No matter what your diet has been before now, keto will be a big change. If you're coming from a standard American diet (SAD), your carbs will go way down, your protein may either go up or down, and your fat will go way up. If you're coming from a bodybuilding-style diet, your fat intake will jump to alarming levels, and your protein will likely drop significantly.

As ketones levels rise in the body, the cells of heart, brain and muscles begin to use them for fuel. And once the body is using ketones as a main fuel source, there are some profound and positive health effects.  Ketogenic diets are very effective for correcting cellular metabolic dysfunction. The high blood sugar of diabetes gets reversed, the seizures of epilepsy can be calmed, Alzheimers and Parkinsons symptoms are alleviated, extra weight can be lost, joint pain is diminished and so on.  In other words, the ketogenic diet is not a “fad.” It is a potent regulator of metabolic derangement, and when formulated and implemented correctly, it can be extremely effective at reversing all kinds of health problems. (See this paper.)
Initially you may be surprised that on keto diets you eat less frequently.  That’s because the fats are pretty satisfying. But as you normalize and adjust into a ketogenic state, that may change and your appetite may increase.  That’s fine and completely normal.  Use whatever diet you decide to follow as a starting point – it should be “written in pencil” so that you can make changes along the way.  Consider adding an extra meal, marginally increasing the size of the meals or just adding a shake between meals.  It’s up to you – just listen to your body.  For example for me, I added a low-carb “green powder” shake supplement to my regimen along with either flax seed oil or some nuts in order to satisfy my hunger.
The Inuit are often cited as an example of a culture that has lived for hundreds of years on a low-carbohydrate diet.[42] However, in multiple studies the traditional Inuit diet has not been shown to be a ketogenic diet.[43][44][45][46] Not only have multiple researchers been unable to detect any evidence of ketosis resulting from the traditional Inuit diet, but the ratios of fatty-acid to glucose were observed at well below the generally accepted level of ketogenesis.[44][47][45][46] Furthermore, studies investigating the fat yields from fully dressed wild ungulates, and the dietary habits of the cultures who rely on them, suggest that they are too lean to support a ketogenic diet.[48][49] With limited access to fat and carbohydrates, cultures such as the Nunamiut Eskimos—who relied heavily on caribou for subsistence—annually traded for fat and seaweed with coastal-dwelling Taremiut.[48]
Lisa, Yes, it is safe to put cream cheese in the pressure cooker, this is how we always make it. Alternatively, you can add the cream cheese once the chicken is cooked and you take it out of the pot to shred it, but you’ll need to leave the pot on “saute” and cook (stirring frequently) until the cream cheese mixture is melted into the sauce. (You may also need to add a splash more liquid if done this way.) If you try it this way, let us know how it goes!

Keto recipes that include nachos?! Oh yes. You’ll begin by making the fat head tortilla chips first. Did I mention you’ll use two types of cheese for this step? Delicious. Next, you’ll load them up with a meaty sauce and finish them off with your favorite toppings, like guac, salsa or sour cream. While these make a delicious snack, they’re frankly filling enough to share as a meal.

You can use a different brand or look for inulin (it’s basically the same thing, but you can probably find it cheaper). Leaving out the prebiotic fiber will alter the taste and macros, so it’s best to leave it in. If you absolutely want to leave it out, the carb count will go up, the pancakes will taste a bit less sweet, and you would have to add a small amount more flour to get the right batter consistency.
In dairy cattle, ketosis is a common ailment that usually occurs during the first weeks after giving birth to a calf. Ketosis is in these cases sometimes referred to as acetonemia. A study from 2011 revealed that whether ketosis is developed or not depends on the lipids a cow uses to create butterfat. Animals prone to ketosis mobilize fatty acids from adipose tissue, while robust animals create fatty acids from blood phosphatidylcholine (lecithin). Healthy animals can be recognized by high levels of milk glycerophosphocholine and low levels of milk phosphocholine.[76] Point of care diagnostic tests are available and are reasonably useful.[77]
Hi Barb, That can definitely be it. Losing when you are close to goal can be more difficult. It could also be that your body’s healthy weight is a little higher than what you’d like – which doesn’t mean you can’t lose, but makes it more difficult. If just eating Keto foods isn’t working, double check the macros for your weight and see if the amount you’re eating needs to be adjusted. You’ll find more help and support in our support group here.
Yvette, Oh no, sorry to hear about the chicken not being cooked! Was the chicken frozen to start with? If so, be sure to add 5 minutes to your Instant Pot cooking time (on manual high pressure). When we tested this, we literally just put everything into the IP (nestled down into the liquid, of course), and let it do its thing. The cream cheese softened, and when it was done cooking we removed the chicken to shred it, and the sauce stirred together nicely.
As a diabetic and lactose intolerant, this is the only way I can eat ice cream. I add unsweetened cocoa and extra aspartame to make a wonderful chocolate ice cream, then I add chopped up bananas or 1/2 tsp of peppermint extract – yum! Or instead of chocolate, I add lemon and peppermint extracts, together. Great! For the serious chocoholics, melt some dark chocolate in the microwave and add that to the unsweetened cocoa – incredible!
The BBB, largely formed by the brain capillary endothelial cells, provides a protective barrier between the systemic blood and the extracellular environment of the CNS. Passage of FAs from the blood to the brain may occur either by diffusion or by proteins that facilitate their transport. Studies indicate that FATP-1 and FATP-4 are the predominant FA transport proteins expressed in the BBB based on human and mouse expression studies (Mitchell et al., 2011).
Take a multivitamin. “Because you are removing grains, the majority of fruit, some vegetables, and a significant amount of dairy from your menu, a multivitamin is good insurance against any micronutrient deficiencies,” says Jadin. Depending on what your individual overall diet looks like, Jadin says you might also need to add a calcium, vitamin D, and potassium supplement.
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?
Wondering what fits into a keto diet — and what doesn’t? “It’s so important to know what foods you’ll be eating before you start, and how to incorporate more fats into your diet,” says Kristen Mancinelli, RD, author of The Ketogenic Diet: A Scientifically Proven Approach to Fast, Healthy Weight Loss, who is based in New York City. We asked her for some guidelines.
