Abstract
Prediabetes is characterized by impaired glucose uptake and insulin sensitivity in the muscle, as well as a significant risk of developing diabetes, chronic renal disease, cardiovascular disease, and death. A definite bidirectional connection exists between pre-diabetes, diabetes, and NAFLD. The presence of NAFLD is associated with the subsequent development of new-onset type 2 diabetes (T2DM). There was a 6-fold rise in new-onset diabetes in people whose fatty liver severity progressed from mild to moderate or severe over 5 years, and a decrease in T2DM incidence comparable to that in those without steatosis. Insulin resistance is a common pathophysiological mechanism across metabolic illnesses, including prediabetes, diabetes, and NAFLD. As a result, better names for metabolically linked metabolic fatty liver disease have been considered.
Lifestyle is the cornerstone of treatment for patients with prediabetes, T2DM, and NAFLD. Several significant randomized controlled trials show that a customized low-calorie meal plan and behavioral change are highly effective in preventing or delaying prediabetes, type 2 diabetes, and improving other cardiometabolic markers (such as blood pressure, lipids, and inflammation). Several drugs already approved for the treatment of prediabetes and diabetes are beneficial for NAFLD/NASH.

Key words: Prediabetes, diabetes mellitus, non-alcoholic fatty liver disease, NAFLD.
