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.
You’re transitioning. Your body is equipped to process a high intake of carbs and a lower intake of fat. Your body needs to create enzymes to be able to do this. In the transitional period, the brain may run low on energy which can lead to grogginess, nausea, and headaches. If you’re having a large problem with this, you can choose to reduce carb intake gradually.
I’m also going to note that I consider this a diet for your introductory period, as I’ve always added berries and other things in after a couple of weeks with no bad effects. Your stomach shrinks so much that suddenly a couple strawberries are like eating a seven layer chocolate cake. If this is your first time hearing about the keto diet, learn more about it here.

Polyunsaturated Fats. Naturally occurring polyunsaturated fats are good (like found in meat and fish).  But, processed polyunsaturated fats are bad for you. In general, polyunsaturated fats are unstable and not suitable for high-heat cooking. Polyunsaturated fats include omega 3 and omega 6 fats which are essential fatty acids that your body needs for brain function and cell growth. 

Over 8–10 mmol/l: It’s normally impossible to get to this level just by eating a keto diet. It means that something is wrong. The most common cause by far is type 1 diabetes, with severe lack of insulin. Symptoms include feeling very sick with nausea, vomiting, abdominal pain and confusion. The possible end result, ketoacidosis, may be fatal and requires immediate medical care. Learn more
I see your point – but at the same time some people are squeamish about the normal terms and when I first heard shark week I laughed out loud so I thought it might be fun to inject some humor into a sometimes totally humorless subject, especially for people who have really painful and debilitating cycles every month. Glad you’re enjoying the site though and thanks for letting me know! :)
And finally, I couldn’t talk about healthy fats without telling you about fish oil. While you won’t be adding this to your food, it is an important supplement to your diet, and will increase your blood ketones dramatically. I take two tablespoons of Carlson’s lemon-flavored liquid cod liver oil daily to infuse my body with healthy omega-3 fats as part of my heart-healthy regimen. There are fish oil capsules and tablets available at drug stores, but many of these tend to be rancid, and therefore counterproductive. That’s why I prefer the liquid fish oil. In case you’re worried about the “fishy” taste of this stuff in your mouth, it’s actually a delightfully pleasant “lemony” taste. I couldn’t imagine going through my day without taking my liquid fish oil, and the resulting blood ketone levels make it worth it!

Meat – like grass-fed selections – and fresh veggies are more expensive than most processed or fast foods. What you spend on Keto-friendly foods will vary with your choices of protein source and quality. You can select less-expensive, leaner cuts of meat and fatten them up with some oil. Buying less-exotic, in-season veggies will help keep you within budget.
Beyond being high in healthy fats, research has shown that people who include nuts in their diet are likely to live longer than those who don't. The right type of nut can be a great keto-friendly snack. The thing to remember with the keto diet is that you're looking specifically for low-carb, high-fat foods. Certain nuts meet this criterion and should be included in your keto meal plan in moderation. Listed in order of lowest to highest carb content per 1-ounce serving, the best nuts for the keto diet include:
Bear in mind that those macronutrient ratios refer to calories from fat, protein, and carbohydrate, not actual grams of each. Protein and carbs have 4 calories per gram and fat has 9 calories per gram, so it’s actually a relatively easy task to let your fat calories pile up to keto-appropriate proportions if you consume fattier proteins and embellish your food with an extra bit of pure fat. To illustrate, if a portion of a particular food has 10 grams of protein, 10 grams of fat, and 0 grams of carbohydrate, that portion contains 130 calories, 90 from fat and 40 from protein, and is about 69.2% fat and 30.7% protein (allowing for rounding).
Just found this (link from All Day I Dream About Food on FB), but I’m on it! Starting 3-day kickstart today, then wil jump into week 1 and 2 meal plans. I just want to thank you for putting together something I can realistically follow, not confusing, and has everything I need to know all in one place! I have had a very similar low-carb gluten-free journey to what you describe, and knew that keto was going to be the solution. I had lots of info sources, but even more questions – and you answered them! Thank you, thank you – you ROCK!

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.


Nuts may offer unsaturated fats, but they also contain carbs, so look at the label to calculate exactly what you’re getting, says Whitmire. As an example, 1 tbsp of almond butter has 98 calories, 3 g of protein, 9 g of fat, 3 g of total carbs, and about 1.5 g of fiber (equaling about 1.5 g of net carbs), per the USDA. And, the USDA also notes, a 1-ounce (oz) serving of almonds (23 almonds) has 164 calories, 6 g of protein, 14 g of fat, 6 g of carbohydrates, and 3.5 g of fiber (totaling about 2.5 g net carbs).
It seems like everyone is talking about the keto diet — the high-fat, low-carb eating plan that promises to turn your body into a fat-burning machine. For that reason, keto has surged in popularity over the past year as a lose-weight-fast strategy. Thank Hollywood A-listers and professional athletes like Halle Berry, Adriana Lima, and Tim Tebow who’ve publicly touted the diet’s benefits, from shedding weight to slowing down aging. Here’s everything you need to know about going keto.
Secondly, nuts seem to me to be a likely part of a paleo/evolutionary diet. They don’t fight back, nor do they run, qualities I suspect our hunter-gatherer ancestors appreciated. So long as they are in the shell, they keep well with no preparation — you don’t have dry them, smoke them, whatever. And they offer substantial calories for the work involved.
My Husband and I started doing Keto July 2018. We got over weight after we got out of the Marine Corps. It has been hard to workout because I became disabled, but my diet was not good. After our friend Amber recommended your site and support group, we found a lot of helpful information to get us started on a successful journey. So far it’s been one month and we have lost 18 pounds each!

Despite its bad reputation, consuming the egg yolk is a key part of receiving all the great health benefits eggs have to offer.  The egg yolk is concentrated with essential nutrients like folate, B12, zinc and choline.  It is also rich in the fat burning compound conjugated linoleic acid (CLA) and the powerful and hard to get fat soluble vitamins A, D, E and K2.
ShenaynayTaytay Of course I’ve heard of erythritol, it’s just not considered “natural” by the paleo folks who I listen to in terms of calling a sweetener natural. Erythritol is the “safest” but is still tied to leaky gut, etc. It also requires a significant amount to sweeten recipes, rather than a pinch of stevia. Everyone is welcome to use whichever sweeteners they like, I even use sucralose sometimes. These are my “best practices,” not rules. 🙂
Often caused by lymph node removal or damage due to cancer treatment, lymphedema occurs because there’s a blockage in the lymphatic system and results in the swelling in leg or arm. A 2017 study involved patients who suffered from obesity and lymphedema and who embarked on a 18-week ketogenic diet. Weight and limb volume was significantly reduced. (5)
If you choose to make your sauces and gravies, you should consider investing in guar or xanthan gum. It’s a thickener that’s well known in modern cooking techniques and lends a hand to low carb by thickening otherwise watery sauces. Luckily there are many sauces to choose from that are high fat and low carb. If you’re in need of a sauce then consider making a beurre blanc, hollandaise or simply brown butter to top meats with.
One of the major keys to my success with nutritional ketosis has been a very deliberate increase in fat consumption. I haven’t been afraid to eat fat on my low carb diet; in the absence of carbs it is the body’s fuel source. But pushing fat levels even higher while restricting carbohydrate and protein has made all the difference in the world. I remember when I first began this experiment, I got a lot of e-mails from readers who asked how I got my fat consumption up to 85% of my calories. Some joked, “What are you doing, drinking butter?” I can’t help but laugh at this notion, but it does allow me to make this a teachable moment for people who may be unfamiliar with the differences in the macronutrients.
Fruits are high in sugar and carbs. That includes tropical fruits, fruit juices, dried fruits and also the fruit smoothies. Avoid dragon fruit, peach, nectarine, kiwi, grapefruit, apple, orange, plums, cherries, pears, pineapple, mango, banana, papaya, fruit smoothies, fruit syrups, fruit concentrates. This also includes dried fruit like dates and raisins.
Thank you! Yea, no bread/pasta for me, by all accounts I was eating a (what I thought and what everyone would tell me, even a dietician I went to!) ‘healthy’ diet of whole grains, rice, fruit, vegetables, low fat, etc. and couldn’t understand why I was steadily gaining weight. That’s what led me here, as I was getting so frustrated and the more I read up on low carb/ketosis and how the body processes even conventionally healthy foods, it made sense to me, but I don’t think I can give up oatmeal and fruit forever! So I will definitely just make sure I only eat those in small amounts, but that is much farther down the road anyway.. I’m on to Week 1 and I’ll post an update at the end of the week. Thanks again!
A small Feb. 20, 2017, study looked at the impact of a six-week ketogenic diet on physical fitness and body composition in 42 healthy adults. The study, published in the journal Nutrition & Metabolism, found a mildly negative impact on physical performance in terms of endurance capacity, peak power and faster exhaustion. Overall, researchers concluded, “Our findings lead us to assume that a [ketogenic diet] does not impact physical fitness in a clinically relevant manner that would impair activities of daily living and aerobic training.” The “significant” weight loss of about 4.4 pounds, on average, did not affect muscle mass or function.
