Seems to be confirmed on 1.8.9 server after changing from Peaceful to Easy. No indication of food loss and then suddenly starving, then once you hit 5 hearts (from starvation on Easy) and the food bar is refilled, you have to take more damage to eat (regardless of what amount, it'll just refill the bar quickly like before) and only then will your bar actually be full and you can regenerate hearts.
Will add I'm using minecraft-server1.8.9 exe to run the server (so not LAN)
