The already reported diet-induced decline of BMI (−4.6 (4.3–4.9) kg/m2, Table S3) [24] was accompanied by improvement of estimates of liver steatosis (HSI: 46.5 (42.8–52.5) vs. 40.8 (37.3–46.0); p = 1.6 × 10−20) and insulin sensitivity (HOMA-IR, ISIClamp [23] and FFASupp) (Table 2). This evidence concerns the gene INS and fatty liver disease.
