Plasma insulin and glucagon levels were significantly lower in all treatment groups than in the HF group (p = 0.000 for all treatment groups vs. the HF group, Figure 3E; p = 0.000, p = 0.016, and p = 0.019 for the HF + Met group, the HF + LGZGH group, and the HF + LGZGL group, respectively, vs. the HF group, Figure 3F). Here, GCG is linked to hydrops fetalis.
