Effect of keto diet on diabetes

The keto diet has the potential to reduce blood sugar levels. Because in ketogenic diet one eats a very low or no carbohydrate, and people with diabetes are recommended to take low carbohydrate and this is because carbohydrate turns into glucose and this for people with type 2 diabetes. So instead of burning glucose it will burn fat.


How ketogenic diet works

All the cells in our body needs fuel to function. This fuel comes from fat, carbohydrates or protein. Too much protein without fat puts our body into risk, so protein can never serve as a primary source of fuel. So now how about fat and carb. Normally our body preferred carbohydrate to carry out everyday task. This carbohydrates is now converted to glucose,which is readily converted to energy. This is why athletes “carb load” before they compete. Peak performance occurs when the body has plenty of glucose and glycogen stores available at hand. When glycogen runs out, that’s when the body turns to fat. When there is no more blood sugar for our cells to consume, they seek an alternative form of energy. This energy comes from ketones, which are compounds our body produces from stored fat. So a ketogenic diet is one that is high in fat and very low in carbohydrates, resulting in the production of ketones to be used for fuel instead of glucose. A diabetic person stays away from food with high carb content which is also what someone on a ketogenic diet does.

Impact on blood sugar levels

A ketogenic diet may help some people with type 2 diabetes because it allows the body to maintain glucose levels at a low but healthy level.

The lower intake of carbohydrates in the diet can help to eliminate large spikes in blood sugar, reducing the need for insulin.

Studies on ketogenic diets, including research from 2018, have found that they can be helpful in controlling levels of HbA1c. This refers to the amount of glucose traveling with hemoglobin in the blood over about 3 months.

Keto Diet For Diabetics

(Keto Diet For Diabetics) Diabetes Control Food

A ketogenic diet should consist of the following types of food:

  • Low-carb vegetables: A good rule of thumb is to eat non-stavegetables at every meal. Beware of starchy vegetables, such as potatoes and corn.
  • Eggs: Eggs are low in carbohydrates, as well as being an excellent source of protein.
  • Meats: Fatty meats are acceptable, but should be eaten in moderation to be mindful of heart health. Also, be mindful of consuming too much protein. Combining a high level of protein with low levels of carbohydrates may cause the liver to convert the protein into glucose. This would raise blood sugar levels.
  • Healthful fat sources: These include avocados, olive oil, nuts, and seeds. Although the diet is mostly fat, it is important and recommended including mostly healthy fats over not as healthy options such as bacon, sausage, red meat, and fried cheeses.
  • Fish: This is a good source of protein.
  • Berries: These are good sources of fiber, vitamins, minerals, and antioxidants that are okay to consume on the keto diet in the right quantity.

Is Keto Safe if You Have Diabetes?

That depends on the type of diabetes you have. In general, people with type 2 who are overweight seem to get good results safely. If you have type 1 and want to try the keto diet, it’s essential that you talk to your doctor first. You’ll need to carefully monitor your health and watch for signs of ketoacidosis. For either type, it’s a good idea to work closely with your doctor, since you may need to change your medications. The keto diet has some side effects that are worth knowing about, too:Hypoglycemia: Though the diet can lower A1c levels, that may mean you’re at a higher risk of blood sugar that dips too low, especially if you’re also taking medicine for your diabetes. Let your doctor or diabetes educator know if you try the keto diet. They can advise you about checking your blood sugar, taking your medicines, and what to do when your blood sugar drops too low.


There is generally a lack of long-term studies into the safety and effectiveness of ketogenic diets and, this is why a doctor’s opinion is needed before starting the diet.

There are a few groups of people for whom a ketogenic diet may not be suitable, or at the very least, warrants close supervision.

These include pregnant women, children, people at risk of hypoglycemia, people with a very low BMI, and those with conditions that a ketogenic diet may exacerbate.

To succeed on a keto diet when you have diabetes you should

  • Determine an effective treatment plan with your doctor.
  • Implement a ketogenic diet that limits dairy and wheat consumption.
  • Check blood sugar levels frequently throughout the day (at least 8-10 times).
  • Supplement with vitamin D3 by getting sun exposure and taking a supplement every day.
  • Exercise daily, but make sure you monitor your blood sugar and check for hypoglycemia symptoms.
  • Get your A1C levels tested every three months to determine the effectiveness of your treatment plan.




  1. The keto diet is so popular today and I know, it truly does work! I know at least 3 people who have lost over 80 pounds in less than one year on this “diet”. I would call it more of a ”way of life”. Not only did they lose weight but their health improved considerably…including their diabetes. What you say in this article is so true! Keto is the new way of life!

  2. Interestingly I been worried with my 17 yr old daughter who has not been eating properly in the past 2 months, when we went to the doctor few days ago, one of the tests came out indicating that she is in a ketogenic state. When I probed the doctor further as to how this is happening , he said because my daughter eats once a day, mostly in the evenings, so she is practically on a fasting mode. I got a bit worried because a few years ago she was diagnosed to be insulin resistant. Now should I worry about this ? Of course the doctor is well aware of the conditions.

    I also had issues with one of runners last year to started keto diet as a form of improving his marathon performance and lose weight. I think he surprised me because he achieved both but the problem is that he has gained more weight than he had before and has almost stopped running.

    So my question is how sustainable is keto diet for athletes as a lifestyle regime? How does one avoid regression because it would seem to me that the results are shot lived? Do we have adequate researched material on how keto is benefiting the athletes especially those who are diabetic.

    Otherwise thank you for a great article

    • Hi Sphiwe Dubandleala.
      Thank you for reading.
      Am sure the Doctor would have told you and your Daughter what to do. The Doctor was right,because if one count down on the number times they eat in a day, and especially eating less carb, they will be in ketogenic stste. It also helps with diabetes because the carb intake is less as recommended for diabetic person. And as you said she was diagnosed with Insulin resistant. I suggest you keep an eye on her. But if it was a source of concern am sure the Doctor will tell you.
      Personally I do keto diet and that has been the diet that has worked for me and keep the weight of.
      when you do keto and don’t follow it properly, even though you lose the weight at first you will add them all back. Ketogenic diet is not what you say you do today and tomorrow.I have written something on that you can check it out in one of my articles.
      As for athletes doing keto, is great because you have endly energy which helps them. But it has its pros and cons. Is all down to an individual.

    • MD Mamum thank you for reading and leaving us a comment. keto diet really have a good effect on diabetes, especially when properly done, you can explain it to your Mum a bit more, help to do proper. Thank you

  13. I’ve been wondering about the same thing whether I should get my mom to try keto diet. She’s type-2 but her craving for sugar and carbs is hard to beat. Sometimes I would catch her taking food that she’s not supposed to. Recently, I saw a meal delivery service that offers keto diet menu and thought I could get her a week’s meal plan to try. The advantage here is that she doesn’t have to cook for herself and she gets to eat healthy food at the same time, Will sign up and see how that goes. 

    • Hi Cathy, thanks for reading. If you can get your Mum to try it she will not regret it i tell you. I have seen the effect it has on Diabetic people. Maybe make a deal to try it for a month and see how it goes. Let me know how you get on, will love to know if she did stay away from sugar. There also keto approved sweeteners.
