When energy intake exceeds energy expenditure, a state of positive energy balance occurs and the consequence is an increase in body mass, of which 60 to 80 percent is usually body fat (2).
How does energy imbalance cause obesity?
Conclusion. Energy intake that exceeds energy expenditure is the main driver of weight gain. The quality of the diet may exert its effect on energy balance through complex hormonal and neurological pathways that influence satiety and possibly through other mechanisms.
How does energy balance affect body weight?
A positive energy balance, in which energy intake exceeds expenditure causes weight gain, with 60–80 % of the resulting weight gain being attributable to body fat. In negative energy balance, when energy expenditure exceeds intake, the resulting loss in body mass is also accounted for by 60–80 % body fat.
How does energy imbalance including the role of physical activity lead to weight gain and obesity?
Physical activity increases people’s total energy expenditure, which can help them stay in energy balance or even lose weight, as long as they don’t eat more to compensate for the extra calories they burn. Physical activity decreases fat around the waist and total body fat, slowing the development of abdominal obesity.
What is the result of energy imbalance?
A key concept is that energy balance is a long-term, rather than a short-term, goal. Two important consequences of energy imbalance for adolescents are obesity and undernutrition. Obesity is a chronic metabolic disease resulting from an imbalance between energy intake and energy output.

What happens if your energy output exceeds your energy intake?
When energy expenditure exceeds energy intake, energy balance is negative and leads to weight loss. When intake equals expenditure, equilibrium results and body fat is maintained, regardless of whether the body weight is at, above, or below normal.
How do I restore my energy balance?
Energy Balance in Real Life
- 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.
What are the consequences of not being in energy balance?
A severe negative energy balance can lead to a decline in metabolism, decreases in bone mass, reductions in thyroid hormones, reductions in testosterone levels, an inability to concentrate, and a reduction in physical performance. Yet a negative energy balance does lead to weight loss.
What is energy in energy out?
“Energy in” is the energy you put into your body in the form of calories from foods and beverages. “Energy out” is the calories you burn for basic bodily functions such as your heart beating or breathing and from physical activity.
Why is it important to reduce obesity?
A primary reason that prevention of obesity is so vital in children is because the likelihood of childhood obesity persisting into adulthood increases as the child ages. This puts the person at high risk of diabetes, high blood pressure, and heart disease.
How does exercise affect your mental and emotional well being?
Research shows that people who exercise regularly have better mental health and emotional wellbeing, and lower rates of mental illness. Taking up exercise seems to reduce the risk of developing mental illness. It also seems to help in treating some mental health conditions, like depression and anxiety.
How does excess body fat affect health?
High blood pressure, high cholesterol, and high blood sugar on top of excess body fat can make the blood vessels that carry blood to the heart become hard and narrow. Hardened arteries, also called atherosclerosis, can increase the risk of heart attack and stroke.
What does energy balance depend on?
BMR is dependent on body size, body composition, sex, age, nutritional status, and genetics. People with a larger frame size have a higher BMR simply because they have more mass. Muscle tissue burns more calories than fat tissue even while at rest and thus the more muscle mass a person has, the higher their BMR.
What is the importance of energy balance?
“Simply put, calories in equals calories out.” Energy balance is important. When you consume too much energy and burn too little, your body stores that excess energy as body fat. And being overweight increases your risk for several cancers, including colon, pancreatic, endometrial and post-menopausal breast cancer.
What is a negative energy balance?
Condition in which less energy (food) is taken in than is expended in metabolism, resulting in a decrease in body weight. From: negative energy balance in The Oxford Dictionary of Sports Science & Medicine »
