Australian Personal Trainer Reveals The Hidden Dangers Of The Keto Diet

It’s like the mafia – the further you get in the harder it is to get out.

The keto diet is credited with everything from Lebron James’ abs to Kim Kardashian’s internet-breaking booty (and the body ‘transformations’ of thousands of everyday people). However, as the low-carb regime grows in popularity, more and more people have reacted badly to it.

While this is always going to happen as any large population experiments with anything, in terms of Keto specifically, Drew Harrisberg, an Australian exercise physiologist and personal trainer has a dire warning for diabetics (and a cautionary word for everyone else).

Drew recently revealed to Whimn that despite achieving a lean body type, great fitness, enhanced concentration, flatline blood sugar levels and “my lowest ever insulin requirements” on the Keto diet, he will never try it again, because it compromised his ability to process carbohydrates.

“I noticed that every time I ate foods containing carbohydrates, my blood sugar went very high, and that frustrated me. I also noticed that my cholesterol went up to 6.4 mmol/L. Sure, I was very efficient at burning fat and ketones for energy but my tolerance for foods containing carbohydrate went down noticeably, even after a workout when I’m usually my most insulin sensitive.”

Not only could Drew no longer eat a healthy snack like a banana without a large blood sugar spike, but he noticed that he needed more and more insulin, “To bring my blood sugar back down into the normal range.”

And while die-hard Keto advocates will blame carbs for these sugar spikes, Drew says that would be a case of mistaken identity: “Even if I didn’t eat anything and my own body produced glucose endogenously (i.e the liver dumped glucose into my bloodstream via a process called gluconeogenesis), I couldn’t fix my high blood sugar levels because I was resistant to the insulin I injected.”


“It felt like I was on my way to developing type 2 diabetes (type 1 is more than enough, thank you). It was a very frightening reality and a huge wake-up call.”

Why did this happen? Turning to the experts over at Medical News Today, it’s because even though Keto can help stabilise a diabetic’s blood sugar levels, it is never going to fix the root of your illness, just hide the symptoms (and in Drew’s case compromise his ability to deal with sugar even more). So every time he stepped out of the diet he was punished.

“Some people with type 2 diabetes who also follow a ketogenic diet may be able to reduce their need for medication… However… following the ketogenic diet alongside an insulin regimen might (carry) a higher risk of hypoglycemia (low blood sugar).” Medical News Today.

This is why, even though Keto has helped a lot of people — both diabetic and otherwise — the American Diabetes Association (ADA) does not recommend it over any other.

“Every person has different dietary needs,” (Medical News Today).

In light of this, your optimum diet should be based on your current eating habits, preferences, and a target weight or blood sugar level for you, rather than, as Drew puts it: “A band-aid solution… (that can) actually worsen insulin resistance.”

Also, according to him, unless you are incredibly well informed and smart about what you eat, you are liable to consume too much saturated fat on the Keto diet, becoming “lean on the outside, (and) fat on the inside.”

“I don’t think bacon, eggs, butter and coconut oil should make the bulk of your daily calories especially when they’re replacing known healthy foods like fibre-rich, nutrient-dense, and antioxidant-rich fruit, legumes and starchy vegetables.”

All up: whether you are diabetic or not — but especially if you are — check with your doctor (and keep checking in regularly, and getting blood work done) before and during going Keto, and create a specialised diet plan, ideally with a nutritionist.

    What a load of bull this is fake news. Companies are terrified that everyone will move to a healthy keto diet and they will go out of business. A healthy keto diet with lots of low carb vegetables will become a way of life for everyone soon as so many people reverse diabetes type 2 in few months eating healthy keto lifestyle.

  2. George Vilalobos says:

    Agreed, this shows a fundamental lack of understanding of the biology and physiology involved.

  3. Smash Dently III says:

    No kidding, keto is also responsible for LOWERING insulin resistance, not raising it. Gluconeogenesis doesn’t just dump a ton of glucose in your system, it’s done through an extremely inefficient and metabolically undesireable method and mostly used when your brain needs glucose so it’s created, routed, and used. Not just dumped into your bloodstream like toxic sludge from a chemical plant because it can.

  4. Matt says:

    You true believer Keto peeps are in for a rude shock.

  5. Matt says:

    The public doesn’t understand that bio-marker improvement doesn’t equal better health. In ketosis your body is in starvation mode and can throw out misleading readings.

  6. Matt says:

    If you already have a fatty liver and fat in your muscle cells, you are on your way to insulin resistance and type 2 diabetes. If you are lean and healthy insulin resistance is a non issue.

  7. rbfx4x says:

    What load of d cobblers as my father used to say. 7 years keto and full Carnivore for the last 6 months has fixed me and my metabolic issues, skin problems, digestion problems, anxiety/depression. And all that fat and cholesterol has boosted my testosterone meaning muscle gains (that increase insulin sensitivity) and bedroom strength 😉

  8. GenaB says:

    I agree. Doing Keto for the past 5 months, I’m type 2 diabetic, and he’s right. After being strict about my eating, I tried to eat something like a small banana on 1 day and my blood sugar spiked, a lot. I thought no way, something’s weird, so a tried adding a little extra carbs on a weekend, and same thing. Where before those things would never spike me like that. Just as he said, it was like my body was becoming way more intolerant when I introduced a little more carb, after my body learned to use fat for fuel. Now, I eat low carb, (under 50 g a day) sometimes a little higher, aim to get my proteins and try not to worry about staying in ketosis or eating lots of fat. I have been steadily losing the weight and feel better, my glucose numbers are not so touchy either. I think if you are strict doing Keto permanently then there is not going to be an issue, but is that the lifestyle you can live with, otherwise as soon as you go off of it and eat carbs, gluten etc.. the weight comes back, and can be dangerous for us diabetics.

    Great info, where is your data. Ultrasound scan should show the fat on the inside. Fatty liver etc….I also like the see this guys disclosures… I just want to make sure big food isn’t bankrolling his statements. Known healthy foods? where is the study that says starchy vegs are healthy?

  10. Shannon Mahoney says:

    There is one example in his story of a person having issues with their insulin levels and the body becoming insulin resistant. I am sure it is real but it does not address any underlying issues or what this person’s diet actually was. There are a number of different variations of the Keto diet, some of which work well for some folks and not others. If you get a chance take a look at the blood type diet…great information and study into how we eat and how different blood types require different diets to be healthy …I found it to be rather accurate. So for example O type blood types do best on a mostly carnivorous diet while A type blood types do better as mostly vegetarian. I find as an A type that I do not tolerate having loads of meat, while my O type friend do in fact crave it and do very well. Taking that kind of information into the Keto diet helps. Anyhow…I do take what he is saying with a grain of salt…he is by no means an expert, but I do agree that for most people … Not all…on Keto you should be eating a lot of veggies and not a ton of meats and meat fats. Veggie fats are on the whole much better for the body typically and to be honest most of the folks that seem to feel sick it have issues seem to have them using the high meat and meat fats approach. Heck…just taking out wheat and most grains and processed foods and sugars goes a long way.

  11. Matt says:

    Starches are very healthy. Look at the recent study about rice. Humans are specifically evolved to consume starches, because we have multiple copies of the amylase gene.

  12. Matt says:

    Long terms effects of keto is increased rates of mortality due to cardiovascular disease.

  13. Miguel Cervantes says:

    There is this medical term called INSULINIMIA. A condition where the Pacreas overreacts to carbs/starches being introduced in the diet. As a person who was a Type 2 Diabetic for over 11 years and got off all medications and now normal A1C readings from Low Carb/High Fat-Keto Diet, what this “trainer” explains in this article is true but that is the reality of being a diabetic. The damage to the internal system and how our pancreas react to carbs is exaggerated. Taking insulin to counteract a spike in insulin is like adding water to an already full glass of water trying to avoid overspilling the water from the glass, utterly ridiculous! This is definitely a “hit piece” against what works and has the pharma companies very upset or like in the case of Jillian Michaels and Oprah Winfry, angry that this diet is taking from the profits of their personal supplements companies.

  14. PT10981 says:

    Where is that data???

  15. PT10981 says:

    I’ve been practicing nutritional ketosis for 9 years. I dropped 30 lbs back to my high school weight of 175 lbs at 6 ft. I also reversed inflamed joints, enlarge prostate, IBS, heartburn, psoriasis, and herpes virus outbreaks. I am 57 and feel like a 20 year-old again. I have no such problems with adding carbs back-in. It is interesting to read about this reaction. I guess that we are all different. Maybe you are reacting to the insulin injections??.

  16. Aye Bee says:

    So it does not work for 1 person for reason type1 diebetics, therefore it works for no one… including people who do not have type 1. hmm sarcasm —> Thats totally logical.

  17. Keto Rider says:

    Think he needs to visit one of the drs from lowcarbdownunder and get his nutrition properly sorted before he does serious damage to himself.

  18. Robert Kralik says:

    Fat on the inside… I see you big junk. “This fool abandons health to persue junk food” should be the headline.

  19. kitschybc says:

    “Starvation mode” isn’t real. Stop spitting out that meaningless buzz word.

  20. Matt says:

    Ketosis is starvation mode. A natural mechanism the body has to burn fat for energy in times of famine. Because that’s what you are simulating when you are in ketosis, famine. You don’t realize that? Because the body is fueled naturally, primarily with carbohydrates. Namely: Starches broken up into glucose.

  21. Michael Carrato says:

    That’s complete bunk. I know the data you are alluding to: people who eat 200g of carbs every day, which is TEN TIMES what keto people eat. Researchers with an anti-meat bias often promote those garbage studies as “low carb” to scare people into eating plants. Don’t believe it. Read The Obesity Code by Jason Fung. Turned my life around.

  22. Matt says:

    You must be so far down the keto rabbit hole, that you can’t even see the way out.

  23. Matt says:


    Keto increases a person’s chance of sudden death. At lest keto people understand that nutrition is important. In that sense you are half-way there.

  24. Viking says:

    Yes man has been eating Keto since and before the stone age.

  25. Matt says:

    We go into ketogenesis when we run out of yams and grains. It’s a survival mechanism.

  26. Viking says:

    Yes, I am a true believer in Keto. Keto has helped me a billions of others over the centuries. Just look on YouTube for the real life stories how keto has reversed so many Western diseases. See Dr Berg as just one with proof let alone proffessor Tim Noakes

  27. Viking says:

    Diabetes UK has reversed diabetes in millions

  28. Matt says:

    That’s why you don’t eat them raw.

  29. Matt says:

    You don’t get that low-carb diets are a scam? Loose some water weight, then calory restrict. How about just cutting out junk food?

  30. Viking says:

    Just cutting junk food does not work. Carbohydrates make you hungry and create insulin spikes. Once you cut out all carbohydrates you are not hungry anymore so eat way less and lose excess weight. You can live on ketones forever. Man was never meant to eat carbohydrates.

  31. Matt says:

    There are a few falsehoods there. First I’d like to ask you exactly what you mean by carbs? Because complex carbohydrate foods like potatoes and whole grains contain fiber and are actually the most satiating foods and less calorically dense than most other foods. “Man” has evolved to eat carbohydrates as the primary food source, that’s why we have a glucose energy metabolism.

  32. Matt says:

    Food makes you hungry, no, no it doesn’t.

  33. Matt says:

    You are actually hacking your psychology because fat causes dopamine spikes. Fat has twice the calories of carbohydrates.
