Imagine your driving a looong way away. You know you can make it but only just. You have to drive carefully but the car is still going to ping and show you the reserve tank sign. But you know you can make it.

Your body is the same. It has a reserve tank that it can use BUT it still pings to tell you that the main tabk is getting low.

What is also very important is when you eat. Your body adapts to this. Say weekdays you eat at 7 AM everyday. Your body now expects fuel at 7AM, but it is saturday and you are being lazy or preoccupied, so no fuel, your body signals harder because fuel is instinctively important to it. I was on night shift and used to eat my last snack at 4 am. The 1st month after leaving night shift, I woke up every morning at 430 am with hunger pangs. It took me some zolpidem/ambien and another month to change my routine back.

What you should also know is, your body does not just need fuel but also proteins. This is why a lack of musculature is common in starved people, because you don’t need proteins just for gains, you need them for normal cell reproduction, red blood cell production, waste management, etc.
That is why proteins such as red meat, chicken, etc are so filling because our bodies know that if it doesn’t get any, it has to use muscles whoch compromises our ability to fight or flee.
