Imagine it like someone yelling in your ears over and over again until, finally, you plug your fingers in your ears, and you can’t hear the yelling so much anymore. On a high-sugar diet, cells eventually become overwhelmed with insulin “yelling,” and they become resistant and unable to respond properly.
As you say goodbye to that excess sugar and welcome in the healthy fats, you’re also reducing the need for insulin. A degree of carbohydrate restriction is often recommended for people with diabetes or prediabetes because carbohydrates turn to sugar in the body, and too many carbs can lead to high blood sugar spikes and subsequent crashes.
Research reveals keto improves blood sugar, blood pressure, and glycemic control, and results in medication reduction and discontinued insulin requirements.  A lower glycemic diet is correlated with lower blood pressure, which could be partly due to the reduction of insulin.
A recent study concluded that carbohydrate reduction normalized blood sugar in over 50% of people with prediabetes. The study involved fewer than 30 grams of total carbs daily, dietary fat to satiety, and 1.5 grams per kilo of protein. On average, participants lost weight and experienced drastic improvements in their triglycerides, HDL cholesterol, liver function, and fasting insulin levels. 
Another study compared a low-carb ketogenic diet with a low-calorie diet for obese type 2 diabetics, and researchers discovered the low-carb keto diet was far superior to the low-calorie diet in improving glycemia. 
Why Keto Is a Good Choice for Prediabetics
A ketogenic diet isn’t just a diet or a fad; it’s a metabolic shift from being a sugar burner to a fat burner. Keto eases the sugar and insulin burden on your body, giving you a chance to normalize your metabolism.
A ketogenic diet has been proven anecdotally and in scientific literature to help manage prediabetes and diabetes. Keto can improve many of the risk factors for developing diabetes, including:
- Excess body fat (abdominal fat)
- High blood pressure
- Unstable blood sugar
- Metabolic syndrome
- Low HDL cholesterol
- Poor sleep
Most docs suggest eating a well-formulated ketogenic diet with healthy fats, good-quality protein, and a range of low-carb foods like veggies. Stay hydrated, get sufficient exercise, and snack when you need to.
