What Happens To Your Body During Ketosis?
What happens to your body during ketosis? That’s exactly what we’re looking at right now and tracking. So to be more specific then, what’s happening to my body during ketosis. Just to catch everyone up on things, here’s where I’m at. I have been on some form of slow-carb diet for years. Not very disciplined mind you and the carbs I did eat were nutritious. I stay really far away from overly processed foods and sugar, I time carbs around exercise so they get used for intended purposes and I do not consume alcohol. Before ketosis, dinner looked something like big salad to start, fish or chicken, black beans, a little brown rice, avocado. Rest of the time, low to no carbs, high protein, good fats. Tracked nothing. Minimal food during the day, big dinner at night. Treats were whatever the hell I wanted because I know that 85% of the time, I’m good. Really good. 15% of the time was dedicated to whatever. Especially when you’re doing the intermittent fasting and timing cheats around post exercise intensity. When you decide to eliminate all sugar and starch from the diet and your only source of carbohydrates comes from vegetables and some dairy, things change. The goal? Get the body to use fat for fuel. Inspired by listening to a Joe Rogan podcast with Mark Sission, I thought, let’s give this ketogenic diet another shot. I did it once a few years back but quickly moved over to The Warrior Diet which is where I spend most my eating habits anyway. Late February, I drop the starch, sugar, fruit in favor of more and better fats, lower the protein a bit and away we go. Within a few days, them ketostix are looking good and I’m off and running. However, the sticks soon return to normal. Am I in ketosis? Am I using fat for fuel? Well, the good news is, without testin Continue reading >>
The Beginners Guide To Ketosis: Investigating Low-carb, High-fat Eating
The only hard and fast rule of health is that health is personal and what works well for one person may not work for someone else. Aside from that rule, there are “frameworks” that seem to benefit large groups of people. One more level down from that are alternative strategies that benefit smaller groups. Ketosis is likely one of those alternative strategies that works well for certain, smaller groups of people. So, right off the bat I want you to understand that Ketosis might not be for everyone. I’m going to lay out the case for potential benefits of Ketosis. If it sounds interesting and beneficial to you, then consider trying it. (see our free cheat sheet to help you). What is Ketosis Ketosis occurs when liver glycogen gets depleted and the body burns fatty acids for fuel. The primary driver of this state is a very low carbohydrate intake. Often, it also requires a low protein, higher fat intake. You can also achieve a state of ketosis by not eating altogether. The creation of ketones is a byproduct of this metabolic state. Ketones are a source of fuel, just as glucose is a source of fuel. Ketones tend to have some added benefits, though. What role does Ketosis play in human health? Ketosis allows our bodies to function in the absence of carbohydrates, both physically and mentally. Instead of burning carbohydrates, or converting protein to glucose, the body burns ketones. This is pretty much a survival mechanism. It allows your body to function in a state of caloric deprivation. This is why ketosis often gets bad press (as it’s linked to “starvation”). Being a survival mechanism doesn’t make it invalid as a strategy, though. There can still be potential benefits to be had. Let’s cover a few of them… Ketosis and Accelerated Fat Loss Being in ketosis Continue reading >>
What Will Happen If I Don't Eat Carbs For 3 Weeks?
In 2012, I wanted to lose weight extremely fast. I had been weight lifting for about a year and I had put on some muscle as well as some fat due to poor dieting choices. This is a photo from 2015 but it’s similar to what I looked like in 2012. Not majorly overweight, but chubby. So, I decided to try and find the shortest way possible to get ‘shredded’. I wanted to look like Zyzz (below). I read somewhere online that to lose body fat, Zyzz would go on a ketogenic diet. I Googled some more and found details about what a ketogenic diet was. After minimal research I discovered that many people had lost weight using a similar approach. I was excited, I had found the method I was going to use to lose weight. My searching told me that a ketogenic diet involved eating practically 0 carbs. So I cut every single source of carbohydrates out of my diet. I said so long to my beloved sweet potato, rice, bread, fruit, everything. I also was led to believe that fat was evil when trying to lose weight, so I cut all of what I knew were sources of fat out of my diet too. So now nuts were gone, milk, cheese, oils. What was even left? A diet of minimal fats or carbohydrates… So my food sources at this stage was practically meat and green vegetables. More specifically chicken and broccoli. No sauce. Nothing else. Every meal. This meal looks 10x better than what I was having. See that sauce on the chicken? Not on my meals. I went extreme. I would tell myself, “It’s only four weeks.” What happened next? I felt terrible. I had little to no energy. My daily existence was fuelled by caffeine and pre-workout supplements (more caffeine). I was not doing a proper ketogenic diet at all… I didn’t understand it at the time. I was eating lean meats and green vegetables, how could I be Continue reading >>
7 Signs You Might Be In Ketosis When Doing The Ketogenic Diet
One of the main goals of starting the ketogenic diet is to get your body into a metabolic state known as ketosis. Note: If you don’t know what the ketogenic is all about then check out the Ketogenic Diet: Beginner’s Guide to Keto and Weight Loss. This is when your body starts to produce a lot of ketones to supply energy for your body. Why is this good? Because it means your body has converted from a sugar-burner to a fat-burner. If your body is burning fat for energy then something amazing starts to happen. The fat on your body starts to disappear. But how do you know when you’re in ketosis? Besides using test strips or an instrument there are some signs that your body will give. 7 Signs You Might Be in Ketosis These don’t 100% guarantee that your body is in ketosis but if it is in ketosis then these signs will appear. 1. Weight Loss One of the obvious signs of ketosis is weight loss but this can also be pretty deceptive because many people don’t experience the kind of weight loss that they expect. This can happen for a variety of reasons but when you get close to entering ketosis or do enter ketosis you’ll find that you lose a healthy amount of weight quickly. For example, when you switch to low carbs you usually experience significant weight loss in the first week. In fact, my wife lost 12 lbs in the first 28 days of Keto and I lost 13. This isn’t your body burning fat but finally being able to release the water that was being held by the fat cells. If your fat cells don’t release this water then they can’t flow through the bloodstream to be used as fuel so losing water weight is a good thing. After the initial rapid drop in water weight, you should continue to lose body fat consistently if you are able to stick with the low-carb aspects of the diet Continue reading >>
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 >>
Does Starving Only Lead To Loss Of Water Weight Or Muscle Mass Instead Of Fat Loss?
WHAT HAPPENS WHEN YOU STARVE YOURSELF? This will be a long one, but I think it's important to clearly delineate the starvation process instead of relying on blurbs from the internet To answer the question directly, starving yourself will lead to fat loss at first, then muscle and water loss, then fat loss again, then death. To explain why, let's do a breakdown of what happens when you stop eating starting from your last meal. You've just taken your last bite of food. Your saliva enzymes start breaking it down. It goes down your esophagus. Your stomach acid and enzymes break it down further into chyme which is a partially digested mass of food-like product that is small enough to enter into the intestine. Your gall bladder, pancreas, and small intestine produce more enzymes to further break the food down into it's separate components, different enzymes and compounds are secreted to break down food based on it's content.  Additionally, foods are broken down by your gut microbiome, or bacteria. The bacteria in your gut will eat the food you provide it and excrete it in a different form, which may be absorbed by your body.    When it's small enough, the various nutrients are either absorbed into your intestinal lining and sent to the liver, sent into the bloodstream, metabolized by your gut flora, or sent down through your large intestine where the water is removed and you're left with feces. In any case, your blood sugar and nutrient contents go up after you eat. Food can't just enter your cells, however. They need transport mechanisms that know how to pass things through your cell lining. Lipoproteins (LDLs) shuttle fatty acids to cells, and insulin lets glucose and amino acids into the cells. Insulin levels will rise as your blood sugar rises. About half o Continue reading >>
What Is It Like To Go On A Ketogenic Diet?
It's do-able. Some people love it and some people hate it. Personally, I find that nutritional ketosis is almost ideal for me, whereas "normal" eating with lots of carbs in my diet leads to feelings of non-satiety, drowsiness, mood swings, insulin spikes, bloating, and sometimes nausea. A ketogenic diet consists of 70-80% calories from fat, 15-25% calories from protein, and 0-5% calories from net carbohydrates (carbs). You must restrict your daily net carbs to 20-40g daily. (total grams carbs) - (grams fiber) = (net grams carbs) Your transition period depends on a few factors: how strictly you limit your carbohydrate intake, how much energy you expend day-to-day, and how much energy in the form of glucose and glycogen you have stored in your body currently. My transition period takes 3 days. Day 1: This is an easy day. Your blood is still filled with circulating glucose, and any deficit will be taken from the glycogen in your liver to be converted to glucose. You may feel hunger pangs by the afternoon, and a small dip in insulin, which will feel normal to you because this is what happens every day on a normal diet and you are used to it. Day 2: This is an easy day, too. Your body is happily pulling glycogen from your liver, converting it to glucose, and all is well. Any small amount of carbs that you consume are burned away, nothing is being stored. You may feel the typical afternoon slowdown and hunger, as on day 1. Day 3: Hard day. Your body has been (or is nearly) depleted of glucose and glycogen. The small amount of carbs that you consume are not enough to fuel your brain. You have a feeling of satiety from all the fat you are consuming, but you may feel achy, have headaches, and feel sluggish. Your body is alerting you to the lack of glucose and glycogen. It will t Continue reading >>
6 Things That Happen To Your Body When You Go On A Ketogenic Diet
By now, you've probably heard of the ketogenic diet, or a low-carb, high-fat diet. It’s a popular diet trend among athletes and average folk alike. (Who doesn't love the idea of eating more steak and bacon?) But what actually happens to your body when you go on the ketogenic diet? To understand how the ketogenic diet works, you have to understand ketosis, the process by which your body is starved of glucose for fuel and must look to fat sources instead. Typically, you fuel your body by giving it glucose in the form of carbs, which can be found in flour, grains, vegetables, legumes, dairy products, and fruits. We usually introduce a steady stream of this type of fuel into our bodies with each meal or snack, explains Pamela Nisevich Bede MS, RD, CSSD, LD. These carbohydrates are usually the body’s first choice when looking for an instant fix. “When a carb is available, the body will naturally turn to this to make energy instead of dietary fat or stored body fat. However, when we remove carbohydrates from our diet, our bodies begin to break down fat and turn to a fuel source in the form of ketones, which is more efficient but generally underutilized,” explains Bede. Rob Gronkowski's Diet: This is a modal window. Beginning of dialog window. Escape will cancel and close the window. End of dialog window. Ketones are a substance produced by the liver when the body breaks down fat for energy, which are then released into the blood. Your body's cells use ketones to power everyday activities. When there’s a buildup of ketones in the blood and you’re switching gears into an ketogenic state, your body changes in some incredible ways. 1) Your insulin levels drop. On a normal diet, after eating glucose-containing foods, your insulin levels will be higher. But when you’r Continue reading >>
7 Things That Will Happen To Your Body When You Start A Keto Diet
Ketogenic diets are trending at the moment and perhaps by now, you’ve heard of the low-carb, high-fat regime being followed by athletes and the general population alike. But what exactly does it mean? Be Fit Food co-founder and practising accredited dietitian Kate Save explains ketosis as a metabolic state in which our body produces ketone bodies as an alternative energy source to glucose. “The body's preferred fuel source is glucose which you largely consume in the form of carbohydrates found in breads, cereals, grains, legumes, fruit, starchy vegetables and dairy products and sugar,” explains Kate. “But if you only consume a very low amount of carbohydrates and boost your fat intake levels, your body begins to look elsewhere for fuel which is where ketone bodies come into the equation; you start to burn ketones rather than glucose.” RELATED: Exactly How Many Grams Of Carbs You Should Eat Per Day If You’re Trying to Lose Weight One of the key benefits of using ketones for energy – and what often yields weight loss results – is that the body no longer relies on dietary intake and instead uses stored fats for fuel. “There is also a state called ‘mild nutritional ketosis’ which is just as it sounds, a milder state of ketosis which is sustainable for longer periods and has fewer side effects due to its less extreme fat vs carb ratios,” she adds. So, taking all of this into account, what actually happens to your body when you are in a ketogenic state? Here are a few changes you’re likely to see. 1. You may feel tired and you might get sick … temporarily! The first few days of following a ketogenic diet are not much fun as your body is still looking for carbohydrates to burn. You may be hungry, low in energy, a bit irritable, more likely to get si Continue reading >>
What Is Ketosis? Hint: It Can Help You Burn Fat & Suppress Your Appetite
We’ve longed been told that calorie restriction, increasing exercise and reducing dietary fat intake are the keys to weight loss. But, if you’ve ever attempted to control your weight by subsisting on fewer calories — especially from mostly bland “diet foods”— you’re already probably aware that this typically produces minimal results and is extremely hard to stick with long-term or consistently. Considering the high rates of obesity now facing most developed nations — along with an increased risk for health conditions like diabetes or heart problems as a result — researchers have been anxiously working on how to suppress appetite and achieve weight loss in a healthy, sustainable manner. The keto diet has emerged over the past several decades as one potential answer to this large-scale weight loss problem. (1) While there are some differences in opinion, depending on who you ask, regarding the best approach to very low-carb dieting, studies consistently show that the ketogenic diet (also called the keto diet) produces not only substantial weight loss for a high percentage of people who adhere to it, but also other important health benefits such as reductions in seizures, markers of diabetes and more. The keto diet revolves around eating foods that are high in natural fats, consuming only moderate protein and severely restricting the number of carbs eaten each day. Even if you don’t have much weight to lose, entering into a state of ketosis can be helpful for other reasons — such as for improved energy levels, mental capabilities and mood stabilization. What Is Ketosis? Ketosis is the result of following the ketogenic diet, which is why it’s also sometimes called “the ketosis diet.” Ketosis takes place when glucose from carbohydrate foods (like Continue reading >>
Why Is Belly Fat So Hard To Lose In Adults?
In this article, I’ll explain first why belly fat is so hard to lose, and then explain how to lose it. The tl;dr is that it is a combination of: caloric restriction (no more than 25% deficit while keeping protein intake per day at at least 1gm/lb of bodyweight; the ratio of carbs to fat is largely irrelevant although if you weightlift you’ll want to eat more carb calories than fat calories) avoid foods with added sugar whenever possible (fruits are fine because the sugar in fruits takes a long time to digest), the discipline to stick to the program. The above is necessary. However, if you just do the above, the belly fat will come off at the very end. If you want to also lose belly fat during your dieting, then you should also do: intermittent fasting, high intensity exercise while deeply fasted (BCAA supplements may help reduce lean mass loss but the science isn’t conclusive); HIIT or HIRT (with heavy weights low reps or light weight high reps) supplements that specifically target belly fat like yohimbine or preferably rauwolscine taken while fasted. Discipline is key and is why most people fail. It’s a long process with most of the belly fat only coming off at the very end. You must keep to your deficit (eat normally at least once a week), track your calories (by eating pre-planned meals or by using FatSecret app) and avoid foods with added sugar. If you give in to temptation (over eat or indulge in a sugar binge), you’ll make a long process even longer. I recently ran across an excellent video on YouTube on losing belly fat that is 100% consistent with my research. It’s short and to the point. Watch it, then for best results, come back here for a deeper understanding. The techniques above work for stubborn fat on women as well as for men (the lone excepti Continue reading >>
How Would The Human Body React To Near-instant Fat Loss In A Morbidly Obese Person?
OK since this is a hypothetical question, let’s suppose that somehow there was a way to remove all of the fat in your body instantaneously by some magical means. This way it’s totally safe and you don’t die from blood loss or shock. So one sunny day you’re trudging along on the sidewalk talking to your friends about what to have for lunch. Then suddenly a fairy comes around and completely removes all your fat. But the fairy doesn’t worry about how your body will adjust, only that she removes all your fat without killing you. Since you still have muscles which was responsible for moving 50+ pounds of extra fat in your body, the first thing you will notice is how light you are! If you were in the middle of walking when the instantaneous fat removal happened, it may even cause you to become off balance and trip over yourself! But once you look down and feel your new body, the next thing you will notice is just how much loose skin you have. This is more or less how you will look like: And as the other posters here have stated, afterwards you may experience extreme lethargy and depression due to the hormonal imbalance resulting from the missing fat cells. So what did we learn here? Fat loss is complicated and is definitely not so cut and dried. Just because you can rapidly lose fat does not mean you will end up with a “hot-bod.” People don’t consider how difficult it is to get rid of saggy skin after rapid weight loss. The key here is that weight loss should never be instant or rapid. Weight loss equates to healthy lifestyle and active living which means it is a lifetime commitment. There are no short cuts and attempting to do so tends to produce inferior results. Never try to cut corners. There are people who lost 100+ pounds over a few years and end up with Continue reading >>
Ketosis, Ketones, And How It All Works
Ketosis is a process that the body does on an everyday basis, regardless of the number of carbs you eat. Your body adapts to what is put in it, processing different types of nutrients into the fuels that it needs. Proteins, fats, and carbs can all be processed for use. Eating a low carb, high fat diet just ramps up this process, which is a normal and safe chemical reaction. When you eat carbohydrate based foods or excess amounts of protein, your body will break this down into sugar – known as glucose. Why? Glucose is needed in the creation of ATP (an energy molecule), which is a fuel that is needed for the daily activities and maintenance inside our bodies. If you’ve ever used our keto calculator to determine your caloric needs, you will see that your body uses up quite a lot of calories. It’s true, our bodies use up much of the nutrients we intake just to maintain itself on a daily basis. If you eat enough food, there will likely be an excess of glucose that your body doesn’t need. There are two main things that happen to excess glucose if your body doesn’t need it: Glycogenesis. Excess glucose will be converted to glycogen and stored in your liver and muscles. Estimates show that only about half of your daily energy can be stored as glycogen. Lipogenesis. If there’s already enough glycogen in your muscles and liver, any extra glucose will be converted into fats and stored. So, what happens to you once your body has no more glucose or glycogen? Ketosis happens. When your body has no access to food, like when you are sleeping or when you are on a ketogenic diet, the body will burn fat and create molecules called ketones. We can thank our body’s ability to switch metabolic pathways for that. These ketones are created when the body breaks down fats, creating Continue reading >>
Doctor Explains What Happens To The Human Body When It Goes Into Ketosis (ketogenic Diet)
From a young age we’re taught that eating three meals a day, plus snacks, is healthy and necessary for the human body to function normally, and this rhetoric still dominates North American food guides today. Mark Mattson, the Current Chief of the Laboratory of Neuroscience at the National Institute on Aging, once asked: Why is it that the normal diet is three meals a day plus snacks? . . . There are a lot of pressures to have that eating pattern, there’s a lot of money involved. The food industry – are they going to make money from skipping breakfast like I did today? No, they’re going to lose money. If people fast, the food industry loses money. What about the pharmaceutical industries? What if people do some intermittent fasting, exercise periodically and are very healthy? Is the pharmaceutical industry going to make any money on healthy people? The quote above comes from a TED talk Mattson gave on the benefits of fasting, a practice which forces the body to switch its fuel source from glucose to ketones. Scientists are observing a wide variety of health benefits from this transition, from starving cancer to improving cognition, and a ketosis diet is now being implemented for people with cancer, Alzheimer’s disease, epilepsy, and more. It has tremendous benefits for the brain, as explained by Mattson in his talk, but also for the body. What Is Ketosis? The human body only has two fuel sources, fat and glycogen (sugar). When we have a lot of sugar stored in the body (from consuming carbohydrates, for example, which turn into sugar), our body uses that sugar to feed our brain and other organs, providing the energy they need to function. When the body runs out of glucose, it switches energy sources, from glycogen to fat. This can only happen when the body is de Continue reading >>
10 Signs And Symptoms That You're In Ketosis
The ketogenic diet is a popular, effective way to lose weight and improve health. When followed correctly, this low-carb, high-fat diet will raise blood ketone levels. These provide a new fuel source for your cells, and cause most of the unique health benefits of this diet (1, 2, 3). On a ketogenic diet, your body undergoes many biological adaptions, including a reduction in insulin and increased fat breakdown. When this happens, your liver starts producing large amounts of ketones to supply energy for your brain. However, it can often be hard to know whether you're "in ketosis" or not. Here are 10 common signs and symptoms of ketosis, both positive and negative. People often report bad breath once they reach full ketosis. It's actually a common side effect. Many people on ketogenic diets and similar diets, such as the Atkins diet, report that their breath takes on a fruity smell. This is caused by elevated ketone levels. The specific culprit is acetone, a ketone that exits the body in your urine and breath (4). While this breath may be less than ideal for your social life, it can be a positive sign for your diet. Many ketogenic dieters brush their teeth several times per day, or use sugar-free gum to solve the issue. If you're using gum or other alternatives like sugar-free drinks, check the label for carbs. These may raise your blood sugar levels and reduce ketone levels. The bad breath usually goes away after some time on the diet. It is not a permanent thing. The ketone acetone is partly expelled via your breath, which can cause bad or fruity-smelling breath on a ketogenic diet. Ketogenic diets, along with normal low-carb diets, are highly effective for losing weight (5, 6). As dozens of weight loss studies have shown, you will likely experience both short- and long Continue reading >>
