Ketogenic Diet and Insulin Resistance

Ketogenic Diet and Insulin Resistance

Ketogenic diets around the world have been known to be extremely effective in helping improve health and lose weight fast.

The diet takes into account and addresses the underlying causes of your weight gain, which could include things such as hormonal imbalances.

With the ketogenic diet, you are restricting your net carb intake to under 50 grams a day.

With the number of restricted carbs, your body needs to reset its way of getting the fuel that it needs.

See how a diet high in healthy fats can help improve insulin resistance by changing the bodies preferred fuel source from glucose to ketones.

What is Insulin and Insulin Resistance

Insulin is a fat storing hormone formed by the pancreas that enables your body to manage glucose and sugars from carbs within the food.

It prevents blood sugar levels from hyperglycemia or reaching too high or hyperglycemia which is too low.

Insulin resistance has many symptoms including sugar cravings, weight gain, high blood pressure, high cholesterol.(1)

Insulin resistance is also linked to type 2 diabetes. Therefore, cutting out or reducing sugar in your meal planning will help prevent becoming diabetic.

The worrying thing about insulin resistance is symptoms take a long time to appear. When symptoms surface such as weight gain, multiple other problems may creep up.

How does a ketogenic diet improve insulin resistance?

Why You Gain Weight

Insulin in your body helps to regulate your blood sugar levels. Blood sugar also referred to as glucose is the primary fuel in the body for energy and brain function.

When blood sugar rises, the insulin your pancreas releases move the glucose into your bloodstream. If there is glucose in your system your body will burn it first for fuel.

If your body is already filled with higher glucose levels, more cannot be broken down for fuel.

So because of this, your body stores these excess levels as fat.

Having high levels of insulin can lead to developing type 2 diabetes. Some quick diabetes facts are it affects 25.8 million people or 8.3% of the U.S. population with 7 million people undiagnosed.(2)(3)

What Makes Insulin Levels Rise?

The short answer to this question is higher levels of carbohydrate consumption.

Carbohydrates are used by the body and broken down in your gut. This then turns them into blood sugar.

Since complex or simple carb both convert into blood sugar it doesn’t really matter the type you eat.

When you consume excess sugar with your meals, your body releases more insulin.

So essentially if you eat high levels of carbs, the body must release a ton of insulin to compensate for this.

Modifying your nutrition and eating healthy high fat diet can help fix the problem by limiting the number of sugars you consume.

With the ketogenic diet plan, you limit your carb consumption to help decrease the amount of insulin your body needs.

With a lack of carbohydrates for energy, your body will start to burn the stored fat levels, helping you to lose weight in the process.

Ketogenic Diet Plan

When starting a ketogenic diet nutrition plan, you will want to start by limiting the number of net carbs you eat to under 50 grams a day.

In doing this, it’s a good idea to choose healthier carbs over the starchier and sugar-filled carbs. Vegetables and fruits are great choices.

Green leafy and bitter low-glycemic vegetables are healthful, wholesome sources of carbs.

In addition to the carb reduction, you may want to decrease the amount of protein you consume as well. It will depend on how well you can adjust to a high-fat diet.

Many people often increase protein intake and end up making it more of an Atkins or typical low carb diet. Eating fatty foods helps combat this issue.

Eating darker meats that contain more fish oil is a great beginning part. These include salmon, lean beef, and lamb.

Once you’ve made a few lifestyle choices and changes you will be amazed just how fast the pounds start to fall off with a ketogenic diet weight loss plan.

How to know if you have insulin resistance?

See you’re GP or health-care professional and they can take blood tests, a detailed history, and performing a physical examination to see if you have insulin resistance.

Fasting blood glucose and insulin levels are normally enough to establish whether you are pre-diabetic, have diabetes or insulin resistance.

If you find out you have symptoms then you can manage it primarily with more exercise, better nutrition and other lifestyle changes.

The more carbs you eat, the more it will release insulin. Restricting net carbs to 20g-50g by essentially eating fatty foods will help improve insulin levels.

It will also help raise good cholesterol and reduce the risk of heart disease by stabilizing blood sugar whereas a high carb diet will increase risk.(6)

Studies show a ketogenic diet can assist with raising good cholesterol (HDL-C) and aid weight loss.

Comparing keto to a low-fat weight loss diet, a very low-carbohydrate diet did not lower LDL-C but prevents the decline in HDL-C. It also results in improved insulin sensitivity in overweight and obese people.(7)

Anyone can benefit from lowering sugar intake and increasing healthy foods. If you have symptoms of insulin resistance or concerned about your blood sugar, don’t delay and make an appointment with your doctor.
