It's well knowing that when you eat your body begins a series of biological processes to digest and use the nutrients found in that food to help you repair muscle create new cells and store some of the extra fuel as fat for later use but it's not common knowledge, that when you don't eat your body enters a completely Different Series Of Biological Processes That Are Just As Necessary And Beneficial As The Processes That Occur After Eating.
Of course if you don't eat for long enough the negative effects will start to outweigh the positive effects but there are definitely myths and misconceptions about exactly what happens to your body, when you stop eating so today k want to go over that processes step by step based on the scientific evidence and first let's address the conventional advice which would tell you that it's unhealthy to go for long periods of time without food and i dont mean days or weeks i am talking about simply skipping meals on the contrary.
We have been told that we should eat small but frequent meals the truth however is that there is nothing natural about eating five or six meals spread out evenly the hours that you are awake every day this is because throughout our evaluation we didn't always have access to food, so you could claim that a fasting and feasting eating cycle is actually more natural than eating breakfast lunch and dinner every single day due to the fact that our ancestors had to cope with cycles if food shortage and food abundance we have developed metabolic pathways that help us cope with prolonged periods without food.
In fact fasting for certain periods can actually benefit your health rather than hurt it but it definitely doesn't feel that way because one of the first things that will happen when you stop eating is you will start to feel unpleasant feeling of hunger, now the intensity of this feeling of hunger highly depends on how accustomed your body is to burning fat for fuel you see most people regularly eat a high carb diet so their body relies primarily on glucose for energy instead of using fatty acids or ketone bodies your body has the ability to store a lot of fatty acids in the form of body fat.
And those fatty acids can be used for energy at a later time when food is scarce by converting the fatty acids into kentone bodies in the liver but with glucose it's an entirely different story your body can only store a very limited amount of glucose in your muscles and liver for future use and this amount gets depleted after fasting for only 24 hour but depending on how many carbs you eat regularly it can take as little as 8 hours or up to 48 hours after that point your body will have to rely on a different energy source in the form of fat and if your body isn't effective at burning fat for fuel this will likely lead to cravings.
Especially for high carb food now if you have trained your body to use fat for fuel by let's say following a low carb diet a keto diet or you have gone through long duration fasting in the past then you will not experience the same severity of hunger cravings in fact many people that fast frequently dont experience hunger at all this isn't only because their body is used to burning fat for fuel but it's also because hunger levels increase at the time of the day that you normally eat this is due to the hunger hormone ghrelin which has the effect of stimulating your appetite.
When it's released so during those first 24 hours that someone will stop eating studies show that ghrelin will spike automatically for most people around the times of the day that they typically, have breakfast lunch and dinner and that spike will make you feel hungry however if you're someone that is already become accustomed to fasting every single day you will not experience these sharp spike and ghrelin during your fasting window meaning you will not feel as hungry as someone that is used to more meals throughout the day.
But even if you are used to breakfast lunch and dinner you should know that the date shows us that the spike in ghrelin is short lived if you just Ride Out That Hungry Feeling That You Get Within About Two Hours From The Initial Spike In Ghrelin It Should Drop Back Down To Normal Levels And Your Appetite Will drop down as well regardless after about the first 24 hours your body will burn through your remaining glycogen stores and switch almost entirely over to burning fat for fuel which will slowly lead to weight loss.
