What Science Says About Your Carb Tolerance

What Is Carbohydrate Intolerance?

Carbohydrate intolerance (CICO) is defined as the inability to tolerate or metabolize carbohydrates. People with CICO are unable to consume enough carbohydrates to meet their daily energy needs without experiencing symptoms such as hunger, nausea, vomiting, fatigue and/or diarrhea. They may experience these symptoms even when they’re not hungry or have no desire for food at all.

People with CICO are usually diagnosed after they’ve been following a low-carb diet plan for several months. Some people don’t realize that they have CICO until it’s too late, but most will eventually seek medical attention if they continue to experience symptoms.

The term “metabolism” refers to the process by which carbohydrates are broken down into glucose, fat and other substances in our bodies. If your body doesn’t break down carbohydrates properly, then you won’t get enough energy from them.

How Does Carbohydrate Intolerance Affect Me?

If you have CICO, you’ll probably feel hungry less often than someone else eating the same amount of calories. You might eat fewer meals per day and still end up consuming the same number of calories each time because your body will just store those extra calories as fat instead of using them for energy.

Even though you’re eating more than enough food, you’ll still feel tired and fatigued due to a lack of energy. Your body can’t run efficiently on “empty,” so the next time you eat you might experience stomach cramps, diarrhea, nausea and other embarrassing symptoms.

Why Do I Have CICO?

CICO is a complex condition caused by a combination of factors.
