Ad Libitum

Dietary regulation of appetite may contribute to the prevention and management of excess body weight. The present study examined the effect of consumption of individual dairy products as snacks on appetite and subsequent ad libitum lunch energy intake. In a randomised cross-over trial, forty overweight men (age 32 (sd 9) years; BMI 27 (sd 2) kg/m2) attended four sessions 1 week apart and received three isoenergetic (841 kJ) and isovolumetric (410 ml) servings of dairy snacks or water (control) 120 min after breakfast. Appetite profile was determined throughout the morning and ad libitum energy intake was assessed 90 min after the intake of snacks. Concentrations of amino acids, glucose, insulin, ghrelin and peptide tyrosine tyrosine were measured at baseline (0 min) and 80 min after the intake of snacks. Although the results showed that yogurt had the greatest suppressive effect on appetite, this could be confounded by the poor sensory ratings of yogurt. Hunger rating was 8, 10 and 24 % (P < 0·001) lower after the intake of yogurt than cheese, milk and water, respectively. Energy intake was 11, 9 and 12 % (P < 0·02) lower after the intake of yogurt, cheese and milk, respectively, compared with water (4312 (se 226) kJ). Although there was no difference in the postprandial responses of hormones, alanine and isoleucine concentrations were higher after the intake of yogurt than cheese and milk (P < 0·05). In conclusion, all dairy snacks reduced appetite and lunch intake compared with water. Yogurt had the greatest effect on suppressing subjective appetite ratings, but did not affect subsequent food intake compared with milk or cheese.

Ad Libitum

Sugar-sweetened beverage (sugar-SB) consumption is associated with body weight gain. We investigated whether the changes of (Δ) circulating leptin contribute to weight gain and ad libitum food intake in young adults consuming sugar-SB for two weeks. In a parallel, double-blinded, intervention study, participants (n = 131; BMI 18–35 kg/m2; 18–40 years) consumed three beverages/day containing aspartame or 25% energy requirement as glucose, fructose, high fructose corn syrup (HFCS) or sucrose (n = 23–28/group). Body weight, ad libitum food intake and 24-h leptin area under the curve (AUC) were assessed at Week 0 and at the end of Week 2. The Δbody weight was not different among groups (p = 0.092), but the increases in subjects consuming HFCS- (p = 0.0008) and glucose-SB (p = 0.018) were significant compared with Week 0. Subjects consuming sucrose- (+14%, p < 0.0015), fructose- (+9%, p = 0.015) and HFCS-SB (+8%, p = 0.017) increased energy intake during the ad libitum food intake trial compared with subjects consuming aspartame-SB (−4%, p = 0.0037, effect of SB). Fructose-SB decreased (−14 ng/mL × 24 h, p = 0.0006) and sucrose-SB increased (+25 ng/mL × 24 h, p = 0.025 vs. Week 0; p = 0.0008 vs. fructose-SB) 24-h leptin AUC. The Δad libitum food intake and Δbody weight were not influenced by circulating leptin in young adults consuming sugar-SB for 2 weeks. Studies are needed to determine the mechanisms mediating increased energy intake in subjects consuming sugar-SB.

The Impact

Research demonstrates that exercise acutely reduces appetite by stimulating the secretion of gut-derived satiety hormones. Currently there is a paucity of research examining the impact of postexercise nutrient intake on appetite regulation. The objective of this study was to examine how postexercise fasting versus feeding impacts the postexercise appetite response. In a randomized crossover intervention, 14 participants (body mass index: 26.9 ± 3.5 kg·m−2; age: 26.8 ± 6.7 years) received 1 of 2 recovery beverages: (i) water control (FAST) or (ii) sweetened-milk (FED) after completing a 45-min (65%–70% peak oxygen uptake) evening exercise session (∼1900 h). Energy intake was assessed through a fasted ad libitum breakfast meal and 3-day food diaries. Perceived appetite was assessed using visual analogue scales. Appetite-regulating hormones glucagon-like peptide-1 (GLP-1), peptide tyrosine-tyrosine (PYY), and acyl-ghrelin were assessed pre-exercise, 1 h after exercise, and the morning following exercise. FAST increased subjective hunger compared with FED (P < 0.05). PYY and GLP-1 after exercise were decreased and acyl-ghrelin was increased in FAST, with these differences disappearing the day after exercise (P < 0.05). Ad libitum energy intake at breakfast the following morning did not differ between trials. Overall, in the absence of postexercise macronutrient consumption, there was a pronounced increase in objective and subjective appetite after exercise. The orexigenic effects of postexercise fasting, however, were not observed the morning following exercise. Novelty Postexercise fasting leads to reduced GLP-1 and PYY and increased hunger. Reduced GLP-1 and PYY after exercise is blunted by postexercise nutrient intake. Energy intake the day after exercise is not influenced by postexercise fasting.

High Energy Intake

Background: Population exposed to chronic undernutrition in early life seems to be more susceptible to obesity in adulthood due to the development of mechanisms that improve the efficiency of energy use. Therefore, these individuals have relatively reduced energy requirements (thrifty phenotype). Objective: To investigate, among women living on severe socioeconomic vulnerability, whether short stature, a marker for undernutrition in early life, is associated with excess body weight but not with a high energy intake. Methods: This cross-sectional study, carried out between July and November 2008, evaluated 1308 women from all (N = 39) Quilombola communities of Alagoas. Adequacy of energy intake was estimated by the ratio between energetic ingestion and the estimated energy requirement (EER). Results: The prevalence of short stature (≤ 154.8 cm) was 43.0% and 52.4% had excess body weight (body mass index ≥ 25 kg/m2), being that 33.1% were overweight and 19.3% obese. Excess body weight was higher among women with short stature (56.6% vs 49.2%; P = .008), even after adjusting for age, energy intake, and per capita income (prevalence ratio = 1.16; 95% confidence interval = 1.04; 1.28). The ratio of energy intake/EER was independent of women’s stature. Conclusion: Excess body weight among Quilombola women represents a serious health problem. Short stature was significantly associated with excess body weight but not with a high energy intake. “Thrifty phenotype” may be one of the plausible explanations for this finding.

The present study compared the effects of a high- and normal-casein-protein breakfast on satiety, ‘satiety’ hormones, plasma amino acid responses and subsequent energy intake. Twenty-five healthy subjects (BMI 23·9 (sem 0·3) kg/m2; age 22 (sem 1) years) received a subject-specific standardised breakfast (20 % of daily energy requirements): a custard with casein as the single protein source with either 10, 55 and 35 (normal-casein breakfast) or 25, 55 and 20 (high-casein breakfast) % of energy (En%) from protein, carbohydrate and fat respectively in a randomised, single-blind design. Appetite profile (visual analogue scale; VAS), plasma glucose, insulin, glucagon-like peptide 1, ghrelin and amino acid concentrations were determined for 4 h; here the sensitive moment in time for lunch was determined. Subjects came for a second set of experiments and received the same custards for breakfast, and an ad libitum lunch was offered at 180 min after breakfast; energy intake was assessed. There were increased scores of fullness and satiety after the 25 En% casein-custard compared with the 10 En% casein-custard, particularly at 180 min (26 (sem 4) v. 11 (sem 5) mm VAS; P < 0·01) and 240 min (13 (sem 5) v. − 1 (sem 5) mm VAS; P < 0·01). This coincided with prolonged elevated plasma amino acid concentrations; total amino acids and branched-chain amino acids were higher after the 25 En% casein-custard compared with the 10 En% casein-custard at 180 and 240 min (P < 0·001). There was no difference in energy intake (3080 (sem 229) v. 3133 (sem 226) kJ for 25 En% and 10 En% respectively; NS) from the ad libitum lunch. In conclusion, a breakfast with 25 % of energy from casein is rated as being more satiating than a breakfast with 10 % of energy from casein at 3 and 4 h after breakfast, coinciding with prolonged elevated concentrations of plasma amino acids, but does not reduce subsequent energy intake.

Forty crossbred lambs (20 rams, 20 ewes) were penned in two groups (equal numbers of each sex) and fed a pelleted ration either ad libitum (H) or 70% of expected ad libitum intake (70% H). Ten lambs (5 rams, 5 ewes) from both groups (H and 70% H) were slaughtered after 40 days on feed while the remaining lambs were slaughtered after 61 days on feed. All lambs were measured for carcass leanness using an EMME machine immediately prior to slaughter. The offal components were weighed fresh and the alimentary tract was emptied of digesta. One side of each carcass was broken into four cuts (leg, loin, rib, shoulder) which were further separated into fat, muscle and bone. EMME numbers only marginally increased the amount of explained variation in the prediction of lean weight over that provided by liveweight alone. Growth coefficients between sexes and intake groups (H, 70% H) for the offal components relative to empty body weight were homogeneous, indicating that sex and dietary energy intake did not affect the relative growth of the offal components. Ram lambs had heavier heads and smaller intestines than ewe lambs, but contained less caul and mesenteric fat than ewe lambs at the same empty body weight. Lambs fed H had a greater weight of pelt, liver and caul fat, but had a lower warm carcass weight and less mesenteric fat than lambs fed 70% H at the same empty body weight. Growth coefficients between sexes and intake groups for the carcass tissues relative to physically separated tissue weights (muscle, bone, fat) were homogeneous, which indicated that sex and intake did not affect the relative growth of the carcass tissues. Ram lamb carcasses had a greater weight of muscle in the shoulder and less muscle in the leg than ewe lamb carcasses at the same carcass muscle weight. Dietary energy intake had small but statistically significant effects on carcass muscle distribution. Lambs fed 70% H produced carcasses with proportionally more muscle in the leg and less muscle in the loin and shoulder than lambs fed H at the same carcass muscle weight. Sex and dietary energy intake had minor effects on carcass bone and fat distribution. Key words: Lambs, carcass, offal, fat, EMME

AbstractThe effect of energy supply on physical composition of body weight gain between 45 and 100 kg was studied in Large White castrated males (cLW), crossbred Pietrain × Large White castrated males (cPPX) and boars (bPPX). The pigs were either given food ad libitum and kept in individual pens in experiment 1, or allocated to four energy levels (0·70, 0·80, 0·90, and 1·00 ad libitum) and kept in metabolism cages in experiment 2. Daily protein supplies were calculated to be the same at the four energy levels within each type of pig and non-limiting for growth. Five additional animals for each type of pig were slaughtered at 45 kg. Daily tissue gain was measured according to the comparative slaughter technique. The daily lean gain increased with metabolizable energy (ME) intake according to a linear-plateau relationship whereas the daily fat gain increased linearly. The type of pig significantly affected the slope of the relationship between lean gain and ME intake (from 15 to 22 g per extra MJ ME) but not the slope of the relationship between fat gain and ME intake (10 g per extra MJ ME on average). Increased energy intake was associated with increased fatness of body-weight gain, which was higher in cLW and cPP× than in bPP×.

The Relationship

Energy, carbon, and nitrogen balances were determined in adult wether sheep given a diet of lucerne hay and whole oats at several planes of nutrition between fasting and ad libitum. Four sheep were studied when their weight was c. 30 kg (10% fat) and later when they weighed c. 75 kg (33% fat); another four were studied at c. 70 kg (30% fat) and later at c. 45 kg (16% fat). The most obvious effect of fatness was loss of appetite. Voluntary food intake began to decline when body weight approached 60 kg and was half of the maximal amount when the sheep weighed 70 kg or more; one very fat sheep ate only 100–200 g food/day for several weeks. 1n addition, environmental changes such as transfer from a pen to a cage or respiration chamber often caused temporary inappetence when the sheep were in fat condition but seldom when they were lean. Fasting metabolic rate increased with body weight in accordance with the relationship generally applicable to adult sheep except when the sheep were in the anorectic phase of obesity, at which time their metabolic rate was 30–40% above normal. The digestibility of the diet was not dependent on the fatness of the sheep, nor was the relationship between metabolizable and digestible energy. At each level of feeding, the heaviest sheep produced most heat, but differences were less than at fasting; oxidation of fat, rather than protein, was responsible. When daily heat production and metabolizable energy were both expressed as multiples of the fasting energy loss, all sheep conformed to one relationship; the same held for the relation between energy balance and metabolizable energy. Net efficiency (change of energy balance divided by change of metabolizable energy intake) was 78% for maintenance and 55% for production, irrespective of body condition. Gross efficiency (energy storage divided by gross energy intake) was strongly influenced by body condition. When fed ad libitum, thin sheep achieved an efficiency of c. 26 % and fat sheep reached 21 % whereas anorectic very fat sheep never exceeded 10%. Thin, fat, and very fat sheep required 400, 500 and 650 g dry matter/day respectively for maintenance (zero gross efficiency).

AbstractObjectiveTo examine whether eating while watching television poses a risk for poor nutrition and excess body weight over and above that of time spent watching television.DesignWe analysed data of grade 5 students participating in a comprehensive population-based survey in the Canadian province of Nova Scotia. This survey included the Harvard’s Youth Food Frequency Questionnaire, students’ height and weight measurements, and a parent survey. We applied multivariable linear and logistic random effects models to quantify the associations of watching television and eating while watching television with diet quality and body weight.SettingThe province of Nova Scotia, Canada.SubjectsGrade 5 students (n4966).ResultsEating supper while watching television negatively affected the consumption of fruits and vegetables and overall diet quality. More frequent supper while watching television was associated with more soft drink consumption, a higher percentage energy intake from sugar out of total energy from carbohydrate, a higher percentage energy intake from fat, and a higher percentage energy intake from snack food. These associations appeared independent of time children spent watching television. Both watching television and eating while watching television were positively and independently associated with overweight.ConclusionsOur observations suggest that both sedentary behaviours from time spent watching television as well as poor nutrition as a result of eating while watching television contribute to overweight in children. They justify current health promotion targeting time spent watching television and call for promotion of family meals as a means to avoid eating in front of the television.

The utilization of good-quality and poor-quality roughages (lucerne hay and oat straw) by red and grey kangaroos, Megaleia rufa and Macropus giganteus, compared with sheep was investigated by means of digestibility trials in individual metabolism cages. On average the kangaroos ate slightly less per unit metabolic body weight than the sheep when fed ad libitum, but the differences were not significant. They digested a similar percentage of lucerne dry matter but digested straw much less well, mainly because of their poor ability to digest crude fibre. When nitrogen intakes were low, with the straw diet, the kangaroos retained nitrogen less well than sheep although the digestibility of the crude protein was similar for kangaroos and sheep. The kangaroos appeared to have relatively low energy and nitrogen requirements, probably because of their low metabolic rate, and their weight losses were similar to sheep on the poor-quality diet despite much lower digestible dry matter intakes per unit metabolic body weight. There were no differences between red and grey kangaroos in dry matter digestibilities, nitrogen metabolism, or rate of passage.
