- Abstract
- The human body utilises a mixture of two substrates for energy metabolism under most physiological conditions - glucose and fatty acids. As the fasting state progresses, lipolysis increases and free fatty acids are utilised as the main energy source. However, research has suggested a large inter-individual requirement of substrate utilization (SU) during fasting. The aim of the research is to identify if there is a relation between body composition, preferred SU order and ratio and hunger perception after a 14-hour overnight fast. The current study measured the energy expenditure, body composition and anthropometric values of seventeen healthy males with average parameters being: age of 26 years, height 178 cm, weight 77 kg, 16% body fat, 84 % lean mass and BMI of 24.3. Participants were measured one day before the fast, while consuming their normal diet, in the morning (visit 1), in the afternoon (visit 2) and finally in the morning of the next day, after a 14-hour overnight fast (visit 3). Hunger perception was measured with a visual analogue scale at visits 1 and 3 and the results showed no statistical effect of time on both metabolic parameters and body composition parameters. There was a significant increase in carbohydrate (CHO) oxidation rates during visit 2 of 0.451 ± 0.256 g/min compared to 0.280 ± 0.114 g/min and 0.256 ± 0.110 g/min during visits 1 and 3 respectively. However, no significant difference in the relative contribution of CHO oxidation to overall energy expenditure (69.7 ± 56.9%, 67.8 ± 44.2 % and 56.5 ± 32.0% for visits 1, 2 and 3 respectively, p=0.075). Results also show a significant effect of time on appetite perception across participants, increasing after fasting. This research showed no major differences in SU and body composition observed in the sample study.
