Is There A Difference Between Nutritional Ketosis Vs. Ketosis?

Just to be clear, “nutritional ketosis” is a biological state in which your body is generating ketone bodies to feed your brain in a well-fed state. Your body will also switch to ketone bodies as a primary food source during starvation. But nutritional ketosis is different in a number of ways from starvation. So if you are not starving and you are not taking exogenous ketones and you are getting measurable blood ketone levels, then you are in “nutritional ketosis”. Awesome. Nutritional ketosis is not at all something you would experience from taking exogenous ketones as another answerer suggests. Continue reading >>

    I don't understand at all. Do you do heaps of exercise??? I just don't see how eating nothing but fat is going to make you lose fat. And once you go off the diet (if you ever do), do you just put on a whole lot of weight because you're body isn't used to not having lard every single meal?

    Do you do heaps of exercise?
    No. Exercise has very little to do with weight maintaining your weight long term. When you exercise, you eat more. Don't get me wrong though, exercise is good for you. It's good for your stress level, which for some people can be the reason they're overweight. It's good for your muscles and bones, but weight...meh. I gain weight when I exercise more.
    I just don't see how eating nothing but fat is going to make you lose fat.
    Eating fat doesn't make you fat. It's no different than saying eating brains makes you smart. Excessive calories makes you gain weight. So if you eat the right amount of fat/calories, why would you gain weight? Just cause it's fat?
    What's unique about /r/keto (I do it on occasion) is the hormonal effects it has on your body. When you run on carbs, you spike insulin levels to store the carbs and some carbs are stored as fat. To access that fat for energy, insulin levels have to come down. However, in our highly refined food culture, insulin levels tend to stay elevated after a meal and this is called insulin resistance. We end up cylcing between hyperglycemic, which is lowered by insulin, to hypoglycemia. When we are hypoglycemic (low blood sugar), we get tired and/or hungry. So you eat and you gain weight (if you eat too much). This insulin resistance is a result of 1) excessive refined carbs 2) fructose (sugar) and 3) lack of exercise. The Kitivans eat a ~70% carb diet and are fine. Then they get ~20% of their calories from saturated fat (coconuts). Then they get 5-10% of their calories from fish. They do a lot of manual labor and don't eat that much.
    Keto breaks that cycle. Your blood sugar stays flat and your insulin stays low. It never goes up and it never crashes. Dietary fat is no different to the body than stored body fat. So with insulin levels low, accessing stored body fat becomes easy, so you effectively have an infinite supply of energy. After a while, it becomes trivially easy to eat 1 meal per day. Ketosis also gives you a laser like focus that lasts all the time and is unlike anything you'd experience on a high carb diet. You're not constantly thinking about that next meal.
    And once you go off the diet (if you ever do), do you just put on a whole lot of weight because you're body isn't used to not having lard every single meal?
    It comes down to are you tolerant of carbohydrates or not? If you're diabetic, do keto, lose weight, and stop keto, you're still going to be diabetic and you're going to gain weight. If you were thin before keto (like me) and go off keto, you're still going to be thin. Yes, you will gain 5-10 pounds of water because storing glucose requires you to also retain water, but that's not fat.
    If you have arthritis like me, you might store 15 pounds of extra water on a 115 pound frame. Dropping that water weight totally got rid of my arthritis.

    First of all: Dietary fat and the fat on your body are two different things. Eating fat doesn't make you fat. Eating more calories than you take in makes you fat.
    The reason fat has a bad rap is mostly because of the fact that people hear "1 gram of carbs and protein has 4 calories, but 1 gram of fat has 9" and go, "oh, fat is twice as many calories, better stay away!"
    But that's not telling the whole picture. Fat is much harder for your body to break down, so it makes you feel full for longer. Also, it requires fewer grams of fat to make you feel full. So while yes, 20g of carbs and 20g of fat have different calorie amounts, you might only need to eat 5g of fat to feel as full as you do with the 20g of carbs, resulting in 50 calories of fat vs. 80 calories with carbs.
    The basic idea behind keto is to eat high fat, low carb foods in order to stay full on fewer calories. There's also some science that shows excess carb intake can be detrimental to health. As well as some other science that shows that in the absence of carbs, higher fat intake can do good things for your body. Of course, there's also science that shows the opposite in both cases. Nutritional science is not very well defined, mostly because it's extremely hard to accurately study.
    TL:DR; fat makes you feel the same amount of fullness on fewer calories than carbs, so by avoiding carbs and eating fat, you don't feel the urge to snack, you can more easily cut calories, you lose weight.

What Are The Main Differences Between Nutritional Ketosis, And Ketosis?

I believe these can be used interchangeably. Ketosis is ketosis - this term describes a metabolic state characterized by elevated level of ketone bodies in your blood and low blood glucose levels, induced either by consumption of exogenous ketones or medium-chain triglycerides that are quickly metabolized into ketones, or by starvation (or, at least, restriction of carbohydrates), which switches your body’s metabolic machinery to utilizing fat oxidation as the main source of energy (byproducts of fat oxidation in the absence of glucose are then metabolized further into ketone bodies that can be used as energy substrate by most tissues). “Nutritional ketosis” is more often used to describe a voluntary exercise of inducing ketosis through certain dietary practices (in other words, this is ketosis as a result of a specific nutrition). But, given that nutrition (or lack thereof) still remains a primary method of inducing ketosis (barring direct consumptino of ketone esters, etc.) - most of the time, any ketosis is nutritional ketosis.

How Do Ketosis And Ketoacidosis Differ?

For one a probably 3 to 10 time higher levels of circulating ketones. Here’s what you need to know. Ketones are a natural part of human metabolism. Everybody has circulating levels of ketones in their bodies. When you don’t eat for 12 hours over night your levels of ketones start to rise. The key regulator of ketone production is the hormone insulin. When insulin levels are high, circulating ketones are low. As insulin drops, ketone production starts to rise. Why? Ketones are an alternate fuel for certain tissues in the body. The body starts to ramp up production of ketones in case it needs them to help fuel things like the brain. When concentrations rise about 1 milimolar, the brain starts to burn them as fuel. Ketone metabolism breaks down when insulin is missing in the body. In type 1 diabetics or type 2’s that have beta cell failure, ketone levels can rise to levels of 15 to 25 milimolar. This lack of insulin also causes the massive release of fatty acids which acidify the body and cause the ketones to become toxic by acidifying the ketones. Typically someone on a low carb diet who is in ketosis will have levels of 2 to 3 milimolar. It is very rare for someone with insuli Continue reading >>

    If hyperventilation occurs, excess CO2 gets removed. This shifts the pH of the body slightly to a more alkaline ph (Since CO2 is acidic. Loss of Acid in body = Increase in pH). The change in pH can cause these effects.

  2. Meredith VIguers

    There is a delicate balance of gases in the blood, including oxygen and carbon dioxide, that regulate our system. Usually we think of oxygen as something we need to inhale and carbon dioxide as something to be expelled, but when you hyperventilate, you expel too much carbon dioxide. In the blood, carbon dioxide is important for maintaining the proper pH, as it acts as an acidifier. When too much of it is lost in a short amount of time, you go into a state of what’s called respiratory alkalosis, wherein your blood pH becomes too high or alkaline. This alkalosis causes the symptoms such as dizziness, tingling, fainting, and can even cause seizures and severe spasms if the body is unable to naturally compensate metabolically to reduce to pH of the blood to normal levels and/or the hyperventilation is stopped.
