Is Intermittent Fasting Bad for
Type 2 Diabetes?

Consider intermittent fasting as a simple weight-loss option if you want to improve your health. It also reduces the likelihood of diabetes complications. However is intermittent fasting bad for type 2 diabetes?

Although some people with diabetes run the risk of both hyperglycemia and hypoglycemia, intermittent fasting is a safe way to lose weight. Because it alternates between periods of eating and not eating, as opposed to skipping all of your meals at once, intermittent fasting gradually alters blood sugar levels.

Insulin could be replaced by intermittent fasting for type 2 diabetics. The difference between a type 1 and a type 2 diabetic is that a type 1 diabetic lacks insulin.

The most numerous insulin-producing islet cells in the pancreas, known as beta cells, are unable to continue producing insulin, so there is nothing to maintain low blood sugar levels. As a result, a type 1 diabetic has extremely high blood sugar levels and needs to administer insulin.

What Is Insulin Resistance?

A resistance to the hormone insulin results in increased blood sugar.

Controlling blood sugar (glucose) levels is aided by the hormone insulin. Cells in the body don’t react to insulin as they should when there is insulin resistance. As a result of glucose’s difficulty entering cells, it accumulates in the blood. This can eventually lead to type 2 diabetes.

Insulin resistance, a complication of type 2 diabetes, causes the body to initially produce an excessive amount of insulin, but this insulin is ineffective because the cell’s receptors are unable to take it up into the body.

As a result, there is a situation where there is a lot of insulin in the body but it is actually not producing any significant effect, which causes the blood sugar levels to rise. (3)

Daily intermittent fasting to reverse insulin resistance can result in stopping insulin to control blood sugars. It is so effective at helping control blood sugar that it eliminates the need for insulin for many who do regular fasting.

So, is fasting safe for diabetics? This article will discuss the benefits and hazards of intermittent fasting for patients with type 2 diabetes.

What Does Intermittent Fasting Entail?

Benefits Of Intermittent Fasting For People With Type 2 Diabetes

Weight Loss

Most people with type 2 diabetes ask if fasting is safe for diabetics. Intermittent fasting aids in the loss of fat and calories. Over time, it also burns the extra fat in the pancreas and liver. Weight loss lowers hemoglobin A1C, which monitors blood sugar levels. People who practice intermittent fasting on a regular basis lower their cholesterol levels, lowering their risk of a heart attack or stroke.

Insulin sensitivity

Intermittent fasting decreases visceral fat, which increases insulin sensitivity in obese or healthy people; it also helps to minimize glycemic variability, or the rapid swings in blood sugar levels throughout the day.

Metabolic switching

The body processes the necessary amount of carbohydrates from our diet into energy. However, glycogen is still present in the liver and skeletal muscles.

Furthermore, excess fat generated from energy is retained as triglycerides as a tissue or body fat deposit. The body is in a ketogenic state during this procedure. Insulin production is slowed as blood sugar levels rise less rapidly. As a result, it has an impact on the liver and pancreas.

Health Autophagy

This occurs when old, injured, or dead tissues and cells are replaced regularly with new cells. Autophagy is improved by intermittent fasting. It aids in the reduction of inflammation and the risk of cancer.
