Sleep enough – for most people at least seven hours per night on average – and keep stress under control. Sleep deprivation and stress hormones raise blood sugar levels, slowing ketosis and weight loss a bit. Plus they might make it harder to stick to a keto diet, and resist temptations. So while handling sleep and stress will not get you into ketosis on it’s own, it’s still worth thinking about.

Some people on a keto or low carb diet choose to count total carbs instead of net carbs. This makes it more difficult to fit in more leafy greens and low carb vegetables (which are filled with fiber), so you should only try that if you don’t get results with a net carb method. And, start with reducing sugar alcohols and low carb treats before deciding to do a “total carbs” method.

Freezing does stop the postmortem metabolism but only at about −18ºC and lower temperatures. Above −18ºC increasing temperatures of storage cause an increasing rate of ATP breakdown and glycolysis that is higher in the comminuted meat than in the intact tissue (Fisher et al., 1980b). If the ATP concentration in the frozen tissue falls below ~ 1 µmol/g no contraction or rigor can occur because they are prevented by the rigid matrix of ice.
Whether ketosis is taking place can be checked by using special urine test strips such as Ketostix. The strips have a small pad on the end, which the user dips in a fresh urine specimen. Within seconds, the strip changes color to indicate the level of acetoacetate ketone bodies, which reflects the degree of ketonuria, which, in turn, gives a rough estimate of the level of hyperketonemia in the body (see table below). Alternatively, some products targeted to diabetics such as the Abbott Precision Xtra or the Nova Max can be used to take a blood sample and measure the β-hydroxybutyrate ketone levels directly. Normal serum reference ranges for ketone bodies are 0.5–3.0 mg/dL, equivalent to 0.05–0.29 mmol/L.[29]

I’ll warn you: when you first start using BHB salts like KetoCaNa, it can cause some temporary GI upset until you get acclimated to use. For me, this manifested in just a little bit of gas and bloating that subsided after about one week of use. Additionally, you should know that this product contains salt, so it counts as part of your daily salt intake.

The DNA test does not necessarily take into account your goals (e.g. breathholding, Ironman, cognition, etc.) and if your goals would benefit from ketosis, then you may want to choose it as a dietary strategy even though it could indeed be true that for FAT LOSS a higher carb intake may suit you. So it all depends on your goals. Or you could just us the supplements like ketones AND eat more carbs and get "best of both worlds". 

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.

I'm at 240 now and actually weigh less than I did in high school. Have a decent amount of excess skin that skews my actual weight. Thankfully the government of Canada pays for plastic surgery in my case because it could lead to health problems in the future. Surgery is in about 8 or so months and I'm quite excited to start a completely new chapter of my life once it's done.

The bottom line is that there have not been enough scientific studies, especially longer term ones, to really determine all the potential risks and benefits of the keto diet. Many of the claims out there on the Internet, social media, or television in either direction are anecdotal, meaning that they are individuals telling stories about what has supposedly been their experiences. Take everything you hear that is not supported by scientific evidence with a grain of salt (but not too much salt because too much can be bad for you.)

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.
I was thinking of buying exogenous ketones for my mother. She plays golf daily but gained some weight as of late. My mother does not want to do the diet but I was thinking this might help her with energy and losing weight. Another person told me it would help her. But then I got to thinking, if she went into Ketosis, then wouldn’t she get the keto flu rather than get energy and mental clarity? Would I need to tell her to take it everyday?
I am new to Keto, but not new to a low carb diet. I just started a keto diet 8 days ago. My goals for being on the diet is a little body recomp (nothing major, a few pounds of fat loss), and moving to fat as primary fuel for endurance with a focus on trail ultra marathon races and training. Along with Keto I am doing heart rate training using MAF and OFM as a guide. supplemented with body weight and free weight strength training and some HITT.
In a state of ketosis, your body breaks fat down in the liver and converts it into ketones to be used for energy. Fat doesn't generate an insulin response, so insulin levels remain stable. This makes it much harder to store excess fat, and easier to tap into body fat stores for energy. Not only will this allow you to maintain your weight, but it will greatly encourage weight loss.
I have that thing on a “real” ketogenic diet where I wake up at 3 am with my mind/heart racing and can’t sleep. It happens the very first day I reduce my carbs and continues as long as my carbs are reduced (5 weeks is the longest I’ve been able to put up with this to see if I could fix it and stay ketogenic). Magnesium and/ or cal-mag before bed does not help. Is carb loading at night the only hope for fixing this? I already take great care with bluelight and EMF.
"Some people stop working with me because they're not going to be proven wrong. You’re dissing their religion," said Libby, a registered dietician who asked that her full name not be used because of the private hate messages she's received from the community.   “If there was a diet or a pill or something that really was this miracle diet weight-loss thing that lasted and was healthy for you, we wouldn't have all these different diets all the time, there wouldn't be health complications, there wouldn't be so much controversy about it and the first time that you'd be learning about it wouldn't be on a 3pm talk show."
Kidney stones are a well-noted potential side effect of the ketogenic diet. Research published in the Journal of Child Neurology observed that among children following the keto diet as a treatment for epilepsy, 13 out of 195 subjects developed kidney stones. Children supplementing with potassium citrate in the study noticed a decreased likelihood of kidney stones. Speak with your healthcare practitioner about supplementing if kidney stones are a concern.
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.
Because the ketogenic diet alters the body's metabolism, it is a first-line therapy in children with certain congenital metabolic diseases such as pyruvate dehydrogenase (E1) deficiency and glucose transporter 1 deficiency syndrome,[35] which prevent the body from using carbohydrates as fuel, leading to a dependency on ketone bodies. The ketogenic diet is beneficial in treating the seizures and some other symptoms in these diseases and is an absolute indication.[36] However, it is absolutely contraindicated in the treatment of other diseases such as pyruvate carboxylase deficiency, porphyria, and other rare genetic disorders of fat metabolism.[9] Persons with a disorder of fatty acid oxidation are unable to metabolise fatty acids, which replace carbohydrates as the major energy source on the diet. On the ketogenic diet, their bodies would consume their own protein stores for fuel, leading to ketoacidosis, and eventually coma and death.[37]
Sensational article. I am experimenting with a low carb diet, high fats and moderate protein. I am not keeping strict notes on what I eat but I cut out almost all fruit and I eat eggs, spinach, kale, chard, avacados, hard cheese, walnuts (raw organic) and grass fed meet and butter. I take about 25-30ml of Brain Octane straight a day. I take your probiotic and colostrum (I need to get more regular) and I consume bone broth four days a week. I am looking to live longer and be healthier during that long life. In the short term I want to be smarter and be able to handle stress better. I would also love to avoid cancer and drop a deuce every day. My question is: Is there a point of carb consumption where even combining it with exogenous ketones using your recommendations it would be less effective or cause negative outcomes? Could one consume all the cards and sugar one wanted and use the supplements and still be getting into ketosis and reaping the benefits?
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?
Lemons are also keto-friendly, so go ahead and add a spritz of lemon juice to your ice water. One typical lemon wedge has about 0.5  g of net carbohydrates and only 0.2 g of sugar. The fruit also offers  3.7 mg of vitamin C, which is 6.2 percent of the DV. Lemon water contains antioxidants that fight free radicals, and it also promotes healthy digestion, according to the Cleveland Clinic.
Ken, not 100% sure I understand your question but if you're asking if you should take any more supplements through out the week, it's hard to know without getting some blood testing done. If you want to go into detail, book a consult at bengreenfieldfitness.com/coaching and choose 20 or 60 mins and we'll get you scheduled. If you want to know specifically about fueling for your runs, have a read through this: https://bengreenfieldfitness.com/2013/07/what-…
The ketogenic diet typically reduces carbohydrate intake to less than 50 grams per day — and calls for increased protein and fat intake, according to a review published in August 2013 in the European Journal of Clinical Nutrition. Roughly speaking, on keto you’ll get 70 to 80 percent of your calories from fat, about 20 percent from protein, and as little as 5 percent from carbs.

Those issues can be part of what's known as the “keto flu,” Warren says. Other side effects of the keto diet, all of which are tied to carb withdrawal, can include lightheadedness, nausea, mental fog, cramps, and headaches, in addition to tiredness. Luckily, the keto flu doesn't usually last more than a week—which is coincidentally about when people start to see the number on the scale go down, says Warren.

Great post!! I’m a 41 year old Master CrossFit athlete, been in keto / LCHF Primal lifestyle for the past 9 years. I feel that my performance has improved a lot and continues to improve pretty significantly. I was a top 200 Master Open Qualifier on 2016 and 2017 and I’m usually on the podium of local competitions so my performance is really not bad…and I’m totally fat adapted. I follow sort of a TKD where I sometimes eat carbs at night during the week, but never above 100g so It doesn’t even kick me out of ketosis due to activity level. I’ve been playing with some measurements and I noticed that my BG reading after high intensity training sessions is really high (up to 180mg/dl). But it goes down fast (sometimes it goes down to 50mg/dl but I show no side effect of hypo, function completely normal). From my research, the high glucose post high intensity is normal and due to the stressful response of the exercise and also because my liver is producing the glucose from gluconeogeneses to provide it for the workouts, when needed. This only happens when the workouts are long, above 30 minutes.

I’ve been experimenting with MCT Oil Brain Octane. I have one questions. I’ve been eating about 20 – 25 gr. of carbs per day on a high fat, medium protein diet. I’m measuring ketones in the morning before taking the MCT and after. I’ve been taking btw. 1-2 tbsp of MCT Brain Octane with butter (Bulletproof coffee) – I measure again after 30 min., 1hr, 2 hrs. and don’t see a raise in my blood ketones. Anything I’m missing, would love to hear your thoughts, Ben. – Thx I’m measuring with Precision Xtra and Ketonix Red.
Infants and patients fed via a gastrostomy tube can also be given a ketogenic diet. Parents make up a prescribed powdered formula, such as KetoCal, into a liquid feed.[19] Gastrostomy feeding avoids any issues with palatability, and bottle-fed infants readily accept the ketogenic formula.[31] Some studies have found this liquid feed to be more efficacious and associated with lower total cholesterol than a solid ketogenic diet.[18] KetoCal is a nutritionally complete food containing milk protein and is supplemented with amino acids, fat, carbohydrate, vitamins, minerals and trace elements. It is used to administer the 4:1 ratio classic ketogenic diet in children over one year. The formula is available in both 3:1 and 4:1 ratios, either unflavoured or in an artificially sweetened vanilla flavour and is suitable for tube or oral feeding.[51] Other formula products include KetoVolve[52] and Ketonia.[53] Alternatively, a liquid ketogenic diet may be produced by combining Ross Carbohydrate Free soy formula with Microlipid and Polycose.[53]
Nutritional ketosis is a natural metabolic state in which your body adapts to burning fat rather than carbohydrates as its primary fuel. It is clinically proven to directly reduce blood sugar (as measured by HbA1c), improve insulin sensitivity (as measured by HOMA-IR) and reduce inflammation (as measured by white blood cell count and CRP). Nutritional ketosis can be induced by following a ketogenic diet. Learn more in our FAQ below!
