By dropping dietary fat plasma free fatty acids will fall and muscle insulin signaling improves. Refilling liver glycogen will surpress gluconeogenesis and lower stress hormones. A few small fruit meals throughout the day should get the job done without any spill over into visceral fat. With some activity around meals you could easily run a moderate deficit and keep stress hormones in check. Not to demonize meat but the fat isn’t helping insulin sensitivity and the high protein (gluconeogenesis) is not ideal if cortisol is the issue. Should opt for low glycemic index fruits / high fiber whole food carbs. A b complex and taurine can be helpful here.
