“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.”
My son started the Keto Diet (not perfectly) with the ok of his Dr and a Different Oral Chemo at the same time. Last Tuesday an MRI indicated no new growth or no new tumors. We don’t know if the new Chemo, Keto diet, lots of prays or what has stopped the tumors from growing.I found your site after looking for possible adverse reactions to Keto Diets, and appreciate your research. His platelets are low now and never have been low before. This is stopping the next Chemo treatment. I understand that being on Chemo for 12 months could have created the low platelets and now the possibility that the Keto Diet could also be causing low platelets is frustrating. They will do a new blood test Tuesday to see if the platelets have increased. Any suggestions about how if possible to increase the platelets on the Keto Diet would be helpful.
Thank you for your objective review of the Keto Diet. I am not overweight but decided to try the Keto lifestyle because I have a lot of inflammation issues, including asthma and osteoarthritis. I had also been experiencing uncomfortable intestinal issues. I have been following the Keto lifestyle for 4 1/2 weeks, and I feel so much better- especially my stomach! I am eating a ton of leafy greens, broccoli and cauliflower. I am also enjoying Brussel sprouts, whole avacados and zucchini. I think the reason this is working well for me is because my body chemistry loves all the vegetables, good fats and protein. I also think that taking away sugar has had a big impact on how I feel. I’m just not eating grains and sugar. lots more veggies, berries, and consciously incorporating healthy fat. My stomach is flat again, and I have no more bloating or constipation. I have only lost 5 pounds, but I think my system is clean and operating better than it has in years. My point is that every person’s body chemistry is different. The Keto lifestyle seems to be what My body needed to feel my best. I did experience “the Keto flu” about a week into it, but it was short lived. I think that to be successful it is really important to eat a wide variety of veggies and good fats every day.
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.
Another potential benefit of the ketogenic diet is that it is thought to improve insulin sensitivity5,6. Prediabetics and diabetics are often referred to as “insulin resistant” because their muscle, fat, and liver tissues do not respond properly to insulin. When the pancreas can’t meet the body’s need for insulin, excess glucose builds up in the bloodstream, contributing to diabetes and other medical conditions7.
Abbey, I appreciate all the work you put into this but there are a few things you missed. Not all oils are keto friendly. Vegetable oils are a huge no-no which was not mentioned. Regular mayo usually contains soybean oil which should be avoided. You also missed that foods with preservatives are a no-no which excludes some cheeses (you said enjoy all the cheese you like). Processed sliced cheese or pre-shredded cheese in a bag at the grocery store contains preservatives. Ever notice how shredded cheese in a bag never sticks to itself but when you shred your own cheese it sticks? Preservatives. Most nuts are okay but peanuts are a legume and should be consumed in very small amounts or avoided altogether. Don’t go crazy either, nuts do have carbs. I don’t eat more than a half cup a day of salted almonds. That said, you could have mentioned that getting salted nuts is ideal as you do excrete more salt and other minerals in your urine (eating keto is diuretic so attention must be paid to salt, potassium, magnesium, etc. as you did mention) so finding simple ways to add salt and other minerals is helpful. I also take a multi-vitamin daily. You mentioned you cannot do high intensity workouts. You are not supposed to do high intensity workouts as elevating your heart rate too high actually stops the fat burning process in your body. Your heart rate should be 180 beats minus your age +/- 5 beats depending on fitness level. A 40 year old obese person shouldn’t go over 135 beats/min during a workout as that is the optimal fat burning window. Higher than that and your body reverts to storing fat reserves thinking it will run out if it keeps this pace. Which bring me to metabolism. Its been long believed a high metabolism is good. A high metabolism leads to more hunger (because you’re burning glucose faster), ingesting more food, and typically gaining more weight. Slowing your metabolism down AND teaching your body to consume slow burning ketones instead of quick burning glucose puts less stress on your liver mainly and on your body in general. There’s a lot more but this is getting long so I’ll finish with this. You said this diet focuses on quantity of food and not quality. This is confusing to me….wouldn’t organic and grass-fed meats, be of better quality than non-organic and grain fed meat? (they feed animals grains to fatten them up….shouldn’t that be a huge warning sign for us?). Is food without preservatives not better quality than food with preservatives? Aren’t beverages with no sugar or artificial sweeteners of better quality than sugar/artificial sweetener-filled beverages? I’ve never seen any keto advocate advise ignoring quality foods, in fact its quite the opposite.
One argument against the consumption of a high fat diet is that it causes obesity. The major concern in this regard is whether a high percentage of dietary fat promotes weight gain more than a low percentage of fat intake. Because fat has a higher caloric density than carbohydrate, it is thought that the consumption of a high fat diet will be accompanied by a higher energy intake (31). On the contrary, recent studies from our laboratory (12) and many other laboratories (24,32–34) have observed that a ketogenic diet can be used as a therapy for weight reduction in obese patients.
Research shows there is a weak relationship between levels of dietary cholesterol and blood cholesterol.6 The effect isn’t the same for everyone either. There are “responders” and “non-responders” to dietary cholesterol; some people experience higher fluctuations in blood cholesterol levels according to the amount of cholesterol they eat, while others are more stable regardless of diet.
In January 2017, at 63 years of age, I was diagnosed with type 2 diabetes. I had probably been living with it unknowingly for years. In 2009 my doctor recommended the South Beach diet because I was showing blood-sugar levels that were considered pre-diabetic. I stayed on it for a while but then, as with all other diets I’ve tried in my life, I failed and put all the weight back on, plus some. When I was officially diagnosed last year with type 2 diabetes I was a whopping 284 pounds (129 kg). I was always fatigued, could barely walk a block without getting tired and my health was failing.
In part, keto diet weight loss is a real thing because high-fat, low-carb diets can both help diminish hunger and boost weight loss through their hormonal effects. As described above, when we eat very little foods that supply us with carbohydrates, we release less insulin. With lower insulin levels, the body doesn’t store extra energy in the form of fat for later use, and instead is able to reach into existing fat stores for energy.
Adding salt to food might be new to you, since most people are used to being told to limit salt intake. However, when you’re eating a ketogenic diet of less than 60 carbohydrates each day, you’ll need to make up for this loss of salt. That being said, those with high blood pressure who take medication should check with their doctors before making a change.
The keto diet can be an effective way to reduce excess body fat but there are several cons that should be noted by anyone wanting to follow this eating plan, says Ms. Zarabi says. In fact, the keto diet has serious risks. For one thing, it’s high in saturated fat, which has been linked to heart disease. Additionally, a nutrient deficiency and constipation could occur since the keto diet is very low in fibrous foods such as fruits, vegetables, and whole grains.

Dementia and Alzheimer’s Disease A small study published in February 2013 in the journal Neurobiology of Aging found that older higher-risk adults on a keto diet experienced better memory functioning after just six weeks. (11) Some experts, like Richard Isaacson, MD, director of the Alzheimer’s Prevention Clinic at Weill Cornell Medicine and NewYork–Presbyterian in New York City, support low-carb diets for patients as one way to delay brain aging and possibly Alzheimer’s disease, the most common form of dementia.
While there have not been large studies that show the relationship between the ketogenic diet and cancer, we will be publishing a case study about that topic. The author failed to comment that pediatric patients with epilepsy are on the diet for usually about 2 years with no harmful effects. Before the false studies about heart disease and fat, the low carb diet was a respected way to lose weight. Studies into our metabolism show we can use both fat and carbohydrate as fuel. So stepping away from our high carb diet- I am sorry to say that we eat more carbs since the 70s with most of it processed and we now use high fructose corn syrup to sweeten products and we have a wide spread childhood obesity problem. If cholesterol is a concern try plant sterols and stenals to block cholesterol from the receptors in the body. So much more can be said about a keto diet than this article states
Participants were recruited from the Durham Veterans Affairs Medical Center (VAMC) outpatient clinics. Inclusion criteria were age 35–75 years; body mass index (BMI) >25 kg/m2; and fasting serum glucose >125 mg/dL or hemoglobin A1c >6.5% without medications, or treatment with oral hypoglycemic agents (OHA) and/or insulin. Exclusion criteria were evidence of renal insufficiency, liver disease, or unstable cardiovascular disease by history, physical examination, and laboratory tests. All participants provided written informed consent approved by the institutional review board. No monetary incentives were provided.
I have been a type 1 diabetic for most of my life. I live a very active lifestyle of long distance running and hiking. I’ve always had a very healthy diet, but would still have those after meal blood sugar spikes that would leave me feeling unwell. I decided to try the keto diet to see how my blood sugar did It’s been amazing. I’ve cut my insulin in half and my head is clear. I no longer have the brain fog. I sleep better and have more energy. I have been doing it for a year and have no desire to go off of it.
The keto diet is NOT what you seem to picture. I laughed at your description as I was eating lamb chops, cauliflower rice, broccoli, followed by cheesecake. How deprived I was! You should relook at what the diet really is. By the way, my cardiologist highly recommends keto. Most people see a drastic decrease in their triglyceride/HDL ratio. Looking at total cholesterol or LDL alone is 20 years out of date! Even the AHA has caught up, and now says that it’s NOT how heart health should be judged.
By now, most of us have heard about the ketogenic diet. Whether it's because of the benefits of eating high-fat and low-carb, or because you can eat cheese all day long, it's officially become one of the hottest diets of the year. It may not be easy to cut out all the carbs, but emerging research suggests that eating fat can actually help burn fat. So, for anyone trying to lose weight, you may find it worth the carb cut. Beyond weight loss, recent research has found some other serious health benefits of keto that may impact your life later on. Let's take a look at what the research has to say.
Keto is not hard to follow at all. See, this is why I took my diet and nutrition into my own hands. I have PCOS and the ketogenic diet has worked wonders for me. I’m finally pregnant at the age of 32 and after 11 years of marriage because the ketogenic diet made me lose over 100 lbs and brought my insulin resistance under control. I feel better than I’ve ever felt. Sometimes doctors don’t seem to know as much as they should, or as much as they assume they do, and that’s pretty disturbing. Just like they’re still using the old school and very inaccurate BMI charts that are just pure bs. I’ll just take care of myself outside of certain situations involving illness or injury. I’m doing great on my own.
The keto lifestyle sounds daunting, but it really is not. One thing many fail to mention is the hormonal shifts that occur that regulate your appetite. Give this a little time, and you will be astounded at how easy it becomes to pass on the stuff you found addictive previously. There are many factors that influence one’s success or failure, and the key is to get the information and support you need, and to stick with it long enough to see the benefits. I fine this way of eating completely sustainable, and I’m in for life.
Finally, wait it out. Certain folks who do everything by the book and follow every bit of good advice may still get a few symptoms of the keto flu. This usually comes in the initial three weeks of entering nutritional ketosis, and things get much better very quickly. Trust that your lull will pass and your energy will increase substantially—usually within a few days.
Before the discovery of neuroplasticity, scientists believed that a damaged brain cannot regenerate. However, by improving mitochondria health, reducing inflammation, and stimulating cellular cleanup, ketogenic diets can help a damaged brain repair itself. Thus, the ketogenic diet is almost a miracle for many brain diseases that were thought of as incurable.
This diet also entails weight loss because it gets rid of excess water content in the body due to a lower amount of insulin produced. The food is broken down into simple sugars, with excess energy stored as complex sugars. The pancreas produces insulin that helps regulates sugar breakdown in the body. The body needs less sugar in switching to higher intake of fat. The liver can break down fatty acids to energy in ketogenic diets. Due to eating less carbohydrate or sugars, the production lowered. In a study, 90% of all type 2 diabetics were able to lower or completely eliminate their diabetic medication after 6 months of being on a low carbohydrate diet.
Here’s what we do know: The keto diet may be useful in treating symptoms of epilepsy, a seizure disorder. “The use of keto in treating epilepsy has the most evidence,” Angelone says. One study conducted by Johns Hopkins Medicine, for example, followed epileptic patients on the keto diet and found that 36 percent of them had a 50 percent reduction in seizures after three months on the diet, and 16 percent were seizure-free. However, experts aren't entirely sure why the keto diet has this affect, she adds.
My biggest beef with this diet is that it focuses on how much and what you can eat and less about the quality of the food you eat. A recent 2018 study found that people who focused on eating plenty of vegetables and whole foods and less on counting calories and limiting food groups, lost a significant amount of weight over the course of a year. This continues to echo the notion that the key to successful weight loss is diet QUALITY and not QUANTITY. And now, there’s research that actually supports that!
Prior to the advent of exogenous insulin for the treatment of diabetes mellitus in the 1920's, the mainstay of therapy was dietary modification. Diet recommendations in that era were aimed at controlling glycemia (actually, glycosuria) and were dramatically different from current low-fat, high-carbohydrate dietary recommendations for patients with diabetes [1,2]. For example, the Dr. Elliot Joslin Diabetic Diet in 1923 consisted of "meats, poultry, game, fish, clear soups, gelatin, eggs, butter, olive oil, coffee, tea" and contained approximately 5% of energy from carbohydrates, 20% from protein, and 75% from fat . A similar diet was advocated by Dr. Frederick Allen of the same era .
To get into and stay in ketosis, you must restrict carbs and sugar – less than 50 grams per day. This initiates your body to burn the remaining carbohydrates present, after which it moves on to stored glucose (glycogen), and finally it taps into ketones. Ketones are produced by the liver and readily used by the body for potent energy production and critical brain-related functions.
After seeing thousands of patients now for years and from personal experience, I still believe it comes down to staying away from processed foods and cooking at home whenever possible. Eating a variety of fresh fruits, vegetables, proteins, and fiber. Also, cutting out any sugary liquid calories; staying away from sodas, juices and the infamous sweet tea! Keeping stress levels under control and incorporating exercise into your routine will also be key to breaking through challenging times when you are having trouble with continued weight loss.
One reason it's hard to determine the exact health effects of diets is that it's often unclear whether any observed effects come from the diet or from a combination of other factors, like stress, environment or genetics. Still, that doesn't mean all the bold claims about the keto diet are wrong, but rather that you should approach them with a healthy degree of skepticism.
I can’t tell you how often through the years I have been asked the question, “If I lose 20 pounds, will I no longer have diabetes?” Let me answer this very clearly, there is currently no cure for diabetes. Once you have been diagnosed, you have it for life. Every day, our most brilliant researchers are busy searching for a cure though. There is good news however; you can manage your diabetes, get it under control, prevent all the complications of diabetes and live a normal, healthy life.
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.
Ketogenesis has existed as long as humans have. If you eat a very low amount of carbohydrates, you starve your brain of glucose, its main fuel source. Your body still needs fuel to function, so it taps into your reserve of ketones, which are compounds the liver creates from fat when blood insulin is low. This process is known as ketosis: It’s like when a hybrid car runs out of gas and reverts to pure electricity.
Keto changes the way your body fuels itself. When you limit carbs, your body starts to burn fat, rather than glucose, for energy. You go into ketosis — when your liver converts fatty acids into molecules called ketones, an alternative source of fuel. Learn more about keto and how it works with this beginner’s guide. Burning ketones carries all kind of benefits:
Well… what are many people on a Keto diet trying to do? Lose weight right? I would guess that prior to discovering the Keto diet many of these people were caught in the trap of low fat dieting. This lead to months or years of low fat intake and consequentially low gallbladder activity. The gallbladder wasn’t needed to digest fat and so it sat idle and stones were more likely to form. Once they made the shift to a ketogenic lifestyle and their fat consumption increased upwards of 1000%, the gallbladder kicked into high gear. If the previous period of low fat dieting had caused stone formation they are going to have to deal with flushing those stones out now while on a high fat Keto diet.
