Principle of Energy Balance

It states that the amount energy entering a body must be equal to the amount of energy leaving it ( plus any change in internal storage)

The first law of thermodynamics which states that energy can neither the created nor destroyed but can be transformed from one form to another

It is the relationship between energy in ( food calories taken into the body from food and drinks)and energy out ( calories being used for the daily enery requirement)

<ol> <li>Positive balance: it occurs when the energy intake is more than the energy expenditure ( thus making energy storage greater than 0 ). When this occurs the body sores the extra energy typically as fat. This process causes weight gain. 2. Negative energy balance: it occurs when energy expenditure is greater than energy intake ( thus energy storage is less than 0 ). When this occurs the bodyis uses existing fat to meet it's energy requirement. This process causes weight gain. 3. Equal balance: this occurs when energy intake isc equal to energy expenditure ( energy storage is equal to 0) ad weightvremains the sam</li> </ol> Signup and view all the answers
