Balanced energy intake -

EARs for an individual vary throughout the life course. During infancy and childhood, it is essential that energy is sufficient to meet requirements for growth, which is rapid during some stages of childhood. Energy requirements tend to increase up to the age of years.

On average, boys have slightly higher requirements than girls and this persists throughout adulthood, being linked to body size and muscle mass. After the age of 50 years, energy requirements are estimated to decrease further in women in particular and after age 60 years in men, which is partly due to a reduction in the basal metabolic rate BMR , as well as a reduced level of activity and an assumed reduction in body weight.

Find out more about the EARs for the UK population on our page on nutrient requirements. In order for people to maintain their bodyweight, their energy intake must equal their energy expenditure. Failure to maintain energy balance will result in weight change.

Energy balance can be maintained by regulating energy intake through the diet , energy expenditure adjusting physical activity level to match intake or a combination of both.

The average daily energy intake of UK adults aged years is kJ kcal for men and kJ kcal for women. These figures are below the EARs for both men and women and have been falling steadily, year on year, for some time. At the same time, the population has become ever more sedentary and population obesity levels are still on the increase.

Assuming the estimates of intake are correct, this means that energy expenditure levels have fallen to a greater extent than the reduction in dietary energy intake. This emphasizes the need for people to become more active because as energy intake falls, the greater the likelihood that micronutrient needs will no longer be met.

The easiest way to increase physical activity level is to incorporate more activity into daily routines, like walking or cycling instead of driving short distances and taking up more active hobbies such as gardening or rambling.

Within the workplace, there are fewer opportunities for increasing activity levels, but stairs can be used instead of the lift and people can walk to speak to colleagues rather than using the phone or email.

Below are some examples of the amount of energy expended over a period of 30 minutes for a selection of activities:. If you have a more general query, please contact us. Please note that advice provided on our website about nutrition and health is general in nature.

A negative energy balance over time leads to weight loss. Conversely, when we consume more calories per day than we use through physical activity, we gain weight.

Energy Balance and Obesity: Over a prolonged period, we may develop obesity. Obesity increases our risk of stroke, heart attack and, in more serious cases, can lead to organ failure.

That means we should consume energy our bodies need and also engage in a healthy level of physical activity. You can engage in minutes of moderate-intensity aerobic activity in a single session or over a few sessions by setting aside some days of the week for exercise.

Remember, it is important that you keep track and balance your energy intake calories consumed and energy output calories burned through exercising to achieve and maintain a healthy weight.

A healthy year old girl, weighing at 60kg, will have to balance her regular food intake with any of these activities: an hour of badminton or fast-paced modern dance; or an hour and a half of leisurely cycling a week.

When it comes to dieting and weight loss, it is really a game of balancing the food you eat and the amount of physical activity you engage in. Most importantly, it is an ideal and healthier way to do so as well! View More Programmes.

Related: Weight Management What Is Energy Balance? The only equation for diets is the Energy Balance Equation. Examples include:. Basal metabolic rate does not include the energy required for digestion or physical activity.

If a person is sedentary or moderately active, BMR is the largest component of energy expenditure, making up about 60 to 75 percent of total energy output. For example, a sedentary person might need about calories in a day, with about of them being for BMR.

Components of energy expenditure and their percent contribution to the total in sedentary to moderately active people.

BMR can vary widely among individuals. This means that a muscular person expends more energy than a person of similar weight with more fat. Likewise, increasing your muscle mass can cause an increase in your BMR. However, skeletal muscle at rest only accounts for about 18 percent of the total energy expended by lean mass.

Most is used to meet the energy needs of vital organs. The liver and brain, for example, together account for nearly half of the energy expenditure by lean mass.

Energy expenditure of organs. BMR depends not only on body composition but also on body size, sex, age, nutritional status, genetics, body temperature, and hormones Table 9. People with a larger frame size have a higher BMR simply because they have more mass.

On average, women have a lower BMR than men, because they typically have a smaller frame size and less muscle mass. As we get older, muscle mass declines, and therefore BMR declines as well. Nutritional status also affects basal metabolism.

If someone is fasting or starving, or even just cutting their caloric intake for a diet, their BMR will decrease. This is because the body attempts to maintain homeostasis and adapts by slowing down its basic functions BMR to help preserve energy and balance the decrease in energy intake.

This is a protective mechanism during times of food shortages, but it also makes intentional weight loss more difficult.

Factors That Increase BMR. Factors That Decrease BMR. Higher lean body mass. Lower lean body mass. Larger frame size. Smaller frame size. Younger age. Older age. Male sex. Female sex. Stress, fever, illness. Starvation or fasting. Pregnancy or lactation. Stimulants such as caffeine and tobacco.

Table 7. Factors that Impact BMR. This is the energy needed to digest, absorb, and store the nutrients in foods. It accounts for 5 to 10 percent of total energy expenditure and does not vary greatly amongst individuals. Physical activity is another important way the body expends energy.

Physical activity usually contributes anywhere from 15 to 30 percent of energy expenditure and can be further divided into two parts:. EAT is planned, structured, and repetitive physical activity with the objective of improving health participating in a sport like soccer or strength training at the gym, for example.

NEAT is the energy expenditure for unstructured and unplanned activities. This includes daily-living activities like cleaning the house, yard work, shopping, and occupational activities. NEAT also includes the energy required to maintain posture and spontaneous movements such as fidgeting and pacing.

NEAT can vary by up to 2, calories a day for two people of similar size, according to Dr. James Levine, the Mayo Clinic researcher who first coined the term. NEAT may be an important component of obesity, and is currently an area of research.

The brain specifically the hypothalamus is the main control center for hunger and satiety. There is a constant dialogue between our brains and gastrointestinal tracts through hormonal and neural signals, which determine if we feel hungry or full. Nutrients themselves also play a role in influencing food intake, because the hypothalamus senses nutrient levels in the blood.

When nutrient levels are low, the hunger center is stimulated. Conversely, when nutrient levels are high, the satiety center is stimulated.

The values for the three days were summed up and divided by three to obtain the mean daily energy intake. The mean values were used in statistical analysis.

PAL was determined with WHO global physical activity questionnaire that provided detailed report of types, intensity, frequency and duration in minutes of all physical activities exercise and non-exercise performed daily for three 3 consecutive days by the respondents [ 14 , 20 ].

Physical activity level factor of 1. Relationships between the outcome and exposure variables were assessed at both the binary and multivariate logistic regression. After examining the individual effects of the above 14 exposure variables at the binary level, they were entered simultaneously into the multivariate logistic model to evaluate the effect of each of the covariates on the outcome variable when other covariates are held constant.

Crude and adjusted odds ratios were reported for each of the covariate evaluated. Data collected were entered into Microsoft excel, validated, cleaned and sorted before being transported into IBM Statistical Product and Service Solutions version 21 computer software for descriptive and inferential statistical analysis.

Descriptive statistics frequencies and percentages was used for general characteristics, anthropometric and physical activity levels of the adults. Chi square test was used to evaluate the relationship between categorical variables anthropometric parameters and physical activity level of the respondents by age and sex as well as the relationship of these parameters with energy intake, expenditure and balance.

Means and standard deviations were used for energy intake, expenditure and balance. T-test was used to assess relationships between energy intake, expenditure and balance, and sex, waist circumference and waist hip ratio.

Whereas analysis of variance was used to compare the energy parameters among four age groups of the adults and assess the relationship of mean energy intake, expenditure and balance with anthropometric parameters and physical activity level. Binary logistic regression analysis was employed to evaluate associations between the outcome variable and the predictor variables.

Since binary logistic regression analysis does not control confounding effects, multivariate logistic regression analysis was conducted to correct for simultaneous effects of multiple factors and control the effects of confounding variables on the response variable.

The adjusted odds ratios were used to define the independent strength of the associations. Mean age years of the respondents was Table 1 presents the general characteristics of the respondents. More than half About thirty-five percent Secondary and tertiary education were attained by Majority of the respondents were engaged in an occupation Most of the respondents More than half of the respondents did not consume alcohol Anthropometric parameters, physical activity level, energy intake, expenditure and balance of the respondents by sex and age are shown in Table 2.

Female energy intake contributed Energy balance was positive among Figure 1 shows the percentage contributions of carbohydrate, protein and fat to the energy intakes of the adults by sex and age. Carbohydrate The 30—34 year-olds had the highest carbohydrate contribution Percentage contributions of carbohydrate, protein and fat to energy intake of the adults by sex and age.

Respondents with obesity had the highest energy intake Those with abdominal obesity had higher energy intake Table 4 shows the factors associated with energy balance of the respondents.

Respondents less than 30 years had nearly 3 times higher likelihood AOR: 2. Those who were not engaged in any occupation were 2 times more likely to have positive energy balance than those who were engaged in an occupation AOR: 2.

Though not significant, being a male AOR: 1. The likelihood of having positive energy balance decreased as body mass index increased though this did not attain significant proportions. This study which assessed the energy intake, energy expenditure and energy balance of young adults 20—39 years and examined factors associated with their energy balance was conducted in southeast Nigerian urban setting.

While Hattingh et al. The mean energy intake of males reported in this study is similar to Fyfe et al. According to Bennette et al. This is in line with the findings of this study in which male intake contributed only This means that other nutrient requirements will also not be met because all other nutrients must be provided within the quantity of food required to fulfil the energy requirements [ 29 ].

Energy intake reported in this study may be functions of portion sizes and diet composition. Fatty foods and diets contribute more to energy intake than carbohydrate and protein. A study also reported a higher percentage contribution from fat and less from carbohydrate and protein to energy intake [ 24 ].

According to Sudo et al. Females have been reported to consume foods more times during the day and uncontrollably too [ 31 ]; this may be responsible for the higher energy intake observed among them though relationship with male intake was not significant.

Mean energy expenditure of the males was significantly higher than that of the females. This is in line with the report of Redman et al. This higher energy expenditure in males could be attributed to larger muscle mass. Contrary to the findings of other researchers [ 24 , 27 ] on energy balance, this study reported positive energy balance among males and females raising concerns over weight gain if sustained.

Very small differences have been shown to lead to important gains in weight over time [ 33 ]. The positive energy balance of most of the respondents in this study may have contributed to the high prevalence of overweight and obesity among them.

The higher mean energy balance among females implies possible weight gain in the face of low energy expenditure. That up to Multivariate logistic regression analysis showed that respondents who were less than 30 years were more likely to have positive energy balance than those aged 30 years and above.

This may be a consequence of consumption of energy dense foods and beverages coupled with newly gained socioeconomic independence to make food choices. Livingstone et al. The likelihood of having positive energy balance increased by 2 among those who were not engaged in any occupation. This was attributed to low physical activity.

Being engaged in an occupation increases energy expenditure though research has shown reduction in occupation related energy expenditure and reported that increases observed in fat percentage and body mass index are independent of occupation [ 35 , 36 ].

Those not engaged in any occupation do not benefit from any occupation related activity and therefore, more likely to have low physical activity level which leads to positive energy balance, sustained weight gains and consequences of obesity. Though not significant, respondents who eat outside their homes were almost 2 times more likely to have positive energy balance.

Most foods consumed outside homes are fast foods and fast food consumers have been reported to have higher mean energy, carbohydrate, protein and fat intakes than non-fast food consumers [ 37 ].

Fast foods are mainly energy dense nutrient-poor foods and beverages. It was not a surprise therefore that three or less times weekly snack consumption was associated with less likelihood of having positive energy balance than a higher consumption of above three times a week; though this is not significant.

Smoking of cigarette and other substances increased the risk of having positive energy balance by 2; this however did not reach significant proportions. In affirmation, a strong linear relationship was observed between smoking pattern and dietary energy density in current smokers with daily and non-daily smokers having significantly higher dietary energy density than non-smokers [ 38 ].

In a study to determine the effect of smoking status on total energy expenditure, the authors [ 39 ] reported no significant differences in total energy expenditure between smokers and non-smokers implying that the issue may lie with energy intake.

That smoking significantly reduced dietary calorie intake [ 40 ] was contrary to our findings and may be attributed to type, frequency and quantity of smoke inhaled. Interestingly, the likelihood of having positive energy balance decreased as body mass index increased showing that those with normal body mass index were more likely to have positive energy balance than those with overweight and obesity.

This may be attributed to lack of caution in consuming energy dense foods and drinks. People with normal BMI should, therefore, guard against excessive energy intake and low physical activity level as it may lead to weight gain and retention.

This study is not without limitations. Firstly, the study was limited to an urban area in southeast Nigeria which did not represent the whole of Nigeria.

Secondly, we did not use the doubly labelled water method which is the gold standard method to assess body metabolic rate and body composition of the adults was not assessed.

Thirdly, the study employed self-reported retrospective data on food intake and physical activity which may be associated with recall bias. Fourthly, portion sizes on which the energy intake was based was not presented. Lastly, in assessing the factors associated with energy balance, cause and effect associations could not be established through a cross sectional study.

This study showed higher female daily energy intake than male intake with lower daily energy expenditure than males. The overall energy balance was positive.

Age and occupation contributed to positive energy balance among the respondents. These findings are vital to planning nutrition and health education, and dietetic management of individuals prone to obesity.
