Ketone strips are not mandatory on a ketogenic diet, but you may find that having them on hand keeps you motivated and holds you accountable. On the other hand, you may find that testing your ketone levels is an added burden and prefer a more laidback approach. At the end of the day, it is a personal decision and comes down to what works best for helping you achieve your health goals. If you are meeting your goals of weight loss, decreased body fat, improved energy and focus, and/or better sleep, then a number on a meter or a color on a test strip is moot.

Urine test for diabetes: What you need to know Urine tests for diabetes check for protein, ketones, and glucose. They are frequently used for diagnosing and monitoring diabetes, and to assess people who are experiencing symptoms, such as fatigue or nausea. Depending on the results, recommendations may be given about medication or lifestyle changes that could help. Read now
Gentle Liver Cleanse I: Squeeze half a lemon into a warm or lukewarm glass of water first thing in the morning and drink it 20 minutes before breakfast. Cold water requires more time to process because calories must be used to warm it up before it can get to your liver. Warm or lukewarm water will access your liver much sooner. The lemon will act as a cleaning agent and can help to unclog your liver filter.
But it is true that premenopausal women may have some protection from high LDL (bad) levels of cholesterol, compared to men. That’s because the female hormone estrogen is highest during the childbearing years and it tends to raise HDL (good) cholesterol levels. This may help explain why premenopausal women are usually protected from developing heart disease.
Good heart health helps you power through everything from intense spin classes to late-night work deadlines. But fueling up with cookies and caramel lattes doesn't do your heart any favors. Research suggests added sugar can take a real toll on the cardiovascular system. A 2014 study revealed that people who consumed 17% to 21% of their daily calories from the sweet stuff had a 38% higher risk of dying from heart disease compared with those who kept their added sugar intake to 8% of their daily calories. The bottom line: Cutting back now will pay off big-time later.
Think about your body as a car. If you put gas in a car, it uses that fuel in order to move. In the same way, your body uses calories from food, or energy, in order for it to move, breathe and function. Metabolism is the process of your body utilizing the energy you put into it, or more simply, burning calories. You can also burn extra calories by adding activity, such as walking, dancing or exercising.
​A University of California, San Diego School of Medicine study finds that weight loss programs that provide healthy fats, such as olive oil in the Mediterranean diet, or a low-fat, high-carbohydrate diet have similar impacts on pound-shedding. More specifically, the researchers report that a meal plan rich in walnuts, which are high in polyunsaturated fats, has a significant impact on lipid levels for women, especially those who are insulin-resistant.
I realized that, despite my sweet tooth and my nightly bowl (okay, okay, scoops straight from the carton) of ice cream, I eat well and don’t have much to “cut out.” Sure, if I wanted to shed ten pounds and get to some elusive race weight, I could probably do it. But I’d have seriously sacrifice by cutting out all sweets and dialing back my caloric intake, which during marathon season, may not be as high as it should be anyway. So, chalk one up for me, for eating a pretty balanced diet and performing pretty well on the road.

For starters, your body uses up tons of energy every day just to support all of your basic functions—from breathing, to growing and repairing cells, to signaling different hormones. This is called your basal metabolic rate, and it accounts for 60 to 75% of calories you burn daily. Even if you were to spend the entire day hanging out on the couch or laying in bed, your body would still burn these calories.
Weight loss, from changes in diet and an increase in physical activity, is the primary treatment for most cases of fatty liver disease and NASH. In many cases, weight loss seems to have a very direct effect: as people lose weight, the fatty liver becomes less fatty. Crash dieting is a bad idea, though, because rapid weight loss (losing 4 pounds a week or more) can wind up damaging the liver. Of course, if sustained weight loss were easy, a lot of today's health problems would be solved, not just fatty liver disease and NASH.
Protein: When people first reduce carbohydrates in their diets, it doesn't seem as though the amount of protein they eat is as important to ketosis as it often becomes later on. For example, people on the Atkins diet often eat fairly large amounts of protein in the early stages and remain in ketosis. However, over time, some (perhaps most) people need to be more careful about the amount of protein they eat as (anecdotally) the bodies of many people seem to "get better" at converting protein into glucose (gluconeogenesis). At that point, each individual needs to experiment to see if too much protein is throwing them out of ketosis and adjust as necessary.
Depending on your metabolism, just one large cup of Bulletproof Coffee in the morning (without other foods) can raise blood ketone levels to levels that suppress appetite. At my buddy Zak’s house last year, I ate a lot of sushi with rice for dinner which ended my ketosis because I woke up with blood ketone levels of 0.1 mM, far below the appetite suppression levels in these studies. Then Zak handed me a large fresh-made Bulletproof Coffee. A half hour later, my blood ketone meter read 0.7 mM – more than enough to kick ass all day.
Meanwhile, the liver begins to burn fatty acids as an alternative energy source, resulting in the accumulation of extremely high levels of ketones in the blood.10 These ketone levels (> 20 mmol/L) can exceed normal fasting levels more than 200 to 300 times.1 Since ketones are mildly acidic, this deluge of ketones causes the blood to become excessively acidic (metabolic acidosis), increasing the risk of coma and death if not timely treated.
The first 2 weeks felt like I was bit hazy. I had a few nights of poor sleep and some long days at work during this time, but this felt different to the usual feelings of tiredness. After about 2 weeks something changed. I snapped out of my haze and suddenly felt more focused with more mental clarity than I’ve had in a long time. I’m guessing I went through a bit of a sugar detox.

What we know to be true is much simpler: "Sugar calories promote fat storage and hunger," the write. "Fat calories induce fullness or satiation." For every additional 150 calories in sugar (i.e., a can of soda) a person consumes per day, the risk for diabetes rises 11-fold, regardless of how much or little we exercise. The single most effective thing people can do for their weight, they write, is to restrict calories – and even more, restrict carbohydrates.


As a general rule, start with a ratio of 50 percent carbs, 30 percent fat, and 20 percent protein, and alter the ratio to suit your needs. Once you’ve found your proper ratio, remember that 1 gram of protein is 4 calories, 1 gram of fat is 4 calories, and 1 gram of carbohydrates is 9 calories. This will help you find the balance in your diet based on the calorie intake for your body type, age, and gender.
“When your liver is unhealthy,” Christianson told me in a recent interview, “you tend to store fat, especially around your midsection, plus you have a much harder time tapping into the nutrients you need to burn that fat.” That means that no matter what diet you choose and no matter how much willpower you muster, weight loss is pretty much impossible. Christianson says that the very definition of a slow metabolism is “a liver too overloaded to be able to store fuel temporarily.”

The effects of ketone drinks on endogenous insulin secretion are unclear. Whilst the small increase in plasma insulin after KE and KS drinks may have been due to the small quantity of dextrose in the diluent, it has been proposed that ketones could potentiate or even stimulate insulin secretion. Isolated pancreatic islets secreted insulin when stimulated by ketones at glucose concentrations of >5 mM (Biden and Taylor, 1983), and small amounts of insulin are secreted in vivo following exposure to exogenous ketones in animals (Madison et al., 1964; Miles et al., 1981). In response to an intra-venous 10 mM glucose clamp, ketone ester drinks increased glucose uptake and plasma insulin (Holdsworth et al., 2017). The increases in insulin with ketone drinks taken whilst fasted were small compared to the increases seen when the ketone ester drink was consumed with a meal and with consumption of a dextrose drink. Furthermore, the lack of difference in peak plasma insulin between the two latter conditions indicates that nutritional ketosis did not inhibit or increase normal carbohydrate induced insulin production.

Table 3 shows the kinetic indexes for VLDL, LDL, and HDL metabolism in the two groups. There were no significant group differences in lipoprotein kinetics at baseline. As before (13), weight loss significantly decreased the pool size (−41%, P = 0.007), concentration (−47%, P = 0.003), and production rate (−47%, P < 0.05) of VLDL apoB-100 but did not change VLDL apoB-100 FCR. There was a significant decrease (P < 0.05) in the weight loss group in the plasma LDL apoB-100 concentration (−24%) and pool size (−23%), as well as a significant increase in the LDL apoB-100 FCR (+27%), but no change in the LDL apoB-100 production rate. Weight loss was also associated with an increase in the percent conversion of VLDL apoB-100 to LDL apoB-100 (+23%, P < 0.01), and this increase was chiefly attributed to channelling via IDL (+16%, P = 0.06). The increase in LDL apoB-100 FCR was significantly correlated with the decrease in the pool size of LDL apoB-100 (r = −0.60, P < 0.01). Compared with weight maintenance, weight loss decreased HDL apoA-I production (−13%, P < 0.05) and FCR (−13%, P = 0.02), with no significant changes in the plasma concentration or pool size of HDL apoA-I. The changes in HDL apoA-I FCR and production rate were highly correlated (r = 0.72, P < 0.001). However, the changes in LDL and HDL FCR with weight loss were not statistically correlated.


High-fructose corn syrup is widely used commercially in the United States, and it may be more fattening than sucrose. In a study published in the "Medscape Journal of Medicine," Emory University researchers concluded that the liver metabolizes fructose more quickly than other types of sugars. When you give your liver more fructose than it can handle, it quickly turns the fructose to fat. Kimber Stanhope, a researcher at the University of California, conducted a study comparing types of sugar and found that people who consumed fructose burned less fat than people who consumed sucrose.
Meanwhile, the liver begins to burn fatty acids as an alternative energy source, resulting in the accumulation of extremely high levels of ketones in the blood.10 These ketone levels (> 20 mmol/L) can exceed normal fasting levels more than 200 to 300 times.1 Since ketones are mildly acidic, this deluge of ketones causes the blood to become excessively acidic (metabolic acidosis), increasing the risk of coma and death if not timely treated.
As described in the Newsweek article, I can personally affirm that weight loss can improve one’s liver. An ankle injury I suffered during a college football practice resulted in multiple surgeries and forced me to stop exercising, and I gained a significant amount of weight — in the neighborhood of 50 pounds. This resulted in high blood sugar and elevated liver enzymes, indicating potential damage to my liver due to fatty liver disease. My physician prescribed anti-diabetic medication, but I decided it was best to focus exclusively on losing weight. I was successful in losing approximately 10% of my body weight, and although I am continuing to try it is a constant struggle.
"Most people I have worked with don't benefit from VO2 max testing," he says, explaining that the test can be discouraging if a client thinks they are in better shape than they are. "I don't like delivering discouraging news, so I only do VO2 max if either someone is completely lost, very stubborn and apparently unfit (to give them objective data), or very fit and wants to know their numbers."
Over the 10 days, I became very comfortable with a nutrition label and the numerous different terms for hidden sugar. Every single meal, snack, and drink had to be carefully vetted to ensure it met the requirements. The amount of sugar in sauces and dressings surprised me. I bring salads to work almost every day for lunch, and two tablespoons of dressing alone could have 15 grams of sugar. Makes you think twice about adding a little extra! (Should Added Sugar Appear On Food Labels?) But I was pleasantly surprised to learn prepared hummus doesn't contain added sugar, and when mixed with plain Greek yogurt, it's a great substitute for dressing.

Some research suggests that ketogenic diets might help lower your risk of heart disease. Other studies show specific very-low-carb diets help people with metabolic syndrome, insulin resistance, and type 2 diabetes. Researchers are also studying the effects of these diets on acne, cancer, polycystic ovary syndrome (PCOS), and nervous system diseases like Alzheimer's, Parkinson's, and Lou Gehrig's disease.

The first step was filling out daily logs of everything I ate, when, where and even why — for example, whether I felt hungry before eating. This exercise helps determine whether clients eat because they’re hungry or to fill a psychological need. The logs are also designed to find out how much saturated fat or trans-fat people consume, in foods such as hamburgers or many baked goods.
Unless otherwise stated, statistical analysis was conducted using Prism 6™ software. Values, expressed as means ± SEM, were considered significantly different at p < 0.05. Initial tests were undertaken to ensure that normality and sphericity assumptions were not violated. Subsequently, either one or two way repeated measures ANOVA, or Freidman's test with post-hoc Tukey or Dunnet's correction were performed, to compare changing concentrations of substrates, electrolytes, pH, insulin, breath and urinary βHB: both over time and between study interventions. In Study 2, data from each of the two study visits in each condition (fed and fasted) completed by an individual were included in the analysis.
Healthy, physically active individuals generally have an appropriate BMI, body mass index, and are within their ideal body weight range. This means that the calories they are ingesting are being utilized for energy and to maintain their normal body weight in a balance ratio. When we become less active or ingest more calories than we are using for energy and activity, those additional, unused calories are stored as fat in our adipose tissue.
What are the benefits of activated charcoal? Many people use activated charcoal, often in a drink, for its claimed health benefits, including the removal of toxins and promotion of kidney health. It is safe for most people, and there are no reported risks or adverse reactions. But what does the science say about the benefits of activated charcoal? We find out. Read now

Plus, in the last 30 years, exercise has stayed about the same, while overweight and obesity have skyrocketed. So something else must be at play – like the type of food we’re eating. That part has gotten steadily worse over the years, as highly-processed sugary foods and sodas have taken over as our go-to choices. “According to the Lancet global burden of disease reports,” they write, “poor diet now generates more disease than physical inactivity, alcohol and smoking combined.” This is a disturbing statistic. But it gets worse.
As you might expect, I felt great for the first few days. The key word there is “felt.” A couple of days wasn’t long enough for the change to have had a physical effect or move the needle on the scale. Maybe it would have if I’d been eating nothing but fast food for three meals a day. But I had gotten so excited at the prospect of cutting back on my sweet tooth that it boosted my motivation. At the end of the 30 days, however, I didn’t end up feeling any different.

Your liver is the brain of your body and it must work right for your metabolic and fat burning ability to be normal and healthy. Getting your liver to work better takes time and requires that you engage weight loss as a trend. Your basic tools for doing this are following the Leptin Diet, exercising consistently, and taking basic dietary supplements that support weight management as explained in the first article in this series.

BS, KC, and PC designed the research studies. BS, PC, RE, SM, and PS carried out the studies. SH provided the gas analyser used in the study on behalf of NTT DOCOMO Inc. BS, MS, and SM analyzed the data and performed statistical analysis in collaboration with JM. BS wrote the paper with help from KC, PC, and OF. KC had primary responsibility for final content. All authors read and approved the final manuscript.
We keep talking about “energy” without mentioning a way to measure it.  One useful way to measure energy is in calories – whether we’re measuring the energy in foods or the energy our bodies expend, we can measure both in calories.  There are sophisticated ways of measuring metabolism that we use in physiology labs, but most of us will never know how many calories we use at rest, and it probably doesn’t matter.
As you continue on the diet, you become more adapted or accustomed to making and burning ketones. More ketones are reabsorbed and used for energy, and fewer ketones overflow into the urine.15 After several weeks, as ketone levels rise, evidence suggests your muscles shift to burning fatty acids directly while burning fewer ketones. In this way, ketones are spared for use by other tissues, particularly the brain (which does not burn fatty acids for fuel).16,17
NAFLD may not be discovered until blood tests show an elevation in certain liver enzymes. Additional blood tests may be ordered to rule out other causes of liver disease. To confirm the presence of fat in your liver, doctors often perform an imaging procedure — such as ultrasound, computerized tomography (CT) or magnetic resonance imaging (MRI) — and may also recommend a liver biopsy to examine a sample of tissue for signs of inflammation and scarring.
For all studies, the area under the curve (AUC) of blood [βHB] was calculated using the trapezium rule. In Study 3, for each of the three drinks, the initial rate of d-βHB appearance was estimated using d-βHB concentrations at baseline and 30 min post-drink, and d-βHB elimination was estimated using the AUC between the post-drink peak (60 min) and trough (180 min) d-βHB concentrations, with a baseline correction to the value at 180 min.
This was about cutting back, not depriving myself and feeling miserable, so if something came up (a work birthday party, a nice dinner with dessert), I wouldn’t turn it down. Besides, I’ve learned over the years that it’s easier to form good habits if you’re not so strict with yourself. A total sugar deprivation probably would have lasted until day two. Okay, okay, day 1.5.

Diet diaries at t = 0 and t = 3 months revealed a 43% decrease in energy intake (p<0.0001) and a 52% reduction in total fat content (p<0.0001), and energy from saturated fat decreased from 13 (1)% to 10 (1)% of total energy intake per day (p = 0.005). The decrease in energy intake reported would be expected to result in greater weight losses than were observed (approximately 1 kg/week). Systematic underreporting of dietary intake is common in overweight patients and should be considered when assessing dietary composition. At enrolment there was no difference in dietary macronutrient composition between patients with HCV and non-HCV related liver disease. There was no association between macronutrient composition and insulin resistance.
Normally, fatty acids are oxidized to become energy with the help of some hormones, but insulin prevents lipolysis and hampers the breakdown of adipose tissue. This results in free fatty acids being released into the bloodstream which leads to an accumulation of triglycerides. Higher levels of triglycerides are also associated with higher levels of LDL-cholesterol and lower levels of HDL-cholesterol (12).

First, let’s be clear: There’s no such thing as miracle metabolism boosters. No matter what you see in ads or hear in your running circles, there are no special supplements or super foods that can blast off unwanted pounds while you sleep. But you can and should take steps to keep your metabolism running at its hottest, because the same steps you take to stoke your calorie burn also improve your athletic performance and help keep you healthier for life.

Your fasting triglycerides should never be more than twice as high as your HDL cholesterol number. The best chance you have of clearing triglycerides from your blood is by not snacking between meals (Rule #2) and not eating after dinner at night (Rule #1). Of course, if you eat meals that are too large (violating Rule #3) you simply overwhelm your liver with too much to do. When your triglyceride number comes down you have created an environment wherein your liver now has the potential to dump clogged fat. Conversely, when your triglyceride number stays elevated--even if you are eating better--it is reflective of a liver clogged with fat.


Obese individuals who walked on a treadmill7 for one hour per day improved insulin resistance, boosted adiponectin levels, lowered free radical damage, and improved fatty liver problems. Another study showed that placing sedentary obese adults on a four week aerobic cycling8 and stretching program cleared out 21 percent of their liver fat, clearly helping to unclog their livers.
If your doctor has advised you to lose weight, then it can help to know that even a little weight loss makes a big difference to your health. Losing just 10% of your body weight will help lower your cholesterol and triglyceride levels, your blood pressure, your risk of diabetes and your risk of some types of cancer. It also takes the stress off your joints, making it easier to move about.
However, environmental influences are probably significantly more important. The Tarahumara Indians of northwestern Mexico, for example, traditionally have low cholesterol levels; you could say “it’s in their genes.” But a study by scientists at Oregon Health Sciences University found that the Tarahumaras’ cholesterol levels rose sharply, and in just a few weeks, when they were directed by the researchers to switch from their traditional fiber-rich, plant-based diet to a Western-style diet full of cheese, butter, oils, egg yolks, white flour, soft drinks, and sugar.5

When your body is severely deprived of energy (calories), it resorts to breaking down both fat and lean tissue (such as skeletal muscle) to generate fuel. Intuitively, the goal of a ketogenic diet is to increase body fat breakdown so it can be burned as fuel, but when you greatly restrict your calorie intake, you significantly increase lean tissue breakdown as well.

One of the best ways to cut sugar from your diet is to focus on noshing whole foods instead of packaged, processed foods, like cookies, cake, candy, granola bars, and cereals. Whole foods include fruits, veggies, whole grains, nuts, and seeds. Although your body may by now be primed to crave sugar, the more whole foods you eat, the more you’ll come to enjoy them. “Your taste buds will adapt,” Lemond says.
“We could have found out that if we cut carbs, we’d lose way more fat because energy expenditure would go up and fat oxidation would go up,” said Kevin Hall, an obesity researcher at NIH and an author on many of these studies. “But the body is really good at adapting to the fuels coming in.” Another related takeaway: There appears to be no silver bullet diet for fat loss, at least not yet.
