1. The energy balance of eleven male and fourteen female adult farmers was measured for 6 d after the harvest, in December-January. Their energy intake was recorded by weighing their food consumption and their energy expenditure was determined using indirect calorimetry.2. Body-weight, expressed as percentage of expected weight-for-height was 91 and 86% of the Inter-departmental Committee on Nutrition for National Development (1963) standard for women and men respectively.3. The staple foods were sorghum (Sorghum vulgare) and millet (Pennisetum typhoïdes); carbohydrates, fat and protein supplied approximately 80, 13 and 12% of the total energy of the diet respectively.4. In the male group, the mean energy intake (9.0 MJ (2148 kcal)) was in good agreement with the average energy output (8.91 MJ (2130 kcal)). By contrast, in the female group, the mean energy expenditure (8.11 MJ (1941 kcal)) exceeded the mean energy intake (6.3 MJ (1515 kcal)) and the deficit was statistically significant.5. This study allows an evaluation of the adequacy of food intake for subjects living in a particular hostile environment, by using their actual energy output instead of current standard values. The energy deficit found for female farmers whose energy intake was similar to that reported in other developing countries emphasizes the need for a better understanding of the regulation of energy balance in such conditions.

Main Determinants

Undernutrition is commonly associated with chronic disease in children and the elderly. Overnutrition is also, but less commonly, associated with chronic illness. In most diseases malnutrition arises because energy intake does not match energy output. Traditionally, the focus of research has been on abnormalities in energy expenditure, in the belief that these factors were the main determinants of energy imbalance. Recent studies using the doubly-labelled-water method to measure total energy expenditure, combined with more complex study design, have suggested an alternative conclusion. In many chronic diseases patient behaviour, and particularly energy intake, is responsible for energy imbalance and malnutrition. Energy balance studies have therefore provided a useful foundation for the design of strategies aimed at preventing or managing chronic malnutrition. However, modifying patient behaviour is an ambitious undertaking which may not be within the scope of existing clinical nutrition services. A number of non-traditional models of managing chronic malnutrition in children and the elderly are promising. Increasing recognition of the value of systematic review will also provide improved strategies for prevention and management of chronic malnutrition.

Brown Adipose Tissue Thermogenesis

This study was carried out to investigate the nutritional energetics of ovariectomized rats with or without ovarian hormone replacement. Rats were divided into five groups: 1) sham operated, 2) ovariectomized, 3) ovariectomized and treated with progesterone, 4) ovariectomized and treated with estradiol, or 5) ovariectomized and treated with estradiol and progesterone. After 36 days of treatment, energy contents of all five groups were determined together with energy content of food and feces. Brown adipose tissue thermogenesis was assessed through mitochondrial GDP binding assay. Results show that ovariectomy leads to a 16% increase in metabolizable energy intake. This increase was accompanied by a twofold increase in body energy gain. Progesterone did not further affect energy intake and gain in ovariectomized rats. However, increases in both food intake and energy gain were prevented by the estradiol replacement therapy. There was no difference in energy expenditure between sham-operated and ovariectomized rats in the absence of estradiol. In estradiol-treated animals, energy expenditure (kJ.kg body wt-0.75 . day-1) showed a slight increase. There was no difference in protein content of interscapular brown adipose tissue between all five groups. GDP binding was slightly reduced in ovariectomized estradiol-treated rats. It is concluded from this study that ovarian hormones produce their effects on energy balance mainly by altering food intake.

1.Fifteen female farmers (aged 18–47 years) from two villages of the Mossi Plateau in Upper-Volta participated in a survey in which their daily activity pattern and their energy expenditure were assessed. Eight of the subjects were investigated twice, in March (dry season) when there is no agricultural activity, and in July–August (rainy season) when heavy physical work is performed: mostly hoeing, weeding and replanting sorghum (Sorghum vulgare) and millet (Pennisetum typhoïdes).2. The mean height was 1.57 m and the mean weight 50.6 kg. The average percentage of body fat, calculated from skinfold thickness, was comparable to that of European females but the triceps skinfold was more than 60% below the standard value (Jelliffe, 1969). The type of activities and the period of time spent on each activity changed significantly with the season. The mean energy output rose from 9.7 MJ (2320 kcal) in March to 12.1 MJ (2890 kcal) in July–August for a 55 kg standard weight.3. In this paper, the extent of both the dally activity pattern of women living in a subsistence agriculture and their energy output is estimated. The results suggest that during the rainy season, the energy requirements of female farmers are much higher than usually estimated.

IntroductionThe Special Forces (SF) are an elite military group usually engaged in physically demanding field operations, resulting among others in high daily energy requirements. Optimising energy supply and nutritional requirements is therefore mandatory for success. The aim of this study was to estimate energy availability and nutrition during a Qualification Course (Q-Course) for Belgian SF.Methods21 participants recorded all foods and beverages consumed during four days in a structured food diary. Energy expenditure was measured with an accelerometer and fat mass measured with quadripolar impedance. Energy availability was calculated by the following formula: (energy intake by foods and beverages − energy expenditure for physical activity)/kg FFM/day (FFM, fat-free mass).ResultsThe mean (SD) total energy expenditure was 4926 kcal/day (238), with a minimum of 4645 kcal/day and a maximum of 5472 kcal/day. The mean (SD) total energy consumption was 4186 kcal/day (842), giving an energy balance ranging from −2005 kcal/day to 1113 kcal/day. The mean (SD) energy availability was 17 kcal/kg FFM/day, with a minimum of 1 kcal/kg FFM/day and a maximum of 44 kcal/kg FFM/day. The mean (SD) intake of carbohydrates was 6.8 g/kg body weight/day (1.5).ConclusionsDuring this studied Q-Course, energy intake was not optimal as demonstrated by an overall negative energy balance and low energy availability. High interindividual variations in energy intake were found, highlighting the importance of providing SF members nutritional education.

OBJECTIVE: To investigate the effect of nutritional recovery with rice bran on energy balance, leptin and insulin levels. METHODS: Weaned Wistar rats were fed on a 17% (Control - C) or 0.5% (Aproteic - A) protein diet for 12d. After this, rats were kept on a C diet (C) or recovered with control (Recovered Control - RC) or control plus recovered rice bran diet (Recovered Rice Bran - RRB). RESULTS: Despite the increased food intake, group A exhibited lower carcass fat associated to low serum leptin. RRB and RC groups showed lower carcass weight and energy intake and expenditure. Energy expenditure was positively associated with food intake and carcass weight. Negative correlations between HOMA-IR and energy expenditure and energy intake were observed. CONCLUSION: Nutritional recovery with rice bran did not modify energy balance, leptin and insulin levels.

AbstractSpecific nutritional requirements should be cover during childhood to ensure proper growth. The daily energy need is defined as the number of calories necessary to satisfy the total energy expenditure in a healthy and active organism. Since children are more inclined to be physically active during summer, their energy expenditure may vary during school days respect to summer days and a proper energy intake should be planned during both periods.The primary aim of this study was to evaluate the energy balance during school days and summer camp days in primary school children living in the city of Parma (Italy), attending the Giocampus programme.Participants were asked to complete a 3-day weighed food diary and to wear an activity tracker for the same 3 consecutive days twice: within a school week and a summer camp week. Height and body weight were measured at the beginning of each assessment week and BMI was calculated to define the weight status through the IOTF gender- and age-related cut-offs for children BMI. The mean energy balance was estimated as the difference between the mean total energy expenditure (calculated multiplying the daily physical activity level by the basal metabolic rate from the Schofield's predictive equation) and the mean daily energy intakes (obtained through the Italian food database of the European Institute of Oncology).Fifty-five children (49% F, 51% M, 8–10 y) correctly completed the study. In both periods, the mean BMI corresponded to normal weight status, without significant differences between genders. Energy intake did not change significantly between the assessment periods or between sexes. As expected, the minutes of inactivity decreased during the summer camp period. Moreover, males were more active than females, but the increase in the total energy expenditure from school to summer camp, related to the increased physical activity, was significant in both sexes. Energy balance was negative in both assessment periods and it changed significantly from school to summer camp days, decreasing in both sexes but being more negative for boys than for girls.Our results underline the importance of providing children with meals nutritionally adequate and suggest that the energy content of children's meals should be increased during particular conditions, like a summer camp, and continuously monitored to assure an adequate energy intake to cover the energy requirements during both school and summer camp days.

Resting Energy

Both in man and in animal models, changes in food intake and body composition in later life have been reported after alterations in perinatal nutrition. Therefore, we hypothesised that early postnatal undernutrition in the rat induces permanent changes in energy balance. Food restriction (FR) during lactation was achieved by enlarging litter size to twenty pups, whereas control animals were raised in litters containing ten pups. Energy intake and resting energy expenditure were determined in adult males. Early postnatal FR resulted in acute growth restriction followed by incomplete catch-up in body weight, body length and BMI. At the age of 12 months, middle-aged FR males had significantly lower absolute resting energy expenditure (200 v. 216 kJ/24 h, P = 0·009), absolute energy intake (281 v. 310 kJ/24 h, P = 0·001) and energy intake adjusted for BMI (284 v. 305 kJ/24 h, P = 0·016) than controls, whereas resting energy expenditure adjusted for BMI did not differ significantly between the groups (204 v. 211 kJ/24 h, P = 0·156). The amount of energy remaining for other functions was lower in FR males (80 v. 94 kJ/24 h, P = 0·044). Comparable data were obtained at the age of 6 months. These results indicate that in rats energy balance can be programmed by early nutrition. A low early postnatal food intake appears to programme these animals for a low energy intake and to remain slender in adult life.

1. The energy balance and activity allocation of eight male and eight female Indian farmers were meaured for 4 d during 10 months in both the dry and wet seasons of 1983.2. All food prepared and eaten was weighed and nutrient values were calculated from food composition tables.3. Average energy costs per unit mass for fifteen tasks were estimated from data obtained using a Kofranyi-Michaelis respirometer. Each subject was observed from 05.00 to 20.00 hours and activities were recorded for each minute. The remaining activity was determined by recall.4. Activity allocation was categorized qualitatively into time spent on economically productive work, free time and body maintenance.5. The mean weight for male subjects was 48.2 kg; the average female weight was only 36.9 kg. The mean height for male and female subjects was 1.61 m and 1.49 m respectively.6. For male subjects, the daily mean energy intake of 9.81 MJ (2350 kcal) was close to the calculated energy output of 9.54 MJ (2285 kcal).7. The women's calculated daily expenditure of 8.22 MJ (1968 kcal) was slightly higher than their mean energy intake of 7.73 MJ (1852 kcal).8. Although intake and output varied in relation to sex, weight and wealth the mean intake per kg body mass was equal for both males and females at 210 kJ (50 kcal) per kg. This is close to the minimum requirement for active Third World farmers.9. The women spent significantly more time on economically productive work activities than the men (11.1 v. 8.1 h/d). Although female energy intake was 27 % less than males, their productive work time was 27% higher.

AbstractObjectiveTo validate energy intake (EI) estimated from pre-coded food diaries against energy expenditure (EE) measured with a validated position-and-movement monitor (ActiReg®) in groups of 13-year-old Norwegian schoolchildren.DesignTwo studies were conducted. In study 1 the monitoring period was 4 days; participants recorded their food intake for four consecutive weekdays using food diaries and wore the ActiReg® during the same period. In study 2 the monitoring period was 7 days; participants recorded their food intake for four consecutive days but wore the ActiReg® for a whole week.SettingsParticipants were recruited from grade 8 in a school in and one outside Oslo (Norway).SubjectsForty-one and 31 participants from study 1 and 2, respectively, completed the study.ResultsThe group average EI was 34% lower than the measured EE in study 1 and 24% lower in study 2. The width of the 95% confidence limits of agreement in a Bland–Altman plot for EI and EE varied from -0.2 MJ to 8.2 MJ in study 1 and from -2.3 MJ to 6.9 MJ in study 2. The Pearson correlation coefficients between reported energy intake and expenditure were 0.47 (P = 0.002) in study 1 and 0.74 (P < 0.001) in study 2.ConclusionThe data showed that there was substantial variability in the accuracy of the food diary at the individual level. Furthermore, the diary underestimated the average energy intake. The ability of the food diary to rank individuals according to energy intake was found to be good in one of the studies and moderate in the other.

SUMMARYWe have previously observed that female MF1 mice appeared to reach a limit in their food intake and milk production during late lactation, reaching a plateau between days 13 and 16 of lactation and between litter sizes of 9 and 15. These mice did not increase their food intake when forced to raise more offspring or when manipulated to be concurrently pregnant during late lactation, yet they did eat significantly more food at the peak of their second sequential lactation or when challenged with food of reduced energy content. These data suggest that apparent limits on sustained energy intake in this strain may not reflect central limitations but rather peripheral constraints at the mammary glands. In this study, we aimed to determine whether these were indeed limits by increasing the demands on the females during late lactation by cold-exposure (8°C). Females responded to this manipulation by significantly increasing their food intake (F1,73=77.53, P&lt;0.001) above that of lactating females kept in warmer conditions (21°C). In addition, there was a significant reduction in the number of pups raised in the cold (t=2.36, d.f.=18, P=0.03), with the majority of the mortality occurring within the first 2 days of cold-exposure. The mean mass of the pups raised in the cold was significantly lower (F1,74=13.8, P&lt;0.001) than that of those raised in the warm. Despite the cold-exposure and the increased food intake, there was no difference in the resting metabolic rates of the two groups of mothers or in the lengths of their small intestine. The greater food intake of lactating mice during cold-exposure supported our previous observations that they were capable of eating more food than the previously suggested limit of 23.1gday−1. However, the milk energy output of females in the cold was also significantly higher than in the warm (F1,15=11.99, P=0.003), indicating that the asymptotic food intake of females in the warm was not mediated by limitations in their milk production. Sustained energy intake in these mice does not appear to be centrally or peripherally limited. Rather, the mice may restrain their use of energy during their first lactation because of life-history consequences for future reproductive attempts.
