Why Chips are a Poor Choice for Carb Loading
While the potato itself is a respectable carbohydrate source, the process of frying it into chips introduces a significant amount of fat, fundamentally altering its nutritional profile. A successful carb-loading strategy focuses on maximizing glycogen stores in the muscles, which are the body's primary energy source during endurance exercise. Excess fat intake can be counterproductive to this goal for several reasons.
- Displacing Vital Carbohydrates: Fat is calorie-dense, providing nine calories per gram compared to four calories per gram for carbohydrates. Consuming high-fat foods like chips can make you feel full very quickly, preventing you from reaching the high carbohydrate targets necessary for effective glycogen saturation. This means you’re filling up on the wrong fuel, leaving your muscles under-prepared.
- Risk of Gastrointestinal (GI) Distress: High-fat and high-fiber foods are known to cause stomach upset, bloating, and diarrhea, especially when consumed in large quantities before an endurance event. The last thing an athlete needs on race day is digestive issues that can derail performance. Chips, with their high fat and salt content, are a prime culprit.
- Suboptimal Nutrient Profile: Unlike whole-food carbohydrate sources, chips offer little in the way of essential vitamins and minerals crucial for an athlete's overall health and recovery. They are a source of refined carbohydrates that offer a quick but short-lived energy spike, unlike the sustained release provided by complex carbohydrates.
The Proper Way to Carb Load for Endurance
Proper carb loading is a science-backed strategy that involves intentionally increasing carbohydrate intake and reducing training volume in the 1-3 days leading up to an endurance event. This process ensures your muscle and liver glycogen stores are fully saturated, providing the fuel needed to perform for events lasting over 90 minutes.
Best Foods for Carb Loading
Instead of chips, focus on these easily digestible, carbohydrate-rich foods:
- Low-fiber grains: White pasta, white rice, white bread, and bagels.
- Starchy vegetables: Peeled potatoes and sweet potatoes without heavy, high-fat toppings.
- Fruits: Bananas, applesauce, and fruit juice are low in fiber and easy on the stomach.
- Sports Drinks and Gels: Liquid carbohydrates are an easy way to meet high intake requirements without feeling overly full.
- Low-fat dairy: Low-fat yogurt and milk can contribute to your carbohydrate goals.
Comparison of Carb Loading Foods
| Feature | Chips | Ideal Carb Loading Foods (e.g., White Rice, Pasta) |
|---|---|---|
| Fat Content | High | Low |
| Fiber Content | Generally Low (Refined), but can contain some | Low (when processed) to moderate (when whole) |
| Energy Release | Quick spike, not sustained | Gradual, sustained energy |
| Nutrient Density | Low | Higher (especially whole grains) |
| GI Distress Risk | High (due to fat) | Low (when choosing low-fiber options) |
| Glycogen Storage | Inefficient (due to high fat) | Efficient |
Practicing Your Race Day Nutrition
It is critical to practice your carb-loading strategy during your long training runs. This allows you to test what foods and quantities your body tolerates best and helps you become comfortable with the feeling of fuller glycogen stores. It also prevents any unpleasant surprises on the day of the event.
Conclusion: Prioritize the Right Carbs, Not Just Any Carbs
While chips contain carbohydrates, their high-fat content makes them a poor choice for carb loading. This nutritional strategy requires a focus on high-carbohydrate, low-fat, and low-fiber foods to efficiently maximize glycogen stores without causing digestive issues. By choosing options like white rice, pasta, and bananas and practicing your nutrition plan during training, you can ensure your body is properly fueled for peak performance on race day.

How to properly carb load for endurance events
- Start two to three days before: Begin increasing carbohydrate intake while decreasing training volume 2-3 days before the event.
- Eat familiar foods: Stick to foods you've tested in training to minimize the risk of GI issues.
- Reduce fat and fiber intake: Prioritize low-fiber and low-fat carbohydrate sources to maximize glycogen storage and prevent stomach problems.
- Consider liquid calories: If you struggle to eat enough food, incorporate sports drinks, juice, or smoothies to hit your carbohydrate target.
- Stay hydrated: Drink extra fluids, as carbohydrates are stored with water in the muscles.
