Obesity in SCI occurs because of acute and ongoing positive energy balance, i.e., greater caloric intake than energy expenditure. Total Daily Energy Expenditure (TDEE) in SCI is reduced primarily because of muscular atrophy and diminished muscular contraction; pharmacological treatment of spasticity possibly reduces energy expenditure (EE) even further, but has not been evaluated to date. TDEE is comprised of three components: Basal Energy Expenditure (BEE), Thermic Effect of Activity (TEA) and Thermic Effect of Food (TEF). Of the three, BEE contributes the greatest amount (65-75% TDEE) and is the most sensitive to changes in spasticity.
