Abstract
- Introduction: Sleep disorders, alone or in association with a high-calorie diet, may determine metabolic changes in the autonomic nervous system and in the hypothalamic-pituitary-adrenal axis, which may increase glycemia and produce glucose intolerance. The state of glucose intolerance usually precedes the onset of type 2 diabetes. Objective: This study aims to evaluate the effects of the association of paradoxical sleep deprivation and hypercaloric diet on the eating behavior and glucose tolerance of mice. Methods: Swiss mice were distributed into six groups: (1) control; (2) hypercaloric diet; (3) paradoxical sleep deprivation; (4) paradoxical sleep deprivation + hypercaloric diet; (5) monossodium glutamate (PSP); and (6) paradoxical sleep deprivation + monossodium glutamate. During the eight-week follow-up, food consumption was assessed and mice were weighed periodically. Sleep deprivation was performed weekly. After eight weeks, the oral glucose tolerance (TTGO) and insulin sensitivity test (TTI) were performed. At the end, heart and epididymal fat were weighed. Results: There was a significant increase in body weight in obese mice, which was associated with increased visceral fat content. All animals, obese and PSP, showed worsening in the parameters that measured the glucose metabolism, either on TTGO and TTI. There was no change in cardiac weight. Conclusion: The administration of a hypercaloric diet and paradoxical sleep deprivation determine glucose intolerance and insulin resistance, which in this work was not synergistic.
