Insulin sensitivity computed as the glucose disposal rate per kg of FFM and divided by the steady-state insulin level (M/I) was not significantly decreased by the diet in the African–American (0.06±0.01 vs 0.07±0.01, for LF vs HF diet, respectively, p=0.40) or in the white women (0.09±0.01 vs 0.10±0.01, for LF vs HF diet, respectively, p=0.09). Here, INS is linked to hydrops fetalis.
