Energy balance and healthy living -
Find out about how much physical activity adults and children should be doing on our page on physical activity recommendations. The Estimated Average Requirements EARs for energy for the UK population were originally set by the Committee on the Medical Aspects of Food and Nutrition Policy COMA in and were reviewed in by the Scientific Advisory Committee on Nutrition SACN because the evidence base had moved on substantially, and over the same period, the levels of overweight and obesity in the UK had risen sharply.
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:.

Health conditions Overweight, obesity and weight loss Energy balance and weight. Health professional. Enlarge Text A A. Energy intake and expenditure. Key points Energy is needed by the body to stay alive, grow, keep warm and move around.
Energy is provided by food and drink. It comes from the fat, carbohydrate, protein and alcohol the diet contains. Energy requirements vary from one individual to the next, depending on factors such as age, sex, body composition and physical activity level.
Energy expenditure is the sum of the basal metabolic rate the amount of energy expended while at complete rest , the thermic effect of food TEF, the energy required to digest and absorb food and the energy expended in physical activity. To maintain bodyweight, it is necessary to balance the energy derived from food with that expended in physical activity.
To lose weight, energy expenditure must exceed intake, and to gain weight, energy intake must exceed expenditure. Energy intake and expenditure A regular supply of dietary energy is essential for life and is required to fuel many different body processes.
What determines how much energy a person needs? Basal metabolic rate The basal metabolic rate BMR is the rate at which a person uses energy to maintain the basic functions of the body — breathing, keeping warm, and keeping the heart beating — when at complete rest.
A common misconception is that anorexia nervosa only affects young women, but it affects all genders of all ages. Antioxidants scavenge free radicals from the body's cells, and prevent or reduce the damage caused by oxidation.

How to be a healthy weight — balancing energy in and energy out Achieving or maintaining a healthy weight is all about balancing the energy we take in with the energy we burn energy out.
Tips for watching the energy you take in: enjoy a variety of foods from each of the five food groups in the amounts recommended watch your portion sizes — particularly foods and drinks that are high in kilojoules limit your intake of energy-dense or high-kilojoule foods and drinks check the kilojoules on the menu when eating out if you do have an energy-dense meal, choose food or drinks that have fewer kilojoules at other meals in the day.
Tips for watching the energy you burn: be active in as many ways as you can throughout the day — take the stairs instead of the lift, get off the bus a stop early and walk, break up sitting time at work exercise regularly — at least 30 minutes of moderately intense activity on most days do more activity when you eat more kilojoules.
Energy in — eating too many kilojoules When we regularly eat more kilojoules than our body needs, the spare energy is stored as fat.
Energy in — eating too few kilojoules When we regularly eat fewer kilojoules than our body needs our weight may decrease. Energy out — exercise to burn kilojoules When you are active, your body burns more energy kilojoules.
Find out more about physical activity Making practical changes to your energy balance Reducing the amount of kilojoules we eat and drink every day, or doing more exercise every day, even by small amounts, can all add up and make a difference.

Chapter 9: Energy Balance and Healthy Body Weight (Part 1)Energy balance and healthy living -
The total energy content of a food can be found by burning it and measuring how much heat is released. Foods with fewer calories per gram such as fruits, vegetables, low-fat soups, lean protein and fibre-rich foods have a relatively low energy density.
Basing your diet on foods which are lower in calories or have a lower energy density and eating foods which are high in calories or have a higher energy density less often and in small amounts, can help to control your overall calorie intake.
Some foods with a higher energy density such as oily fish, cheese, nuts, seeds and avocados contain healthier types of fat and other important nutrients meaning they can be consumed in moderate amounts as part of a healthy, balanced diet. Carbohydrate is the most important source of energy for the body because it is the main fuel for both your muscles and brain.
Sources of carbohydrates include starchy foods, like bread, rice, potatoes, pasta, pulses and breakfast cereals. Choose higher fibre and wholegrain versions of these where possible.
Higher intakes of fibre have been linked with a lower risk of getting diseases such as colorectal cancer, type 2 diabetes and heart disease. We also get energy from protein and fat and these form an important part of our diet too but we don't need to eat as much of these as carbohydrates.
The Eatwell Guide shows the ideal make-up of a healthy, balanced diet. You can find out more about the Eatwell Guide on our page on a healthy, balanced diet. Different people need different amounts of energy.
The amount needed to maintain a healthy weight depends on your basal metabolic rate BMR , which is the minimum amount of energy your body uses to maintain basic bodily functions like breathing and your heartbeat.
BMR varies from person to person depending on your age, body size, gender and genes. But we also use energy to digest food and for physical activity. Some activities use more energy than others. For example, running will use more energy than a gentle walk and rowing will use more energy than typing!
The more active you are, the more energy your body uses up. Your weight depends on the balance between how much energy you consume from food and drinks, and the total amount of energy that is used by your body.
When you eat or drink more energy than you use, you put on weight; if you consume less energy from your diet than you use, you lose weight; but if you eat and drink the same amount of energy as you use up, you are in energy balance and your weight remains the same.
It is important for your health to maintain a healthy weight. For more information on the sources used in this text, please contact us. Children need to balance energy in and out too, but they are also growing; thus, their extra energy needs must also be met.

Energy In What we eat and drink. Energy Out What we use up through daily living and physical activity. Children Children use energy just being children - running on the play yard or building block towers.
In other words, it focuses on balancing the energy calories you consume and the energy calories you burn through physical activity. To lose weight, the number of calories we consume must be less than the number of calories we burn. 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!
