Anna Taylor, RD, CDE, a licensed dietitian at the Cleveland Clinic in Ohio, says very-low-carb diets can hurt people with type 2 diabetes if done incorrectly. She and Keratsky say it’s important that anyone with diabetes who wants to try a low-carb or ultra-low-carb diet meet with a dietitian or physician to create a plan and make sure their eating style won’t react negatively with their current medicines.
Nuts, the second food to watch, contain a fair amount of carbohydrate, and it’s very easy to unwittingly scarf down large quantities. Cashew nuts are among the worst carb-wise – you’ll find that they contain around 20% carbohydrate by weight. For someone following a strict keto diet with a 20 grams of carbs per day allowance, this means that consuming 100 grams (which happens in a flash!) will have filled their daily quota. Peanuts tend to be around 10-15% carbohydrate – not putting them in the clear either.

I, too, am finding the keto diet to be beneficial. My weight is moving down. My recent A1c was 5.7. I am consistently below 90 each morning when I check my blood. I am learning to adapt my cooking to the needs of maintaining this way of eating. I have incorporated walking because now I FEEL like it. I don’t feel deprived. I feel empowered. No medications for diabetes!


Ketogenic diet for diabetics is a highly controversial topic, but we will break down everything here for you! As a Certified Diabetes Educator (CDE), I have to tell you from the start I will have a biased view here. Sorry, but I feel that I need to be completely honest right up front! I will however, present all the evidence that is available currently on the subject.

Many diets, including Atkins and the keto diet, fit into this umbrella. A typical low-carb diet limits carbs to less than 60 g daily, but this can vary, according to the Mayo Clinic. (15) In a September 2015 review published in PLoS One, people following low-carb diets saw modest weight loss — although study authors note that long-term effects of the diet require further research.

Control Your Environments. Another simple strategy to help cut calories is to control your environment -- everything from stocking your kitchen with lots of healthy options to choosing the right restaurants. That means avoiding the temptation by staying away from all-you-can-eat restaurants. And when it comes to parties, "eat a healthy snack before so you won't be starving, and be selective when you fill your plate at the buffet," suggests Ward. Before going back for more food, wait at least 15 minutes and have a big glass of water.

“Just because the scale isn’t moving, doesn’t mean that you are making zero progress toward your fitness goals and dream body,” explains Mike Roussell, PhD, co-founder of Neutein, a dietary supplement meant to improve memory and performance. “It’s easy to think you’ve hit a plateau when you don’t see additional weight loss on the scale, but that’s not always truly the case."
The Mediterranean diet wasn’t built as a weight loss plan — in fact, because it wasn’t developed at all, but is a style of eating of a region of people that evolved naturally over centuries, there’s no official way to follow it. But it’s popular because it’s a well-rounded approach to eating that isn’t restrictive. Two of the five Blue Zones — areas where people live longer and have lower rates of disease — are located in Mediterranean cities (Ikaria, Greece and Sardinia, Italy). (2) These places are known for having some of the lowest rates of heart disease and cancer worldwide. (3)
I have been on a low carb diet for over 2 years. I was diagnosed a diabetic with a blood glucose over 400 mg/dl and an A1C of 12. I tried my doctors recommendations for about a year and took all the medications they told me to take. not much changed. they wanted to put me on insulin after a year. I told my doctor that I thought I could control my condition with diet and he said, “you are to far gone for that”.
In Asia, the normal diet includes rice and noodles as the main energy source, making their elimination difficult. Therefore, the MCT-oil form of the diet, which allows more carbohydrate, has proved useful. In India, religious beliefs commonly affect the diet: some patients are vegetarians, will not eat root vegetables or avoid beef. The Indian ketogenic diet is started without a fast due to cultural opposition towards fasting in children. The low-fat, high-carbohydrate nature of the normal Indian and Asian diet means that their ketogenic diets typically have a lower ketogenic ratio (1:1) than in America and Europe. However, they appear to be just as effective.[53]

Benefits It packs lycopene, a powerful antioxidant that is associated with a reduced risk of some cancers, like prostate and breast. Other components in tomatoes may help reduce the risk of blood clots, thereby protecting against cardiovascular disease, according to a review published in December 2013 in the journal Annual Review of Food Science and Technology.

The remaining calories in the keto diet come from protein — about 1 gram (g) per kilogram of body weight, so a 140-pound woman would need about 64 g of protein total. As for carbs: “Every body is different, but most people maintain ketosis with between 20 and 50 g of net carbs per day,” says Mattinson. Total carbohydrates minus fiber equals net carbs, she explains.

Keto decreases inflammation and improves brain function — so much so that Alzheimer’s patients who switch to a keto diet actually begin to recover their brain function, which up until now was unheard of.[20][21][22][23][24] So there’s that. (Dale Bredesen and Mark Hyman have discussed these on the Bulletproof Radio podcast. Check out Dale’s episode here, and Mark’s here.)  

Think of it as intermittent fasting 2.0 – only a bit more complicated. Ready? Here goes. There are three windows: one to get you started, one to help you reach your goal weight and a maintenance plan. You eat within a 12-hour, 14-hour or 16-hour window depending on which phase you’re in. But what you eat counts, too. The ‘green light’ lists of foods changes with every phase. Still there?
This is a wealth of information. My husband and I are starting the keto diet tomorrow and I knew nothing about it. When I sat down to look up information about it, I found this. Thank you! This is everything I need to know in one place. We are not as healthy as we’d like to be and I am optimistic this will help us obtain our goals, along with an exercise plan.
Eating low-carb paleo means removing items like rice, pasta, and legumes from your diet completely, but the carbs you eat will be from vegetables like fruit, beets, sweet potatoes, and leafy greens, such as spinach and kale. The diet also cuts out processed food plus foods allowed on other low-carb diets, including milk and cheese, and some people have an easier time sticking with the diet when more carbs are included.
By restricting carbs to the degree that the keto diet recommends, you will stimulate the production of ketones and eventually enter nutritional ketosis. As a result, you will start burning more ketones for fuel. Ketones have also been found to help increase weight loss, lower glucose and insulin levels, decrease insulin resistance, and improve energy efficiency. [25] [26]

“Acknowledge that health is an onion; it's layered and complex, and isn't just about nutrition,” Moreno says. “Map out your health and wellness path by creating lists of issues vs. goals in your life within the realms of nutrition, movement, sleep, stress, spiritual, social, and medical issues. You’ll learn to see yourself as an amalgam of health traits and not just a roster of foods you ate in the last week.”
– When eating the Mediterranean way, you’ll notice that we don’t eliminate any food groups. But we do rely more on vegetables, fruits, legumes and grains to supply more of what we eat. We also eat mostly lean proteins. So with that, if eating tempeh or other soy-based foods or if drinking green tea is something you enjoy, then that is up to you…and I would again encourage figuring that out with an RD or someone who can better assess your specific needs and advice you accordingly.
Carbohydrate Restriction. To help people with diabetes manage their blood sugar levels, doctors will typically prescribe a diet that mostly consists of low glycemic index foods. [23] However, according to the research, restricting overall carb intake to the point of following a keto diet may be the best way to improve the many biomarkers relevant to diabetes. [24] In fact, this dietary strategy has been proven to be helpful for the management of type 2 diabetes and type 1 diabetes.
That’s why the Bulletproof Diet uses cyclical nutritional ketosis, and why on days when I eat carbohydrates, I always have Brain Octane Oil so my cells have a steady supply of ketones. This builds metabolic flexibility: you can eat fat and carbs and your body will use them both, which is the goal. You want to be resilient and full of energy no matter what, and that means you want cells strong enough to burn whatever you give them.
Thank you for your wonderful comments Marcia. To share more about me personally with you all…I am not a completely non-diabetic Certified Diabetes Educator. I found out I had Prediabetes 15 years ago when I became a Diabetes Educator. I tested my own A1c and found it was 5.8%. The incredible news? There have been years when my A1c dropped to a normal level of 5.4%…out of the prediabetes range. My last A1c in May was 5.8%, so I still have Prediabetes 15 years later, but not diabetes, and without any medication, just the sensible diet I’ve discussed and exercise, so I really am living with this. I feel it everyday, I wonder what my A1c is going to be just like you every 6 months when I go to have it drawn.
A: You’ll find a detailed menu earlier in this article (also, recipes from Everyday Health!), but generally, you’ll want to make plants and whole grains the stars of your plate. If you look at a Mediterranean diet food pyramid, sweets are up top (indicating they should make up only a small part of your diet), followed by meat and dairy, and then fish. Last are fruit, veggies, and whole grains (suggesting they can be eaten liberally). Also, enjoying food with friends and family is a tenet of the eating approach, so make your meals a social affair!
Keto decreases inflammation and improves brain function — so much so that Alzheimer’s patients who switch to a keto diet actually begin to recover their brain function, which up until now was unheard of.[20][21][22][23][24] So there’s that. (Dale Bredesen and Mark Hyman have discussed these on the Bulletproof Radio podcast.

Full disclosure: I have followed a low-carb diet for nearly a decade and find no problem adhering to it. I’ve lost weight and all my cardiovascular biomarkers have improved. Moreover, I’ve studied the science and history behind low-carbohydrate diets, so beyond my personal experience, I bring an evidence-based perspective. (Previously, for 25+ years, I adhered faithfully to a “mostly plants” regimen of fruits, veggies, and whole grains, including my own homemade 7-grain bread, while exercising religiously. Yet during that time my blood lipids were unhealthy, and I never could shake an extra 10-20 pounds.)
Using the Bulletproof Diet, including Brain Octane Oil every day for long periods of time, and eating carbohydrates some of the time but not always, avoiding inflammatory foods, and using Bulletproof Intermittent Fasting, I was able to recently test with perfect insulin sensitivity — I scored a one on a scale of 1 to 120 (see my numbers below). I also had above average glucose tolerance. That’s metabolic flexibility by the numbers!
Part of slimming down involves a simple, sensible exercise and an easy-to-follow nutrition plan. This full week of meals will take the guesswork out of grocery shopping and prepping with nutritionist-approved breakfast, lunch, and dinner ideas. If you have a higher activity level, check out these 1,300-, 1,400-, 1,500-, and 1,800-calorie meal plans as well.
Susan answered, “White bread is so refined that the nutrients are stripped down, again it’s a simple carbohydrate where when a diabetic eats something, there blood sugar will rise and you get a boost of energy. This is the difference between a whole grain and a white-refined bread, once you consume that bread your blood sugar will rise for a little while and you’ll feel energized but the whole grain has better effect on your blood sugar, sustaining that energy over a longer period of time, avoiding the ‘crash and burn’ some feel when eating white bread. Keep in mind that in white bread all of the nutrients have been processed out of the food.” The other difference, you can literally, “Taste the difference when you eat one over the other.”
What the expert says: ‘Over 50 years ago researchers realised they didn’t have to restrict energy every day and they still got a protective effect. In animals, these diets were shown to reduce visceral fat, oxidative stress and reduce cell proliferation, which is involved with the development of cancer. The models that were used in humans were two consecutive days of 650kcal then five days following a normal, healthy diet, versus a healthy med diet of 1500kcal.
“Regardless of how solid they are, your diet and exercise plans won’t work if you aren’t sticking to them. You’ve made a commitment to yourself, so come through with it,” Roussell says. As you plan your meals or snacks, Roussell suggests putting an X over it on your menu map. If you skip a meal or eat something that isn't in your plan, circle that meal. At the end of each week, count the number of meals you ate according to your meal plan and divide that number by the total number of meals, snacks, and post-workout smoothies you had planned, then multiply it by 100.
Having tempting, unhealthy foods in your home is one of the biggest reasons for failure when starting any diet. To maximize your chances of success with the keto diet, you need to remove as many triggers as you can. This crucial step will help prevent moments of weakness from ruining all your hard work.If you aren’t living alone, make sure to discuss with your family or housemates before throwing anything out. If some items are simply not yours to throw out, try to compromise and agree on a special location so you can keep them out of sight.
And what benefit you will have with “moderate” diets that let you eat bread and others carbohydrates but high insulin ? remember that it is critical to not only look after glucose levels on blood, it is very very important to reduce your intake of insulin to avoid a lot of diseases including metabolic syndrome for high insulin and insulin resistance.
But DASH—which stands for Dietary Approaches to Stop Hypertension—is far from a fad diet. Created by the National Heart, Lung, and Blood Institute (NHLBI), the DASH Diet is designed to improve health in people with high blood pressure, a.k.a. hypertension. (In the U.S., one out of every three adults has high blood pressure, according to the Centers of Disease Control and Prevention.) U.S. News & World Report has named the DASH Diet the best overall diet for the past eight years.

Cyrus Khambatta earned a PhD in Nutritional Biochemistry from UC Berkeley after being diagnosed with type 1 diabetes in his senior year of college at Stanford University in 2002. He is an internationally recognized nutrition and fitness coach for people living with type 1, type 1.5, prediabetes and type 2 diabetes, and has helped hundreds of people around the world achieve exceptional insulin sensitivity by adopting low-fat, plant-based whole foods nutrition.
On keto, I’ve adjusted my basal rates and I barely need to bolus at all. My blood glucose numbers have definitely improved and what I find really extraordinary is that I’m needing about 60% less total daily insulin, than I did before starting keto. What’s even more fascinating to me is seeing a steady straight line across my pump for 6, 12, and even 24 hours – no crazy spikes or dips in my blood sugar.
Nonetheless, Fung told Live Science that she thinks the study clearly demonstrates the potential for a ketogenic diet to have a detrimental effect in humans. And, until researchers better understand the risks of those detrimental effects, she suggested that people consider other ways of accomplishing their health goals, such as trying a less-restrictive diet.
If you’re on the ketogenic diet, be sure to test blood sugar levels throughout the day to make sure they are within their target range. Also, consider testing ketone levels to make sure you’re not at risk for DKA. The American Diabetes Association recommends testing for ketones if your blood sugar is higher than 240 mg/dL. You can test at home with urine strips.
