Eating is something you have to do every single day to survive, yet there's actually a surprising number of changes that are enacted if you don't consume any food for up to 24 hours, as one shocking simulation details.
Most people across the world eat food at least three times a day, and often more if they engage in snacking in between meals, so the longest you'll ever go without eating is between your last meal of the day and your first when you wake up the day after.
This, depending on when you stop eating and start again, can often be anywhere between 12 and 16 hours, but you might be surprised to find out that there's a number of benefits that can be achieved when you let your body 'reset' for a little longer.
As reported by LADbible, one simulation shared by elevatemindhq on YouTube reveals this process, checking in on the body at several different hourly intervals to see what happens when you go longer periods across the day without eating.

Within and up to the first 12 hours without food, the simulation explains that your body burns through any glucose that it has stored, starting the transition from burning sugar to burning fat.
Things start to get really interesting at the 16-hour mark though, which is typically the longest that people go without eating on an average day. It is at this point that something 'remarkable' happens according to the simulation, as your body triggers what's known as autophagy.
This is understood to be the scientific process that which your body removes unnecessary or dysfunctional parts like organelles or proteins, and it's often referred to as your body's 'self-cleaning' process.
Once you reach the 18-hour mark your growth hormone levels will increase by around 300 percent, which accelerates the rate at which your body gets rid of fat and also preserves your muscle mass.
Just two hours later at the 20-hour period your insulin sensitivity is dramatically improved, which results in the enhancement of processing any nutrients when you next consume any food, making the times that you do eat far more efficient.
The simulation also claims that the switch in your brain to using ketones for fuel improves your mental clarity, and by hour 24 your body's immune system receives a 'complete reboot', clearing out old immune cells and introducing newer, more effective replacements.
Of course, there are a number of downsides and negative side effects that come alongside prolonged fasting periods, especially if you don't prepare properly, but it's surprisingly how much more effective your body can become under the right conditions if you give it more of a break than usual.
That's why fasting-based diets that contract the hours that you eat within during the day – such as internmittent fasting, which fixes the eating period to just eight hours across a day – are so popular and effective for some people, but others take this even further.
