If you want to use a ketogenic diet as a health tool, it would be wise to do so for no more than a few weeks at a time, as nobody knows how long is too long. And, of course, the period of time during which ketosis is safe can vary from individual to individual. Breaking ketosis is as easy as upping protein intake or having a glass of wine or whole piece of fruit.
The main limitations of our study are its small sample size, short duration, and lack of control group. That the main outcome, hemoglobin A1c, improved significantly despite the small sample size and short duration of follow-up speaks to the dramatic and consistent effect of the LCKD on glycemia. For other effects, however, such as the rises in serum LDL and HDL cholesterol, the small sample size might be the reason statistical significance was not reached. Future studies of larger samples and containing a control group are needed to better address questions about the effect of the LCKD on serum lipids in patients with type 2 diabetes.
Resistant starches can be included as part of a ketogenic diet or as a supplement because it has minimal effects on blood sugar, so it doesn’t disrupt the state of ketosis. Resistant starches not only feed good bacteria in the gut but can also get fermented into substances that are beneficial for health. (Read this post to learn more about the health benefits of resistant starches and how to use them.)
Does the Swank diet help with multiple sclerosis? The Swank diet is a low-fat diet based on findings of a study into the prevalence of multiple sclerosis (MS) in different regions, starting from the 1940s. Fruit, vegetables, and fish are recommended and supplements may be encouraged. While it may help, there are concerns that the diet is too restrictive. Read now

Thank you for this comment. It is truth! I keep telling people about this diet. It is literally the best diet I have ever been on. I can eat good food, I feel full, my weight is dropping, I feel better and I can actually feel the difference. While it is great for a professional to be skeptical of emerging diet trends (and lets face it, most diet trends are garbage peddled by snake oil salesmen), this one actually has science from some prestigious institutions behind it, not a marketing scheme.
If you are seeking fat loss but do not want to follow a strict ketogenic diet, you will be pleased to know that this study found that the weight loss benefits came purely from a low carb diet – whether it was ketogenic or not. If you need help transiting to a lower carb diet, be sure to download my free diet plan or better yet, be sure to view the most effective way to lose fat and keep it off on this page. 
In the mid-1990s, Hollywood producer Jim Abrahams, whose son's severe epilepsy was effectively controlled by the diet, created the Charlie Foundation to promote it. Publicity included an appearance on NBC's Dateline programme and ...First Do No Harm (1997), a made-for-television film starring Meryl Streep. The foundation sponsored a multicentre research study, the results of which—announced in 1996—marked the beginning of renewed scientific interest in the diet.[1]

A ketogenic diet is very low in carbs, high in fat and moderate in protein. For a weight stable person, no more than 5% of calories should come from carbs, 70-80% from fat and 20-30% from protein. With this macronutrient-distribution, individuals do not rely on glucose as a major source of energy but use fat for fuel instead. Fat is used to produce ketone bodies, which are used for energy or to regulate certain genes. Two ketone bodies circulate in in your blood: Acetoacetate (AcAc) and Beta-hydroxybutyrate (BHB). A third ketone, acetone, is spontaneously created from Acetoacetate. It is not a source of energy but is useful for ketone measurement. Check our ketone measurement guide to learn more.
Coal, on the other hand, burns evenly, and continues to burn for hours. Not only that, but it is fairly simple to adjust the amount of coal you burn to keep the house nice and warm, but not hot, for extended periods of time. The only problem is, it is kind of a hassle to get it to start burning at first (again, in the analogy we are assuming you are simply trying to light bare coal on fire, no aids). But once it is started, maintaining it is no sweat. So what is the solution? You use a tiny bit of kerosene, which lights easy and burns hot, to get the coals started (we need a few carbs, but not much).

The level of total cholesterol showed a significant decrease from week 1 to week 24 (Figure 3). The level of HDL cholesterol significantly increased (Figure 4), whereas LDL cholesterol levels significantly decreased with treatment (Figure 5). The level of triglycerides decreased significantly after 24 weeks of treatment. The initial level of triglycerides was 2.75±0.23 mmol/L, whereas at week 24, the level decreased to 1.09±0.08 mmol/L (Figure 6). The level of blood glucose significantly decreased at week 24. The initial blood glucose level and its level at the eighth, 16th and 24th week were 7.26±0.38 mmol/L, 5.86±0.27 mmol/L, 5.56±0.19 mmol/L and 5.62±0.18 mmol/L, respectively (Figure 7). The changes in the levels of urea (Figure 8) and creatinine (Figure 9) were not statistically significant.


Researchers are divided over whether the keto diet is good for people who don’t need to follow it for medical reasons. Since it doesn’t differentiate between saturated and unsaturated fats, dieters are at risk of raising their cholesterol levels. And because the heavily restrictive diet cuts out most fruits and vegetables, it can also lead to nutrient deficiency. The Harvard Health Letter warned that with so much fat and protein to metabolize, keto practitioners may experience liver and kidney problems as well.  
Here’s the thing, the Keto diet can be executed in many different ways.  The only requirement for achieving ketosis is to restrict carbs and limit protein so that the bodies glycogen reserves are depleted to the point that ketosis kicks in.  If you do that by eating hot dogs and margarine then I agree with this claim, you are on a dangerous nutrient-deficient diet.  However, if one chooses to achieve ketosis by eating fatty cuts of quality meat, dairy, nuts and plenty green leaves and fibrous vegetables-they are on a nutrient dense, complete diet.
In another study looking at ketogenic diets as a treatment for cancer,5 this research team concluded, “based on the results of rigorous preclinical and clinical studies performed thus far, the KD would appear to be a promising and powerful option for adjuvant therapy for a range of cancers. Cancer-specific recommendations await the findings of randomized controlled clinical trials.”

It’s not a good idea to include a lot of dairy in a ketogenic diet because the protein in dairy can deactivate Sirtuin, the anti-aging pathway, and create an insulin spike. While butter and ghee (from quality pastured sources) generally don’t cause this effect, high-fat cheeses and heavy creams do. In addition, dairy products can be inflammatory for many people.
“Your liver produces ketones all the time, but the rate depends on carbohydrate and protein intake,” says Jeff Volek, Ph.D., R.D., a professor of human sciences at Ohio State University. When the majority of your diet is made up of of carbs and protein, ketogenesis slows. Replacing carbs and protein with fat will put your body into ketosis, thus ramping up ketone production. This takes about three days to induce.

I can buy clothes off the rack. Better than being obese. My brain is sharper. I get more stuff done. I don’t sit around. I feel like I can feel the fat melting off. I have trouble sometimes eating enough. After 40 years if being very obese on and off, I think I am better off. I hope to use it when I need it after I reach my goal. The blood tests will prove it.


Depending on how you choose your fats, the keto diet can contain an abundance of saturated fat, which raises levels of dangerous LDL cholesterol and causes atherosclerosis, the buildup of fats and cholesterol in the arteries. If you decide to go keto, have a doctor monitor your cholesterol levels monthly to ensure you remain within a healthy range.
Now, I know what you are going to say, “I can take a break from the diet anytime.” What do you think happens when you take that “break”? As soon as you start consuming a normal amount of carbohydrates again, you immediately go out of ketosis or the fat burning state, and your body starts storing fat again immediately. In other words, you immediately start gaining weight. So whatever weight you lost on the diet, you gain back right away. How healthy do you think it is for your body to be in a starvation mode, then in a feeding frenzy, making up for lost time?
The whole area of calcium supplementation is rife with misinformation. Mainstream docs assume that osteoporosis is due solely to lack of calcium, ignoring that you need to have adequate Vit D levels to absorb the calcium in the first place (and their idea of adequate D blood levels are absurdly low) as well as Vit K2. Since bone is made of calcium phosphate, you also need adequate phosphate as well. Milk contains calcium phosphate – no surprise since it is designed to build the bones of the growing animal – so dairy is your best source of calcium. You also need protein since bone is calcium phosphate within a protein matrix. To rebuild osteoporotic bone you need 1.2gm/Kg of body weight, 50% more than the RDA of 0.8gm/Kg.
And while some fats can be healthy, there’s a risk that in following a high-fat diet, you’ll increase your intake of unhealthy trans and saturated fats. These “bad” fats are found in things like red meat, poultry skin, cheese, and butter, and can lead to an increase in LDL, or “bad” cholesterol and increased risk of heart disease. (14) This is a controversial issue, as some experts do recommend adopting a low-carbohydrate diet to lower heart disease risk. If you’re at risk or have heart disease, it’s important to speak with your doctor first about your health needs.

Yes!! Edward!! I am pre-diabetic myself and have IBS which many doctors have no explanation for many of my questions because IBS triggers everyone differently and with different foods. I have been keto for 6 weeks and have lost 14lbs and have not noticed any symptoms of IBS even when I eat trigger foods (onion/garlic) I am no means 100% keto yet because I have had slip ups here and there but I jump right back in. I can’t imagine not following this way of life moving forward. I immediately feel the difference if I indulge in anything more then I should. Im learning to listen to my body and now see carbs/sugar is what has been causing madness on my body. Keto-on Edward!
Vegan ketogenic diet or vegetarian diet: Yes, both are possible. Instead of animal products, plenty of low-carb, nutrient-dense vegan and/or vegetarian foods are included. Nuts, seeds, low-carb fruits and veggies, leafy greens, healthy fats and fermented foods are all excellent choices on a plant-based keto diet. There’s also a similar plan called ketotarian, which combines keto with vegetarian, vegan and/or pescatarian diets for supposedly greater health benefits.

In a study of 51 obese people using an extremely low fat low calorie diet (just one gram of fat a day!) the gallbladder was examined by ultrasound before the diet and after one and two months. After one month four of the 51 participants had developed new gallstones. After two months more than one in four (13 people) had new gallstones! This on an almost fat free diet. Three participants needed to have their gallbladder removed during the study.

Our bodies are incredibly adaptive to what you put into it – when you overload it with fats and take away carbohydrates, it will begin to burn ketones as the primary energy source. Optimal ketone levels offer many health, weight loss, physical and mental performance benefits.1There are scientifically-backed studies that show the advantage of a low-carb, ketogenic diet over a low-fat diet. One meta-analysis of low-carbohydrate diets showed a large advantage in weight loss. The New England Journal of Medicine study resulted in almost double the weight loss in a long-term study on ketone inducing diets.
The bottom line? If you’re thinking about trying the ketogenic diet, run it by your doctor first — regardless of any preexisting health conditions. And consult a registered dietitian nutritionist (find one at EatRight.org) to find a nutrition professional who can work with you to create a meal plan you can stick to. People with kidney disease or a history of disordered eating should avoid the diet, and people with type 1 diabetes may want to avoid it, as well. If you have risk factors for heart disease, you’ll want to speak with your doctor before considering the diet.
The data presented in the present study showed that a ketogenic diet acted as a natural therapy for weight reduction in obese patients. This is a unique study monitoring the effect of a ketogenic diet for 24 weeks. There was a significant decrease in the level of triglycerides, total cholesterol, LDL cholesterol and glucose, and a significant increase in the level of HDL cholesterol in the patients. The side effects of drugs commonly used for the reduction of body weight in such patients were not observed in patients who were on the ketogenic diet. Therefore, these results indicate that the administration of a ketogenic diet for a relatively long period of time is safe. Further studies elucidating the molecular mechanisms of a ketogenic diet are in progress in our laboratory. These studies will open new avenues into the potential therapeutic uses of a ketogenic diet and ketone bodies.
To ensure you are getting enough potassium, include avocados and leafy greens like spinach in your daily diet. Sprinkle some unrefined salt on every meal and in your water to replenish your sodium levels as well. Some ketogenic dieters suggest getting at least 5 to 7 grams of salt per day (one teaspoon to a teaspoon and a half per day) during your first week on the ketogenic diet.
Consider Using Exogenous Ketones:  Providing pre-formed ketones takes stress off of the body and improves the bodies ability to use ketones as a fuel sources.  This, in turn, improves the bodies ability to make its own ketones and speeds up the keto adaptation process.  The best is when you take exogenous ketones with adaptogens which help stabilize blood sugar, improve the stress response and support your brain.  I recommend Keto Edge as the best all round exogenous ketone, adaptogen mix.
And, it's important to recognize that both study teams acknowledge that as exciting as their findings seem, a large, randomized controlled trial is still needed to more closely assess a variety of components that may be contributing to the successes found in both studies before the findings can be recommended to anyone outside the study groups1,2  he says.
Controlling your blood sugar levels helps you control your cravings, Dr. Burrows says. “When we are not on a sugar roller coaster from processed carbohydrates, most people make better food choices because they are not looking for their next hit of food,” she says. You may also find you’re able to go longer periods without eating, he says. Intermittent fasting is a common practice among dieters who’ve been eating keto for a while. Learn how one woman totally kicked her sugar habit by trying the keto diet.
A ketogenic diet – due to its extremely low carb intake – can help address insulin resistance and in turn help with suffers of PCOS. In fact, a pilot study has concluded that a ketogenic diet led to a significant improvement in body weight, fasting insulin, testosterone markets and LH/FSH ratio in woman with PCOS. Two woman even became pregnant during the study.

Type 1 diabetes causes the same blood sugar control issues as type 2 diabetes, but in an entirely different way. Type 1 diabetics cannot produce enough insulin or any insulin at all, which requires them to have insulin administered exogenously. On top of that, the perfect diet will not be able to reverse this disease as the ketogenic diet can for type 2 diabetes.
Originally developed in 1924 to treat epilepsy, the ketogenic diet has most recently rose in popularity as the latest and greatest miracle weight-loss plan. Additionally, proponents of the ketogenic diet—or keto diet, as it’s commonly known—advertise health benefits ranging from glucose control to treatment of Alzheimer’s. But, what does the research really show?
Fanatic? Someone with T2D, a disease usually claimed to be progressive and a never ending stream of problems and medications, was REVERSED. That’s something to shout from the rooftops. The drop in medication use alone, but the big pharma companies would prefer that people’s stories of reversing (well, putting it into remission) T2D get called fanatical instead of insightful.

The high-fat intake required for ketosis may change the structure of LDL ("bad") cholesterol and lipoproteins, which could induce inflammation over time. Chronic inflammation is a biological state in which your body's cells work overtime to get their regular job done. Healthcare professionals can ID inflammation through blood work by looking for signs of oxidative stress (a.k.a. the damage done by free radicals to organ tissues).


Work towards cycling fasting days so you’re fasting on 2–3 nonconsecutive days per week (e.g. Tuesday, Thursday and Saturday). Stick to only light exercise or yoga on fasting days to reduce feeling exhausted or hungry, keeping higher intensity activities for your non-fasting days. This approach allows for more dietary and lifestyle “moderation” because the goal isn’t to eat 100 percent “perfectly” all the time.
