Coffee consum ption prevents obesity-related comorbidities and attenuates brown adipose tissue whitening in high-fat diet-fed mice

This study aimed to evaluate the preventive and therapeutic effects of coffee consum ption on molecular changes and adipose tissue remodeling in a murine model of high-fat diet-induced obesity. Three-month-old C57BL/6 mice were initially divided into three groups, namely, control (C), high-fat (HF), and coffee prevention (HF-CP) groups, and the HF group was subdivided at the end of the 10th week into two subgroups, an HF group and a coffee treatment (HF-CT) group; thus, a total of four groups were investigated at the 14th week of the experiment. The HF-CP group had lower body mass than the HF group ( -7%, P < .05) and a better distribution of adipose tissue. Both groups that received coffee (HF-CP and HF-CT) showed improved glucose metabolism compared with the HF group. Coffee consumption also attenuated adipose tissue inflammation and showed decreased macrophage infiltration and lower IL-6 levels compared with the HF group (HF-CP: -337% %, P < .05; HF-CT: -275%, P < .05). Hepatic steatosis and inflammation were attenuated in the HF-CP and HF-CT groups. The HF-CP group showed more pronounced expression of genes involved in adaptive thermogenesis and mitochondrial biogenesis (PPAR gamma, Prdm16, Pcg1 alpha, beta 3-adrenergic receptor, Ucp-1, and Opa-1) than the other experimental groups. Preventive coffee consumption associated with a high-fat diet ameliorates the metabolic profile related to the development of obesity and its comorbidities. (c) 2023 Elsevier Inc.

Automated summary

This study aimed to evaluate the preventive and therapeutic effects of coffee consumption on molecular changes and adipose tissue remodeling in a murine model of high-fat diet-induced obesity. The results showed that the coffee prevention group had lower body mass and a better distribution of adipose tissue compared to the high-fat group. Both groups that received coffee showed improved glucose metabolism and attenuated adipose tissue inflammation. Coffee consumption also attenuated hepatic steatosis and inflammation. Preventive coffee consumption associated with a high-fat diet ameliorates the metabolic profile related to the development of obesity and its comorbidities.
