It has been found that the use of the plant terpenoid compound ginsenoside Rb1 reduces body weight gain, the accumulation of fat mass, and the expression of inflammatory markers, SOCS3 and PTP1B, in addition to reducing the deterioration of the signalling pathway JAK2-STAT3 and central leptin sensitivity due to obesity induced by high fatty acid diets [89,90]. This evidence concerns the gene SOCS3 and obesity disorder.
