When the diet contains more energy than is expended the excess energy

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 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 intake?

However, daily energy requirements vary widely from one individual to the next. This is due to factors such as sex, body size, bodyweight, climate and physical activity levels. Energy is obtained, from the food and drink we consume, by oxidation of carbohydrate, fat, protein and alcohol, known as macronutrients.

How can I improve my energy balance?

  3. Eat an egg-white omelet (with three eggs), instead of whole eggs.

How is energy balance calculated?

The complete energy equation looks like this:

  1. Energy balance = energy input – energy output.
  2. Weight gain = energy input > energy output.
  3. Weight loss = energy input < energy output.

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 the recommended total calorie deficit per day for weight loss?

For most people, a calorie deficit of 500 calories per day is sufficient for weight loss and unlikely to significantly affect your hunger or energy levels (2). To create this calorie deficit, you need to know what your maintenance calories are.

What is the richest source of energy?

Carbohydrates are the body’s main source of energy. The fruit, vegetables, dairy, and grain food groups all contain carbohydrates.

What are the 3 sources of energy for the body?

Humans obtain energy from three classes of fuel molecules: carbohydrates, lipids, and proteins. The potential chemical energy of these molecules is transformed into other forms, such as thermal, kinetic, and other chemical forms.
