Understanding how intermittent fasting leads to fat loss we first need to understand the difference between the fed state and the fasted state.
Your body is in the fed state when it is digesting and absorbing food. Typically, the fed state starts when you begin eating and lasts for three to five hours as your body digests and absorbs the food you just ate. When you are in the fed state, it’s very hard for your body to burn fat because your insulin levels are high. (Its burning all that shit you just ate and not the fat hanging onto your body)
After that time span, your body goes into what is known as the post–absorptive state, which is just a fancy way of saying that your body isn’t processing a meal. The post–absorptive state lasts until 8 to 12 hours after your last meal, which is when you enter the fasted state. It is much easier for you body to burn fat in the fasted state because your insulin levels are low. (You now burn that fat hanging onto your body)
When you’re in the fasted state your body can burn fat that has been inaccessible during the fed state.
Because we don’t enter the fasted state until 12 hours after our last meal, it’s rare that our bodies are in this fat burning state. This is one of the reasons why many people who start intermittent fasting will lose fat without changing what they eat, how much they eat, or how often they exercise. Fasting puts your body in a fat burning state that you rarely make it to during a normal eating schedule.
Personally, My eating window is 12:00pm-8:00pm, So I'm skipping breakfast and I go without eating for 16 Hours. I Train in the mornings a few hours before I break my fast.
People ask me why I don't just eat 5-6 small meals a day, I've tried that and although it does work to a degree it's hard as hell for me to drop under 9% body fat eating like that. Some people say it doesn't matter but for me it does. This Method seems to work for me so this is my take on it, all of this is just advice.
Have a kickass day,
