Cyclical ketogenic diet: The Bulletproof Diet falls into this category. You eat high fat, low carb (less than 50 grams of net carbs a day) five to six days of the week. On day seven, you up your carb intake to roughly 150 grams, during what’s called a carb refeed day. Carb cycling this way helps you avoid the negative effects some people experience when they restrict carbs long term, like thyroid issues, fatigue and dry eyes.[10] [11] Full ketosis isn’t for everyone, and adding carbs such as sweet potatoes, squash, and white rice one day a week keeps your body systems that need some amount of carbs functioning properly.
This is the only way my kids will eat Brussels sprouts! It’s actually great for me because this dish is fast, easy and healthy, and it makes a lovely side. Quick-cooking Brussels sprout halves are available in the prepackaged salad aisle at the grocery store. They’re a timesaver if you can find them, but you can always just buy whole ones and slice them in half. —Teri Rasey, Cadillac, Michigan
There are three instances where there’s research to back up a ketogenic diet, including to help control type 2 diabetes, as part of epilepsy treatment, or for weight loss, says Mattinson. “In terms of diabetes, there is some promising research showing that the ketogenic diet may improve glycemic control. It may cause a reduction in A1C — a key test for diabetes that measures a person’s average blood sugar control over two to three months — something that may help you reduce medication use,” she says.

The Johns Hopkins Hospital protocol for initiating the ketogenic diet has been widely adopted.[42] It involves a consultation with the patient and their caregivers and, later, a short hospital admission.[18] Because of the risk of complications during ketogenic diet initiation, most centres begin the diet under close medical supervision in the hospital.[9]


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]
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.
Around this time, Bernarr Macfadden, an American exponent of physical culture, popularised the use of fasting to restore health. His disciple, the osteopathic physician Dr. Hugh William Conklin of Battle Creek, Michigan, began to treat his epilepsy patients by recommending fasting. Conklin conjectured that epileptic seizures were caused when a toxin, secreted from the Peyer's patches in the intestines, was discharged into the bloodstream. He recommended a fast lasting 18 to 25 days to allow this toxin to dissipate. Conklin probably treated hundreds of epilepsy patients with his "water diet" and boasted of a 90% cure rate in children, falling to 50% in adults. Later analysis of Conklin's case records showed 20% of his patients achieved freedom from seizures and 50% had some improvement.[10]
Please try reading jason fungs book that Melissa recommended, even though you are familiar with IF. I’ve only read the introduction and some from his blog as well as his posts on dietdoctor.com and it looks like sometimes if your insulin sensitivity is very damaged it could require longer fasts to get it back in check. Dr. Fung states that everything in his book is available in his blog, just that the book is a more organized way to access it but he wants everyone to have access to this life changing information. The testimonial from Jimmy Moore was eye opening where he recounted his experiences with IF

Infants and patients fed via a gastrostomy tube can also be given a ketogenic diet. Parents make up a prescribed powdered formula, such as KetoCal, into a liquid feed.[18] Gastrostomy feeding avoids any issues with palatability, and bottle-fed infants readily accept the ketogenic formula.[30] Some studies have found this liquid feed to be more efficacious and associated with lower total cholesterol than a solid ketogenic diet.[3] KetoCal is a nutritionally complete food containing milk protein and is supplemented with amino acids, fat, carbohydrate, vitamins, minerals and trace elements. It is used to administer the 4:1 ratio classic ketogenic diet in children over one year. The formula is available in both 3:1 and 4:1 ratios, either unflavoured or in an artificially sweetened vanilla flavour and is suitable for tube or oral feeding.[50] Other formula products include KetoVolve[51] and Ketonia.[52] Alternatively, a liquid ketogenic diet may be produced by combining Ross Carbohydrate Free soy formula with Microlipid and Polycose.[52]
Without peer-reviewed clinical trials, many of the benefits remain anecdotal. For instance, Weiss himself has been on a low-carb high-fat (though not strictly ketogenic) diet for more than six months, and claims he does feel much better. But he’s clear about what he knows and what he doesn’t. He’s lost weight and his borderline pre-diabetes is gone.  

You rock! Thank you for this, and would love a 7 day menu plan, plus a shopping list. I’m no good at that kind of organization – heck, I’m no good at ANY kind of organization – so a shopping list would be a life saver. I’m sure I could get that from a friend who introduced me to your blog and who is going to do this with you, and I with all of you . Thank you so much!
"My suggestion is to start with changing your mindset first and foremost around three very important facts: this is not just another diet, you don’t have to live in Ketosis forever, and you will not be depriving yourself. Having said that, if you are used to eating highly-processed sugary food and refined carbohydrates you’ll need to ease into it," she explains.
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 🤗
Thank you Mellissa. I guess I need to set up a Reddit account. Several people have directed me there for Keto forums for one reason or another. I try not to let it get me down but I have been fluctuating really badly since I started this WOE and I have a feeling it has a lot to do with the hormones not being balanced. I came off of a prepackaged, doctor recommended food plan that really knocked me outta whack and helped me discover that I do indeed have an under-active thyroid, which I have known most of my life because I have always felt hormonally off balance and could never lose weight. It is also genetic in my family but doctors never listened to me and at most would run the basic blood test to appease me which always came back normal…which is common…and when they did, they would lecture me about losing weight and hand me a prescription for diet pills or give me info on some fad diet. Now I am trying to fix it with Keto and natural remedies. I feel better than I ever have in my life on the energy front and that was almost an instant feeling after switching to Keto. I hope I balance out soon because I am 35-40 lbs down since mid-May (depending on my fluctuation for the week) and have about 100+ to go. The frustrating part is I have now lost the same 3-5 lbs repeatedly over the past 5-6 weeks and all I can think is that could have been 20-30 lbs closer to my goal weight! I even considered going back on that nasty diet even though I felt terrible because I did lose consistently. I have confirmed my macros with some others who are more experienced and they are just as boggled as I am about the bad fluctuation.

You’re very welcome, Judy! I’m glad it’s helpful. If you are keto (as opposed to low carb), unfortunately peaches would not allow you to stay in ketosis. You can check my keto food list to help determine what is keto friendly. Of course, there are worse things than fresh fruit 🙂 but in the end our bodies still see the sugar. That being said, it doesn’t mean you sabotaged the whole day. Just pick up again – you got this!! (And for next time, try some fresh berries in moderation when you’re craving fruit.)

Hey folks, I am a 55 year old guy whos used to be in good shape, so was wondering if I could use the Keto diet to lose fat and gain muscle, obviously I would have to increase caloric intake as I am weight training and performing cardio so was wondering about supplements, vits and minerals as well whey protein, as I am trying to lose body fat and build muscle I need extra calories.. plus creatine and NO pre work out and a post work supplement…

Love the set of instructions and advice; this will be what I point people at now when they want to know how to start. I avoided most “keto flu” symptoms by getting just 30 minutes a day of gentle exercise. Somewhere deep in “The Art & Science of Low Carb Living” it explains why. The Atkins books don’t mention it because their approach is to position fitness as an entirely optional thing.


Net carbs is simply total carbs minus fiber and non-digestible sugar alcohols, like erythritol. (This doesn’t apply to high glycemic sugar alcohols, like maltitol.) We don’t have to count fiber and certain sugar alcohols in net carbs, because they either don’t get broken down by our bodies, are not absorbed, or are absorbed but not metabolized. (Read more about sugar alcohols here.)
The remaining calories in the keto diet come from protein — about 1 gram (g) per kilogram of body weight, so a 140-pound woman would need about 64 g of protein total. As for carbs: “Every body is different, but most people maintain ketosis with between 20 and 50 g of net carbs per day,” says Mattinson. Total carbohydrates minus fiber equals net carbs, she explains.
