Intermittent Fasting While Sick - Is It A Good Idea?

Catch a cold and caught wondering if you should skip your Intermittent Fasting protocol for the day? Think about this: if you've ever had a pet that gets sick, it tends to quickly lose it's appetite and interest in food. There has to be a reason for this right? It turns out the human (and animal!) body is pretty clever by reducing the urge to eat when you don't feel well.

Today I'm sharing 4 reasons you may want to consider continuing your Intermittent Fasting protocol while battling your cold/flu.

1. Increased Beta-Hydroxybutyrate Production

That's certainly a mouthful! While following Intermittent Fasting, your body begins using fat as fuel. One major benefit of this process is the increased production of ketones in your body. One ketone called beta-hydroxybutyrate has even been found to reduce the inflammatory response.

2. Faster Turnover of Immune Cells

Your immune system, like every part of your body, requires a process of regeneration. This regeneration can help to boost your immune system by removing damaged immune cells and replacing them with healthy ones.

3. Discarding Sick Cells

Remember that thing called autophagy? Autophagy is the process of removing waste products and damaged organelles from your cell. When you're sick, this process can help make your mitochondria more efficient at producing the energy needed to fight the infection.

4. Turns on Power Saving Mode

You know when you're at 20% battery and your phone switches over to power saving mode? This process is meant to save energy for only the most crucial apps (like YouTube so that you can go and watch my videos... right?!). Breaking down food in your GI tract requires a ton of energy. Considering we all have fat stores that we can tap into, using energy to break down food while you're also fighting an infection isn't the best utilization of fuel.

Make Sure You're Also Doing This

If you choose to take advantage of Intermittent Fasting while you're sick, it's also important to keep a few key aspects in mind: hydration, minerals and natural remedies. When you're sick, you become more easily dehydrated, so sipping on extra water throughout the day (especially during your fast) is crucial.

With hydration in mind, you know that you also need to be balancing your electrolytes with minerals too. Add a pinch of Celtic Sea Salt to your morning water to get those minerals in.

Lastly, nature has given us a plethora of natural remedies to fight infections. Garlic is a natural antibiotic, anti fungal and antiviral that also doesn't risk antibiotic resistance (the way regular antibiotics do). Take advantage of garlic and other natural remedies HERE.
