WebEnergy Balance = energy intake – energy expenditure When an individual is in energy balance , energy intake equals energy expenditure, and weight should remain stable. Positive energy balance occurs when energy intake is greater than energy expenditure, usually resulting in weight gain. Negative energy balance Webenergy definition is given by the following equation: ∆ = ∆ −∆U H (PV)ˆ ˆ ˆ The term ∆(PV)ˆ can be rewritten as follows f f i i ∆ = −(PV) (P V PV )ˆ ˆ ˆ Where the sub index f refers to the final condition, and the sub index i to the initial condition of methanol. Inserting this equation into the equation for ∆Uˆ yields:
