Agree. Are you implementing intermittent fasting? Having a shorter feeding period may help retain energy. 

Also I found a 3 day fast once a month gives a bot of a reset and I do t need as much sustenance. 

Im 5’9 and maintain 170-180 usually right around 175. 

 Intermittent fasting was a big part of my diet for years when I was maintaining on carnivore. I actually need to eat more often in smaller amounts right now.  

 Keep on the path. The more you experience and experiment the more you’ll learn your body.
