Welcome to the Keto Fit Diet. We have been in the weight loss industry for over 10 years now and have gone through every possible thread of research combined with clinical studies and our background in the healthcare industry in order to create the most successful weight loss method available. We have all struggled with getting rid of those unwanted pounds, using whatever unsuccessful means we could find. We have all tried the “miracle in a bottle” supplements, magic tricks and ridiculous diets to achieve our health and weight goals only to come up short or lose motivation before we ever see any real results. Well after 10 years of research, trial, error, and experience we have finally found the perfect, easy to use, solution to achieving our health and weight loss goals; the Keto Diet.

About 20% of children on the ketogenic diet achieve freedom from seizures, and many are able to reduce the use of anticonvulsant drugs or eliminate them altogether.[3] Commonly, at around two years on the diet, or after six months of being seizure-free, the diet may be gradually discontinued over two or three months. This is done by lowering the ketogenic ratio until urinary ketosis is no longer detected, and then lifting all calorie restrictions.[45] This timing and method of discontinuation mimics that of anticonvulsant drug therapy in children, where the child has become seizure free. When the diet is required to treat certain metabolic diseases, the duration will be longer. The total diet duration is up to the treating ketogenic diet team and parents; durations up to 12 years have been studied and found beneficial.[9]
Carol- so sorry to hear about your stroke. I am not sure most doctors would approve of this diet due to most not being taught much on nutrition in med school, and most still believe in the old school high carb low fat way of eating. My experience has been a dramatic drop in my blood pressure in only a few weeks after starting this diet (172/105 down to 144/95!). I suggest giving it a trial of a few months to see how it may work for you.

The ketogenic diet is calculated by a dietitian for each child. Age, weight, activity levels, culture and food preferences all affect the meal plan. First, the energy requirements are set at 80–90% of the recommended daily amounts (RDA) for the child's age (the high-fat diet requires less energy to process than a typical high-carbohydrate diet). Highly active children or those with muscle spasticity require more calories than this; immobile children require less. The ketogenic ratio of the diet compares the weight of fat to the combined weight of carbohydrate and protein. This is typically 4:1, but children who are younger than 18 months, older than 12 years, or who are obese may be started on a 3:1 ratio. Fat is energy-rich, with 9 kcal/g (38 kJ/g) compared to 4 kcal/g (17 kJ/g) for carbohydrate or protein, so portions on the ketogenic diet are smaller than normal. The quantity of fat in the diet can be calculated from the overall energy requirements and the chosen ketogenic ratio. Next, the protein levels are set to allow for growth and body maintenance, and are around 1 g protein for each kg of body weight. Lastly, the amount of carbohydrate is set according to what allowance is left while maintaining the chosen ratio. Any carbohydrate in medications or supplements must be subtracted from this allowance. The total daily amount of fat, protein and carbohydrate is then evenly divided across the meals.[36]
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.
Because it lacks carbohydrates, a ketogenic diet is rich in proteins and fats. It typically includes plenty of meats, eggs, processed meats, sausages, cheeses, fish, nuts, butter, oils, seeds, and fibrous vegetables. Because it is so restrictive, it is really hard to follow over the long run. Carbohydrates normally account for at least 50% of the typical American diet. One of the main criticisms of this diet is that many people tend to eat too much protein and poor-quality fats from processed foods, with very few fruits and vegetables. Patients with kidney disease need to be cautious because this diet could worsen their condition. Additionally, some patients may feel a little tired in the beginning, while some may have bad breath, nausea, vomiting, constipation, and sleep problems.
Chasing blood Ketones instead of focusing on hormone signals: "The higher the number means you have more Ketones circulating in your bloodstream, but that does not mean that you are better at burning fat for fuel," Mavridis points out. "You must be in nutritional Ketosis, which is described as being between 1.5 - 3.0 mol/L on the blood Ketone meter. You will know once you are fat-adapted from hormonal signals, and not from higher Ketones on the blood meter," she adds.
Josh Axe, a doctor of natural medicine and clinical nutritionist, estimates that about 25% of people who try a ketogenic diet experience these symptoms, with fatigue being the most common. “That happens because your body runs out of sugar to burn for energy, and it has to start using fat,” he says. “That transition alone is enough to make your body feel tired for a few days.”
I love this! I am an amateur powerlifter and I have recently started using the keto diet as there is only so much gained by being a fat powerlifter but working out my macros was driving me nuts as I also work as a disability support worker and need to take meals and so on to work with me. Thanks to this I can now have better control of the macros to bring my weight down without doing to much harm to my lifts! Thank you for this!

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 low glycaemic index treatment (LGIT)[48] is an attempt to achieve the stable blood glucose levels seen in children on the classic ketogenic diet while using a much less restrictive regimen. The hypothesis is that stable blood glucose may be one of the mechanisms of action involved in the ketogenic diet,[9] which occurs because the absorption of the limited carbohydrates is slowed by the high fat content.[5] Although it is also a high-fat diet (with approximately 60% calories from fat),[5] the LGIT allows more carbohydrate than either the classic ketogenic diet or the modified Atkins diet, approximately 40–60 g per day.[3] However, the types of carbohydrates consumed are restricted to those that have a glycaemic index lower than 50. Like the modified Atkins diet, the LGIT is initiated and maintained at outpatient clinics and does not require precise weighing of food or intensive dietitian support. Both are offered at most centres that run ketogenic diet programmes, and in some centres they are often the primary dietary therapy for adolescents.[9]
Bottom line: If you don't measure and calculate exactly each food and ingredient, you won't be able to get into ketosis or maintain it. And who wants to be sitting around measuring and counting everything? Again, this diet really takes the enjoyment out of cooking and eating.

If you have been looking for a weight loss plan, however, you've probably heard of one of the ketogenic diet’s biggest claims to fame: the quick results it supposedly produces. Some people report losing as much as 10 pounds in the first two weeks. But this weight loss is likely to be mostly water weight, not fat melting away, meaning you stand to gain it back once you replenish fluids. The ketogenic diet can act as a diuretic, causing water loss from glycogen storage in the liver, muscles, and fat cells. Keep in mind that for most people, about ½ pound to 2 pounds per week is considered safe.
Other kinesiologists think the keto diet could have dangerous effects on athletic performance, and it's tough to know what potential side effects a long-term high-fat diet might have for a healthy person, since we don't have any solid study results yet. Low-carb diets like keto can make it easy to neglect key nutrients like magnesium, calcium, and potassium found in fresh, high-carb foods like beans, bananas, and oats.
Normal dietary fat contains mostly long-chain triglycerides (LCT). Medium-chain triglycerides are more ketogenic than LCTs because they generate more ketones per unit of energy when metabolised. Their use allows for a diet with a lower proportion of fat and a greater proportion of protein and carbohydrate,[3] leading to more food choices and larger portion sizes.[4] The original MCT diet developed by Peter Huttenlocher in the 1970s derived 60% of its calories from MCT oil.[15] Consuming that quantity of MCT oil caused abdominal cramps, diarrhoea and vomiting in some children. A figure of 45% is regarded as a balance between achieving good ketosis and minimising gastrointestinal complaints. The classical and modified MCT ketogenic diets are equally effective and differences in tolerability are not statistically significant.[9] The MCT diet is less popular in the United States; MCT oil is more expensive than other dietary fats and is not covered by insurance companies.[3]
The day before admission to hospital, the proportion of carbohydrate in the diet may be decreased and the patient begins fasting after his or her evening meal.[18] On admission, only calorie- and caffeine-free fluids[36] are allowed until dinner, which consists of "eggnog"[Note 8] restricted to one-third of the typical calories for a meal. The following breakfast and lunch are similar, and on the second day, the "eggnog" dinner is increased to two-thirds of a typical meal's caloric content. By the third day, dinner contains the full calorie quota and is a standard ketogenic meal (not "eggnog"). After a ketogenic breakfast on the fourth day, the patient is discharged. Where possible, the patient's current medicines are changed to carbohydrate-free formulations.[18]

“Brain fog” is a common complaint among people on extremely low-carb diets like keto. “I remember one client in particular who had been put on a keto diet for her PCOS [polycystic ovary syndrome] who kept telling me how much better she felt after eating in a more balanced, more nourishing way for a couple of weeks at our program,” Notte says. Make sure you know these 15 things before starting the keto diet.

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:
Short-term results for the LGIT indicate that at one month approximately half of the patients experience a greater than 50% reduction in seizure frequency, with overall figures approaching that of the ketogenic diet. The data (coming from one centre's experience with 76 children up to the year 2009) also indicate fewer side effects than the ketogenic diet and that it is better tolerated, with more palatable meals.[3][49]

The ketogenic diet has been studied in at least 14 rodent animal models of seizures. It is protective in many of these models and has a different protection profile than any known anticonvulsant. Conversely, fenofibrate, not used clinically as an antiepileptic, exhibits experimental anticonvulsant properties in adult rats comparable to the ketogenic diet.[57] This, together with studies showing its efficacy in patients who have failed to achieve seizure control on half a dozen drugs, suggests a unique mechanism of action.[55]
There is nothing inherently difficult about following a ketogenic diet. We have many patients who do this very easily over many years. The metabolic benefits significantly outway any perceived challenges from limiting particular food types. Uptake would be far more widespread if nutrition professionals left their predujical opinions of SFA’s behind. Finally, given the expertise in Ketogenic Diets at Harvard, Dr David Ludwig, for one springs to mind, I am surprised the author did not avail themselves of the local expertise.
The gist of the eating plan? Taking in so few carbs sends your body into ketosis—a state of burning fat for energy, instead of carbohydrates or sugars, explains Beth Warren, RDN, founder of Beth Warren Nutrition and author of Secrets of a Kosher Girl: A 21-Day Nourishing Plan to Lose Weight and Feel Great (Even If You're Not Jewish). In order to stay in ketosis, you only consume 5% to 10% of your calories from carbohydrates—which for most followers is fewer than 20 grams total per day—and instead eat moderate amounts of protein and high amounts of fat.

Positive science on ketosis coupled with personal successes passed by word-of-mouth have driven more people to explore the ketogenic diet, says Volek. More recently, the keto diet hints at having a promising therapeutic role in cancer, Alzheimer’s, Parkinson’s and polycystic ovary syndrome (PCOS). Research is still early in many areas, but Volek suspects there will more definitive answers on the wider scope of the diet’s benefits within the next decade.


The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet that in medicine is used primarily to treat difficult-to-control (refractory) epilepsy in children. The diet forces the body to burn fats rather than carbohydrates. Normally, the carbohydrates contained in food are converted into glucose, which is then transported around the body and is particularly important in fueling brain function. However, if there is little carbohydrate in the diet, the liver converts fat into fatty acids and ketone bodies. The ketone bodies pass into the brain and replace glucose as an energy source. An elevated level of ketone bodies in the blood, a state known as ketosis, leads to a reduction in the frequency of epileptic seizures.[1] Almost half of children and young people with epilepsy who have tried some form of this diet saw the number of seizures drop by at least half, and the effect persists even after discontinuing the diet.[2] There is some evidence that adults with epilepsy may benefit from the diet, and that a less strict regimen, such as a modified Atkins diet, is similarly effective.[1] The most common adverse effect is constipation, affecting about 30% of patients—this was due to fluid restriction, which was once a feature of the diet, but this led to increased risk of kidney stones and is no longer considered beneficial.[2][3]
The ketogenic diet has been studied in at least 14 rodent animal models of seizures. It is protective in many of these models and has a different protection profile than any known anticonvulsant. Conversely, fenofibrate, not used clinically as an antiepileptic, exhibits experimental anticonvulsant properties in adult rats comparable to the ketogenic diet.[57] This, together with studies showing its efficacy in patients who have failed to achieve seizure control on half a dozen drugs, suggests a unique mechanism of action.[55]
A systematic review in 2018 looked at sixteen studies on the ketogenic diet in adults. It concluded that the treatment was becoming more popular for that group of patients, that the efficacy in adults was similar to children, the side effects relatively mild. However, many patients gave up with the diet, for various reasons, and the quality of evidence inferior to studies on children. Health issues include high levels of low-density lipoprotein (LDL), high total cholesterol, and weight loss.[23]
If you’re a newbie planning your weekly keto diet plan, make the meals as easy as possible. A keto breakfast, for example, can take advantage of many classic breakfast foods, including eggs, bacon, sausage, and ham. Eggs are real winners in the keto world. They’re extremely versatile, easy to cook, and have just half a gram of carbs but 6 g of protein and 5 g of fat.
One of the most common side effects of starting the ketogenic diet is the “keto flu.” This term describes the often unpleasant, fatigue-inducing symptoms that occur as the body adjusts from a high-carbohydrate to a low-carbohydrate diet. During the keto flu, the body’s stored glucose begins depleting, and the body starts adapting to producing and utilizing ketones as energy. (2)

“When you’re on a restrictive diet, deprivation builds and builds, and when you finally give in and have something that’s not on your plan, you can overeat,” Notte says. This can lead to shame and guilt, she warns. “You think, well, I already blew it, so I might as well just eat it all,”  she says. Occasional binge eating can, in turn, develop into a full-blown disorder called binge eating disorder for those who are predisposed to it, according to the National Eating Disorders Association. Check out the 10 surprising health benefits of keto.
The classic ketogenic diet is not a balanced diet and only contains tiny portions of fresh fruit and vegetables, fortified cereals and calcium-rich foods. In particular, the B vitamins, calcium and vitamin D must be artificially supplemented. This is achieved by taking two sugar-free supplements designed for the patient's age: a multivitamin with minerals and calcium with vitamin D.[3] A typical day of food for a child on a 4:1 ratio, 1,500 kcal (6,300 kJ) ketogenic diet comprises:[27]

On a ketogenic diet, you’re generally eating a diet that’s high in fat (roughly 70 percent of your total calories come from fat), moderate in protein (about 20 percent of your calories), and low in carbohydrate (about 5 percent of calories). By limiting carbohydrates (to usually less than 45 grams for the average person), your body lacks the glucose (from carbs) that it normally uses for energy, so it eventually switches over to burning fat as its primary fuel source instead; through a metabolic process called ketosis, the liver converts the fat into fragments of fatty acids called ketones, which power the brain and other organs and tissues.


Another reason for the quick weight loss when you start a keto plan is water loss. “Nitrogen is one by-product of breaking down protein for fuel,” says Notte. “Free nitrogen floating around the body is toxic, so the body flushes it out with frequent urination.” This loss of fluids shows up as pounds lost on the scale. But it can also lead to dehydration and an imbalance of electrolytes—the minerals and salts your muscles rely upon. This is why some keto dieters get terrible leg cramps, Notte explains. “The same thing happens with the Atkins diet—keto is just today’s version.” Make sure you know what happens to your body on keto.

To get the most benefit from the Keto diet, you should stay physically active. You might need to take it easier during the early ketosis period, especially if you feel fatigued or lightheaded. Walking, running, doing aerobics, weightlifting, training with kettlebells or whatever workout you prefer will boost your energy further. You can find books and online resources on how to adapt Keto meals or snacks for athletic training.
