Your job is not suitable for fitness. There is a saying that muscle is 3 points for exercise and 7 points for resting and eating. The best rest time for fitness crowd is 10 hour. It is best to go to bed at 10 and get up at 8 am. Your working hours violate this principle. And you can't have a good rest during the day. So you are the most important part of hunger, so you can't rest. So even if you exercise, it won't have much effect.
