Answer:
Body weight is relatively stable during neutral energy balance, whereas body weight increases during positive energy balance.
Explanation:
Generally, when the quantity of energy input ( from food substance , is balance by the quantity of energy released from the body over an extended period of time, then there is neutral energy balance in the organism.
When an individual consumes too much quantity of food,(over feeding) or engaged in a sedentary lifestyle, so that higher quantity of energy from food intake is stored in the body more than is expended or burnt.This leads to storage of excess food as fats in the adipose tissues.The type of Energy gained by the body is call positive energy balance.
However, when the energy intake or calorie intake is lesser than the energy expenditure or calorie lost, negative energy balance occurs.This may be caused by different medical conditions.
Consequently, from above body weight will be relatively stable in Neutral energy balance because of calorie balance, while more energy will be conserved in positive energy balance because of excess energy from excess calorie.
