After that timespan, 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.
To start, recognize that the bulk of your weight-loss is going to come from fasting, not from working out. Exercise will have other benefits, of course, like building and preserving muscle tissue, improving performance, and increasing endurance, but it won’t be where you’re really taking off the pounds. With this in mind, if your priority is to lose weight, you’ll need to be prioritizing meal planning over working out. As you start intermittent fasting, you may need to pull back from regular strenuous exercise, at least until you feel like your body is used to your new schedule.
When the female body senses it’s headed towards famine, it will increase the production of the hunger hormones, ghrelin and leptin, which signal the body that you’re hungry and need to eat (2). Additionally, if there’s not enough food for you to survive, your body is going to shut down the system that would allow you to create another human. This is the body’s natural way of protecting a potential pregnancy, even if you’re not actually pregnant or trying to conceive.
Hello Maria, I can honestly say I look forward to my morning black coffee now, just as much as I enjoy a cup with a little cream, once my eating window opens late afternoon. My easiest “go-to” tip is adding just the smallest pinch of pink Himalayan salt to my coffee. It really works to smooth out the black coffee bitterness! Good luck with your IF journey, Maria!
If you're worried you’ll be starving while fasting, you’ll be pleasantly surprised! Intermittent fasting decreases your hunger hormone ghrelin, which in turn can increase dopamine levels in the brain. (Just another example of the gut-brain axis at work.) Fasting can also help free people from emotional eating and kill cravings by transitioning your metabolism from unstable sugar-burning to steady fat-burning.
Forms of intermittent fasting exist in religious practices in various groups across the world. Religious fasting regimens include, but are not limited to, Vrata in Hinduism, Ramadan fasting (Islam), Yom Kippur fasting (Judaism), Orthodox Christian fasting, Fast Sunday (The Church of Jesus Christ of Latter-day Saints), and Buddhist fasting. Certain religious fasting practices, like Buddhist fasting, only require abstinence from certain foods, while others, like the Jewish fast on Yom Kippur, last for a short period of time and would cause negligible effects on the body.
