What happens when energy balance is negative?

In negative energy balance, when energy expenditure exceeds intake, the resulting loss in body mass is also accounted for by 60–80 \% body fat. It is commonly assumed that energy intake and energy expenditure can be independently modified, through changes in food intake and physical activity, to achieve energy balance.

Does negative energy balance result in weight loss?

Sustained negative energy balance will result in weight loss, with body composition changes similar for different dietary interventions if total energy and protein intake are equated. During periods of underfeeding, compensatory metabolic and behavioural responses occur that attenuate the prescribed energy deficit.

What happens to weight energy consumed is greater than energy expended?

When more energy is consumed than is needed for metabolism and physical activity, the excess is stored, primarily as adipose tissue. When energy expenditure exceeds energy intake, energy balance is negative and leads to weight loss.

How does weight affect energy requirements?

Body size and body composition are the determinants of resting energy expenditure. Higher weight results in higher energy requirement through a higher resting requirement because of a higher maintenance cost of a larger body.

What order do you lose body fat?

Fat loss or body mass loss in general is a 4 phase process:

1. Phase -1 – GLYCOGEN DEPLETION. Glycogen Depletion:
2. Phase -2 – FAT LOSS. This is the sweet spot for healthy weight loss.
3. Phase -3 – PLATEAU.
4. Phase -4 – METABOLIC RECOVERY.
5. All the Phases of Weight Management:

What happens when energy intake is high and energy demands are low?

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.
