Ketosis: What Is Ketosis?
Ketosis is a normal metabolic process. When the body does not have enough glucose for energy, it burns stored fats instead; this results in a build-up of acids called ketones within the body. Some people encourage ketosis by following a diet called the ketogenic or low-carb diet. The aim of the diet is to try and burn unwanted fat by forcing the body to rely on fat for energy, rather than carbohydrates. Ketosis is also commonly observed in patients with diabetes, as the process can occur if the body does not have enough insulin or is not using insulin correctly. Problems associated with extreme levels of ketosis are more likely to develop in patients with type 1 diabetes compared with type 2 diabetes patients. Ketosis occurs when the body does not have sufficient access to its primary fuel source, glucose. Ketosis describes a condition where fat stores are broken down to produce energy, which also produces ketones, a type of acid. As ketone levels rise, the acidity of the blood also increases, leading to ketoacidosis, a serious condition that can prove fatal. People with type 1 diabetes are more likely to develop ketoacidosis, for which emergency medical treatment is required to avoid or treat diabetic coma. Some people follow a ketogenic (low-carb) diet to try to lose weight by forcing the body to burn fat stores. What is ketosis? In normal circumstances, the body's cells use glucose as their primary form of energy. Glucose is typically derived from dietary carbohydrates, including: sugar - such as fruits and milk or yogurt starchy foods - such as bread and pasta The body breaks these down into simple sugars. Glucose can either be used to fuel the body or be stored in the liver and muscles as glycogen. If there is not enough glucose available to meet energy demands, th Continue reading >>
10 False Things People Say About Low-carb Diets
When arguing about nutrition, it can be hard to get your point across. People often seem biased against ideas that don't fit with their philosophy. When the topic of low-carb turns up, many people dismiss it, call it a "fad" diet and say that it is either harmful or impossible to stick to. Here are 10 things people say about low-carb diets that just don't make sense. I often see the claim that excluding entire food groups can be hard and that it is impossible to sustain such an "extreme" change in the way you eat. This point kind of makes sense. Not allowing yourself certain types of foods could lead to feelings of deprivation. But the thing is, all diets restrict something. They either restrict food groups or restrict calories. For some people, the calorie restriction approach may be more feasible. But it is NOT the only way. Many people don't seem to understand how low-carb diets work and what their main advantage is when it comes to weight loss. This is the fact that eating low-carb leads to automatic reduction in appetite and effortless calorie restriction (1). Compare that to the low-fat, "balanced" diet - which requires you to count calories and be hungry! This is a graph from one of the studies that compared low-carb and low-fat diets. The low-carb dieters are eating until fullness, while the low-fat dieters are calorie restricted (2). I don't know about you, but I hate being hungry. It is a very uncomfortable feeling. If I get hungry, I eat! If there is a diet plan out there that allows me to eat until fullness and still lose weight, then that sure is hell is the one I will choose. In most studies comparing low-carb and low-fat diets, more people in the low-carb groups make it to the end. If anything, they are easier to stick to. Low-carb diets are not harder to Continue reading >>
New Mother Nearly Dies From A Low Carb Diet: 32-year-old Developed Life-threatening Condition After Ditching Bread, Rice And Pasta While Breastfeeding
A new mother developed a life-threatening condition due to eating a low carbohydrate diet while breastfeeding, doctors claim. The 32-year-old Swedish woman was rushed to hospital with nausea and vomiting, heart palpitations, trembling and spasms in her limbs. When questioned, she said she had been following a a strict low carbohydrate high fat diet (LCHF) in order to lose her baby weight, doctors describing her case in the Journal of Medical Case Reports said. The regime saw the woman, who is unidentified, eating less than 20g of carbohydrate day, the equivalent of a medium-sized potato, or a thick slice of toast, while breastfeeding her 10-month-old son. In the UK, adults are advised to get half of their daily energy intake from carbohydrates, according to a report by the Scientific Advisory Committee on Nutrition, who advise the Government. This is the equivalent of 200 - 240g of carbohydrates in a person eating 2,000 calories a day. The woman said she had lost 4kg on the diet but had begun to feel very ill. In hospital, medics carried out tests and discovered she was suffering from ketoacidosis, a rare but potentially life-threatening condition normally seen in people with type 1 diabetes. ‘The primary diagnosis was thought to be ketoacidosis due to starvation induced by the LCHF diet,’ doctors writing in the journal. When a person has raised blood glucose levels, or are eating a low carbohydrate diet, their body may go into a state of ketosis. Ketosis is a state the body goes into if it needs to break down body fat for energy. The state is marked by raised levels of ketones in the blood which can be used by the body as fuel. Ketones which are not used for fuel are excreted out of the body via the kidneys and the urine. In ketosis, the level of ketones in the blo Continue reading >>
Is Ketosis Dangerous?
Duck Dodgers October 14, 2014 Peter, An article by Per Wikholm was published in this month’s LCHF Magasinet, where Per demonstrates that the Inuit could not have been in ketosis given that the scientific literature is abundantly clear, over and over again, that the Inuit consumed too much protein, and more importantly, Per debunks Stefansson’s claims for high fat with writing from his own books—Stef admitted in the pemmican recipes that Arctic caribou was too lean to make pemmican that supported ketosis. The most popular LCHF bloggers in Sweden, Andreas Eenfeldt/Diet Doctor and Annika Dahlquist have reluctantly agreed with Per’s findings—admitting that the Inuit were likely not ketogenic from their diet. I’ve put together a comprehensive review of the scientific literature regarding the Inuit, encompassing over two dozen studies, spanning 150 years, with references from explorers, including Stefansson. In the comments section of that post, Per gives a brief overview of how he was able to prove Stefansson’s observations on high fat intake were flawed. The post is a review of all the available literature that I could find (over two dozen studies). But, the literature certainly does not in any way support ketosis from the Inuit diet due to such high protein consumption. As Per (and Stefansson) points out, the caribou is too lean and as the many quotes show, the Inuit were saving their blubber and fat for the long dark Winter to power their oil lamps and heat their igloos. Again and again, we see that in the literature, as even Stefansson admits this. As far as glycogen is concerned, their glycogen intake is probably not worth scrutinizing given the well-documented high protein consumption in every published study. It really is besides the point. But, interest Continue reading >>
Diabetes & Ketogenic Diet: Can You Manage Your Diabetes On A Ketogenic Diet?
In this article we will cover what a Ketogenic diet is and if you can manage your diabetes while on this diet. Ketogenic diet for diabetics is a highly controversial topic, but we will break down everything here for you! As a Certified Diabetes Educator (CDE), I have to tell you from the start I will have a biased view here. Sorry, but I feel that I need to be completely honest right up front! I will however, present all the evidence that is available currently on the subject. As a CDE, I have been taught to follow the American Diabetes Association Dietary Guidelines for Americans which is low in carbohydrates, high in fiber, with fresh vegetables, fruits and whole grains. The Ketogenic Diet this article will be discussing is much lower in carbohydrates, in order to promote the state of nutritional ketosis, or the fat burning state for weight loss. What is a Ketogenic Diet? The Ketogenic Diet is a low carbohydrate diet, consisting initially of less than 20 carbohydrates per day. Not per meal, yes, you heard me correctly, per day. It is not for the faint of heart and yes I am writing from experience. Of course I have tried it! Hasn’t everybody in America at some point who has wanted to lose weight? Does it work you ask? Of course it does! The problem is how long can you keep it up? Your body uses the carbohydrates you eat for energy, so if we restrict how many carbohydrates we eat, the body has to get its fuel source from fat. A byproduct of this fat burning state are ketones which are produced; this is called nutritional ketosis. You can determine if you are in this fat burning state by purchasing urine ketone testing strips from your local pharmacy. The Ketogenic Diet with Diabetes Some precautions must be made clear; this diet is not appropriate for people with any Continue reading >>
Is Ketosis Dangerous? No, Because Ketosis Is Not Ketoacidosis.
At this point, I consider myself pretty immune to what internet trolls say to me. I have a pretty tough skin, usually laugh off nonsensical comments, and carry on with my day. This last time was different. When checking the social media account for my ketosis supplement company, Perfect Keto, I noticed a rather ridiculous comment. To the best of my memory, the comment said something like this: “How dare you promote ketosis?! I HATE KETOSIS! My daughter is a diabetic and had to be brought to hospital the other day because she was in ketoacidosis! Shame on you and everyone like who you recommends a dangerous diet that kills people! You are killing people! AGHHH!” Not only is this comment wildly misinformed and ignorant, I think comments like this are more dangerous than the promoting the ketogenic diet. When people make comments like this, they use the same scare tactics and lack of facts that have recently overtaken our political system to influence people in not using very beneficial tools to their advantage. Sometimes you just have to use your brain. The unfortunate truth is that this lady isn’t the only delusional and misinformed one instilling fear into people who are trying to gain benefit from their nutritional choices. Plenty of mainstream doctors also think the ketogenic diet is life threatening. I’ve recommended the ketogenic diet to many of my patients trying to fix weight and metabolic issues they haven’t been able to correct for years. One of them mentioned this change to their primary care physician, who was reviewing the statins and several other medications they have this patient on, who reacted with disbelief. Ketosis! How could I recommend such a life threatening intervention?! They were told not to see such a quack like myself any more before Continue reading >>
How Long Can You Eat Ketogenic? Isn't It Dangerous In The Long-term?
1) Is Keto diet dangerous for the liver, the kidneys, the heart? Especially the way the body has to work to turn fats into glyco for the body. Is it harmful in anyway? There’s no evidence to suggest that it is harmful to any of the organs you mention. There is no evidence to suggest that it is harmful to you in any way, really. There is a lot more evidence that a Low Fat diet it much more harmful in almost every way. It’s actually VERY normal for the human body to spend generating most of its glycogen from fat (ie, being in the “Fat burning zone” of cardio). Insulin tells your cells to take up glucose and store it - for fat cells that means turning it into fat - which is then later turned back into glycogen once the blood glucose levels drop. 2) Is it a diet I can stay on, on a lifelong basis? Because I don’t want to gain all my weight back in the end, I want to continue my sports sessions and I want to be in good health. Is keto diet compatible with that? And yes, it’s very compatible with that. You can find evidence of powerlifters, cyclists, and everything in between thriving on a ketogenic diet. Until you get adapted it can be pretty tough (maybe a month or two), but once you are, you will not notice adverse effects. I will tell you though, it it challenging to do mostly because it seems EVERYTHING in the WHOLE WIDE WORLD except what you cook at home or Chipotle is just full of carbs - so I always feel like I’m fighting a battle against the world to maintain the diet when I am in any situation that is outside my “normal” routine.
