Validity of resting energy expenditure predictive equations before and after an energy-restricted diet intervention in obese women.

Validity of resting energy expenditure predictive equations before and after an energy-restricted diet intervention in obese women.

<h4>Background</h4>We investigated the validity of REE predictive equations before and after 12-week energy-restricted diet intervention in Spanish obese (30 kg/m(2)>BMI<40 kg/m(2)) women.<h4>Methods</h4>We measured REE (indirect calorimetry), body weight, height, and f...
