When a diet contains more energy than expended the excess energy?
When a diet contains more energy than expended the excess energy? The law of conservation of energy applies: If one takes in more energy than is expended over time one will gain weight insufficient energy intake results in weight loss as the body taps its energy stores to provide for immediate needs.
When energy intake is greater than energy output the body weight will quizlet?
Explain how energy balance is related to body weight. positive or negative energy balance will tell us if we are going to gain or lose weight. when our energy intake is less than our energy output and our weight decreases. when our energy intake is greater than our energy output and our weight increases.
When more calories are taken in than expended energy balance?
Positive energy balance is when the calories you take in is greater than the calories expended. Weight is gained and fat stores are increased. One pound of fat contains approximately 3500 calories. Negative energy balance: calories you take in is less than the calories expended.
What is the greatest portion of energy expenditure for most adults?
The body's BMR accounts for the largest amount of energy expended daily (50–80 per cent of your daily energy use). Thermic effect of food (also known as thermogenesis) – your body uses energy to digest the foods and drinks you consume and also absorbs, transports and stores their nutrients.
What happens when energy intake exceeds energy expenditure?
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).
What happens to excess energy in the body?
Summary. If we regularly eat more kilojoules than our body needs, the excess will be stored as body fat. Achieving or maintaining a healthy weight is all about balancing energy we take in and energy we burn.
When the energy you consume is less than the energy you expend what happens to your weight?
Weight loss occurs when you create a negative energy balance. That is, you burn more calories than you consume. When this imbalance occurs, your body burns stored energy (fat) in order to function and you lose weight.
When energy intake is greater than energy output the result is negative energy balance quizlet?
A positive energy balance occurs when your energy input is greater than your energy output. A negative energy balance is sometimes called a calorie deficit.
What happens when energy intake is less than energy expenditure?
Energy balance refers to the relationship of energy intake to energy expenditure and energy storage. Less energy expenditure than energy intake results in a positive energy balance and storage of energy primarily as body fat.
What is energy expenditure in nutrition?
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.
What increases energy expenditure?
You can increase your resting energy expenditure by gaining more muscle mass, limiting time spent in a calorie deficit, and being more physically active.
How does excess energy in the body become fat?
As applied to biology, it means that energy consumed by an organism has to be either converted to a useful form (metabolized), excreted or stored. Thus, if we take in more calories than we expend or excrete, the excess has to be stored, which means that we get fatter and heavier.
What does a high energy expenditure mean?
Definition. Energy expenditure refers to the amount of energy an individual uses to maintain essential body functions (respiration, circulation, digestion) and as a result of physical activity.
What is it called when you have too much energy?
Hyperactivity is caused by a feeling of needing to be active. Often it's described as feeling an extra rush of unused energy that you feel the desire to use.
How do I release excess energy?

What happens when the body uses more energy than the calories it takes in?
The amount of energy in an item of food or drink is measured in calories. When we eat and drink more calories than we use up, our bodies store the excess as body fat. If this continues, over time we may put on weight.
When energy intake is greater than energy expenditure weight is?
Positive energy balance Positive energy balance occurs when energy intake is greater than energy expenditure, usually resulting in weight gain. Negative energy balance is when energy intake is less than energy expenditure, usually resulting in weight loss. Energy intake is made up of the calories we consume from food and beverages.
What happen if you energy consumed is greater than energy expended or you have more food intake but less physical exertion?
Abstract. Overweight and obesity are often theorized using the energy balance equation. When energy intake (EI) is greater than energy expended this creates a positive energy balance and leads to weight gain, conversely when energy expenditure (EE) exceeds EI this creates a negative energy balance and weight loss.
What is expended energy?
Energy expenditure refers to the amount of energy an individual uses to maintain essential body functions (respiration, circulation, digestion) and as a result of physical activity.
What happens if energy expenditure exceeds energy intake?
When energy expenditure exceeds energy intake, energy balance is negative and leads to weight loss.
How is energy expended?
Total daily energy expenditure is determined by resting or basal metabolic rate (BMR), food-induced thermogenesis, and energy expended as a result of physical activity.
What occurs when a person eats in excess?
Overeating causes the stomach to expand beyond its normal size to adjust to the large amount of food. The expanded stomach pushes against other organs, making you uncomfortable. This discomfort can take the form of feeling tired, sluggish or drowsy. Your clothes also may feel tight, too.
When energy intake exceeds expenditure The result can be?
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).
What makes food hyper?
The best foods to boost energy include fiber or protein-rich snacks like oatmeal, eggs, and bananas. You can also boost your energy by staying hydrated or drinking a caffeinated beverage like coffee.
What is a hyperactive?
Hyperactivity means a person may seem to move about constantly, including in situations when it is not appropriate, or excessively fidgets, taps, or talks. In adults, hyperactivity may mean extreme restlessness or talking too much.
What occurs in the body when more calories are used for energy by the body than are consumed quizlet?
A calorie deficit is a moderate reduction in the total number of calories and occurs when more calories are used for energy by the body (calories out) than are consumed (calories in), resulting in burning of body fat, which leads to a loss of weight.
What does high metabolism mean?
If your metabolism is "high" (or fast), you will burn more calories at rest and during activity. A high metabolism means you'll need to take in more calories to maintain your weight. That's one reason why some people can eat more than others without gaining weight.
How does energy expenditure cause weight loss?
With negative energy balance, a high AT reduces the drive towards weight loss. By contrast, a low AT in response to overfeeding increases the metabolic drive to gain weight. In a given individual, both mechanisms add to efficient energy use to conserve body energy providing a so-called thrifty phenotype (32, 33).
What happens when we burn more energy than we take in?
When we regularly eat more kilojoules than our body needs, the spare energy is stored as fat. Eating as little as 100kJ extra each day (or burning 100kJ less by exercise), can lead to one kilogram of body fat creeping on over a single year.
What occurs when a person eats in excess quizlet?
What occurs when a person eats too much? Fat cells enlarge. Imagine that an adult consumes 500 excess kcalories each day for two weeks.
