There are numerous benefits that come with being on keto: from weight loss and increased energy levels to therapeutic medical applications. Most anyone can safely benefit from eating a low-carb, high-fat diet. Below, you’ll find a short list of the benefits you can receive from a ketogenic diet. For a more comprehensive list, you can also read our in-depth article here >

Once you know what you will be eating on keto, you will probably be wondering how much of you should eat for each meal. Since meal size depends on the individual and his/her goals, we recommend using a calorie tracking app and our carb tracking guide to help you figure out the macronutrient content of your meals. As you track your macros, you will be able to figure out what adjusts you need to make to your diet to reach your goals.

Can you lose 15 pounds in 3 weeks


Such a thorough article. Thank you! I have a friend who swears by the KETO diet. However, I’m of the same thinking as you are, that cutting out or eating next to nil of any food group, is not what God meant. Discipline in portion size, and perhaps not combining certain food groups (proteins with heavy carbs is a not best for our digestive system), but both can be eaten when not combined, hence no cutting out of any food group. Thanks again!
I won’t comment on the diet itself but dietitians do not simply rely on guidelines handed to them, nor on anecdotal cases. This article refers to specific studies all throughout, some that support the diet and others that don’t. The goal of a dietitian is to help clients reach their optimal health while still enjoying a high quality of life. I’m sure Abbey is genuinely happy for those it has helped. That does not mean this diet is best for everyone regardless of their unique circumstances, goals and medical history. Sadly there is not enough high quality research that Keto promotes sustained weight loss in the general population. Maybe there will be in the near future, but right now it would be unethical to recommend such a restrictive diet to the broad audience of a blog. I am truly happy it has worked for some people and I wish them luck on their journey. Thank you Abbey for a great article!
The keto diet is high in fat, moderate protein, and low in carbs. You will avoid foods that are high in carbs, including some fruits and vegetables, most vegetable oils (like canola and corn oil) sugar, and grains, to name a few. Instead of going over all the foods to avoid, it is easier to print the keto grocery list pdf at the bottom of this post and stick to those keto foods for simplicity.
A huge concern with the keto diet is the maintenance and potential loss of muscle mass. Many people will just think: hey, dummy, then just eat more protein. However, some research has shown that even if your protein intake remains constant, a low carb diet may promote muscle loss. A study from the Netherlands confirmed these findings. In the study, participants were given three diets (high carb, moderate carb, low carb) and moderate protein. The study found that those following a low carb diet experienced increased muscle breakdown. This is because when we eat carbohydrates, we produce insulin which promotes muscle growth. This is why athletes depend on carbohydrates (along with protein) to fuel their performance. When we eat carbs, the insulin release “unlocks” our muscles to let the protein in so it can do its job at building our muscles. So, when we skip the carbs all together, muscle glycogen stores get depleted, we lose out on those muscle building opportunities. Forget about high intensity training. A depleted glycogen store also means our workouts will suffer because we just don’t have enough oil left in the tank. This was a again suggested in the recent review looking at many ketogenic studies. The studies found that there was greater lean body mass loss in the ketogenic groups compared to the other diets being studied. 

When can you have a cheat day on keto


I love prepping meat days in advance, so I don’t have to cook meat for every meal. Organic processed meats are quick and easy, but they also cost more than cooking, so it’s up to you. Also, be sure to save bacon grease for cooking other foods. I use bacon grease when I fry veggies (if I need extra fat) and chicken and it tastes great! Avoid sauces unless you are using low carb meat sauces or dips.
Noakes’s war on sugar goes back a generation, to when his father developed type-2 diabetes. Type-2 is a disease in which the body gradually loses its ability to regulate blood sugar through the production of the hormone insulin. It’s linked to genetics, but also to diet—particularly sugar and refined carbs—as well as obesity and inactivity. Diabetes experts estimate that the disease speeds up the aging process by roughly a third, damaging the body from the inside out. Too much blood sugar slowly destroys blood vessels, with results ranging from mild—early wrinkling of skin—to catastrophic: heart disease, blindness, stroke, amputations due to poor circulation, and even Alzheimer’s disease (more on that later).
The medical community is failing their patients by continuing to shove the food pyramid in their faces. Let them lose weight in a manner that works best for them — and let them lose it fast so they see results. Im sick of hearing “it’s a lifestyle change” because diets themselves are not meant to be lifestyle changes — they are meant to be a period of weight loss. Show them the lifestyle changes AFTER they lose the weight necessary to become healthy again. How I see it — where people fail and where you are failing them — is not helping them to realistically lose the weight in the first place and then in not teaching them how to maintain their lifestyle using realistic macros guidelines to do so.
This article just goes to show that NOBODY knows wtf they are talking about… For example first saturated fat is bad… years later they “find out” it is healthy… but maybe not? How can there be 2 opposing sides (with intelligent minds on each), about something as simple as what a human should eat?! My doctor told me to try the keto diet to help weight loss and improve my blood lab results. I’m only 2 weeks in but this is the easiest diet ive ever had in my life! I love everything I eat! I doubt our ancestors thrived off pasta, soda, candy, and all the processed boxed garbage the American diet consists of today. Their bread was nothing like the crap bread in stores now either. Fruit and starchy veggies are ok to eat however only in moderation. I’m just fed up with how nutritionist and scientists cant make up their mind about what a healthy diet is.
The walking around part is not true in my experience, exercise alone will not help an obese person. I’ve been doing Keto and most things I’ve read have come true, I found this article to be unbiased. I will say this however, I agree I too have been eating many green veggies and the bad stuff I do use I use very little for flavor (like bacon) what I found that is utterly ridiculous on the part of the folks that did the diet rankings was saying Keto was unsustainable. The way I feel from being on Keto is insanely well. I want to keep eating this way! Unsustainable its the only diet I can do intermittent fasting on. I was type 2….

I give you points for not completely bashing the Keto diet but I have to ask you why do you think it is hard to follow? Do you tell vegans that their diet in unsustainable? I know for myself I can go to almost any restaurant and eat a keto meal the same could not be said with vegans. A properly balanced keto diet would require no vitamins or minerals (the reason for Keto “Flu”) the same can not be said for vegans, most vegans have major deficiencies and some vitamins like B12 are near impossible to obtain without supplements.


This is of course just an overview of what you can eat, but these are things I’m most likely going to pick up from the grocery store. I also didn’t want to include crazy expensive specialty items like Erythritol for beginners. I think we all get excited about making our favorite junk foods in the style of our diets right away. This is fine…but it can be very expensive, time consuming and exhausting. Stick with the basics, especially when first starting out!
First off, I will say the ketogenic diet is not for everyone for their individual health reasons. However, reading through many of the posts where it didn’t work for people I would be willing to bet 90% of the time there is an obvious reason and no offense to that person but maybe a little more research would have helped. Something as simple as consciously increasing salt intake, or taking a multi-vitamin to get the minerals you need could help. Everyone’s body is different and some people can’t eat as much cheese for example (like my wife), as others can. If you feel off, or just don’t feel right before abandoning the diet please look up your symptoms and see if there’s a simple fix. It can really be worth it.

Can I do a modified keto diet


The ketogenic diet has recently become very popular, and many food companies want to cash in by putting a “ketogenic” or “low carb” label on a new product. Be very cautious of special “keto” or “low-carb” products, such as pastas, chocolate bars, energy bars, protein powders, snack foods, cakes, cookies and other “low carb” or “ketogenic” treats. Read all labels carefully for natural low carb ingredients. The fewer ingredients the better.

The 30-Day Ketogenic Cleanse offers a step-by-step guide to approaching what some may see as a lifestyle change. The day by day guide is highly informative as each day’s diet is broken into its constituent parts. This further informs readers as to how their day-to-day diet is working to nourish and improve their body. The book breaks down what it takes to go into a ketogenic state while staying healthy and enjoying truly delectable food. From our standpoint, this really is a great resource and truly one of the best keto cookbooks out there.
Abbey, I appreciate the article, it’s helped me come to a decision on KETO. I’ve been on KETO for over 3 months, I’m a woman of 55 and post menopausal with a good 40 lbs of fat to lose. I work out 3-5 per week at an intense level doing cardio, HIIT and weight training and I have NOT lost any weight (ok, a single pound). I am in Ketosis most of the time (testing often) and I’ve been eating 1,200 to 1,300 cals per day. My carb intake around 15-20 grams per day, Fat around 90 grams and protein was about 45 grams until I increased it after learning I had lost muscle mass confirmed on a SECA scale.
Since the ideal protein intake is fixed based on your lean mass and activity level and your net carbs intake is specified by you, the only macronutrient that needs adjusting is the fat intake. Your fat intake is used to adjust the calorie intake. The more fat, the more calories. Typically, you adjust fat so that you reach but not exceed your target calories.
A ketogenic diet may be an option for some people who have had difficulty losing weight with other methods.  The exact ratio of fat, carbohydrate, and protein that is needed to achieve health benefits will vary among individuals due to their genetic makeup and body composition. Therefore, if one chooses to start a ketogenic diet, it is recommended to consult with one’s physician and a dietitian to closely monitor any biochemical changes after starting the regimen, and to create a meal plan that is tailored to one’s existing health conditions and to prevent nutritional deficiencies or other health complications. A dietitian may also provide guidance on reintroducing carbohydrates once weight loss is achieved.
When you eat foods high in carbohydrates and fat, your body naturally produces glucose. Carbohydrates are the easiest thing for the body to process, and therefore it will use them first – resulting in the excess fats to be stored immediately. In turn, this causes weight gain and health problems that are associated with high fat, high carbohydrate diets (NOT keto).
A typical ketogenic diet is comprised of only 15-25% protein, yet some research indicates that even during a caloric deficit, being in a state of ketosis can preserve muscle mass. It is critical to understand that in some of the literature a low-carbohydrate diet may not actually be a true ketogenic diet. To illustrate, some studies have shown that a very low carbohydrate diet (C:4 F:61 P:35) has similar effects to a traditional low-fat diet (C:70 F:10 P:20) on weight loss. In other words, both groups demonstrated similar losses in fat AND muscle mass (10). However, Dr. Layman (5) performed a study comparing a high protein, moderate fat, and low carbohydrate diet to a high carbohydrate, moderate fat, and moderate protein in conjunction with resistance training. Fat and total calorie intake were equal between experimental groups. Average weight loss was the same between groups but the composition of the weight loss differed. Low-carbohydrate dieters lost more fat mass and less muscle compared to the high carbohydrate group. This data suggests that increasing protein intake during a caloric deficit can help mitigate some of the muscle wasting that often accompanies dieting.

Is Chicken bad for cancer patients


Anyways, I am feeling so much better without the weight, my sleep apnea is gone, my blood glucose is lower and the edema in my legs is gone. But I do have concerns about the saturated fat, my HDL/LDL and I do not like the “nail polish breath”. Once I reach my goal, I plan to transition to more of a Mediterranean style diet but still with logging and I hope to be able to keep the weight off. 

c quoi keto diet

Abbey, I appreciate all the work you put into this but there are a few things you missed. Not all oils are keto friendly. Vegetable oils are a huge no-no which was not mentioned. Regular mayo usually contains soybean oil which should be avoided. You also missed that foods with preservatives are a no-no which excludes some cheeses (you said enjoy all the cheese you like). Processed sliced cheese or pre-shredded cheese in a bag at the grocery store contains preservatives. Ever notice how shredded cheese in a bag never sticks to itself but when you shred your own cheese it sticks? Preservatives. Most nuts are okay but peanuts are a legume and should be consumed in very small amounts or avoided altogether. Don’t go crazy either, nuts do have carbs. I don’t eat more than a half cup a day of salted almonds. That said, you could have mentioned that getting salted nuts is ideal as you do excrete more salt and other minerals in your urine (eating keto is diuretic so attention must be paid to salt, potassium, magnesium, etc. as you did mention) so finding simple ways to add salt and other minerals is helpful. I also take a multi-vitamin daily. You mentioned you cannot do high intensity workouts. You are not supposed to do high intensity workouts as elevating your heart rate too high actually stops the fat burning process in your body. Your heart rate should be 180 beats minus your age +/- 5 beats depending on fitness level. A 40 year old obese person shouldn’t go over 135 beats/min during a workout as that is the optimal fat burning window. Higher than that and your body reverts to storing fat reserves thinking it will run out if it keeps this pace. Which bring me to metabolism. Its been long believed a high metabolism is good. A high metabolism leads to more hunger (because you’re burning glucose faster), ingesting more food, and typically gaining more weight. Slowing your metabolism down AND teaching your body to consume slow burning ketones instead of quick burning glucose puts less stress on your liver mainly and on your body in general. There’s a lot more but this is getting long so I’ll finish with this. You said this diet focuses on quantity of food and not quality. This is confusing to me….wouldn’t organic and grass-fed meats, be of better quality than non-organic and grain fed meat? (they feed animals grains to fatten them up….shouldn’t that be a huge warning sign for us?). Is food without preservatives not better quality than food with preservatives? Aren’t beverages with no sugar or artificial sweeteners of better quality than sugar/artificial sweetener-filled beverages? I’ve never seen any keto advocate advise ignoring quality foods, in fact its quite the opposite.

Why does my pee smell bad even though I drink a lot of water


If you stick to g of carbs, g protein, and g fat, you will eat kcal and lose kg (lbs) in the first month. Keep in mind that your body weight can fluctuate by ±2kg (±4lbs) on any given day from water weight and what's in your stomach. Recalculate your macro ratio once a month! Changes in body composition have a large influence on the recommendations and weight loss.

How do I know Im in ketosis


Studies found that endurance performance, whether it was anaerobic or aerobic was impaired or maintained with a ketogenic diet. This is still a complicated area to study, since majority of studies used in this review had small sample sizes, no control group or were very short in duration (no more than six weeks). Because of this, it is still unclear whether endurance performance is enhanced or impaired with a ketogenic diet.
I am with you! I have been a WW member and been years without going outside of my suggested guidelines. I would lose weight, plateau, go on one of their plateau breaking diets for two weeks then have to go off and slowly gained weight again. I was teaching my body to live on less. I have been down as low as 800 kcal a day and not losing. Eat more fiber so you feel full was what I was told. Try eating 800 kcal, high fiber and see how balanced your diet is. I am eating between 1800 – 2000 kcal now and dropping 10 – 15 lbs a month on Keto. Long term diuretic user, I no longer have water retention. I am salting and using fat and I am off my blood pressure medicine. I am not hungry so I am wondering why is this not sustainable? I eat mostly carbs from vegetables, I eat a variety of meats, I eat a variety of vegetables, I feel great and my blood tests are better than they have been in 2 decades. I am starting to feel that the carb revolution is because we are told by the government what is good to eat. We all know that vegetables are good to eat but the government subsidizes corn, wheat and soy, not spinach, kale and cucumbers. Do your research, follow your hearts, do what works for you.
Hi Hannah! Thanks for stopping by from PJ affiliates. Actually my information is correct. Trust me, I do make mistakes from time to time, but Keto is actually a low carb, moderate protein, high fat diet. You can have fruit on Keto. That’s the great thing about Keto as long as it fits your macros and won’t throw you out of ketosis you can eat a variety of foods and you should! Natural and clean foods are great sources of vitamins and minerals that your bodies need to thrive and survive and while it’s a great idea to go easy on foods that will cause insulin spikes when you first start Keto once you reach your goal weight and entire maintence mode you can add more and more fruits and veggies. What many people don’t understand is glycemic load and glycemic index and that’s something I plan to start talking about here very soon! We aren’t paleo believe me my family wishes we were! Thanks again for the visit and if you’re interested in learning more about how we do Keto keep stopping by!

Shopping for the keto diet will take some time to get used to. You’ll be navigating parts of the grocery store that you may not be familiar with. You’ll also be purchasing items you’ve never cooked before. However, with planning and dedication, low carb shopping will become easier. Just remember to make a list before you visit the store and stay toward the outer aisles of the grocery store. In no time, you’ll be an experienced low carb shopper.

What fruit has no sugar or carbs


My Family went on Keto, it works for my son and his wife, but for me not so much. I was so sick for the 6 weeks I was on it, and when my heart started pounding several times a day – seriously thought I was having a heart attack, got weird rashes and my kidneys started hurting, I knew it was time to stop keto. I did loose 15lbs and have been able to still loose a few lbs on the low carb Mediterranean diet in the past 2 weeks, My son lost 25lbs and his wife lost 20lbs so far and they did not have the side effects I had.
Here’s why. All of these effects take time, but a reasonable explanation as to why the keto diet leads to rapid weight loss is due to the loss of water weight. One of the concerns with the keto diet is the loss of muscle mass and the depletion of glycogen stores. Glycogen, which stores our glucose, also stores water, so when stores are depleted, we flush out excess water. In other words, that rapid weight loss isn’t fat, it’s just water.
