How long should a diabetic fast?

Diabetes, the silent killer! Well not so silent anymore. In a world where everything seems to revolve around food, it’s important for people with diabetes to consider fasting as an option in their daily routine. But how long should they fast? Is there an ideal duration that provides maximum benefit while minimizing harm? Let’s explore this question together.

Understanding Diabetes

First things first – let’s talk about diabetes. It is characterized by high levels of sugar (glucose) in the blood which can cause damage to various organs and systems in the body over time. There are two types of diabetes – Type 1 and Type 2 each with different causes but both resulting in elevated blood sugar levels.

Type 1 diabetes is caused by a malfunctioning immune system that attacks and destroys cells in the pancreas responsible for producing insulin, a hormone that helps regulate glucose levels in the blood.

Type 2 diabetes on the other hand is primarily caused by lifestyle factors such as unhealthy eating habits, sedentary behavior, obesity etc., leading to decreased sensitivity of cells to insulin hormone or reduced production of insulin from pancreas cells.

In both cases though, controlling blood sugar levels through proper diet and exercise regimes becomes critical; hence DIETARY FASTING comes into play.

Types of Fasting

Before we dive deeper into answering our essential question,“How long should diabetic patients fast?” lets take some time learning more about dietary fasting itself.There are several variations when it comes to Dietary Fasts they include:

Intermittent Fast

ProLon Fasting

Next up comes ProLon fasting,which is time restricted and usually performed under the guidance of experts. This involves consuming predetermined meals for about five consecutive days(meals being specially designed ) followed by going back to normal eating.Schedule varies from person to person depending on underlying conditions.

Alternate Day Fasting (ADF)

A more intensive form of Dietary Fasts includes Alternate-Day-Fast which as the name suggests, requires you alternate between regular meal consumption one day and having very few calories or skipping meals altogether on the next.Setting realistic goals,such as only doing it once a week if at all helps you cope better .

Extended Fast

Although effective , this fasts may increase certain risks especially if its not done properly.Included here are prolonged fasts/exclusion diets.Discussing with your doctors before performing such an act could provide further insights in terms of dos and don’ts.
