I can easily make these things keto and they don't trigger a binge & food coma like high-carb "real" cakes and ice cream.
Have you ever had a steak coma... best thing ever!!! I get one every time I go to texas de brazil or korean bbq. So much better than any crappy cake coma (which is mainly fat btw
)
When its an all you can eat, i do.. in fact i dont eat breakfast or dinner. I am getting my moneys worth.4 -

Believe me I am no stranger to a buffet.
It's just not in my goals to achieve maximum limits.
EDIT: Also, a lot of protein can have a blood sugar spike nearly similar to regular carbs. Gluconeogenesis.0 -

I am so lost as to your opinion in this thread. You have previously posted that you are anti-keto because you like fruit, especially fruits that are considered high in sugar (fructose). But, you are anti-sugar.
I'm anti added refined sugar. Sugar can't be completely avoided but we don't need to add more or consume it in a form that is rapidly absorbed. So while I will eat fruit I'll avoid fruit juice. The reason is I do believe fructose is probably too high of concentrations in juice and sugars in liquids are absorbed very quickly into the blood.
As people have pointed out, toxicity is often about the dosage. Eat an apple and over the next 90 minutes about 10 grams of fructose hit your liver. Drink a glass of apple juice and over the next few minutes 25 grams of fructose hit your liver. Probably more than a 10x difference in dosage over time.
Whole fruit has fiber and lots of other nutrients that justify the risks caused by fructose. Also some fruits are vital to me because the reduce the impact of sodium, for example a banana a day.
Generally I'm mostly avoiding processed foods that have added sugar. That is actually pretty easy to do in Japan, I think it would take a lot more work in the US.
The ketosis diets are much more restrictive. But I think the restrictions on carbs forces people to avoid adding sugar. So the diet benefits from that. I'm not really anti-ketosis, I just think it is difficult to achieve, hard to maintain and isn't necessary for weight loss.
In my mind I've have about 4 groups of foods for sugar:
AVOID 100% - sugar in liquids
Mostly AVOID - processed foods (I make an exception for peanut butter and chocolate in small amounts)
RARELY - deserts
OKAY - Foods with fiber and without added sugars.
I may play around with cutting fruit at some point, but currently my hunger is controlled and I'm losing fat so I don't see the need to do that right now.
Just to point out, Alan Aragon suggest many of the diet strategies you employ. He is one of the most unbiased people and doesnt fear monger like the likes of Dr. Lustig. What i do get a laugh about is the lustig is overweight himself. You would think that being in his position, he would be more fit.
It may be that the blog I read is atypical, we all have our issues. As for Dr. Lustig being overweight, he may well be. Dr. Atkins was also overweight, probably to a much higher degree. Being thin doesn't seem to be a requirement for talking about diet. (Just watch some of the interviews with Dr. Atkins if you don't believe that.)
I don't think there are any claims that cutting back on sugar is a magic cure, it just gets rid of a barrier that causing a lot of people issues. It still takes effort to lose weight. In my own case I only had a few spots in may diet that were high sugar. I cut them because of calories not because of sugar. After that my hunger went down which I found confusing at first. Two years ago when I was trying to lose a lot of fat I really suffered from hunger. It is in my search for why I'm not so hungry that I ran across Dr. Lutig's presentations. I really find it hard to believe that people would consider those presentations fear mongering. I guess that just shows the addictive power of sugar. I guess I'm lucky that I don't crave sugar so much.
I'm sorry but the juxtaposition of these two phrases made me smile.
he even debunked himself
https://m.youtube.com/watch?v=QQ6LhzCrPpk
That isn't debunking. That is just an attack by someone hoping to fool people. The same kind of attacks can be done to anyone.
If you listen to the long talks he explains that position. While you get fructose from eating fruit, it is at a much lower level spread out more in time and the whole fruits typically come with enough benefits to balance out the negative effects of fructose.
Also what do you say about the video I posted where he claims table sugar is somehow a carb and a fat and that there's no natural food that has carbs and fat? That's objectively a falsehood. The man doesn't know wtf he's talking about.
I have no idea, but that is a hack job video. It wasn't said in the presentations I watched.
In fact the data shows added sugar availability has gone down from a high of 26.4 teaspoons a day to 22 teaspoons a day in 2013. I'm assuming availability is basically consumption because they even show overall calories. http://www.ers.usda.gov/data-products/food-availability-(per-capita)-data-system.aspx, which by this data has from 2039 kc in 1979 to 2544 in 2013. There is lots of bouncing around in those figures and the high was in 2607 kc in 2002. These figures are per capita.
There are a lots of problems with claiming this shows sugar isn't a problem.
1) 22 teaspoons a day of ADDED sugar is still INSANELY high. It is about 4x what W.H.O. recommends.
2) While there was a decrease in added sugars, there has been a large increase in fats. (444 in 1999 to 589 in 2010.) High sugar and high fat isn't a good combination.
3) There is no accounting for time lag in the blog. Diet changes take years to be notiable across a large population.
So while the blog is very interesting and thought provoking, I don't see how one could say that proves that added sugar isn't an issue. I still think the reason there can be real positive metobolic changes on a ketosis based diet is the low added sugars. These things can't be judged by weight either, there are healthy fat people and metabolically sick thin people. I've personally know very thin diabetics, however they were also people adverse to exercise.
I wouldn't try to claim that people in ketosis don't experience profound metabolic improvements. However that isn't an ketosis only advantage either as there are many diets and approaches that accomplish that goal. That is why I personally think it is something else like added sugars that's makes the difference. It could be something else too, but there has to be a reason why radically different diet approaches work.

The who recommends up to 5% of your calories can be from added sugars. So yes, 22 tsp might be 4 times your recommendation, it isn't for everyone.stevencloser wrote: »My point has been clearly made.

And yes, there is a reason that different diet approaches work. It's called adherence and energy balance. That doesn't sell books though.4 -

Increasing food quality alone can improve health but not as much as weight loss and exercise. But for optimal health, you should do all three.
My issue with your chart is limiting high sugar fruits, rice and things like potatoes. All of those are highly nutrient dense and only need to limited by those with IR or medical issues. Applying that to everyone is meaningless.

For the life of me I can not figure out how every single post I make is somehow supposed to apply to the entire population. If MFP offered signatures I'd be happy to put in a disclaimer to avoid this confusion.- Just because I say I don't need to count calories eating a low carb diet does not mean everyone else who doesn't eat a low carb diet needs to count calories.
- Just because cake and ice cream trigger binges in a poster does not mean anyone was saying carbs trigger binges in everyone. That's absurd.
- Just because there are studies that show improved health markers eating a low carb diet (even without weight loss) that does not mean everyone experiences improved health eating a low carb diet.
- Just because some peoples diet quality improves when switching to a low carb diet does not mean that applies to everyone.
A low carb diet limits sugars and starches regardless of whether they're nutrient dense or not. Whether there's a medical need or not. It's the foundation of the diet so OF COURSE it only applies to those who choose to eat a low carb diet.9 - Just because I say I don't need to count calories eating a low carb diet does not mean everyone else who doesn't eat a low carb diet needs to count calories.

People don't need those specific sources of nutrient dense foods though. Those of us who are low carb choose other nurient dense food because they are lower carb. It is not being applied to everyone is the point here.
Rice hasn't been available to my north eastern European ancestors for more than a couple of hundred years. At most. We made due with other vegetables and meats. Rice is not bad but we don't need it.
Potatoes were thought of as food only fit for livestock until just over a couple hundred years ago. My ancestors did fine without it. Potatoes are not bad but we don't need them.
And we didn't have the high sugar fruits from the tropics. We don't need those either. Berries and some apples was probably the extent of it.
These foods you listed are not needed for good health. At all. There are so many nutritious options, that are low carb, that people on a low carb diet can choose instead. People on a higher carb diet may well choose potatoes, rice and high sugar fruits and pass up lower carb, nutrient dense foods like avocado, nuts, spinach, kale - that's their perogative.

That is the lamest reasons yet for a low carb diet. Many of the foods used in a ketosis diet are unnecessary for a healthy life. There are many different groups all over the world that eat different diets and do fine.
FACT: We don't need large amounts of protein in our diet and can get enough protein from plants.
FACT: We don't need any animal products in our foods for a healthy life.
FACT: We don't need to add fats to our foods.
Vegans on the average are probably much more healthy than almost any other group and they consist on a very high starch, low fat diet. This avoiding high carbs because they aren't needed is no different than saying avoid anything from animals because it simply isn't needed. Both are pretty lame reasons.1 -

I never said those were reasons for a low carb diet. I said we can easily, and healthfully, choose other nutrient dense foods that are lower in carbs.
I eat a ketogenic diet because I have stubborn insulin resistance that did not respond to a 20% body weight loss, did not improve with regular exercise, and does badly with a higher carb diet. I also use it to treat a few autoimmune disorders and for a feeling of overall improved health. I did not switch to a ketogenic diet so that I would have the opportunity to switch from rice to spinach.
And I never said that people on other diets would not do fine.
Your "FACTS" are relatively true but have nothing to do with a ketogenic diet.
No, we don't need large amounts of protein. I agree. A ketogenic diet is low carb high fat diet. Not high protein. And I do know of vegetarians who follow a ketogenic diet. Vegetarianism and ketogenic diets aren't exclusive of each other.
So we don't need any animal products in our food for a healthy life? I disagree with that. Without supplementation, I doubt many vegans would stay healthy over the long term.
We don't need to add fats to our foods? I like adding fats to my food. Butter on steamed veggies or a steak is wonderful. Whipped cream in coffee is tasty. Melted cheese in a egg, veggie and ground beef casseole is excellent, and eggs cooked in bacon drippings are the best. Why would I not add fat to my foods? I see no problem there.
I still think that rice, potatoes, and high sugar fruit are not needed for good health. At all.4 -

I don't agree that there isn't anything different going on with ketosis but I absolutely believe that improved diet quality eating low carb is partly responsible for the good health some people experience and the improved health markers shown in studies. Christopher Gardner even listed diet quality as a potential confounding variable on his latest study.
When you take away these foods:
You're left with a ton of nutritious foods to choose from and not much else:
Increasing food quality alone can improve health but not as much as weight loss and exercise. But for optimal health, you should do all three.
My issue with your chart is limiting high sugar fruits, rice and things like potatoes. All of those are highly nutrient dense and only need to limited by those with IR or medical issues. Applying that to everyone is meaningless.
People don't need those specific sources of nutrient dense foods though. Those of us who are low carb choose other nurient dense food because they are lower carb. It is not being applied to everyone is the point here.
Rice hasn't been available to my north eastern European ancestors for more than a couple of hundred years. At most. We made due with other vegetables and meats. Rice is not bad but we don't need it.
Potatoes were thought of as food only fit for livestock until just over a couple hundred years ago. My ancestors did fine without it. Potatoes are not bad but we don't need them.
And we didn't have the high sugar fruits from the tropics. We don't need those either. Berries and some apples was probably the extent of it.
These foods you listed are not needed for good health. At all. There are so many nutritious options, that are low carb, that people on a low carb diet can choose instead. People on a higher carb diet may well choose potatoes, rice and high sugar fruits and pass up lower carb, nutrient dense foods like avocado, nuts, spinach, kale - that's their perogative.
That is the lamest reasons yet for a low carb diet. Many of the foods used in a ketosis diet are unnecessary for a healthy life. There are many different groups all over the world that eat different diets and do fine.
FACT: We don't need large amounts of protein in our diet and can get enough protein from plants.
FACT: We don't need any animal products in our foods for a healthy life.
FACT: We don't need to add fats to our foods.
Vegans on the average are probably much more healthy than almost any other group and they consist on a very high starch, low fat diet. This avoiding high carbs because they aren't needed is no different than saying avoid anything from animals because it simply isn't needed. Both are pretty lame reasons.
I never said those were reasons for a low carb diet. I said we can easily, and healthfully, choose other nutrient dense foods that are lower in carbs.
I eat a ketogenic diet because I have stubborn insulin resistance that did not respond to a 20% body weight loss, did not improve with regular exercise, and does badly with a higher carb diet. I also use it to treat a few autoimmune disorders and for a feeling of overall improved health. I did not switch to a ketogenic diet so that I would have the opportunity to switch from rice to spinach.
And I never said that people on other diets would not do fine.
Your "FACTS" are relatively true but have nothing to do with a ketogenic diet.
No, we don't need large amounts of protein. I agree. A ketogenic diet is low carb high fat diet. Not high protein. And I do know of vegetarians who follow a ketogenic diet. Vegetarianism and ketogenic diets aren't exclusive of each other.
So we don't need any animal products in our food for a healthy life? I disagree with that. Without supplementation, I doubt many vegans would stay healthy over the long term.
We don't need to add fats to our foods? I like adding fats to my food. Butter on steamed veggies or a steak is wonderful. Whipped cream in coffee is tasty. Melted cheese in a egg, veggie and ground beef casseole is excellent, and eggs cooked in bacon drippings are the best. Why would I not add fat to my foods? I see no problem there.
I still think that rice, potatoes, and high sugar fruit are not needed for good health. At all.
I dont think anyone said you do. There is no specific foods you need. Only a combination to get adequate and complete nutrients.
And that is crazy about your IR. Good you found your solution.

Most keto diets I've seen and the way people describe eating is very heavy on protein compared to the way most people eat. While that might not be a high protein diet by some standards it is all relative.
Rice, potatoes, other starches and fruits and the like are actually exteremly important for health on a global scale. The reason is that production of animal products is resource intensive and there really isn't enough resources with current technoglies in the world for everyone to have diets heavily based on animal products. The starches provide much needed energy and a good base for additions like fruits. As much as you like adding animal fats to your food, it isn't necessary for a healthy diet. My point is there isn't any single food that is necessary for a healthy diet. So arguments that rice and potatoes aren't necessary for health is really baseless.
Animal products are pretty common all over the world, but the amounts used vary widely. Still I think all the ketosis based diets I've seen use a lot of animal products. Which could be a major disadvantage to some people.

Around here, ketogenic diets seem to mostly be high in fat. Most experts in this field, like Phinney and Volek or Attia, suggest the high fat approach. I believe it is much more common than you realize.
Because it is not a protein heavy diet, it is often not meat heavy. I have meat at two meals a day. Usually. Sometimes less and sometimes more. Yesterday I guess I had meat twice - a burger patty at dinner and a pepperoni stick as a mid afternoon snack. I had cheese on my patty; I guess that counts as animal protein too. Most of my fats yesterday came from coconut cream, nuts, and avocado.
Sure I believe animal fats are healthy. No argument there. Do I think everyone needs to eat mainly animal products? No. But I do think including some in your diet is a good idea.
You have some misconceptions about a ketogenic diet. Your arguments are not all based on actual facts and you've misconstrued some of my statements. You seem to have linked eating lots of animal products with a ketogenic diet, and that just isn't always true. For a minority it is. I know of a few true carnivores but it really is not the norm. To be honest, I know of many more vegetarians so the meat and plant eating probably balances out in the end.0 -

Sounds like you're saying.... Things were easy. You were doing great eating low-carb. Then you stopped, and things are harder. ;-) Come back......we're waiting! :-)
2 words, Keto breath. My husband said my breath smelled like poo, there was NO kissing and every time we spoke I had to hold my hand over mouth even from 10 feet away, which didnt really help! I was constantly chewing gum and mints which only masked it slightly. I was too scared to talk up close to people when I went out.
I have always been meticulous with oral hygiene, and people who had bad breath were a massive turn off for me! I did low carb for 4 solid months hoping the breath thing went away, but it never did. If i was single and never left the house i would so go back to this way of eating as I loved every thing about it, other than that one stinky problem..

Ketogenic Diets Inhibit mTOR, Insulin, IGF-1 and Muscle Growth
Nutrition is arguably the most important component of an athlete or bodybuilder's training regimen. A precise and effective nutritional diet plan produces a biochemical environment that promotes the most efficient muscular adaptations to resistance or endurance exercise. Throughout the years, bodybuilders and athletes have tried to improve their physiques by implementing the ketogenic diet that is high in fat and low in protein and carbohydrate. The fundamental idea behind the ketogenic diet, besides being hypocaloric, is to persuade the body to burn fats rather than carbohydrates or protein due to the lack of carbohydrate and protein in the diet. The excessive fatty acid oxidation in the liver leads to the inevitable conversion of accumulated fatty acid oxidation intermediates into ketone bodies, which were suspected to possess appetite-suppressant properties— thus further facilitating caloric restriction and loss of body fat.
KETOGENIC DIETS DRIVE AN EXTRAORDINARY LOSS OF MUSCLE MASS
While ketogenic diets do tend to stimulate fast weight loss, one of the major drawbacks of the ketogenic diet is that a significant percentage of that bodyweight lost is muscle mass. This negative aspect of the ketogenic diet occurs despite the fact that the body typically prefers to burn either carbohydrates or fat for energy instead of muscle protein, even during times of reduced caloric consumption. For some reason, ketogenic diets generate a greater than normal preference for muscle protein as an energy source during hypocaloric consumption. This phenomenon appears to be partially due to the poor regulation of the all-important nutrient-sensing molecule mTOR from the low-carbohydrate ketogenic diet.
During times of energy surplus, an activated mTOR turns on protein synthesis in muscle cells— leading to enhanced muscle growth and strength. During energy deficits, the inactivated mTOR leads to diminished muscle protein synthesis— leading to muscle atrophy.The consumption of the ketogenic diet has been shown by recent scientific investigation to negatively influence specific hormones and anabolic growth factors that are known to directly or indirectly activate mTOR.This negative influence on mTOR leads to the inhibition of muscle protein synthesis and contributes to the utilization of muscle protein as an energy source.This use of muscle protein as an energy source produces significant loss of muscle mass and strength.
KETOGENIC DIETS INHIBIT INSULIN SIGNALING, PROTEIN SYNTHESIS AND MUSCULAR DEVELOPMENT
Insulin is the primary hormone that responds to increases in blood sugar, causing sugar to be shuttled into the cell for energy consumption or storage. Insulin has also been shown to be one of the most potent activators of mTOR.1 Therefore, the low-carbohydrate feature of the ketogenic diet diminishes insulin signaling and may diminish mTOR signaling. In order to investigate this hypothesis, McDaniel et al.2 investigated the influence of ketogenic diets on insulin signaling. In this study, they showed that low-carbohydrate ketogenic diets significantly diminish insulin action— and this lack of insulin signaling weakens mTOR's ability to stimulate muscle protein synthesis.
GROWTH HORMONE AND IGF-1 FUNCTION ARE DRASTICALLY REDUCED WHILE CONSUMING A KETOGENIC DIET
Growth hormone also integrally participates in mTOR signaling. Since growth hormone is secreted after protein consumption3, the low-protein aspect of the ketogenic diet is further implicated as a potential cause for deficient muscle growth. Consequently, Bielohuby et a1.4 investigated the relationship between growth hormone and ketogenesis. In this study, they demonstrated that the low-carbohydrate aspect of ketogenic diets also leads to a decrease in growth hormone signaling by causing a decrease in the amount of growth hormone receptor levels in the liver. Growth hormone insensitivity in the liver leads to a lack of IGF-1 production, which in turn reduces IGF-1 activation of mTOR, leading to lower protein synthesis levels within muscle cells contributing to muscle atrophy.
HIGH FAT CONSUMPTION FROM THE KETOGENIC DIET ACTIVATES AMPK AND DIMINISHES MUSCLE HYPERTROPHY
Another deleterious consequence that may come from high fat consumption while on a ketogenic diet is the greater amount of fatty acid stored in adipose tissue. The increase in fat storage eventually leads to the release of hormone leptin from the fat cell5, which has been shown to activate the energy-sensing enzyme AMPK in muscle cells and elsewhere.6 AMPK is the cell's master metabolic energy regulator that is typically activated when cellular energy levels are low. However, when high-fat diets— like the ketogenic diet— are consumed, the abundance of fat stored in the fat cell overrides this regulatory principle of AMPK control and triggers AMPK activity, despite the energy status of the cell. AMPK then immediately stimulates fatty acid oxidation. Since AMPK plays such an important role regulating cellular energy, it's no great surprise that AMPK also interacts and regulates mTOR. Moreover, an activated AMPK has been shown to inhibit mTOR function, thus inhibiting muscle protein synthesis and muscle growth. In addition, this increase in adiposity would also lead to a desensitization of the insulin-signaling pathway, which again diminishes the activation of mTOR
.
IDEAL DIET CONTAINS A MORE EVEN BALANCE OF MACRONUTRIENTS THAN FOUND IN THE KETOGENIC DIET
The ideal diet for building muscle and burning body fat apparently does not include extreme approaches such as the ketogenic diet, especially for the athlete and bodybuilder who wants to maximize muscle size and strength while losing body fat.The ketogenic diet's low-carbohydrate feature produces a cellular-energy deficit as the human body preferentially and optimally utilizes carbohydrates as an energy source. Carbohydrate depletion reduces the capacity to perform extremely intense resistance and endurance exercise protocols, which will also decrease the capacity to develop muscle mass and remove body fat. Also, the low-protein attribute of the ketogenic diet forces the utilization of muscle protein as an energy source by breaking down muscle protein into amino acids to burn for energy. This, of course, will drive muscle atrophy as well as deplete strength. Finally, the high fat consumption during the ketogenic diet behaves like a molecular monkey wrench within the muscle tissue— wreaking havoc on several biochemical signaling cascades that negatively influence the proper function of mTOR— depleting muscle mass.
In conclusion, a well-balanced diet with plenty of lean protein to drive muscle protein synthesis with complex carbohydrates to supply plenty of energy during resistance training— along with an economic amount of essential fatty acids for long-term energy during endurance work— seems to be the most effective approach to your nutritional routine.

Ketogenic Diets Inhibit mTOR, Insulin, IGF-1 and Muscle Growth
Nutrition is arguably the most important component of an athlete or bodybuilder's training regimen. A precise and effective nutritional diet plan produces a biochemical environment that promotes the most efficient muscular adaptations to resistance or endurance exercise. Throughout the years, bodybuilders and athletes have tried to improve their physiques by implementing the ketogenic diet that is high in fat and low in protein and carbohydrate. The fundamental idea behind the ketogenic diet, besides being hypocaloric, is to persuade the body to burn fats rather than carbohydrates or protein due to the lack of carbohydrate and protein in the diet. The excessive fatty acid oxidation in the liver leads to the inevitable conversion of accumulated fatty acid oxidation intermediates into ketone bodies, which were suspected to possess appetite-suppressant properties— thus further facilitating caloric restriction and loss of body fat.
KETOGENIC DIETS DRIVE AN EXTRAORDINARY LOSS OF MUSCLE MASS
While ketogenic diets do tend to stimulate fast weight loss, one of the major drawbacks of the ketogenic diet is that a significant percentage of that bodyweight lost is muscle mass. This negative aspect of the ketogenic diet occurs despite the fact that the body typically prefers to burn either carbohydrates or fat for energy instead of muscle protein, even during times of reduced caloric consumption. For some reason, ketogenic diets generate a greater than normal preference for muscle protein as an energy source during hypocaloric consumption. This phenomenon appears to be partially due to the poor regulation of the all-important nutrient-sensing molecule mTOR from the low-carbohydrate ketogenic diet.
During times of energy surplus, an activated mTOR turns on protein synthesis in muscle cells— leading to enhanced muscle growth and strength. During energy deficits, the inactivated mTOR leads to diminished muscle protein synthesis— leading to muscle atrophy.The consumption of the ketogenic diet has been shown by recent scientific investigation to negatively influence specific hormones and anabolic growth factors that are known to directly or indirectly activate mTOR.This negative influence on mTOR leads to the inhibition of muscle protein synthesis and contributes to the utilization of muscle protein as an energy source.This use of muscle protein as an energy source produces significant loss of muscle mass and strength.
KETOGENIC DIETS INHIBIT INSULIN SIGNALING, PROTEIN SYNTHESIS AND MUSCULAR DEVELOPMENT
Insulin is the primary hormone that responds to increases in blood sugar, causing sugar to be shuttled into the cell for energy consumption or storage. Insulin has also been shown to be one of the most potent activators of mTOR.1 Therefore, the low-carbohydrate feature of the ketogenic diet diminishes insulin signaling and may diminish mTOR signaling. In order to investigate this hypothesis, McDaniel et al.2 investigated the influence of ketogenic diets on insulin signaling. In this study, they showed that low-carbohydrate ketogenic diets significantly diminish insulin action— and this lack of insulin signaling weakens mTOR's ability to stimulate muscle protein synthesis.
GROWTH HORMONE AND IGF-1 FUNCTION ARE DRASTICALLY REDUCED WHILE CONSUMING A KETOGENIC DIET
Growth hormone also integrally participates in mTOR signaling. Since growth hormone is secreted after protein consumption3, the low-protein aspect of the ketogenic diet is further implicated as a potential cause for deficient muscle growth. Consequently, Bielohuby et a1.4 investigated the relationship between growth hormone and ketogenesis. In this study, they demonstrated that the low-carbohydrate aspect of ketogenic diets also leads to a decrease in growth hormone signaling by causing a decrease in the amount of growth hormone receptor levels in the liver. Growth hormone insensitivity in the liver leads to a lack of IGF-1 production, which in turn reduces IGF-1 activation of mTOR, leading to lower protein synthesis levels within muscle cells contributing to muscle atrophy.
HIGH FAT CONSUMPTION FROM THE KETOGENIC DIET ACTIVATES AMPK AND DIMINISHES MUSCLE HYPERTROPHY
Another deleterious consequence that may come from high fat consumption while on a ketogenic diet is the greater amount of fatty acid stored in adipose tissue. The increase in fat storage eventually leads to the release of hormone leptin from the fat cell5, which has been shown to activate the energy-sensing enzyme AMPK in muscle cells and elsewhere.6 AMPK is the cell's master metabolic energy regulator that is typically activated when cellular energy levels are low. However, when high-fat diets— like the ketogenic diet— are consumed, the abundance of fat stored in the fat cell overrides this regulatory principle of AMPK control and triggers AMPK activity, despite the energy status of the cell. AMPK then immediately stimulates fatty acid oxidation. Since AMPK plays such an important role regulating cellular energy, it's no great surprise that AMPK also interacts and regulates mTOR. Moreover, an activated AMPK has been shown to inhibit mTOR function, thus inhibiting muscle protein synthesis and muscle growth. In addition, this increase in adiposity would also lead to a desensitization of the insulin-signaling pathway, which again diminishes the activation of mTOR
.
IDEAL DIET CONTAINS A MORE EVEN BALANCE OF MACRONUTRIENTS THAN FOUND IN THE KETOGENIC DIET
The ideal diet for building muscle and burning body fat apparently does not include extreme approaches such as the ketogenic diet, especially for the athlete and bodybuilder who wants to maximize muscle size and strength while losing body fat.The ketogenic diet's low-carbohydrate feature produces a cellular-energy deficit as the human body preferentially and optimally utilizes carbohydrates as an energy source. Carbohydrate depletion reduces the capacity to perform extremely intense resistance and endurance exercise protocols, which will also decrease the capacity to develop muscle mass and remove body fat. Also, the low-protein attribute of the ketogenic diet forces the utilization of muscle protein as an energy source by breaking down muscle protein into amino acids to burn for energy. This, of course, will drive muscle atrophy as well as deplete strength. Finally, the high fat consumption during the ketogenic diet behaves like a molecular monkey wrench within the muscle tissue— wreaking havoc on several biochemical signaling cascades that negatively influence the proper function of mTOR— depleting muscle mass.
In conclusion, a well-balanced diet with plenty of lean protein to drive muscle protein synthesis with complex carbohydrates to supply plenty of energy during resistance training— along with an economic amount of essential fatty acids for long-term energy during endurance work— seems to be the most effective approach to your nutritional routine.

No you're not? Really?
I won't claim to know much about lifting but to claim that people can;t gain muscle while eting low carb seems ... goofy. And out dated. Is this info for a medicinal ketogenic diet rather than nutritional ketogenic diet? The first is low protein while the second is not.
Maybe look through ketogains and see what they have to say there. People like"Darth Luigi might take exception to your denial that people can gain muscle while on a keto genic diet. Maybe this? http://ketogains.com/2016/01/protein-synthesis-without-carbs/
I won't say that someone who is eating high carb with high IGF-1 and insulin may bulk faster than someone on a ketogenic diet but I seriously doubt the difference is something the vast majority of people should be concerned with. My guess is that only top bodybuilding competitors would worry about this. Don't those people supplemen with IGF-1 and insulin. Not something for the typical Joe to worry about.0 -

If you are a volume eater like me or if you tend to eat more vegetables than keto allows, you may find it very hard to adapt your portions and as a result may overeat and gain weight like I did.
If your food preferences are very far removed from what is allowed on keto, you may find it boring and even stressful.
If you are prone to chronic depression, stress, anxiety, cortisol issues, hormonal issues related to menstrual cycle or certain GI issues keto may be a very bad idea for you.
If you don't take very careful care to keep your electrolytes balanced and you are prone to imbalances you may experience bad side effects.
If your social food choices are often high in carbs it may be a bit hard to adapt to social situations.
You may still need to count calories if a ketogenic diet does not produce the desired spontaneous calorie reduction, making it unnecessary.
However, you may not experience any of the above and may find it easier to eat a ketogenic diet like some. The only way to find out if this diet is easier for you than good old moderation is to try it out for a couple of months and see how you feel. If it feels easy and pleasant, continue, if not, you can simply go back to what feels easier to you. It's not like you are signing a contract.

It would depend on your goals. If you want a good aesethic and maintain or increase muscle mass during a deficit than carb timing or total might be important.

Hmm. I guess not. I'm looking but I am mainly finding how ketosis is muscle sparing and personal stories rather than good for protein syntheisis. Thia is an interview with Volek that discusses athletic performance, and how it does not suffer from ketosis, but I stopped looking. http://www.truehealthunlimited.com/blog/lowcarbapproach There just isn't much done on very low carb high fat diets and athletic performance yet.

I fifured there was very limited research. In fact, there isnt nearly that much research when it comes to bulk... well not compared to losing weight.
I have no doubt that i can be done and i know there are several members on low carb and keto diets that have impressive results. But as noted, while it can be done, it may not be as effective or apply to as great of a population.
But ultimately you have to chose a method that supports ones goals. Some its just health.. others its more aesthetic and performance and others its powerlifting.0 -

Body builders tend to use very complex diets, sometimes claiming it is a ketosis diet but they also carb load on a schedule to match some workouts. It is probably all over the map. In general a lot of body builders put a huge amount of effort into their diets. I don't think there would be many serious body builders on a pure LCHF ketosis diet.0
