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.”
Other forms of ketogenic diets include cyclic ketogenic diets, also known as carb cycling, and targeted ketogenic diets, which allow for adjustments to carbohydrate intake around exercise. These modifications are typically implemented by athletes looking to use the ketogenic diet to enhance performance and endurance and not by individuals specifically focused on weight loss.
Kale, mushrooms, onions, etc all have a surprising amount of carbs, but aren’t included in this three day kickstart. The weekly menu plans have specific serving sizes but it’s not necessary in this three day kickstart if you eat on plan and don’t deviate – as proven by the hundreds if not thousands of people who have had success with it. If you follow the three day kickstart as written you will get into ketosis.
So I’m late to the party, but I just found your blog last week. I can’t thank you enough for these simple, easy to follow recipes, meal plans, and shopping lists! They are so helpful and I appreciate the time you put into this. I did the 3 day kickstart for 5 days, mostly because I still had leftover food, and I’ve lost 5 lbs. so far! I’ve never done low carb before, and usually eat a mainly vegetarian diet, so this is very different for me, I think I purchased more meat in the past week then I have in the past year! I am strictly following the plan, but do you think after I’ve lost the weight I’ve wanted to, transitioning back to a vegetarian diet (with eggs and dairy) is possible or just a recipe for disaster?
So happy I found your site, out of all the keto sites I’ve clicked on yours is the best!! You actually give us a plan to get started and I love your humor :) I’ve tried living keto before but it was the diet along with a lot of supplements and nasty shakes…it wasn’t for me! I don’t like drinking my snacks and meals just to get into ketosis! Looking forward to trying this again and trying your recipes!
Hi Mel, Assuming that your ranch dressing doesn’t have sugar added, you don’t need to worry too much about limiting it, but within reason. This is my homemade ranch dressing recipe, which has 0.9g net carbs per 2-tbsp serving. It would be hard to find a store bought one with much less than that, even though some round anything less than 1g down to 0g, which isn’t truly accurate. Also, keep in mind that if weight loss is your goal, some people find that too much dairy can cause a stall. Finally, make sure you aren’t using all your “available” carbs on ranch dressing – have it with some low carb veggies!
A modified version of the ketogenic diet, which allows you to eat protein more liberally — at 20 to 30 percent of your total calories — with the same carbohydrate restriction, is the more commonly used version of the diet today. Some of the aims of the latest version of the ketogenic diet are weight loss, weight management, and improved athletic performance.

First, I want to thank you for all of your dedication and work in providing this site. The difficulty of maintaining a healthy weight is a big problem for so many people. My personal question & issue in staying on Keto is my craving for fresh fruit. This a.m I had a large fresh peach along with my “Bullet Proof” coffee. Have I now sabotaged today’s Keto eating?
Today is the 9 th day morning since I started 3 day kick start. Total of 4.6lb loss. 3 days ago I started to feel dizzy and sore throat( partially keto flue?), so I made beef bone broth and used lite salt all day yesterday and a lot of lemon in my tea and seems like it helped.last few days my husband has been loving the bacon and cream cheese pancake, creamy cauliflower on top of 10 minutes chile ( kind like a shepards pie?)and chocolate mousse for the dessert which is all considered no no for his diet plan.He has been carefully watching scale every day and he is still losing as much as his original packaged food plan. At this point he is still doing half and half and being skeptical but he can’t help himself to resist delicious and good looking food anymore!
Thanks for all the good info! I continue to come back and re-read some posts to stay motivated and informed. I have been low carb for about 1.5 months and have lost about 18 pounds. But I continue to have awful night sweats and periods of “flashes” during the day. Would that be considered some of the hormonal changes you referred to? They are very aggravating and interrupt my sleep. BUT they are worth it for the positive effects!

Natural fat, high-fat sauces – Most of the calories on a keto diet should come from fat. You’ll likely get much of it from natural sources like meat, fish, eggs etc. But also use fat in cooking, like butter or coconut fat, and add plenty of olive oil to salads etc. You can also eat delicious high-fat sauces including Bearnaise sauce etc., or garlic butter (recipes).


The keto diet changes the way your body converts food into energy. Eating a lot of fat and very few carbs puts you in ketosis, a metabolic state where your body burns fat instead of carbs for fuel. When your body is unable to get glucose from carbs, your liver converts fatty acids from your diet into ketones, an alternative source of energy. Burning ketones in place of glucose reduces inflammation and spurs weight loss.[1] 
0.2 loss today and I was not hungry yesterday. So I think this is better to eat a bit more for my satiety , slower loss but more sustainable. I was able to talk my husband into eating bacon and egg this morning! Slowly easing him into converting. I want to be able to make a meal that whole family can enjoy instead of making many separate meals for each individual( way too much work!).
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.)

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.
UPDATE: Hi! It’s been 4 weeks already. I am still cooking keto and enjoying many delicious dessert too! I have finally convinced my husband to totally convert to keto food. It’s only been one week since he stopped using diet package food. He is very happy with the food he get to eat and still losing weight but much slower pace this week. That’s because I have been giving him larger portions as this is the first week for him. Since he was already on low carb diet prior to this, keto flue may be not as bad but still want to keep him happy and better transition experience. Meanwhile, I get to cook keto for the whole family and really enjoying the new way of eating and cooking. I have lost total of 6 lb but that was enough to prove to my husband eating bacon and butter is ok as long as we are on keto diet. I was only doing this to convert my husband since he doesn’t have any interest in nutrition or theory behind it, so what he sees is what he believes. 6 lb may not sounds a lot for 4 weeks but I was already below average weight , so it was a lot of loss for me. I think it’s a science 5-30-65 combination works on everyone. Now I just eat more portions of everything ,so we can still eat same food. Today, he had a once a week appointment with his ideal protein dietitian. Seems like they are not convinced that he can still continue to lose weight unless he eat their packaged food. I plan to continue sending him there for once a week appointment , so he sill have something to be accountable for. Next few weeks, I’m hoping he won’t be as hungry so I can start portion control his food without his knowledge, LOL.
"You can find a lot of "fat bomb" recipes on the Internet," Wittrock says. "These are very good at satisfying your sweet tooth, and are a great way to increase fat consumption without going over on protein. Also, I'm a huge fan of salted pumpkin seeds and salted sunflower seed kernels. Believe it or not, pork rinds are also a very good keto snack."

It seems strange that a diet that calls for more fat can raise “good” cholesterol and lower “bad” cholesterol, but ketogenic diets are linked to just that. It may be because the lower levels of insulin that result from these diets can stop your body from making more cholesterol. That means you’re less likely to have high blood pressure, hardened arteries, heart failure, and other heart conditions. 
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.
Well 18 is pretty close to 20, and I’m so mad at myself for letting it happen! I kept thinking I could lose it all fast by getting back on the wagon, but now it will probably take me months. So irritating! Congrats on three pounds and getting a head start on us! Keep us posted in the weekly Saturday thread on how you’re doing OK? And yes, DRINK MORE WATER! ha ha!
But if no carbs are available, our bodies start burning fat as a primary fuel source and producing ketones in the liver, which the body can turn into energy. This metabolic state, called ketosis, is what happens when someone is starving. But it's also how Harper's body works every day. His system relies on fats like butter, oil, and lard as a primary energy source instead of packing them on as in-case-of-emergency poundage.
A short-lived increase in seizure frequency may occur during illness or if ketone levels fluctuate. The diet may be modified if seizure frequency remains high, or the child is losing weight.[18] Loss of seizure-control may come from unexpected sources. Even "sugar-free" food can contain carbohydrates such as maltodextrin, sorbitol, starch and fructose. The sorbitol content of suntan lotion and other skincare products may be high enough for some to be absorbed through the skin and thus negate ketosis.[30]
I love your sense of humour and vigour when explaining the ketone thingy. I started it last year and lost 23 kgs/50 pounds in just under a year. Never looked back but I too have a sweet tooth when it comes to fruit and this took me out of ketones and my motivation took a downer. Back on track and its my day 3 and already in ketones. Put on 2 pounds since my cheating but I had never lost all my weight. Had 10 kgs still to go. My entire family and their spouses are ketone believers. I often found that if I increased my fat with bulletproofcoffee it helped me with my sugar cravings. Also I have found that keeping boiled eggs and chicken in the fridge helps with my nibbling. Use a lot of mayo. Eggs full you up. Thank you. Take are and happy Low Carb eating.

I just want to say THANK YOU for putting together such an informative, encouraging, and realistic introduction to what it means to follow a Keto plan. I have finally decided that I can no longer put off giving myself a food makeover. Started following the Keto guidelines today, and I’m determined to stick with it. Your site gives me the confidence to be able to do it. Thank you!
Those issues can be part of what's known as the “keto flu,” Warren says. Other side effects of the keto diet, all of which are tied to carb withdrawal, can include lightheadedness, nausea, mental fog, cramps, and headaches, in addition to tiredness. Luckily, the keto flu doesn't usually last more than a week—which is coincidentally about when people start to see the number on the scale go down, says Warren.

You’ll need to eat plenty of avocado, coconut, olive oil, beef, chicken, low starch veggies, etc. Strict Paleo avoids both dairy and soy products – I’d start there and eliminate some of the carbs they allow and you should find plenty of recipes you can use for ketosis. Also try the Whole 30 which isn’t keto but eliminates dairy, soy and a few other common allergens and I lose weight on it every time even when I’m not in ketosis. Hope that helps and that you find something that works for you!
The first modern study of fasting as a treatment for epilepsy was in France in 1911.[12] Twenty epilepsy patients of all ages were "detoxified" by consuming a low-calorie vegetarian diet, combined with periods of fasting and purging. Two benefited enormously, but most failed to maintain compliance with the imposed restrictions. The diet improved the patients' mental capabilities, in contrast to their medication, potassium bromide, which dulled the mind.[13]

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.
Hi Mellissa! A big huge THANK YOU for making this transition an easy one! Today was my day 4 so I weighed this morning after following the three day kick start and I am down exactly 5 pounds. I understand that this is usually water weight, but who cares! I used the KetoStix today and am officially in KETO! I really appreciate all of the hard work you have put into this. The recipes are simple and delicious. I am beyond excited to continue this journey…45 pounds to go! Thank you, Thank you, Thank you!!!
When your body burns its stores of fat, it can be hard on your kidneys. And starting a ketogenic diet -- or going back to a normal diet afterward -- can be tricky if you’re obese because of other health issues you’re likely to have, like diabetes, a heart condition, or high blood pressure. If you have any of these conditions, make diet changes slowly and only with the guidance of your doctor.

It’s probably keto flu, make sure you’re drinking lots of water – get plenty of sodium, magnesium supplements and lite salt (potassium) are also helpful. It should only last another day or two until your body adjusts, but if you feel really bad then don’t push it or check with your doctor because something else could be wrong with you. Hope you feel better soon!


Since this is my full-time job, donations really help me keep afloat and allow me to post as much to the website as I do. While I do really appreciate any donation you want to give, you can enter $0 in the amount given to download it for free! I’ve added in $5 as the suggested price. I think that’s a very fair price considering other websites are charging in the hundreds of dollars and I’ve seen what they are like on the inside.
Long-term use of the ketogenic diet in children increases the risk of slowed or stunted growth, bone fractures and kidney stones.[3] The diet reduces levels of insulin-like growth factor 1, which is important for childhood growth. Like many anticonvulsant drugs, the ketogenic diet has an adverse effect on bone health. Many factors may be involved such as acidosis and suppressed growth hormone.[37] About 1 in 20 children on the ketogenic diet will develop kidney stones (compared with one in several thousand for the general population). A class of anticonvulsants known as carbonic anhydrase inhibitors (topiramate, zonisamide) are known to increase the risk of kidney stones, but the combination of these anticonvulsants and the ketogenic diet does not appear to elevate the risk above that of the diet alone.[38] The stones are treatable and do not justify discontinuation of the diet.[38] Johns Hopkins Hospital now gives oral potassium citrate supplements to all ketogenic diet patients, resulting in a sevenfold decrease in the incidence of kidney stones.[39] However, this empiric usage has not been tested in a prospective controlled trial.[9] Kidney stone formation (nephrolithiasis) is associated with the diet for four reasons:[38]
