But first a little legal and medical coverage: Although I have a Master's degree in Applied Clinical Nutrition, I am not a physician. I do have extensive experience with eating the ketogenic way, and I cured my health problems with a ketogenic diet. I am not guaranteeing that this diet will work for you or cure your health problems. I am just sharing what I know about ketogenic diets. Click here for the full legal disclaimer.
In the worst form of diabetes (type 1), a condition called ketoacidosis can exist. This is completely different from ketosis. Ketoacidosis is a disease state where there is no more insulin and acids build up to high levels that are dangerous to one's health. But with ketosis, the pH in the body doesn't even get close to the high levels seen with ketoacidosis.
Keep up electrolytes. The major electrolytes in our bodies are sodium, potassium and magnesium. Because a low carb diet (especially a keto diet!) reduces the amount of water you store, this can flush out electrolytes and make you feel sick (called “keto flu”). This is temporary, but you can avoid or eliminate it by salting your food liberally, drinking broth (especially bone broth), and eating pickled vegetables. Some people also choose to take supplements for electrolytes, but it’s best to first consult a doctor that understands and supports keto/low carb lifestyles.
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.”
So people saying that – despite the lack of scientific support – likely have a financial reason to say it. Some of these products are sold under something like a multi-level marketing arrangement, so sales people are entirely paid based on commission. For example, the company Prüvit sells drinkable ketones, called KETO//OS with a multi-level marketing structure.
These cookies will definitely satisfy your sweet tooth while keeping you in ketosis, says Fillenworth. They're made primarily with coconut and cashews, which are rich in good fats. Although they contain some coconut sugar, these cookies get most of their keto-safe chocolate flavor from unsweetened chocolate. However, Fillenworth notes that a serving of two cookies contains 8 grams of net carbs, which can be too high for some keto dieters. She recommends sticking with one cookie if you want to successfully work it into your diet. (Also try these homemade keto fat bombs for a sweet treat.)
Note that the U.S. Department of Agriculture advises against cooking frozen chicken in a slow cooker or crock pot because slow cookers cook at a low temperature and may not heat chicken up to 165F, which is the minimum temperature to destroy any dangerous bacteria and ensure that chicken is fully cooked. So if you’re using a crock pot or slow cooker to make Crack Chicken, make sure to defrost it first!
Sleep enough – for most people at least seven hours per night on average – and keep stress under control. Sleep deprivation and stress hormones raise blood sugar levels, slowing ketosis and weight loss a bit. Plus they make much it harder to stick to a keto diet, and resist temptations. So while handling sleep and stress will not get you into ketosis on it’s own, it’s still worth thinking about.
Although many hypotheses have been put forward to explain how the ketogenic diet works, it remains a mystery. Disproven hypotheses include systemic acidosis (high levels of acid in the blood), electrolyte changes and hypoglycaemia (low blood glucose). Although many biochemical changes are known to occur in the brain of a patient on the ketogenic diet, it is not known which of these has an anticonvulsant effect. The lack of understanding in this area is similar to the situation with many anticonvulsant drugs.
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. 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. 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.
Think about what’s happening. Your cells are resisting insulin, causing your body to make a lot more. With all this extra insulin in your blood, you could experience low blood sugars. This is called hypoglycemia, a word made from hypo (low) and glycemia (glucose in the blood). Hypoglycemia is caused by too much insulin in the blood and is a prediabetic symptom. Signs of hypoglycemia include cravings for carbs and sweets, being irritable, moody or depressed, having vision problems, being hungry or dizzy, and the list goes on and on. Your brain is the first organ to feel the effects of low blood sugars.
With a ketosis diet, you tend to eliminate more calcium than usual. Additionally, foods such as cruciferous vegetables, spinach, iced tea or chocolate all have a high quantity of oxalates. Oxalates are naturally occurring substances found in a wide variety of foods; they play a supportive role in the metabolism of many plants and animals, including humans. Oxalates combined with calcium can cause kidney stones.
What's more, studies that have examined the efficacy of the ketogenic diet for weight loss have a few questionable similarities. First, they use the keto diet in conjunction with an extremely low-calorie plan (under 1,000 per day!), which makes it difficult to determine what caused the actual weight loss. Second, they all question the long-term impact on your heart of eating mostly saturated fat, not to mention how hard (and boring) it is to eat mainly coconut oil and butter for months on end.
I eat relatively healthy and fairly low carb (I am already gluten free). I am interested in getting into Ketosis for the the health benefits, but am quite thin for a guy and don’t want to lose any weight. I look at the sample diet above and am pretty sure I would drop weight quickly (I consume about 2,500+ calories daily now). I eat 3 meals plus 2-3 snacks (snacks mostly of nuts (with raisins that would have to go), greek yogurt (would switch to plain), peanut butter, cheese and fruit (would need to reduce qty)). Would eating straight up butter be ok for additional calories also once I am in Ketosis?
Switching to a ketogenic diet plan can be uncomfortable at first because your body metabolism is refitting itself to burn fat instead of relying on glucose. However, you can avoid most of the symptoms. Here's a list of all of the common side effects that will happen the first week or so of starting a ketogenic diet. Knowing about them allows you to take steps to minimize them, and save yourself some carb withdrawal misery. Dr. Mike Eades has a great analogy for this process in this blog post. I highly recommend you read it.
High-Fat Cheeses — Although hard cheeses make for a great keto snack, they aren’t the best cheese for increasing your fat intake without getting too much protein. The highest fat cheeses that can serve as ideal high-fat, low protein snacks are mascarpone cheese and cream cheese. Feel free to combine them with other snacks in this article, such as pork rinds, pepperoni, and nuts, for a wonderfully tasty keto snack.
In many developing countries, the ketogenic diet is expensive because dairy fats and meat are more expensive than grain, fruit and vegetables. The modified Atkins diet has been proposed as a lower-cost alternative for those countries; the slightly more expensive food bill can be offset by a reduction in pharmaceutical costs if the diet is successful. The modified Atkins diet is less complex to explain and prepare and requires less support from a dietitian.
In terms of weight loss, you may be interested in trying the ketogenic diet because you’ve heard that it can make a big impact right away. And that’s true. “Ketogenic diets will cause you to lose weight within the first week,” says Mattinson. She explains that your body will first use up all of its glycogen stores (the storage form of carbohydrate). With depleted glycogen, you’ll drop water weight. While it can be motivating to see the number on the scale go down (often dramatically), do keep in mind that most of this is water loss initially.
We all know fat is more filling than carbs, but every now and then you get a hankering for something to snack on and you NEED some low carb snacks. Whether it’s salty, sweet or frosty, we all need a moment to enjoy something in between meals. Being on a diet shouldn’t mean all snacks are thrown out the window, being on a diet means learning what your body needs and how to best provide for it. If your body is craving something salty, there are ways of indulging without setting yourself back. There are ways of eating even brownies and cakes that won’t undo all your progress.
I didn’t feel empty from their veggie pho, and my food-chef friend commented my rainbow salad smelled and looked tasty. Even the hard-boiled eggs were perfect and the juices complemented the plan from day to night. With fewer carbs for lower-insulin, I noticed an easier drop of sugar, at least while I was on the Keto meal plan complete with juices.

Low Carb Bars — There are a plethora of “keto-friendly” on-the-go bars that have hit the store online and on the shelves. Before you fall for their marketing scheme, check the ingredients and calculate the net carbs per bar. Make sure the bar will fit within your calorie and net carb limits for the day. The two most common bars that can be eaten on keto, albeit sparingly, are Quest Bars and NuGo Smarte Carb Bars. Use these as a last resort if you have no other keto snacks available.
Hi Maya. I LOVE your site!! Interesting, informative with fab recipes and ideas. Hubby and I have just started eating low carb and I have to say, we are not finding it too difficult and I already feel sooo much better!! I find the hardest part is choosing low carb veg, I feel as if we are not eating enough. Any suggestions on how to get more veggies into our diet?
Even if you are starting a ketogenic diet plan for weight loss purposes, don't focus on your weight. Don't weigh yourself every day. Your weight can vary between 2-4 pounds each day because of changes in water intake and absorption. You won't be able to track any fat loss accurately on a daily basis, and the fluctuations will make you crazy if you focus on them. Instead, weigh yourself once a week, or keep track of your body measurements to track your progress. Better yet, focus on the health benefits and the long term health changes that come with eating a low carb diet. Knowing that you are greatly improving your health is a powerful reason to stay with a ketogenic diet plan, even if you don't lose any weight. I discuss in more depth the health benefits of a ketogenic diet in this article published in the July/August issue of the Well Being Journal. I recommend getting a health check up and a blood panel test done just before starting the diet, so that you can track the effect of the change in your eating habits on your cholesterol, blood pressure, and other health markers. Four to eight weeks later, you can get another blood test done and see if there are improvements.
Rethink the heavily-promoted idea that vegetables and whole grains are the healthiest foods to eat. They are not. Animal foods offer greater amounts of more easily-absorbed nutrients and vegetables and grains contain many natural toxins. I'm not saying don't eat vegetables, they do provide some benefit. I am saying give up the grains, the negative effect of these foods outweighs any nutritive value they have.
Some people don't do well in ketosis. As I mentioned above, you should check with your physician if you have any concerns about starting a ketogenic diet plan with pre-existing health conditions, especially if those conditions involve kidney or heart problems. Although there is evidence that many people do well with reducing carb intake, I don't recommend going much lower than 10-20 carbs per day. The ketogenic is a very low carb diet, but it is not a zero carb diet. If you find (after at least a month on the diet) that you are one of the people who doesn't feel well at very low carb levels, adding enough carbohydrate in the form of sweet potatoes and other starchier vegetables back into your diet should bring you out of ketosis and resolve the issues. If you stay away from grains and rely on vegetables, a moderately higher carb content (60-100 grams/day) should result in health benefits. You won't be in ketosis of course, but still, you should feel better. (I think grain consumption is one of the root causes of illness, but also acknowledge that everyone is different.)
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.
