christina explains the real framework sports medicine uses: load versus capacity. Load includes things like number of landings, skill difficulty, training hours, and body weight. Capacity includes muscle strength, bone health, tendon health, landing mechanics, sleep, recovery, and fueling. You can lower the load by making an athlete smaller, or you can build her capacity, and the best injury prevention strategies focus on capacity. This matters even more for growing, developing gymnasts going through puberty. Weight gain, body fat gain, and growth spurts during this stage are normal biology, not something to diet against. Restricting a gymnast through puberty interferes with normal growth and bone development, and tends to backfire. Christina also unpacks what the research on RED-S (Relative Energy Deficiency in Sport) actually says, and why the International Olympic Committee identifies underfueling, not body weight, as the biggest nutritional threat to an athlete's health and performance. In this episode, we cover: ❗ Why the "extra pounds equal extra force on joints" statement only tells half the story ❗ How landing forces actually work in elite gymnastics ❗ Why physics tells us how much force hits the body, but not whether the body can handle it ❗ What actually absorbs landing forces: muscles, tendons, bones, ligaments, and the nervous system ❗ Why underfueling leads to low energy availability, and what that does to performance ❗ Why RED-S identifies underfueling, not body weight, as the biggest threat to athlete health ❗ The load versus capacity framework sports medicine uses to think about injury risk ❗ Why strong, well-fueled muscles absorb force and fatigued muscles transfer it to bones and growth plates ❗ Why weight gain and growth spurts during puberty are normal biology, not a problem to fix ❗ Why restricting a growing gymnast's food can interfere with bone development and backfire long-term ❗ Why resilient, well-fueled athletes recover better, train harder, and stay healthier and in the sport longer ❗ How to shift the question from "how do I make her lighter" to "how do I help her body get stronger" Christina's takeaway: the goal is not to create the lightest gymnast in the gym. It is to create a gymnast whose body can tolerate thousands of landings, recover from them, and keep getting stronger.

    Episode 205: Why Your Gymnast Needs Two Meals Before Summer Training

    Have you noticed your gymnast sleeping in later this summer and then heading straight to practice after only one meal? Maybe practice starts at 10 a.m., 11 a.m., noon, or even early afternoon. And because it falls in that awkward window between breakfast and lunch, it can be hard to know what your gymnast actually needs to eat before training. But here is the problem: One meal before a four- to five-hour summer practice is usually not enough. In this quick tip episode, Christina breaks down why gymnasts need more structure with their fueling during summer training, especially when practice starts mid-morning or mid-day. During the school year, gymnasts often get more consistent nutrition because their schedule is more structured. But in the summer, everything shifts. Gymnasts may stay up later, sleep in longer, and wake up with barely enough time to eat before heading to the gym. And while they may be able to “make it through” practice on one meal, that does not mean they are properly fueled. Christina explains why underfueling during summer upgrade season can impact performance, recovery, inflammation, and injury risk. Because the goal is not just to survive practice — it is to come out of summer stronger, healthier, more confident, and ready for preseason and competition season. In this episode, we cover: ❗ Why summer training schedules can make fueling harder ❗ Why one meal before gym is usually not enough ❗ Why “feeling fine” does not mean your gymnast is properly fueled ❗ How underfueling can impact recovery, repair, and performance ❗ Why missing nutrition can increase inflammation and injury risk ❗ Why gymnasts may need to go to bed earlier and wake up earlier ❗ Why upper-level gymnasts with big goals need more structure ❗ Why a custom summer fueling plan can make a huge difference Christina also shares an example of an upper-level gymnast whose summer schedule led to her missing a significant amount of her daily nutrition compared to the school year. And this is the important reminder: If your gymnast only has one meal by 3 or 4 p.m., that is not enough nutrition. Even if she can get through practice. Even if she says she feels fine. Even if she does not seem hungry. Gymnasts need enough fuel before, during, and after training to support performance, recovery, bone health, muscle repair, and long-term success in the sport. This is especially important for upper-level gymnasts training long hours, working upgrades, and trying to stay healthy heading into preseason and competition season. Your gymnast may need help understanding the “why” behind her fueling plan. And that is okay. When gymnasts understand how fueling impacts their goals, they are much more likely to buy in, follow through, and make the changes they need. If your gymnast has a 10 a.m., 11 a.m., 11:30 a.m., or noon summer practice time, there is a good chance she needs more support with her summer fueling schedule. She may need two meals before training, an intra-workout fueling plan, and a better post-workout recovery plan. Because upgrade season is not the time to underfuel. It is the time to fuel well, recover well, and set your gymnast up to feel stronger, healthier, and more confident for the season ahead.

    Episode 204: Do Gymnasts Really Need Sports Drinks?

    Have you ever wondered if your gymnast actually needs a sports drink at practice? Maybe you have seen other athletes drinking Gatorade, Powerade, Liquid I.V., LMNT, Prime, BodyArmor, or electrolyte packets and wondered if your gymnast should be doing the same. Or maybe you have heard that sports drinks are “toxic,” full of sugar, dyes, or ingredients your gymnast should avoid. But here is the problem: the conversation around sports drinks is often missing the most important piece. Context. In this episode, Christina breaks down what parents actually need to know about sports drinks, electrolytes, hydration, sugar, and performance nutrition for gymnasts. And one thing is very clear: Sports drinks are not automatically toxic. But they are also not automatically necessary. They were created for a very specific purpose: to help athletes replace fluid, electrolytes, and carbohydrates during long, intense training sessions, especially when sweat losses are high. Christina explains why sports drinks contain both electrolytes and sugar, why sodium matters for hydration, and why sugar is not just there for taste. In the right context, carbohydrates can help with both hydration absorption and fueling during training. But for most gymnasts, especially recreational, lower-level, or shorter-duration athletes, water and food-based fueling are often enough. The gymnasts who may benefit most from sports drinks are typically upper-level athletes training intensely for several hours, especially when they struggle to eat during practice, have limited snack breaks, or need an easier way to get intra-workout carbohydrates. In this episode, we cover: ❗ Why sports drinks are not “toxic” ❗ Why sports drinks were originally created ❗ Why electrolytes like sodium, potassium, and chloride matter ❗ Why sugar in sports drinks has a purpose ❗ Why hydration needs are different from fueling needs ❗ Why most gymnasts do not need sports drinks for regular practice ❗ When a sports drink may be helpful for upper-level gymnasts ❗ Why food-based carbs are often a better option for younger or lower-level gymnasts ❗ Why sipping on sports drinks for hours can increase cavity risk ❗ Why Gatorade Zero and low-sugar options are not the same as traditional sports drinks ❗ Why electrolyte packets, oral rehydration solutions, and sports drinks are not all the same thing ❗ Why products like Prime, BodyArmor, Liquid I.V., LMNT, and Skratch need to be evaluated differently ❗ Why influencer marketing can make sports nutrition confusing for parents ❗ Why fueling your gymnast properly should come before spending money on electrolyte products Christina also explains why more is not better. Your gymnast does not need 30, 40, or 50 ounces of sports drink during practice. If a sports drink is being used, it should be part of a larger fueling and hydration strategy, not the only beverage she drinks. And if your gymnast does need extra electrolytes, food can help too. Something as simple as pretzels can provide sodium along with carbohydrates and other nutrients. The goal is not to fear sports drinks. The goal is to understand when they make sense, when they do not, and how to choose the right option for your gymnast’s specific needs. Because nutrition is not about blanket rules. It is about context. And when it comes to gymnast fueling, the healthiest choice is always the one that helps your gymnast stay fueled, hydrated, supported, and able to train safely.

    Episode 203: 5 Lessons Learned in 11+ years as a Peds/Adolescent Sports Dietitian for Gymnasts

    Have you ever wondered if your gymnast is actually eating enough to support everything her body is being asked to do? Maybe she is training hard, dealing with injuries, struggling with fatigue, or trying to keep up as her body grows and changes. And maybe from the outside, everything looks mostly fine. But here is the problem: underfueling in gymnastics is often much more common than most parents realize. In this episode, Christina shares five of the biggest lessons she has learned in 11 years as a pediatric and adolescent sports dietitian, including the last six years working exclusively with gymnasts. And one thing has become very clear: Gymnast nutrition is not just about eating “healthy.” It is about eating enough, at the right times, in a way that supports growth, puberty, bone health, recovery, training, performance, and long-term health. Because underfueling does not only happen to level 9s, 10s, and elites. It can start much earlier. Christina explains why younger gymnasts, including level 4, 5, and 6 athletes, can already be underfueled, injured, struggling with growth, or not getting enough nutrition to keep up with the demands of the sport. And when those issues are not addressed early, they often become bigger as training hours increase, puberty begins, and performance expectations grow. In this episode, we cover: ❗ Why underfueling is more common in gymnasts than many parents realize ❗ Why younger gymnasts can be underfueled too ❗ Why early nutrition support matters ❗ Why gymnast nutrition needs are often downplayed ❗ Why gymnasts need enough fuel for training, growth, puberty, and recovery ❗ Why carbohydrates are so important for gymnastics ❗ Why fatigue, burnout, mental blocks, and inconsistency may require a deeper look ❗ Why HTMA testing can offer insight into mineral depletion and stress patterns ❗ Why “healthy eating” sometimes has to take a back seat to adequate fueling ❗ Why puberty, body diversity, and genetics matter in gymnastics ❗ Why fueling for performance should always come before aesthetics Christina also shares why adequate fueling is a safety concern. Your gymnast’s body cannot recover, repair, grow, adapt, or perform well if it does not have enough energy and nutrients to do so. And for many gymnasts, waiting until she is older, higher-level, motivated, or already injured means waiting too long. The goal is not to force a perfect diet. The goal is to build a fueling foundation that helps your gymnast stay healthy, train consistently, recover better, and keep doing gymnastics for as long as she wants to. Because your gymnast should get to decide when she is done with the sport. Not her injuries. Not burnout. And not underfueling.

    Episode 202: What ChatGPT doesn’t know about your gymnast’s nutrition: AI can’t get your kid to eat right

    Are you asking ChatGPT, AI, Google, or Facebook groups how to get your gymnast to eat better? Maybe you already know she needs breakfast, more snacks, more protein, more carbs, or better recovery fuel. Maybe you have asked AI for meal plans, snack ideas, calorie needs, or supplement recommendations. And maybe the answer sounded helpful. But here is the problem: AI can tell you what your gymnast might need to eat, but it cannot actually help her do it. In this episode, Christina wraps up her four-part series on what ChatGPT and AI do not know about your gymnast’s nutrition. Today’s focus is the part so many families struggle with most: implementation. Because most parents do not just need more information. They need help figuring out why their gymnast is not eating enough, why breakfast feels hard, why snacks are skipped, why hunger cues are unreliable, why picky eating gets in the way, or why body image and food fears make fueling feel complicated. AI does not know your gymnast’s growth history, injury history, appetite patterns, food preferences, training demands, family dynamics, puberty status, or the real-life barriers that show up day after day. And it cannot coach your gymnast through those barriers. In this episode, Christina explains why nutrition success is not just about knowing what to eat. It is about habits, consistency, routines, accountability, and having a plan that actually works for your gymnast’s life. In this episode, we cover: ❗ Why AI can explain nutrition but cannot create behavior change ❗ Why knowing what to eat is not the same as doing it consistently ❗ Why under-fueled gymnasts may not feel hungry ❗ Why breakfast struggles often require problem-solving, not just ideas ❗ Why picky eating needs a realistic fueling plan ❗ Why body image, food fears, and weight concerns need human support ❗ Why AI-generated meal plans often fall apart ❗ Why individualized nutrition coaching matters for growing gymnasts AI can give you a snack list. It can write a meal plan. It can explain carbs, protein, and recovery fuel. But it cannot understand what is actually getting in the way for your gymnast. And that is where individualized support matters. Your gymnast does not need another generic meal plan from the internet. She needs a plan that meets her where she is, supports what her body is being asked to do, and helps her build the consistency she needs to grow, recover, train, and perform well. So if you have tried the AI answers, the Facebook group suggestions, the snack lists, and the meal plans, but your gymnast is still tired, under-fueled, injured, anxious around food, picky, or struggling to recover, the better question is not just, “What should she eat?” The better question is, “What is getting in the way of her doing it?” And that requires individualized support, not a generic AI answer.

    Episode 201: What ChatGPT Doesn’t Know About Your Gymnast’s Supplements

    Are you asking ChatGPT, AI, or Facebook groups what supplements your gymnast needs? Maybe your gymnast is tired, sore, injured, getting sick often, struggling to recover, or not gaining strength — and as a parent, you just want to help. So you ask: Does she need magnesium? Iron? Creatine? Electrolytes? Protein powder? A multivitamin? But when it comes to pediatric and adolescent gymnasts, supplements are not that simple. In this episode, Christina continues her four-part series on what ChatGPT and AI do not know about your gymnast’s nutrition, and today’s focus is supplements. Because while AI can give you a polished answer or a list of recommendations, it cannot accurately assess whether your gymnast actually needs those supplements. It does not know if she is eating enough, growing appropriately, recovering well, fueling consistently, or whether her symptoms are actually signs of under-fueling. And this matters. Because no supplement can make up for not eating enough. Many of the things parents try to fix with supplements — fatigue, soreness, poor recovery, frequent illness, injuries, slow strength gains, or stalled progress — are often connected to under-fueling, not a missing supplement. In this episode, Christina breaks down why “food first” matters, why supplement recommendations require context, and why individualized nutrition support is so important for growing gymnasts. In this episode, we cover: ❗ Why AI and online searches cannot determine your gymnast’s supplement needs ❗ Why supplements should never replace eating enough food ❗ Why fatigue, soreness, injury, and poor recovery are often signs of under-fueling ❗ Why creatine, protein powder, iron, magnesium, electrolytes, and multivitamins all require individualized context ❗ Why iron supplements can be harmful if your gymnast does not actually need iron ❗ Why supplement quality and third-party testing matter ❗ Why social media supplement recommendations can be misleading ❗ Why parents may spend more on random supplements than they would on individualized support ❗ What parents should ask instead of, “What supplement does my gymnast need?” AI may be able to generate a supplement recommendation. But it cannot evaluate your gymnast’s growth, fueling, recovery, labs, training demands, injury history, symptoms, and health context the way an experienced pediatric and adolescent sports dietitian can. Your gymnast does not need a random supplement stack from the internet. She needs the right nutrition foundation first. Enough food. Enough carbs. Enough protein. Enough calories. Enough consistency. And then, if there are true gaps, supplements can be used intentionally and individually. Because supplements are just that — supplements. They are meant to fill in what is missing, not fix under-fueling. So if your gymnast is tired, sore, injured, sick often, struggling to get stronger, or not recovering well, the better question is not, “What supplement should she take?” The better question is, “Is she eating enough to support what her body is being asked to do?” And that requires individualized support, not a generic AI answer.

    Episode 200: What ChatGPT Doesn't Know About Your Gymnast's Nutrition: Calorie Needs

    Are you asking ChatGPT, AI, or an online calculator how many calories your gymnast needs? It might seem like a simple question. But when it comes to pediatric and adolescent gymnasts, calorie needs are anything but simple. In this episode, Christina continues her four-part series on what ChatGPT and AI do not know about your gymnast’s nutrition, and today’s focus is calorie needs. Because while AI can give you a polished answer, a number, or even a full meal plan, it cannot accurately assess what your gymnast’s body actually needs based on growth, puberty, training volume, recovery, injury status, health history, and where they are in their season. And for gymnasts, this matters. A young gymnast training 20 to 30 hours a week may need more nutrition than a parent, sibling, coach, or another athlete their age, even if they are smaller in size. Because calorie needs are not determined by body size alone. They are determined by what your gymnast’s body is being asked to do: grow, develop, repair, recover, and adapt to training. In this episode, Christina breaks down why calorie needs are so hard to estimate, why hunger is not always a reliable sign of whether your gymnast is eating enough, and why online calculators and AI tools often miss the bigger picture. Because your gymnast’s body is not a math problem. It is a growing, developing athlete with dynamic needs that change across growth spurts, puberty, training seasons, injury recovery, and daily life. In this episode, we cover: ❗ Why AI and online calculators cannot accurately determine your gymnast’s calorie needs ❗ Why calorie needs are dynamic and change throughout the year ❗ Why two gymnasts of the same age, size, and training level can still need very different amounts of food ❗ Why “my gymnast is small, so she must not need much food” is a dangerous myth ❗ Why hunger cues can become suppressed when a gymnast is under-fueled ❗ Why many gymnasts need to eat even when they are not hungry ❗ How growth, puberty, training volume, recovery, injury status, and daily movement impact nutrition needs ❗ Why basic metabolism is only one part of the equation ❗ Why recovery requires fuel for up to 48 hours after training ❗ How under-fueling can show up as fatigue, injury, headaches, dizziness, poor recovery, delayed puberty, stalled skills, low motivation, anxiety, and emotional shutdowns ❗ Why slowed growth or delayed development can be a sign your gymnast is not getting enough nutrition ❗ Why calorie targets alone do not tell the full story ❗ What parents should look at instead of asking, “How many calories does my gymnast need?” AI may be able to generate a number. But it cannot evaluate your gymnast’s growth chart, training demands, puberty status, injury history, recovery, mental health, performance, and fueling patterns the way an experienced pediatric and adolescent sports dietitian can. Your gymnast does not need a generic calorie target. They need enough nutrition to support everything their body is trying to do: grow, develop, repair, recover, stay healthy, and get stronger from the work they are putting in. And that requires individualized support, not an online calculator.
