AMP-activated protein kinase (AMPK) is an important enzyme that plays a critical role in cellular energy metabolism. By activating AMPK through diet, lifestyle, and supplement strategies, individuals can improve their glucose and lipid metabolism, promote mitochondrial function and autophagy, and protect against oxidative stress and inflammation through activities of AMPK. However, it is important to point out that while AMPK activation can be beneficial for health, it should not be viewed as the only solution to prevent or treat disease. A comprehensive approach to health includes a healthy diet, regular exercise, stress management, and regular medical checkups. These are necessary to achieve good health and wellbeing. The aim of this review is to provide a broad overview of some of the more recent developments within the AMP-activated protein kinase (AMPK) field. Here, a number of recent breakthroughs in the mechanistic understanding of AMPK function have been reviewed.  The AMP-activated protein kinase (AMPK) acts as a cellular metabolic sensor. When activated by increases in cellular AMP, it promotes energy restoration and inhibits energy consumption. It coordinates the changes in the activity of enzymes of lipid metabolism and regulates the partitioning of fatty acid between oxidative and biosynthetic pathways. When activated, AMPK initiates metabolic changes like increased glucose uptake, fatty acid oxidation, and glycogen breakdown to generate ATP while inhibiting processes like protein synthesis and lipid synthesis that consume energy. Furthermore, the review suggested that there are several diet, lifestyle, and supplement strategies that can help to better activate AMPK. A low-carbohydrate diet has been shown to activate AMPK and improve glucose and lipid metabolism. Obesity and the metabolic syndrome are a major health problem in Western and developing countries. Keeping in view the role of AMPK in regulating energy balance at both the cellular and whole-body levels, this kinase occupies a central position in studies regarding obesity and diabetes. The study concluded that due to its role in regulating lipid metabolism, AMPK is a potential therapeutic target for conditions like obesity and metabolic syndrome, where dysregulation of lipid metabolism contributes to disease progression. Further research suggests that AMPK may play a role in protecting neurons from stress-induced damage, making it a potential target for neurodegenerative conditions.
