Ketogenic diets allow you to eat real foods in the form of natural fats and protein (meat, fish, poultry) but severely restrict the amount of carbohydrates (sugars and starches) you are allowed each day.
On a “normal” American diet, carbohydrate intake is high (about 40-60% of calories) while fat intake, and especially saturated fat, is limited. Diets high in carbohydrate have the effect of elevating blood sugar and a hormone called insulin over time. The chronically higher levels of blood sugar and insulin result in a condition called insulin resistance or metabolic syndrome which can result in constant hunger, weight gain and a long list of disease outcomes.
In contrast, carbohydrate intake on a keto diet is only about 2-4% of calories. When carb intake is low, meals are delicious and satiating. Hunger goes away, and more importantly, this dietary change has some powerful and beneficial metabolic effects on the human body, in part because it lowers blood sugar and insulin levels. On this website, I’ll talk about how the diet works, and share details on the correct implementation of the diet. The bottom line here is that you can increase your energy and improve your health simply by changing the way you eat.
When carbohydrates (sugar and starch) are digested, they are broken down into blood sugar (glucose) in the body. More carbohydrate intake results in higher blood sugar. If we reduce carb intake and instead eat more fat and protein, it results in a switch in metabolic pathways from using sugar as a primary fuel to burning stored and dietary fat as a primary fuel.
As more fat is burned, some of it is converted in ketone bodies. As blood glucose and insulin levels drop and ketone levels rise, muscle tissue, including the heart, use the available fatty acids in the bloodstream as fuel and the brain begins using ketones as an energy source. Being in this metabolic state of "nutritional ketosis" (blood sugar is low and ketone levels are moderate) has some powerful benefits. There is strong research evidence that low carb, high fat metabolic diets are effective for treating the following medical conditions:
Cancer: the current research on metabolic cancer treatments using a keto diet are extremely promising. The keto diet for cancer therapy is somewhat different than the treatment for other illnesses, and is discussed in detail in my e-Book Fight Cancer with a Ketogenic Diet, which is based on the work of both Dr. Thomas Seyfried and Dr. Dominic D'Agostino. The main idea behind the use of a ketogenic diet to treat cancer is to starve the cancer cells of the glucose and other fuels they need to survive, and provide support for the normal mitochondrial respiration processes in healthy tissues. The huge advantage of this treatment protocol is that it is non-toxic to the rest of the body, and in "wait and see" cases, can provide an huge health support advantage to the patient.
The new third edition of Fight Cancer with a Ketogenic Diet is also available in paperback form on Amazon.
Diabetes: The current diabetes treatment advice is to eat 45-65% of calories from carbohydrate. Since carbohydrate is the prime driver of higher blood sugar, this advice is detrimental to diabetic health because it results in blood sugar spikes and crashes, which in turn causes a greater need for medication and insulin. Those high blood sugars also result in the complications of diabetes. In contrast, a ketogenic diet reduces and in many cases, eliminates the need for diabetic medications and lowers the number of insulin units needed to manage blood sugar. For people with Type 2 diabetes, ketogenic diets remove the trigger (carbohydrate intake) and reverse the underlying insulin resistance which causes the disease. As a result, long term complications are reversed or avoided. Learn more in our "Conquer Type 2 Diabetes e-Book or click on the book cover at left.
Type 1 Diabetes: Lowering carb intake and increasing fat intake is also beneficial for people with Type 1 diabetes and can help lower the number and severity of hypoglycemic episodes, reduce HbA1c scores and minimize future complications. Learn more in "The Ketogenic Diet for Type 1 Diabetes e-Book" or click on the book cover at right. These benefits are also possible for children with Type 1 and their parents should know that they have options.
Both books are also available in paperback format on Amazon.com.
Weight Loss: Low carb, high fat keto diets have been proven in study after study as the best diet for weight loss because the diet works with your biochemistry instead of against it. To help readers implement the diet correctly, check out our web app My Keto Plan, a tool designed by Ellen Davis and Austin Voss to help people achieve fast, healthy weight loss with a ketogenic diet. It's a great teaching tool for understanding how to create meals which are consistently within ketogenic ratios. Note that the program is very strict, but for people who are ready to do what it takes to get weight loss results, it works.
There is a great deal of science based evidence which shows the following conditions can also be reversed or greatly improved on a keto diet:
The bottom line here is that the ketogenic diet is a powerful metabolic tool for treating a wide range of illnesses. It is not a fad diet, and if it is implemented correctly, it corrects metabolic function at the cellular level. The result is improved health and wellbeing.
A typical ketogenic meal includes a 3-5 ounces of protein, usually cooked in natural fats (for example, butter, lard, duck fat, cream, olive oil, beef tallow, or coconut oil) with the addition of non-starchy or green leafy vegetables such as lettuce, spinach, summer squash, or kale.
