Diet Induced Thermogenesis And Metabolic Rate

Generally the hierarchy in macronutrient oxidation in the postprandial state is reflected similarly in diet induced thermogenesis with the sequence alcohol protein carbohydrate and fat.

Diet induced thermogenesis and metabolic rate. Resting metabolic rate and diet induced thermogenesis in young and elderly subjects. Daily energy expenditure consists of three components. The variability in resting metabolic rate rmr diet induced thermogenesis dit and fuel utilization rates as well as the impact of several factors on rmr and dit were assessed in several studies with a total of 103 males and females. Brown adipose tissue bat has long been recognized as the major site of non shivering thermogenesis nst during cold exposure cold induced thermogenesis cit and arousal from hibernation in small rodents since the rediscovery of metabolically active bat using fluorodeoxyglucose fdg positron emission tomography pet and computed tomography ct in adult humans 2 5.

The intraindividual cv of rmr and respiratory quotients was 5 6. Measuring conditions include nutritional status of the subject physical activity and duration of the observation. Relationship with body composition fat distribution and physical activity level.
