The importance of AMPK in obesity and chronic diseases and the relationship of AMPK with nutrition: a literature review.

This review will examine the role of 5'-adenosine monophosphate-activated protein kinase (AMPK) in the treatment of obesity, medical nutrition and chronic diseases, and its relationship with nutrition. In the literature, the number of studies examining the direct relationship of AMPK with nutrition is negligible. For this reason, information on the subject has been compiled from all the studies that can be accessed by searching the terms AMPK and disease, AMPK and health, AMPK and exercise, AMPK and nutrition. It can be stated that AMPK is inhibited in many pathological conditions such as inflammation, diabetes, aging and cancer, and AMPK activation has positive effects in many diseases such as insulin resistance, diabetes, obesity, cancer and Alzheimer's. When the relationship between nutrition and AMPK is examined, it is seen that food intake inhibits AMPK, but especially high-carbohydrate and fatty diets are more effective at this point. In addition, high fructose corn sirup and long chain saturated fatty acids increased by consumption of industrial foods and frequent meals appear to be an inactivator for AMPK. For AMPK activation in medical nutrition therapy, it is recommended to use methods such as evening fasting and intermittent fasting, taking into account the human circadian rhythm.

The effect of obesity on metabolic parameters: a cross sectional study in adult women.

Background: In this study conducted in adult healthy women, it was aimed to determine the relationship between anthropometric measurements such as Body Mass Index (BMI), waist circumference, waist/height ratio and blood parameters, which are used to define obesity. Methods: A total of 90 women, with a mean age of 38.4±8.8 years, 34 pre-obese between BMI: 25.0-29.9 kg/m2 and 56 obese BMI: ≥30.0 kg/m2, participated in the study. Results: According to plasma atherogenic index (PAI), women with high cardiovascular risk had lower high-density lipoprotein (HDL) values, while low-density lipoprotein (LDL), triglyceride (TG), aspartate transaminase (AST) values were found to be higher (p<0.05). It was observed that obese women according to BMI had higher fasting glucose, TG, alanine transaminase (ALT), AST and urea values, and lower HDL and mean erythrocyte volume (MCV) values compared to pre-obese women (p<0.05). A moderately positive relationship was found between body fat percentage, waist circumference and waist/height ratio and fasting glucose and ALT levels of women, and a moderate negative relationship was found between vitamin D levels (p<0.05). Conclusions: It is understood that the increase in body fat tissue, especially in the abdominal region, in adult healthy women has negative effects on blood parameters and the risk of developing chronic diseases will decrease by preventing this situation.
