Fat oxidation was significantly suppressed by insulin during the euglycemic clamp, for both African–American and white women, after both the LF (p<0.001) and HF (p<0.001) diets (figure 2A), with no significant insulin by race interaction (figure 2B) on either diet (p=0.27 and p=0.28, respectively). Here, INS is linked to hydrops fetalis.
