What Is Ketosis, And Is It Healthy?
Ketosis is a natural metabolic state. It involves the body producing ketone bodies out of fat, and using them for energy instead of carbs. You can get into ketosis by following a very low-carb, high-fat ketogenic diet (1). In addition to fast weight loss, ketosis may have several health benefits, such as reduced seizures in epileptic children (2). Ketosis is quite complex, but this article explains what it is and how it can benefit you. Ketosis is a metabolic state in which fat provides most of the fuel for the body. It occurs when there is limited access to glucose (blood sugar), which is the preferred fuel source for many cells in the body. Ketosis is most often associated with ketogenic and very low-carb diets. It also happens during pregnancy, infancy, fasting and starvation (3, 4, 5, 6). To go into ketosis, people generally need to eat fewer than 50 grams of carbs per day and sometimes as little as 20 grams per day. This requires removing certain food items from your diet, such as grains, candy and sugary soft drinks. You also have to cut back on legumes, potatoes and fruit. When eating a very low-carb diet, levels of the hormone insulin go down and fatty acids are released from body fat stores in large amounts. Many of these fatty acids are transferred to the liver, where they are oxidized and turned into ketones (or ketone bodies). These molecules can provide energy for the body. Unlike fatty acids, ketones can cross the blood-brain barrier and provide energy for the brain in the absence of glucose. Ketosis is a metabolic state where ketones become the main sources of energy for the body and brain. This happens when carb intake and insulin levels are very low. It's a common misunderstanding that the brain doesn't function without dietary carbs. It's true that glu Continue reading >>
Ketogenic Diet: Is The Ultimate Low-carb Diet Good For You?
Recently, many of my patients have been asking about a ketogenic diet. Is it safe? Would you recommend it? Despite the recent hype, a ketogenic diet is not something new. In medicine, we have been using it for almost 100 years to treat drug-resistant epilepsy, especially in children. In the 1970s, Dr. Atkins popularized his very-low-carbohydrate diet for weight loss that began with a very strict two-week ketogenic phase. Over the years, other fad diets incorporated a similar approach for weight loss. What is a ketogenic diet? In essence, it is a diet that causes the body to release ketones into the bloodstream. Most cells prefer to use blood sugar, which comes from carbohydrates, as the body’s main source of energy. In the absence of circulating blood sugar from food, we start breaking down stored fat into molecules called ketone bodies (the process is called ketosis). Once you reach ketosis, most cells will use ketone bodies to generate energy until we start eating carbohydrates again. The shift, from using circulating glucose to breaking down stored fat as a source of energy, usually happens over two to four days of eating fewer than 20 to 50 grams of carbohydrates per day. Keep in mind that this is a highly individualized process, and some people need a more restricted diet to start producing enough ketones. Because it lacks carbohydrates, a ketogenic diet is rich in proteins and fats. It typically includes plenty of meats, eggs, processed meats, sausages, cheeses, fish, nuts, butter, oils, seeds, and fibrous vegetables. Because it is so restrictive, it is really hard to follow over the long run. Carbohydrates normally account for at least 50% of the typical American diet. One of the main criticisms of this diet is that many people tend to eat too much protein and Continue reading >>
Is Jogging Good During Ketosis?
There’s been a recent large movement towards implementing keto diets for endurance runners. Because your body uses fats for fuels, when jogging you’re less likely to experience the spikes and pitfalls when using glycogen (sugars) for fuel. Maintained, sustainable energy is one of the biggest advantages of keto diets in the first place, so jogging and other endurance cardio is fantastic while in ketosis. Now whether an hour of jogging is enough to lose weight is another story. The amount of time you jog is really only one factor of total weight loss. What’s more important is how many calories you’re burning while you jog, and how many calories you’re currently eating on your keto diet. If you want to lose weight on any diet, your body needs to be going through less calories, which means you either need to eat less calories, or maintain your caloric intake while adding calorie burning exercises. If you ever need help finding good foods for keto and weight loss, here’s a guide for what foods are good to eat, what foods should be eaten in moderation, and what foods you should avoid on keto: Diet Comparison Food Resource Guide - Blue Tree Health Continue reading >>
What Is Good For Heavy Metal Detoxification? And Does Going Into Ketosis Help?
Let me start with mercury because in some ways it is the most difficult heavy metal to excrete efficiently. Mercury bonds efficiently to sulfur, much better than it bonds to oxygen. Lead bonds to oxygen better, and this defines a critical difference in detox between different heavy metals. The body can have a high mercury burden and be asymptomatic. Teenagers with idiopathic dilated cardiomyopathy suddenly drop dead; that's how we find out they have toxic mercury burdens in their heart muscles. In humans, mercury is detoxified by binding to glutathione (GSH), which binds to mercury (Hg) by its sulfur (S) atoms. Glutathione is abbreviated GSH to emphasize the sulfhydryl (SH) active group, which when it bonds to mercury becomes GS-Hg-SG (two bonds to the sulfur (S) of glutathione). The H of GSH is replaced with mercury. This bound form of mercury is our body's primary mercury-defense mechanism, for storage in the cells and for elimination through the liver into the bile. The latter is where the problem begins. When mercury enters the digestive tract in bile, it runs into microorganisms. Bacteria hate mercury in the glutathione-bound form. It gets into their systems very efficiently, wreaks havoc, and they use an entirely different detox mechanism: methylation. They convert the GS-Hg-SG into methylmercury, which is eliminated by the bacteria into the gut and diffuses back into our bodies. Ouch. Because methyl mercury readily crosses the blood-brain barrier, very ouch. This is why you shouldn't get mercury chelated by your local alternative doctor with an IV. When too aggressive, IVs "stir up" too much of the mercury and it relocates in ways that aggravate many toxicity symptoms. This does not apply to lead, which IV chelates quite well. I wish I had better news to relate r Continue reading >>
What Is Ketosis?
"Ketosis" is a word you'll probably see when you're looking for information on diabetes or weight loss. Is it a good thing or a bad thing? That depends. Ketosis is a normal metabolic process, something your body does to keep working. When it doesn't have enough carbohydrates from food for your cells to burn for energy, it burns fat instead. As part of this process, it makes ketones. If you're healthy and eating a balanced diet, your body controls how much fat it burns, and you don't normally make or use ketones. But when you cut way back on your calories or carbs, your body will switch to ketosis for energy. It can also happen after exercising for a long time and during pregnancy. For people with uncontrolled diabetes, ketosis is a sign of not using enough insulin. Ketosis can become dangerous when ketones build up. High levels lead to dehydration and change the chemical balance of your blood. Ketosis is a popular weight loss strategy. Low-carb eating plans include the first part of the Atkins diet and the Paleo diet, which stress proteins for fueling your body. In addition to helping you burn fat, ketosis can make you feel less hungry. It also helps you maintain muscle. For healthy people who don't have diabetes and aren't pregnant, ketosis usually kicks in after 3 or 4 days of eating less than 50 grams of carbohydrates per day. That's about 3 slices of bread, a cup of low-fat fruit yogurt, or two small bananas. You can start ketosis by fasting, too. Doctors may put children who have epilepsy on a ketogenic diet, a special high-fat, very low-carb and protein plan, because it might help prevent seizures. Adults with epilepsy sometimes eat modified Atkins diets. Some research suggests that ketogenic diets might help lower your risk of heart disease. Other studies show sp Continue reading >>
Is It Good To Do Heavy Lifting While In Ketosis Or On A Ketonic Diet?
I would not expect PR’s (Personal Records) when in ketosis. You are going to have a hard time lifting heavy in ketosis. I’m sure you have already experienced that. If you are trying to build muscle while in ketosis you don’t have to lift heavy. In fact, In order to achieve your best body, you must optimize all three of these advanced methods for rapid muscle growth. A 2010 paper in the Journal of Strength & Conditioning Research by Brad Schoenfeld identified these three mechanisms of rapid muscle growth as – mechanical tension, metabolic stress, and muscle damage Most guys who do not know how to optimize all three of these factors (mechanical tension, metabolic stress, and muscle damage) to muscle growth, end up spinning their wheels and become frustrated as to why they look the same month after month, year after year. The fact is, muscle needs stimulation to grow. If you don’t expose your muscle to stress, there’s no driving force for muscle to grow. The three proven methods below reveal EXACTLY how you can increase your muscle size and strength and incinerate fat… for your best body EVER—while you avoid plateaus caused by crappy and boring workouts that have already failed you in the past… Continue reading >>
How Can I Keep Muscle While In Ketosis?
Ketogenic diets are great for shocking the body and work very well when body fat levels are somewhat higher (over 12%). Below that, and considering you need to keep protein intake at high levels, muscle retention will suffer as your metabolism will start dropping and your body will prefer to use and break down your much-more-energy-demanding muscle fiber, instead of your necessary-for-survival fat pockets (according to your dna's blueprint). Switch to a high protein diet (0.9 - 1gr of protein per pound of weight daily) with some decent carbs (cycling them between lifting and rest days) to maintain decent testosterone levels, which you need for muscle retention and to avoid the flat look. As long as you are on a deficit (20-25% below maintenance) and your protein is high, while lifting as heavy as before at least twice a week (you might want to leave some additional rest time too), you're golden. Throw in some carb up days on heavy lifting days, as well as occasional diet breaks (every 2 months at least) for a linear drop down to single digits. Continue reading >>
What Are The Main Differences Between A High Protein/low Carb Diet And A High Fat/low Carb Diet Both Leading To Ketosis?
A high protein/low carb diet would be something similar to the Atkins diet. The benefits as related to a typical western diet are weight loss and less fluctuations in glucose levels. As other contributors have mentioned, one limitation of too much protein intake is the process of gluconeogenesis where excess protein is converted into glucose in the liver and eventually stored as fat. A ketogenic (high fat/low carb) diet tries to minimize this process by reducing the amount of protein consumed and at the same time maximizing the healthy fats consumed to increase ketones production and satiety. The other benefit of a ketogenic lifestyle (if done right) is a focus on the quality of fat consumed versus just any type of fat. This leads to improved mitochondrial function and less overall inflammation, leading to weight loss and better hormonal regulation. Hi. Having low carb naturally ups the other macros. The difference though is high protein—this is relative of course. With carbs, we limit it to a specific number. Protein differs depending on size, muscle mass, and activity. But having too much can arguably stress your kidneys. It is also insulinogenic—less than carbs but it still spikes insulin. This therefore, can slow down ketosis entry and even kick you off ketosis. High fat provides better insulin control. It also doesnt tax your kidneys. As a rule, I recommend .6–1 gram or protein per pound. Just adjust depending on activity, if you train etc Continue reading >>
Is Doing Hitt A Good Way To Go Into Ketosis Fast?
You asked, Is doing HITT a good way to go into ketosis fast? Ketosis occurs at the point in time when the body exhausts sufficient blood glucose to sustain metabolic energy and biosynthesis needs. Gluconeogenesis is the short-term energy bridge when episodic metabolic needs arise (whereby the liver transforms bodily proteins into glucose); however: It takes the average male 72 hours to engage ketosis and average female 48 hours. It is less the excessive immediate energy demands that speed ketogenesis than the constant demand for energy above current blood glucose supply. As such, intense short-term demands are inconsequential to the speed of ketogenesis–it’s the duration of those demands that matter. The most correlative factor regarding increasing the speed of ketosis is developing underlying ketoadapted fitness in the individual. Much of ketoadapted fitness is easily cultivated through diet (i.e. ketogenic) and short-term water fasting (i.e. more than three and up to 40 days*). So judging HIIT as either a good or bad way to engage ketosis really depends upon the underlying ketoadapted fitness of the individual (or lack thereof) and whether or not you want to accomplish additional outcomes by invoking that practice. *Long-term fasting (on water alone) has been repeatedly defined as fasts exceeding 40 days, in both extant literature and clinical records of fasting as a therapeutic protocol. Unfortunately the wisdom and execution of such practices are virtually extinct in modern allopathic practice, for a variety of reasons. As such it is rarely recommended to fast for more than 10 days without a fasting expert with direct experience, as conventional medical doctors simply have no clue. And keto-adapted fitness can be easily cultivated within short-term fasting proto Continue reading >>
The Keto Diet Is Gaining Popularity, But Is It Safe?
A new twist on extreme weight loss is catching on in some parts of the United States. It’s called the "keto diet." People promoting the diet say it uses the body’s own fat burning system to help people lose significant weight in as little as 10 days. It has also been known to help moderate the symptoms of children with epilepsy, although experts are not quite sure why it works. Proponents say the diet can produce quick weight loss and provide a person with more energy. However, critics say the diet is an unhealthy way to lose weight and in some instances it can be downright dangerous. Read More: What is the “Caveman Diet?” » What Is Ketosis? The “keto” diet is any extremely low- or no-carbohydrate diet that forces the body into a state of ketosis. Ketosis occurs when people eat a low- or no-carb diet and molecules called ketones build up in their bloodstream. Low carbohydrate levels cause blood sugar levels to drop and the body begins breaking down fat to use as energy. Ketosis is actually a mild form of ketoacidosis. Ketoacidosis mostly affects people with type 1 diabetes. In fact, it is the leading cause of death of people with diabetes who are under 24 years of age. However, many experts say ketosis itself is not necessarily harmful. Some studies, in fact, suggest that a ketogenic diet is safe for significantly overweight or obese people. However, other clinical reviews point out that patients on low-carbohydrate diets regain some of their lost weight within a year. Where It’s Helpful The keto diet was created by Dr. Gianfranco Cappello, an associate professor of surgery at the Sapienza University in Rome, Italy. He claims great success among thousands of users. In his study, more than 19,000 dieters experienced significant, rapid weight loss, few side Continue reading >>
How Long Can You Stay In Ketosis Safely?
Are you looking for a diet for weight-loss or fat-loss? If so then you might be interested in ketosis. The question is whether you can stay on it permanently. That’s because it’s critical for any ‘diet” to become part of your everyday life and eating habits. It’s important to first understand what it is all about. It’s a natural state of the human body when it’s fueled almost 100% by body fat. This state takes place during a low-carb or “keto” diet as well as during fasting. It’s important to understand how this process is related to fat loss. The term originates from the fact that the human produce produces tin fuel molecules known as “ketones.” When the body doesn’t have enough blood sugar/glucose it gets energy from this source. The body produces chemicals when it gets a very low supply of carbs and a moderate amount of protein. The liver’s fat produces ketones then the body and brain use it for fuel. The process is especially important for the brain since the organ can only run from glucose/ketones. Medical research shows that early humans probably experienced the state very often. The reason is that hunter-gatherer societies ate a high-meat diet and had less access to carbohydrates than modern humans. As a result human bodies evolved so they could get energy from fat even though it mimicked starvation mode. Today there are various reasons why people use the ketogenic meal plan. Some of the most common ones are to lose weight or control epilepsy. The firm supporters point out the health benefits of the diet but others note that it’s a dangerous “hack” of the body’s regular metabolic system. These are the benefits to this process: Less eating due to no appetite More fat loss from abdominal cavity Lower blood sugar/insulin levels Lo Continue reading >>
Is Going In And Out Of Ketosis Bad?
In the earlier stages of adaptation going into ketosis may feel bad and going out may stop your progress for a fair while, so is to be avoided if all possible IMHO. Eventually once properly adapted you should have a lot more metabolic flexibility and will more readily switch. At that point you should mostly not notice anything anymore. Apart from how it feels, it is IMHO obviously not bad for you to switch energy pathways as conditions demand, that’s just part of how your metabolism works to help ensure you’re properly fuelled. According to Dr. Colin Champ, oncologist and assistant professor at the University of Pittsburgh Cancer Institute and University of Pittsburgh Medical Center, for weight loss in someone who doesn’t have much to lose, periodic ketosis for a couple days seems to work. For others with a lot of weight to lose and/or those that do poorly with carbohydrates, the diet may need to be maintained for several months. He said: “I personally go in and out of ketosis frequently, getting very strict every month or two for about 5 days. I have been in ketosis for 6 months and even over a year, but function and feel better when I avoid long-term ketosis.” Anecdotally, when some individuals still have some fat to burn, they thrive in ketosis for longer periods of time more so than others. Some longer-term ketogenic diet followers do experience hormonal changes and probably should not be on the diet for an extended period of time. Continue reading >>
