The study will also investigate metabolic responses to prolonged fasting and whether these responses are influenced by exercise.\n\nParticipant Population\u002FHealth Conditions: The study will involve adults attending the Buchinger Wilhelmi Clinic who undergo the prolonged fasting program and meet the study eligibility criteria.\n\nMain Questions:\n\n* Does structured exercise performed before and\u002For during prolonged fasting enhance its effects on physical fitness, body composition, and cardiometabolic health?\n* Does structured exercise improve sleep quality and health-related quality of life during prolonged fasting?\n\nParticipants Will:\n\n* Undergo the Buchinger Wilhelmi prolonged fasting program.\n* Choose whether to complete an online exercise program before the clinical stay and\u002For a supervised exercise program during fasting.\n* Undergo physiological, physical fitness, and body composition assessments before and after the intervention.\n* Provide blood samples to assess cardiometabolic and metabolic responses.\n* Complete assessments of sleep and health-related quality of life.\n\nComparison Groups: Researchers will compare the four study conditions to determine whether structured exercise performed before and\u002For during prolonged fasting enhances the physiological, metabolic, and functional effects of the Buchinger Wilhelmi fasting program.",[29,30],"Fasting Conditions","Metabolic Health",[32,33,34,35,36],"Prolonged fasting","Buchinger Wilhelmi fasting","Physical exercise","Cardiometabolic health","Physical fitness","NOT_YET_RECRUITING","2026-09-23",{"date":40,"type":41},"2026-09-29","ACTUAL",{"date":43,"type":23},"2027-01",{"date":45,"type":23},"2030-01",{"name":47,"class":48},"Universidad de Almeria","OTHER"]
