Our results revealed that HFD significantly inhibited CRC HCT116 and HT-29 xenograft tumor growth in obesity-resistant BALB/c nude mice in comparison with a low-fat diet (LFD). HFD feeding did not induce increases in body weight, serum pro-inflammatory cytokines, and lipid accumulation in the liver and white adipose tissue (WAT) in nude mice.
