At base line and every two months thereafter, her height was measured with the same stadiometer and her body composition was measured
by dual - energy x-ray absorptiometry (QDR 1000W, Hologic, Waltham,
Mass.) to determine the bone mineral
mass and the amounts of fat and
lean soft
tissue.11 Spontaneous energy intake was measured with the use of a standardized test meal (containing 1670 kcal of energy) given at noon, after the patient had been fasting since breakfast.
Clearly, this is an incorrect statement since catabolism of
lean body
mass is reduced
by ketone bodies (possibly through suppression of the activity of the branched - chain 2 - oxo acid dehydrogenase), which and probably explains the preservation of
lean tissue observed during very - low - carbohydrate diets.
