But it’s worth noting that, as yet, there hasn’t been enough research into the ketogenic diet to support its use in some medical conditions – so people using the diet to treat diabetes or polycystic ovarian syndrome, should consult their doctor before trying it, as it can affect blood sugar levels. People with pancreatic or liver problems, or problems with fat metabolism should also avoid the ketogenic diet. This is because the diet is so high in fat that it puts added pressure on both organs, which are essential for fat metabolism .
Also, when you eliminate sugar and high-carb foods from your daily diet, "your body is able to heal itself and detox from the accumulated inflammation that it is constantly fighting," That means less brain fog, improved cognition and brain health. Consequently, the improved mental clarity makes it easier for you to make smart food choices, adds the nutritionist.
Bear in mind that those macronutrient ratios refer to calories from fat, protein, and carbohydrate, not actual grams of each. Protein and carbs have 4 calories per gram and fat has 9 calories per gram, so it’s actually a relatively easy task to let your fat calories pile up to keto-appropriate proportions if you consume fattier proteins and embellish your food with an extra bit of pure fat. To illustrate, if a portion of a particular food has 10 grams of protein, 10 grams of fat, and 0 grams of carbohydrate, that portion contains 130 calories, 90 from fat and 40 from protein, and is about 69.2% fat and 30.7% protein (allowing for rounding).
"It was extremely difficult," he recalls. "You spend your entire life hearing that fat makes you fat and causes heart attacks and strokes. Now, all of a sudden, you're eating 200 grams of fat per day. There is a huge psychological component to conquer before you can become successful with the keto diet. In the beginning, it's like trying to convince people 1,000 years ago that the world is in fact round, not flat."
When a person goes off the ketogenic diet and regains much of their original weight, it’s often not in the same proportions, says Kizer: Instead of regaining lean muscle, you’re likely to regain fat. “Now you’re back to your starting weight, but you no longer have the muscle mass to burn the calories that you did before,” she says. “That can have lasting effects on your resting metabolic rate, and on your weight long-term.”

This morning I calculated my keto and signed up on my fitness pal food calculator as you suggested on your website. More I read about keto more curious I get…. Last two days I ate without thinking much about portions, but today I used all your delicious recipes and made combination of meals for the day and followed my macro numbers to almost exact numbers and grams. Which meant less snacks in-between meals in my case. I also have been drinking around 120oz of water( including coffee and herbal mint tea) everyday! Can’t wait to see what happens at tomorrow morning weigh in!
Just this week, a 25,000-person study presented at the European Society of Cardiology Congress in Munich suggested that people on the lowest-carb diets had the highest risk of dying from cancer, cardiovascular conditions, and all other causes. Another study, published this month in the Lancet, also found that people who followed diets that were low in carbs and high in animal proteins had a higher risk of early death compared to those who consumed carbs in moderation. (The opposite was true, however, for low-carb dieters who opted for plant-based proteins over meat and dairy.)
The ketogenic diet—also known as "keto"—has become the latest big thing in weight-loss plans, touted recently by celebs like Jenna Jameson, Mama June, and Halle Berry. The diet involves cutting way back on carbohydrates, to 50 grams a day or less, to help the body achieve a state of ketosis, in which it has to burn fat (rather than sugar) for energy.
No matter what your diet has been before now, keto will be a big change. If you're coming from a standard American diet (SAD), your carbs will go way down, your protein may either go up or down, and your fat will go way up. If you're coming from a bodybuilding-style diet, your fat intake will jump to alarming levels, and your protein will likely drop significantly.
That’s why many health experts are concerned about people on the keto diet, especially those who try it without the guidance of a doctor or nutritionist. Doctors say that high-fat diets like this one may raise cholesterol levels, and some studies suggest that they increase the risk of diabetes. Some have even called it a “cardiologist’s nightmare.”
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)
The keto diet isn’t new, and it’s been around for nearly a century. It was originally developed to treat people with epilepsy. In the 1920s, researchers found that raised levels of ketones in the blood led to fewer epileptic seizures in patients. The keto diet is still used today to treat children with epilepsy who don’t respond well to anti-epileptic drugs.[2] 
On a ketogenic diet, your entire body switches its fuel supply to run mostly on fat, burning fat 24-7. When insulin levels become very low, fat burning can increase dramatically. It becomes easier to access your fat stores to burn them off. This is great if you’re trying to lose weight, but there are also other less obvious benefits, such as less hunger and a steady supply of energy. This may help keep you alert and focused.
