Carbohydrates have developed a pretty bad reputation.
For years, we’ve heard that carbs make you gain weight, spike your blood sugar, or should be avoided if you want to get lean.
But carbohydrates are neither inherently “good” nor “bad.”
They’re a source of energy, and the right amount depends on your individual goals, activity level, overall diet, and how your body responds to different foods.
If you’re regularly doing CrossFit, strength training, Hyrox, running, or high-intensity exercise, carbohydrates can play an important role in fueling your workouts and supporting recovery.
So what exactly are carbohydrates, and which ones should you be eating?
What Are Carbohydrates?
Carbohydrates are one of the three macronutrients, along with protein and fat.
Your body breaks down many carbohydrates into glucose, which can be used by your cells as an energy source. Glucose is important during higher-intensity exercise, when your body relies heavily on carbohydrate metabolism to produce energy.
Carbohydrates include foods such as:
- Fruits
- Vegetables
- Potatoes and other root vegetables
- Rice
- Oats
- Quinoa
- Beans and legumes
- Bread and pasta
- Sugars and sweets
The important distinction is that the nutritional quality of these foods can be very different.
Do We Actually Need Carbohydrates?
Technically, carbohydrates are not considered an “essential” macronutrient in the same way that certain amino acids and fatty acids are essential nutrients.
Your body can produce glucose through processes such as gluconeogenesis, and it can use ketones as an alternative fuel source under certain conditions.
But that doesn’t mean carbohydrates are unnecessary.
For active people, carbohydrates can be a very useful, and sometimes the preferred source of fuel.
They can help support:
- High-intensity exercise
- Training volume
- Recovery
- Glycogen replenishment
- Daily energy needs
- Intake of fiber, vitamins, minerals, and other beneficial plant compounds
The question isn’t necessarily “Do I need carbs?”
A better question is:
“How much carbohydrate do I need for my goals and activity level?”
Why Carbohydrates Matter for Exercise
If you’re doing a demanding workout, your body needs readily available energy.
Muscles store carbohydrate in the form of glycogen, which can be used during exercise.
This becomes particularly important during activities that involve repeated bursts of high intensity, such as CrossFit, sprinting, martial arts, and many team sports.
If your carbohydrate intake is too low for your training demands, you may notice:
- Lower workout intensity
- Reduced endurance
- Increased fatigue
- Difficulty maintaining training volume
- Slower recovery
That doesn’t mean everyone needs a high-carbohydrate diet.
It means your carbohydrate intake should make sense for how much you’re training and what you’re trying to accomplish.
What Are the Best Carb Sources?
Not all carbohydrate-rich foods provide the same nutritional value.
Instead of labeling foods simply as “good carbs” or “bad carbs,” look at the overall nutritional package.
Fruits and Vegetables
Fruits and vegetables provide carbohydrates along with fiber, vitamins, minerals, and various plant compounds.
Examples include:
- Berries
- Bananas
- Apples
- Oranges
- Squash
- Carrots
- Beets
- Leafy greens
- Peppers
They’re excellent choices for building a nutrient-dense diet.
Potatoes and Root Vegetables
Potatoes, sweet potatoes, yams, and other root vegetables can be excellent sources of carbohydrate.
They’re useful around training because they’re relatively easy to incorporate into meals and provide energy along with nutrients such as potassium.
Rice and Other Grains
Rice, oats, quinoa, and other grains can provide a convenient source of carbohydrate, especially for active people with higher energy requirements.
They’re also easy to portion based on your training demands.
Beans and Legumes
Beans, lentils, and other legumes provide carbohydrates along with protein and fiber.
They’re nutrient-dense foods that can be an excellent part of a balanced diet.
What About Refined Carbohydrates?
Refined carbohydrates aren’t automatically “bad.”
White rice, for example, can be a perfectly reasonable food for an athlete, even around training when easily digested carbohydrates may be useful.
The bigger issue is relying heavily on ultra-processed foods and added sugars while crowding out more nutrient-dense foods.
Cookies, candy, pastries, sugary drinks, and many packaged snack foods can provide a lot of calories without providing much protein, fiber, vitamins, or minerals.
These foods can absolutely fit into a healthy diet, but they shouldn’t make up the majority of your carbohydrate intake.
Think mostly whole or minimally processed foods, rather than trying to eliminate every refined carbohydrate.
Carbohydrates and Digestion
How well you tolerate certain carbohydrates depend on the individual.
Fiber, food volume, cooking method, portion size, and the presence of other nutrients can all influence digestion.
For example, a large serving of raw vegetables may feel very different from cooked vegetables.
Similarly, some people tolerate rice and potatoes extremely well while experiencing digestive discomfort from certain grains, legumes, or high-fiber foods.
There is no universal list of “easy” and “hard” carbohydrates.
Your individual tolerance matters.
If a particular food consistently causes bloating or digestive discomfort, experiment with portion size, preparation method, timing, and alternative foods.
Does Cooking Change Carbohydrates?
Cooking can change the physical structure of carbohydrate-containing foods and affect how they’re digested.
For example, cooking generally softens plant foods and can make some carbohydrates easier to digest.
Cooling cooked potatoes or rice can also increase the amount of resistant starch in the food, although the effect varies based on the food and preparation method.
The takeaway isn’t that one cooking method is universally superior.
Choose the preparation method that makes the food nutritious, enjoyable, and comfortable for you to digest.
Carbs, Protein, and Fat: The Bigger Picture
One of the biggest nutrition mistakes is focusing on one macronutrient in isolation.
Carbohydrates don’t exist in a vacuum.
Most meals contain some combination of carbohydrates, protein, and fat.
At CrossFit 626, we encourage members to prioritize adequate protein first, particularly when the goal is building or maintaining muscle.
From there, carbohydrate and fat intake can be adjusted based on individual goals, activity levels, preferences, and tolerance.
For someone training hard several days per week, reducing carbohydrates excessively may make it harder to maintain workout intensity and recover.
For someone who is sedentary and primarily focused on reducing calorie intake, their carbohydrate needs may be considerably lower.
There is no single macronutrient ratio that works for everyone.
When Should You Eat Carbohydrates?
Carbohydrate timing can be useful for athletes, but total daily intake generally matters more than trying to find the “perfect” time to eat carbs.
That said, many active people benefit from including carbohydrates before and after training.
Before Training
A carbohydrate-rich meal or snack before exercise can provide readily available energy.
Examples include:
- Banana with Greek yogurt
- Oatmeal and fruit
- Rice with lean protein
- Potatoes with eggs
After Training
Carbohydrates after exercise help replenish muscle glycogen, especially when training again within a relatively short period.
Combining carbohydrates with protein also provides the nutrients needed to support recovery.
How Many Carbs Should You Eat?
Your carbohydrate needs depend on several factors:
- Body size
- Training frequency
- Training intensity
- Overall calorie intake
- Performance goals
- Body composition goals
- Individual tolerance and preference
Someone training hard six days per week will generally have different carbohydrate needs than someone exercising twice per week.
Instead of following an arbitrary number, pay attention to performance, recovery, hunger, energy, and changes in body composition.
If your workouts consistently feel flat and recovery is poor, your overall energy or carbohydrate intake may need to be reconsidered.
The Bottom Line
Carbohydrates aren’t something you need to fear.
They’re one of the three macronutrients. And for active people, they can be an important source of fuel for high-intensity training and recovery.
Focus on nutrient-dense carbohydrate sources most of the time: fruits, vegetables, potatoes, rice, oats, whole grains, and legumes.
At the same time, there’s no need to treat every refined carbohydrate as toxic or completely off-limits.
The best nutrition plan is one that provides enough protein, appropriate amounts of carbohydrates and fats, plenty of micronutrients, and enough flexibility to fit your lifestyle.
At CrossFit 626, we believe nutrition should support your training, and not make your life harder. The goal isn’t to eliminate carbs. It’s to learn how to use them strategically to support energy, performance, recovery, and long-term health.
