The Ketogenic Diet is unlike any other diet in the world in that it utilizes a high fat, minimal carbohydrate and moderate protein system in order to reset your body’s ability to burn unwanted, stored fat. By restricting carbohydrates that are converted into glucose, you begin the journey to re-program your metabolism to start burning stored fats for fuel and energy instead of first burning beneficial glycogen that is stored in your muscles.
Hi Lauren, I just started this diet. Any tips for beginning? I am not sure I am taking in enough throughout the day. I snack on cheese and red grapes, raspberries throughout the day. I have a protein shake for breakfast and lunch. and then this evening I am having a chicken salad with avocado and romaine. Like I said I don’t think I am taking in enough throughout the day.
A related clinical diet for drug-resistant epilepsy is called the medium-chain triglyceride ketogenic diet, in which MCT oil is extensively used because it’s more ketogenic than long-chain triglycerides. (13a) Another dietary therapy for epilepsy called Low Glycemic Index Treatment (LGIT) was developed in 2002 as an alternative to the ketogenic diet. LGIT monitors the total amount of carbohydrates consumed daily, and focuses on carbohydrates that have a low glycemic index.) (13b)
Your lean body mass is your total body weight minus your fat. For example, if you currently weigh 180 lbs (81.65 kg) and your body fat is at 30%, your lean body mass is 126 lbs (57.16 kg). In order to obtain the amount of protein you need to eat daily, you need to multiply 126 per 0.6 to 1.2, and you’ll get a range of 76 to 151 g protein/day. 75.6 g would be the minimum amount you need in order to maintain your bodily functions and muscle mass.
Depending on how you choose your fats, the keto diet can contain an abundance of saturated fat, which raises levels of dangerous LDL cholesterol and causes atherosclerosis, the buildup of fats and cholesterol in the arteries. If you decide to go keto, have a doctor monitor your cholesterol levels monthly to ensure you remain within a healthy range.

A “moderate keto diet” is an option that can still encourage substantial weight loss and other improvements in symptoms. A moderate keto diet includes more foods with carbs and, therefore, more fiber too. Carbs are usually increased to about 30–50 net grams per day, which means foods like more high-fiber veggies, some fruit or some starchy veggies can also be included.
Hi Emily, I was also really nervous about the amount of fat when I first started too! Just trust it, give it a couple of weeks to work its magic and then you will definitely feel more comfortable! I actually used a couple of online calculators for macros and took the average of what they all said. When starting keto, remember your net carbs should be under 20 grams, so use that as a guideline when calculating the rest of your macros. Let me know if you need anything else!
The removal of many grains and fruits with such a large emphasis on fats can bring about its own set of side effects. “If not done properly — with most of your carbohydrates coming from fiber-rich vegetables — you may not be getting enough fiber, which can lead to constipation,” says Chris Mohr, PhD, RD, a sports dietitian based in Louisville, Kentucky, and co-owner of MohrResults.com.

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.
This process of burning fat provides more benefits than simply helping us to shed extra weight — it also helps control the release of hormones like insulin, which plays a role in development of diabetes and other health problems. When we eat carbohydrates, insulin is released as a reaction to elevated blood glucose (an increase in sugar circulating in our blood) and insulin levels rise. Insulin is a “storage hormone” that signals cells to store as much available energy as possible, initially as glycogen (aka stored carbohydrates in our muscles) and then as body fat.
The classic ketogenic diet is a very low-carb diet plan that was originally designed in the 1920s for patients with epilepsy by researchers working at Johns Hopkins Medical Center. (1) Researchers found that fasting — avoiding consumption of all foods for a brief period of time (such as with intermittent fasting), including those that provide carbohydrates — helped reduce the amount of seizures patients suffered, in addition to having other positive effects on body fat, blood sugar, cholesterol and hunger levels.

Some people just cut out the bulk of carbohydrates from major sources like breads, pastas, and sodas, and these people are on a Low Carbohydrate plan. There isn’t anything particularly strict about it, it’s more about being mindful of overall carb intake, often without tracking. This can be a good place to test the waters of a keto diet, though many people on this kind of plan never get into ketosis without further restriction.
Although a standard ketogenic diet is even more restrictive in terms of carb intake, a “moderate keto diet” (just as some folks have followed a modified Atkins diet) is another option that will very likely still be able to provide substantial weight loss results and other improvements in symptoms. Including slightly more carbs can be very useful for maintenance, allow for more flexibility, provide a higher fiber intake, and overall may feel more sustainable long term socially and psychologically.
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 “fuel 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.
• Cyclic ketogenic diet (CKD) — Whereas TKD is focused on fitness enthusiasts, CKD is focused more on athletes and bodybuilders. In CKD, you cycle between a normal ketogenic diet, and a short period of high carb consumption or "re-feeds."8 The idea here is to take advantage of the carbohydrates to replenish the glycogen lost from your muscles during athletic activity or working out.9
The biggest shifts in your daily habits will be how you food shop and how you cook, and recipes that are ketogenic need to be followed rather than just low-carb. You will require the healthy fats in order to get into ketosis and have enough energy without the carbs. And you will be considerably more energetic and healthier when cooking your own keto-friendly food rather than buying supposedly keto foods off the shelf. So visit my page on keto recipes as well as keto snacks (including fat bombs!), and get started on a ketogenic meal plan!

The biggest draw for me is how many of those who’ve tried it say they don’t get hungry. The possibility of that blows my mind, as someone who’s used to any sort of calorie restriction meaning hours of feeling hungry every day. It’s tantalizing enough that I at least want to try. And what have I got to lose, right? I’m already morbidly obese; it’s hard to imagine screwing this up so bad it makes that worse.
