we found that the formula-fed , very-low-birth-weight infant who gained weight comparably to the fetus retained the same amount of protein ( 1.92 +/- 0.1 g per kilogram of body weight per day ) but accumulated fat at a rate of 5.4 +/- 0.3 g per kilogram per day - about three times that in the fetus , as confirmed by increased skin-fold thickness .
