The Ketogenic Diet REVIEW ( information you needed )
Ketosis is an often misunderstood subject. Its presence is equated with starvation or a warning sign of something going wrong in your metabolism. But nothing could be farther from the truth, except if you are an ill-treated type 1 diabetic person.
Ketones – contrary to popular belief and myth – are a much needed and essential healing energy source in our cells that come from the normal metabolism of fat.
The entire body uses ketones in a more safe and effective way than the energy source coming from carbohydrates – sugar AKA glucose. Our bodies will produce ketones if we eat a diet devoid of carbs or a low-carb diet (less than 60 grams of carbs per day). By eating a very low-carb diet or no carbs at all (like a caveman), we become keto-adapted.
What is the Ketogenic Diet?
A ketogenic diet is quite simply any diet that forces the body into a process called ketosis, whereby fats are burned instead of carbohydrates for use as energy. A proper ketogenic diet calls for the dieter to consume high amounts of fat, adequate amounts of protein, and very low amounts of carbohydrates. Our bodies are used to turning carbohydrates into glucose to send all over the body as energy. When we enter ketosis by sufficiently limiting our carbohydrate intake, our livers start breaking down fat cells into fatty acids and ketones, to be used as energy.
Why does the ketogenic diet work?
The ketogenic diet works much like any other diet: by limiting the amount of calories you consume, thereby creating a caloric deficit where the body burns more energy than it takes in. That is the fundamental science of weight loss, and while the “a calorie is a calorie” argument is subject to much debate, few will argue that all successful diets rely on caloric restriction, one way or another.
Our body organs and tissues work much better when they use ketones as a source of fuel, including the brain, heart and the core of our kidneys. If you ever had a chance to see a heart working in real time, you might have noticed the thick fatty tissue that surrounds it. In fact, heart surgeons get to see this every day. A happy beating heart is one that is surrounded by layers of healthy fat. Both the heart and the brain run at least 25% more efficiently on ketones than on blood sugar.
Since the ketogenic diet relies on reducing calories, why cut out carbohydrates at all? Why not just practice calorie counting and focus on eating a traditional low-fat diet like most diet books and nutritionists recommend? What is the advantage of the ketogenic diet?
Great questions. Many of the advantages of the ketogenic diet are rooted in its ability to control hunger much more effectively than other diets:
- Ketogenic Diets control blood sugar and minimize insulin spikes.
When we eat carbohydrates, our blood-glucose levels rise rapidly. This causes an equally rapid insulin response from the pancreatic gland. The insulin disperses excess blood glucose, which causes you to feel hungry all over again. By eating a low carbohydrate diet, we keep our blood sugar levels low and steady, and as a result, carb-induced hunger spikes are avoided. Reducing insulin levels is paramount to success with any diet, as insulin is the hormone that tells our bodies to store fat. By keeping our insulin levels low, we create an environment within our bodies that limits fat storage and promotes fat lipolysis.
- Ketogenic Diets allow us to eat food that is satiating and filling.
Many find that restricting calories on a ketogenic diet is extremely easy. If you’re doing the ketogenic diet properly, you’ll be consuming the vast majority of your calories each day from fats and protein, both of which are extremely filling and can be quite delicious. Once you remove things like refined sugars and simple carbohydrates from your diet, you’ll find that 2,000 calories (or however many you aim to consume) leaves plenty of room to fill yourself up each day. Many keto dieters even find themselves having a hard time consuming enough food each day!
The fact is you get MORE energy per molecule of fat than sugar. How many chronic and autoimmune diseases have an energy deficit component? How about chronic fatigue? Fibromyalgia? Rheumatoid Arthritis? Multiple Sclerosis? Cancer? Back to Allan and Lutz:
Mitochondria are the power plants of the cell. Because they produce most of the energy in the body, the amount of energy available is based on how well the mitochondria are working. Whenever you think of energy, think of all those mitochondria churning out ATP to make the entire body function correctly. The amount of mitochondria in each cell varies, but up to 50 percent of the total cell volume can be mitochondria. When you get tired, don’t just assume you need more carbohydrates; instead, think in terms of how you can maximize your mitochondrial energy production…
If you could shrink to a small enough size to get inside the mitochondria, what would you discover? The first thing you’d learn is that the mitochondria are primarily designed to use fat for energy!
In short, let fat be thy medicine and medicine be thy fat!
