Objective: This study was conducted to determine the energy intake of adult residents of district 13 of Tehran and compare the results with their energy requirements. Design: In this cross-sectional study, 403 subjects were selected by random sampling, including 145 men and 151 women aged 25–50 years and 57 men and 50 women over 50 years old in the framework of Tehran Lipid and Glucose Study (TLGS). Measurements: Height, body weight, waist and hip circumferences were measured, and the body mass index (BMI) and waist-to-hip ratio (WHR) were calculated. Mean energy requirements for each sex-age group were estimated by multiplying specific coefficients (allocated to each group) by body weight and resting energy expenditure (REE), and the results of both methods were compared with mean energy values recommended by Food and Agriculture Organization (FAO) /World Health Organization (WHO) and the U.S. recommended dietary allowance (RDA). Dietary assessment was performed by 48-hour diet recall. A ratio of energy intake to basal metabolic rate lower than 1.27 was considered as under-reporting. Physical activity was evaluated by standard questionnaire of the Lipid Research Clinics (LRC). Results: Women were significantly more overweight and obese than men (p < 0.001) and older women were more obese than younger ones (p < 0.05). Only one-third of the study population had adequate physical activity. Women had significantly lower physical activity than men (p < 0.01). Energy requirements for both age and sex groups were lower than recommended daily allowances for energy: men 25–50; 2576 vs. 2900; men > 50: 2155 vs. 2300; women 20–50: 2045 vs. 2200 and women > 50: 1817 vs. 1900 kilocalories (kcal). Reported energy intake of men was higher and that of women was lower than the RDA. Forty percent of women and 14% of men under-reported their energy intake. Conclusion: The energy requirement of the average Tehranian is lower than daily allowances; conditions of obesity and overweight are more prevalent in women. There is high frequency of under-reporting of energy intake in women. Lifestyle modifications to improve dietary habits and to increase physical activity are recommended to decrease overweight and obesity in urban population of Tehran.

ABSTRACTBackgroundThe COVID-19 pandemic has caused people to shelter-at-home for an extended period, resulting in a sudden rise in unstructured time. This unexpected disruption in everyday life has raised concerns about weight management, especially in high-risk populations of women and individuals with overweight and obesity. This study aimed to investigate the changes in behaviors that may impact energy intake and/or energy expenditure in U.S. adults during the home confinement.MethodsCross-sectional data from 1,779 adults were collected using an online Qualtrics survey between April 24th and May 4th, 2020. Self-reported data on demographics, eating behaviors, physical activity, sleep, screen time, takeout food intake, and food purchasing behaviors were collected. Chi-Square analyses were conducted to evaluate differences in the percent of participants reporting increasing, decreasing, or staying the same in each health behavior since the COVID-19 outbreak in their area. Each analysis was followed by comparing whether increases or decreases were more likely for each health behavior. Similar comparisons were made between male and female participants and between body mass index (BMI) categories.ResultsWe observed an increase in the intake of both healthy and energy-dense unhealthy foods and snacks during the home confinement. Participants also reported increases in sedentary activities and decrease in physical activity, alcohol intake, and consumption of takeout meals during this time. In women, several behavioral changes support greater energy intake and less energy expenditure than men. No clear difference in patterns was observed across BMI status.ConclusionAcute changes in behaviors underscore the significance of a sudden increase in unstructured time at home on potential weight gain. Our findings support the need to implement and support measures that promote strategies to maintain body weight and establish a methodology to collect body weight data at multiple time points to longitudinally assess the dynamic relationship between behaviors and body weight change.

AbstractObjectiveTo test equations for calculating infants’ energy requirements as a simple and reliable instrument for estimating the amount of breast milk consumed in epidemiological studies where test-weighing is not possible.DesignInfants’ energy requirements were calculated using three different equations based on reference data and compared with actual energy intakes assessed using the 3 d weighed dietary records of breast-fed infants from the DOrtmund Nutritional and Anthropometric Longitudinally Designed (DONALD) Study.SettingA sub-sample of 323 infants from the German DONALD Study who were predominantly breast-fed for at least the first four months of life, and who had 3 d weighed dietary records and repeated body weight measurements within the first year of life.SubjectsHealthy, term infants breast-fed for at least 4 months, 0–12 months of age.ResultsThe overall differences between measured energy intake and calculated energy requirements were quite small, never more than 10 % of total energy intake, and smaller than the mean variance of energy intake between the three days of recording. The equation of best fit incorporated body weight and recent growth, while the worst fit was found for the equation not considering body weight.ConclusionsBreast milk consumption in fully and partially breast-fed infants can be reasonably quantified by calculating the infants’ individual energy requirements via simple equations. This provides a feasible approach for estimating infant energy intake in epidemiological studies where test-weighing of breast milk is not possible.

Fat Free Mass

In adults, body mass (BM) and its components fat-free mass (FFM) and fat mass (FM) are normally regulated at a constant level. Changes in FM and FFM are dependent on energy intake (EI) and energy expenditure (EE). The body defends itself against an imbalance between EI and EE by adjusting, within limits, the one to the other. When, at a given EI or EE, energy balance cannot be reached, FM and FFM will change, eventually resulting in an energy balance at a new value. A model is described which simulates changes in FM and FFM using EI and physical activity (PA) as input variables. EI can be set at a chosen value or calculated from dietary intake with a database on the net energy of foods. PA can be set at a chosen multiple of basal metabolic rate (BMR) or calculated from the activity budget with a database on the energy cost of activities in multiples of BMR. BMR is calculated from FFM and FM and, if necessary, FFM is calculated from BM, height, sex and age, using empirical equations. The model uses existing knowledge on the adaptation of energy expenditure (EE) to an imbalance between EI and EE, and to resulting changes in FM and FFM. Mobilization and storage of energy as FM and FFM are functions of the relative size of the deficit (EI/EE) and of the body composition. The model was validated with three recent studies measuring EE at a fixed EI during an interval with energy restriction, overfeeding and exercise training respectively. Discrepancies between observed and simulated changes in energy stores were within the measurement precision of EI, EE and body composition. Thus the consequences of a change in dietary intake or a change in physical activity on body weight and body composition can be simulated.

Obesity is one of the most widespread diseases of our days .Because of its wild distribution not only among adults but also among children, adolescents and young people, the WORLD HEALTH ORGANISATION (WHO) include it in the list of socially and medically significant diseases with serious effects on human health. The factors for its etiology and development are complex, but the most authors identify the unhealthy nutritional habits and lack of regular physical activity as leading ones. The purpose of this study was to reveal the most common causes of weight increase above its normal levels in medical students. Material and methods. The study included 120 students from the Medical Faculty of the Thracian university -Stara Zagora. They carried out an individual anonymous questionnaire, with a total of 21 questions – closed, open and mixed, which aim was to reveal some of the possible causes leading to excess weight in the contingent studied. Methods used: Research and analysis of information sources, survey sociological method, alternative analysis. Results and discussion. In that report we will analyse the answers to those questions concerning the nutritional habits and behaviour of the respondents. It turns out that among the most common reasons for increasing body weight above the normal range is the presence of a number of unhealthy nutritional habits, such as the intake of high-energy food products of low biological value, the intake of a higher amount of food/overeating/and irregular eating. Conclusion. Based on the research carried out, we can summarize that a large number of the students surveyed demonstrate a good knowledge about the healthy and balanced nutrition, but unfortunately most of them do not follow it because of their dynamic and strenuous daily life, and this in combination with the decreased habitual physical activity will inevitably lead to an increased body weight.

The present study used the recommendations of the World Health Organization to measure nutritional status, doing so through the body mass index. The purpose of the study is to relate the nutritional status of kindergarten and first grade students from two municipal schools in the Maule region with the eating habits and physical activity perceived by the parents. 87 kindergarten and first grade students were evaluated. The results show that in kindergarten overweight and obesity reached (76.2%) respectively, and in first grade an overweight and obesity of (70.6%), however, no greater relationship was found between knowledge of the parents of the importance of physical activity in the life of their children and their nutritional status as well as in the eating habits that they reported of their children in relation to nutritional status. Students are in a nutritional state of risk and the perception of parents is low in terms of the knowledge they have regarding the practice of physical activity and eating habits, being directly related to the poor nutritional status that they present.

The increase in prolificacy at weaning is less than that at farrowing due to increased loss of piglets. As a result, farmers focus more on solutions that can prevent difficult parturition or a decrease in milk production. The body condition of the sow influences both factors. A model developed to estimate energy requirements of gestating sows was used to monitor the body weight and back fat thickness (BT) at farrowing, through the creation of a demonstration farm that included 7 batches of 24 sows. Daily feed allowance was adapted to characteristics of each sow at the beginning of gestation. Based on data collected since 2005 from 5140 gestations in different housing systems, the BT averaged 19.3 mm at farrowing, with no significant differences among housing systems. Within-batch variability in BT ranged from 3–4 mm and is expected to improve in the future by using sensors to automatically weigh and measure physical activity towards a real-time assessment of energy requirements. The next step in reducing feed costs and environmental impacts is to consider amino-acid and phosphorus requirements in the precision-feeding strategy.

1. Twenty apparently healthy and normal Nigerian male students, resident at the University of Ibadan campus, were studied for seven consecutive days to assess their food energy intake and expenditure and pattern of their daily activities.2. The mean age (years) of the group was 24.0 (SD 3.23, range 20–30), mean height (m) 1.71 (SD 0.06, range 1.61–1.84) and body-weight (kg) was 61.1 (SD 5.01, range 51.0–69.5).3. The food intake of each subject was obtained by direct weighing and its energy value determined using a ballistic bomb calorimeter. Patterns of daily activities were recorded and the energy costs of representative activities were determined by indirect calorimetry.4. Activities mainly involved sitting, mean 580 (SD 167, range 394–732) min/d. Sleeping and standing activities took a mean of 445 (SD 112) and 115 (SD 75) min/d respectively. Personal domestic activities took a mean of 94 (SD 40) min/d.5. The mean energy intake of the group was 11 182 (SD 1970) kJ/d or 183 (SD 32) kJ/kg body-weight per d. This value is lower than the 12.5 MJ/d recommended by the Food and Agriculture Organization (FAO)/World Health Organization (WHO) (1973) as the energy requirement for an adult man engaged in moderate activities, but it is higher than the FAO/WHO/United Nations University (UNU) (1985) recommended value of 10.8 MJ/d for a male office clerk (light activity). It is also lower than the recommended energy requirement of 11.6 MJ/d for a subsistence farmer (moderately active work) (FAO/WHO/UNU, 1985).6. The mean energy expenditure of the male subjects was 9876 (SD 1064, range 7159–12259) kJ/d and was lower than mean intake.7. The energy intake and expenditure values indicated that the groups participating in the present study were not physically very active. It is an indication that the Nigerian male students expended less but probably consumed more energy than required. It is suggested for health reasons and for mental fitness that the Nigerian male students might undertake more physical exercise.

AbstractUsing data from the National Health and Nutrition Examination Survey (NHANES) 2003–2012, we investigated the prevalence and characteristics of under-reporting and over-reporting of energy intake (EI) among 19 693 US adults ≥20 years of age. For the assessment of EI, two 24-h dietary recalls were conducted using the US Department of Agriculture Automated Multiple-Pass Method. Under-reporters, acceptable reporters and over-reporters of EI were identified by two methods based on the 95 % confidence limits: (1) for agreement between the ratio of EI to BMR and a physical activity level for sedentary lifestyle (1·55) and (2) of the expected ratio of EI to estimated energy requirement (EER) of 1·0. BMR was calculated using Schofield’s equations. EER was calculated using equations from the US Dietary Reference Intakes, assuming ‘low active’ level of physical activity. The risk of being an under-reporter or over-reporter compared with an acceptable reporter was analysed using multiple logistic regression. Percentages of under-reporters, acceptable reporters and over-reporters were 25·1, 73·5 and 1·4 %, respectively, based on EI:BMR, and 25·7, 71·8 and 2·5 %, respectively, based on EI:EER. Under-reporting was associated with female sex, older age, non-Hispanic blacks (compared with non-Hispanic whites), lower education, lower family poverty income ratio and overweight and obesity. Over-reporting was associated with male sex, younger age, lower family poverty income ratio, current smoking (compared with never smoking) and underweight. Similar findings were obtained when analysing only the first 24-h recall data from NHANES 1999–2012 (n 28 794). In conclusion, we found that misreporting of EI, particularly under-reporting, remains prevalent and differential in US adults.

Diet And Physical Activity

Background: Adolescence is the age where the influence of marketing world is high and choice of right food and exercise becomes hurdled. The World Health Organization alarm on increasing NCDs among adolescents ratifies the need for appropriate intervention at this age group. The objective of the study was to find out the association between diet and physical activity with body mass index (BMI) among dental students in Puducherry.Methods: A cross-sectional study was conducted in October 2016 among 85 dental students of Sri Venkateshwaraa Dental College, Puducherry. A self administered semi structured questionnaire was used to collect information about diet and physical activity. Height and weight were measured for all participants to compute BMI.Results: The mean age of the study participants was 19.32 ± 0.6 yrs. Majority of them were females (76.5%). About 33% of students had normal BMI. Junk food consumption was 91.8% and 65% had habit of skipping meals. Only 38% of the students were doing regular physical activity. A significant association between calorie and protein intake with BMI categories viz: underweight, normal, overweight and obesity was observed (p<0.001). There was a significant association (OR=18.4, 95%CI-6.1, 54.6) between excess calorie intake and BMI but not between physical activity and BMI (OR=1.2, 95% CI-0.5, 3).Conclusions: Improper dietary habits including high calorie/protein intake was associated with increased BMI among the dental students. The role of regular physical activity alone as a single factor influencing variations in BMI among the students could not be established in the study.

Norfolk Terrier

An appropriate energy intake for healthy growth can reduce the risk of obesity and co-morbidities, such as orthopaedic diseases. The 2006 National Research Council (NRC) universal equation calculates the energy requirement of growing dogs based on predicted adult body weight, but evidence suggests a revision may be required. This study investigates the energy requirements of seventeen Norfolk terrier puppies over their first year (10 to 52 weeks). Puppies were individually fed complete and balanced diets in amounts to maintain an optimal body condition score (BCS), recording intake daily and body weight and BCS weekly. To monitor health a veterinary examination, haematology and plasma biochemistry and serum measures of bone turnover were undertaken every 12 weeks. Skeletal development was assessed using dual-energy X-ray absorptiometry (26 and 52 weeks). Puppies were clinically healthy with normal skeletal development and healthy growth throughout. The energy intake to achieve this was significantly lower than that predicted by the NRC (2006) equation at all time points, with largest mean difference of 285 kJ/kg0·75 per day at 10 weeks. If fed according to the NRC 2006 equation, dogs would have been in positive energy balance, possibly leading to obesity. These data support a revision to the NRC (2006) equation.
