How it’s done: Warm up the LEVL or Ketonix meter by plugging it in. Blow into it and wait for the flashing light indicating it’s reading your acetone levels. The software or the color and speed of the flashing light would tell your reading: green for least acetone, red for most acetone, less flashing for less acetone per color, more flashing for more acetone per color.
Fat is the cornerstone of the keto diet, making up the bulk of calories. An individual consuming 2,000 calories per day would need to consume 144 to 177 grams of fat. Fats make up 70-80% of your calories. Since fat is the main source of nutrition on a ketogenic diet, it’s important to source high-quality, healthy fats, which you’ll read about below.

Excellent post. I am of the “everything in moderation” crowd and I have been looking at some of the ketosis ideas and part of me thought… maybe. But after reading this I feel yes, keep with your current course. There’s no reason to get all stressed about eating again! Your attitude will help others find the right path for them and happy is healthy!
But while carbohydrates can help you have a better workout, go faster, or go longer, this only applies to acute, in-the-moment performance. Once you take a look (which you’re about to do) at the long-term effects of chronic high blood sugar levels, things change drastically. If the damage that you’re above to discover is worth it to you, then you are either mildly masochistic or you value performance much more than health.

In the mid-1990s, Hollywood producer Jim Abrahams, whose son's severe epilepsy was effectively controlled by the diet, created the Charlie Foundation to promote it. Publicity included an appearance on NBC's Dateline programme and ...First Do No Harm (1997), a made-for-television film starring Meryl Streep. The foundation sponsored a multicentre research study, the results of which—announced in 1996—marked the beginning of renewed scientific interest in the diet.[1]


THANK YOU! I’ve been doing Keto for 3 weeks and I don’t think this is the diet nor lifestyle for me. I’ve been having on and off Keto Flu that included painful headaches and constant bowel issues. I thought it would be over by the end of week 1, but I continued so I thought again at the end of week 2, but continued. It’s the end of week 3 and I’m not seeing any changes. I’m feeling just as tired if not more than when I wasn’t on Keto. My mood has been more snappy and aggressive than when I wasn’t on Keto. I just wasn’t happy. I already was super sensitive to salt & salty foods and now I’m even MORE sick of salt & salty foods. I missed my fruits and veggies like carrots which my pup & I often snacked on. I got super gassy and burped more these past 3 weeks than my entire life. My period was a mess and came 4 days earlier than normal and I haven’t had an odd period in over a year after getting diagnosed with mild PCOS. Attempting Keto really threw my body in for a loop and it’s been down hill ever since. I haven’t dropped in weight, the inches are still there, the bloating is still there. But now I have this fear of eating. I used to miss meals before and did IF for a while but now I miss even MORE meals and rarely eat which is just a recipe for weight gain when you’re consuming high fat. I’ve stocked my fridge with items I rarely ever bought: Sour Cream, Bacon, Cream Cheese, Heavy Whipping Cream. All because I needed to hit my fat macros.
Before starting, ask yourself what is really realistic for you, Mattinson suggests. Then get your doctor’s okay. You may also work with a local registered dietitian nutritionist to limit potential nutrient deficiencies and talk about vitamin supplementation, as you won’t be eating whole grains, dairy, or fruit, and will eliminate many veggies. “A diet that eliminates entire food groups is a red flag to me. This isn’t something to take lightly or dive into headfirst with no medical supervision,” she says.

It is interesting to note that the KB are capable of producing more energy than glucose due to the changes in mitochondrial ATP production induced by KB (Kashiwaya et al., 1994; Sato et al., 1995; Veech, 2004). During fasting or KD glycaemia, though reduced, remains within physiological levels (Seyfried and Mukherjee, 2005; Paoli et al., 2011). This euglycemic response to extreme conditions comes from two main sources: glucogenic amino acids and glycerol liberated via lysis from triglycerides (Vazquez and Kazi, 1994; Veldhorst et al., 2009). Glucogenic amino acids (neoglucogenesis from amino acids) are more important during the earlier phases of KD, while the glycerol becomes fundamental as the days go by. Thus, the glucose derived from glycerol (released from triglyceride hydrolysis) rises from 16% during a KD to 60% after a few days of complete fasting (Vazquez and Kazi, 1994). According to Bortz (1972) 38% of the new glucose formed from protein and glycerol is derived from glycerol in the lean while 79% in the obese (Bortz et al., 1972). It is important to note that during physiological ketosis (fast or very low calorie ketogenic diets) ketonemia reaches maximum levels of 7–8 mmol/L with no change in blood pH, while in uncontrolled diabetic ketoacidosis blood concentration of KBs can exceed 20 mmol/L with a consequent lowering of blood pH (Robinson and Williamson, 1980; Cahill, 2006) (Table ​(Table11).


In its 2016 report “Healthy Eating Guidelines & Weight Loss Advice,” the Public Health Collaboration, a U.K. nonprofit, evaluated evidence on low-carbohydrate, high-fat diets. (The Keto diet falls under the LCHF umbrella.) Among 53 randomized clinical trials comparing LCHF diets to calorie-counting, low-fat diets, a majority of studies showed greater weight loss for the Keto-type diets, along with more beneficial health outcomes. The collaboration recommends weight-loss guidelines that include a low-carbohydrate, high-fat diet of real (rather than processed) foods as an acceptable, effective and safe approach.
I originally started this “diet” because I am the Maid of Honor in my best friends wedding. She made me order a size down than I was comfortable with and it fit, if you didn’t zip it up. I tried it on a couple weeks later and it REALLY didn’t fit, I couldn’t pull it up past my hips. I was mortified and super embarrassed, how was I going to be in this wedding if I can’t even fit in this dress. Cut to now, I just tried on my dress and it’s too big! I’m so excited that I have to get it altered.
If you give your body any more than the absolute minimum amount of protein that it needs, it will immediately break it down into carbs. This is why keto sites often give a guideline for not eating too much protein. The problem is that there’s no one guideline that works for everyone, and without specifically tailoring keto to your body it’d be easy to accidentally ingest too much protein.

Between the butter and the so-called “Brain Octane Oil” that are part of the Bulletproof coffee recipe, any increased energy one feels after consuming it could have something to do with the nearly 500 calories of fat that are in it. As has been pointed out, those calories displace other more nutrient-dense sources of fuel. Asprey also claims that his coffee is better for you because it doesn’t contain mycotoxins, i.e. toxins produced by fungi. Though it’s true that mycotoxins can be dangerous for your health, the possibility of any roasted coffee available on store shelves containing mycotoxins is slim to none. It’s like slapping “this coffee was not made with white rhino horn” on the label.
“For events longer than 60 minutes, consuming 0.7 g carbohydrates·kg-1 body weight·h-1 (approximately 30-60 g·h-1) has been shown unequivocally to extend endurance performance. Consuming carbohydrates during exercise is even more important in situations when athletes have not carbohydrate-loaded, not consumed pre-exercise meals, or restricted energy intake for weight loss. Carbohydrate intake should begin shortly after the onset of activity; [and continue] at 15- to 20-min intervals throughout the activity.”
"Made from coconut milk (which is high in fat and low in carbohydrates), dairy-free coconut yogurt can be an enjoyable treat to curb sweet cravings and promote satiation," Ruani told INSIDER. Opt for sugar-free or unsweetened versions, she advised, or try making your own by blending full-fat coconut milk, probiotic cultures, and a bit of stevia for a sweet touch.
Move more. You’ll lose pounds faster if you increase your daily physical activity. Keep in mind you don’t have to go to the gym 6 times a week or jog every morning, just move more in your everyday life. For instance, take a short 2-minute break from sitting in your chair every hour, take the stairs instead of the elevator, walk to make errands if you can, get a standing desk, or take phone calls standing up and pacing around. These small calorie-burning movements add up at the end of the day.
Whilst the diet is broadly acknowledged to be safe strategy where medications have failed, side effects such as kidney stones, hyperlipidemia and can occur47. Furthermore, maintaining dietary adherence in young school age children can be very challenging for caregivers. Exogenous ketones may be an alternative or a adjunct to the ketogenic diet in epilepsy. Early work suggests that exogenous ketones could have antiseizure effects. Injection of the ketones acetoacetate and acetone have been found to have anticonvulsant properties in animal models48, and an acetoacetate diester was found to protect against seizures in rats exposed to high levels of oxygen49. Further studies are required to understand specifically how ketone bodies affect seizure control, however for children who experience daily seizures a combination of the ketogenic diet and exogenous ketones could be helpful to manage their condition.    

Day 5: As fate would have it, 3 p.m. rolls around and we get a message that there are cookies in the conference room. I have been snacking on keto-approved foods like Granny Smith apples (the tart green apple has way less sugar than, say, a red Gala), and full-fat cottage cheese with blueberries (where have you been all my life, snack?) with no real trouble with cravings. But just knowing there are cookies that I can't eat makes me feel a little cheated.  (Though These Low-Carb Keto Desserts Help With That.)

I’m missing one key-step in this whole process … I understand (vaguely) how to get into ketosis via diet, starvation, or supplementation. But, my confusion really is with the supplementation method (such as XCT Oil, for example). If I supplement with these to get into ketosis quicker, but haven’t significantly altered to a high-fat diet, won’t I just shift back into glucose-use as soon as I burn out the supplemented ketones?? like within minutes / hours?
So, the other day I bought some broccoli and I was staring at the stems thinking "I know I can do something besides just slice and sauté these (I am aware that people rice them, but now that bagged frozen riced cauliflower is a thing I will never rice anything again) I pulled out my mandolin and sliced them up figuring i could ten sauté or do something else, and then realized that they were the perfect "Chip" size! First I ate some raw with labne (yogurt cheese) Delicious! Very good option for when you want to dip something! Then today decided to try frying them...
This was a great post. I did Keto last year, really strictly, and dropped 13 lbs in about 3 weeks. Then the holidays came and I had cookies. I’ve struggled since then to get back into the Keto mode. I do well for a few days, drop a few lbs and then have a “bad” weekend and back up I am. I’ve literally been gaining and dropping the same 5 lbs. for a year. I also miss certain carbs. I love bread and homemade bread can be healthy. I miss yams and beans, etc. I’m beating myself up because I want these foods I’ve eaten my entire life and now “can’t”. I appreciate your comments about accepting and loving our bodies no matter what size. Yes, I want to be healthy but I’m tired of obsessing about every single thing that I put in my mouth. This article is inspiring.
Some people do not produce enough ketones to show up in their urine. If you are experiencing a reduction in your appetite and an improvement in well-being and are losing weight or your clothes are feeling looser, there is no need to do anything differently. Remember, the lipolysis testing strips (LTS) are tools; making them change color is not the sole object of the game. If you are not losing weight, you either have a strong metabolic resistance to weight loss or you are consuming "hidden" carbohydrates in the form of sweetened salad dressing, breading, etc. Then follow Induction strictly for five days. If the LTS still haven�t changed even slightly, make sure you are not consuming excess protein and measure your salads to make sure you are not eating too many veggies. Still no change? Try cutting out tomatoes and onions, which are relatively high on the glycemic index. You may also benefit from nutritional supplements such as L-carnitine, hydroxycitric acid (HCA), and chromium - all of which aid in hunger reduction or weight loss. You may also need to step up the frequency and intensity of your exercise program.
I have never weighed myself after I started Keto though, I started out at 120kg and my goal was to hit 80kg eventually with no deadline. However, I was worried that if I hit it eventually, I would be less motivated to continue this lifestyle so yeah I have no idea what’s my weight now. I do know my waist has gone from 46” to 36” when I went to get new clothes.
"Mushrooms are mostly made of protein, fiber, and water, making them very filling," said Alex Ruani, nutrition science educator at The Health Sciences Academy. Low-starch foods like mushrooms are unlikely to kick you out of ketosis, she suggested, making them an ideal staple during low-carb eating. To add mushrooms to your diet, she recommended stirring them with scrambled eggs. Doing so makes a delicious and very filling low-carb meal, she explained.

Ketone ester drinks can improve performance30. When taken with pre-exercise carbohydrates, a BHB-butanediol (BHB-BD) ketone ester allowed cyclists to ride 2-3% further in a 30 minute time trial than with carbohydrate alone. This is likely to be a combination effect of: Ketones themselves being a highly efficient fuel and improving muscle efficiency. Fuel availability is a key determinant of performance. By increasing the availability of an alternative fuel (ketones) during exercise this spares muscle carbohydrate stores for later in the exercise bout meaning more is available for the end of the test. 

I’ve been on Keto for o ver a year now and I am delighted about how I look and feel. I’m 71 years old and I have more energy now and no pain for the first time in such a long time. I lost 35 lbs in about 4 months and have kept it off with no trouble. I do follow it pretty strict but not afraid to eat a few no nos. My husband of 51 yrs passed away and I’m alone to take care of a 40 acre farm. Friends and neighbors are amazed at the work I am able to do. In fact they’re asking me about the Keto diet. I do hard labor on my farm and 2 days a week I do weight exercise. My blood sugar and trygicerides are low and soon will be off high blood pressure meds soon. Everyone says how great I look.

You indicate that exogenous ketones do not shut down the ability, of your body, to oxidize fat. Is that to say it does not have an effect on your body at all? My specific question is… does my body oxidize less fat, when supplementing with exogenous ketones? I think you indicate in your article that it could. I would expect it to, in that if I supplement then my body would not “need” to oxidize the fat to provide the energy.

The carbohydrate–insulin model predicts that the KD would lead to increased EE, thereby resulting in a metabolic advantage amounting to ~300–600 kcal/d. Our data do not support EE increases of that magnitude. (...) In summary, we found that a carefully controlled isocaloric KD coincided with small increases in EE that waned over time. Despite rapid, substantial, and persistent reductions in daily insulin secretion and RQ after introducing the KD, we observed a slowing of body fat loss.

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?
Well I've been doing Keto for almost 3 months now and I feel great. I have more energy than I've add in a long time and I'm becoming more of a morning person now LOL. I feel so much better about how I look now and I've actually wanted to dress nice for work, actually tucking in my polo now instead of just leaving it out. Last couple of weeks I've been teetering between 200 and 205 lbs. SOOOOO close to Onederland. Just gotta keep at it and KCCO. I've been inspired by all the progress pics posted here so hopefully my 3 month pics can inspire some of you!!!!. Keep at it ya'll and remember the NSVs are sooooo much more important than what the scale says.
At the beginning of the year I was counting calories, I was losing weight but I was eating the same thing....every day....never deviating. I lasted 4 months. The lowest I ever hit was 325, starting from 347. I mean that is not bad, and I was losing weight, but I was so bored with my food. Since starting Keto, I am already down to 328 IN TWO WEEKS. I am shocked. I had to have my wife hide the scale, because I kept standing on it not believing what I was seeing. I am eating so well right now.
On Cyclical keto, I noticed these weird bouts of depression every time I carbed up on the weekends. I saw this study and they were linking inflammation to depression and it makes sense because every time I knock myself out of ketosis, I deal with this weird depression, then a few days back into keto, my head feels more clear. Strict keto is where I feel the best. This is where I’m getting the best results. I keep my fat percentage higher, around 80 percent."
When in the hospital, glucose levels are checked several times daily and the patient is monitored for signs of symptomatic ketosis (which can be treated with a small quantity of orange juice). Lack of energy and lethargy are common but disappear within two weeks.[17] The parents attend classes over the first three full days, which cover nutrition, managing the diet, preparing meals, avoiding sugar and handling illness.[18] The level of parental education and commitment required is higher than with medication.[43]
Came across this old pic yesterday and wanted to compare it to my recently uploaded pic. This was from when I was doing an all fruit / starch vegan diet. I also consumed gluten here and there.. thank God I got tested for food sensitivities or I would be in poor health still. Nothing against the vegan diet, but everyone’s body is different. People have had success with veganism and people who are insulin resistant haven’t. So glad I found Keto thanks to @jason.wittrock 💪🏻 - - - - - - - #waronsugar #keto #ketoquest #fitness #transformationtuesday #journey #fatloss #hardwork #progress #shred #workout #fitnesswomen #fitnessmotivation #bodybuilding #weightloss #weightlossjourney
