Data are from n = 9 subjects (7 females). For comparison data from before the VLCD are given for these subjects. Asterisks indicate P < 0.05 for comparison between "before" and "after" the preceding VLCD.
"% change" indicates the change relative to baseline level (i.e. after VLCD); FA, fatty acids; PUFA, polyunsaturated fatty acids; LCPUFA, long chain (i.e. ≥ C20) polyunsaturated fatty acids;
