When energy intake is greater than energy expended the result is?
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.
Is the state in which energy intake is greater than energy expended?
When energy intake exceeds energy expenditure a state of positive energy balance develops. Thus, positive energy balance occurs when excessive overfeeding relative to energy requirements occurs, and the body subsequently increases its overall energy stores.
What is the greatest portion of energy expenditure for most adults?
It is the metabolic cost of maintaining the body at rest and accounts for 50-70% of total energy expenditure in most individuals. Total lean mass, especially muscle mass, is largely responsible for the BMR.
What does the body’s total daily energy expenditure include?
basal metabolism. … basal metabolism. The body’s total daily energy expenditure includes. basal metabolic rate, thermal effect of food, and effects of physical activity.
What is the main source of energy for the body?
Your body breaks down carbohydrates into glucose. Glucose, or blood sugar, is the main source of energy for your body’s cells, tissues, and organs. Glucose can be used immediately or stored in the liver and muscles for later use.
What factors affect energy balance?
There are three main groups of factors—homoeostatic, environmental and behavioural processes—that interact and influence steady-state body weight. Alterations in any of these factors will result in changes to this steady-state and could result in obesity.
How can I improve 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 is the relationship between energy balance and body weight?
Energy balance is achieved when intake of energy is equal to energy expended. Weight can be thought of as a whole body estimate of energy balance; body weight is maintained when the body is in energy balance, lost when it is in negative energy balance, and gained when it is in positive energy balance.
What is the biggest component of the body’s energy expenditure?
Daily energy expenditure is composed of three major components: 1) resting metabolic rate (RMR); 2) the thermic effect of feeding (TEF); and 3) the thermic effect of activity (TEA). RMR constitutes 60 to 75% of daily energy expenditure and is the energy associated with the maintenance of major body functions.
What is energy expenditure and physical activity?
Physical activity is defined as any bodily movement produced by skeletal muscles that results in energy expenditure. The doubly labeled water method for the measurement of total energy expenditure (TEE), in combination with resting energy expenditure, is the reference for physical activity under free-living conditions.
What is the best predictor of your basal metabolic rate?
Cunningham nicely demonstrated that Lean body Mass (LBM) i.e. muscle mass, was the single best predictor of BMR.
What is my energy expenditure?
Your Total Daily Energy Expenditure (TDEE) is an estimation of how many calories you burn per day when exercise is taken into account. It is calculated by first figuring out your Basal Metabolic Rate, then multiplying that value by an activity multiplier.
What is the difference between positive and negative energy balance?
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.
