Have even distribution of protein across 4-5 meals/snacks and with your main meals have plenty of starch/sugar and fiber. Like have your 3 square meals a day as actual food with the macros you need, maybe a yogurt or something with good protein as a snack, and then have slow digesting protein an hour or so before bed like some meat or something casein heavy like cottage cheese or a protein pudding. Keep your micros high, especially your b vitamins, and don't skimp on your electrolytes. Use but don't abuse caffeine as well. Only train with about half as much volume as it took for you to build muscle on a bulk since you don't have as many resources for recovery to grow. And lastly, sleep very well and don't skimp on the hours. When you're well rested, not only will you have more energy, your executive function is better so you'll have more willpower, and hunger won't feel as intense
