Another study increased basal concentrations of glucagon‐like peptide 1 (GLP‐1) with a HF diet (CP: 30.0 g/100 g DM; CF: 21.4 g/100 g DM; and carbohydrates: 39.4 g/100 g DM) when compared to a HC diet (CP: 25.9 g/100 g DM; CF: 9.9 g/100 g DM; and carbohydrates: 54.9 g/100 g DM) (Schauf et al., 2018). The gene discussed is GCG; the disease is hydrops fetalis.
