Why is Konjac So Low in Calories?

Konjac, a plant native to Southeast Asia, is often celebrated for its incredibly low-calorie content. But why is konjac so low in calories? The answer lies in its unique composition and the way it interacts with our bodies.

Composition of Konjac

Konjac is primarily composed of water and a type of dietary fiber called glucomannan. Glucomannan is a water-soluble polysaccharide that has several properties contributing to konjac's low-calorie profile.

  1. High Water Content: Konjac products, such as konjac rice and noodles, are made by mixing konjac flour with water. This process results in a food product that is approximately 97% water. The high water content significantly reduces the caloric density of konjac products.

  2. Rich in Fiber: The primary fiber in konjac, glucomannan, is a non-digestible carbohydrate. Since glucomannan is not broken down and absorbed by the body, it does not contribute calories in the way that digestible carbohydrates, proteins, and fats do. Instead, it passes through the digestive system largely intact, providing bulk without adding calories.

How Glucomannan Contributes to Low Calories

Glucomannan's properties explain why konjac is so low in calories:

  1. Low Digestibility: Unlike other carbohydrates that are broken down into sugars and absorbed into the bloodstream, glucomannan resists digestion. This resistance means that it provides minimal calories as it moves through the gastrointestinal tract.

  2. Satiety and Fullness: When glucomannan comes into contact with water, it expands and forms a gel-like substance. This expansion not only gives konjac products their unique texture but also promotes a feeling of fullness. As a result, konjac can help reduce overall calorie intake by curbing appetite and preventing overeating.

  3. Minimal Nutrient Absorption: The gel-like nature of glucomannan can slow down the absorption of other nutrients, further contributing to the low-calorie content of konjac. This characteristic makes konjac particularly appealing for those looking to manage weight and blood sugar levels.

Nutritional Comparison

To put konjac's low-calorie content in perspective, consider the caloric values of common foods:

  • Konjac Rice: Approximately 10-20 calories per 100 grams

  • White Rice: Approximately 130 calories per 100 grams

  • Brown Rice: Approximately 110 calories per 100 grams

The significant difference in caloric content highlights why konjac is a favored option for calorie-conscious individuals.


Konjac's low-calorie nature is primarily due to its high water content and the presence of glucomannan, a non-digestible, water-soluble fiber. These factors make konjac an excellent food choice for those seeking to reduce caloric intake, manage weight, and maintain a healthy diet. Its ability to promote fullness and slow nutrient absorption further enhances its appeal as a low-calorie food option.
