Silicon Valley's Favorite Diet Has Techies Eating Lots Of Fat

Silicon Valley's Favorite Diet Has Techies Eating Lots Of Fat

Geoffrey Woo, left, is one of Silicon Valley's biohackers — those who experiment with diet and medical devices in a DIY approach to biology.Melia Robinson/Business Insider Geoffrey Woo likes to start the day with a plate of eggs, cheese, and avocado. It might not sound as if Woo — cofounder and CEO of "cognitive enhancement" supplements startup Nootrobox — is dieting. But he subscribes to an increasingly popular diet — the ketosis or "keto" diet — that he hopes will help him live longer and better. It has especially gained traction among Silicon Valley's biohackers, who often experiment with diet and medical devices in a DIY approach to biology. The high-fat, low-carb diet turns the body into a fat-burning machine. When you turn off access to glucose, a primary fuel source derived from eating carbohydrates, the body taps into its own fat stores for energy. Here's why health nuts, from Silicon Valley to fashion runways, are saying yes to fat. The keto diet has been called the "holy grail of good health and weight loss" by some doctors and bloggers. Melia Robinson/Business Insider Sources: Nootrobox, GreenMedInfo.com On the flip side, it's a nutritionist's nightmare, according to Scientific American. The keto diet completely reorganizes the building blocks of the food pyramid as outlined by the USDA. A strict keto diet cuts back carb consumption to 20 or 30 grams a day, which is about the number of carbohydrates in one small apple. Source: Time On the keto plan, it's all about healthy fats. "You'd want healthy fats to account for about 80% of your calories, and protein around 20%," Dr. Eric Westman, director of the Lifestyle Medicine Clinic at Duke University, told Time. By comparison, Americans, on average, get about 50% of their calories from carbs, 15% from p Continue reading >>

A New Toy Measuring Blood Ketones

A New Toy Measuring Blood Ketones

I just got a new toy: a device for measuring blood ketones. This is a far more exact and reliable measurement than testing for urine ketones using cheap dipsticks. Ketosis is of course the state the body is in when eating very low carb. Ketones, made from fat, will then fuel the brain instead of glucose. So who needs one of these gadgets? Perhaps nobody. Obviously it’s easy to eat LCHF without it. This is for curious nerds (like me) and for those who want definite proof that they are eating so little carbs that insulin levels are low and fat burning is maximized. A ketone level somewhere between 1.5 – 3 is said to be an optimal level for maximizing weight loss. It means that insulin levels are very low. As you can see my first measurement was 0.2, after a caesar sallad dinner. I’m not surprised as I’ve probably eaten at least 50 grams of carbs a day lately. I will try it out fasting in the mornings during the coming days. Perhaps I’ll try being really strict with the carbs for a while to see what happens. Have you tried one of these or are you interested in doing it? Continue reading >>

Ketone Testing

Ketone Testing

Tweet Ketone testing is a key part of type 1 diabetes management as it helps to prevent a dangerous short term complication, ketoacidosis, from occurring. If you have type 1 diabetes, it is recommended that you have ketone testing supplies on your prescription. Ketone testing may also be useful in people with other types of diabetes that are dependent upon insulin. Why test for ketones? Ketones are produced by the body as an alternative source of energy to sugar. The body produces ketones by breaking down fats, this process is known as ketosis. Ketones may be produced as part of weight loss, however, it’s important for people with diabetes on insulin to note that ketones can be produced when the body has insufficient insulin. When the body has too little insulin, it means that cells of the body cannot take in enough sugar from the blood. To compensate for this, the body will start to break down fat to provide ketones. However, if a high level of ketones is produced, this can cause the blood to become acidic which can lead to illness and even potential danger to organs if not treated in time. This state is referred to as diabetic ketoacidosis. Where can I get ketone testing kits and sensors? The most accurate way of testing for ketones is to use a meter that measures blood ketone levels. The following blood glucose meters are able to test blood ketone levels in addition to blood glucose levels: Abbott - FreeStyle Optium Neo Menarini - GlucoMen LX Plus If you take insulin, you should be able to get these prescribed by your GP. You can also test urine for ketone levels, however, urine ketone testing is not as accurate as blood ketone testing as the levels of ketones in the urine will usually only reflect a level of up to a few hours previously. When to test for ketones? Continue reading >>

Measuring Ketosis: What Are Keto Sticks And Keto Strips?

Measuring Ketosis: What Are Keto Sticks And Keto Strips?

Ketosis is a metabolic state where the liver breaks down fat to produce ketones. Ketones, on a ketogenic diet, are the primary fuel source for the body. If you’re new to the ketogenic diet and you still have questions, consider reading our Comprehensive Beginner’s Guide to Keto > There are three main ways to measure the ketones in your body, all of which have their advantages and disadvantages. The most common ways to measure are: Blood Ketone Meter. Very accurate but the strips are extremely expensive. Breath Ketone Meters. More accurate than the urine strips, but can sometimes vary in accuracy. Cheaper than blood strips in the long-run. Urine Stricks. This will answer the question “Am I in ketosis?” but will not provide an accurate measure of blood ketones. Scroll down to read a more in-depth analysis of each, and what we recommend for you. Measuring Ketones with Urine Sticks Urine sticks will always be the cheapest and easiest way to measure ketosis. For beginners, this should cover everything you need – there is no point in getting more complex blood strips so early on when you are still trying to understand the nuances of a ketogenic diet. Ultimately, keto sticks are very easy to use – you hold the sticks in your urine stream for a few seconds, and within 10-15 seconds you should notice a color change in the strip (if you are in ketosis). The color of the stick typically is measured in red: light pink being low in ketone production and dark purple being high in ketone production. While keto sticks can be ideal for a general answer to the question “Am I in ketosis?”, they aren’t precise with their accuracy. They measure the acetoacetate in your urine, which is an unused ketone by the body. As you get deeper into ketosis and your body adapts, your b Continue reading >>

The Best Ketone Meters To Monitor Ketosis – Christmas 2017

The Best Ketone Meters To Monitor Ketosis – Christmas 2017

The goal of a high-fat, low-carb diet is to get into a state called Ketosis where the body burns fat as fuel rather than using glucose as its source of energy. Types of Ketone Meters There are several types of ketone meters available that monitor ketosis in vastly different ways, some more accurate than others and some more convenient others. We’ll discuss 3 types of Ketone Meters available starting with the best on the market today in 2017. Ketonix Breath Ketone Analyzer The Ketonix breath analyser doesn’t use any blood glucose test or test strip, it works by analysing acetone on your breath that your body produces when you’re in a state of ketosis. The Ketonix is slightly less accurate as blood ketone and glucose meters are per test. But they are more convenient With the Ketonix, you can test yourself an unlimited amount of times, hourly if you like. Which is ideal if you want to see how various foods effect ketosis after you’ve eaten them or even the effects exercise has. The Ketonix is affordable when you take into account the price of test strips for blood monitors. (Many companies give away cheap versions of blood monitors but make their money on testing strips). The Ketonix has no test strips and requires no further outlay. Ketonix also comes with software that will keep a log and also calibrates the device to the optimal settings for your goals. If you’re trying to monitor ketones under conditions such as athletic performance, weight loss, diabetes, alzheimer’s or epilepsy. The Ketonix adjusts its settings to test whether you’re in the ideal range for that condition. The Ketonix Breath Ketone Analyzer is a one-off payment you can read more & check them out here. Blood Ketone Meter One of the best & most precise ways of monitoring ketosis is with a Continue reading >>

How To Measure Ketones And Optimize Ketogenic Diets

How To Measure Ketones And Optimize Ketogenic Diets

The problem with diets is that we think that one diet should be good for everyone. But research and N=1 experiments show that’s not the case. Learn about measuring ketones and ketosis to understand how your low carb or high fat diet is really affecting you. If there is one area of our bodies that is debated to extremes, with literally hundreds of differing strong opinions on it, it’s nutrition. For many, beliefs about nutrition and diet are tribal. We put ourselves in different camps and we war agains the other camps. Whether it be paleo, low fat, low carb, Atkins, high fat, low protein, vegan, raw vegan and so on. It’s exactly this sort of area where I see data as essential. Without data we have no hope of cutting through the maze of opinions to get to what really works. Part of the problem with nutrition and diets is that we tend to think that one diet should be good for everyone. But increasingly, research and N=1 experiments, are showing that that isn’t the case. And this is exactly why you should pay attention to today’s show. Today, we’re looking at what has relatively recently become the fastest growing nutrition or diet trend. The high fat diet. Also known in different guises as the ketogenic diet, or the low carb diet. And specifically how this can affect our different individual biochemistries, how we can measure “Ketosis” and other biomarkers to understand how our specific biology is reacting to it… and allowing us to troubleshoot and course correct when it isn’t getting the desired results we’re looking for from it. Today’s guest is Jimmy Moore. In 2004, Jimmy, at 32 years, weighed 410 pounds. Since then he has transformed his own biology, shedding all that additional weight with low carb and ketogenic diets. He has also interviewed n Continue reading >>

3 Best Ways To Measure Ketones For Your Ketogenic Diet (review & Buyers Guide)

3 Best Ways To Measure Ketones For Your Ketogenic Diet (review & Buyers Guide)

How do you get accurate readings of ketones? Which methods actually work? These are common questions I going to help you with in this article. Anyone interested in using the latest nutritional research to improve their health has likely heard of a ketogenic diet. Ketogenic diets are a simple way to get your metabolism to prioritize the consumption of fatty acids, also known as ketones, when at rest or exercising. While there is a wide body of research that confirms the benefits of this type of nutritional plan, for the average user at home – one big question remains. How can you measure ketone levels to ensure your body is reaching a perfect state of ketosis? Without an accurate method of ketosis measurement, you will never achieve an optimized LCHF or ketogenic diet. However, it has not always been easy to measure your level of ketosis at home. At least this concern is now a thing of the past, because there are many ways to measure ketone levels easily and accurately in the comfort of your own home. Find out the very best method to test your level of nutritional ketosis that strikes the perfect balance of ease, price and quality. Before getting too deep into the different methods for measuring ketosis, it is important to first look at exactly why measuring them is so important and to clarify some of the more complex scientific terms. Ketone Testing Terminology If you have decided to try a ketogenic diet to achieve nutritional ketosis, then finding an accurate way to measure your ketone levels is important. You need to be able to maintain yourself in the optimal zone where fat is used as energy rather than glucose. Too little ketone and you will not see any positive effects. But higher levels give no real benefit and could indicate a serious problem with your diet. Li Continue reading >>

How The High-fat Keto Diet Became A Weight-loss Trend

How The High-fat Keto Diet Became A Weight-loss Trend

Developed for epileptics, the high fat, low carb approach to eating known as "keto" has become a popular weight-loss regimen. Corey Mintz finds out why devotees are very satisfied and experts a little skeptical Dan McKinnon starts his day with a coffee, like anybody else. Except that he puts butter in it. And MCT oil, a supplement high in a unique type of saturated fatty acid. If there's time for breakfast, the 34-year-old Toronto musician and arts administrator will scramble some eggs with cheese and wolf it down with three slices of bacon, two sausages and an avocado. When he's in a hurry, he'll stop at McDonald's for a sausage and egg sandwich – minus the bread. A typical lunch is a burger with cheese and guacamole. McKinnon will wrap the burger in lettuce instead of a bun, but since he's trying to eat a three-to-one ratio of fat to protein, he'll load it with as much of his favourite condiment as possible. "I live and die by Sriracha mayo," he says. Since January, McKinnon has lost 25 pounds. He credits the ketogenic diet, a low-carbohydrate diet designed to fuel the body with fat instead of glucose. For anyone who doesn't read diet magazines or follow #lowcarb, #holdthebun or #weightloss on Instagram or Twitter, it's an ultralow-carb, no sugar, no fruit, no beans weight-loss regimen. It's also very popular. The Keto Diet by Leanne Vogel is currently the top-selling book in Amazon Canada's diet and weight-loss category, and a slew of celebrities, including NBA superstar LeBron James, are rumoured to be acolytes. Developed in the 1920s to treat epilepsy, the diet was generally abandoned after the 1938 discovery that the drug diphenylhydantoin could be used to control seizures. Then, in the early 1990s, Hollywood director Jim Abrahams (best known for movies with exc Continue reading >>

Do You Want To Be A Fat-burning Machine? Become Ketogenic!

Do You Want To Be A Fat-burning Machine? Become Ketogenic!

If you want to become a lean, mean, fat-burning machine, the goal is to achieve a ketogenic state. When you’re in a ketogenic state, you’re producing ketones, an alternative fuel for the body created when glucose is in short supply. Ketones are made in the liver from the breakdown of fats. Most people never get down to burning fat because the Standard American Diet (SAD) is heavy in carbohydrates (a diet high in carbs means you store more fat and cannot readily access that fat for fuel). So they end up only burning carbs, not fat. When you eliminate high carbohydrate foods by implementing a ketogenic diet (for example, Paleo and Primal foods), your body starts to use the glucose stores in your muscles. When those glucose stores run low, fat released from your fat cells travel through the blood to reach the liver, where they are processed into ketone bodies for your body to use as fuel. The ketone units then circulate back into the blood stream and are picked up by the muscle and other tissues to fuel your body’s metabolism. You literally become a fat-burning machine. Most people have heard of ketones and ketosis because of the Atkins Diet, a diet especially popular in the 1990’s that allowed dieters to eat all the protein and fat they wanted as long as they stayed away from carbs. Low carb diets are still all the rage today. The first problem with a diet like Atkins is there is no focus on quality of food. There’s no distinction between a USDA Prime piece of antibiotic/hormone-laden steak and a naturally raised, grass-fed steak. No encouragement to choose organic produce over the kind you get all wrapped up in cellophane. Even if you don’t have a degree in nutrition, warning signals should sound in your head if any diet tells you it’s better to eat artific Continue reading >>

Precision Xtra Vs. Novamax Plus: Ketone Meter Evaluation

Precision Xtra Vs. Novamax Plus: Ketone Meter Evaluation

With the rise in interest in the n=1 experiment I’ve been blogging about since May 2012 (read my latest updates about it here, here, here and here), so many of you have begun testing your own blood ketones to see how well you are doing in pursuit of reaching that glorious state of “nutritional ketosis.” Attaining blood ketone levels of 0.5-3.0 millimolar is the optimal level for producing an appropriate level of beta-hydroxybutyrate to commence fat-burning and to serve as an excellent alternative fuel source for your brain and body for optimal performance according to what Dr. Stephen Phinney and Dr. Jeff Volek outline so beautifully in their outstanding MUST-HAVE 2012 book The Art & Science Of Low Carbohydrate Performance. If you haven’t already picked up your own copy of this book, then I cannot recommend it highly enough to you as an invaluable resource in your pursuit of living an optimally healthy low-carb lifestyle. As people have been shopping around for their own blood ketone meter, I’ve been getting a lot of e-mails from readers who have asked me for my recommendation between which of the two major ketone meters they should get to test their blood levels. Is there any difference between the Precision Xtra and NovaMax Plus blood ketone meters? I’ve personally tried both of these meters and have been using the Precision Xtra results to document my n=1 experiment. Let’s take a closer look at the PROS and CONS of each: **Precision Xtra Blood Ketone Meter** PROS: – Accurate and clear blood ketone measuring – Sturdy and strong test strips – More precise than urine ketone testing CONS: – Requires more blood than glucose testing – Test strips can be quite expensive – Not available for purchase in stores **NovaMax Plus Blood Ketone Meter** PROS Continue reading >>

How To Know If You’re In Ketosis: A Guide To Testing Ketone Levels

How To Know If You’re In Ketosis: A Guide To Testing Ketone Levels

Ketosis can be a powerful way to use your metabolism for fat loss, mental output, physical performance as well as many other health benefits. But how do you know if you’re actually in ketosis? As the old adage goes “test, don’t guess” when it comes to your health. In this guide, we’ll show exactly how to test your ketone levels to know if you’re in ketosis so you can make sure you’re getting all of the benefits that ketosis has to offer. There are three primary forms of ketones in your body, acetone, acetoacetate, and beta-hydroxybutryate. Each of these compounds do different things in the metabolism of ketosis and can be tested individually with differing techniques. Not all measurement is created equally, however, and some can be better than others for different purposes or times. The three different ketone bodies can be measured when they spill over into three different areas of your body: your breath, urine or blood. The good news is that all of these ketone level measurements can be done at home, by yourself. You don’t have to go to any lab or use any fancy high tech equipment. Tracking diligently, at least when you’re getting used to ketosis based diets, is important so you know how much you react to different variables like exercise, type and amount of food, and amounts of exogenous ketone supplements. Also, the optimal level of ketones for specific goals can vary per person. Knowing the amount where you thrive in the goal you want to achieve (and consistently checking if you’re hitting that amount) is the fastest way to reach your goals. Testing levels of ketones with urine strips (acetoacetate) One of the ketone bodies, acetoacetate, can be measured directly in the urine if they are in excessive levels. The way metabolic substrates get into Continue reading >>

How To Get Your Body Into Ketosis: 6 Simple Tips

How To Get Your Body Into Ketosis: 6 Simple Tips

If you’re looking to burn fat off your body fast, then you need your body to get into ketosis. This is the basis behind the ketogenic diet. Most of us have bodies that are sugar burners. This isn’t a bad thing. Most of our diets lead to our body wanting to burn sugars first anyway. That’s the problem, though, our diets. A lot of the foods we eat on a daily basis are going to convert into glucose when they are processed by our bodies. This leads to our bodies looking at the glucose as its main source of energy instead of fat. When your body is using sugar for energy, it’s burning that instead of any fat you may be wanting to get rid of. If you can get your body into ketosis, it will become a fat burner instead of a sugar burner. This means that your body will look to burn fat for energy instead of something else. You will then begin to start shedding fat off your body and you’ll begin seeing the pound come off. Getting into ketosis isn’t a very easy task. There is a process that you need to go through. Your body will be making a major change. You’ve probably been a sugar burner your entire life so changing into ketosis will be a giant leap. Tips to Get into Ketosis Below are going to tips on how to get your body into ketosis. They are proven tips so if you follow them, you should be a fat burner in no time. If you’re looking for more guidelines on how to change your body, look at this 28-day challenge that is guaranteed to help you drop fat and make your body a fat-burning machine. Lower Carb Intake One of the first things you need to do if you want to get into ketosis is to bring your carb intake way down. Not just a little bit, you need to have a significant drop in the amount of carbs you eat daily. This is by far the most important tip when it comes t Continue reading >>

How To Get A Free Blood Ketone Meter When Ketostix Fail

How To Get A Free Blood Ketone Meter When Ketostix Fail

When I initially started a ketogenic diet, I would use the urine test strips to monitor for ketones, which would tell me if I was in ketosis or not. I wish someone had told me about this free Blood Ketone Meter! However, I later found that my readings started to show nothing even though I had been eating a high fat, low carb diet. I wondered… what on earth was wrong? Why do Ketostix Stop Working? After doing some research, I found that once my body started to become accustom to a high fat diet and began to utilise the ketones for energy, the free ketones in my urine either did not exist or where not as strong. Ketostix work mainly off the concentration of ketones in your urine. This makes the long-term use of Ketostix useless, as they will eventually start to read blank. Ketostix start at a yellow colour (which means you are not in Ketosis) all the way up to a dark purple (which means you’re in fairly heavy ketosis). Click on the Image Below to get Ketostix in Australia The solution? Blood Ketone Meter! My girlfriend Adele loves to source out bargains at different chemists. As I came along to a few of these bargain hunting trips, I began to notice that I could use a device that is usually suitable for Diabetics called a Glucose Meter to monitor my ketones. Diabetics need to monitor their ketone levels as to avoid Ketone Acidosis (which can be very harmful). They need to be very precise due to the nature of health risks that ketosis can pose to diabetics. I wondered up to the counter to check the price of the device that also could check for Ketones. BAM! $70. I was not going to buy one from a chemist. You would have to be crazy! Later that night I started researching these devices on eBay. Low and behold, I stumbled across this device for $29. What I did not notice Continue reading >>
