Hello, I have a quick question. I’ve been on keto since March 2017. Already lost about 45 pounds, down to 140 at 5’7 and about 16.4% fat. I take a magnésium cap each morning to be sure I got enough and eat at least 1 serving of baby spinach a day with olive oil or fatty dressing that have no carbs. My last meal is always between 5 and 9 pm (mostly around 6) and I don’t eat back before 12pm the next day on week days and not before next dîner on week end. Fasting isn’t something new to me and when I read it help getting in ketosis I continued.

It’s also important to note there have been no long-term studies on the ketogenic diet, nor has there been research that details what may happen to the body if it’s in a constant state of ketosis itself. But given how the body needs carbs to function properly, diets that are based on fat burning may lead to nutritional deficiencies, and supplements and multivitamins are recommended because you’re cutting out entire food groups, warns Alyssa Rothschild, RDN, who is in private practice in New York City.

Thank you for this article as it cleared up a bunch of stuff for me. I started trying to get into ketosis back in August and lost 20lbs in about 6 weeks. Then it all stopped but had another 20lbs I wanted to loose. I had a hard time staying in ketosis and gave up about a week ago with the holidays approaching. Anyways I glazed over all the technical and science facts as it makes my head spin and might of missed it but my only question is what is the food portion of the diet like? The drinks are the easy part, do you have a diet plan that is good for someone that hits the gym hard 4-5 days a week for and hour and half. 45 min weights and 30-45 min cardio? It’s what I struggle with most the food and what attracted me to a ketogenic diet in the first place is eating 1 or 2 meals a day and being satisfied.
Easy: use about half of the recommended serving of Glycofuse, and instead add one scoop of Catalyte electrolytes, one scoop of Kion Aminos, and one serving of ketones and/or MCT’s in the form of Brain Octane, KetoCaNa or KETO//OS (pick your poison, it’s up to you). While any of these forms of ketones and/or MCT’s works for daily focus and short workouts, I found that for long workouts they aren’t very gut friendly unless you really spread out the dosage (e.g. one serving every three hours), so you’d only really use that stuff in something like, say, an Ironman triathlon or multi-day adventure race.

People use a ketogenic diet most often to lose weight, but it can help manage certain medical conditions, like epilepsy, too. It also may help people with heart disease, certain brain diseases, and even acne, but there needs to be more research in those areas. Talk with your doctor first to find out if it’s safe for you to try a ketogenic diet, especially if you have type 1 diabetes.


This benefit surprised me when I first discovered it, but eating fewer carbohydrates during a workout can actually help you recover from workouts faster. The repair and recovery of skeletal muscle tissue is dependent on the “transcription” of certain components of your RNA. And a bout of endurance exercise combined with low muscle-carbohydrate stores can result in greater activation of this transcription. In other words, by training in a low-carbohydrate state, you train your body to recover faster.
A: The most common ways to track your carbs is through MyFitnessPal and their mobile app. You cannot track net carbs on the app, although you can track your total carb intake and your total fiber intake. To get your net carbs, just subtract your total fiber intake from your total carb intake. I have written an article on How to Track Carbs on MyFitnessPal.
First, I want to thank you for all of your dedication and work in providing this site. The difficulty of maintaining a healthy weight is a big problem for so many people. My personal question & issue in staying on Keto is my craving for fresh fruit. This a.m I had a large fresh peach along with my “Bullet Proof” coffee. Have I now sabotaged today’s Keto eating?
I see a lot of people say that ketosis is great for insulin sensitivity. BUT, in my experience ketosis causes physiological insulin resistance whereby the muscles and liver are sparing glucose for the brain. Hence, glucose tolerance actually goes down during ketosis. As such, is it possible that post workout carbs could do a lot more damage than they would on a non-ketogenic diet? Or maybe, as Kiefer suggests, glucose uptake post workout is not moderated by insulin at all i.e. muscles soak up glucose regardless of their insulin sensitivity? Or maybe cyclical ketosis doesn’t allow liver glycogen to get low enough to trigger physiological insulin resistance?

Awesome… I am a newbie to this i took the keto os for 2 months for weight loss and did well. It a bit pricey. I try hard to conform to lchf diet daily but see no change other than I crave sweets. In 5’7 270 and stuck! My highest weight was 390 had gastric band put in 10 years ago but its just keep me from consumption of large amounts at on time. Is there a more economical way to stay in ketosis? I wAnt more energy… In not an exercise person usually have no energy. In willing to try other ideas.

After initiation, the child regularly visits the hospital outpatient clinic where they are seen by the dietitian and neurologist, and various tests and examinations are performed. These are held every three months for the first year and then every six months thereafter. Infants under one year old are seen more frequently, with the initial visit held after just two to four weeks.[9] A period of minor adjustments is necessary to ensure consistent ketosis is maintained and to better adapt the meal plans to the patient. This fine-tuning is typically done over the telephone with the hospital dietitian[19] and includes changing the number of calories, altering the ketogenic ratio, or adding some MCT or coconut oils to a classic diet.[18] Urinary ketone levels are checked daily to detect whether ketosis has been achieved and to confirm that the patient is following the diet, though the level of ketones does not correlate with an anticonvulsant effect.[19] This is performed using ketone test strips containing nitroprusside, which change colour from buff-pink to maroon in the presence of acetoacetate (one of the three ketone bodies).[45]
Thanks for all of the great info!! I have Hashimoto’s and would really like to try a high fat/low carb diet. You mentioned that this might not be a good option for people with thyroid issues. How do you recommend I modify my diet to lose weight taking into consideration the Hashimoto’s. I take Westhroid, a non-synthetic thyroid supplement to help with my sluggish thyroid. Thanks so much for any advice you can give me. :)
Jalali says people following the diet have the best chance of keeping the weight off if they stay on it long term. And that’s not always easy to accomplish. The weight may come back if you go back to your regular eating habits. And regaining weight may lead to other negative effects. “Chronic yo-yo dieting appears to increase abdominal fat accumulation and diabetes risk,” notes Clark.
If you want to make some enemies very quickly, just jump on to social media and say "the keto diet stinks." Because there are certainly a number of people who swear by the keto diet. Some of them will even swear at you if you say anything bad about the diet. Supporters of the diet claim that the keto diet will help lose weight relatively quickly, clear your mind, make you feel better, and even clear up your acne, because you no longer are taking in carbohydrates that "cause inflammation." People who question the diet have raised concerns about whether maintaining such a high fat diet is effective and healthy in long run. After all, high fat diets could raise the risk of various chronic medical conditions such as heart disease and cancer.

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.
Implementing the diet can present difficulties for caregivers and the patient due to the time commitment involved in measuring and planning meals. Since any unplanned eating can potentially break the nutritional balance required, some people find the discipline needed to maintain the diet challenging and unpleasant. Some people terminate the diet or switch to a less demanding diet, like the modified Atkins diet or the low-glycaemic index treatment diet, because they find the difficulties too great.[42]
If you're healthy and eating a balanced diet, your body controls how much fat it burns, and you don't normally make or use ketones. But when you cut way back on your calories or carbs, your body will switch to ketosis for energy. It can also happen after exercising for a long time and during pregnancy. For people with uncontrolled diabetes, ketosis is a sign of not using enough insulin.
What would your advice be to a high raw vegan who wants to try an HRV keto diet? The supps you recommended above look vegan, but aren’t the results based on those of omnis? Would they work the same way on vegans? Also I heard you mention in the recent Keto Summit that SE Asians need a little more carb and I happen to be one. I’m a petite 39-YO female and I’ve been raw for the past 11 years. I have been practicing intermittent fasting in the last 7 years and try to eat only twice a day. Up to how many grams of carbs can I consume to get into ketosis?

In one week my husband lost 1.5 kg because of Keto diet and recipes. Thank you for the insights and tips. I would like to have a complete recipe for meals everyday and hoping by subscribing I will receive try my mail. I will keep u posted. It takes 2 to tango. The one who wants to diet must be cooperative with the plan and execution while the other person who is preparing the food must be patient to the dieting person. Its not easy to change meals so patience is required
Strawberries are another delicious, sweet, and filling fruit that you can eat in moderation on the keto diet. A ½-cup serving of sliced strawberries contains about 4.7 g of net carbs and 4.1 g of sugar. As there are only 27 calories in the aforementioned serving, you can eat strawberries raw, add a few pieces to your cereal, or blend a handful into a small low-carb smoothie. Strawberries also have antioxidant and anti-inflammatory benefits, per a study published in February 2010 in the Journal of Medicinal Food. The same ½ cup provides 48.8 mg of vitamin C (81.3 percent DV), 127 mg of potassium (2.7 percent DV), and 20 micrograms of folate (5 percent DV).
It is possible to combine the results of several small studies to produce evidence that is stronger than that available from each study alone—a statistical method known as meta-analysis. One of four such analyses, conducted in 2006, looked at 19 studies on a total of 1,084 patients.[23] It concluded that a third achieved an excellent reduction in seizure frequency and half the patients achieved a good reduction.[18]

I know, I know you’d think with all these side effects I’d just give up on ketosis! but I enjoy the mental clarity and I have a lot of food sensitivities and gut and yeast problems and don’t tolerate carbs well either so I feel stuck between a rock and a hard place. Not craving what I can’t have constantly is LIFE CHANGING! (34 year old female with chronic fatigue, thin, hike for exercise).

Meat – like grass-fed selections – and fresh veggies are more expensive than most processed or fast foods. What you spend on Keto-friendly foods will vary with your choices of protein source and quality. You can select less-expensive, leaner cuts of meat and fatten them up with some oil. Buying less-exotic, in-season veggies will help keep you within budget.

Carbohydrates have been linked to this skin condition, so cutting down on them may help. And the drop in insulin that a ketogenic diet can trigger may also help stop acne breakouts. (Insulin can cause your body to make other hormones that bring on outbreaks.) Still, more research is needed to determine exactly how much effect, if any, the diet actually has on acne. 


Peak fat oxidation was 2.3-fold higher in the LC group (1.54 ± 0.18 vs 0.67 ± 0.14 g/min; P = 0.000) and it occurred at a higher percentage of VO2max (70.3 ± 6.3 vs 54.9 ± 7.8%; P = 0.000). Mean fat oxidation during submaximal exercise was 59% higher in the LC group (1.21 ± 0.02 vs 0.76 ± 0.11 g/min; P = 0.000) corresponding to a greater relative contribution of fat (88 ± 2 vs 56 ± 8%; P = 0.000). Despite these marked differences in fuel use between LC and HC athletes, there were no significant differences in resting muscle glycogen and the level of depletion after 180 min of running (−64% from pre-exercise) and 120 min of recovery (−36% from pre-exercise).

The nerve impulse is characterised by a great influx of sodium ions through channels in the neuron's cell membrane followed by an efflux of potassium ions through other channels. The neuron is unable to fire again for a short time (known as the refractory period), which is mediated by another potassium channel. The flow through these ion channels is governed by a "gate" which is opened by either a voltage change or a chemical messenger known as a ligand (such as a neurotransmitter). These channels are another target for anticonvulsant drugs.[7]

It is, however, worth noting that according to the customary convention (Woodyatt, 1921 ; Shaffer, 1921) this diet is not ketogenic since the ratio of ketogenic(FA) to ketolytic (G) aliments is 1.09. Indeed, the content of fat would have to exactly double (324 g daily) to make the diet ketogenic (FA/G>1–5).

Keto-adaptation, AKA “becoming a fat burning machine”, occurs when you have shifted your metabolism to relying on fat-based sources, instead of glucose (sugar) sources, as your primary source of fuel. Your body increases fat oxidation, and breaks down fats into ketones to be used as the primary energy source. Depending on your current level of carbohydrate intake (takes longer if you’re pretty sugar addicted), this process can take two weeks to six months to fully train your body to, but once done, it’s done, and you have achieved fat-burning status that can stick with you for life.

What is the link between ketones and diabetes? Ketone is a chemical produced by the body when fats are broken down for energy. Ketone testing is important for people with diabetes, because high levels can lead to diabetic ketoacidosis (DKA), when acid levels become too high in the blood and the person loses consciousness. Find out when and why to do ketone testing. Read now

On a ketogenic diet, your entire body switches its fuel supply to run mostly on fat, burning fat 24-7. When insulin levels become very low, fat burning can increase dramatically. It becomes easier to access your fat stores to burn them off. This is great if you’re trying to lose weight, but there are also other less obvious benefits, such as less hunger and a steady supply of energy. This may help keep you alert and focused.
Acetyl-CoA can be metabolized through the TCA in any cell, but it can also undergo a different process in liver cells: ketogenesis, which produces ketone bodies.[27] Ketone bodies are also produced in mitochondria, and usually occur in response to low blood glucose levels.[28] When glucose levels are low, oxaloacetate is diverted away from the TCA cycle and is instead used to produce glucose de novo (gluconeogenesis). But when oxaloacetate is unavailable to condense with acetyl-CoA, acetyl-CoA cannot enter the cycle, and so the body has evolved an alternative way to harvest energy from it.
The day before admission to hospital, the proportion of carbohydrate in the diet may be decreased and the patient begins fasting after his or her evening meal.[19] On admission, only calorie- and caffeine-free fluids[37] are allowed until dinner, which consists of "eggnog"[Note 8] restricted to one-third of the typical calories for a meal. The following breakfast and lunch are similar, and on the second day, the "eggnog" dinner is increased to two-thirds of a typical meal's caloric content. By the third day, dinner contains the full calorie quota and is a standard ketogenic meal (not "eggnog"). After a ketogenic breakfast on the fourth day, the patient is discharged. Where possible, the patient's current medicines are changed to carbohydrate-free formulations.[19]

You said you saw Dr. Jeff Volek at UCONN. I am interested in ketosis to help me with my M.S. I still have questions related to M.S. and not so much as it effects on athletes. I do live in CT, but was unable to locate Dr. Volek at either the Storres or Farmington campus. Would you be able to give me either his e-mail address or telephone number so that I can contact him directly? Your help would be greatly appreciated.
After about two to seven days of following the keto diet, you go into something called ketosis, or the state your body enters when it doesn't have enough carbs for your cells to use for energy. That's when you start making ketones, or organic compounds that your bod then uses in place of those missing carbs. At this point, your body also starts burning fat for more energy, says Beth Warren, R.D., founder of Beth Warren Nutrition and author of Living A Real Life With Real Food.
Hi Ben, great article. I have been a keto-adapted athlete for over 2 years, all through nutrition (65/25/10). I have recently discovered UCAN, KetoOS and MAP Aminos. So, here’s my question: If I am going out for a 4-hour ride, and I want to fuel myself just on these supplements and my body’s natural fat stores, how and in what order should I take them? If I take them all together, will the aminos in the KetoOS interfere with MAP Aminos? Or should I just make a mix of the UCAN and KetoOS in 10oz of water and use it to wash back my 6 MAP tablets, 15-mins before my ride? Thanks for your advice!
I've tried that before(enzymedica digest gold for example) but it didn't seem to help much. It seems from testing that I have some heavy metal stuff going on and there might have been a chronic mold exposure in the past that is still reeking havoc and I imagine that might be affecting this pretty heavily. I will definitely be sticking to the avocadoes and coconut and 100% dark chocolate because I can't tolerate dairy. The hard part is figuring out what is the bare minimum of starch to make my gut feel good and be regular and at the same time become fat adapted and get those increased cognition and longevity benefits!!

In the US especially, coconut oil and MCT oil manufacturers are legally allowed to claim that lauric acid is an MCT because chemists named it that way, even though it does not act like other true biological MCT oils. If you are relying on plain coconut oil or “MCT-labeled” oil to get enough useful MCTs, think again and check the label: odds are you’re getting very few of the potent, ketogenic shorter chain MCTs (also known as “C8” and “C10”), and instead getting mostly cheaper but ineffective lauric acid.
As a matter of fact, it’s more dangerous to have high levels of cholesterol and high levels of CRP than low levels of cholesterol and high levels of CRP – even if your high levels of cholesterol are “healthy”, big fluffy LDL particles, and not small, dense vLDL particles. In other words, no matter how many healthy fats you’re eating, these fats may actually come back to bite you if you’re creating high inflammation from too much exercise, not enough sleep, exposure to toxins and pollutants, or a high-stress lifestyle.
I don’t know about you, but I find these risks pretty damn concerning. The fact is that I want to be around to play with my grandkids, and considering that my genetic testing with 23andMe has revealed that I have a higher-than-normal risk for type 2 diabetes, I doubt that shoving more gooey gels and sugary sports drinks into my pie hole is going to do my health any favors. So if I can achieve similar levels of performance and body composition with carbohydrate restriction, I’m all in.
Perhaps you fall into the category of Olympic athletes who would dope with damaging drugs, even if they knew it would kill them. However, if you desire a long, high-quality life, you don’t want to be a washed up ex-exerciser with diabetes, or you don’t want to experience joint, nerve and brain inflammation, damage and degradation, you may need to adjust your lens.

People on the diet report being significantly more full and satisfied. Even though you may be ingesting LESS calories on the diet, your hunger doesn't increased. One possible explanation is greater consumption of satiating foods, primarily protein and fat. However, multiple studies indicate that the state of ketosis itself (apart from effects from food) plays a role as well.10
-Pancreatic Dysfunction: The beta cells in the pancreas that produce the insulin to help control blood sugar become dysfunctional with high blood glucose, raising the risk for type 2 diabetes. Researchers have discovered that beta cell issues are detectable in people whose glucose levels spike two hours after eating, despite those levels staying within the range considered normal and safe by the medical establishment.
