If he said that he's wrong. All that's necessary for ketosis is the absence of glucose and depleted liver glycogen. It's normal to go in and out of ketosis; it's certainly not an ordeal you need to recover from. The liver can only hold a limited amount of glycogen -- you would die in the meantime if it took 7 to 14 days to enter ketosis.
"As most of you reading this know, if one restricts carbohydrate intake, typically to less than about 20-50 gm/day (dependent on timing and carbohydrate composition), and maintains modest but not high protein intake (because protein is gluconeogenic – i.e., protein in excess will be converted to glycogen by the liver), one can induce a state referred to as “nutritional ketosis”"
Ketosis – advantaged or misunderstood state? (Part I)
Peter Attia put together a series of blog posts on Ketosis if anyone is interested the science.
I remember listening to an interview where he (Phinney) discusses the nutritional ketosis and carb ratio and on a panel in at a Keto conference. He also cycles regularly with some distance(I forget. . . .40 or 50 miles at a clip). I wonder if Attia and Phinney are just looking at it from different perspectives. I have read and listened to Attia discuss his ultra work and I thought he was moving away from carb restriction, then again, I could be completely wrong.

This is not true for everyone, that they eat less on keto. Some people also manage to maintain or gain on keto -- it's supposed to be a lifestyle, not a diet, after all.
I think keto works great for some people. Not everyone struggles with hunger (at least not physical hunger) or cravings, though, or wants their appetite to go away. And in that I've seen people fail on keto, it doesn't work for everyone.
I love fat and protein (and veggies cooked in fat), so I am pretty sure that after an adjustment period I could overeat on keto as easily as with any other eating style. I also believe that I feel better eating a more balanced diet with a good mix of less processed carbs (and some carb and fat based treats, sure), so that works for me.
I think people who enjoy keto should do what works for them and those who want to try it should. I only ever comment when people insist it works for everyone or that it's a superior approach in general or that it means that calories don't matter.
Off course you can gain on keto... Actually, I'm in bulk phase.
And I've lose the most part of my fat on a standard hypocaloric diet (14kg).
That's why I know how I felt during calories restriction during a high carb diet and during a high fat diet. It is quite simpler to limit food intake if you don't feel hungry.
Then there are other things to consider... But the point is simple: you cannot choose keto if you enjoy eating foods that are not compatible with it.
Any food is compatible with keto in the right quantity.
No not really, because of the strict upper limit on carbs, choosing to eat one thing that's higher in carbs would necessarily come at the detriment of stuff like veggies. Unless you're gonna call "half a slice of pizza and the rest of your day has to be entirely meat and fats so you're not over your carbs" compatible.
Most people can stay in ketosis somewhere in the range of under 50-100 grams depending on activity levels. Sedentary under 50 and higher for more active. The amount of a carb based 'treat' food needed for a fix is pretty small when you are not regularly eating starch and sugar in quantity. In the past I ate huge portions, so this is a noticeable change in my habits.
It is kind of alien to me how you are elevating vegetables nutritionally over fats and proteins. Fats an proteins are the essential macronutrients and contain all the micronutrients required. You can build a nutritional diet with minimal carbohydrates.

Very low-carbohydrate ketogenic diet (VLCKD)
•
Carbohydrate, 20–50 g/d or <10% of the 2000 kcal/d diet, whether or not ketosis occurs. Derived from levels of carbohydrate required to induce ketosis in most people.
For the active athlete, the best quick find - http://eatingacademy.com/sports-and-nutrition/ketones-carbohydrates-can-co-exist
What did this amount to?I
Fat – 351 gm, or 3,160 kcal of fat
Protein – 245 gm, or 980 kcal of protein
Carbohydrate – 321 gm, or 1,284 kcal of carbohydrate
(I used package information and Nutritionist Pro software to calculate this.)
Hence, on this day I consumed about 5,400 kcal in total at the following ratio:
Fat – 58%
Protein – 18%
Carbohydrate – 24%
By all conventional wisdom I should not have been in ketosis the next morning, right?
The following morning, my BHB level was 2.2 mM and blood glucose was 5.1 mM.
Ah, now I'm seeing some disparity. It has more to with activity then it does with consumption. Makes sense if someone is active and consuming over 5,000 calories that they'd need to consume at a ratio as stated above. I wonder if they differentiate between good versus bad saturated fat or if they just get in as much as possible? I recognize in MFPland using good and bad is not viewed favorably unless referencing a Clint Eastwood movie.

I'm curious about the mechanics but I don't believe it's healthy for everyone. I actually asked about it lately trying to think of ways to give a better carb leeway without going out of ketosis, because I know a relative who has become very mentally unstable on it, obsessing about every single food, refusing to eat cold cuts because she doesn't know the carb content and taking care not to drink more than 1-3 cups of coffee a day because she could "use those carbs" (apparently each cup of coffee has 1 gram of carbs). This is her 5th month in and she has fallen into deep depression. I admit it's just a tool and may not be the cause of her instability, but it's just obvious that's not a good approach to weight loss for her.
She was not like that when she was counting calories. She says that with calories you can generally estimate something every once in a while, slip up without consequences that take too long to fix, and just tighten or relax your calories whenever you want. With keto this is not the case because it's a very delicate balance and anything has the ability to throw you out of ketosis. Why anyone would put themselves through something that isn't working for them just because you lose slightly more on it is just beyond me.
I Learned my lesson right away when I tried it two years ago and quit after a month of erratic blood sugar, IBS coming back, weakness, extreme hunger, and general suckiness of the food choices to me.
My take: try it for a month. Some people thrive on it and you might be one of them. If you find yourself having a hard time there is absolutely no need to drag it on any further and ANY diet that induces a deficit will help you lose weight no matter what it is, so you have a world of choices to pick from.
One more thing, if you do decide to go on it make sure to get a good multi vitamin and a good electrolyte replacement, because messing with electrolytes can be scary and may cause death in some people. Also remember you might become a little bit more prone to infections so just keep a general eye on your health. Complications are rare but worth mentioning.

So this says that even at less than 50 grams you might not get into ketosis. You said below 50-100 is good.For example, a very low-carbohydrate ketogenic diet (VLCKD) is defined as comprised of 20 to 50 g/d carbohydrate, but because of individual variability, ketosis (blood ketone bodies >0.5 mM) may not occur.
Second link, alright. But obviously that's n=1, 1 day, and he titled the paragraph you quoted "Extreme example".0 -

That's a two week study. I'm talking long term. Sorry for the confusion.
Don't understand. The nutrient content of a diet isn't a function of how long you eat it for.0 -

No measurement of ketosis that I can see. They speculate that ketosis is avoided by the dietary ratios, but offer no data. At 65g of carbohydrate, moderate protein and calorie restriction I wouldn't bet either way.
So what if they ate vegetables ? {edit - I see now the claim that only fat and protein was needed for complete nutrition}
LOL.We conclude, therefore, that the low carbohydrate diet presents no health hazard, either generally or in regard to its nutritional value. The nutrient content is appreciably higher than could be achieved by a diet in which the same caloric reduction was effected by a general restriction in all foods.0 -

It matters that they ate vegetables because Umayster said you can get enough of all micronutrients entirely from proteins and fats.
Also obviously that would be the conclusion if they think you'd eat less vegetable on a "general restriction in all foods".0 -
False. Calorie deficit empties adipocytes, regardless of macro ratio. The only reason people seem to think keto diets burn more fat is because there's a mental disconnect where they don't pay attention to the fact that they are consuming such a high level of fat, which the body digests before turning to fat stores. With a 2000 calorie TDEE (for example) eating 1500 calories worth of carbs or eating 1500 calories worth of fat would both result in exactly 500 calories of stored fat burned to make up the deficit. Honestly, the carbs might even burn a bit more, as TEF for carbs is between 10 and 15%, while TEF for fat is only 2-3%.This diet sounds soooooooo hard and not quick and convenient
If you mean "quick to empty adipocytes", it is the quicker diet I think. It is the only dietary approach that turns your body into a fat-burning machine (most part of enrgy will come from fat), forming ketones from fatty acids and using them instead of glucose (there remains cells that still need glucose, but all the muscolar works and up to 70% of brain energy can come from ketones).

Mine are:
Protein 40%
Fat 46%
Carbs 14%
That works out to protein 101g, fat 51g, carbs 35g on 1003 calories per day. Granted, those numbers were decided upon by my doctor, but I plan to keep the same basic breakdown once he's done with me, just up my calories to an un-psychotic level! I'll lower carbs slightly, as he has me at 35g a day and I prefer closer to 15g, and raise my protein, which will put fat and protein about even.
Someone said that going in and out of ketosis isn't a big deal. It isn't for some, but it can be for others. It's a big deal for me, but the effects are based on each individual. My bf went from 150g to 30g of carbs in a week without a single hiccup. I dislike her greatly for this! I love this diet and it's really working well for me. Keto isn't for everyone. Like everything else diet, something that works for me may not work for you. Good luck!0 -

Here is another extreme - this example is nutritional details on a meat only eater. Vegetarians are the other extreme of food restriction and getting proper nutrients takes high levels of education, work and attention.

This guys all meat nutrition probably beats many mfp diary's, meat is nutritionally dense and complete. All you have to do is use a complete nutrition calculator like the one at nutritiondata.self.com which show all the nutrient. The following lamb example is 3 little ounces.
http://nutritiondata.self.com/facts/lamb-veal-and-game-products/4669/2
I felt like you were playing me asking for citations, isn't it obvious that you can make a nutritionally complete diet out of a wide variety of food choices? In my reading on nutrition it seems like many extreme examples of food limitation in different groups from around the world can be made to work nutritionally.0 -

It does seem very weird at first look, but you are changing your diet from running on glucose from carbs to running on ketones from fats - so the fats are your energy. Proteins have a specific use and you don't need an excess (except the bodybuilders use manipulations in protein levels)

I admit it's just a tool and may not be the cause of her instability, but it's just obvious that's not a good approach to weight loss for her.
She was not like that when she was counting calories. She says that with calories you can generally estimate something every once in a while, slip up without consequences that take too long to fix, and just tighten or relax your calories whenever you want. With keto this is not the case because it's a very delicate balance and anything has the ability to throw you out of ketosis. Why anyone would put themselves through something that isn't working for them just because you lose slightly more on it is just beyond me.
I Learned my lesson right away when I tried it two years ago and quit after a month of erratic blood sugar, IBS coming back, weakness, extreme hunger, and general suckiness of the food choices to me.
My take: try it for a month. Some people thrive on it and you might be one of them. If you find yourself having a hard time there is absolutely no need to drag it on any further and ANY diet that induces a deficit will help you lose weight no matter what it is, so you have a world of choices to pick from.
One more thing, if you do decide to go on it make sure to get a good multi vitamin and a good electrolyte replacement, because messing with electrolytes can be scary and may cause death in some people. Also remember you might become a little bit more prone to infections so just keep a general eye on your health. Complications are rare but worth mentioning.

Your post is very interesting. Possibly for your aunt with mood issues, maybe controlling diet gives her some satisfaction when her moods are out of control? Also, sodium needs double on low carb and low sodium effects can be very negative - it may be worth investigating with her.
Be careful with using epilepsy ketogenic diet studies for information to apply to food based ketogenic diet with generally healthy people unless you can see what they were feeding them and the health of the people on them. Some of the medical ketogenic diets were based on using oils to replace foods. Also ketogenic medical diets were generally reserved for those who did not respond to drugs for epilepsy, so the toughest cases.
Also, old school epilepsy ketogenic diet goals are to stop seizures, not really for long term nutrition - newer epilepsy keto diets & studies may be more relevant to normal keto, but with dist research you always have to keep the perspective of the researcher in mind. eg athletic vs normal vs medical nutrition.0 -
From one of Juimmy Moore's blogs or posts:
As you can see, within four days I was in nutritional ketosis (Volek and Phinney says it can take as much as two weeks to become fully keto-adapted) and I’ve stayed at 1.2 millimolar and above ever since averaging around 2.0 millimolar daily. While I started at an anemically low level, you’ll notice my blood ketones got as high as 5.0 millimolar at around the two-week mark. I gave blood on Day 2 of this experiment which may or may not have made an impact on the numbers. Honestly, I don’t know why the ketones went that high. And I didn’t “feel” any different with the blood levels of ketones above 3.0.
He goes on to discuss eating carbs at 1-3% of intake which is extreme in order to get back to nutritional ketosis. I do not think Volek or Phinney recommend this; as for Attia it seems he consumes larger quantities of carbs and then has a long workout to burn the carbs off. IDK, seems like Attia is an extreme example of someone who admits to not staying in ketosis and it seems Moore went very low for his carb intake, and Phinney/Volek seem to be accurate that it takes 7-14 days to get back to ketosis when you consume 50g of carbs or more.
I think the vast majority of people attempting keto would say they do not go as low as Moore and certainly do not work out to the level of Attia.
I'll post the Attia example from the begnning of 2014 and he does state not eating or training like him due to genetics and a few other attributes.0 -
From Attia's blog What I actually eat Part 3:
He asked, “How are you able to stay in ketosis with all of those carbs?” I responded, basically, that for the past few months I have not been consistently in ketosis, and when I am it’s only following a long bike ride where my BHB levels may get back into the 2-3 mM range. Most days, however, I live in the 0.3 to 0.8 mM range, depending on the time of day. (In my mind, to reap the benefits of nutritional ketosis, one probably needs to consistently be in the 1-3 mM range, and for some “applications” 3-4 mM is probably ideal.)
It seems Attia can move in and out of ketosis with greater ease due to intense workout sessions. Extremely rare for someone to work the way he does physically. It is sort of funny reading how he perceives being sedentary and eating 3,800 calories for maintenance. Again, the physical workouts are the difference maker for his caloric needs and openly states he does not stay in ketosis.0 -
Someone said that going in and out of ketosis isn't a big deal. It isn't for some, but it can be for others.
I'm in at least light ketosis more often than not but I "knock myself out" on a fairly regular basis by eating 20g-40g of carbs in a single meal but that's short lived and I'm often back in ketosis before the day is out or by morning if it was dinner. When I actually eat high carb (and not just highish carb for one meal) it's the exact same process, it just takes a few days instead of a few hours.
Like a lot of people I eat low carb for reasons beyond weight loss so I'll often speed up the process of getting back into ketosis by fasting and/or exercising intensely to get back to feeling "normal" -- that ketosis provides and the reason I choose to eat this way.
So I can easily see that if ketosis is negating an underlying pathology, if there's addictive behaviors around carbohydrate or perhaps if there's a food intolerance that's eliminated by a low carb diet it might be a very big deal to the individual. But the process of ketosis itself (in my experience and everything I've read about it) is predictable and straight forward once your body is producing the necessary enzymes.
ETA: I've also been eating this way for at least 3 years which may make a difference? I don't know.0 -
Like any diet, I think it depends on how you approach it. My meals today were as easy as it gets:
-2 eggs, coffee with coconut cream and a protein powder
-another coffee
-leftover hamburger patty, a babybel cheese, a cucumber
-spinach and feta chicken sausage and broccoli in cheese sauce
-nuts and coconut for a snack
Thanks for that. You must have a very strong willpower to stick to no carbs. I dont know if I could be that strong but for health reasons I am trying to limit my carbs to the very minimum now. Wouldn't it cost more in food? Wheat is cheaper than meat or other proteins.

@AlabasterVerve I envy your easy moves in and out of ketosis. They're awful for me. I think my keto cut-off is around 35g. I don't know, as I had WLS that causes malabsorption, so I don't know how many I'm getting. I could be getting them all, I could be getting 5g. I was happily below 20g, but that's now my minimum with my docs playing with my numbers.
I do have carb/sugar addictive behaviors, but I have a mental trick/game I can use that helps me get back down when I go over. I did that 2 weeks ago for my birthday and I don't think I'll do that again. It was a rough couple of days afterwards! I don't know if the addictive behavior makes in/out of ketosis worse and I guess in the end it doesn't matter. I have macro numbers, my mental trick, and a good support system. I got this! Feels good to say that too.
As with any diet, as I lose weight and am able to exercise more, I'm sure the ratios will change. It's a new learning experience every day! I really enjoy keto and I'll stay here even after my doctor is finished with me. I've been at it for 10 months now and it's only getting easier with time.0 -
How do people here know they are in ketosis? Can you feel the difference? Or testing for the presence of ketones? (Again, just curious.)0

Most people test and some people can feel it. I can feel it when I'm out. I'm actually jittery, sweating, headache, some physical pain. It feels like the flu. The tests just confirm what my body tells me already. When I'm in, I feel great and have lots of energy. I don't feel that way when I'm out.0 -

In the beginning, I used a glucose/ketone meter and tested my blood using (really expensive) ketone strips out of curiosity. Now it's just knowing myself -- an energetic, slightly buzzed/high feeling and I know I'm in deep ketosis, if I'm feeling normal I know I'm producing ketones and I'm in light ketosis.
If my appetite is insatiable and I feel like eating and eating some more regardless of hunger I know I'm completely out of ketosis -- even if I haven't "cheated". I flirt with the upper range of what I can tolerate carb wise and too much fruit, nuts or something similar too many days in a row is all it takes.
@2Poufs You're doing amazing.
It's such a great feeling when the pieces of the puzzle start to come together. I wish you continued success.

The only way to measure accurately costs $$ for a meter. Ketosis is a blood range value for ketones - human defined - and for me not so important as the effects of carb restriction which are easy and free to know.
Folks use the 20gr number to eat to because at that level most everyone is consistently in ketosis.
Even for those near but not in ketosis, the health benefits for metabolic issues is there - the body is making and using some ketones. This probably needs a lot more studies!
My net carbs are mostly between 15-50 and I honestly don't know about ketosis levels. I do know that even on calorie restriction, my energy levels and brain function are far more even and the horrible daily carb comas that I struggled to function through are gone.0 -

ooh, I forgot about THAT! Lack of 'eat food' thoughts is the single biggest benefit to my weight loss success. It's 2pm here and other than full cream in coffee this morning, I just started thinking about eating.
I'll shut up now!0 -
Yeah, the "not hungry" thing is quite a bonus. I did a protein shake at 1p and pre-logged lamb for dinner, but I'm still not hungry. Most days, I'm eating because not eating at all isn't an option. It's food. It's just that thing I have to do because science and doctors and stuff. And things.

I can't eat wheat so it wasn't a big loss. To be honest, the idea of going low carb was much more daunting than actually doing it. I had a week or so where I felt a bit tired, and had a headache for a few days, but now I don't miss carbs at all so no willpower is really needed. It was much harder when I was still eating more carbs (starches and sugars).0 -

I test and I can feel it. There's a boost in energy and a mental clarity that I experience. At first I thought it was just a placebo effect but my husband has noticed the difference too... Nice but a bit scary too (that my previous diet was affecting me mentally).0
