Perfect Keto Review - 17 Things You Need To Know

Perfect Keto Review - 17 Things You Need To Know

Perfect Keto claims to force your body into a state of ketosis or fat burning. But, before we go into that, this is what I’m asking: “Does Perfect Keto work for weight-loss?” Here’s the upside: Perfect Keto is an exogenous ketones supplement that’s easy to use and can be used with a Keto Diet. Here’s the downside: Some users don’t like the taste, which is a big deal for some. But, here’s the kicker. It gets better! So, let’s find out more about Perfect Keto and exogenous ketone supplements. What is Perfect Keto? Perfect Keto is a collection of dietary supplements developed by Dr. Anthony Gustin to enhance the effectiveness of a ketogenic approach. A ketogenic diet, or “Keto”, is credited with solving diseases and disorders that range from epilepsy to type II diabetes. Keto adherents will also tell you that it’s the easiest and quickest way to lose unwanted fat and attain mental clarity and athletic prowess once you leave your sugar addiction behind. [1] Once the body becomes fat-adapted, it burns ketones for fuel (instead of glucose), which means fewer insulin spikes and a calmer hormonal profile. Perfect Keto claims to support the transition to a fat-burning state and help keep your electrolytes balanced once you’re there. The Company Behind Perfect Keto The man behind Perfect Keto is Dr. Anthony Gustin, who makes mention of his status as a Doctor frequently in all of his online literature. Dr. Gustin’s doctorate is in chiropractic medicine. He also runs Equip Foods, a nutritional supplement company. Voted Best Chiropractor in the San Francisco Bay Area 2014 and 2015, he became a 360-degree health and fitness guru — training in functional medicine and working as a CrossFit coach, strength coach, and nutrition planner for hundreds of athlet Continue reading >>

Exogenous Ketones- Do They Deliver For Performance And Weight Loss?

Exogenous Ketones- Do They Deliver For Performance And Weight Loss?

Exogenous Ketones- Do They Deliver For Performance and Weight Loss? If you have been living under a rock and have not heard of the ketogenic diet yet, exogenous ketones are NOT those raspberry ketones for weight loss. We are talking about ketones as in the fuel derived from fat, during a high-fat diet such as the ketogenic diet. Why the ketogenic diet? While many still consider this diet controversial (because of the fat), it is not something new; rather it has been successfully used as an alternative treatment for epilepsy since the early 1900s. Today, however, the fat adapted state that the ketogenic diet brings on, is mainly used for rapid weight loss. As well as for reversing metabolic diseases such as type 2 diabetes and improving cognition and emotional health. Exogenous ketones is a new breakthrough supplement which primarily provides the power of ketones, without the need to follow the ketogenic diet so strictly. At least this is how it is marketed, but the question is, does it deliver? The Pros Since the research is still in the very early stages concerning exogenous ketones, much of their benefits are believed to be similar to the beneficial effects of the ketogenic diet. Here is the lowdown on the potential pros currently being researched: Appetite suppression (since ketones primes the body to burn its body fat for fuel) Less potential to cause gastrointestinal distress compared to MCT oil (an oil that the body easily converts into ketones) Potentially enables you to derive the benefits of a ketogenic diet while still eating carbohydrates, such as weight loss and increased endurance (users report it is possible as long as you keep the carbs low GI) Anti-carcinogenic (increased survival in mice with systemic cancer by 70%) Neuroprotection Clearly, the potentia Continue reading >>

Keto Os Review

Keto Os Review

Created by Prüvit, Keto OS, which stands for Ketone Operating System, is a “revolutionary drink mix based on a proprietary ketone energy technology. It delivers advanced macro nutritionals and promotes optimized cellular regeneration, energy and longevity.” [1] Also known as the keto diet, KETO OS is a line of supplements that promise to turbocharge your metabolism and send your body into ketosis without resorting to the draconian no-carb, all-fat diet. The History of Ketones Known for centuries, it wasn’t until a hundred years ago that ketones (Beta-hydroxybutyrate) were used to treat seizures in kids with epilepsy. A “neuroprotective effect” was produced, which calms the nervous system. Soon researchers were exploring an expanded use of ketones to help with mental, emotional and cognitive health, according to Prüvit spokesperson Andra “Dr. Andy” Campitelli , a naturopathic doctor. She says ketone use was expanded as a tool to enhance athletic performance. Ketones result when the body burns fat for fuel. [2] Prüvit on Better Business Bureau There are two Prüvit profiles on the Better Business Bureau site, one in Indiana and one in Texas. Both sell Prüvit products, but have no website link. The Texas profile has an F rating, mostly for lack of response to customer complaints about return issues. The Indiana profile has an A rating, but no reviews or complaints, and it’s only been open a year. Neither profile lists the CEO the same as the website. There is no phone contact on either the Prüvit website or the Texas BBB profile, only an “Ask a Question” form that goes via email. The Indiana profile does have a phone number: (812) 631-4282.

How To Use (and Not To Use) Exogenous Ketones For Weight Loss

How To Use (and Not To Use) Exogenous Ketones For Weight Loss

“How do I use ketones to help me lose weight?” Great question. It’s worth the few minutes to understand how exogenous ketones can help people lose weight on a ketogenic diet, and not just jump to the conclusion that ketones = weight loss. Breaking Down Ketone Weight Loss Misconceptions The most common misconception (perhaps due to excessive marketing claims) is that taking ketone supplements will induce immediate weight loss. The purpose of this article is to explain how to use ketones as a piece of the puzzle in your weight loss lifestyle. Remember exogenous ketones are supplements. Very effective at what they do, but none the less, should be supplementary to a low carb/ketogenic style of eating that is geared towards weight loss (if weight loss is the goal). Ketones don’t cause weight loss, they help cause ketosis. Ketosis is a metabolic state where your body is using fatty acids for its primary source of energy. Just because you are using fat does not necessarily mean you are going to be losing weight or have a decrease in body fat percentage over an extended period of time. I have been in deep nutritional ketosis (>3.0mmol/dL) and had an increase in body fat percentage. I’ve also been in deep nutritional ketosis and had a decrease in body fat percentage. It all depends on how much fat and protein you are eating, in addition to being below a carb threshold that will induce ketosis. Please don’t take this to mean starve yourself. It just means that the average male American has over 40,000 calories in stored body fat and can, therefore, afford to eat a lower calorie ketogenic diet, and still survive (and thrive!). Take home message: Exogenous ketones are a tool to get you into ketosis or to boost your energy levels while already in ketosis. If your motive Continue reading >>

Exogenous Ketones: Explained

Exogenous Ketones: Explained

WHAT ARE THEY? You may have read our previous article about a Ketogenic Diet explaining what ketosis is and how ketones are produced naturally inside the body. Well, this article focusses on Exogenous Ketones, ketones which are produced outside the body. Endogenous – Originates from a source internal to the body Exogenous – Originates from a source external to the body Ketones, aka ketone bodies, are a result of the body burning fat instead of glucose as its major fuel source. The body goes into a state of natural ketosis when carbohydrates are limited to no more than 20g per day. Exogenous ketones are lab-made supplements which provide an instant supply of ketones to the body (peaks at ~1-2 hours), without the prior depletion of carbohydrate reserves (Cox 2014, Pinckaers 2017). THE BASIC SCIENCE Ketones are a result of increased glycogen breakdown, gluconeogenesis (generation of glucose), lipolysis (the breakdown of fats), fatty acid oxidation and ketogenesis (Comstock 1990). When exogenous ketones are ingested, they undergo many biological processes with the end result of Acetyl-CoA molecules. Acetyl-CoA then enters the Krebs Cycle and generates a source of energy known as adenosine triphosphate (ATP), as can be seen in the image below. Acetoacetate (AcAc) and Beta-Hydroxybutyrate (BHB) are formed endogenously by the liver in response to low blood glucose and insulin levels (Cox 2014). BHB is the ketone used in most commercial supplements. There are two types of ketone supplements: Ketone Esters: Synthetically made compounds which link an alcohol to a ketone and is metabolised in the liver. These are unpleasant in taste and mostly used in research environments. Ketone Salts: Naturally derived compounds which mix ~1g sodium (most common), calcium or potassium with Continue reading >>

Beta Hydroxybutyrate

Beta Hydroxybutyrate

Summary Beta hydroxybutyrate (BHB) is the first ketone body produced in a fasting state. It is commonly produced by the body during periods without much food (glucose) in order to provide an alternative energy fuel source [1]. Although it is not technically a “ketone” (owing to the bonding structure), for the purposes of this post it is. Diets that are low in carbohydrates and high in fatty acids can either prompt the body to produce ketone bodies, such as beta hydroxybutyrate, or allow people to consume them exogenously (outside the body) instead. These exogenous ketone supplements have grown in popularity along with the ketogenic diet and media attention from popular icons such as Tim Ferriss [2] and Dave Asprey [3]. Although supplementation of beta hydroxybutyrate has been described as “jet fuel” [4] and undesirable, modern iterations of exogenous ketones are making it easier for anyone to utilize these ketone bodies for optimal brain performance. Also Known As Ketone bodies, Beta-hydroxybutyric acid, 3-hydroxybutyrate Editors’ Thoughts on Beta Hydroxybutyrate Making exogenous ketones palatable is one of the most exciting things for me right now. As I prepare to embark on an experiment doing cyclical ketosis with my girlfriend, exogenous ketone bodies like beta hydroxybutyrate will be incredibly important for kickstarting ketosis (for her especially). The addition of beta hydroxybutyrate will make the ketogenic process easier, though I’m not sure how much. Mansal Denton, Nootropedia Editor Benefits of Beta Hydroxybutyrate There are a host of benefits of beta hydroxybutyrate, but it is primarily known as a fuel source in the absence of glucose. Within 24 – 72 hours without food, the body no longer uses glucose as the main fuel support system, which is wh Continue reading >>

My Experience With Exogenous Ketones

My Experience With Exogenous Ketones

Last year I wrote a couple of posts on the nuances and complexities of ketosis, with an emphasis on nutritional ketosis (but some discussion of other states of ketosis—starvation ketosis and diabetic ketoacidosis, or DKA). To understand this post, you’ll want to at least be familiar with the ideas in those posts, which can be found here and here. In the second of these posts I discuss the Delta G implications of the body using ketones (specifically, beta-hydroxybutyrate, or BHB, and acetoacetate, or AcAc) for ATP generation, instead of glucose and free fatty acid (FFA). At the time I wrote that post I was particularly (read: personally) interested in the Delta G arbitrage. Stated simply, per unit of carbon, utilization of BHB offers more ATP for the same amount of oxygen consumption (as corollary, generation of the same amount of ATP requires less oxygen consumption, when compared to glucose or FFA). I also concluded that post by discussing the possibility of testing this (theoretical) idea in a real person, with the help of exogenous (i.e., synthetic) ketones. I have seen this effect in (unpublished) data in world class athletes not on a ketogenic diet who have supplemented with exogenous ketones (more on that, below). Case after case showed a small, but significant increase in sub-threshold performance (as an example, efforts longer than about 4 minutes all-out). So I decided to find out for myself if ketones could, indeed, offer up the same amount of usable energy with less oxygen consumption. Some housekeeping issues before getting into it. This is a self-experiment, not real “data”—“N of 1” stuff is suggestive, but it prevents the use of nifty little things likes error bars and p-values. Please don’t over interpret these results. My reason for shari Continue reading >>

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 >>

Keto Os Side Effects And Benefits: Is It Worth It?

Keto Os Side Effects And Benefits: Is It Worth It?

Keto OS or — as the company writes it — KETO//OS is an exogenous ketone supplement that promises better mood, strength, energy, sleep, focus, and fat loss. Here is a description of the product directly from the website: “KETO//OS® (Ketone Operating System) is a revolutionary drink mix based on a proprietary ketone energy technology. It delivers advanced macro nutritionals and promotes optimized cellular regeneration, energy and longevity.” With the subtle hints of science and the usage of unnecessarily complicated terminology, this supplement smells a lot like another fat loss supplement scam. Could KETO//OS’s advanced macro nutritional energy technology really improve mood, strength, energy, sleep, focus, and fat loss? Plot twist. Some — but not all — of Pruvit’s claims may be true. Unfortunately, there may be some downsides as well. A Quick Overview of Ketones, Ketosis, and Other Keto Terms Before we jump into the science and side effects of KETO//OS, we must develop a basic understanding of some not-so-common terms. Throughout this article, you will see the words ketosis, ketogenesis, ketones, ketone bodies, and exogenous ketones. They are all related, but also have some significant differences. Ketosis is when our body burns ketones for fuel, and these ketones are created via a process called ketogenesis. For the purposes of this article, ketones and ketone bodies are one in the same (to find out the differences between the two, check out our article on ketones). Ketone bodies are produced by the liver during periods of starvation or carbohydrate restriction. Exogenous ketones are ketone bodies that are not made endogenously (in the body). They are typically ingested in the form of ketone salts, which are the main active ingredients in Keto//OS prod Continue reading >>

The Keto Diet Podcast Ep. #059: Your Exogenous Ketone Questions Answered

The Keto Diet Podcast Ep. #059: Your Exogenous Ketone Questions Answered

Interview with Dr. Anthony Gustin, discussing all of your most asked questions about exogenous ketones: signs you need exogenous ketones, having carbs with ketones, exogenous ketone misinformation, fasting with exogenous ketones, and so much more. While on the tour, I received so many questions about exogenous ketones — who should use them, when to use them, how to use them, and most often: why and why not to use them. Because I can only speak from my experience and I’m not an expert on exogenous ketones, I decided it would be helpful to bring someone on the podcast who is! That’s where Dr. Anthony Gustin comes in — it’s not his first podcast rodeo, either. Last time he was on the podcast, we scratched the surface on Responsible Exogenous Ketone usage, but this time? We took it a bit further and tried to cover all the bases. Honestly, I learned so much and I’m thankful that Anthony was able to share his expertise. I hope you appreciate his message, as well as the ultimate takeaway: exogenous ketones aren’t a requirement and they’re not a replacement for eating whole foods. In today’s podcast, I chat with our guest Dr. Anthony Gustin, a board certified sports physician, functional medicine practitioner, and overall food and fitness skeptic about exogenous ketones. This episode is all about understanding the proper uses for exogenous ketones, who should and shouldn’t use exogenous ketones, plus timing, fasting, side effects, misinformati Continue reading >>

Perfect Keto Review

Perfect Keto Review

Disclaimer: Perfect Keto products have been provided to me for the purpose of this review by Perfect Keto as free samples. This has not influenced my review and the opinions expressed in this post are my own. I am not affiliated with Perfect Keto. Supplements with exogenous ketones have become increasingly popular within the keto community. While exogenous ketones show promising results in certain areas, there has been lot of misinformation that needs clarification. Sadly, some exogenous ketone supplements are sold via what is known as multi-level marketing (MLM). What bothers me with MLM strategies is that they employ an ever growing army of unqualified distributors that go to great lengths to sell exogenous ketones as a "miraculous weight loss product." Want to know more? Check out the comment section for my replies. But not all companies follow a MLM strategy and Perfect Keto, who make exogenous ketone supplements and MCT oil powder, is one of them. Are they worth the price tag? I listed all potential benefits and side effects - it's up to you to decide. What is Perfect Keto made of? As opposed to endogenous ketones that are produced by the body, exogenous ketones are supplemented. There are two types of exogenous ketones: synthetically made ketone esters that are primarily used in research commercially available exogenous ketone supplements, such as Perfect Keto, made with naturally derived ketone salts Each pack of Perfect Keto is made with beta hydroxybutyrate (BHB), calcium, magnesium, natural flavours, citric acid and stevia. How does it work? BHB raises blood ketone levels after ingestion, providing the body with extra energy in a similar (but not the same) way endogenous ketones do (see sections below for more info). How does Perfect Keto taste? They come in t Continue reading >>

The Beginner’s Guide To Exogenous Ketones

The Beginner’s Guide To Exogenous Ketones

Have you been wondering what exogenous ketones are? If so, you’re not the only one. The keto-dieting world has been buzzing with information about developments on exogenous ketones for awhile now, with many brands producing exogenous ketones that are used by Keto lifestylers around the world. But the majority of Keto dieters don’t completely understand what exogenous ketones are or how they can benefit their diet (or dieting options). In this post, we’ll provide you with easy to read information about exogenous ketones. With this knowledge, you’ll be able to utilize exogenous ketones in your diet, and teach others about their value. Let’s start with the label! The Definition of Exogenous Ketones Two words: exogenous and ketones. The word exogenous describes something that is developed from external factors; something outside of the usual production. So in terms of ketones, this means that exogenous ketones are synthetic: created outside of your body by scientists and then ingested for accelerated ketosis. We assume that you already know what ketones are, but just in case, we’ll give you a brief description of this term as well. Ketones, are organic compounds produced by in your body when your system experiences starvation, or when you restrict carbohydrates and increase fats, which inhibits a starvation-like state that produces ketone bodies. These ketones are an ideal fuel source for your body and your brain. Studies have suggested that when your body is in a ketogenic state, it utilizes oxygen more efficiently in the generation of energy. In short, ketones are secret weapons for anyone looking to take their body’s fueling system to the next level! To restate the point: Exogenous Ketones are ketone supplements. They’re created outside of your body and i Continue reading >>

Exogenous Ketones Review And Benefits

Exogenous Ketones Review And Benefits

Before I give you my exogenous ketones review, let’s back it up for a second..What exactly are the best exogenous ketones on the market and why does everyone keep talking about it? To put it in layman’s terms, they are simply “synthetic” ketones that are consumed in order for your body to help adapt into a state of ketosis. What are ketones? An alternative fuel source to glucose. They are produced when the body burns fat for energy. It’s also produced when you have low body fat or there isn’t enough insulin to help your body use sugar for energy. Ketones are the preferred source of energy for our body. It is used much more efficiently and has been known to produce a wide range of health benefits. There are two types of ketones that can be produced. 1. “endogenous” ketones = ketones produced from INSIDE your body. This is the natural process by which your body produces ketones by restricting carbohydrates and instead burning fat as fuel. 2. “exogenous” ketones = external ketone bodies that are consumed as a supplement. So instead of ketones being produced in the liver (endogenous ketones), ketones that are simply taken as a supplement are considered exogenous ketones. You’re basically providing your body with an automatic supply of ketones to utilize EVEN IF you are NOT in ketosis prior to ingesting it. This is huge for the keto dieters out there because this means we can eat decently carb-heavy meals while still maintaining a decent state of ketosis… …thus, still providing the benefits of — sustained energy, decreased anxiety, boost in mood and concentration, etc.. The main problem for beginners going on the ketogenic diet is sticking it out long enough to actually start getting the benefits. People give up too soon, right before they hit gol Continue reading >>

Exogenous Ketones: To Ketone Or Not To Ketone

Exogenous Ketones: To Ketone Or Not To Ketone

My thoughts on Exogenous Ketones After being contacted (following the Youtube Q&A) by several folks – both members of Ketogains and Internet strangers, I felt compelled to write as fair and even-handed a write-up on exogenous ketone supplementation as I feel can be mustered. I condition my response by saying this – I want to deal only in evidence and hypotheses grounded in biochemistry. I admit up front that this will probably become something of a treatise on what constitutes a well-formulated ketogenic diet. I don’t have the time (or the energy) to put together a document that covers all facets of the use of exogenous ketones in sufficient depth, so what I want to do is to address the folks that I see asking me about them most often – those who have excess body fat, and are looking to lose weight. They have been told about the potential benefits to fat loss via exogenous ketones, and they want to know if the hype is real. Those of you who know me (or read my previous post here) know that I like to respond with “it depends.” So…when the question is raised, “Should I supplement with exogenous ketones?” what do you think my answer will be? Probably not! (HA, I tricked you!)…but let’s explore why. As I’m sure this is going to be hotly debated enough (as the topic is raging in numerous ketogenic groups) there isn’t any value in dealing with speculation that doesn’t have a basis in science, nor in anecdotes. The challenge in dealing with exogenous ketone supplementation is two-fold: One side of the debate has a product to sell. Anytime someone’s livelihood is tied to your purchase of their product, bias and subjective interpretation of the evidence should be considered. The evidence (either for or against) their supplemental use by average schl Continue reading >>

How To Use Exogenous Ketones

How To Use Exogenous Ketones

Exogenous Ketones were introduced in 2014, about the same time as I was recovering from having my daughter, and therefore very concerned about weight loss. But let’s back up for a bit, because if you’re here reading about Exogenous Ketones, and how to drink ketones for weight loss, let’s start at the beginning so you have a firm foundation to build if you do decided to take a ketone supplement for weight loss. First of all, Exogenous Ketones (we’ll get to exactly what those are in just a sec…hang in there) were introduced as the Ketogenic Diet started gaining popularity among the health and fitness community, as well as with the scientific community. Why? Well, it’s all about health. For so long, doctors and researchers have preached the benefits of a low-fat diet to prevent and correct all sort of things like heart disease, high cholesterol, obesity, etc. But….they may have been wrong. I am not a doctor, and do not have a medical degree, but I’ve done my homework, and I’ve lived (and am currently living) a ketogenic lifestyle. So I’ve done this, I’ve read loads and loads about it, and I’ve even been able to help many of my friends use the things I’ve learned to lead healthier lives. But, as with anything concerning your health, please make sure you have a discussion with your doctor before making a drastic change. Related: I lost 23 pounds in 60 days of Keto. Here’s how. Ok, legal stuff over, here’s what a Ketogenic Diet is: A Ketogenic Diet, also know as the Keto Diet, is a very high fat, very low carb, moderate protein diet that is very popular because it can cause you to lose body fat very fast, and study after study after study has linked Keto with benefits against cancer, diabetes, Alzheimer’s, epilepsy, and more. Eating Ketogenical Continue reading >>
