Visualizing 700g of Carbohydrates
Visualizing a 700-gram intake of carbohydrates can be difficult, as it is a significant amount of food. This quantity is not typical for the average person and is generally reserved for highly active individuals like endurance athletes who need to maximize their energy stores before a major competition. The total caloric intake from this amount of carbs alone is 2,800 kcal (since each gram of carbohydrate contains approximately 4 calories), so achieving this requires strategic and intentional eating throughout the day.
The Volume of Food
To put 700g of carbs into perspective, consider the following food equivalencies based on common carb sources:
- White Bread: Approximately 45 slices of standard white bread.
- Pasta: Around 1.5 kilograms (over 3 pounds) of cooked white pasta.
- White Rice: Roughly 10 cups of cooked white rice.
- Bananas: Over 20 medium-sized bananas.
Achieving this intake through whole foods alone can be challenging due to the sheer bulk. This is why athletes often rely on a combination of high-carb foods and concentrated carb sources like sports drinks, gels, and bars to meet their daily targets. The goal is to consume low-fiber options where possible to reduce bulk and potential gastric issues during competition.
Comparing Carb Sources
Not all carbohydrates are created equal, especially when aiming for a high intake like 700g. Endurance athletes often need to balance fast-acting and slow-releasing carbs. The following comparison table highlights the differences between common simple and complex carbohydrate sources for carb-loading.
| Feature | Simple Carbohydrates (e.g., White Bread, Sports Drinks) | Complex Carbohydrates (e.g., Brown Rice, Oats) |
|---|---|---|
| Digestion Speed | Rapid; provides quick energy | Slower; provides sustained energy |
| Fiber Content | Low | High (though athletes may reduce this during final loading) |
| Nutrient Density | Lower in vitamins and minerals | Higher in vitamins, minerals, and fiber |
| Glycemic Index | Typically higher | Typically lower |
| Satiety | Less filling, easier to consume in large quantities | More filling, can lead to feeling bloated |
A Day of 700g Carbs: Sample Meal Plan
Here is an example of what a day of eating could look like for an athlete aiming for 700g of carbohydrates, distributed across multiple meals and snacks to make it manageable. This plan prioritizes lower-fiber options closer to the event to minimize gastrointestinal distress.
Breakfast
- 50g Cornflakes with 200ml 1% milk.
- 2 medium bananas (carbohydrate: ~50-60g).
- Large glass of orange juice (carbohydrate: ~40g).
Mid-Morning Snack
- 2 large raisin bagels with jam (carbohydrate: ~100-120g).
- Energy sports drink (carbohydrate: ~60g).
Lunch
- Large portion of chicken and white rice (approx. 2 cups cooked) with a low-fat sauce (carbohydrate: ~120g).
- 2 slices of white bread with honey (carbohydrate: ~40g).
Mid-Afternoon Snack
- Dried fruit mix (100g) and a large banana (carbohydrate: ~90-100g).
- Energy sports drink or concentrated carb gel (carbohydrate: ~60g).
Dinner
- Large plate of pesto pasta (approx. 2 cups cooked) with sweet potato (carbohydrate: ~150g).
- Garlic bread (carbohydrate: ~30g).
- Rice pudding (200g) with jam (carbohydrate: ~50g).
The Strategic Rationale Behind High Carb Intake
For athletes, the logic behind a high carbohydrate intake, particularly a carb-loading strategy, is to supersaturate muscle glycogen stores. Glycogen is the stored form of glucose, and it is the primary fuel source for high-intensity, prolonged exercise. When these stores are topped off, an athlete can sustain peak performance for longer without hitting the dreaded 'wall' that occurs when glycogen is depleted. This is why carb-loading is a crucial strategy for marathon runners, cyclists, and other endurance athletes.
Furthermore, carbohydrate intake is vital for muscle recovery post-exercise. During intense training, muscle glycogen is used up. Replenishing these stores after a workout is critical for recovery and preparing for the next session. High-carb meals, like the ones outlined above, help to efficiently restock these energy reserves, ensuring the athlete is ready to perform again.
It is important to understand that a diet of 700g of carbohydrates is not suitable for everyone. It is a highly specialized approach used for a short period leading up to a specific, intense physical event. For the general population, a balanced diet is recommended, and such high levels of carbohydrate intake would likely lead to weight gain if not balanced with an extreme exercise regimen.
Conclusion
What does 700g of carbs look like? It looks like a substantial, full day of eating focused primarily on carbohydrate-rich foods, strategically designed for maximum glycogen storage. It's a volume of food that can be challenging to consume and is only appropriate for elite endurance athletes in a carb-loading phase. By combining whole food sources like rice and pasta with concentrated sports nutrition products, athletes can achieve this high intake to fuel their performance and prolong endurance. The key takeaway is that this is not a one-size-fits-all approach but a targeted, practiced strategy for specific athletic goals.

The Role of Glycogen and Athletic Performance
Glycogen serves as the body's main reservoir of fuel for high-intensity, long-duration activities. Think of your muscles as fuel tanks; carb-loading is the process of filling those tanks to the brim. During exercise, your body breaks down glycogen into glucose, which is then used by your muscles for energy. By consuming 700g of carbohydrates, athletes ensure that they have a maximal supply of this fuel, delaying fatigue and maintaining a higher intensity for longer. Without adequate carbohydrate intake, an athlete's glycogen stores can become depleted, leading to a significant drop in performance. The strategic timing and type of carbohydrates consumed during the loading period are crucial to avoid gastrointestinal issues and ensure the energy is readily available when needed most.
