Checking your ketone level is one way to know if you’re in ketosis. This metabolic state usually kicks in after three or four days of restricting your carbohydrate intake or going through periods of intermittent fasting. You don’t have to visit a doctor to measure your level. Pick up a ketone urine test from a nearby drug store, or use a blood sugar meter that’s capable of measuring ketones.
But not everyone’s a fan. “For most people, going keto means jumping on the diet of the moment bandwagon,” says Jackie Newgent, RDN, a culinary nutritionist in New York City and the author of The All-Natural Diabetes Cookbook. “For most, it’s a fad diet that will offer temporary results.” That runs counter to Newgent’s usual advice to find an eating plan you can follow for a lifetime. She also worries that reducing carbs as much as the original keto diet calls for will cut out nutrient-rich foods, like whole grains, certain veggies, and fruits.
O n e Y e a r : Thankful for the Gospel and it’s power to transform all areas of life. Only God’s grace allows me to look back one year ago (almost to the day) to reflect on how far He’s actually brought me and my family. Lots of “negative” circumstances took place over the course of the last year, but the perspective of the guy on the left is VASTLY different from the guy on the right. I truly believe there are no negative circumstances in this life, only misunderstandings of what’s actually good (dare I say, “best”) for us. Keep pressing on, keep pursuing, keep searching for the only One worth anchoring your hope to. | #wonthedoit #godisgoodallthetime #stewardshipoflife #identity #hope #fattofitjourney #50lbsandcounting #Keto
Atkins Nutritionals filed chapter 11 bankruptcy in 2005, a year after the doctor died after falling on an icy New York City sidewalk. Still, Atkins had a long-lasting impact on the dietary landscape in America. “Sugar free” and “low carb” labels never left the snack aisle. People still fell back on the idea that to lose weight, one simply had to cut carbs. But all the while, obesity rates climbed from 30 percent up to 39 percent of the country, priming the stage for another diet “revolution.”
Curiously, this study was funded by the Nutrition Science Initiative (NuSI), a group with the aim of producing “conclusive results in the next decade” in a sometimes confusing nutritional landscape. They claim our nutritional guidelines are “based on inconclusive science,” and though their website doesn’t directly indicate any bias, their research so far focuses on the effects of carbohydrates on obesity. This was the second published study that received funding from the institute. In the first study, published in the American Journal of Clinical Nutrition in 2016, researchers hypothesized that a low-carbohydrate diet increased energy expenditure. Results said otherwise:
“Given that there is no known detriment to consumption of a high-carbohydrate diet (other than body weight gain due to water retention) and some research reports a benefit, it is recommended that all athletes consume a high-carbohydrate training diet, i.e., at least 60-70% of energy as carbohydrate (7-10 g/kg), and increase this to 65-85% for the few days before competition. Use of a carbohydrate supplement before and during exercise will likely improve performance of intermittent, high-intensity sprints.”
Is it recommended to calculate our macros using the method suggested in the article to calculate yourself or by using the linked calculator? I get two different sets of numbers and am not sure which might be the better version. The main difference is amount of caloris and amount of protein to consume. The calculator gives me about 300 less calories, about the same amount of fat and carbs, but about 40 less protein than when I calculate myself.
The ketogenic diet: The ketogenic diet could affect cancer by a similar mechanism to calorie restriction and fasting. Of the 29 animal studies that have examined ketogenic diet and cancer, 72% of them have demonstrated an anti tumor effect. There have been a small number of case studies of the safety and efficacy of the ketogenic diet in humans. The results have been largely positive, for example following a ketogenic diet helped to stabilise tumour growth and alter tumor metabolism96 ,97 ,98. There is an absence of fully randomised clinical trials in humans, but 24 case studies have been published; one recent appraisal of the case study data said that “ a probabilistic argument shows that the available data strengthen the belief in the anti-tumor effect hypothesis (of the ketogenic diet) at least for some individuals"99.
Carbohydrates are your body's favorite fuel source; it breaks them down into glucose. Without a steady intake of carbohydrates, your body turns to using protein for fuel. But if you also are limiting how much protein you eat, your body is forced to burn stored fat as its primary source of fuel. That can result in weight loss, and ketones are a byproduct of burning fat.
For some, ketosis can cause more negative than positive side effects. Dorena Rode, a 52-year-old author, and speaker from Occidental, California, tried the diet for a month and experienced heart palpitations and dizziness. Unlike Drew, Rode says her cholesterol increased from 192 to 250 mg/dL after she introduced more fat into her diet. (Less than 200 mg/dL is considered desirable, while anything over 240 mg/dL is considered high.)
Thanks for the very informative article. This was the push I needed to at least try it. Starting next weekend, my partner and I will be trying keto for 30 days. I’m all for small changes, in theory, but what I sometimes discover is that sweeping changes can have their place, too, if they produce positive results. Often, what will work for me is trying a big change, and even if I then throw out 80% of it, at least the remaining 20% sticks. By contrast, any backsliding from a small change can often mean just throwing it out entirely.
“Keto is not easy to maintain, it’s not a palatable diet,” says Andrea Giancoli, a dietician and nutrition consultant in California. Getting 80-90 percent of your calories from fat—which is what’s generally required for keto—is actually difficult. It involves eating a lot of rich, heavy foods with little variety—think fatty meats and gravy on cauliflower. You’re only allowed 10 to 15 grams of carbohydrates per day, and though many dieters stretch that to more like 20 or 30 grams that’s still only about one banana. A single apple could also get you past that limit depending on its size (though the fiber in an apple means that many dieters don't count those carbs towards their daily limit) and a couple slices of bread likely fulfill the requirement as well.
Staying in Ketosis long-term: Chronic Ketosis can cause fatigue, muscle soreness, insomnia and nausea. "Unless you have a medical condition that requires you to stay in Ketosis for long-term, you shouldn't stay in that state for a prolonged period without any carb ups," Mavridis suggests. And if you're a beginner, "it’s recommended that you go through the fat-adaptation phase so that your body becomes accustomed to burning both glucose and fat for fuel," says the nutritionist.
I have lost 5lbs so far, but what I have gained is beyond measure. I have been reading, learning and listening to so many theories that Jen has led me to. I was mad as I found out more and more about what I thought I knew about diets and was completely wrong and causing damage to my body. I was nervous to try new ways of eating, but now I’m happy to be learning and changing. I am still learning better ways to exercise and trying to pay attention to how food makes me feel. The accountability and motivation from others has been wonderful! Dana Z
In order to obtain the most comparable measures, it is useful to measure blood ketones at the same time each day. Measuring immediately on waking means that there are fewer potential variables that could alter the measurement, such as exercise, or different food intake. However, it can also be useful to check ketone levels around 60-90 minutes after an intervention such after eating a fat rich meal or consuming exogenous ketones.
Blood tests often report the level of total cholesterol (HDL + LDL) as well as the levels of each type independently. It is possible that the relative abundance (ratio) of HDL: LDL is more important to predict the occurrence of cardiovascular disease that the total cholesterol level109. Whilst the ketogenic diet can cause an increase in total cholesterol, the ratio of healthy HDL : less healthy LDL generally increases (i.e more HDL)110 whilst following a ketogenic diet. In contrast, whilst total cholesterol tends to be lower whilst following a low fat diet, the ratio of HDL:LDL tends to be lower (i.e more LDL)21.
Ketone urine-testing strips, also called Ketostix or just ketone sticks ... are small plastic strips that have a little absorptive pad on the end. This contains a special chemical that will change colour in the presence of ketones in the urine. The strips may change varying shades of pink to purple, or may not change color at all. The container will have a scale on the label, with blocks of colour for you to compare the strip after a certain time lapse, usually 15 seconds. Most folks simply hold a strip in the flow of urine. Other folks argue that the force of the flow can "wash" some of the chemical away, and advise that a sample of urine be obtained in a cup or other container, then the strip dipped into it.
If you have a functioning pancreas that can produce insulin – i.e. you don’t have type 1 diabetes – it would be extremely hard or, most likely, impossible to get ketoacidosis even if you tried. That’s because high ketone levels result in release of insulin, that shuts down further ketone production. In other words, the body has a safety net that normally makes it impossible for healthy people to get ketoacidosis.
Enter keto cycling. Keto cycling involves following the keto diet for a certain amount of time and then having a day (or more) off. “It’s also called carb cycling,” says Molly Devine, RD, a Durham, North Carolina–based registered dietitian with KetoLogic, a website designed to educate people on keto. “That’s another term for it because there are higher-carb days and lower-carb days.”
Experts are split on whether the keto diet is a good idea. On the one hand, Lori Chang, registered dietitian and a supervisor at the Center for Healthy Living at Kaiser Permanente West Los Angeles, says using a “cleaner” source of energy—ketones rather than quick-burning carbohydrates—can improve mood and energy levels. When you eat refined carbohydrates or just too many carbs in general, the blood is flooded with excess insulin, Chang says. "This can lead to a blood sugar rollercoaster that stresses the body and negatively impacts energy levels and mood. When you’re in a state of ketosis, however, ketone bodies don’t require insulin to cross the blood-brain barrier, which wards off unfavorable blood sugar levels."
Since originally publishing this article, I’ve been asked whether elevating blood ketones with exogenous sources could trigger a ketone-induced release of insulin that would theoretically reduce hepatic ketogenesis and perhaps slow fat mobilization. This makes sense since you are putting more energy into the system in general (from exogenous ketones), so there would be less need to draw off your own fat stores.
Absolutely Steve. I love ranch salad dressing, cheese, cream cheese, steak, shrimp, and some vegetables. I am making “fakery” to satisfy my sweet tooth. (Fakery is baking using almond or coconut flour instead of wheat and white flour, and Swerve sweetener instead of sugar (made with Erythritol which has no impact on GI and is good for your teeth) I am over half way to my goal already. Thank you for your article. I appreciate your dedication, knowledge and sharing with the world. (and your cute animal gifs)
Why is the keto diet good for you? A keto diet is one that prioritizes fats and proteins over carbohydrates. It can help reduce body weight, acne, and the risk of cancer. Find out about the mechanisms through which it achieves these benefits and the research that supports it. This MNT Knowledge Center article also discusses the risks of the diet. Read now

In addition to adding in precious electrolytes such as potassium, magnesium, sodium, chloride, and calcium for supporting nerve impulses and muscle contraction, the Gaspari Nutrition R&D Team have also build their Osm Technology into this product. This “new way” of looking at carbohydrate drinks utilizes a proprietary method of tuning the electrolytes in solution with pure cyclic dextrin to get an optimal osmolality (mOsm). In a nutshell, this results in lower osmolality, and lower osmolality results in faster gastric clearance, and a clean, easy burn of your fuel.
The gut-brain link is important not only for the hormones produced by the gut, but also for the long-term body weight regulation. Studies in mice indicate that the gut microbiome influences both sides of the energy balance by contributing to nutrient absorption and regulating host genes that affect adiposity [however there are conflicting reports (Parks et al., 2013; Schele et al., 2013)]. However, it remains uncertain just how important gut microbiota are for nutrient absorption in humans. A cohort study has demonstrated that the nutrient load is a key variable that can influence the gut/fecal bacterial content over short time frames. Furthermore, the observed associations between gut microbes and nutrient absorption indicates a possible role of the human gut microbiota in the regulation of the nutrient intake and utilization (Jumpertz et al., 2011).
The BBB, largely formed by the brain capillary endothelial cells, provides a protective barrier between the systemic blood and the extracellular environment of the CNS. Passage of FAs from the blood to the brain may occur either by diffusion or by proteins that facilitate their transport. Studies indicate that FATP-1 and FATP-4 are the predominant FA transport proteins expressed in the BBB based on human and mouse expression studies (Mitchell et al., 2011).
I completely agree with you. It’s all about moderation and by the sound of this blog, you went too deep into it and didn’t allow yourself exceptions which are encouraged on keto at times. Being too strict with any diet is not a good thing. It sounds more like a borderline eating disorder which I have suffered from in my past. Different things work for different people and It’s about finding the right balance which also includes exercise. People want to lose the weight fast without having to work at it. It’s not just about losing the weight though, it’s about creating a healthier way of living whether it be with keto or not. My last suggestion is never step on the scale to guide your progress. Gauge it by how your clothes are fitting and how you are feeling because in the end, THAT is the only thing that matters. Best of luck to you.
Then there’s medium chain triglycerides (MCT’s). Most dietary fat has to be converted into water soluble molecules that then need to enter the liver via your lymph system. Your liver then converts these molecules to fatty acids and ketone bodies. But unlike most other forms of dietary fats, MCT’s can enter your liver directly without having to go through your lymph system. This means that consuming MCT’s gives your body an opportunity to quickly produce ketone bodies.
The Gatorade Sports Science Institute (GSSI) is widely considered one of the world’s top go-to resources for cutting-edge exercise and nutrition science advice – which is probably why Gatorade vending machines dot the campus here, and the majority of the kids seem to be walking around campus with a never-ending big gulp-sized cup full of sports drink.

Without peer-reviewed clinical trials, many of the benefits remain anecdotal. For instance, Weiss himself has been on a low-carb high-fat (though not strictly ketogenic) diet for more than six months, and claims he does feel much better. But he’s clear about what he knows and what he doesn’t. He’s lost weight and his borderline pre-diabetes is gone.
But sadly, whether due to government subsidy of high carb foods like corn and grain, funding from big companies like Gatorade and Powerbar, our sugar-addicted Western palates, or the constant (unfounded) fear mongering about saturated fats and heart disease, the type of research that shows these fat-burning and performance benefits of carbohydrate restriction simply get shoved under the rug.
Lower HbA1c: HbA1c is an abbreviation for ‘glycosylated hemoglobin.’ Hemoglobin is a protein inside red blood cells, this means it is always exposed to the substances that circulate in the blood (i.e glucose). When glucose levels are high, glucose can bind to hemoglobin (i.e it becomes glycoyslated). As red blood cells survive inside the body for 100-120 days, the amount of glyosylated hemoglobin is a good indicator of long term glucose control. The healthy limit for HbA1C is below 5.7% (Source: WebMD).
Some of the benefits of ketosis occur due to the restriction of dietary carbohydrate. Others occur due to the presence of ketones in the blood. Two of the most commonly sought after effects are weight-loss and improved insulin sensitivity. These are conferred by the low carbohydrate content of the diet allowing increased fat burning and the gradual restoration of insulin sensitivity. In this article we discuss the basics of ketone production and metabolism, and some of the many ways that KETONES themselves (endogenous AND exogenous) can benefit health and performance.
More recently a community of researchers and athletes have emerged who feel that following a ketogenic diet offers a performance advantage, especially to endurance sports where athletes are more likely to run out of stored carbohydrate during the event. However the evidence remains inconclusive and research is ongoing to provide a definitive answer to as to if a ketogenic diet offers a performance advantage.
I am an insulin dependent diabetic. I have been on a modified keto diet – mainly low-carbohydrate, increased good fats, and moderate protein. Though I have not lost any weight, my blood sugar stays in my target range and I have decreased my short term insulin intake by 75%. I see this as a good outcome. I would like to lose weight because I have arthritis and I think it would help my joints not to have to carry so much weight around. I am about 30 pounds overweight. What do you think of Low carbuhydratev for people who are diabetic and benefit so much from Keto ,I also practice intermittent fasting.
The keto diet changes the way your body converts food into energy. Eating a lot of fat and very few carbs puts you in ketosis, a metabolic state where your body burns fat instead of carbs for fuel. When your body is unable to get glucose from carbs, your liver converts fatty acids from your diet into ketones, an alternative source of energy. Burning ketones in place of glucose reduces inflammation and spurs weight loss.
Although convincing, the bulk of evidence in relation to the inhibitory effects of ketosis on appetite is still anecdotal. Preliminary scientific reports seem to support this phenomenon, and the evidence shows that KD is more effective, at least in the short/medium-term, on fat loss (Paoli, 2014). It was demonstrated that diet-induced weight loss leads to changes in energy expenditure and in appetite-regulating hormones that facilitate weight regain and the return to initial energy homeostasis (Sumithran et al., 2011). This response to alteration of energy balance nullifies the success of many dietary approaches. It is well-known that the long-term success of a nutritional approach is defined by the amount of weight regain and is the main problem regarding the so-called weight cycling or “yo-yo” effect (Jeffery, 1996). A recent study by our group has demonstrated that a brief ketogenic period, if followed by a longer period of correct Mediterranean diet could avoid this yo-yo effect (Paoli et al., 2013). During the ketogenic period subjects reported less hunger, confirming previous studies (Nickols-Richardson et al., 2005; Johnston et al., 2006; Johnstone et al., 2008) on hunger-suppression effect of ketogenic diet. Despite these clinical findings, the mechanisms of action of ketosis on appetite reduction are still not completely understood. Clinical results are suggestive of both direct and indirect (via modifications of hunger-related hormones concentration) actions of KBs on appetite (Sumithran et al., 2013).
But all those studies were very small, and not all research on the keto diet is as promising. One American Society for Clinical Nutrition study of 20 participants found that those on the diet didn’t lose more weight than those on a non-keto diet. But they did have fouler moods and higher levels of inflammation, which has been linked to a variety of conditions, including heart disease and cancer.
Your individual fat adaptation period. Remember your body needs time to become fat-adapted and that time depends on your metabolism. For instance, if you’re coming off a Standard American Diet (SAD) and your adult body has never ran on ketones before, your adaptation period might take a little longer. You’ll only experience the true weight loss effects of keto when your body is actually running on ketones.
