46 INSIDER September/October 2017 Ketosis is a metabolic state in which most of the body's energy supply comes from ketones (sometimes known as "fractured fats") found in blood plasma. This is different to the state of glycolysis in which plasma glucose (carbohydrates) provides most of the body's energy needs. Despite rumblings around the internet, ketosis is a natural state for the body to be in; it is a normal metabolic state during fasting or when a person is on a strict low-carb diet, known as a "ketogenic diet." The nuts and bolts of a ketogenic diet were designed in 1924 by Dr. Russell Wilder at the Mayo Clinic as a potential cure for epilepsy. The idea behind a ketogenic diet is that the dieter will obtain most of his or her daily calories from fat, fewer from protein, and even fewer from carbohydrates. When a person consumes fewer than 50 grams of carbohydrates per day, the human body will eventually run out of fuel (plasma glucose) that it can use immediately. This process typically takes 72 hours. Next, the body will start to break down fat and protein for energy in lieu of carbohydrates— this can assist in losing weight. This state of using fats instead of carbohydrates for the body's predominant energy source is called "ketosis." A ketogenic diet may help some people lose more weight in the fi rst three to six months of heavy dieting than many other types of diets. This may be because it takes more calories to change fat into energy than it does to change carbohydrates into energy. It's also possible a high-fat, moderate- protein diet makes people feel more satisfi ed and full, so they eat fewer calories, but that hasn't been conclusively proven, and more research is needed. When people talk about ketogenic dieting, a term than gets thrown around a lot is "macros." The term macros is short for macronutrients, which are the energy-providing components of food. Macronutrients include carbohydrate, protein and fat—basically, the stuff where all calories come from. While opinions vary greatly as to what macro profi le is best to optimize weight loss during a ketogenic diet, I believe the best macro profi le for most people during this type of dieting is: 70 to 75 percent of calories from fat (or even more, many people strive for a full 80 percent), 15 to 25 percent of calories from protein, and 5 to 10 percent of calories from carbs. Being in ketosis or undertaking a ketogenic diet by itself is not enough to lose weight. The fi rst law of thermodynamics (conservation of energy) would be violated if it did. In order to lose weight while in ketosis/using a ketogenic diet (or on any diet for that matter), a person absolutely must burn more calories than they ingest. People can meet this goal by reducing caloric intake, burning more calories from healthy exercise or, ideally, a combination of both. Consumers who are trying to induce and/or maintain ketosis should completely avoid eating foods that contain moderate- to-high amounts of carbohydrates. This includes grains, even whole meal grains such as wheat, rye, oats, corn, barley, millet, bulgur, sorghum, rice, amaranth, buckwheat and sprouted grains. It also means avoiding quinoa and white potatoes. Additionally, any foods that are made from these grains such as pasta, bread, pizza, cookies, crackers, etc., and sugar/sweets (e.g., table sugar, high-fructose corn syrup, agave syrup, ice cream, cakes, sweet puddings and sugary soft-drinks) should be avoided to induce and properly maintain ketosis. Also, all tropical fruits (e.g., pineapple, mango, banana, papaya, etc.) and other high-carbohydrate containing fruits (e.g., tangerine, grapes, etc.) need to be avoided. When undertaking a ketogenic diet, consumers need to monitor if they are or are not in ketosis. The average person has two methods to use at home to make the determination: urine testing and blood detection. It is important to consider that in order to achieve and maintain ketosis, this diet must be a long-term lifestyle change followed by a specifi c, detailed eating regimen to maintain weight loss over time. Ketogenic diets are good for almost anyone looking to lose weight rapidly, increase mental focus, feel more energized and desiring to better control hunger. But no diet should substitute for the advice and medical treatment of a physician or other health care provider.
