Today we’re tackling one of the most controversial questions in gymnast nutrition:
Should gymnasts eat candy during competitions?
This question comes up constantly in my DMs especially after Instagram posts or stories where I mention quick carbs, gummies, or candy as part of a competition fueling strategy. Inside the The Balanced Gymnast® Program, we take a deep dive into this topic because it’s nuanced, science-based, and often misunderstood.
Between social media sound bites, fear-based nutrition messaging, and confusion around sugar, insulin, and blood sugar, it’s no wonder parents and coaches feel overwhelmed. Today, we’re breaking down when candy can be strategic, when it’s not needed, and how to think about sugar during gymnastics competitions without fear.
My Background in Nutrition and Sports Science
On the surface, recommending candy during a competition sounds like an oxymoron especially coming from someone trained in endocrinology and diabetes education.
Early in my career, I worked in pediatric endocrinology, where I became a Certified Diabetes Educator (I’m now a former CDE). I spent years working with children and adolescents managing:
- Type 1 diabetes
- Type 2 diabetes
- Hormonal disorders such as thyroid conditions and growth hormone deficiencies
This role gave me a deep understanding of blood sugar regulation, insulin, and carbohydrate metabolism, knowledge that directly informs how I now approach performance nutrition for gymnasts.
At the same time, my background in sports nutrition includes training under elite mentors and working with athletes at the highest levels. That combination is exactly why I’m so intentional about how and when sugar is used.
How Quick Carbs and Candy Can Impact Competition Fueling
In sports nutrition, you’ll often hear recommendations for quick-digesting carbohydrates also called simple carbs or simple sugars around intense training and competition.
These sports nutrition recommendations aren’t random. They’re based on:
- Exercise physiology
- Digestion speed
- Muscle fuel demands
- Nervous system activation
During exercise, the body’s relationship with carbohydrates changes dramatically. The goal of competition fueling isn’t “healthy eating” it’s performance optimization.
That distinction matters.
Foods recommended before, during, or immediately after training may look very different from everyday meals and that’s intentional.
Why Eating Candy Can Be Strategic
Candy is most commonly recommended during competitions, not daily practice.
That’s because intra-competition fueling has unique demands:
- Long meet days
- Multiple events
- High adrenaline
- Mental fatigue
- Limited digestion windows
This is an advanced fueling strategy, typically most relevant for:
- Upper-level optionals
- Level 10 gymnasts
- Elite athletes
- Gymnasts training 20–30+ hours per week
For compulsory gymnasts or those training fewer hours, candy is often unnecessary and that’s okay. Fueling strategies should match training volume, intensity, and maturity, not trends. For a full meet-day plan, see What to Eat Before a Gymnastics Meet.
When Candy Isn’t Needed
Candy is not recommended for:
- Short practices
- Low-intensity training
- School snacks
- Sitting in class or studying
In these situations, quick sugar can cause blood sugar fluctuations that don’t support focus or energy.
This is why fruit snacks alone aren’t considered a balanced snack; they’re a fun food, not a fuel strategy.
Parents’ Concerns About Sugar, Insulin, and Crashes
A common fear is that sugar causes a “blood sugar crash.”
Here’s what’s important to understand:
When gymnasts are exercising, muscle contractions activate a glucose transporter (GLUT-4) that allows sugar to move directly into the muscles without needing insulin.
This means:
- Insulin response is reduced during exercise
- Muscles actively pull sugar from the bloodstream
- The risk of a crash is significantly lower
There are protective mechanisms during training that do not exist when sitting still.
That’s why sugar can be problematic at rest, but useful during competition.
Blood Sugar Management During Exercise
In some cases, gymnasts may experience symptoms if sugar is consumed too early, especially if:
- Warm-up is long
- Intensity ramps slowly
- High-intensity work is delayed
This is why fueling must be timed, not random.
For gyms with immediate, intense conditioning at the start of practice, quick carbs can be helpful. For others, they may be better used mid-competition or later in the session.

Candy Isn’t Automatically the Best Choice
Just because candy can be used doesn’t mean it should be the default.
Whenever possible, we prioritize:
- Fruit
- More complex carbohydrates
- Nutrient-dense options
If a gymnast isn’t meeting basic nutrition needs, candy isn’t the fix: adequate daily fueling is.
Candy is a tool, not a foundation.
Sugar Addiction & Restriction Concerns
Many parents worry their gymnast is “addicted to sugar.”
In reality:
- Most gymnasts aren’t eating enough overall
- Restriction increases fixation
- Labeling foods as “bad” fuels obsession
This is especially important for gymnasts with:
- Type 1 diabetes
- Celiac disease
- Food allergies
Rigid rules increase anxiety and reduce trust in hunger cues. (More on this in Can Gymnasts Eat Junk Food? and What Is Food Freedom?)

Gym Policies, Autonomy, and Safety
Blanket gym rules banning snacks or sports drinks often harm the athletes who need fueling the most.
While cleanliness and behavior matter, nutrition and hydration are safety issues especially for upper-level gymnasts.
Fuel access should never be used as a punishment.
Frequently Asked Questions
For some upper-level optional, Level 10 and elite gymnasts with long meet days, small amounts of quick carbs like candy or gummies can help keep energy up. Many gymnasts, especially at lower levels, don’t need it.
A crash is much less likely during exercise. Working muscles pull sugar out of the bloodstream without needing much insulin, so quick carbs are used as fuel instead of causing a big spike and drop.
Candy isn’t the right fuel for short practices, low-intensity training, school snacks or sitting still. It also isn’t a fix for not eating enough during the day.
Fruit, fruit snacks, dried fruit, pretzels, a sports drink or a few pieces of candy all work. Use foods she has already tried at practice.
Final Thoughts
So is candy helpful or harmful for gymnasts?
The answer is context-dependent.
For a small subset of advanced gymnasts, candy can:
- Support performance
- Maintain blood sugar
- Prevent fatigue
- Improve focus during long competitions
For others, it’s unnecessary.
The key is understanding why, not just copying strategies.
