Pruvit Keto Os Exogenous Ketones Review – Miracle Supplement?

Pruvit Keto Os Exogenous Ketones Review – Miracle Supplement?

Pruvit Keto//OS Ketone Operating System Review Hello! Hi, my name is Rachel Vrabel and you can find me on Instagram @womensblogtalk or on Facebook. Today I’m reviewing a supplement made by Prüvit called Keto//OS (Ketone Operating System), which is a powder you mix with water and drink once or twice daily that tastes delicious! Keto OS puts your body into a fat burning state of ketosis within 30 minutes by flooding your body with exogenous ketones. The skinny is – you’re burning FAT rather than carbs. Good for weight loss? Heck yes! And extremely safe. But what’s even more amazing is how you FEEL (remember that, because ketones are NOT just a fat loss aid, that’s just side effect of being in ketosis!) Remember the Atkins Diet – high fat, low carb? It’s a tough diet to follow, but one that works to shed weight quickly if you can endure the food restrictions. A similar diet is the Ketogenic Diet which is a high fat/moderate protein/low carb diet and there are plenty of restrictions. But what if you don’t want to follow a strict diet but you still want the benefits of being in ketosis? This is where Keto//OS sets itself apart from every other supplement on the market! Here are some of the benefits of ketosis and drinking Keto OS: Fat loss Sustained energy Increased focus Suppressed appetite Better mood Better sleep Muscle preservation Anti-aging, clearer skin Please, keep scrolling for information on each of the flavors! But first I’d like to tell you about my Pruvit Keto-OS Results! Check out my Youtube Video Review on Keto OS How Much Weight Have I Lost on Keto OS? Keto OS Before and After Photos – Results from Drinking Keto OS Round #1 (Jan. 2016) Ok so I’ve had two rounds with losing weight on Keto OS and I want to tell you about both times, becau Continue reading >>

Common Ketosis Killers

Common Ketosis Killers

“I’ve tried your low-carb diet, Dr. Nally, and it didn’t work.” “Hmm . . . really?” If your mumbling this to yourself, or you’ve said it to me in my office, then lets have a little talk. I’ve heard this statement before. It’s not a new statement, but it’s a statement that tells me we need to address a number of items. If you’ve failed a low carbohydrate diet, I’d suspect you are pretty severely insulin resistant or hyperinsulinemic. You probably never really reached true ketosis. I’d want to have you checked out by your doctor to rule out underlying disease like hypothyroidism, diabetes, other hormone imbalance, etc. Next, switching to a low-carbohydrate lifestyle is literally a “lifestyle change.” It requires that you understand a few basic ketosis principles. And, it takes the average person 3-6 months to really wrap their head around what this lifestyle means . . . and, some people, up to a year before they are really comfortable with how to eat and function in any situation. I assume, if you are reading this article, that you’ve already read about ketosis and understand the science behind it. If not, please start your reading with my article The Principle Based Ketogenic Lifestyle – Part I and Ketogenic Principles – Part II. If this is the case, then please proceed forward, “full steam ahead!” There are usually a few areas that are inadvertently inhibiting your body transformation, so let’s get a little personal. First, this is a low carbohydrate diet. For weight loss, I usually ask people to lower their carbohydrate intake to less than 2o grams per day. How do you do that? (A copy of my diet is accessible through my membership site HERE.) You’ve got to begin by restricting all carbohydrates to less than 20 grams per day. Continue reading >>

Will This Kick Me Out Of Ketosis?

Will This Kick Me Out Of Ketosis?

A common question people have when starting keto is “will this kick me out of ketosis?” I’m going to address as many items as I can think of and explain why it will or will not kick you out of keto. This is going to be as comprehensive as possible so either use ctrl + f to find what you’re looking for or buckle up and read on. How do humans enter ketosis in the first place? Things will become much more clear if we explain how humans enter ketosis. Mainly, liver glycogen is what determines if ketones will be produced. Specifically, glycogen in the liver signals malonyl-coa to be formed by carboxylating acetyl-coa. Acetyl-coa is used in many processes and it’s the main substrate used to be turned into ketones. The wiki on regulation of ketogenesis which applies to this scenario says “When the body has no free carbohydrates available, fat must be broken down into acetyl-CoA in order to get energy. Acetyl-CoA is not being recycled through the citric acid cycle because the citric acid cycle intermediates (mainly oxaloacetate) have been depleted to feed the gluconeogenesis pathway, and the resulting accumulation of acetyl-CoA activates ketogenesis.” Basically, when there is more acetyl-CoA than oxaloacetate, the acetyl-CoA becomes acetoacetate, a ketone body. In plain English, carbs provide oxaloacetate, so if it doesn’t have carbs, it likely isn’t going to kick you out of ketosis. I’ll state the exceptions later. Why do humans enter ketosis so readily? Humans enter ketosis faster than any animal on the planet. It usually takes 24-36 hours before we enter ketosis.This is because we have huge brains and tiny bodies. Our brains need ~400 calories/day, which for most people that equates to 20% of our total energy demands. To put this in perspective, most anim Continue reading >>

Avoid This Ketogenic Rip-off

Avoid This Ketogenic Rip-off

The Truth About Exogenous Ketones Ketones are all the rage among low carbers. And like most things in nutrition and performance, we've found a way to get them in supplement form so we don't have to do any actual work. What are ketones? They're a byproduct of ketosis caused by the process of converting fat to fuel. Your body makes them when it's in a calorie or carb restricted state. What do they do? The body and brain can use them as fuel without the presence of glucose in the blood. And now, you can take ketone supplements (salts and esters), known as exogenous ketones, without actually restricting anything. According to those promoting this nasty-tasting supplement, that means you can have a brain and body fuelled by ketones, along with all of the supposed health benefits that come with running on fat. Well, don't fall for it. Exogenous Ketones = Endogenous Fat Storage? The problem with ketone supplementation (EXOgenous) is that it's not even close to the same thing as being in ketosis (ENDOgenous ketone production). And just like the butter-blended-into-coffee trend, it's a farce. Ketones may be depressing dieters' hunger and giving them a hit of energy and cognitive enhancement, but it's INHIBITING their ability to burn fat, providing zero nourishment, and doing nothing for their metabolic health. There's an assortment of evidence suggesting that it's probably making things worse. Think of exogenous ketones kind of like alcohol. When they're consumed, everything is stored and nothing else is burned. So any lipolysis (fat burning) that would be taking place is halted; any glucose and fatty acids in your blood that were circulating are stored; and the ingested ketones are burned until there aren't any left. More importantly, this clearance of alternative fuels (glucos Continue reading >>

Does Caffeine (or Chocolate) Raise Insulin, Thereby Stopping Fat Burning (ketosis)?

Does Caffeine (or Chocolate) Raise Insulin, Thereby Stopping Fat Burning (ketosis)?

So caffeine and the stimulant in chocolate raises insulin. Insulin shuts down fat oxidation. So, if you are in ketosis, on VLC, won't drinking coffee or eating raw dark chocolate shut of that nice fat burning mode? I know when I am VLC, if I have ANY, I mean a few SIPS of tea or nibbles of cacao, I IMMEDIATELY get that "hormonally hungry" feeling. Any thoughts? EDIT So I've found that on meat/fat only days, in Ketosis, caffeine or stimulants of any kind make me feel terrible, and VERY hormonally hungry between meals (with the same timing and calories that on non-caffeine days are satiating). I literally can scarcely make it to my next meal, feeling utterly starved and losing all concentration. However, on carb-up days after exercise, I can eat some chocolate or drink some tea, and while I feel quite stimulated (perhaps too much, I seem to be sensitive), it isn't a bad feeling, and I don't get the hunger afterwards. Interesting. Continue reading >>

Increased Sensitivity To Caffeine From New Low Carb Diet?

Increased Sensitivity To Caffeine From New Low Carb Diet?

i have noticed something very strange since i started pursuing a ketogenic diet about a week ago. i have always considered myself immune to the effects of caffeine since i drank many cups of black tea and coffee a day for the past 8 or so years (growing up). since i started making an earnest effort to cut my carbs, pursue Primal eating, up my fat, and stabilize my blood glucose level, and lower my stress levels, my morning Bulletproof coffee is hitting me in a very unpleasant way the past few days: i feel overcaffeinated in a way that has only happened a few times in the past after drinking significant amounts of coffee. my stomach feels sick and my heart is racing and my body feels very edgy. i am wondering if this could be a good sign that i am lowering my cortisol level to a point where caffeine is actually increasing my cortisol to a measurable degree. i am eating a lot of butter and CO with my coffee (a 10oz cup each morning) i am going to start buying decaf now because i feel so icky after drinking my coffee but it is SO weird that i am suddenly exhibiting this because of my history of caffeine tolerance. edited to add: is there anything i can eat as an antidote to this overcaffeinated state???

11 Reasons You Are Not Losing Weight In Keto

11 Reasons You Are Not Losing Weight In Keto

An important part of a weight loss journey is realizing that it won’t happen overnight as it requires dedication, motivation, and effort. But, after a few weeks of months of sticking to a healthy low carb/ keto diet your scale decides to stop moving. Not seeing results may become frustrating and overwhelming. Here are a few tips & tricks that will help you get past your weight loss plateau. Here are 11 reasons why you stopped losing weight and how to get the situation under control. 1.SWEETENERS It’s fantastic to treat yourself with something sweet now and then. Sweeteners are safe to use for most of the people, but for some, it causes intense cravings for real sugar. As I love to experiment on myself first and then show my results, along with following strict ketogenic macros, I ditched all the artificial sweeteners from my diet for a few weeks (including diet sodas, which yeah I know contain aspartame that’s very harmful, but oh well, we’re humans). I can relate that I didn’t have sugar cravings anymore, my headaches were gone, and I dropped a few pounds even I didn’t want to. Every person reacts different at sweeteners, and I recommend you to limit your daily consumption and focus on real food. 2.TOO MANY CALORIES I know you’ve heard that on a low carb diet like a Ketogenic Diet and Atkins Diet you only have to stay under the daily limit of carbs and eat as much protein and fat as you can. Fat is twice more dense caloric than carbs, so therefore the calories add up quickly. No diet in the world recommends unlimited calories for weight loss. So if you are not losing weight, you should consider finding your ideal macronutrients (look online for a keto calculator) and stick with them, because calories matter even on a low carb diet. 3. NOT ENOUGH OR TOO MU Continue reading >>

Caffeine And Ketosis

Caffeine And Ketosis

by David Perlmutter, M.D., Board-Certified Neurologist, #1 New York Times Best-Selling Author, Fellow of the American College of Nutrition Typically, when you wake up in the morning after 12 hours of fasting, your body is in a state of what we call mild ketosis. This means that your body has shifted away from burning glucose as the only fuel source and is now tapping into your body fat reserves. When a person is in ketosis, it’s actually a very healthy state of affairs as it relates to brain function. Just go to your online bookstore and you’ll see so many new books being written with the theme of providing delicious recipes to maintain a state of ketosis. Indeed, the health claims of being in ketosis seem to be increasing on a daily basis. But it turns out that keeping your body in ketosis does in fact provide some health benefits. I will leave this discussion for a future post. But for now, I want to focus on the often raised question as to the effects of coffee consumption, or more specifically, caffeine consumption, on either enhancing ketosis or working against it. In a new study entitled, Caffeine intake increases plasma ketones: an acute metabolic study in humans, Canadian researchers evaluated the effects of caffeine consumption in a group of 10 volunteers. After fasting for 12 hours and then eating breakfast, these individuals were given either no caffeine, the equivalent of about a cup and a half of coffee, or a caffeine equivalent of 3 cups of coffee. Blood samples were then taken to evaluate not only the caffeine levels over a four hour period of time, but also the levels of ketones that were manufactured in the liver from the liberation of body fat. What the researchers found was indeed very compelling. Higher dosages of caffeine in the 10 healthy adult Continue reading >>

Does Green Coffee Bean Extract Help You Lose Weight?

Does Green Coffee Bean Extract Help You Lose Weight?

Green coffee bean extract has been marketed and has become one of the top selling weight loss products in recent years and with good reason. The health benefits of green coffee bean extract are real and can improve both mental and physical performance. The question is, does green coffee bean extract help you lose weight? Coffee is a major commodity enjoyed worldwide and one of the greatest sources of antioxidants found in people’s diets today. This caffeinated beverage has unfortunately been labeled harmful food due to the negative health associations with caffeine. The impact of caffeine on every person is different and can pose a serious health hazard to some while others tolerate caffeine well. Not as unhealthy as once though, polyphenols are a class of antioxidants contained in coffee and coffee can be seen as a very healthy beverage when regularly consumed. Two Major Classifications of Coffee The two major categories of coffee plants are Robusta and Arabica. The Arabica coffee plant is highest in the polyphenols chlorogenic and caffeic acid. These antioxidant properties makes Arabica coffee one of the best coffee types. Unfortunately, the process of roasting coffee reduces the antioxidant content of the finished coffee product and most coffee drinkers are not receiving these health benefits (3). Green coffee beans however are coffee beans that have not been roasted and are packed with antioxidants. (1, 5) In fact, green coffee bean extract is highly bioavailable in humans. Clinical studies have shown that antioxidants with impressive anti-inflammatory effects on the body are present in green coffee extract and readily absorbed. The two major types of chlorgenic acids found in nature, caffeoylquinic acids (CQA) and dicaffeoylquinic acids (diCQA), are primarily res Continue reading >>

Pruvit Keto Os Review

Pruvit Keto Os Review

We wanted to get to the bottom of things with Keto OS. Right off the bat there was an outpouring of negative reviews on taste, making our team jump straight into the ingredients. Then we noticed a rash of comments about side effects, which was enough to make us tackle the science head on. We took the information we found, summarized it, and now share with you – the truth about Keto OS. What is Keto OS? Pruvit Keto OS supplement is a powdered drink offering weight-loss support. If this drink is as terrible as some of the customer comments make it out to be, we have a hard time believing that anyone is seeing results. Before we get into the ingredients, according to the company itself, they can cause side effects. “Supplementing with KETO//OS or following a ketogenic diet can cause a slightly diuretic effect, and can deplete magnesium, potassium and sodium stores.” And that wasn’t all. Before we get ahead of ourselves, here are the Keto OS ingredients: MCT Powder Beta-Hydroxybutyrate Stevia Keto OS Max offers the same, but l-leucine, l-taurine, and a few others are added. Just one scoop or packet a day is supposed to force you into ketosis [2], so your body burns fat instead of carbs. This idea is what low-carb diets are based on. Ketosis is not to be confused with ketoacidosis, a medical condition that can be life-threatening. Pruvit, the makers of Keto OS, started online in 2013. You have various options to choose from on the official website including a canister of powder or prepackaged servings, which makes the Keto OS diet plan a bit easier. We like the addition of caffeine but that’s not the best part.

“you Have Literally Saved My Life”

“you Have Literally Saved My Life”

Here’s an impressive life transformation story, from Gareth Hicks: The Email Hej Andreas! Thanks for such an inspirational site! I was informed by my doctor at the end of 2012 that I needed to make some significant changes to my life – as I was nearly 44 lbs (20kg) overweight – and had a very poor fasting lipid profile. This coupled with high blood pressure (routinely 160/120) and little exercise, I was classified as a 15% daily risk of heart attack – and was racing towards CVD. As someone with a history of family heart disease, I knew I needed to do something different! As of tomorrow, 19th Feb, I will have been living a Low Carb High Fat lifestyle for one year. I have lost (and easily kept off) 35 lbs (16 kg) so far – by living on real food – with lots of fats added to make it extra tasty. I have completely removed pasta, most bread (I occasionally use unleavened bread with curry), have almost completely removed sugar – and live on a diet that is mostly curry, cauli-rice and fresh vegetables washed down with a glass of extra dry cava. I have inspired lots of people in the UK to adopt a lchf lifestyle, based on you – and your website – and am currently helping about 20 people on a one-to-one basis, as well as several others via Facebook. I’m a follower on twitter and Facebook – as well as the original DietDoctor.com website – and have created my own interpretation based on what I have learned from you – @curryandcava, www.curryandcava.com (still being developed) and on Facebook – curryandcava.com ;) Many people in the UK are desperate for this type of information – so please keep it coming – and I will keep sharing it !! Please also feel free to have a look at the pages and feedback anything you’d like to highlight! I have done extensi Continue reading >>

5 Reasons Diet Soda Could Be Stalling Your Low-carb Diet Weight Loss

5 Reasons Diet Soda Could Be Stalling Your Low-carb Diet Weight Loss

Low carb diets are designed to burn body fat by putting the dieter into benign dietary ketosis. To enter into a state of ketosis, most people will have to eat less than 40 grams of carbohydrates per day. Low-carb diets not only shed body fat pounds, they also shed tremendous amount of water weight and deplete the liver and body of glycogen reserves, a form of stored energy. Anything that messes with your fluid balance or knocks you out of ketosis can cause a stall in weight loss — or worse, weight gain. Here are five ways diet drinks can sabotage your best low-carb efforts: 1. Caffeine and carbonated drinks are less hydrating than water. Caffeine, in higher amounts may act as a diuretic. Consuming four or more caffeinated drinks per day is considered “high” intake of caffeine. In larger quantities, caffeine can dehydrate you. Because low-carb diets shed water first, then pounds, your body needs more water to lose weight while in ketosis in order to burn and flush fat. You might think because soda contains water you are “balancing” caffeine’s dehydrating effects with the fluid in diet sodas, but studies show caffeinated drinks and those that are merely carbonated (even decaf drinks) are less hydrating than water. The fluid in diet soda is not handled by your body in the same way as water. If you hate water, try decaffeinated tea. 2. High sodium drinks can cause water retention. You might be able to get away with drinking diet soda all day with other types of weight-loss programs, but low carb diets are naturally diuretic. Large intake of sodium (found in sodas) can cause water retention which can make it appear your weight has stalled. 3. Diet soda can increase hunger and cause fat storage. Although caffeine is often touted as a mild appetite suppressant it a Continue reading >>

Can Caffeine Kick You Out Of Ketosis?

Can Caffeine Kick You Out Of Ketosis?

Low-carb dieters who consume very few carbohydrates often go into ketosis. Ketosis develops when you use up your glycogen stores and need an alternate source of energy. Your body forms ketone bodies as it breaks down fat to use for energy, and you excrete ketones in the urine. Low-carb dieter use ketone test strips to ensure that they're following the diet correctly and burning fat. Caffeine might disrupt glucose metabolism, which could affect ketosis, although only anecdotal evidence of this exists. Video of the Day Insulin resistance, the inability of cells to respond to and absorb glucose, can raise glucose levels and cause weight gain. Ketosis decreases insulin resistance by improving insulin sensitivity, meaning the ability of cells to absorb glucose. Insulin helps cells take glucose from the bloodstream to use for energy. Improving insulin sensitivity helps you lose weight. Caffeine might increase insulin resistance. Caffeine and Insulin Resistance Caffeine might increase insulin resistance, which might make losing weight more difficult and also increase your chances of developing type 2 diabetes, although this has not been clinically proven. A study conducted by researchers from Duke University Medical Center in the August 2004 issue of "Diabetes Care," published by the American Diabetes Association, discussed the effects of caffeine on blood glucose levels and insulin sensitivity. This study showed that 250 mg of caffeine did not change fasting glucose levels but did raise glucose levels after consumption of 75 g of glucose compared with placebo. Although caffeine might raise glucose levels after eating a meal high in carbohydrates, it's unclear that this effect occurs after a low-carbohydrate meal such as those eaten by low-carb dieters. It's also unclear wheth Continue reading >>

Does Caffeine Impact Ketosis On A Low-carb Diet?

Does Caffeine Impact Ketosis On A Low-carb Diet?

In an ideal world, there would be clear-cut criteria laid out in black and white about how to do a low-carb diet. While there are certain basics that apply to virtually every low-carb plan, there are also what I would describe as “gray areas” where it will really depend on the individual to figure out for themselves. One such issue is caffeine. If you have read Dr. Atkins’ New Diet Revolution, then you know the late great Dr. Robert C. Atkins addresses this subject a couple of times–but only in passing. Here are the two brief references I found in my mass paperback version of the book: Page 189–“Excessive caffeine has been shown to cause a hypoglycemic reaction, which will provoke cravings and cause you to overeat. Omitting caffeine may be a big sacrifice for you, but, in my experience, weight loss often starts up again as soon as people remove caffeine from their regimen.” Page 222–“Consume caffeine only in moderation.” Other than those two points, Dr. Atkins didn’t say much else about caffeine consumption. Obviously he felt there was enough of a negative metabolic response to caffeine intake for him to dissuade Atkins dieters to try to steer clear of it as much as possible. But what about the impact of caffeine on ketosis? Is there any and what guidelines can people following a low-carb diet use to gauge what amount of caffeine intake they can tolerate while still losing weight? These are some of the questions that were explored by one of my intelligent readers in the following e-mail: Hi Jimmy, I would like to clear something up with your help. I feel there needs to be a summary, possibly a FAQ, on caffeine. Here’s my question: What are the effects of caffeine, ESPECIALLY when one is in ketosis? When talking about caffeine, there are several h Continue reading >>

Ketosis & Ketone Test Strips

Ketosis & Ketone Test Strips

Discuss this article! By Doreen EVERYTHING YOU'VE EVER WANTED TO KNOW ABOUT KETOSIS ... 1. What are ketones? 2. How will ketosis help me to lose weight? 3. But, isn't ketosis dangerous? 4. How do the ketone test strips work, and where do I get them? 5. I'm following Induction strictly; why won't my strips turn purple? 6. Will I lose weight faster if the strips show dark purple all the time? 7. Does caffeine affect ketosis? 8. Will drinking alcohol affect ketosis? What are ketones? Ketones are a normal and efficient source of fuel and energy for the human body. They are produced by the liver from fatty acids, which result from the breakdown of body fat in response to the absence of glucose/sugar. In a ketogenic diet, such as Atkins ... or diets used for treating epilepsy in children, the tiny amounts of glucose required for some select functions can be met by consuming a minimum amount of carbs - or can be manufactured in the liver from PROTEIN. When your body is producing ketones, and using them for fuel, this is called "ketosis". How will ketosis help me to lose weight? Most reducing diets restrict calorie intake, so you lose weight but some of that is fat and some of it is lean muscle tissue as well. Less muscle means slowed metabolism, which makes losing weight more difficult and gaining it back all too easy. Ketosis will help you to lose FAT. Being in ketosis means that your body's primary source of energy is fat (in the form of ketones). When you consume adequate protein as well, there's no need for the body to break down its muscle tissue. Ketosis also tends to accelerate fat loss --- once the liver converts fat to ketones, it can't be converted back to fat, and so is excreted. But, isn't ketosis dangerous? Being in ketosis by following a low carbohydrate diet is Continue reading >>
