tively impacts markers of obesity, which may be linked to the ghrelin- ergic effects previously demonstrated [37]. Specifically, we found that in the preclinical mouse model of obesity, the supplementation with B. longum APC1472 significantly reduced fat depots and body weight gain in HFD-fed mice independent of energy intake. Furthermore, B. longum APC1472 significantly reduced circulating leptin levels in HFD-fed

mice, which is in line with the reduction in fat depot size as leptin is released into the bloodstream in proportion to body fat mass [75]. No- tably, circulating levels of leptin were increased in HFD-fed mice com- pared to LFD-fed mice with no alterations in leptin receptor hypothal- amic expression, suggesting no alterations in leptin sensitivity, as has been previously reported in obesity [76]. No changes were observed in
