The endocrinologist Atrakhov says that complete abstinence from sugar can lead to metabolic failure of the body:
Recent studies in the field of diabetes have shown paradoxical results. Those who decided to completely eliminate sugar from the menu developed signs of insulin resistance, deteriorated the natural control of blood sugar levels and developed fatty liver disease. With an extreme lack of glucose, the metabolism tries to compensate for it and is rebuilt, which causes a deterioration in health indicators.
In addition to metabolic failure, such a restriction can cause problems in the digestive system: sugar is necessary to feed microorganisms, and without it, the number of beneficial bacteria in the intestines decreases sharply and inflammatory strains multiply, which can lead to chronic systemic diseases.
