One of the hottest diet trends that you've likely come across at some point or another is intermittent fasting. If you're looking to gain control over hunger and free yourself from constant thoughts of meal planning and everything associated with it, this might just be the diet for you.

But, before you dive into an intermittent fasting approach yourself, you might be wondering how it's going to influence your energy levels.

Is this diet going to cause you to suffer from a huge energy drain throughout the day, making it next to impossible to go about your daily activities? Or, is it an approach that you could easily make use of and sustain proper energy levels at all times?

In order to answer this question you need to consider a few points.

Energy During The Fast

First let's touch upon the time when most people are worried energy may falter – during the fast. The fact of the matter is that most people report seeing noticeably increased energy levels while fasting, giving them more mental clarity as well as physical performance.

You may wonder how this could be though. How could you have more energy not eating?

The answer to that is that when you go through a fasting period, your body is actually going to begin releasing certain endorphins that serve to stimulate the energy level and make you more active.

If you think about this from an evolutionary perspective, it makes sense. If you were starving and had no food, you would have to go out and hunt or pick that food. Both of these activities take energy. So, the body adapted to provide you with this energy so that you could get the nourishment you need.

Energy During The Eating Period

The second time that you may wonder about is the feasting period. This is where you may actually see an energy decrease for a short period of time. If you're using a higher carb intermittent fasting protocol, the sudden rush of carbs hitting your system can cause serotonin to be released in full force, which is a neurotransmitter that tends to have calming effects on the body and will make you want to sleep.

The good news is that this will pass relatively quickly and the longer you stick with the intermittent fasting protocol, the less noticeable this will be. Soon you'll find you're more energized throughout the entire day and don't have this issue.


Finally, the last thing to note is that it will take some time for your body to adapt to this way of eating. Your body doesn't especially enjoy change and prefers to stay at homeostasis. That said, any time you introduce something new, it may try and fight it for a short time.

Push through this period. If you can get through the initial two weeks using the intermittent fasting diet protocol, you'll likely find that any feelings of fatigue reside and you feel better than ever.
