Balance Food and Activity

What is Energy Balance?

Energy is another word for "calories." Your energy balance is the balance of calories consumed through eating and drinking compared to calories burned through physical activity. What you eat and drink is ENERGY IN. What you burn through physical activity is ENERGY OUT.

You burn a certain number of calories just by breathing air and digesting food. You also burn a certain number of calories (ENERGY OUT) through your daily routine. For example, children burn calories just being students—walking to their lockers, carrying books, etc.—and adults burn calories walking to the bus stop, going shopping, etc. A chart of estimated calorie requirements for children and adults is available at the link below; this chart can help you maintain a healthy calorie balance.

An important part of maintaining energy balance is the amount of ENERGY OUT (physical activity) that you do. People who are more physically active burn morecalories than those who are not as physically active.

The same amount of ENERGY IN (calories consumed) and ENERGY OUT
(calories burned) over time = weight stays the same

More IN than OUT over time = weight gain
More OUT than IN over time = weight loss

Your ENERGY IN and OUT don't have to balance every day. It's having a balance over time that will help you stay at a healthy weight for the long term. Children need to balance their energy, too, but they’re also growing and that should be considered as well. Energy balance in children happens when the amount of ENERGY IN and ENERGY OUT supports natural growth without promoting excess weight gain.

That’s why you should take a look at the Estimated Calorie Requirement chart, to get a sense of how many calories (ENERGY IN) you and your family need on a daily basis.

Estimated Calorie Requirements

This calorie requirement chart presents estimated amounts of calories needed to maintain energy balance (and a healthy body weight) for various gender and age groups at three different levels of physical activity. The estimates are rounded to the nearest 200 calories and were determined using an equation from the Institute of Medicine (IOM).

• These levels are based on Estimated Energy Requirements (EER) from the IOM Dietary Reference Intakes macronutrients report, 2002, calculated by gender, age, and activity level for reference-sized individuals. "Reference size," as determined by IOM, is based on median height and weight for ages up to age 18 years of age and median height and weight for that height to give a BMI of 21.5 for adult females and 22.5 for adult males.
• Sedentary means a lifestyle that includes only the light physical activity associated with typical day-to-day life.
• Moderately active means a lifestyle that includes physical activity equivalent to walking about 1.5 to 3 miles per day at 3 to 4 miles per hour, in addition to the light physical activity associated with typical day-to-day life.
• Active means a lifestyle that includes physical activity equivalent to walking more than 3 miles per day at 3 to 4 miles per hour, in addition to the light physical activity associated with typical day-to-day life.
• The calorie ranges shown are to accommodate needs of different ages within the group. For children and adolescents, more calories are needed at older ages. For adults, fewer calories are needed at older ages.

Energy Balance in Real Life

Think of it as balancing your "lifestyle budget." For example, if you know you and your family will be going to a party and may eat more high-calorie foods than normal, then you may wish to eat fewer calories for a few days before so that it balances out. Or, you can increase your physical activity level for the few days before or after the party, so that you can burn off the extra energy.

The same applies to your kids. If they’ll be going to a birthday party and eating cake and ice cream—or other foods high in fat and added sugar—help them balance their calories the day before and/or after by providing ways for them to be more physically active.

Here's another way of looking at energy balance in real life.

Eating just 150 calories more a day than you burn can lead to an extra 5 poundsover 6 months. That’s a gain of 10 pounds a year. If you don't want this weight gain to happen, or you want to lose the extra weight, you can either reduce your ENERGY IN or increase your ENERGY OUT. Doing both is the best way to achieve and maintain a healthy body weight.

• Here are some ways to cut 150 calories (ENERGY IN):
  • Drink water instead of a 12-ounce regular soda
  • Order a small serving of French fries instead of a medium , or order a salad with dressing on the side instead
  • Eat an egg-white omelet (with three eggs), instead of whole eggs
  •  Use tuna canned in water (6-ounce can), instead of oil
• Here are some ways to burn 150 calories (ENERGY OUT), in just 30 minutes(for a 150 pound person):
  • Shoot hoops
  • Walk two miles
  • Do yard work (gardening, raking leaves, etc.)  
  • Go for a bike ride
  • Dance with your family or friend.

• Type 2 Diabetes

• Coronary Heart Disease and Stroke

• Metabolic Syndrome

• Cancer

• Sleep Apnea

• Osteoarthritis

• Gallbladder Disease

• Fatty Liver Disease

• Pregnancy Complications

How can I lower my health risks?

If you are overweight, losing as little as 5 percent of your body weight may lower your risk for several diseases, including coronary heart disease and type 2 diabetes. If you weigh 200 pounds, this means losing 10 pounds. Slow and steady weight loss of 1/2 to 2 pounds per week, and not more than 3 pounds per week, is the safest way to lose weight.

To lose weight, or to maintain weight loss, you will likely need to do more than 30 minutes of moderate physical activity daily.

Healthy Weight - it's not a diet, it's a lifestyle!

Getting Started

Losing weight takes more than desire. It takes commitment and a well-thought-out plan. Here's a step-by-step guide to getting started.

Step 1: Make a commitment.

Making the decision to lose weight, change your lifestyle, and become healthier is a big step to take. Start simply by making a commitment to yourself. Many people find it helpful to sign a written contract committing to the process. This contract may include things like the amount of weight you want to lose, the date you'd like to lose the weight by, the dietary changes you'll make to establish healthy eating habits, and a plan for getting regular physical activity. 

Writing down the reasons why you want to lose weight can also help. It might be because you have a family history of heart disease, or because you want to see your kids get married, or simply because you want to feel better in your clothes. Post these reasons where they serve as a daily reminder of why you want to make this change.

Step 2: Take stock of where you are.

Consider talking to your health care provider. He or she can evaluate your height, weight, and explore other weight-related risk factors you may have. Ask for a follow-up appointment to monitor changes in your weight or any related health conditions. 

Keep a "food diary" for a few days, in which you write down everything you eat. By doing this, you become more aware of what you are eating and when you are eating. This awareness can help you avoid mindless eating. 

Next, examine your current lifestyle. Identify things that might pose challenges to your weight loss efforts. For example, does your work or travel schedule make it difficult to get enough physical activity? Do you find yourself eating sugary foods because that's what you buy for your kids? Do your coworkers frequently bring high-calorie items, such as doughnuts, to the workplace to share with everyone? Think through things you can do to help overcome these challenges.

Finally, think about aspects of your lifestyle that can help you lose weight. For example, is there an area near your workplace where you and some coworkers can take a walk at lunchtime? Is there a place in your community, such as a YMCA, with exercise facilities for you and child care for your kids?

Step 3: Set realistic goals.

Set some short-term goals and reward your efforts along the way. If your long-term goal is to lose 40 pounds and to control your high blood pressure, some short-term eating and physical activity goals might be to start eating breakfast, taking a 15 minute walk in the evenings, or having a salad or vegetable with supper. 

Focus on two or three goals at a time. Great, effective goals are —

·         Specific

·         Realistic

·         Forgiving (less than perfect)

For example, "Exercise More" is not a specific goal. But if you say, "I will walk 15 minutes, 3 days a week for the first week," you are setting a specific and realistic goal for the first week. 

Remember, small changes every day can lead to big results in the long run. Also remember that realistic goals are achievable goals. By achieving your short-term goals day-by-day, you'll feel good about your progress and be motivated to continue. Setting unrealistic goals, such as losing 20 pounds in 2 weeks, can leave you feeling defeated and frustrated. 

Being realistic also means expecting occasional setbacks. Setbacks happen when you get away from your plan for whatever reason – maybe the holidays, longer work hours, or another life change. When setbacks happen, get back on track as quickly as possible. Also take some time to think about what you would do differently if a similar situation happens, to prevent setbacks.

Keep in mind everyone is different – what works for someone else might not be right for you. Just because your neighbor lost weight by taking up running, doesn't mean running is the best option for you. Try a variety of activities – walking, swimming, tennis, or group exercise classes to see what you enjoy most and can fit into your life. These activities will be easier to stick with over the long term. 
 

Step 4: Identify resources for information and support.

Find family members or friends who will support your weight loss efforts. Making lifestyle changes can feel easier when you have others you can talk to and rely on for support. You might have coworkers or neighbors with similar goals, and together you can share healthful recipes and plan group exercise. 

Joining a weight loss group or visiting a health care professional such as a registered dietitian, can help.

Step 5: Continually "check in" with yourself to monitor your progress.

Revisit the goals you set for yourself (in Step 3) and evaluate your progress regularly. If you set a goal to walk each morning but are having trouble fitting it in before work, see if you can shift your work hours or if you can get your walk in at lunchtime or after work. Evaluate which parts of your plan are working well and which ones need tweaking. Then rewrite your goals and plan accordingly. 

If you are consistently achieving a particular goal, add a new goal to help you continue on your pathway to success.

Reward yourself for your successes! Recognize when you're meeting your goals and be proud of your progress. Use non-food rewards, such as a bouquet of freshly picked flowers, a sports outing with friends, or a relaxing bath. Rewards help keep you motivated on the path to better health.

Childhood Obesity Facts

• Childhood obesity has more than doubled in children and tripled in adolescents in the past 30 years.
• The percentage of children aged 6–11 years in the United States who were obese increased from 7% in 1980 to nearly 18% in 2010. Similarly, the percentage of adolescents aged 12–19 years who were obese increased from 5% to 18% over the same period.
• In 2010, more than one third of children and adolescents were overweight or obese.
• Overweight is defined as having excess body weight for a particular height from fat, muscle, bone, 
• water, or a combination of these factors. Obesity is defined as having excess body fat.
• Overweight and obesity are the result of “caloric imbalance”—too few calories expended for the amount of calories consumed—and are affected by various genetic, behavioral, and environmental factors.

Health Effects of Childhood Obesity

^{Childhood obesity has both immediate and long-term effects on health and well-being.}

Immediate health effects:

• Obese youth are more likely to have risk factors for cardiovascular disease, such as high cholesterol or high blood pressure. In a population-based sample of 5- to 17-year-olds, 70% of obese youth had at least one risk factor for cardiovascular disease.⁷
• Obese adolescents are more likely to have prediabetes, a condition in which blood glucose levels indicate a high risk for development of diabetes.^8,9
• Children and adolescents who are obese are at greater risk for bone and joint problems, sleep apnea, and social and psychological problems such as stigmatization and poor self-esteem.^5,6,10

Long-term health effects:

• Children and adolescents who are obese are likely to be obese as adults^11-14 and are therefore more at risk for adult health problems such as heart disease, type 2 diabetes, stroke, several types of cancer, and osteoarthritis.⁶  One study showed that children who became obese as early as age 2 were more likely to be obese as adults.¹²
• Overweight and obesity are associated with increased risk for many types of cancer, including cancer of the breast, colon, endometrium, esophagus, kidney, pancreas, gall bladder, thyroid, ovary, cervix, and prostate, as well as multiple myeloma and Hodgkin’s lymphoma.¹⁵

Prevention

• Healthy lifestyle habits, including healthy eating and physical activity, can lower the risk of becoming obese and developing related diseases.⁶
• The dietary and physical activity behaviors of children and adolescents are influenced by many sectors of society, including families, communities, schools, child care settings, medical care providers, faith-based institutions, government agencies, the media, and the food and beverage industries and entertainment industries.
• Schools play a particularly critical role by establishing a safe and supportive environment with policies and practices that support healthy behaviors. Schools also provide opportunities for students to learn about and practice healthy eating and physical activity behaviors.

10 FACTS ON OBESITY

10 FACTS ON OBESITY

1-Overweight and obesity are defined as "abnormal or excessive fat accumulation that may impair health"

Body mass index (BMI) – the weight in kilograms divided by the square of the height in meters (kg/m2) – is a commonly used index to classify overweight and obesity in adults. WHO defines overweight as a BMI equal to or more than 25, and obesity as a BMI equal to or more than 30.

2-More than 1.4 billion adults were overweight in 2008, and more than half a billion obese

In 2008, more than 1.4 billion adults were overweight and more than half a billion were obese. At least 2.8 million people each year die as a result of being overweight or obese. The prevalence of obesity has nearly doubled between 1980 and 2008. Once associated with high-income countries, obesity is now also prevalent in low- and middle-income countries.

3-Globally, over 40 million preschool children were overweight in 2008

Childhood obesity is one of the most serious public health challenges of the 21st century. Overweight children are likely to become obese adults. They are more likely than non-overweight children to develop diabetes and cardiovascular diseases at a younger age, which in turn are associated with a higher chance of premature death and disability.

4-Overweight and obesity are linked to more deaths worldwide than underweight

65% of the world's population live in a country where overweight and obesity kills more people than underweight. This includes all high-income and middle-income countries. Globally, 44% of diabetes, 23% of ischaemic heart disease and 7–41% of certain cancers are attributable to overweight and obesity.

5-For an individual, obesity is usually the result of an imbalance between calories consumed and calories expended

An increased consumption of highly calorific foods, without an equal increase in physical activity, leads to an unhealthy increase in weight. Decreased levels of physical activity will also result in an energy imbalance and lead to weight gain

6-Supportive environments and communities are fundamental in shaping people’s choices and preventing obesity

Individual responsibility can only have its full effect where people have access to a healthy lifestyle, and are supported to make healthy choices. WHO mobilizes the range of stakeholders who have vital roles to play in shaping healthy environments and making healthier diet options affordable and easily accessible.

7-Children's choices, diet and physical activity habits are influenced by their surrounding environment

Social and economic development as well as policies in the areas of agriculture, transport, urban planning, environment, education, food processing, distribution and marketing influence children's dietary habits and preferences as well as their physical activity patterns. Increasingly, these influences are promoting unhealthy weight gain leading to a steady rise in the prevalence of childhood obesity.

8-Eating a healthy diet can help prevent obesity

People can:
1) maintain a healthy weight
2) limit total fat intake and shift fat consumption away from saturated fats to unsaturated fats
3) increase consumption of fruit, vegetables, pulses, whole grains and nuts
4) limit the intake of sugar and salt.

9-Regular physical activity helps maintain a healthy body

People should engage in adequate levels of physical activity throughout their lives. At least 30 minutes of regular, moderate-intensity physical activity on most days reduces the risk of cardiovascular disease, diabetes, colon cancer and breast cancer. Muscle strengthening and balance training can reduce falls and improve mobility among older adults. More activity may be required for weight control.

10-Curbing the global obesity epidemic requires a population-based multisectoral, multi-disciplinary, and culturally relevant approach

WHO's Action Plan for the Global Strategy for the Prevention and Control of Noncommunicable Diseases provides a roadmap to establish and strengthen initiatives for the surveillance, prevention and management of noncommunicable diseases, including obesity.
