Sorry, I guess I read your comment wrong. You are wondering what to do about sugar levels, weight, and enjoy life. Personally, I have found that eating mindfully and listening to YOUR body is your best resource. No diet can tell you what to do, only your body can do that. Do you feel good eating more carbs? Do you feel better eating less carbs? Do you feel better fasting or not? Your body will tell you what to do. Also, I want to ask, what is the reason for wanting to lose weight? Is it purely health? Have you had tests that tell you your health is bad? Sometimes we get stuck on a specific number for what we “want” to weigh, which actually has NOTHING to do with out health. I recommend the book, Health at Every Size if you want to learn more about that. All of us have a weight set point, and for some, that is higher..which may be hard to accept. If I were you, I would take the focus OFF of weight loss completely and focus on eating in a way that nourishes you and makes you feel good and happy. Life is too short to focus on what is “right” and “wrong.”
While you’re focusing on fat, protein, and carbs, you should also make sure you’re getting adequate fiber. “People often assume that they should only eat things like meat and butter on the ketogenic diet,” says Farshad Fani Marvasti, MD, an associate professor and director of Public Health, Prevention, and Health Promotion at the University of Arizona College of Medicine in Phoenix. “You should make sure you are eating enough vegetables because you need the fiber.”
Oh my god! This is one of those ‘Too-good-to-be-free’ comprehensive resources. I’ve been following your content and I wonder why you give away so much well researched info for free. Anyway, that’s a pretty damn good job you’ve done here. Until I read this, I was floundering with so much bit sized confusing information out there. You’ve literally dumbed it down for me. I’m off to take my measurements before I start the diet! Thanks a ton!!!
I have read your article and lots of other stuff on Keto, but I still don’t understand why it has to be so high in fat? I am on a calorie controlled diet which should also be pushing me into ketosis (Optifast + veges) nutritionist suggestion to go hard for a month. But after that was looking at moving to a Ketogenic diet. I am just having a hard time with understanding why it has to be high fat. Can you help me understand? Also love your writing style (particularly referencing Ace Ventura).
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.
As a matter of fact, from a pure biology perspective, lauric acid should actually be considered a LCT, because unlike C8 and C10 forms of MCT, lauric acid gets processed by your liver. This matters because your body metabolizes MCT’s differently than LCT’s: unlike LCT’s, MCT’s get very quickly converted into ketone energy to fuel your brain and body instead of requiring a pit stop in the liver for processing.
Medium-chain triglycerides, or MCTs, are a type of fat that gets digested quickly and can help ketogenic dieters boost fat intake and stay in ketosis. Studies suggest that supplementing with MCT oil can help promote weight loss and boost feelings of fullness. Hence, MCT oil can be a great weight loss tool for those following a keto diet. Read - Weight loss and crash diets: Beware, yo-yo dieting can give you belly fat - use these 6 tips to lose weight
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.

The 2017 meta-analysis by Drs. Kevin Hall and Juen Guo provide us with very convincing data, but we must also consider the fact that the data came from studies where all the food was provided by the scientists. Although this is a great way to assess the difference between low-carb and high-carb diet, this does not simulate the real-world effectiveness of each diet. For this reason, we must investigate data from less strict studies. In other words, we need to look at what happened when subjects were told to follow a specific diet on their own.

These types of back-and-forth weight fluctuations can contribute to disordered eating, Kizer says, or can worsen an already unhealthy relationship with food. “I think this diet appeals to people who have issues with portion control and with binge eating,” she says. "And in many cases, what they really need is a lifestyle coach or a professional counselor to help them get to the bottom of those issues."

Keto runs counter to many of the low-fat diet fads of the 1980s and 1990s: It actually emphasizes fat. “That is hard to comprehend because we don’t eat anything that’s pure fat, says Kristen Mancinelli, RD, author of The Ketogenic Diet. “We don’t eat a stick of butter or a spoonful of olive oil or even a nice cup of lard. That would be unpleasant, so we really have a hard time wrapping our heads around this concept of the ketogenic diet.”
If I see a TSH above 2.0 or a trend towards higher values in someone who is testing repeatedly, I get worried – and prefer to see TSH at 0.5-2.0. Of course, this doesn’t mean that you begin to shove carbohydrates indiscriminately down the hatch. However, it means that your high-fat, low-carb diet should include thyroid supporting foods rich in iodine and selenium, such as sea vegetables and brazil nuts, and should also include carbohydrates timed properly, such as before, during or after workouts, when the carbohydrate is more likely to be utilized for energy and less likely to spike blood glucose levels.
Moreover, recent studies show that the Inuit have evolved a number of rare genetic adaptations that make them especially well suited to eat large amounts of omega-3 fat.[57][58][59] And earlier studies showed that the Inuit have a very high frequency—68% to 81% in certain arctic coastal populations—of an extremely rare autosomal recessive mutation of the CPT1A gene—a key regulator of mitochondrial long-chain fatty-acid oxidation[60][61]—which results in a rare metabolic disorder known as carnitine palmitoyltransferase 1A (CPT1A) deficiency and promotes hypoketotic hypoglycemia—low levels of ketones and low blood sugar.[62] The condition presents symptoms of a fatty acid and ketogenesis disorder.[62] However, it appears highly beneficial to the Inuit[60] as it shunts free fatty acids away from liver cells to brown fat, for thermogenesis.[63][64] Thus the mutation may help the Inuit stay warm by preferentially burning fatty acids for heat in brown fat cells.[64] In addition to promoting low ketone levels, this disorder also typically results in hepatic encephalopathy (enlarged liver) and high infant mortality.[65] Inuit have been observed to have enlarged livers with an increased capacity for gluconeogenesis, and have greater capacity for excreting urea to remove ammonia, a toxic byproduct of protein breakdown.[57][66][67][68] Ethnographic texts have documented the Inuit's customary habit of snacking frequently [69] and this may well be a direct consequence of their high prevalence of the CPT1A mutation[70] as fasting, even for several hours, can be deleterious for individuals with that allele, particularly during strenuous exercise.[57][70] The high frequency of the CPT1A mutation in the Inuit therefore suggests that it is an important adaptation to their low carbohydrate diet and their extreme environment.[57][60][70]
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!

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.

Starting off with it, but with the ~ 50g carbs/day. I’ve been using MyFitnessPal to track, using some advice from ketovale and others to set the targets in the service to help. Only been doing it for ~ 10 days, but down about 8 pounds so far. My biggest problem – need more veggies in my diet and that’s a bit tougher. Working on that with salads and such. I also need to purge out the older salad dressings made w/ vegetable oils and such, but getting there. So – not fully into Keto, but working towards that. I’ve definitely found that I can eat quite a few foods I actually like so that’s not a huge downside. Do I miss pizza/pasta/tortillas? Sometimes. But there are keto pizza crusts (of a sort) and spaghetti squash works really well for me to replace pasta. I have yet to try a “zucchini” wrapped enchilada, but I think that might work as well.

Obesity means that someone has an excess amount of fat to the extent that it harms your health. Oftentimes, doctors, nurses, and other professionals will put your weight in terms of your height and gender in a figure called body mass index (BMI). According to the World Health Organization, a BMI from 25-30 usually indicates someone is overweight, BMI in the 30-35 range puts someone in the range of being obese and 35 and over morbidly obese.

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.
The biggest draw for me is how many of those who’ve tried it say they don’t get hungry. The possibility of that blows my mind, as someone who’s used to any sort of calorie restriction meaning hours of feeling hungry every day. It’s tantalizing enough that I at least want to try. And what have I got to lose, right? I’m already morbidly obese; it’s hard to imagine screwing this up so bad it makes that worse.
My goal with this blog is to help free you from the bondage that diets create. I want to help you learn to trust your body again and start loving the body you’re in. Because our worth is NOT determined by the size we are. Rather, let’s look at what type of human being we can be in this world. Compassionate, forgiving, loving, kind, generous, happy – these are the things that matter to me. These are things I want people to remember me by…not by how much I exercised or what I ate.
Fascinating stuff and I am quite curious how we know for certain one is actually in ketosis i.e. using ketones as primary fuel source BECAUSE we do know that glucose has a shorter metabolic pathway to burn and under most conditions, given the presence of glucose, that is what the body will default to which is why high fat and high sugar together in diet is so detrimental. So if we use one or more of the above “boosters” and show high levels of blood ketones but also highish levels of glucose (during initial transition) will be mostly burning ketones or still defaulting to glucose?
Hi Ben – Great article. I had trouble at the end figuring out if you were now eating high fat (60-80% of calories), or if you went back to something closer to 50% fat calories and higher carbs and are using exogenous ketones to get int ketosis when needed. Are you doing any carbs at night or a refeed, or just having higher carbs on most days? Thanks
Since the birth of my daughter 32 years ago, I have struggled with my weight. I remember when “fat free” was the only way to go. So for a year, I avoided fat like the plague and ended up with hair loss, gray dry skin and just an overall unhealthy look despite the fact I was at my healthy weight. Now we are suppose to eat massive amounts of fat according to the professionals. I have since learned that going from one of extreme to the other is not the answer and your blog has helped me to realize that I need to do what works for my body. It is as if you gave me permission to not listen to all the so called experts. I have started eating natural, If God made it I eat it. I no longer eat foods that come out of a box or that was created in a lab. I completely agree with your blog. Thanks for speaking out!
Got a salad today from Subway, and was really happy with it! I basically ordered the same sandwich I would always get but ordered it as a salad instead of a sub. Cold cut combo with all the veggies (minus jalapeño and olives) and mayo. It was great, and huge! I stuffed myself and only ate half, and hey chopped up all the meat and veggies which I wasn’t expecting. Definitely recommend!
A few variables were tested in conjunction with weight loss. One was initial insulin secretion, specifically to see if it had any affect on loss in each diet group. It did not. They had also checked a few genetic markers that were suspected to give dieters pre-dispositions to success either on low fat diets or low carb diets based on previous studies. However, genetics were shown to have no effect.
Like the ketogenic diet, the subjects aimed to eat 20 grams of carbohydrates per day or less for a 2-3 month induction phase; then, they were asked to eat 50 grams of carbohydrates daily for the following 9-10 months. All participants were instructed to maintain a calorie deficit and utilize professional support to adjust to their diet and make sure that they stayed healthy. Additionally, the research team emphasized general health-promoting behaviors such as regular exercise and using nutritional supplements.
Collagen is a type of protein that has been shown to suppress appetite[*], provide fullness compared to other proteins like whey, casein, or soy[*], help retain muscle mass[*] and even help to reduce the appearance of cellulite due to it’s ability to improve skin elasticity and thickness[*]. Refer to this article for more information on the benefits of collagen and the best way to supplement it in your diet.
