Fat Loss Calculator: http://bit.ly/2O6rsdo The carb cycling diet is one of my favorite diets because it is one of the fastest way to burn fat while retaining as much muscle as possible. Most people don't know that carb cycling is actually a form of ketogenic dieting. The ketogenic diet is a diet that is lower in carbohydrates, which makes our body convert more dietary fat and body fat in to keytones in the liver. Which it then goes on to use for energy. Like I've said in many of my videos the human body prefers to use carbs as its primary source of energy. You're body won't produce too many keytones on a high carbohydrate diet, because your body won't need extra energy from fat due to the fact that its getting its energy from the more preferred carbohydrates. The only way for our body to use more fat for energy is by not having its preferred source there all the time. Eliminating carbs completely, however can have many drawbacks on our health and well being. Protein, carbs, and fats are all important and necessary for our body. So in comes the cyclical ketogenic diet aka carb cycling and also known originally as the a

What Does Craig Good Think About The Ketogenic Diet?

It’s a fad - (It’s not - in actually got it’s first popularity in 1863.) It’s something you should only do under the care of a doctor People that write about it are nuts. I’m adding a personal anecdote to #2. See, I followed the recommendation of the American Diabetes Association (until 2008 they mentioned zero, nada about low carb diets.) My diabetes doctor sent me to a dietician who told me to eat a “low fat diet, and healthy whole grains.) I followed my doctor’s advice. The problem was that advice caused me to need to inject at least 60 units of insulin a day and still see fasting blood sugars in the 190 range. Only after starting a ketogenic diet could I start to see normal blood sugars while leaving insulin behind. Mr. BNBR says I shouldn’t say more than equate Mr. Good’s advice to the stuff we had to avoid when I marched in parades in college. Edited following response from the Quora messiah Craig Good Let me deal with Mr. Good’s insubstantial (but already upvoted answer.) It’s a starvation response NO NO NO. Think of how illogical this is. People are well fed, they have sufficient nutrition and all of the essential nutrients in their diets. Their bodies Continue reading >>

    Insulin is an essential hormone, necessary for metabolism of glucose and thus energy production. It’s the lack of insulin, or the inability to respond to it, that creates problems. While Type I diabetics don’t make enough, Type II diabetics initially produce above-normal amounts of insulin because their tissues are relatively insensitive to the hormone (over time, their insulin production may drop as well, but the amount of supplemental insulin required to normalize blood glucose often remains elevated).

  2. Craig Good

    Never ask why until you’ve asked if. Insulin is not the root cause of any health problem. Inappropriate insulin levels can be primary symptoms of a number of health problems. As for what it does, see the Role of Insulin in the Body and Effect on Blood Glucose .

    How so it is the root cause of many health problems? It is not. We need insulin to lower elevated, thus regulate, our blood glucose levels.

Does Fasting Help Creativity? I Heard After Three Days Of Fasting Your Body Produces Ketones Which Can Help With Creativity. Is This True And Safe?

Does fasting help creativity? I heard after three days of fasting your body produces ketones which can help with creativity. Is this true and safe? Creativity is an undefined and broad concept, so it's impossible to say that anything helps creativity unless you better define creativity so as to be an observably definable and measurably improvable state. Yes, it's true, after three days [of fasting] the [average] body will produce ketones. The inherited wisdom is that it takes the average woman 48 hours and the average man 72 hours to mobilize ketones and up-cycle into ketosis. And these are more generalized rules of thumb than actual immutable facts of direct experience, e.g. individuals that deep fast seasonally can mobilize full ketosis in less than 24 hours. Yes, it's more than safe – fasting is one of the longest retained evolutionary processes universally distributed to most all humans* for self-regulation of health, hygiene and improved well-being required for human survival. Fasting also still serves many cultural, religious and spiritual intents across the world. Fasting is only contraindicated in exceedingly few circumstances across those of the general population: peopl Continue reading >>

    Others have mentioned the chemical details that lead to limits. That's only one side of the story. The other side is redundancy in energy production. Ketones can be used in anaerobic energy production. It's not as efficient but it is faster. There are times when fast beats efficient so redundancy gets selected for.

    Acetyl CoA can’t be circulated for two reasons: it’s a high energy compound and it’s labile. So it’s not a stable form for circulation to tissues. Also acetyl coA cannot cross cell membrane.
    Ketone bodies are an alternate fuel source. More importantly, they are water soluble analogs of fatty acids. This is important since, during starvation there is fat breakdown and excess fatty acids circulate in blood. However, fatty acids cannot be used by brain as fuel since, they cannot cross the blood brain barrier. Liver by producing ketone bodies helps brain cells during starvation.

    Also, these ketone bodies, as such, can be used by other tissues as well. There by other tissues refrain from using glucose. Hence, ketone bodies have a glucose-sparing effect. This glucose will be available for tissues like brain and red cells for use.

    It’s because oxaloacetate is needed to metabolize acetyl-CoA (first step in the Krebs cycle is the reaction of acetyl-CoA with oxaloacetate) and is also needed (and used up) in gluconeogenesis (the production of glucose from amino acids and other small molecules, but NOT from acetyl groups or fatty acids). The liver is primarily responsible for gluconeogenesis, and if it uses up oxaloacetate on that, acetyl-CoA builds up and ties up all the coenzyme A in acetylated form. In order to alleviate this, the liver converts the acetyl-CoA into ketone bodies, and releases them into the blood. These, as the book says, are taken up by other tissues (such as brain and muscle) and converted back into acetyl-CoA. A key point is that these cells can use the acetyl-CoA because they are not depleted in oxaloacetate because they do not carry out gluconeogenesis.

Why Does Diabetes Cause Ketosis?

In diabetes due to the insulin deficiency there is increased hepatic gluconeogenesis and lipolysis And this lipolysis inturn increases free fatty acids. Now you know that as insulin is deficient in diabetes glucose cant be utilised as a energy source. So to get the energy an alternative source of these free fatty acids are used. End ketones being the end product of this fatty acid metabolism it gets accumulated. Initially it causes ketonemia(increased ketone bodies in blood) but this cycle keeps on going at ketoacidosis occurs. P.S- I just tried to simplify the answer,the exact mechanism is complex as there are lot of steps involved in it. Continue reading >>
