Previous studies have shown effects of high-protein diets, especially whey protein, on energy expenditure and satiety, yet a possible distinction between the effects of whey or α-lactalbumin has not been made. The present study assessed the effects of the addition of total whey protein (whey) or caseinomacropeptide-depleted α-lactalbumin-enriched whey protein (α-lac) to a breakfast yoghurt drink on energy expenditure and appetite suppression in human subjects. A total of eighteen females and seventeen males (aged 20·9 (sd 1·9) years; BMI 23·0 (sd 2·1) kg/m2) participated in an experiment with a randomised, three-arm, cross-over design where diet-induced energy expenditure, respiratory quotient and satiety were measured. Breakfasts were isoenergetic and subject-specific: a normal-protein (NP) breakfast consisting of whole milk (15, 47 and 38 % energy from protein, carbohydrate and fat, respectively), a high-protein (HP) breakfast with additional whey or a HP breakfast containing α-lac (41, 47 and 12 % energy from protein, carbohydrate and fat, respectively). Resting energy expenditure did not differ between the three conditions. HP breakfasts (area under the curve: whey, 217·1 (se 10·0) kJ × 4 h; α-lac, 234·3 (se 11·6) kJ × 4 h; P < 0·05) increased diet-induced thermogenesis more compared with a NP yoghurt at breakfast (179·7 (se 10·9) kJ × 4 h; P < 0·05). Hunger and desire to eat were significantly more suppressed after α-lac (hunger, − 6627 (se 823); desire to eat, − 6750 (se 805) mm visual analogue scale (VAS) × 4 h; P < 0·05) than after the whey HP breakfast (hunger, − 5448 (se 913); desire to eat, − 5070 (se 873) mm VAS × 4 h; P < 0·05). After the HP breakfasts, a positive protein balance occurred (α-lac, 0·35 (sd 0·18) MJ/4 h; whey, 0·37 (sd 0·20) MJ/4 h; P < 0·001); after the NP breakfast a positive fat balance occurred (1·03 (sd 0·29) MJ/4 h; P < 0·001). In conclusion, consumption of a breakfast yoghurt drink with added whey or α-lac increased energy expenditure, protein balance and decreased fat balance compared with a NP breakfast. The α-lac-enriched yoghurt drink suppressed hunger and the desire to eat more than the whey-enriched yoghurt drink.

The aim of this study was to investigate the effect of Hibiscus sabdariffa tea on energy expenditure, satiety response and food intake. This is an open-label, crossover, randomized clinical trial (RBR-5HZ86T), including 21 subjects (11 women, 10 men). The individuals were evaluated at acute moments (fasting and after eating standardized breakfast accompanied by water or Hibiscus sabdariffa tea). Resting energy expenditure was measured by indirect calorimetry, subjective satiety responses were evaluated with a visual analogue scale and food intake was assessed by using food records. The volunteers who drank the Hibiscus sabdariffa tea had lower perception of hunger (p=0.002) and greater feeling of satiety (p=0.010) and fullness (p=0.009) compared to control. Men who ingested the Hibiscus sabdariffa tea had an increase in nitrogen energy expenditure (water: 1501±290.7kcal, Hibiscus sabdariffa tea: 1619±288.9kcal; p=0.029). In comparison to control, men presented less perception of hunger (p=0.003) and desire to eat (p=0.016), increased satiety (p=0.021) and fullness (p=0.010), and women oxidized more fat (p=0.034) when they drank Hibiscus sabdariffa tea. There was no difference between treatments regarding the energy and macronutrient intake from the first meal and throughout the day (p>0.050) for all participants. The Hibiscus sabdariffa tea only affected energy expenditure and satiety responses in men. Clinical trial registry: ReBEC Platform of the Brazilian Clinical Trials Registry - RBR-5HZ86T Novelty bullets • Hibiscus sabdariffa tea promoted an increase in energy expenditure and caused less perception of hunger/desire to eat in men. • Hibiscus sabdariffa tea intake increased postprandial fat oxidation in women.

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.

Induced Changes

Resting energy expenditure (EE) has recently been shown to be reduced in elderly human subjects even after adjustment for body size and composition. The present study extended this examination of EE in relation to age by comparing the thermic effect of a protein meal in young men (YM 20-26 yr, n = 9), old men (OM 70-89 yr, n = 9), and old women (OW 67-75 yr, n = 6). EE was measured before and from 1 to 6 h after presentation of 60 g protein and of a control noncaloric meal on separate occasions. Despite substantial differences in body size and composition, the protein-induced increment in EE was similar in all groups [maximum increase: YM 0.21 +/- 0.05, OM 0.17 +/- 0.12, and OW 0.17 +/- 0.04 (SE) kcal/min]. Although fasting plasma norepinephrine (NE) levels differed among all three groups (YM less than OM less than OW), NE concentrations were not affected by protein ingestion. Because protein administration acutely promotes synthesis of dopamine (DA) and serotonin (5-HT), which are both capable of stimulating EE, blockade of extraneuronal synthesis of DA and 5-HT with carbidopa, a competitive inhibitor of aromatic-L-amino acid decarboxylase, failed to suppress (and actually increased) postprandial EE. These data demonstrate that not all mechanisms responsible for EE decline with age and that protein-induced changes in EE are more a function of the oral load itself than of the size, age, or antecedent diet of the individual ingesting the protein.

Resting Energy

We compared three independent techniques for measurement of total energy expenditure (TEE) in human subjects: 1) weight-maintaining energy intake (dietTEE), 2) 24-h chamber calorimetry (chamberTEE), and 3) differential elimination rates 2H2O and H(2)18O (isotopeTEE). Twenty-three healthy adult in-patients [19 never obese (NO), 2 obese (OB), and 2 formerly-obese (RO); 9 female, 14 malel] ingested a liquid formula diet (40% of calories as fat, 45% carbohydrate, 15% protein), the volume of which was adjusted until body weight was stable for at least 14 days. Body composition was then determined by hydrodensitometry, isotope dilution, and dual photon beam absorptiometry (DXA). The thermic effect of feeding (TEF) and resting energy expenditure [REE; measured before arising (dietREE) and after arising (chamberREE)] were determined by indirect calorimetry. Non-resting energy expenditure (NREE) was calculated as NREE = TEE - (REE + TEF). Subjects then gained or lost 10% of their body weight and were restudied as described above. All measures of TEE were significantly correlated (dietTEE vs. chamberTEE r2 = 0.75; dietTEE vs. isotopeTEE r2 = 0.88; isotopeTEE vs. chamberTEE r2 = 0.73; P < 0.0001). ChamberTEE (mean +/- SE = 2,107 +/- 64 kcal/day) was approximately 20% lower than either dietTEE (2,536 +/- 94 kcal/day, P < 0.0001) or isotopeTEE (2,564 +/- 83 kcal/day, P < 0.0001). When data were normalized to metabolic mass, weight gain of 10% was associated with significant increases in dietTEE (P < 0.005) and isotopeTEE (P < 0.05) but not chamberTEE; weight loss of 10% was associated with significant reductions in dietTEE (P < 0.005) and isotopeTEE (P < 0.05) but not chamberTEE. We conclude that measures of energy expenditure obtained in a highly controlled environment by caloric titration (dietTEE) or differential excretion rates of 2H2O and H(2)18O (isotopeTEE) are not significantly different and that measurements of TEE obtained in a respiratory chamber (chamberTEE) are significantly lower than dietTEE or isotopeTEE, probably largely due to limitations on physical activity in the chamber.

This study tests the hypotheses that (a) a mixture of whey protein, amino acids (AA), and carbohydrates (CHO) stimulates net muscle protein synthesis to a greater extent than isoenergetic CHO alone after resistance exercise; and (b) that the stimulatory effect of a protein, AA, and CHO mixture will last beyond the 1 st hour after intake. Eight subjects participated in 2 trials. In one (PAAC), they ingested 77.4 g CHO, 17.5 g whey protein, and 4.9 g AA 1 hr after resistance exercise. In the other (CON), 100 g CHO was ingested instead. They received a primed constant infusion of L-[2H5]-phenylalanine, and samples from femoral artery and vein, and biopsies from vastus lateralis were obtained. The area under the curve for net uptake of phenylalanine into muscle above pre-drink value was 128 ±42 mg • leg-1 (PAAC) versus 32 ± 10 mg - leg-1 (CON) for the 3 hr after the drink (p = .04). The net protein balance response to the mixture consisted of two components, one rapid immediate response, and a smaller delayed response about 90 min after drink, whereas in CON only a small delayed response was seen. We conclude that after resistance exercise, a mixture of whey protein, AA, and CHO stimulated muscle protein synthesis to a greater extent than isoenergetic CHO alone. Further, compared to previously reported findings, the addition of protein to an AA + CHO mixture seems to extend the anabolic effect.
