Ketones: Clearing Up The Confusion
Ketones, ketosis, ketoacidosis, DKA…these are words that you’ve probably heard at one point or another, and you might be wondering what they mean and if you need to worry about them at all, especially if you have diabetes. This week, we’ll explore the mysterious world of ketones, including if and how they may affect you. Ketones — what are they? Ketones are a type of acid that the body can form if there’s not enough carbohydrate to be burned for energy (yes, you do need carbs for fuel). Without enough carb, the body turns to another energy source: fat. Ketones are made in the liver from fat breakdown. This is called ketogenesis. People who don’t have diabetes can form ketones. This might occur if a person does extreme exercise, has an eating disorder, is fasting (not eating), or is following a low-carbohydrate diet. This is called ketosis and it’s a normal response to starvation. In a person who has diabetes, ketones form for the same reason (not enough carb for energy), but this often occurs because there isn’t enough insulin available to help move carb (in the form of glucose) from the bloodstream to the cells to be used for energy. Again, the body scrambles to find an alternate fuel source in the form of fat. You might be thinking that it’s a good thing to burn fat for fuel. However, for someone who has diabetes, ketosis can quickly become dangerous if it occurs due to a continued lack of insulin (the presence of ketones along with “normal” blood sugar levels is not necessarily a cause for concern). In the absence of insulin (which can occur if someone doesn’t take their insulin or perhaps uses an insulin pump and the pump has a malfunction, for example), fat cells continue to release fat into the circulation; the liver then continues to churn Continue reading >>
Can "bad" Stomach Bacteria Feed On Ketones?
Only bacteria that can survive high acidity in the stomach is Helicobacter pylori and it’s a direct cause of stomach ulcers, gastro-esophageal reflux disease, etc. You probably meant intestinal bacteria. Bad intestinal bacteria are there usually because of the antibiotic misuse. Treatment is with pro-biotics. Some bacteria almost certainly can use glucose, ketone bodies, and everything else for food. Do they actually thrive on them, I don’t know. Ketogenic diet do not have any untoward effects on the intestine. Continue reading >>
What Are Some Concerns With Genetically Modified Organisms And Food? If Gmo Food Has The Potential To Dramatically Increase Our Food Production, Why Is It So Bad?
To answer this question, I've synthesized a number of my other answers on Quora. The main concerns about GMOs are: health/safety, the environment, corporate control. Health/safety is the easiest one: it should be a simple scientific question, and regulators in countries that are approving of GMOs treat it that way. The theoretical potential for harm exists, but based on regulated practices, they're safe. The environment and corporate control issues are more complex, because these are at the population-level. These concerns have legitimacy, though they are always overblown. They are harder to measure, involve many interacting factors, and in all cases, there is no such thing as a completely objective, scientific answer. Your personal viewpoints matter. Alright, let's get into some details. Why are people concerned about GMOs? First of all, the concern exists, because food affects us all. It's hard to fully emphasize just how personal food and the food supply is to individuals and communities. So both opponents and proponents have very personal reasons for rejecting or accepting GMOs, even if the real effects (risks or benefits) are actually much more benign. That evokes a lot of controversy, because everybody feels they have a personal stake. Why are so many people opposed to genetically modified food when scientific research shows it is safe? Why are GMOs controversial? The emotion that food evokes makes it an easy target for stoking concern. Organizations of all stripes have abused this: "GMOs may be harmful to your health!" or "GMOs are needed to feed the world!" No other issues introduce concerns of health, safety, the environment, and the politics of government and corporations to such an extent. That applies to broadly to food politics, but the particular focus on Continue reading >>
Will It Be Harmful For Our Brain If We Stop Eating Sugar (i.e. Sugar Free Diet)?
No. There is absolutely no biological need for sugar in your diet. In fact, the only carbohydrate that is an absolute “need” for your body is fiber. Your body can create any needed from fats and proteins. This is called gluconeogenesis. Your body will make any needed carbohydrates. The Institute of Medicine has stated: "The lower limit of dietary carbohydrate compatible with life apparently is zero, provided that adequate amounts of protein and fat are consumed." Continue reading >>
What Are The Major Myths About Ketogenic Diet?
For me the decision to transition into ketogenic diet was a tough one. I had a gut feeling that I needed keto therapy. However, many doctors told me that it was a bad idea. They say the same now, even though they see the results. · Anxiety and depression gone · 10 kg of fat gone · Cognitive function increased · Physical and mental energy levels increased It is shocking! The results are here, and medical experts still repeat their mantras. Like most of people I respect professionals and their opinions. That is why I asked medical experts for an advice on how to get into ketosis in a safe and painless manner. Unfortunately, many doctors have extremely outdated views on nutrition. They live in old myths and stereotypes. Here is my favorite myth about ketogenic diet. Ketosis is dangerous. This I heard from several doctors who confused nutritional ketosis with diabetic ketoacidosis. Nutritional ketosis is a natural state that our body uses to survive during inadequate food supply. This is an evolutionary adaptation mechanism. It is very simple. When we do not have supply of carbohydrates our body starts producing ketones. Blood sugar (glucose) goes down, insulin goes down, and then stored fat is released with ketones level going up. Here is how deep ketosis looks like. This is happening for one reason. Our brain needs energy. There are only two types of energy sources for the brain. They are glucose and ketones. Ketones can be used only when glucose if very low. When we lived in caves we did not have abundance of food so we learned to store energy as body fat. Carbohydrates is an investment type of food. If you do not burn them immediately it becomes fat. Your liver makes fat out of bread, pasta, cola, rice, etc. for future consumption. Fat is a consumption type of food. Continue reading >>
