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)
The reason you eat a balanced diet, which includes fruits, vegetables, dairy, protein, grains, legumes, nuts, and seeds, is to get a variety of nutrients your body needs to stay healthy. You can do so on a lower calorie diet *and* successfully lose weight. However, on the keto diet, grains, legumes, and fruit are pretty much eliminated (berries, watermelon, and apples are allowed sparingly). These food groups provide a ton of nutrients including fiber, phytonutrients, and antioxidants like vitamins A and C. Keto dieters are also known to have constipation because of the lack of fiber in their diet. (FYI, here are the supplements you should take if you're on the keto diet.)

The main objective of the ketogenic diet is to get the body to start relying primarily on fat for energy. In general, our bodies are predominantly fueled by glucose (also known as blood sugar), which we get from carb-rich foods (bread, cereal, pasta, rice, etc.). The digestive tract breaks these foods down into glucose so it can be converted into adenosine triphosphate (ATP), which is the chemical our bodies can use for energy. But when the body is deprived of carby delights, it finds other ways to make energy, and one way is a process called ketogenesis. During ketogenesis, the body turns to fat for energy; the liver breaks it down into ketones, making it a usable energy source, Amy M. Goss, Ph.D., assistant professor at the University of Alabama at Birmingham’s Nutrition Obesity Research Center, explains to SELF via email.
The ketogenic diet achieved national media exposure in the US in October 1994, when NBC's Dateline television programme reported the case of Charlie Abrahams, son of Hollywood producer Jim Abrahams. The two-year-old suffered from epilepsy that had remained uncontrolled by mainstream and alternative therapies. Abrahams discovered a reference to the ketogenic diet in an epilepsy guide for parents and brought Charlie to John M. Freeman at Johns Hopkins Hospital, which had continued to offer the therapy. Under the diet, Charlie's epilepsy was rapidly controlled and his developmental progress resumed. This inspired Abrahams to create the Charlie Foundation to promote the diet and fund research.[10] A multicentre prospective study began in 1994, the results were presented to the American Epilepsy Society in 1996 and were published[17] in 1998. There followed an explosion of scientific interest in the diet. In 1997, Abrahams produced a TV movie, ...First Do No Harm, starring Meryl Streep, in which a young boy's intractable epilepsy is successfully treated by the ketogenic diet.[1]
Breakfast was our favorite weekend treat. We'd always go out to our diner and order all American breakfast (eggs, bacon, potatoes) and shared an order of waffles or french toast. Now, partially to save money and mostly because you can't really trust most restaurants not to add hidden carbs in things, we cook at home. Now I can't believe we used to eat all of this tasty food AND an extra stack of extras.
One downside to a ketogenic diet for weight loss is the difficulty maintaining it. “Studies show that weight loss results from being on a low-carb diet for more than 12 months tend to be the same as being on a normal, healthy diet,” says Mattinson. While you may be eating more satiating fats (like peanut butter, regular butter, or avocado), you’re also way more limited in what’s allowed on the diet, which can make everyday situations, like eating dinner with family or going out with friends, far more difficult. Because people often find it tough to sustain, it’s easy to rely on it as a short-term diet rather than a long-term lifestyle.
