Counterpoint: have sleep for dinner. You're tired enough. By the time you wake up, you'll be less than 12 hours away from hitting the point where the hunger pangs start to get weaker. If you make it to 36 hours, they go away completely. Your body has at that point switched entirely to burning fat for energy and you will feel extra alert, focused, and energetic. Every physical activity you do prompts the release of human growth hormone to prevent muscle wastage, but your body does begin to break down damaged proteins all throughout itself, cannibalizing excess skin and malfunctioning cells. This is referred to as autophagy, and whatever reclaimed proteins don't get used to heal your muscles and joints will be metabolized via gluconeogenesis, providing your brain with all the glucose it needs to function. You will need to drink a lot more water, though, and you'll lose ~3lbs per day, so you probably will need to eat soon. But for now, your slavemasters will be briefly amused by your increased productivity, and the slum lord will appreciate that the money you didn't spend on calories will line its pockets.
