What's more, it's especially important to make sure your diet is well-planned when you're eating keto-style, because the foods you can choose from are limited. In addition to checking in with a dietitian if you're able, Stefanski recommends that you "talk to your doctor and make sure she or he is aware that you'll be starting a diet that completely changes how your body metabolizes energy." You might also want to check your most recent bloodwork levels for things such as cholesterol, vitamin D, and other indicators of health because these can change while on keto. That's because for some people, a prolonged keto diet can result in certain nutritional deficiencies or even high cholesterol. But most experts will tell you that the ketogenic diet is not a permanent lifestyle change (as could be the case for something like the 80/20 approach to eating or a Mediterranean eating style).
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. 
In 1921, Rollin Turner Woodyatt reviewed the research on diet and diabetes. He reported that three water-soluble compounds, β-hydroxybutyrate, acetoacetate and acetone (known collectively as ketone bodies), were produced by the liver in otherwise healthy people when they were starved or if they consumed a very low-carbohydrate, high-fat diet.[10] Dr. Russell Morse Wilder, at the Mayo Clinic, built on this research and coined the term ketogenic diet to describe a diet that produced a high level of ketone bodies in the blood (ketonemia) through an excess of fat and lack of carbohydrate. Wilder hoped to obtain the benefits of fasting in a dietary therapy that could be maintained indefinitely. His trial on a few epilepsy patients in 1921 was the first use of the ketogenic diet as a treatment for epilepsy.[10]
1) Fat weighs less than healthy muscle… EVEN IF you are not showing a loss in the scales… check your clothes.. they’ll be fitting better… If you lacked good muscle tissue.. eating the protein will rebuild that. If you were VERY out of shape, your body will feel GREAT with all the new muscle, but it DOES weigh more… that will not stop you from losing, you just need to stick it out… you will lose inches even if you’re not losing lbs…
Early studies reported high success rates: in one study in 1925, 60% of patients became seizure-free, and another 35% of patients had a 50% reduction in seizure frequency. These studies generally examined a cohort of patients recently treated by the physician (what is known as a retrospective study) and selected patients who had successfully maintained the dietary restrictions. However, these studies are difficult to compare to modern trials. One reason is that these older trials suffered from selection bias, as they excluded patients who were unable to start or maintain the diet and thereby selected from patients who would generate better results. In an attempt to control for this bias, modern study design prefers a prospective cohort (the patients in the study are chosen before therapy begins) in which the results are presented for all patients regardless of whether they started or completed the treatment (known as intent-to-treat analysis).[18]
You’re so welcome Jessica – you and me both! I’m looking forward to feeling good again and having my clothes fit right will be nice too! ha ha! Thanks to all of your feedback I’ll be posting 7 day menu plans every Saturday, and we’ll all hopefully be reporting our pounds lost so far progress in the comments. I’m so looking forward to it – hope you’ll join us!!!
Those of you who may be new to what they call “keto flu” might panic, thinking your death is imminent. I can assure you that it is highly unlikely that you will die from sugar/carb withdrawal – but just to be sure it’s always wise to consult your doctor before you embark on any new eating plan, or if something feels truly off it’s better to be safe than sorry – seek medical attention if you feel it’s necessary. Most symptoms can be alleviated by supplementing and drinking enough water (see #3 and >4.)
Thank you soooo much for this. I have been a big fan of your recipes for a few months-delicious! I was floundering on my low carb for a while and this holiday season was the first in years that I just ate everything…whatever I wanted. I was left feeling huge, bloated, uncomfortable in my own skin. I had forgotten what I loved about low carb, that it wasn’t complicated and I did get to eat what I loved. Thank you again for reminding that it can be easy and delicious.

because the recipes don’t mention quantities it’s hard to know how much it’s okay to eat of the carb foods. How much carbs is in those foods like kale, cauliflower, lettuce a.s.o. What about mushrooms ? Love to use them as a ‘filler’ instead of bread. Also hard to know how much is too much protein? Cheese, meat, bacon, yoghurt, tuna…. they all are full of protein.


I’ve never heard of this program, but am definitely willing to try it. I do have a question, however; in my faith, we do not eat pig meat in any way, shape or form, so can I eat turkey bacon or sausage instead (for breakfast meats)? I’m not a day person, having worked the midnight shift for almost 20 years, so the meat/breakfast just isn’t relevant–I’d prefer to eat dinner-type foods instead–but if it has to be done in order to lose (a huge amount of) weight, I’ll adjust.

The gist of the eating plan? Taking in so few carbs sends your body into ketosis—a state of burning fat for energy, instead of carbohydrates or sugars, explains Beth Warren, RDN, founder of Beth Warren Nutrition and author of Secrets of a Kosher Girl: A 21-Day Nourishing Plan to Lose Weight and Feel Great (Even If You're Not Jewish). In order to stay in ketosis, you only consume 5% to 10% of your calories from carbohydrates—which for most followers is fewer than 20 grams total per day—and instead eat moderate amounts of protein and high amounts of fat.

Hello Myriam, I am a dual certified personal trainer and Sports Nutrition Specialist. I really love how concisely you have put this article together. I did notice that on your macro breakdown for a 1500 calorie diet you actually listed the protein intake at around 31% of the daily calories (117*4=468..468/1500=.31). I was wondering if you did this to bring the protein amount closer to 1 gram per pound of body-weight to preserve lean mass?

All I can say is WOW! I am a week in on this Keto way of eating and came across this simple recipe. Gotta admit, I didn’t think I would like it…I LOVE IT! So easy to make…took me 20 minutes total! It was light, moist and delicious. I used one small loaf pan, doubled the ingredients and made the regular one and the cheese mix in. Can’t wait to share the rest with my co-workers…we are doing this together. Will be back to check for other recipes. Thank you!
The classic ketogenic diet is not a balanced diet and only contains tiny portions of fresh fruit and vegetables, fortified cereals and calcium-rich foods. In particular, the B vitamins, calcium and vitamin D must be artificially supplemented. This is achieved by taking two sugar-free supplements designed for the patient's age: a multivitamin with minerals and calcium with vitamin D.[3] A typical day of food for a child on a 4:1 ratio, 1,500 kcal (6,300 kJ) ketogenic diet comprises:[27]

For athletes, research on the keto diet highlights potential improvements in athletic performance, especially when it comes to endurance activities. An article suggests ketogenic-type diets may allow endurance athletes to rely mostly on stored fat for energy during exercise rather than having to refuel with simple carbohydrates during endurance training and competition while additionally improving recovery times. (10)

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!

For endurance athletes, the transition to a ketogenic diet may reduce recovery time after training, but for casual exercisers, the transition to the ketogenic diet may make sticking with your fitness routine a challenge at first. (10) If you feel your energy levels drop too much when starting the ketogenic diet, slow down your reduction of carbohydrates, making sure to do it over time rather than all at once.


You’re very welcome, Judy! I’m glad it’s helpful. If you are keto (as opposed to low carb), unfortunately peaches would not allow you to stay in ketosis. You can check my keto food list to help determine what is keto friendly. Of course, there are worse things than fresh fruit 🙂 but in the end our bodies still see the sugar. That being said, it doesn’t mean you sabotaged the whole day. Just pick up again – you got this!! (And for next time, try some fresh berries in moderation when you’re craving fruit.)

Wow Gloria, you really do love this – way to to go! We just need to work on portion control now 😉 The recipe states serves 6. All that info is right at the top of each recipe. Don’t worry, many scroll past it eagerly wanting to get to the recipe itself. It is the beginning of summer there, but I will continue to make this throughout summer as my youngest absolutely loves it.
Along the same vein, some of my recipes on the blog include hemp seeds, coconut flour, almond flour, and other not so easy to find ingredients – IGNORE THOSE RECIPES (for now). The focus here is, again, simplicity. You will likely be irritable, fatigued, and not feeling awesome during the first three days to a week. Trust me on this – the last thing you are going to want to do is make complicated meals.

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.[54]

Do you by chance have a shopping list for this 3 day beginning plan? I am a beginner and am so overwhelmed with information. The best part about your plans is they don’t require a tone of ingredients for 1 recipe. I don’t like when I have to but 15 things for 1 meal. I also love how you have something for breakfast and then can use it again for lunch (day 1 isn’t an example). Thank you so much for taking the time to put these together. Also, for all the information you provided.
Cyclical ketogenic diet: The Bulletproof Diet falls into this category. You eat high fat, low carb (less than 50 grams of net carbs a day) five to six days of the week. On day seven, you up your carb intake to roughly 150 grams, during what’s called a carb refeed day. Carb cycling this way helps you avoid the negative effects some people experience when they restrict carbs long term, like thyroid issues, fatigue and dry eyes.[10] [11] Full ketosis isn’t for everyone, and adding carbs such as sweet potatoes, squash, and white rice one day a week keeps your body systems that need some amount of carbs functioning properly.
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.

There are theoretically no restrictions on where the ketogenic diet might be used, and it can cost less than modern anticonvulsants. However, fasting and dietary changes are affected by religious and cultural issues. A culture where food is often prepared by grandparents or hired help means more people must be educated about the diet. When families dine together, sharing the same meal, it can be difficult to separate the child's meal. In many countries, food labelling is not mandatory so calculating the proportions of fat, protein and carbohydrate is difficult. In some countries, it may be hard to find sugar-free forms of medicines and supplements, to purchase an accurate electronic scale, or to afford MCT oils.[53]

I’d like to add to your last point because my uterus hated me for a week! I have the IUD (Mirena) and I honestly don’t remember when my last period was, guesstimating I’d say 8 months ago. Since having the IUD I only spot and rarely have a period (I’ve had it since 2014), but OMG my hormones must’ve been all over the place because I not only got a heavy period but I had it for 9 days straight!

Hi Stacey, I can’t give medical advice and definitely recommend following your doctor’s recommendations. You can ask him/her if low carb would be better suited for you. Also, you may want to double check with him/her if the kidney concern was related to high protein, because that is a common misconception about keto – it is not a high protein diet/lifestyle.

the biggest challenge most people have is sticking that first week at less than 20 net carbs but this is crucial not only to start losing but to keep losing. Most people don’t really start to notice weight loss till a good week in even then. If you want to jump start you can try a three day fast but then stick to that 20 net carbs and like was stated, know the nutrition facts of what you are eating. Onions for instance have quite a bit of sugar/net carbs. Even if it takes a bit for your body to rev up it definitely will as long as you stick to the carb numbers and fat ratio of 40% total calories
As always, I’m late to the party. Thank you so much for this fantastic resource! I did this 6 years ago, lost 60 lbs. and maintained it for five years. But over the past year or so, my weight has gone up and down the same 18 lbs. To add insult to injury, I’m now borderline pre-diabetic (higher A1C than is healthy), my anxiety attacks have returned and so I’m on medication for that. It’s time to go back to what I know makes me feel better and get off the sugar and garbage once and for all.
In addition to burning fat reserves and super charging weight loss, ketosis produces a clean burning metabolic fuel that has many benefits. Ketones lower production of reactive oxygen species (ROS),1 enhance mitochondrial biogenesis,2 3 and induce positive epigenetic expression.4 Because of its neurological benefits, I went on a Keto Diet in 2014, and it has been helpful in moderating my MS symptoms.
Hello! I recently lost 125 lbs following a keto diet. It’s starting to creep back on. My question is, have you tried a product like Keto OS? I want to eat Keto strictly, minus one meal a week. I feel that I will maintain better this way. I don’t want to knock myself out of ketosis and take days to get back in, though. My hope was that I can go full Keto, have one meal “off” a week and follow up with Keto OS to put me right back in and stay in for another week. Thoughts? Will this work? Thank you!

I love this! I am an amateur powerlifter and I have recently started using the keto diet as there is only so much gained by being a fat powerlifter but working out my macros was driving me nuts as I also work as a disability support worker and need to take meals and so on to work with me. Thanks to this I can now have better control of the macros to bring my weight down without doing to much harm to my lifts! Thank you for this!
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.
The Keto diet emphasizes weight loss through fat-burning. The goal is to quickly lose weight and ultimately feel fuller with fewer cravings, while boosting your mood, mental focus and energy. According to Keto proponents, by slashing the carbs you consume and instead filling up on fats, you safely enter a state of ketosis. That’s when the body breaks down both dietary and stored body fat into substances called ketones. Your fat-burning system now relies mainly on fat – instead of sugar – for energy. While similar in some ways to familiar low-carb diets, the Keto diet’s extreme carb restrictions – about 20 net carbs a day or less, depending on the version – and the deliberate shift into ketosis are what set this increasingly popular diet apart.
