Brief Summary

Type 2 diabetes is the most common metabolic disease worldwide, characterized by hyperglycemia, decreased whole body insulin sensitivity, and white adipose tissue (WAT) dysfunction. A key factor in its development is chronic overnutrition, usually with a high-fat diet (HFD), leading to disturbances of glucose and lipid metabolism. However, the mechanism of short-term HFD-induced tissue-specific insulin resistance remains poorly understood. This project aims to further unravel the underlying mechanisms of short-term HFD overnutrition-mediated WAT insulin resistance. The model described here corresponds to a randomized, single- blinded parallel-grouped trial, consisting of two interventions: a macronutrient-balanced diet and or a hypercaloric diet over three weeks in order to investigate differences in interorgan fatty acid and glucose metabolism between the studied groups. Based on recent studies, the hypothesis is that 21-day hypercaloric HFD induces WAT insulin resistance via a diacylglycerol, novel protein kinase C-insulin receptor signaling model in both fasting and insulin-stimulated states.
