But what does the science say? Results are mixed. In one Spanish study of 20 obese adults, participants were put on a low-calorie keto diet and lost an average of 40 pounds over four months. Another small experiment had a similar outcome. In a six-month Experimental & Clinical Cardiology study of 83 obese adults, those on the keto diet lost an average of 33 pounds, while lowering their bad (LDL) cholesterol levels and increasing their good (HDL) cholesterol.
After the initial transition period (often referred to as the fat-adaptation or keto-adaptation period), most people find they gain a ton of mental and physical energy. They don’t have energy crashes in the afternoons and they often sleep a bit less but wake up feeling refreshed. They also tend to eat less because they don’t feel hungry or have cravings.
It’s important to remember that the goal of any dietary change is to promote a healthy lifestyle, so make sure to select a meal plan you can envision yourself following long term. If you know you will not be able to comply with such stringent carbohydrate restrictions for years to come, the ketogenic diet is most likely not the right choice for you.
Clinical improvement was observed in Alzheimer’s patients fed a ketogenic diet, and this was marked by improved mitochondrial function. (14a) In fact, a European Journal of Clinical Nutrition study pointed to emerging data that suggested the therapeutic use of ketogenic diets for multiple neurological disorders beyond epilepsy and Alzheimer’s, including headaches, neurotrauma, Parkinson’s disease, sleep disorders, brain cancer, autism and multiple sclerosis.

This book is split into 3 parts: The Ketogenic Lifestyle, The 14-day Meal Plan, and the recipes. Before this book, I really didn't fully understand what a Ketogenic Diet was. Chapter 1 defines it for me in 4 words, Low-Carb, High-Fat. This diet promotes fresh whole foods and healthy fats & oils, and cuts out processed, chemically treated foods. It also tells you that when you start a Keto Diet, you'll most likely experience the Keto-Flu!

Protein will induce an insulin response in the body, if consumed in high amounts. The most intuitive way to start a keto diet for most people is by removing all of the carbs they have been eating. Typically people will replace those calories by increasing their lean meat consumption. That's a recipe for disaster! Keeping protein moderate is an often overlooked, but very important part of a keto diet. Most people need around 0.6g to 1.0g of protein per pound of lean body mass.
• Multiple Sclerosis: In a small 2016 study, patients with multiple sclerosis (MS) were put on a ketogenic diet. After six months, they reported improved quality of life, as well as physical and mental health improvements. Before doctors or researchers can make a connection between keto and MS, they need bigger sample sizes and more thorough research. Still, the preliminary findings are exciting.
• Water Loss: There is some evidence that higher-protein diets like the keto diet do have some weight-loss benefits, partially because both fat and protein are satiating so you don't feel hungry, but also because of the loss in glycogen stores. Glycogen is the body's glucose storage that is bound up with water, so when we deplete the glycogen, you also deplete your water storage. Lose a ton of water, and you're going to drop weight fast.
From the early understanding of the keto research and literature, it looks like we're just scratching the surface understanding some of the potential therapeutic roles of the keto diet. While it's unclear if it's any better or worse than any other diet for weight loss, the reality is that there is no one-size-fits-all model for diets. This doesn't even consider that weight-loss diets, in general, don't really work. While researchers can't agree on a specific statistic, it's commonly accepted that the vast majority of dieters will regain the weight lost (and often pack on extra pounds, as well). The long-term outcome of the keto diet is likely to be no different, especially given how challenging and restrictive it is to maintain.
Since last week, I no longer experience consistent headaches, fatigue, bloating, gas, headaches, fatigue, bloating, gas, headaches..yeah, you get it (repetition intentional). Oh, and chronic constipation? What just happened here? It’s going bye-bye. Not a Celiac; gluten-sensitive? I don’t know but right now, honestly, I don’t care. After the gone-with-the-sh*t last week, I’m staying away from those “carbs” and the wreck they havoc’d on my system for years (and made me paranoid I had a brain tumour which the doctor ruled out).
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 >
The information in the first section was great, but the recipes were not as helpful as I had hoped. The ingredients are very expensive - I spent $130 shopping for just the first three days of meals and that didn't include the leg of lamb, which I skipped. Also, as a working mom, I would consider the amount of kitchen time as extreme. As an example, Day One includes a one-hour baking project for breakfast, followed by deviled eggs with bacon and avocado as a mid-morning snack, followed by a cooked chicken lunch, then a smoothie mid-afternoon snack, and a leg of lamb dinner with a side. Again, that's just the first day. Section 1 was great and I learned a great deal about keto lifestyle and issues. I would love the author to revise the meal plan and recipe sections to limit each day to no more than 90 minutes in the kitchen including prepping foods like boiling eggs, frying bacon, or cooking chicken which aren't currently included in her recipes times.
It’s easy to get caught up on the “low-carb” part of the diet and not give enough attention to the “high-fat” part. Fat is what makes you full, gives you energy (when in ketosis), and makes food taste delicious. For most people this figure should be north of 70 percent of daily calories. Keep carbs under 20g, hit your protein goal, and eat fat until you’re full.
Totally agree that it’s not something for everyone, though. Even one of the authors I read said he sometimes sneaks a french fry or a bite of cheesecake/ice cream, though he’s able to stop after just a little bit and it doesn’t throw him off horribly. Of course, that’s not license to eat junk all the time, but it does mean that once you’re well-adapted, you can sometimes indulge.
Certain studies suggest that ketogenic diets may “starve” cancer cells. A highly processed, pro-inflammatory, low-nutrient diet can feed cancer cells causing them to proliferate. What’s the connection between a high-sugar diet and cancer? The regular cells found in our bodies are able to use fat for energy, but it’s believed that cancer cells cannot metabolically shift to use fat rather than glucose. (11)
Beverages: It’s common to become dehydrated on the keto diet. Your insulin levels drop when you restrict carbs, and low insulin makes it harder for your body to retain sodium and water. Drink plenty of plain water, and sip on bone broth to replenish electrolytes, especially during the first couple of weeks when your body is adjusting to the new diet.
This was a great read , Steve, thanks! I’m 19 days in but forever educating myself. Wish I’d been more prepared for the keto flu cos’ that hit me HARD! Out the other side now though and hoping to see some improvements in my cycling endurance and less reliance on the gels and goos! I’ll also be doing lots of HIIT for some racing that I’ll be doing this winter (in the UK) so looking forward to experimenting with that! As a former (and maybe still current) sugar lover, the dessert tips were especially useful. Thanks again!
Basically, fat within your blood travels as lipoproteins, along with cholesterol, proteins, and phospholipids. In order for an artery to be “clogged”, there needs to be a small tear in its inner wall first. These tears can be due to stress, smoking, a highly-processed diet, etc. In order for the walls to be repaired and thus prevent “clogging”, Vitamin E must be used. Vitamin E, being a fat-soluble vitamin, requires fat in order to be available for your body to use. Therefore, the consumption of fat can help your arteries self-heal and thus prevent “clogging”.
Note: Are you a vegetarian or vegan and want to go on a ketogenic diet? It’s still possible! Just keep in mind that the dietary restrictions can sometimes be a little bit intense. Make sure to plan ahead and prepare to aid your success. To help out, we’ve published articles (with 7 day meal plans included) for both the vegetarian ketogenic diet and the vegan ketogenic diet.
A: The most common ways to track your carbs is through MyFitnessPal and their mobile app. You cannot track net carbs on the app, although you can track your total carb intake and your total fiber intake. To get your net carbs, just subtract your total fiber intake from your total carb intake. I have written an article on How to Track Carbs on MyFitnessPal.
Many books could be written on this very subject, and undoubtedly they have been. There are many answers, and they all depend on context. Lots of variables impact how well, and how consistently we lose weight. How much sleep do we get each night, and how restful is that sleep? What micronutrients are we not getting enough of? How much water are we drinking? How much are we exercising?
5) By now you should know both where you are and where you want to be. Those are the first steps. Now it’s time to start planning your meals. You can use these food lists to help you figure out what kinds of foods you should be eating. Remember this is not a diet plan that has an end date. This is a lifestyle change that you will pass on to your children.
I’m honestly a little skeptical about it the idea of keto permanently. My brief glance at the literature seems to imply that it can have side effects of kidney stones, skeletal fractures, and slow the growth rate of children, but that was a study on kids with epilepsy (which it treated very effectively), so who knows how that applies to adults. And the other studies I found dealt with overweight and obese subjects, so it may be hard to find something on the long term effects on otherwise healthy adults.
