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.
When your energy intake is less than your energy output what results?
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. 7 A negative energy balance is sometimes called a calorie deficit.
How does diet affect energy expenditure?
Food intake induces changes in energy expenditure as a function of changes in body size and body composition. In addition, energy restriction induces an adaptive reduction of energy expenditure through a lowering of tissue metabolism and a reduction of body movement.
What happens when energy input exceeds energy output?
1: Energy is a balance between energy input and energy output. When one exceeds the other you will lose or gain 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.
When energy intake exceeds energy expenditure the result is?
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 is the meaning of energy expenditure?
Energy expenditure. The total energy cost of maintaining constant conditions in the body plus the energy cost of physical activities. Exercise.
What happens when you use more energy than you take 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.
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.
What happens when energy intake exceeds the body’s energy needs?
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 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.
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.
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.
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.
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).
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 happens if energy expenditure exceeds energy intake?
When energy expenditure exceeds energy intake, energy balance is negative and leads to weight loss.
What is a calorie deficit?
To lose weight, you need to eat and drink fewer calories than you burn. That's called a calorie deficit. If you take in more than calories than you burn, then you don't have a calorie deficit and you won't lose weight. There are two ways to raise your calorie deficit: changing what and how much you eat, and exercise.
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.
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).
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.
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 a calorie surplus?
A caloric surplus is when the number of calories that we consume is higher than the number of calories we burn.

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 causes hyperactivity?
Conditions that may lead to hyperactivity include: Attention deficit hyperactivity disorder (ADHD) Brain or central nervous system disorders. Emotional disorders.
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.
When food is consumed any excess energy is stored in the?
The excess energy from the food we eat is digested and incorporated into adipose tissue, or fatty tissue. Most of the energy required by the human body is provided by carbohydrates and lipids. As discussed in Chapter 3 "Carbohydrates", glucose is stored in the body as glycogen.
