You can have a completely smooth transition into ketosis, or…not. While your body is adapting to using ketones as your new fuel source, you may experience a range of uncomfortable short-term symptoms. These symptoms are referred to as “the keto flu.” Low-sodium levels are often to blame for symptoms keto flu, since the kidneys secrete more sodium when you’re in ketosis, says Volek. A few side effects:

H. Guldbrand, B. Dizdar, B. Bunjaku, T. Lindström, M. Bachrach-Lindström, M. Fredrikson, C. J. Östgren, F. H. Nystrom, “In Type 2 Diabetes, Randomisation to Advice to Follow a Low-carbohydrate Diet Transiently Improves Glycaemic Control Compared with Advice to Follow a Low-fat Diet Producing a Similar Weight Loss,” Diabetologia (2012) 55: 2118. http://link.springer.com/article/10.1007/s00125-012-2567-4.
Early studies reported high success rates: in one study in 1925, 60% of patients became seizure-free, and another 35% of patients had a 50% reduction in seizure frequency. These studies generally examined a cohort of patients recently treated by the physician (what is known as a retrospective study) and selected patients who had successfully maintained the dietary restrictions. However, these studies are difficult to compare to modern trials. One reason is that these older trials suffered from selection bias, as they excluded patients who were unable to start or maintain the diet and thereby selected from patients who would generate better results. In an attempt to control for this bias, modern study design prefers a prospective cohort (the patients in the study are chosen before therapy begins) in which the results are presented for all patients regardless of whether they started or completed the treatment (known as intent-to-treat analysis).[18]
This means that if you have risk factors for heart disease — such as elevated cholesterol levels, high blood pressure (hypertension), or a strong family history of the disease — you should use caution when following this diet. The diet's heavy reliance on fat, especially saturated fat, can elevate cholesterol levels, further increasing your chances of developing heart disease in the future. (7)
The keto diet does provide short-term benefits, but the long-term benefits are still unknown. Researchers caution that a very low  carb diet can be difficult to maintain long term, leading to “yo-yo” dieting and increased weight gain. Researchers suggest that the keto diet can be used to kick start weight loss, but should be followed up with healthy eating plans that can be sustained long term.

For people with diabetes, rapidly rising ketone levels can signal a health crisis that requires immediate medical attention. When there is an absence or not enough of the hormone insulin (or the body is too resistant to insulin to allow it to drive glucose into the cells for energy), the body cannot use glucose for fuel. Insulin helps ferry glucose to our cells and muscles for energy. Instead, in this case, the body resorts to burning stored fat for energy through the process of ketosis, leading to a buildup of ketones in the body.

Inducing ketosis – a natural state for the body, when it is almost completely fuelled by fat – in therapeutic diets is a skill that needs the close supervision of a dietitian in a specialist clinic. This is because the diet is not balanced and can easily lead to nutrient deficiencies, nausea, vomiting, headache, tiredness, dizziness, insomnia, poor exercise tolerance and constipation – sometimes referred to as keto flu.


Hi. Loved the article. I ran across this article when I found your pancake recipe. I am going on a cruise in 18 days. I started eating a high cal low carb diet a couple of days ago and noticed how similar it was to the Keto diet. So I said why not since I’m already kind of doing that. Then, I saw that you mentioned unusual periods and I am extremely worried that if I start the keto diet today, I might have my period while on my cruise and that is not going to be fun. What are your thoughts?
The ketone bodies are possibly anticonvulsant; in animal models, acetoacetate and acetone protect against seizures. The ketogenic diet results in adaptive changes to brain energy metabolism that increase the energy reserves; ketone bodies are a more efficient fuel than glucose, and the number of mitochondria is increased. This may help the neurons to remain stable in the face of increased energy demand during a seizure, and may confer a neuroprotective effect.[55]
If you’ve decided to move forward in trying the keto diet, you will want to stick to the parameters of the eating plan. Roughly 60 to 80 percent of your calories will come from fats. That means you’ll eat meats, fats, and oils, and a very limited amount of nonstarchy vegetables, she says. (This is different from a traditional low-carb diet, as even fewer carbs are allowed on the keto diet.)
A low carb diet plan is a way of eating that is high in fat, moderate in protein and low in carbohydrates. There are different variations of low carb, and the keto diet is a special type of low carb with added characteristics. The number of carbohydrates will vary depending on your insulin tolerance and activity level, but on average, these are the common numbers of carbs:
First, I want to thank you for all of your dedication and work in providing this site. The difficulty of maintaining a healthy weight is a big problem for so many people. My personal question & issue in staying on Keto is my craving for fresh fruit. This a.m I had a large fresh peach along with my “Bullet Proof” coffee. Have I now sabotaged today’s Keto eating?
Those issues can be part of what's known as the “keto flu,” Warren says. Other side effects of the keto diet, all of which are tied to carb withdrawal, can include lightheadedness, nausea, mental fog, cramps, and headaches, in addition to tiredness. Luckily, the keto flu doesn't usually last more than a week—which is coincidentally about when people start to see the number on the scale go down, says Warren.
A typical day on a keto diet might include breakfast of fried eggs or a frittata with eggs, mushrooms, cheese and butter; lunch of chicken thighs with cabbage and olive oil; and dinner of bacon burgers with green beans and butter. The emphasis on proteins and fats also is intended to provide a feeling of fullness, which can make the eating plan easier to stick to.
I am a type 1 diabetic of 57 years. I am my doctor’s only patient that has had this disease this long with no diabetic problems. My A1C average is 7.0. My experience with eating a Keto diet is my blood glucose goes very high when eating more fat. I got no help from doctor, so I learned by trial and error to take more insulin for the among of fat I eat. I have it down to a percentage. If eating 6 carbs for breakfast and 18g of fat, I divide 30% into the 18g of fat, which will be 6. I add the 6 with the 6 carbs and I take 12 units of insulin for my breakfast. Not only do we need to take insulin for the carbs we eat, but also for the fat when eating the amount you should consume on a Keto diet. I have been using My Fitness Pal for 9 years to document everything I eat, keeping up with the total calories, carbs, fat, sodium, protein and sugar.

Anticonvulsants suppress epileptic seizures, but they neither cure nor prevent the development of seizure susceptibility. The development of epilepsy (epileptogenesis) is a process that is poorly understood. A few anticonvulsants (valproate, levetiracetam and benzodiazepines) have shown antiepileptogenic properties in animal models of epileptogenesis. However, no anticonvulsant has ever achieved this in a clinical trial in humans. The ketogenic diet has been found to have antiepileptogenic properties in rats.[55]


Hello wanting to start this Keto diet asap. I have a quick question. I’m addicted to pop. Yes I’ve tried switching to tea and coffee. When I go one day without any pop I take a bad migraine. Its crippling I am in bed throwing up and movement sound lights everything makes it worse. The only way to get over them is by consuming a soda. I have talked to my Doctor she is no help at all. I don’t believe she has ever suffered from a migraine. I know my body will detox and I will get over it. Problem is I am a single mom of 3 young kids. Whom cant take care of them selves. I’m not sure how to kick the soda habit without leaving me begging for death for the next week. Any ideas how I can get threw this. Ive tried most otc meds.
This reminds me …… just after WWll, when there wasn’t a lot of meat available let alone any *special* foods to enjoy, my MoM used to cook up strips of bacon, then make creamed Mushrooms and supper would be bacon and creamed mushrooms on toast ….. ummmm it was so good! Your recipe not only brought back a memory but has also spurned me to make myself some bacon with creamed mushrooms on toast for my dinner tomorrow night 🤗

This low-carb chicken pad thai is one of the best keto recipes for replacing Asian takeout.

Best of all, you’ll have this keto chicken recipe on the table in just 30 minutes.
You may have heard by now that I finally wrote and published a “real” book called Keto for Life!!!  The reviews are in and people are loving it!  Already a best seller, you can learn more about what you’ll find inside Keto for Life by clicking here!  OR head over to Amazon to check out the reviews of Keto for Life before snagging a copy for yourself!
A lot of people take their macros as a “set in stone” type of thing. You shouldn’t worry about hitting the mark every single day to the dot. If you’re a few calories over some days, a few calories under on others – it’s fine. Everything will even itself out in the end. It’s all about a long term plan that can work for you, and not the other way around.
Beyond just fat loss, ketosis has an additional benefit in that it spares muscle when you’re eating at a deficit. On a normal diet, when you eat fewer calories than you need for the day, your body breaks down muscle and fat in nearly equal amounts to make up for the difference. With keto, your body is primed to burn mostly fat, particularly if you’re meeting your protein goal for the day. This results in a better metabolism and more total fat lost. Low carb recipes offer:
People claiming huge benefits of these supplements – despite the lack of solid scientific support – may sometimes have a financial reason to believe in the supplements. Some of these products are sold under a multi-level marketing arrangement, where sales people are paid based on commission. For example, the company Prüvit sells drinkable ketones, called KETO//OS with a multi-level marketing structure.
