Thermic Effect

The resting metabolic rate (RMR) and thermic effects (TEF) of a sucrose-sweetened soft drink in a group (n = 19) of ovulating young Chinese women were determined by indirect calorimetry in the midfollicular and midluteal phases of the menstrual cycle. Urinary luteinizing hormone surge was used to confirm ovulation. The RMR was measured twice in each phase and found to be similar (F(1,18) = 0.863) across the follicular (5018 kJ/24 h) and the luteal (5098 kJ/24 h) phases. Within each phase and on separate days, subjects were given water (280 mL) or sucrose-sweetened soft drink (539 kJ). Soft drink, but not water, consumption increased energy expenditure over a period of 45 min. Compared with the follicular phase, a small but significant increase in TEF (kJ/45 min) was observed in the luteal phase (t = 2.434, p < 0.05). Energy expenditure after drinking the soft drink, however, was similar in the two phases. RMR was positively correlated with TEF (r = 0.613, p < 0.01) and net TEF (r = 0.648, p < 0.005) in the luteal but not the follicular phase. In ovulating women, the thermic effect of sucrose is influenced by the phase of the menstrual cycle.Key words: menstrual cycle, resting metabolic rate, thermic effect of food, sucrose, Chinese women.

Thermic Effect

The resting metabolic rate (RMR) and thermic effect of a meal (TEM) were determined in 13 low-energy intake (LOW) and 11 adequate-energy intake (ADQ) male endurance athletes. The LOW athletes reported eating 1,490 kcal·day-1less than the ADQ group, while the activity level of both groups was similar. Despite these differences, both groups had a similar fat-free mass (FFM) and had been weight stable for at least 2 years. The RMR was significantly lower (p<0.05) in the LOW group compared to the values of the ADQ group (1.19 vs. 1.29 kcal·FFM-1·hr-l, respectively); this difference represents a lower resting expenditure of 158 kcal·day-1. No differences were found in TEM between the two groups. These results suggest that a lower RMR is one mechanism that contributes to weight maintenance in a group of low- versus adequate-energy intake male athletes.

Thermic Effect

The impact of alcohol (ethanol) on resting energy expenditure of male non-obese volunteers was determined in two studies. In the first study the thermic effect of alcohol on resting metabolic rate (RMR) was assessed in ten male non-obese volunteers. In the second study the impact of alcohol on diet-induced thermogenesis (DIT) was determined in twelve male non-obese volunteers. Energy expenditure was measured with a ventilated-hood system. RMR was measured for 60 min with the subjects in a fasting state. In the first study subjects received in random order 20 g alcohol in concentrations of 75, 180 and 300 ml/I water respectively. After measurement of the RMR the thermic effect of alcohol was measured for 90 min. In the second study volunteers received in random order and in duplicate either a meal of food (2 MJ) plus an alcoholic aperitif (20 g alcohol in a 180 ml/1 solution) or an isoenergetic meal of food alone (2.55 MJ) plus a placebo aperitif containing no alcohol. DIT was measured for 240 min. Alcohol induced a significant thermic effect, which varied between 0.22 and 0.30 kJ/min. No systematic difference in DIT was observed among the different concentrations. DIT was not significantly affected by the ingestion of alcohol. Total DIT was 219 (SE 14) kJ for the alcohol treatment and 185 (SE 20) kJ for the control treatment. The results do not support the suggestion that alcohol is less efficiently used as an energy source in comparison with, for example, fats and carbohydrates.

To clarify further the independent relationships of body composition parameters to energy expenditure, resting metabolic rate (RMR) and postprandial thermogenesis were studied in four groups who were matched for absolute fat mass (study 1) and relative fatness (study 2). In study 1, five lean [group A, 15.4 +/- 0.6% (+/- SE) body fat] and five obese men (group B, 25.0 +/- 0.9% fat) were matched on body fat mass (13.0 +/- 0.9 vs. 14.4 +/- 0.8 kg, respectively). Fat-free mass (FFM) and total weight were greater for group A than B. RMR was measured for 3 h in the fasted state and after a 720-kcal mixed meal. RMR was greater for group A than B (1.38 +/- 0.08 vs. 1.14 +/- 0.04 kcal/min, P less than 0.05). The thermic effect of food, calculated as 3 h postprandial minus fasting RMR, was greater for group A than B (65 +/- 6 vs. 23 +/- 9 kcal/3 h; P less than 0.05). In study 2, two groups (n = 6 men/group) were matched for percent body fat (33 +/- 1% fat for both) but differed in lean, fat, and total weights: 50.8 +/- 3.1 kg FFM for the lighter (group C) vs. 68.0 +/- 2.8 kg FFM for the heavier (group D) group, P less than 0.05. RMR was lower for group C than D (1.17 +/- 0.06 vs. 1.33 +/- 0.04 kcal/min, P less than 0.05), but the thermic effect of food was not significantly different (31 +/- 3 vs. 20 +/- 6 kcal/3 h).(ABSTRACT TRUNCATED AT 250 WORDS)

Thermic Effect

Ballet dancers may be at risk of eating disorders, and women with eating disorders are at increased risk for menstrual dysfunction. Caloric intakes of amenorrheic dancers have been reported to be less than those of eumenorrheic dancers, indicating a possible conservation of energy. We evaluated resting metabolic rate and the thermic effect of food following ingestion of a 500-kcal liquid supplement in 8 amenorrheic dancers and 10 eumenorrheic dancers. Body fat was higher for the eumenorrheic group (20%) than the amenorrheic group (15%). Resting metabolic rate did not differ between groups when corrected for body mass (24.2 ± 1.1 kcal/kg/day for amennorheic dancers vs. 25.0 ± 0.9 kcal/kg/day for eumennorheic dancers), nor did resting metabolic rate differ when adjusted for lean mass. However, amennorheic dancers expended significantly less energy post-prandially once adjusted for lean mass (ANOVA, effect of group p = 0.035). Dancers were asked to complete the Eating Disorder Inventory, a self-report scale that measures symptoms of disordered eating; 9 of 10 eumennorheic but only 4 of 8 amennorheic women were willing to complete the questionnaire. Eumennorheic dancers had profiles similar to or less pathologic than those of non-eating-disordered populations. Greater dissatisfaction was expressed by eumennorheic women as body fat increased. Contrary to the findings in previous studies, amennorheic ballet dancers did not exhibit energy conservation via reductions in resting metabolic rate but did expend slightly less energy in thermic effect of food compared to normally menstruating women.

Abstract Context Daily variation in thermic effect of food (TEF) is commonly reported and proposed as a contributing factor to weight gain with late eating. However underlying circadian variability in resting metabolic rate (RMR) is an overlooked factor when calculating TEF associated with eating at different times of the day. Objective To determine whether methodological approaches to calculating TEF contribute to the reported phenomena of daily variation in TEF. Design, Setting and Participants: Fourteen overweight to obese but otherwise healthy subjects, had their resting and postprandial energy expenditure measured over 15.5 hours at a clinical research unit. TEF was calculated for breakfast, lunch and dinner using standard methods (above a baseline and premeal RMR measure) and compared to a method incorporating a circadian RMR where RMR was derived from a sinusoid curve model and TEF was calculated over and above the continuously changing RMR. Main Outcome measures TEF at breakfast, lunch and dinner calculated with different methods. Results Standard methods of calculating TEF above a premeal measured RMR showed that morning TEF [60.8kcal ± 5.6] (mean ± SEM) was 1.6 times greater than TEF at lunch [36.3kcal ± 8.4], and 2.4 times greater than dinner TEF [25.2kcal ± 9.6] (p=0.022). However, adjusting for modelled circadian RMR nullified any differences between breakfast [54.1kcal ± 30.8], lunch [49.5kcal ± 29.4], and dinner [49.1kcal ± 25.7] (p=0.680). Conclusions Differences in TEF between morning and evening can be explained by underlying circadian resting energy expenditure, which is independent of an acute effect of eating.

Thermic Effect

This study examined resting metabolic rate (RMR) and thermic effect of a meal (TEM) among athletes who had participated in long-term anaerobic or aerobic exercise. Nine collegiate wrestlers were matched for age, weight, and fat-free weight with 9 collegiate swimmers. Preliminary testing included maximal oxygen consumption, maximal anaerobic capacity (MAnC) for both the arms and the legs, and percent body fat. On two separate occasions, RMR and TEM were measured using indirect calorimetry.was significantly higher in the swimmers while MAnC was significantly higher in the wrestlers for both the arms and the legs. RMR adjusted for fat-free weight was not significantly different between groups. The differences in total and percentage of TEM between the groups were not statistically significant, and there were no differences in baseline thyroid hormones. These data suggest that despite significant differences inand WAnT values following long-term aerobic and anaerobic exercise training, resting energy expenditure does not differ between these college athletes.
