+1 for the Endurance Diet. I’m not even half way through the book and already sold on the overall philosophy. Get rid of the “easy” stuff which, for me, is added sugar and low-quality snacks. (This thread has many good suggestions in it.)
Secondly, add weight training if you’re not already doing it. There’s a fair amount of science that correlates lifting to weight loss.
Finally, do those endurance rides fasted if you can. If needed work up to it. At least for me, once I get going, any initial hunger pangs I feel go away after 15-20 minutes plus drinking water.
