This flexibility plays an important role in an individual's health because losing it increases the risk of obesity, metabolic syndrome, insulin resistance, and type 2 diabetes. Considering that humans spend most of their awakening hours in a postprandial (PP) state, an organism's metabolic flexibility (MF) to respond to a standardized meal's consumption would provide information on the individual's metabolic health. The PP response to glucose following an oral glucose tolerance test or consumption of a high-carbohydrate meal is well described; however, few studies assess the FM and PP metabolome using mixed meals with different macronutrients. The investigators address how metabolic flexibility and metabolome change after consuming standardized meals with different macronutrient ratios. Data collection includes clinical and diet information, indirect calorimetry, and capillary blood sampling during fasting and after consumption of standardized meals. Samples are collected weekly for one month. The data will determine the metabolic flexibility and metabolome after consuming standardized meals with different macronutrient ratios.",[93,94,95,96,97],"Fasting","Postprandial Hyperglycemia","Lipid Metabolism Disorders","Glucose Metabolism Disorders","Insulin Sensitivity",[99,100,101],"metabolic flexibility","postprandial response","mixed meals","2025-03-10",{"date":104,"type":105},"2025-03-17","ACTUAL",{"date":107,"type":105},"2024-01-08",{"date":109,"type":87},"2026-12-18",{"name":5,"class":6},1]
