High blood sugar levels can cause significant damage long before diabetes is diagnosed: they attack blood vessels and nerves, accelerate aging, and contribute to obesity as well as serious illnesses. The dangerous part is that most affected individuals are unaware of this and thus put their health at risk. Today, one in five adults suffers from pre-diabetes. Even seemingly healthy individuals can be affected, as elevated sugar levels often go unnoticed in a doctor's office at first. However, type 2 diabetes and its precursors can be prevented, alleviated, and even cured early on with the right diet. Germany's leading nutritional physician and diabetologist, nutrition expert Matthias Riedl, demonstrates how anyone can improve their glucose management in just four weeks to become fitter, slimmer, and healthier. By following a few simple rules, one can keep blood sugar levels stable without having to give up anything. Practical recipes and numerous helpful tips support the program.
