Dietary Fat Oxidation

This study compared 24-h nutrient oxidation responses between a sedentary condition (SED) and a condition in which short 5-min bouts of moderate-intensity physical activity were performed hourly for nine consecutive hours over 4 days (MICRO). To determine whether any shifts in fuel use were due solely to increases in energy expenditure, we also studied a condition consisting of a single isoenergetic 45-min bout of moderate-intensity exercise (ONE). Twenty sedentary overweight or obese adults (10 men/10 women; 32.4 ± 6.3 yr; BMI, 30.6 ± 2.9 kg/m2) completed all three conditions (MICRO, SED, and ONE) in a randomized order. Each condition consisted of a 3-day free-living run-in followed by a 24-h stay in a whole-room calorimeter to measure total energy expenditure (TEE) and substrate utilization. Dietary fat oxidation was also assessed during the chamber stay by administering a [1-13C] oleic acid tracer at breakfast. Energy intake was matched across conditions. Both MICRO and ONE increased TEE relative to SED, resulting in a negative energy balance. HOMA-IR improved in both activity conditions. MICRO increased 24-h carbohydrate oxidation compared with both ONE and SED ( P < 0.01 for both). ONE was associated with higher 24-h total fat oxidation compared with SED, and higher 24-h dietary fat oxidation compared with both SED and MICRO. Differences in substrate oxidation remained significant after adjusting for energy balance. In overweight and obese men and women, breaking up sitting time increased reliance upon carbohydrate as fuel over 24 h, while a single energy-matched continuous bout of exercise preferentially relies upon fat over 24 h. NEW & NOTEWORTHY Insulin sensitivity, as assessed by HOMA-IR, was improved after 4 days of physical activity, independent of frequency and duration of activity bouts. Temporal patterns of activity across the day differentially affect substrate oxidation. Frequent interruptions of sedentary time with short bouts of walking primarily increase 24-h carbohydrate oxidation, whereas an energy-matched single continuous bout of moderate intensity walking primarily increased 24-h fat oxidation.

Abstract. Using a mouse model long-term selected for high body mass (DU6i), we investigated if their higher degree of body fat as compared to unselected controls (DUKsi) was due to a greater fat accumulation, attributable to differences in substrate oxidation in response to a higher fat intake. We measured energy expenditure (EE) and substrate oxidation by indirect calorimetry at the ages of 42 d and 98 d in response to a fat rich diet compared to a standard diet (F, 20 %; C, 5 % fat) introduced at weaning (21 d). The EE to food energy intake ratio (Q) was calculated and uncoupling protein (UCP1) mRNA expression was analysed in brown adipose tissue in male mice of both strains. The F diet increased body and fat mass in DU6i (P<0.05) but not in DUKsi. Energy intake was not influenced by diet in both strains, but EE was lower in DU6i than in controls (P<0.05). In contrast to DU6i, fat oxidation was higher in DUKsi mice fed the F diet until the age of 42 d (P<0.05). At the age of 42 d, the Q value was lower in DU6i, and higher with F diet irrespective of strain. UCP1 mRNA expression was twice as high in DUKsi as in DU6i (P<0.05). Between 42 d and 98 d of age, DU6i mice were more susceptible to body mass gain and fat deposition in response to the F diet due to insufficient increase in fat oxidation and energy expenditure possibly related to lower UCP1 mRNA expression.

Dietary Fat Oxidation

When using 13C tracer to measure plasma fat oxidation, an acetate recovery factor should be determined in every subject to correct for label sequestration. Less is known regarding the acetate recovery factor for dietary fatty acid oxidation. We compiled data from six studies to investigate the determinants of the dietary acetate recovery factor (dARF) at rest and after physical activity interventions and compared the effects of different methods of dARF calculation on both the fat oxidation and its variability. In healthy lean subjects, dARF was 50.6 ± 5.4% dose ( n = 56) with an interindividual coefficient of variation of 10.6% at rest and 9.2% after physical activity modifications. The physical activity interventions did not impact dARF, and the intraindividual coefficient of variation was 4.6%. No major anthropological or physiological determinants were detected except for resting metabolic rate, which explains 7.4% of the dARF variability. Applying an individual or an average group dARF did not affect the mean and the variability of the derived dietary lipid oxidation at rest or after physical activity interventions. Using a mean dARF for a group leads to over- or underestimation of fat oxidation of less than 10% in individual subjects. Moreover, the use of a group or individual correction did not affect the significant relationship found between fasting respiratory exchange ratio and dietary fat oxidation. These data indicate that an average dARF can be applied for longitudinal and cross-sectional studies investigating dietary lipid metabolism.
