What about people with diabetes?

It has been a popular topic among our diabetes smarts community too.

So today we will discuss it.

In this article, we’ve got the low-down on everything you should know when it comes to intermittent fasting and diabetes.

 Keep reading as we reveal

  • What exactly intermittent fasting involves.
  • Why so many folks are turning to it for weight loss
  • Is there a right way or wrong way to do it?  
  • What you want to avoid when it comes to fasting.

And of course – THE BIG QUESTION… 

Is INTERMITTENT FASTING Safe For People Living With Diabetes?

 So let’s dive into it…

First of all… What is Intermittent Fasting?

Technically, intermittent fasting - also known simply as ‘I.F.’ - is an eating pattern where one cycles between periods of fasting and periods of eating.

It’s unlike a typical ‘diet’ since there are no restrictions on the TYPE of food you can eat.

Although if you’re diabetic… you’re going to likely WANT to be careful as always as to what you eat.

Some common types of intermittent fasting involve 2-24 fasts a week... or 16-hour fasts each day with an 8-hour eating window.

 This 24-hour fasting method is known as the ‘EAT-STOP-EAT’ method.

 In this method, you wouldn’t eat ANYTHING from dinner one day to your following dinner the next day.

AND it’s not for everyone! As you know I am not diabetic

I did try this pretty extreme fasting for a few days after a buddy roped me in to give it a go with him.

Truth be told it was torture. And I was miserable. I need my breakfast!

In hindsight, I should have tried the shorter method (we’ll get to in a sec) first…

There is the popular 16-8 method (not so extreme)

Usually, this involves fasting for 16 hours, including as you sleep (which makes it MUCH easier to follow).

Then, say between 10 am to 6 pm or 1 pm and 9 pm, If you’re a night owl you can eat.

There’s also another third fasting category. This is often referred to as the 5:2 diet.

The 5:2 diet involves consuming only 500-600 calories for 2 days a week. These 2 days are NEVER back to back. For example, you could do Sunday and then Thursday, but not Sunday and Monday.

Then… you eat normally the other 5 days of the week.

So, what happens to your body when you fast?

When you fast, the body usually runs out of glucose. When you eat, your body relies on glucose from these foods to create energy.

In the absence of glucose… the body begins using ketone bodies for fuel which requires the breaking down of stored fat.

Studies have shown that this can lead to:

  • decreased inflammation
  • improved glucose regulation
  • And better stress adaptation.

 In fact… It has also been shown... that intermittent fasting can improve insulin sensitivity... which can help balance blood sugar - something that is SO important for those with diabetes.

 Intermittent fasting can also help you lose weight, That is why most people try it out.

 (And of course, losing weight has been shown time and time again to help manage - and even reverse - type 2 diabetes)  More about this in a bit)

 So to answer the big question: Is it safe for diabetics?

 The short answer is it can be as long as safety guidelines are followed.

 Dr. Deborah Wexler, Director of the Massachusetts General Hospital Diabetes Center and associate professor at Harvard Medical School stated in an interview…

“There is evidence to suggest that the circadian rhythm fasting approach, where meals are restricted to an eight to 10-hour period of the daytime, is effective,” she confirmed, though generally, she recommends that people “use an eating approach that works for them and is sustainable to them.”

So if you are looking at intermittent fasting as a way to reverse or manage your diabetes.

There are a few things you need to keep in mind.

The first is a MUST

Before beginning ANY fasting regime, seek out the advice of your doctor.

Like most things. There is always SOME risk.

Intermittent fasting is no different.

For instance…

If you take insulin or other medications to help manage your diabetes.  And you dive headfirst into eating MUCH less than normal… your blood glucose levels might drop TOO low.

This is known as ‘hypoglycemia.’ Which comes with a host of symptoms – The most common being shakiness, a rapid heartbeat, chills, drowsiness and nausea.

Then… there’s the DANGER of experiencing ‘hyperglycemia.’ This is when your blood sugar climbs TOO HIGH.

And this can happen when you eat a lot more in a small amount of time… such as during an 8-hour eating window in the 16-8 I.F. method.

And I am sure you’re aware of what high blood sugar can lead to if you’re diabetic…

SO… there are some risks.

This is WHY it’s SO important to talk with your doctor before beginning any new fasting method

Your doctor knows you and your health situation the best and can offer guidance on how to SAFELY go about it.

They can also supervise and give you support when you first begin. And provide ways for you to measure and determine how it’s going.

You’ll want to monitor your blood sugar levels, your mood, and energy levels throughout the day.

If you have diabetes... you’re probably already familiar with monitoring your blood sugar levels.

In fact… Many individuals with diabetes use a continuous glucose monitor to ensure their blood sugar levels remain stable.

This monitoring can help you make better decisions when it comes to eating times... and what you should be eating.

And this monitoring is ULTRA important when you’re trying out a new eating pattern… like intermittent fasting.

It can help you determine how your body is adjusting. And help you steer clear of any dangers like low or high blood sugar.

And a word of WARNING here: If your blood sugar drops below 70, end your fast immediately.

Grab something to eat. REMEMBER you don’t need to go ‘ALL IN’ at the start, nor should you.  The body needs time to adjust.

This monitoring is especially important when you’re fasting as well as when you first start your eating window.

A few other things you might want to track include your MOOD and your ENERGY levels.

Life is MEANT to be enjoyed right?

And if you’re fasting is making you feel bad and sucking all your energy..

Then maybe it’s not worth it. Maybe it isn’t right for you. And that’s okay!

So there you have it – A quick rundown of how Intermittent Fasting works with diabetes and what you should do if you try it out.
