What is konjac?
Konjac, or amorphophallus konjac, is a perennial plant that grows in the tropical and subtropical regions of Southeast Asia, notably in China, Japan, Korea, Indonesia, and Vietnam. It is a tuberous rhizome, meaning an underground stem that can weigh up to 4 kg and is edible. Konjac is mainly composed of glucomannan, a soluble fiber that can absorb up to 100 times its weight in water. Konjac also contains starch, water, proteins, lipids, minerals, and vitamins, notably vitamin B6
.
Glucomannan, the key to konjac’s effectiveness
Glucomannan is the active substance in konjac, the one that gives it its exceptional properties for weight loss. It is a soluble dietary fiber that forms a viscous gel when it comes into contact with water. This gel occupies a large volume in the stomach and intestines, which causes a lasting feeling of fullness and reduces appetite. Glucomannan also slows gastric emptying and the passage of nutrients into the bloodstream, which promotes the regulation of blood sugar and cholesterol. Finally, glucomannan stimulates intestinal transit and facilitates the elimination of waste and toxins.
The other components of konjac
In addition to glucomannan, konjac contains other elements that contribute to its nutritional value. Starch is a source of energy for the body, which can be used during physical or mental exertion. Water helps maintain good hydration and prevent dehydration. Proteins are essential for the growth and repair of muscle tissues. Lipids are necessary for the proper functioning of cells and hormones. Minerals are involved in many physiological processes, such as acid-base balance, muscle contraction, or nerve transmission. Vitamin B6 contributes to the metabolism of carbohydrates, lipids, and proteins, as well as the synthesis of hemoglobin.
How does konjac help you lose weight?
Konjac is a valuable ally for weight loss, provided it is combined with a balanced diet and regular physical activity. It acts at several levels to promote weight loss:
It reduces calorie intake
Konjac is a very low-calorie food, since it contains only 9.6 kcal per 100 g. It can therefore advantageously replace other foods higher in calories, such as rice, pasta, or bread. Moreover, konjac increases satiety and reduces the desire to snack between meals, which limits total calorie intake. According to a study conducted in 2005, consuming 3 g of glucomannan per day for 8 weeks reduced energy intake by 17% in obese subjects.
It promotes fat burning
Konjac also has a positive effect on fat metabolism. Indeed, it reduces the absorption of sugars and lipids at the intestinal level, which limits their storage as fat. It also promotes the use of fats as an energy source, which increases energy expenditure. According to a study conducted in 2008, consuming 3 g of glucomannan per day for 12 weeks reduced body weight, body mass index, waist circumference, and fat percentage in overweight subjects.
It improves cardiovascular health
Konjac also has beneficial effects on cardiovascular health, which is important to prevent complications related to obesity. It helps lower total cholesterol, bad cholesterol (LDL), and triglycerides, while increasing good cholesterol (HDL). It also helps regulate blood sugar and prevent type 2 diabetes. According to a meta-analysis conducted in 2008, glucomannan consumption significantly reduced total cholesterol, LDL cholesterol, triglycerides, and fasting blood sugar in subjects at high cardiovascular risk.
