“Eating an LCHF diet has reversed my diabetes and changed my life”

Gisele SS

Gisele was on a high dose of insulin medication but still couldn’t keep her blood sugar levels under control. She found a video of Dr. Jason Fung someone had posted on Facebook where he talked about how to reverse type 2 diabetes naturally. Giesele thought what he was saying made so much sense. She decided to try the keto diet. This is what happened:

My name is Gisele Hansen and I started the ketogenic diet on August 3rd, 2017 and will eat this way for the rest of my life.

Starch structureI have type 2 diabetes and was on five injections a day. I took Novorapid insulin with every meal based on how many carb exchanges I ate (seven units of insulin per carb exchange). One carb exchange (15 g of carbs) is one slice of bread, half a cup of rice, one third of a cup of pasta, a three-oz potato, one quarter cup of corn, a small fruit). These are known as high glycemic carbs. I typically took 15 units of insulin at breakfast and lunch and 21 to 28 units at suppertime. At bedtime, I was taking 60 units of Lantus (a long-acting insulin) and also an injection of Victoza (a hypoglycemic). Even with all this insulin, my blood sugars kept climbing.

In late July, I watched the following YouTube video by Dr. Jason Fung that someone had posted on Facebook:

I also read his first book: titled The Obesity Code. It made so much sense. I also watched many of his other videos which led me to the one with Dr. Andreas Eenfeldt and the Diet Doctor website. I have visited the site numerous times for recipes and advice.

Dr. Jason Fung completed medical school and internal medicine at the University of Toronto before finishing his nephrology fellowship at the University of California, Los Angeles at Cedars Sinai hospital. He now has a practice in Scarborough, Ontario, Canada where he uses his intensive Dietary Management Program to help all sorts of patients, but especially those suffering from the two big epidemics of modern times: obesity and type 2 diabetes.

He says that patients who are on medication should be followed by an MD before starting this, but there was no one in my city who advocated this program, so being a nurse, I decided to follow the course myself. I was lucky to also have a daughter who is an OB-GYN, who had heard of Dr. Fung and was part of a Facebook group of physicians who were following Dr. Fung. She was my sounding-board and advisor.

The first two weeks in August 2017, I eliminated all the high glycemic carbs from my diet. No bread, potatoes, rice, pasta, corn and no foods with wheat or corn flour, or any sugar derivatives such as glucose, fructose, dextrose, etc. I checked my blood sugars 4-5 times a day and two weeks later, I no longer craved these foods. This meant I could also eliminate the Novorapid insulin that I took with every meal.

I ate no processed foods and instead, my diet switched to whole foods. I significantly increased animal and dairy fats, and the use of salt. I ate meat which included the fat, chicken with the skin, fish, cheese and all vegetables that grow above ground. I grilled my food in butter (very tasty) and made sauces with whipping cream, full-fat sour cream, etc. I also ate only low carb fruits such as berries and melons but not more than two or three times a week. I did not count calories. My only criteria was my blood sugar levels, which I checked several times a day. I ate until I was full, but only from the allowed foods. High-fat foods make you feel satisfied for many hours.

Starch structureI found it easy to adjust to this way of eating because the food tastes so good, due to the added fat. The Diet Doctor site has many wonderful recipes. I also incorporated intermittent fasting. I eat lunch and dinner, then fast till lunch the next day. No snacking. Dr. Fung says the only healthy snack is “don’t snack”. I also do two 24-hour fasts each week and occasionally did some longer fasts: 42, 48, and 72 hours. I fast when it works. I did a 7-day fast to get off the last of my insulin, my long-acting insulin. I have been injection-free since October 25th, 2017 and my HbA1c blood-sugar level (covers a three-month blood-sugar average) showed that my blood sugars are normal. I am now also off my cholesterol and high BP medications. High-fat foods do not cause high cholesterol, provided they are natural fats like animal and dairy fats, butter and olive oil. My cholesterol went down significantly within three months of eating this way. My blood pressure is now stable at 110/70.

During fasting periods, I drink tea, water, sparkling water with lemon and bone broth with lots of added salt (coffee is also allowed, but I’ve never been a coffee drinker).

My only exercise was walking to and from work, which I’ve been doing for the past six years. Exercise is very good for you but has a small role in losing weight.

I lost 75 lbs (34 kg) in eight months and have been maintaining my weight since April 2018. I now have lots of energy and am in better shape so able to play with my grand-children and go for long walks.

This ketogenic diet has truly changed my life. I wish I had known about this regime twenty years ago when I had followed a similar way of eating, but without the intermittent fasting, my weight plateaued and I gave up.

I used to hate shopping, but now wear a size 12 instead of a size 24 and I love it. I no longer feel uncomfortable in social situations or when meeting new people. I remember going to job interviews and getting that feeling of rejection, the minute I walked in.

The Diet Doctor site has been a wonderful support, and I love receiving their newsletters and reading all the testimonials.


Congratulations, Gisele! As someone with type 2 diabetes, to be able to get off more than 100 daily units of insulin, plus more medications, and still manage to normalize your blood sugar is quite impressive.

Obviously, when it comes to changes in medication, we always recommend doing this under the supervision of a health care professional (full disclaimer). But the sad reality is that most doctors are not used to de-prescribing diabetes medications… they are mostly used to increasing the dose. So it can still be a challenge to get needed support for this. I’m happy to hear how well it has worked out for you.

    My body stores fat and makes Hugh fatty tumors. ???

    Cardiovascular disease is the killer of most diabetics. This diet may help reduce secondary diabetes health issues like blindness, kidney failure, amputations, etc.. But, I would be very worried this diet will supercharge the diabetic killer, cardiovascular disease.

    Well you would be wrong because actually it's carbs n sugar that drive heart disease. Ive managed to distill years of research down to one sound bite that I repeat ad nauseum to my family and anyone who will listen...." Drive fasting insulin down, down, down through a Ketogenic diet and IF. Drive Vitamin D up, up, up and eat more fat." I was thrilled to have it repeated to me by my daughter when I complained of sore knees......and I was able to say to her "well you've learnt something then."

    John, I know conventional wisdom says a high fat diet causes heart disease but conventional wisdom is wrong. Eating fat is completely natural for our species. Eating lots of sugar and carbs is not. Ive been eating this way for 2 1/2 years, eliminated diabetes, high blood pressure and a host of other medical issues as well as losing 50 lbs. Im not the least bit concerned about heart disease.

    Its being proven more and more each day that the cholesterol theory was based on completely flaw research and we have been lied to for 40 years because of big pharma...When you look at actual studies on statins they reduce 1 cardiac event out of 100 people over 5 years...not a very good return
  6. Martin
    That John did not get it until now is quite clear. But this is Giseles story!
    Gisele is just doing so right and it is so nice to hear again a story like hers..
    Andreas again is right as doctors are still going against our opinions and findings.
    But it will improve: even my doctor admitted, that fat is not the culprit and stopped now
    immediate blood pressure testing when I enter his premises as I am on 105 /60 ever since
    I changed to "as much ketogenic as possible". And on 28.12. it will be 5 years into this way
    of living. Gisele: please carry on : fingers crossed.
  7. Carol
    You are right! Amazing effort Gisele. Thanks for sharing to inspire and save the lives of others.
  8. Tera
    Congratulations on getting your life back - and putting it back on the right track!

    Gisele, what a wonderful story and bravo for taking back your health! Truly inspiring and I wish you many years of comfortable, happy Keto and continued awesome blood sugar control. BRAVO!

    Keep doing your research John. Excess insulin causes cardiovascular disease, not fat. I never got over 75kg but my blood pressure was 180/95. I carefully ate what I was told to and dosed up on insulin to deal with the carbs. Ive been doing HFLC for one year now and my Hba1c is down to 5.7 and my blood pressure is down to 120/80.



    Disease of coronary, cerebral, and peripheral arteries is associated with exaggerated insulin responses to oral glucose. In three populations, high fasting or post-glucose insulin levels have a predictive value in the incidence of ischemic heart disease and in cardiac mortality. Diabetics who are obese or who have received treatment with insulin have elevated insulin levels and, as a group, have an increased incidence of cardiovascular disease. Insulin, in small concentrations, has effects on arterial tissue including stimulation of smooth muscle cell proliferation and of glucose incorporation into lipid. It is suggested that insulin has a role in the development of atherosclerosis.
