Because the main tenet of the keto diet is counting and cutting carbs ” a commonly used way to control blood sugar ” this eating approach has become increasingly popular among people with type 2 diabetes who are looking to lower their A1C, which is the two- to three-month average measurement of blood sugar levels. Indeed, research suggests this diet may lead to fast weight loss and potentially lower blood sugar for people with the disease. (13)
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 œcarbs 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).
One of the most common side effects of starting the ketogenic diet is the œketo flu. This term describes the often unpleasant, fatigue-inducing symptoms that occur as the body adjusts from a high-carbohydrate to a low-carbohydrate diet. During the keto flu, the body's stored glucose begins depleting, and the body starts adapting to producing and utilizing ketones as energy. (2)

Once ketone levels in the blood rise to a certain point, you officially enter into a state of ketosis. This state results in fairly rapid and consistent weight loss until you reach a healthier (and stable) body weight. Overall, people enter into ketosis at different rates, usually after 3“4 days of fasting or following a very low-carbohydrate diet (20 grams of net carbs or less) that forces the need for an alternative energy source. (3)
For some, ketosis can cause more negative than positive side effects. Dorena Rode, a 52-year-old author, and speaker from Occidental, California, tried the diet for a month and experienced heart palpitations and dizziness. Unlike Drew, Rode says her cholesterol increased from 192 to 250 mg/dL after she introduced more fat into her diet. (Less than 200 mg/dL is considered desirable, while anything over 240 mg/dL is considered high.)
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.
Use our keto calculator to calculate the exact macros you should be eating. Remember, substituting more fat for carbs or protein is almost always ok. In fact, if you're worried about losing muscle mass because of decreased protein consumption, you may not need to worry. There has been evidence that while in a state of ketosis your body actually maintains protein better than in a standard diet.
Not necessarily. It ultimately depends on you. SOme people may thrive by regularly counting calories, while others see counting calories as something œboring. The key here, if you do not want to count calories, is to structure your plate in order to guarantee you are consuming enough fat. Just make sure that in every meal you are eating no more than a palm-full of protein, try to increase the amount of fat in your diet, and try to decrease the amount of carbohydrates.

Many people also experience cramping, notably in the feet and legs. Because of this, you'll want to consume extra electrolytes any time you are on a ketogenic plan. People who suffer with these symptoms refer to them as the Keto-Flu, and while it isn't like the real flu, the symptoms can knock you down until you get your electrolytes back in balance.
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.
First, let's start with the fact that most of the food in your cabinets just won't work anymore. They're not keto. Period. Lock them up, throw them out, donate them to a neighbor “ whatever you have to do to get them out of the house. In the first week, when you're craving carbohydrates, these foods will be the death of your ketogenic diet. Purge your pantry of carbohydrate foods!
The keto diet is currently being used as a safe and effective addition to the treatment of several types of cancer and can help slow tumor growth. As an example, we'd like to point to a promising study showed the intracerebral growth of the CT-2A & U87-MG tumors (related to malignant brain cancer) is significantly decreased by about 65% and 35% (27).
On a œstrict (standard) keto diet, fats typically provides about 70 percent to 80 percent of total daily calories, protein about 15 percent to 20 percent, and carbohydrates just around 5 percent. However, a more œmoderate approach to the keto diet is also a good option for many people that can allow for an easier transition into very low-carb eating and more flexibility (more on this type of plan below).
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!
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]
Those issues can be part of what's known as the œketo 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.

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.
Can't you take ketone supplements? No. While it is possible to elevate ketones by taking them, œwithout the low-carb stimulus, there is no net increase in ketone production, no decrease in insulin, and no net increase in fat oxidation, says Volek. Don't trust trainers or œbody hackers who say you can induce ketosis quickly without changing your diet.
This means that if you have risk factors for heart disease ” such as elevated cholesterol levels, high blood pressure (hypertension), or a strong family history of the disease ” you should use caution when following this diet. The diet's heavy reliance on fat, especially saturated fat, can elevate cholesterol levels, further increasing your chances of developing heart disease in the future. (7)
You're absolutely gorgeous, and I am looking forward to losing more than 40 lbs. also. I'm on my third week and feel like I hit a wall. I was waking up in the morning feeling my tummy a little flatter, some clothing a bit looser, etc. and now don't feel like that. So, I looked up foods again, and I don't think I was eating enough fat. Thank you for a simple version and grocery list of keto foods. It helps a lot! I hope to visit again soon and report double digit weight loss! Blessings!
The Atkins diet, on the other hand, is solely focused on weight loss. There is no restriction on artificial sweeteners or manufactured foods, as long as the foods consumed fit the Atkins prescribed ratios. There are four phases to the Atkins diet. The first phase is the most strict, designed to get you into ketosis. The second phase is a tolerance testing phase, where you add more foods to see how many grams of carbohydrate you can still eat and lose weight. The third phase is more generous with carbs, and the fourth phase is the most generous, and it's in either the third or fourth phase that most people find a good maintenance level.
What is the keto diet? Rather than relying on counting calories, limiting portion sizes, resorting to extreme exercise or requiring lots of willpower (even in the face of drastically low energy levels), the ketogenic, low-carb diet takes an entirely different approach to weight loss and health improvements. It works because it changes the very œfuel source that the body uses to stay energized: namely, from burning glucose (or sugar) to dietary fat, courtesy of keto recipes and the ketogenic diet food list items, including high-fat, low-carb diet foods.
Check the nutrition labels on all your products to see if they're high in carbs. There are hidden carbs in the unlikeliest of places (like ketchup and canned soups). Try to avoid buying products with dozens of incomprehensible ingredients. Less is usually healthier.Always check the serving sizes against the carb counts. Manufacturers can sometimes recommend inconceivably small serving sizes to seemingly reduce calorie and carb numbers.
That said, I think the biggest changes are the result of me dropping the sugars and breads. Tracking my eating and being more conscious about my foods has made a difference. I definitely plan to keep on this track for a while and slowly work towards a fuller keto-adapted diet/body. I'm not going with the œall-in that some recommend, cutting out all artificial sweeteners and such, though I have limited them. I'm not really tempted to indulge in the sweets that have been tempting in the past.
Fats are great if you want to add flavor and texture to your meals, and will help you feel full. Some people believe swear by coconut oil, and whether or not the claimed health benefits are actually present, it's one of the fats that you might want to add to your diet. Butter is an excellent choice, as is ghee (Indian clarified butter). Duck fat is highly prized. Avocado oil is a great choice when making dressings or sauces, as it's liquid at room temperature and has a mild flavor. The fats and oils listed here are primarily saturated, and they are the least likely to go rancid and produce free radicals and inflammation in the body (5, 6).
A ketogenic diet helps control blood sugar levels. It is excellent for managing type 2 diabetes, sometimes even leading to complete reversal of the disease. This has been proven in studies. It makes perfect sense since keto lowers blood-sugar levels, reduces the need of medications and reduces the potentially negative impact of high insulin levels.
Here's the Knowledge Stage analogy: Say we are hungry and want to go out to eat. It wouldn't make much sense to sprint to the nearest restaurant, right? Wouldn't we be better served to take the few minutes to learn about what's available, and then make a plan? Yes, we would take the time to Yelp or ask a friend for some knowledge and use that information to decide where we want to go.
The ketogenic diet is based on the principle that by depleting the body of carbohydrates, which are its primary source of energy, you can force the body to burn fat for fuel, thereby maximizing weight loss. When you consume foods that contain carbohydrates, the body converts those carbohydrates into glucose, or blood sugar, which it then uses for energy. (1)
It can be very difficult to obtain some of the very high levels of blood ketones on this table - especially as you become "fat adapted" or "keto adapted" or whatever you want to call it. Once your body is efficient at using ketones, it makes only what it needs. Beginners may see very high levels of ketones, and then they see them drop off. This isn't because you are making a mistake and are out of ketosis - your body is no longer overproducing them.

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.
Protein: Keep in mind that keto is high-fat, and not high-protein, so you don't need to eat very much meat. Too much protein turns into glucose in the body, making it harder to stay in ketosis. Stick to fatty cuts of grass-fed, pasture-raised, or wild meat, and wild-caught fish. Red meats, offal/organ meats, pork, eggs (preferably pastured), fish, shellfish, and whey protein concentrate.
The macronutrient ratios for the keto diet can range between 65-90% fat, 5-25% protein, 4-10% carbohydrates depending on the person. Those are actually pretty large ranges, so they deserve an explanation. There are a lot of details that come into play to calculate your macros for ketosis including your current weight, target weight, exercise frequency, and more.
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.

Paleo and keto can overlap, though there are some major differences in the core of each way of eating. The Paleo diet focuses on whole, natural foods that would have been available as food to our paleolithic ancestors. If it could have been hunted or foraged, then it would have been eaten. Some people on a Paleo plan also focus on what would have been growing in season, and in a certain region of the world for their genetic ancestors. Carbs are overall allowed in a Paleo plan, but they would come from whole foods like potatoes, sweet potatoes, fruits, honey, and other unprocessed sources.

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.
