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.”
Staying in Ketosis long-term: Chronic Ketosis can cause fatigue, muscle soreness, insomnia and nausea. "Unless you have a medical condition that requires you to stay in Ketosis for long-term, you shouldn't stay in that state for a prolonged period without any carb ups," Mavridis suggests. And if you're a beginner, "it’s recommended that you go through the fat-adaptation phase so that your body becomes accustomed to burning both glucose and fat for fuel," says the nutritionist.
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 keto diet is one of the most effective that I’ve come across and one of the more straightforward (as opposed to easy!) to follow. In a nutshell, when you’re on a keto diet, you eat a very low-carb, high-fat diet. That means goodbye pasta and bread, hello cheese and oils. It’s pretty much the opposite of what we’ve been taught our entire lives. But it works if you follow the keto diet food list. Plus, you can make many favorite recipes keto-friendly.


It usually takes three to four days for your body to go into ketosis because you have to use up your body's stores of glucose, i.e., sugar first, Keatley says. Any major diet change can give you some, uh, issues, and Keatley says he often sees patients who complain of IBS-like symptoms and feeling wiped out at the beginning of the diet. (The tiredness happens because you have less access to carbs, which give you quick energy, he explains.)
In the mid-1990s, Hollywood producer Jim Abrahams, whose son's severe epilepsy was effectively controlled by the diet, created the Charlie Foundation to promote it. Publicity included an appearance on NBC's Dateline programme and ...First Do No Harm (1997), a made-for-television film starring Meryl Streep. The foundation sponsored a multicentre research study, the results of which—announced in 1996—marked the beginning of renewed scientific interest in the diet.[1]

Which leads us to your personality. You need to be VERY strong willed to follow this diet. It follows very strict rules and you need to be able to commit to this. It makes it hard to eat out with friends or eat with friends in general. It’s hard to find food that fits this diet in common restaurants, but and this takes us to the next point, your health goals might be more important.

My numbers come out similar to yours. I’m confused about your daily menu example, though. I figure I can only eat 70g or 2 – 3 oz of meat per day. That is one very small piece of meat. But you show meat at every meal. Also, the fat requirement is about equal to one cup of lard. How do you do that if you’re on the go and want to, say, pack a quick lunch? Or if you’re traveling?
These affect your brain and spine, as well as the nerves that link them together. Epilepsy is one, but others may be helped by a ketogenic diet as well, including Alzheimer’s disease, Parkinson’s disease, and sleep disorders. Scientists aren’t sure why, but it may be that the ketones your body makes when it breaks down fat for energy help protect your brain cells from damage.
Because the ketogenic diet alters the body's metabolism, it is a first-line therapy in children with certain congenital metabolic diseases such as pyruvate dehydrogenase (E1) deficiency and glucose transporter 1 deficiency syndrome,[34] which prevent the body from using carbohydrates as fuel, leading to a dependency on ketone bodies. The ketogenic diet is beneficial in treating the seizures and some other symptoms in these diseases and is an absolute indication.[35] On the other hand, it is absolutely contraindicated in the treatment of other diseases such as pyruvate carboxylase deficiency, porphyria and other rare genetic disorders of fat metabolism.[9] A person with a disorder of fatty acid oxidation is unable to metabolise fatty acids, which replace carbohydrates as the major energy source on the diet. On the ketogenic diet, their body would consume its own protein stores for fuel, leading to ketoacidosis, and eventually coma and death.[36]
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!

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.
Hi Melissa! So I went on ideal protein to lose weight before my daughter’s wedding. It was great! I loved the products and of course I loved losing 64 pounds. HOWEVER, after the wedding I started to enjoy drinking again. And since July 2014, I have gained 34 pounds. I have yo-yo’d with IP but after the taste of real food it is very difficult for me to stay on track. I know it works but after 3 weeks losing 9 pounds I end up eating a whole pizza! Anyway, I love all of your insight to keto. How do you think your suggestions will work if I am throwing in a IP packet for snack instead of say almonds? I just want to feel better again and not spend $100 every week on IP. Thanks for your time and commitment to helping those of us who are weak!
I don’t know how much cheese is ‘too much’ as I’m sure it varies for everyone, but I know that on the Atkins plan they recommend only having 3-4 ounces per day, as cheese does have carbs, anywhere from .4g/oz. (cheddar) to .9g/oz. (parmesan). So, I would just make sure that you’re accurately calculating the carbs and keep your daily total under 20g. Hope that helps!
By the way, I love your blog. I started following you on Pinterest probably about 2 years ago when I started in on the Paleo WOE. I only survived about 3 months of that before I fell off the wagon but I am back now and more ready than ever to finish losing this weight and be truly healthy! Anyway, I saw the name of your site on Pinterest and it made me giggle because that is so me. Your Jalapeno Chicken Wings are on my menu for tonight.

I’m thinking about trying Keto for the very first time in order to help my hormone levels and lose some weight. As I scrolled through your menu plan, I clicked on some recipes. I noticed that they included fruits/veggies that weren’t included in the menu. For example, there are strawberries with your cream cheese pancakes and chocolate mousse. There is also red pepper with the chilli and lettuce with another item (maybe the chilli or the tuna?) Are these items calculated in the carb count for the plan? I have NO CLUE how to calculate net carbs or even calculate carbs using fresh fruits/veggies. Are there any fresh fruits/veggies that are freebies like lettuce or cucumbers? I really don’t want to botch this and feel even worse or lengthen the keto flu. Finally, do I need to factor in vitamins that I’m taking (Magnesium, B complex, and D3? Do they have any carbs that I wouldn’t expect? TIA for any insight you can provide.


He is convinced that carbohydrate-heavy, low-fat diets are a major reason we're seeing high rates of diabetes, high blood pressure, obesity, and cancer. That's because a diet high in sugar can quickly raise insulin levels in the body. Over time, those spikes can lead to insulin resistance and eventually to long-term health issues like high blood pressure, Type 2 diabetes, inflammation, and obesity.
In one week my husband lost 1.5 kg because of Keto diet and recipes. Thank you for the insights and tips. I would like to have a complete recipe for meals everyday and hoping by subscribing I will receive try my mail. I will keep u posted. It takes 2 to tango. The one who wants to diet must be cooperative with the plan and execution while the other person who is preparing the food must be patient to the dieting person. Its not easy to change meals so patience is required

So, I started the 3 day kick-start a week ago and am still following the plan! I went out and purchased the cookbook on Thursday and have been pouring over it since. Made the cauliflower mashed potatoes last night and they were awesome. A keeper for my household. Even hubby liked them. I feel great and am feeling the effects of weight loss and no carbs in my system…in a good way. Passed on the carb flu- probably because I had cut way down on the carbs before starting this. I dont miss them a bit…I keep thinking I should increase my carbs, LOL but I m not sure I want to ! Thank you for your book and thank you for your humor and thank you for your motivating spirit!

When you’re eating the foods that get you there (more on that in a minute), your body can enter a state of ketosis in one to three days, she adds. During the diet, the majority of calories you consume come from fat, with a little protein and very little carbohydrates. Ketosis also happens if you eat a very low-calorie diet — think doctor-supervised, only when medically recommended diets of 600 to 800 total calories.
