What happens then if you don’t eat for three days? Posternak breaks down each phase of what occurs with the meals you eat.
Most of the remaining glucose that is still flowing in your veins after six to ten hours of fasting will be converted to energy. By the tenth hour, you will be hungry and have a lack of energy if you have become used to consuming 3 meals a day or eating a high-carb diet frequently. After 2 hours, the feeling of hunger will go away, and your body will adjust to the new knowledge on its own.
Your body is going to keep using up its glycogen reserves and become more dependent on ketone bodies during twelve and sixteen hours of fasting. Due to your body’s inability to digest meals, you may be experiencing a cold right now. Your metabolism, cholesterol levels, and inflammatory levels will all improve.
Your body will initiate the catabolism process, an auto-recycling process that involves getting rid of any waste it detects, including broken proteins, germs, and unhealthy cells, after sixteen to eighteen hours of fasting.
