This is an adaptation period, where we’re essentially re-training our muscles and our brain to use fat as the primary fuel source instead of glucose. This adaptation can take a couple of weeks to a couple of months. As a hallmark of being keto-adapted and not just in ketosis, the skeletal muscles are able to burn fat directly for fuel, and the brain relies on the higher volume of ketones in the blood as its main source of energy.
In a state of ketosis, your body breaks fat down in the liver and converts it into ketones to be used for energy. Fat doesn't generate an insulin response, so insulin levels remain stable. This makes it much harder to store excess fat, and easier to tap into body fat stores for energy. Not only will this allow you to maintain your weight, but it will greatly encourage weight loss.
Absolutely Steve. I love ranch salad dressing, cheese, cream cheese, steak, shrimp, and some vegetables. I am making “fakery” to satisfy my sweet tooth. (Fakery is baking using almond or coconut flour instead of wheat and white flour, and Swerve sweetener instead of sugar (made with Erythritol which has no impact on GI and is good for your teeth) I am over half way to my goal already. Thank you for your article. I appreciate your dedication, knowledge and sharing with the world. (and your cute animal gifs)
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.
Sleep enough – for most people at least seven hours per night on average – and keep stress under control. Sleep deprivation and stress hormones raise blood sugar levels, slowing ketosis and weight loss a bit. Plus they make much it harder to stick to a keto diet, and resist temptations. So while handling sleep and stress will not get you into ketosis on it’s own, it’s still worth thinking about.
The ketogenic diet is super high in fat (about 80 percent of your daily calories), super low in carbohydrates (less than 5 percent of your calories), and moderate in protein (typically 15 to 20 percent of your calories). This is a pretty drastic departure from the generally recommended macronutrient distribution of 20 to 35 percent protein, 45 to 65 percent carbohydrates, and 10 to 35 percent fat.
• Standard ketogenic diet (SKD) — SKD is the type I typically recommend for most people, because it is very effective. It focuses on high consumption of healthy fats: As I explain in my book, "Fat for Fuel," you should aim for having 70 to 85 percent of your total daily calories to come from healthy fats. For your protein intake, the general rule of thumb is to follow the formula of 1 gram of protein for every kilogram of your lean body mass.
It truly depends from person to person. While some may be able to stay in ketosis while consuming 80 grams of carbs, others may not be so lucky. Quite a lot of people within the population can go quite high in their carbohydrate consumption and stay in ketosis, granted they have no blood sugar dysregulation. The longer you have followed the keto diet, the more your metabolism remains in ketosis after a higher carb consumption.
• Fighting inflammation — The human body can use both sugar and fat as fuel sources. However, the latter is preferred because it is a cleaner, healthier fuel that releases far fewer reactive oxygen species (ROS) and secondary free radicals. By eliminating sugar from your daily food consumption, you're decreasing your risk of developing chronic inflammation throughout your body.
It feels like everyone is talking about the keto diet — the high-fat, low-carb eating plan that promises to turn your body into a fat-burning machine. For that reason, keto has surged in popularity over the past year as a lose-weight-fast strategy. Thank Hollywood A-listers and professional athletes like Halle Berry, Adriana Lima, and Tim Tebow who’ve publicly touted the diet’s benefits, from shedding weight to slowing down aging. Here’s everything you need to know about going keto — and how to do it the Bulletproof way.
I love your site but your note about Diabetic Ketoacidosis is completely wrong. DKA is not something that happens because your body produces too many ketones. It is something that happens when your body produces too many ketones, and you don’t have any insulin in your system. As long as a Type 1 Diabetic takes insulin they will NOT go into DKA. Especially since DKA requires high ketones, high sugars, and low insulin.
Most alcoholic beverages don’t list the ingredients or nutritional information on the label, so be prepared and check your favorite drinks online so you know your limits beforehand. Most apps and trackers list many types of alcohol in their database, and this is the easiest way to be sure of what you’re drinking. Be warned, when you’re in ketosis your alcohol tolerance will go down, so you might not want to drink as much as you might be used to.
Probably, and there are a few reasons why, Keatley says. For starters, people usually reduce their daily caloric intake to about 1,500 calories a day because healthy fats and lean proteins make you feel fuller sooner—and for a longer period of time. And then there’s the fact that it takes more energy to process and burn fat and protein than carbs, so you're burning slightly more calories than you did before. Over time, this can lead to weight loss.
The biggest challenge with vegan and vegetarian diets is getting enough protein. These diets are traditionally lower in protein anyway, since they exclude the concentrated proteins in animal flesh. These individuals may want to include plant-based protein powders and shakes. Be wary of the ingredients, since these powders may contain various sugars that aren’t compatible with a ketogenic diet.
Taking your first step into the ketogenic diet is an exciting phase for your health. But before coming up with an actual ketogenic diet food list, it's important to first take a look at what you're eating now and take out anything that's unhealthy. This means that you have to remove sugars, grains, starches and packaged and processed foods from your diet. Basically, anything that won't add to your new eating regimen has to go. This is what I call a "pantry sweep."
It comes down to simple mathematics. In order to stay in ketosis, you need to eat a very very low number of carbs. And if you eat too much protein, this can actually knock you out of ketosis as well. Therefore, if you’re eating almost no carbs, and you are eating moderate amounts of protein, the ONLY remaining macronutrient you can consume to fill you up each day would be fat. Add in that consuming fat allows you to stay in ketosis, and you are consuming a high fat, medium protein, low carb diet.
To prevent side effects such as the keto flu, begin transitioning your meal plan gradually. Start by understanding how many carbohydrates you take in most days. Then begin slowly reducing your carbohydrate intake over a period of a few weeks while gradually increasing your intake of dietary fat to keep your calories the same. You should also make sure to seek guidance from a professional to make sure this plan works best for you and your health goals. “See a dietitian and adapt the diet to fit your long-term needs,” Spano recommends.
When it comes to weight loss — a big possible draw of the plan for many individuals — the benefits of the ketogenic diet may not be much different from any other diet plan. “There is no magical weight loss benefit that can be achieved from this diet,” says Spano. “The ketogenic diet may help weight loss in the same way other diets help — by restricting food choices so you eat fewer calories.”
Although fat is the centerpiece of any keto diet, that doesn't mean you should be subsisting on butter-topped steaks, says Kristen Mancinelli, RD, author of The Ketogenic Diet. “A big misconception is that you should just put meat at the center of your plate and add more fat on top,” she says. You also shouldn't be relying on fatty meats to hit your fat quota, she adds.
Basically, when you have alcohol in your body, the first thing that will be burnt is the alcohol. Only then, can your body begin to burn carbohydrates, and ultimately move on to fat-burning mode. By consuming small amounts of alcohol, the alcohol will be burnt quite fast and then move on to burning carbohydrates. The biggest tip here is to only include alcohol in your diet once your body is fully adapted to a high-fat diet.

You’re transitioning. Your body is equipped to process a high intake of carbs and a lower intake of fat. Your body needs to create enzymes to be able to do this. In the transitional period, the brain may run low on energy which can lead to grogginess, nausea, and headaches. If you’re having a large problem with this, you can choose to reduce carb intake gradually.
Wondering how many carb foods you can eat and still be “in ketosis”? The traditional ketogenic diet created for those with epilepsy consisted of getting about 75 percent of calories from sources of fat (such as oils or fattier cuts of meat), 5 percent from carbohydrates and 20 percent from protein. For most people a less strict ketogenic diet (what I call a “modified keto diet”) can still help promote weight loss in a safe, and often very fast, way.
The current hypothesis is that the brain functions differently on ketones than on glucose, and this is what causes certain brains to reduce epileptic seizures. I would then also hypothesize that certain people who feel that “brain fog” lifted on ketosis is due to either placebo effect OR their brain actually functioning differently on ketones vs glucose.
