Yancy has seen similar results in his practice. “Carbohydrate intake is the main driver of blood sugar. So if you’re able to lower blood sugar by reducing carbohydrate intake, then you may be able to reduce diabetes medication,” he says. “We’ve seen people come off of hundreds of units of insulin just by changing the way they eat, and that can happen really quickly, in just a few weeks.”
But there is evidence that low-carb diets may increase metabolism, according to a paper published November 14 in BMJ. Researchers found that overweight adults who lowered carbohydrates and added more fat into their diets burned about 250 calories more each day than people on high-carb, low-fat diets. The study is impressive because it's the largest, most expensive, and controlled study of its kind.
The only evidence I could find for the long-term safety of a keto diet is from one 12 month trial. As a result of the study, the researchers found that overweight adults with elevated A1c that followed the keto diet experienced more significant reductions in A1c, lost more weight, and decreased their medications more than those instructed to follow a moderate-carbohydrate, calorie-restricted, low-fat diet.
It’s only dangerous to not get enough carbs at each meal if one is taking too much meds or insulin for the amount of carbs they are eating! Restricting carbohydrates doesn’t lead to hypoglycemia unawareness, but having lots of lows and lots of highs will (and decreasing insulin and carbs leads to way fewer highs and fewer lows, or at least it can). On the other hand, being in ketosis does make low blood sugars less negative as an experience. I still feel my lows just fine, but they are less of an emergency because my brain still works (feeding on ketones) and by body doesn’t freak out and release tons of adrenaline that then makes me want to eat a house. Mind you, I still wake up and know immediately if I’m low, I know from experience and how it feels in my head and body but without the crazy shakes. This is not unawareness but it is less reactive.
What about fruits and vegetables? All fruits are rich in carbs, but you can have certain fruits (usually berries) in small portions. Vegetables (also rich in carbs) are restricted to leafy greens (such as kale, Swiss chard, spinach), cauliflower, broccoli, Brussels sprouts, asparagus, bell peppers, onions, garlic, mushrooms, cucumber, celery, and summer squashes. A cup of chopped broccoli has about six carbs.

I know a few people who struggle with keeping on the low carb diet and staying in ketosis. They introduced me to a exogenous drink called keto/os that is a natural energy drink that contains ketones. It gets you into ketosis within an hour!!! This can be tested in the blood and they showed me the results and it works!!! Not only that but it dropped their blood sugars as well. I am now on the product myself for other reasons but just thought I would share it. Let me know if you want more info.
Missing Nutrients. One of the biggest concerns for dietitians is the keto diet’s lack of key foods. Many question the eating plan’s impact on the development of certain chronic diseases. Without milk, for example, getting enough calcium and vitamin D for sturdy bones becomes a challenge. Take away whole grains, fruit, beans, and potatoes, and it’s nearly impossible to consume enough potassium for healthy blood pressure or enough fiber to stay regular. And unless you’re eating lots of low-carb, leafy green vegetables, you miss out on vitamins A, C, K, and folate, too.
The diet calls for consuming high amounts of fat, a moderate amount of protein, and a very limited amount of carbs. It’s usually broken down to 75, 20, and 5 percent of your daily calories, respectively, says Pamela Nisevich Bede, RD, a dietitian with Abbott’s EAS Sports Nutrition in Columbus, Ohio. Compare that with the typical American diet — which is usually 50 to 65 percent carbs — and it’s safe to say this is a completely different way of eating, Nisevich Bede says.
While these findings are preliminary, in one study of mice, the keto diet helped reduce anxiety. The research suggests this could be due to the protective brain benefits of intake of healthy fats and low levels of sugar. A follow-up study found that mice exposed to a ketogenic diet while in utero showed less susceptibility to anxiety and depression than mice born to mothers who were not on the keto diet. Here’s what it’s really like to follow the keto diet.
In a March 2018 blog post, Dr. Ede provides a range of very helpful tips for anyone already on mood-altering or psychiatric medications who want to try a ketogenic diet, such as how to talk with your psychiatrist or mental-health provider and what laboratory metabolic tests the doctor should order to help monitor your response to the diet. Most importantly, she provides details about some specific medications — notably specific antipsychotic medications, anticonvulsant medications, and lithium — that should be carefully monitored.
It's important to note that the drop-out rate was substantial and reports of symptomatic hypoglycemia 1-5 episodes) were experienced by 69% of those in the study. The mean carbohydrate intake was 35 grams (+/- 15) daily. Based on self-reported results, the change in HbA1c was -1.45% (+/- 1.04, P < 0.001) with an average HbA1c of 7.2% associated with greater hypoglycemia; yet, these results are comparable to other study findings. The average blood glucose levels were 104 mg/dL (+/- 16). 2 Final lipid profiles were mixed. The results were similar for adults and children.
But wait, there’s one loophole. Have polycystic ovary syndrome (PCOS)? Then the keto diet may help regulate your periods. “Women with PCOS have high insulin levels, which cause sex hormone imbalances,” notes Yawitz. In a small study published in the journal Nutrition & Metabolism, subjects with PCOS following a ketogenic diet for six months noted improvements in their menstrual cycles — and a small number of women became pregnant, overcoming previous infertility obstacles. “This study was very small, so we can’t make recommendations for all women with PCOS based on its findings,” says Yawitz. “And really, any diet that leads to weight loss should help in PCOS.”
Obesity is one of the principle risk factors for diabetes and following a ketogenic diet has been shown to help with weight loss. According to scientific article published in 2014, “A period of low carbohydrate ketogenic diet may help to control hunger and may improve fat oxidative metabolism and therefore reduce body weight.” Many prediabetics struggle with being overweight so a keto diet can help promote weight loss, which can help to decrease the chances of developing full blown diabetes.
Look, the good doctor is right – he only forgot to stress “portion control” which is why many fanatical dieters are so kee-jerk reactive to any discussion – odds are you over ate like a hog before your keto diet, and are weak and insecure in your diet plans. Eat EVERYTHING in small amounts, and you will live long and prosper. The only thing to avoid are processed foods. Cook your meals from scratch using quality ingredients.
Common complications of diabetic ketoacidosis include very low blood sugar, or hypoglycemia, and swelling of the brain (cerebral edema). As such, when a person is in ketoacidosis, there is such a high level of ketones produced that can push a person into cardiac arrest (heart attack) or kidney failure. Hence, the very important reason for taking occasional keto breaks go give your body a bit more nourishing carbs.
“If not done right, this diet can cause havoc on our bodies,” says Mancella. “As a society, we’ve turned to a culture of restriction and extremes in order to obtain unrealistic beauty and aesthetic standards without considering the long-term consequences. This diet doesn’t only affect metabolism, but also every other component of our bodies. By introducing potential vitamin and mineral deficiencies, we’re possibly trading the present moment for quality ones in the future.”
What sort of negative health effects might an overly acidic pH level contribute to? A few include: bone loss, muscle loss, and higher susceptibility to frequent infections or illnesses. One way to track if your body is adapting well to an alkaline diet is testing your urine pH level. The pH scale ranges from 1–14, with seven being neutral and anything higher than seven beings alkaline. The goal is to ideally have a urine alkaline pH level between of 7.0–7.5 (a number that is slightly more alkaline than acidic).
Dr. Campos, it is unfortunate that you retain the medical community’s negative stance on the ketogenic diet, probably picked up in medical school when you studied ketoacidosis, in the midst of an obesity and type II diabetes epidemic that is growing every year, especially among populations who will never see the Harvard Health Letter. The medical community has failed in reversing this trend, especially among children, and the public is picking up the tab, in the form of higher health insurance premiums to treat chronic metabolic diseases which doctors cannot cure. The ketogenic diet does not bid its adherents to eat unhealthy processed meats, and the green leafy vegetables that it emphasizes are important in a number of nutritional deficiencies. People lose weight on the ketogenic diet, they lose their craving for sugar, they feel more satiety, they may become less depressed, their insulin receptors sensitivity is improved, and these are all the good outcomes you fail to mention. There is a growing body of research which demonstrates the neuroprotective effects of the ketogenic diet to slow cancer progression, as well as diseases like Parkinson’s and Alzheimer’s, for which there are no effective medical treatments. Please respect your patients by providing them with evidence-based medical outcomes, not opinions.
I have patients that have lost tons of weight on keto. They do go off some meds. I also have people who eat a moderate amount of good carbohydrates, and they have lost tons of weight, and been taken off meds, had improved markers, even reversal. I think both approaches work, as I have seen in practice. Many people cannot stay on a keto diet forever. I for one, prefer to have some carbohydrates. I try to pick the right ones. If this works for you, then just be sure to have some medical supervision, which it sounds as though you are doing.
Luiza Petre, MD, a board-certified cardiologist and weight management specialist in New York City, suggests focusing on eating more low-carb, fiber-rich foods that can help beat this bowel issue. “Try fibrous vegetables, such as broccoli, asparagus, and cabbage, consume more fat like MCT oil, coconut oil, or ghee, and, as always, drink plenty of water,” she says.
Avocados are the poster child of “good fats.” This type of fat, often found in plant-based foods, can be separated into polyunsaturated fats (found in fish and walnuts) and monounsaturated fats (found in avocados, flaxseed oils, nuts and seeds). There’s evidence that replacing saturated fats with “good” unsaturated fats can lower the risk of heart disease and help prevent insulin resistance.4
Obesity has become a serious chronic disease in both developing and developed countries. Furthermore, it is associated with a variety of chronic diseases (1–4). It is estimated that in the United States alone approximately 300,000 people die each year from obesity-related diseases (5,6). Different methods for reducing weight using reduced calorie and fat intake combined with exercise have failed to show sustained long-term effects (7–9). Recent studies from various laboratories (10,11), including our own (12), have shown that a high fat diet rich in polyunsaturated fatty acids (ketogenic diet) is quite effective in reducing body weight and the risk factors for various chronic diseases. The ketogenic diet was originally introduced in 1920 (13). In this diet, the fat to carbohydrate ratio is 5:1. While there was a significant decrease in the weight of obese patients who were on a ketogenic diet (12), the reverse occurred when the diet changed to one high in carbohydrates (14).
The high-fat, very low-carb keto diet lets you enjoy lots of avocado, butter, bacon and cream—but requires cutting way back on added sugars, most processed foods, sweets, grains, and starchy veggies (whew). The eating plan is mega-popular among Hollywood A-listers (including Halle Berry, Megan Fox, and Gwyneth Paltrow); but if you don’t have a private chef who can futz with fats to make delicious meals and snacks, the carb-restricted lifestyle can be extremely challenging to follow.
Best animal proteins are wild salmon, tuna, trout, shellfish, red meats, and poultry. The oil, protein sources will help balance your omega 3s. You only need 70 to 80 grams of protein a day, depending on your lifestyle and your body's physical needs. Protein requirements are different for everyone. Here are some good protein sources to include in your diet.
Make things yourself. While it’s extremely convenient to buy most things pre-made or pre-cooked, it always adds to the price per pound on items. Try prepping veggies ahead of time instead of buying pre-cut ones. Try making your stew meat from a chuck roast. Or, simply try to make your mayo and salad dressings at home. The simplest of things can work to cut down on your overall grocery shopping.
Lele says that it’s important to remember that, while keto is a “high fat” diet, the goal is to use your body fat as an energy source, not the fat that’s on your plate. “You don’t need to necessarily add more fats to your diet to adhere to keto. For instance, if your dinner consists of avocado, bacon, and eggs, you really don’t need to add butter to that to make it ‘more keto’,” she says.
Those following the keto diet are advised to restrict carbohydrates to just 50 grams a day at the most, although hardcore keto dieters recommend consuming just 20 grams—about the equivalent of half a hamburger bun or a single banana. Instead, high-fat foods are prioritized, like avocados, olive oil, nuts and butter. Beef and chicken, which have no carbs, are staples of the ketogenic diet, although protein should only make up 20 percent of your daily caloric intake.
There are people who say that keto helps your athletic performance, and those who say it hurts it. "The literature is mixed on how an ultra low-carbohydrate diet like the keto diet affects athletic performance," says Grant Cox, C.S.C.S., head coach at Iron Tribe Fitness. But one thing is pretty clear: "A lot of it points to consistent decreases when athletes are looking for maximal power output (in weightlifting, vertical jumps, sprinting, etc.). Along the same lines, you'd be hard-pressed to put on weight and strength on such a low carbohydrate diet," he says.
Ketoacidosis occurs mainly in people with type 1 diabetes if they do not take insulin. In diabetic ketoacidosis (DKA), blood sugar and ketones rise to dangerous levels, which disrupts the blood’s delicate acid-base balance. People in ketoacidosis feel extremely ill and experience profound dehydration, vomiting, abdominal pain, and weakness. DKA requires hospitalization so that IV fluids and insulin can be given to gradually and safely lower blood sugar.
While many health care providers aren’t comfortable recommending the keto diet for people with diabetes, there’s a substantial body of research indicating that it can help with weight loss, reduce the need for medication, and even lower A1C into the non-diabetes range. It’s so effective that when researchers assigned 349 volunteers with type 2 diabetes to follow either a keto diet or a traditional diabetes eating plan (the makeup of that plan wasn’t defined in the study) for one year, they observed some powerful results. While the people on the “diabetes diet” didn’t experience any positive movement in their A1C, body weight, or medication requirements, those on the keto plan reduced their A1C from 7.6 to 6.3 percent, shed 12 percent of their body weight, eliminated their need for sulfonylurea medication, and lowered or reduced their need for insulin by 94 percent. The results were published in 2018 in the journal Diabetes Therapy.
It takes more work to turn fat into energy than it takes to turn carbs into energy. Because of this, a ketogenic diet can help speed up weight loss. And since the diet is high in protein, it doesn't leave you hungry like other diets do. In a meta-analysis of 13 different randomized controlled trials, 5 outcomes revealed significant weight loss from a ketogenic diet.
According to Dr. Cabeca, “Fasting is a key aspect of a healthy diet and has many anti-aging effects.” In particular Dr. Cabeca recommends fasting to women during or after menopause due to it’s anti-aging effects. For example, a 2016 study published in the Journal of the American Medical Association found that when women went 12.5 hours between dinner and breakfast (a common form of fasting), the overnight fast seemed to help improve immune system functioning to the point that it reduced their risk for breast cancer. (03)
The more recent study was conducted online to ascertain if this online approach proved effective in eliciting weight loss.1 Dr. Saslow's team randomly assigned the 12 participants to the Keto diet and lifestyle improvement group and another 13 individuals to the traditional low-fat diet known as the Plate Method,1 supported by the American Diabetes Association.
The study concludes, “The ketogenic diet appears to improve glycemic control. Therefore, diabetic patients on a ketogenic diet should be under strict medical supervision because the LCKD can significantly lower blood glucose levels.” Previous research has also shown that for patients with type 2 diabetes, long-term administration of the keto diet lowered body weight, improved blood sugar levels and can result in a smaller needed dose of antidiabetic medication.
MCTs are natural sources of essential healthy fats for energy. They are easily digestible and absorbed by the body, providing instant but lasting energy. Including MCT oil in the keto diet can stabilize blood sugar levels and enhance the production of ketones. Since that is the goal of your keto diet, optimal blood ketone levels, MCT Oil is a no-brainer.
