What is INSULIN RESISTANCE? What does INSULIN RESISTANCE mean? INSULIN RESISTANCE meaning - INSULIN RESISTANCE definition - INSULIN RESISTANCE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. Insulin resistance (IR) is a pathological condition in which cells fail to respond normally to the hormone insulin. The body produces insulin when glucose starts to be released into the bloodstream from the digestion of carbohydrates in the diet. Normally this insulin response triggers glucose being taken into body cells, to be used for energy, and inhibits the body from using fat for energy. The concentration of glucose in the blood decreases as a result, staying within the normal range even when a large amount of carbohydrates is consumed. When the body produces insulin under conditions of insulin resistance, the cells are resistant to the insulin and are unable to use it as effectively, leading to high blood sugar. Beta cells in the pancreas subsequently increase their production of insulin, further contributing to a high blood insulin level. This often remains undetected and can contribute to a diagnosis of type 2 diabetes or laten

What Is Insulin Resistance? | Real Meal Revolution

Posted at 11:34h in by Real Meal Revolution Insulin resistance is a condition whereby the cells of your body dont respond properly to the hormone insulin. It is directly associated with type 2 diabetes, gestational diabetes,prediabetes and obesity, however, one can be insulin resistant without being obese. Insulins job is push blood sugar (glucose) into the cells (any cells) to be used as fuel. Once the cells have been fuelled, insulin pushes the remaining blood sugar to the fat cells to be stored as back-up fuel (fat). In a healthy person, most of the blood sugar would be burned up in a short period of time which would reduce the need for your body to store any of it as fat. In the case of is insulin resistance, the cells resist the insulin and essentially reject the fuel that is on offer. As a response, the body then produces more and more insulin, supposedly to try and force the blood sugar out of the blood and into any cells that will take it (pretty much only the fat cells). This ends in too much insulin flowing through the blood which is called hyperinsulinemia (too-much-insulin-itis), and it comes with a bouquet of nasty symptoms like: The three most important symptoms in t Continue reading >>

    I'm confused about what defines being in nutritional ketosis based on blood levels. The Diet Doctor website says 1.5 is considered ketosis while I've heard on Keto Talk from Doc Nally that fit and active people can be in ketosis at levels of .3 or .4 and that higher levels don't necessarily mean better. So I'm not sure what the heck I'm aiming for! If I get readings below 1.5 am I doing something wrong? I am fit and active and Doc Nally has said this can make blood ketone level readings lower because an active persons body is using the ketones more efficiently. Should I be aiming for higher levels?

    It seems that the longer someone is keto-adapted, the more their body produces just the right amount of ketones and what we measure in the blood is only what's not actually being used, therefore it seems not only possible, but likely that people are in ketosis even with lower betahydroxybutyrate (BHB) levels - the ketone in the blood that these meters measure.
    This is somewhat frustrating for me since I'd like for there to be an objective measurement of being in ketosis, but that seems to be elusive.
    Therefore, a better indication is your level of carbs since it is HIGHLY unlikely that anything over 50 carbs is in ketosis and more likely that keeping carbs under 20 grams is a safe bet. Another indication is keeping protein at moderate levels which is 1.0 to 1.5 grams per kilogram of lean body weight.
    Once the macro-nutrients are in the proper range, I think that signs of keto-adapation are more poignant and below is a post from Mark Sisson on Dr. Mercola's site that explains many of the signs of being keto-adapted.

    What Does It Mean to Be Fat Adapted?

    Dr Phinney invented the term so he gets to define it.
    In his book "The art and science of low carbohydrate living" he gives the range from 0.5 to 3.0 mmol/l
    But recently he mentioned that some of Dr Volek's very athletic subjects were clearly in ketosis at 0.2 mmol/l.
    My personal range is from 0.2 to 0.8 mmol/l, and I have been in ketosis for almost 3 years. Prof Tim Noakes is also normally in the same range 0.2-0.8.
    I suspect when we first start we aren't good at using them so we make too many and use too little so we end up with a lot left in our blood. After we become better adapted we end up in whatever physiological range our bodys feel best ensures our survival. And people who are trained and good fat burners may be able to get away with less because they can make it easily.
    When I fast for 3 days and then do 3 hours of exercise my ketones can go as high as 3.5. But I know people who regularly get up to 7.
    It's worth pointing out that Dr Nally has mentioned in his most recent podcast that he eats exogenous ketones 3 times a day. And he sells them.

    Personally I wouldn't be worried. I think you are doing fine.

Insulin Resistance | Fat Loss At Fifty

How the Low Carb, High Fat Lifestyle Rescued Me from My Genetic CurseDiabetes Earlier this month, Brian, my life partner shared his story with you. He was able to turn his health around. More importantly, he has added many years to his life. But Im the lucky one because I get to spend those years with him. One of the people who helped to keep Brian motivated was his good friend, Steve. I think it made things easier at work, having someone else who was living a low carb lifestyle. These men are an absolute inspiration and I am very proud of them! I asked Steve if he would share his testimony with my readers. Below is his story.

    Your first, best, and cheapest option is not to use them.
    Ketostix do not measure what many people expect that they do.
    Ketostix only measure excess levels of acetoacetate, which is not the type of ketones that correlate with nutritional ketosis.
    Ketostix may show negative ketones when your blood ketones are high and then may show positive ketones when your blood ketones are low.
    Misinterpretation of what they show is one of the most common unnecessary causes of keto anxiety and wasted time. You can be perfectly successful on a ketogenic or low-carb diet without ever measuring ketones.
    Many people are already overwhelmed with learning about keto diets. Adding another layer of unnecessary complexity doesn't help the matter. Often, people are most successful on keto when they treat it as a lifestyle and not a diet. Obsessively measuring ketones can be at odds with attempting to live a keto lifestyle.
    If you decide to use Ketostix anyway, please be kind to those who answer questions here by not submitting a question that begins with I know that Ketostix are unreliable, but ...
    If you consume few enough carbohydrates and avoid excessive intake of protein, you can trust that your liver will be producing ketones within a single day. That is how human metabolism works.
    If you consume too many carbs, you will be kicked out of ketosis temporarily. However, if you once again restrict carbs, you will go right back into ketosis within 24 hours. This is because the liver can store only 100 grams of glycogen. If you restrict carbs, the liver will run out of glycogen within a day and begin burning fat instead. The liver produces ketones as a side effect of burning fat.
    As an example of how Ketostix can be misleading, it is possible to eat a high-carbohydrate meal followed by a positive Ketostix result. You may think that you cheated the system, but you didn't. It takes time for excess ketones to appear in urine. Ketostix are showing you what happened in the past before you cheated.
    If you have the time and really want to know why Ketostix will not tell you much, read pages 164 and 165 of The Art and Science of Low Carbohydrate Living by Volek and Phinney. This is the section headed by Ketones: To Measure or Not.
    If you do not have this book, read this summary:
    http://ketopia.com/why-you-need-to-stop-worrying-about-the-color-of-your-ketostix/
    Ketostix were designed to help diabetics avoid ketoacidosis which is a dangerous condition involving very high blood sugar and very high serum ketones. If you have near normal blood sugar and serum ketone levels consistent with nutritional ketosis, you don't need to worry about this.
    Ketostix only measure excess levels of acetoacetate, which is not the type of ketones that correlate with nutritional ketosis.
    The ketones that correlate with nutritional ketosis are known as beta-hydroxybutyrate. This type can be measured only with a blood ketone meter.
    There is a built-in time lag. Ketostix are measuring what has happened in the past since it takes a while for the kidneys to produce urine.
    Exercise can influence how many excess ketones are excreted.
    You can be in nutritional ketosis even when Ketostix show no excess acetoacetate. In the keto-adapted state, very little acetoacetate ketones will be excreted in urine even though blood ketones may be high.
    Note that it takes a period of four to six weeks of being in ketosis every day in order to become keto-adapted. Someone who is keto-adapted has adapted to using fat as the primary fuel for muscles and various organs. The keto-adapted brain uses ketones in place of glucose for most of its energy needs. When keto-adapted, most acetoacetate is not excreted. Instead, muscles convert it to beta-hydroxybutyrate and return it to the blood for use by the brain.
    If after all of this, you still want to use Ketostix because you bought them and cannot bring yourself to throw them away or because they are comforting in some way, here is how they may be useful.
    When you are first starting a low-carb or keto diet and transitioning into ketosis from a moderate to high-carb diet, Ketostix will confirm that your body has in fact done what biology says that it must do. It will show that your liver has begun producing ketones.
    Once you are a few days into the diet, you can give them away to a keto newbie or toss them. Note that Ketostix will eventually expire, especially if you keep them in a moist environment like a bathroom.
    If you have a medical condition that makes monitoring blood ketone levels necessary or if you are a numbers geek with spending money, you may be interested in purchasing a ketone blood meter and test strips for measuring beta hydroxybutyrate in your blood. The test strips cost somewhere between $2 and $5 per strip.
    There are a few meters to choose from.
    Precision Xtra - https://www.abbottdiabetescare.com/products/patient/pxtra-overview.html
    Nova Max Plus - http://www.novacares.com/nova-max-plus/
    CardioChek Home - http://www.healthchecksystems.com/CardioChek.cfm#home
    Most use one of the first two listed (Precision Xtra or Nova Max Plus). Some say that the Precision Xtra is the more accurate of the two. I've found that readings from these two track fairly closely with each other. The Nova Max Plus has cheaper test strips.
    To detect nutritional ketosis, look for a reading between 0.5 and 5.0 mmol / liter. Some experts recommend aiming for a level of 1.0 to 5.0 mmol / liter.
    Another option is the Ketonix Sport breath meter. This meter measures acetate in the breath. It does not require test strips.
    Acetate forms when acetoacetate spontaneously breaks down to acetate. According to Volek and Phinney (page 165 of The Art and Science of Low Carbohydrate Living), it should be linearly correlated with blood ketones. In practice, it is not as accurate as the blood meters in part because it is difficult to breathe in the same way every time you test.
    Ketonix Sport (order direct from Sweden) - https://www.ketonix.com/index.php/product/sport
    Again, remember that you can be perfectly successful on a ketogenic or low-carb diet without ever measuring ketones whether in urine, blood, or breath.
    In the final analysis, ketone concentrations are what they are. Chasing ketone concentrations often becomes as unnecessary and distracting as Ketostix. Unless you are treating epilepsy, cancer, or other medical condition, the concentration of ketones do not matter too much. You can achieve weight loss and a sense of well-being even with lower levels of ketones.
    Focus on how you feel, not on the number. Use ketone meters for interest and experimentation, but don't let the results stress you out.
    tl;dr never, unless you have read and understood this post, yet still want to use them anyway
    [If anyone has any suggestions for improving this post or correcting misinformation, let me know. I'll correct this and re-post it once in a while]

    Hallelujah!!
    tl;dr never
    If you want to do it for experimentation, go for it but please spare the rest of us the unnecessary ketosis anxiety
    edits: In addition to false negatives, ketostix commonly show false positives as in when people eat a high carb meal and think they cheated biology. Also I might remove the bit about using ketostix to monitor keto-adaptation, just asking for more posts about the issue. Also I might emphasize that people seem to already be overwhelmed with keto when starting and adding another layer of unnecessary complexity doesn't help the matter. People always talk about lifestyle, live a lifestyle and IMO living a lifestyle certainly shouldn't have to include measuring. Lastly, ketone concentrations are what they are. If you want to measure with a blood or breath meter, they are what they are and chasing ketone concentrations often becomes as unnecessary as ketostix. Unless someone has a medical condition for which a particular concentration is required for management, focus on how you feel not the number. Use the meter for interest and experimentation, but don't let it stress you out.
