There is debate regarding whether obesity or insulin resistance is the cause of the metabolic syndrome or if they are consequences of a more far-reaching metabolic derangement. A number of markers of systemic inflammation, including C-reactive protein, are often increased, as are fibrinogen, interleukin 6, tumor necrosis factor-alpha (TNF-α), and others. Some have pointed to a variety of causes, including increased uric acid levels caused by dietary fructose.[18][19][20]

As a matter of fact, in animal models intracerebroventricular injections of long-chain FA reduced hypothalamic expression of NPY. NPY is an important orexogenic neuropeptide that is a downstream target of leptin and insulin in the hypothalamus. In some forms of hyperphagic obesity, characterized by elevated plasma leptin and insulin levels, the lack of action of insulin on NPY expression could explain the pathological condition. Central administration of oleic acid, fatty-acid synthase, or CPT-1 inhibitors prevents the rise in hypothalamic NPY mRNA induced by fasting (Obici et al., 2003). But glucose level is also involved in KD's food control mechanisms. According to glucostatic theory (Mayer, 1955) data indicates that ketosis did not influence FA glucose but instead stimulated the elevation of post-prandial glucose (Sumithran and Proietto, 2013) in non-diabetic subjects, while in diabetics there was a reduction of fasting glucose (Westman et al., 2008). It is important to note that carbohydrate availability may increase cellular levels of long-chain FA-CoA through an increase of malonyl-CoA, which inhibits oxidation of FAs.

Improved insulin markers: In Type II diabetes, fasting insulin levels are often elevated, and insulin has less of an effect (meaning it takes longer for blood glucose to fall after the post-meal increas). Whilst evidence is not conclusive, some studies have claimed to demonstrate an improvement in insulin sensitivity with the ketogenic diet104. The evidence supporting a decrease in fasting insulin levels with a ketogenic diet has been demonstrated more consistently 104 , 105 .


An increase in fat burning ability could improve endurance capacity: as body fat represents a larger store of energy (150,000 kCal) compared to carbohydrate (2000 kCal), a greater ability to burn fat during exercise could prolong endurance performance. Whilst the theory appears sound, there is only one study showing an IMPROVEMENT in performance with a low carbohydrate diet18, with many showing no clear benefit of a low carbohydrate diet 19 ,20.    

I have great respect for Harvard Medical School. I notice that they support their readers posting comments and I am most appreciative of the article and all the many thoughtful comments by the readers. The readers seem to have the most expertise here and I hope that the doctor who wrote the article will think long and hard about the comments by readers. After 35 years of clinical practice in mental health, I notice that all issues of emotion involve medical issues, nutrition, and the gut bacteria. I would say that these issues and all of the executive brain functions seem to improve with ketogenic principles. For those that apply it in a flexible and smart manner, it appears to improve every area of their lives. I strongly encourage the author of the article to take one class via The Institute for Functional Medicine. If he is open to more learning he can take more classes and get certified. I’m sure a fine doctor, he will be an even better doctor and personally healthier, if he gets more training. Are we all open to new learning(especially us healthcare providers)?
Some investigators feel that mitochondrial dysfunction and compromised brain glucose metabolism may play a role in the development of autism. As autism is sometimes accompanied by seizures such as those seen in epilepsy (which could be improved by the ketogenic diet), the diet has been trialled in a small number of case studies. These cases have shown that the ketogenic diet can lead to improvements in the childhood autism rating scale score 78 ,79, however dietary adherence may prove even more of a challenge with these children, decreasing the viability of the ketogenic diet as an intervention.

Low blood sugars can be caused by not eating enough, or by trying to lower your sugar too quickly. A blood sugar under 60 is considered dangerous. It can lead to confusion or loss of consciousness, which can be deadly. It is important to have a snack with you at all times in case this happens to you. If it does happen, think about what you did or didn’t do that lead to the low number. If it happens often, start writing things down to help you track what the cause is so that you can avoid it.

Good day every one i want to inform the general public how i was cured from Herpes Virus Patient for good Five years i was loosing hope on myself my Boyfriend ran away from me because of my situation one day i was online and i saw testimony on how Dr ozalogbo help a lady to cure herpes virus,so i still continued searching and then, i saw a testimony of someone again who has been healed from “HIV AIDS by this same Man Dr ozalogbo and she also gave the email address of this man and advise we should contact him for any sickness that he would be of help, so i emailed Dr ozalogbo telling him about my HERPES Virus he told me not to worry that i was going to be cured…oh i never believed it,well after all the procedures and remedy given to me by this man 2 weeks later i started experiencing changes all over me as the Dr ozalogbo assured me,after some time i went to my doctor to confirm if i have be finally healed,behold it was TRUE,that is why i want you to join me in thanking Dr ozalogbo for saving my life if you need his help please contact him via email: (ozalogboshrine@yahoo.com) or whatsapp him with he’s cell phone number;+2348162562991 he is a true healer…..


I can’t find an 8×4 pan in the local stores, so while I wait for one to be shipped I went ahead and made these into hamburger bun shape. I don’t have a kitchen scale so I just measured everything super precise and got great results. I only have NOW brand psyllium husk powder so yes, they are an odd shade of purple but they taste great so I don’t care. What I really wanted was a vessel for butter and it made for a great snack before bed- which I know I’m not supposed to have but I was too curious to wait until morning! 🙂 Thanks for the update on this recipe, it made all the difference!
I am not a baker so I studied all the comments carefully, ordered the blanched almond flour but not the Robb psyllium powder, used instead a generic (Equate) brand; didn’t weigh anything and don’t have a convection oven. Baked for 60 minutes. This bread fell a little but after complete cooling (2 hours), I sliced this bread down the middle and found it pretty near perfect in consistency. The taste of it is heaven. Small bit of gumminess, so will reduce by 1 oz H2O next time. Thank you for sharing this amazing recipe.

Although there are numerous sites of mtROS formation, the most prominent are those in the mtETC, where the superoxide radical (O2•−) is formed through reduction of O2 by leaked electrons, particularly at complexes I and III [41, 53–55]. Production of O2•− at complex I is particularly high during reverse electron transport (RET), which occurs when a high proton-motive force (Δp) develops across the inner mitochondrial membrane in conjunction with the pool of coenzyme Q (CoQ) being in a highly reduced state (i.e., mostly present as ubiquinol) as a result of electron transfer through complex II and electron transfer flavoprotein:ubiquinone oxidoreductase (ETF-QO) [56–62]. This dependence of mtROS production on Δp during RET is mainly influenced by proton gradient (ΔpH) [59].
Unfortunately I did not care for this recipe. I’ve been cooking snow I was 8yrs old and cook everything from scratch but I always make a recipe and follow it to a T the first time..based on that..this was like eating scrambled eggs..the taste was very very eggy! Texture was like scrambled eggs too on the inside.. Also very very salty!! I’m wondering if taking out the yolk and eliminating half the salt could make this better. I’m bummed because I really wanted to like it. 
The oral glucose tolerance test (OGTT), or glucose tolerance test is a blood test used (not routinely however) to diagnose diabetes, and gestational diabetes. Information in regard to reliability of the oral glucose tolerance test is important, as some conditions (common cold), or food (caffeine), or lifestyle habits (smoking) may alter the results of the oral glucose tolerance test.
Why is the keto diet good for you? A keto diet is one that prioritizes fats and proteins over carbohydrates. It can help reduce body weight, acne, and the risk of cancer. Find out about the mechanisms through which it achieves these benefits and the research that supports it. This MNT Knowledge Center article also discusses the risks of the diet. Read now
Maria, Maria. I really want this bread to work for me, but I just made my 4th attempt and it’s in the trash. I have read every comment about this bread, watched the video, I have all your recipe books and all the recipes come out great…but THIS bread is my nemesis! I don’t mind that it comes out purple, but my bread doesn’t rise like yours. It’s maybe 2-3″ tall, and it’s only porous on the top, while the bottom is soggy. Then, if I flip it over in the bread pan and bake it longer, to try to dry out the soggy part, the formerly soggy part turns porous and the previously porous part turns soggy. In other words, no matter what I do, the bottom half is disgusting. Is it the pan I’m using?? I have tried aluminized steel and stainless steel, both 9 x 5. I measure everything to the ounce or gram and run my psyllium husk through the coffee grinder a few times before weighing/adding it. I am really determined not to get a half soggy half bread-like purple brick out of this! Thoughts?
The brain is different as it is dependent on carbohydrates as a fuel source. This is because fats cannot easily cross the blood-brain barrier. The inability to make use of energy within fat poses a problem during periods where there is limited carbohydrate in the diet. If blood glucose levels fall to low, brain function declines. Relatively little energy is stored as carbohydrate (2,000 kCal) compared to fat (150,000 kCal). The body's store of carbohydrates runs out with a few days of carbohydrate restriction. Once glycogen is depleted, a cascade of hormonal signals causes the body to increase the release of stored fats (from adipose tissue). Signals include the fall in blood insulin, rise in a hormone called glucagon and an increase in cortisol (stress hormone) 1. The increase in blood fatty acids is a key trigger for ketone production (ketogenesis). Unlike fats, ketones are readily used as a fuel in the brain. Fatty acids are converted into ketone bodies in the liver, and ketones can provide up to 60% of the brain's energy requirements during starvation 2. The graph below shows how BHB (black triangles) builds up in the blood over many days until it reaches a level of around 6 mM.
Increases in cholesterol levels need discussion too. We do see temporary increases in cholesterol levels often as individuals transition onto a ketogenic diet. However, when you examine lipid particle size (a more important way to look at the cardiovascular risks), the risk pattern doesn’t seem to increase with a ketogenic diet. Harvard Health has written about lipid particle size here before: http://www.health.harvard.edu/womens-health/should-you-seek-advanced-cholesterol-testing-
Before we get started, here’s a short recap of the tips so far: The first and most crucial piece of advice was to choose a low-carb diet. The next were eating when hungry, eating real food, eating only when hungry, measuring progress wisely, being persistent, avoiding fruit, beer and artificial sweeteners, review your medications, stressing less and sleeping more, eating less dairy and nut products, stocking up on vitamins and minerals, using intermittent fasting and finally, exercising smart.
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.    
Well, everyone, I am sensitive to psyllium so I experimented and it kind of worked! I made a half recipe using chia seed I ground in my Vitamix into 5 buns. They didn’t really rise but the flavor was quite good. Might add garlic and onion powder next time. I was able to slice the skinny bun and have a burger on it. Yum! Hadn’t had a burger on a bun for ages! Worth a try! I did weigh everything and was very precise so inaccurate quantities would not be an issue. Maria, any ideas on how to make this mixture rise some? I’m sure I’m not the only one with psyllium issues. Can’t have flax much either and I think if I have the chia too often that will give me tummy trouble also. One more question Maria. Is there a reason for no salt in the egg white protein bread? I don’t really like the flavor or texture but thought salt and seasonings would help. Thank you, Maria! You have made my meals so much more enjoyable! So grateful!
As ketones are the only other metabolic substrate that can fuel the brain, there is a compelling mechanism whereby ketosis could improve brain energy metabolism and therefore improve symptoms of AD. Despite a declining ability of the brain to use glucose, cerebral ketone metabolism is preserved in AD (Castellano2015). This means that ketosis could be used to prevent an energy deficit in the brain. Another possibility is that ketone metabolism decreases mitochondrial damage caused by oxidative stress in the brain52. Individuals with AD tend to have increased mitochondrial oxidative stress, which can worsen brain energy production and increase plaque and tangle formation53.  
I am a little confused about beating the egg whites with a hand mixer. I used 12 large egg whites as the recipe says. However, I did not add cream of tartar as I have none. I have been beating these egg whites for almost 40 minutes with an electric hand mixer and I still have not yet come to the consistency as your photo shows for stiff egg whites. So my questions are, is this amount of time normal for beating the egg whites? And what amount of time would you recommend if this is not the normal amount of time?
On the contrary, in the brain, as mentioned above, the increase of AMPK activity leads to higher food intakes. But the effect of AMPK in the brain is more complicated; mice lacking AMPKa2 in pro-opiomelanocortin neurons develop obesity, while the deficiency of AMPKa2 in agouti-related protein neurons results in an age-dependent phenotype. Thus, the conclusion is that even while AMPK is a regulator of hypothalamic functions, it does not act as a signal for energy deficit or excess (Claret et al., 2007). However, the picture is more complex than this (Figure ​(Figure3);3); BHB induces AgRP expression while increasing ATP and inhibiting AMPK phosphorylation (Cheng et al., 2008). Moreover, Laeger and colleagues have recently demonstrated that under physiological conditions BHB decreases AMPK phosphorylation and AgRP mRNA expression in GT1-7 hypothalamic cells (Laeger et al., 2012).

I never believed but i have to give a try because i was desperately in need of cure to the deadly disease that i have been living with. So i contacted him and we discussed how to get the cure and Dr maggi told me he cured with herbal medicine which i will order for and it will be delivered to me. Which i did what he wanted and to my greatest surprise the herbal medicine was delivered to me at my address which i gave to him, with instruction on how to apply was also given to me by Dr Maggi. Then i started to use the herbal medicine, so after four weeks of using the herbal medicine, i saw physical changes and went for test at two separates hospitals and i was totally cured, i am here to say thanks to you again Dr Maggi for saving me from the deadly herpes disease. Anyone with such disease can also contact Dr Maggi through his EMAIL:maggiherbalcenter@gmail. com. You can also CALL him on +1(305)697-6952 OR whatsap him +1(306)993-9253,

I am very happy today to share this amazing testimony on how Dr. MAGGI the herbal doctor was able to cure me from my HIV Virus with his herbal medicine. I have been a HIV patient for almost 8 months now and have tried different methods of treatment to ensure that I am cured of this terrible disease, but none worked for me, so I had to leave everything to God to handle as I was a Christian who had faith that one day God would intervene in my life, yet I felt so sad and desperate as I was losing almost everything due to my illness, A few months ago while I was surfing the internet I saw different recommendation about Dr MAGGI on how he have been using his herbal Medicine to treat and cure people, these people advice we contact Dr. MAGGI for any problem that would help immediately, I contacted Dr MAGGI and I told him how I got his contact and also about my disease, after some time Dr.MAGGI told me to have faith that he would prepare medicine for me a medication of herbal herbs, he told me I would take this medicine for a few weeks and also asked for my home address so as possible for him to submit the drug for me, so my good friends after all the process and everything Dr MAGGI actually sent me the medicine, I took it as I was directed by Dr. MAGGI, after a few weeks passed, while on Dr.MAGGI medication I began to experience changes in my body, I had to call my doctor at the hospital for some blood test after test my hospital doctor told me that I was no longer with the Hiv virus and my blood is pretty good, I can’t even believe this, Friends well today i am Hiv Negative and i want everyone to know that there is a cure for Hiv for those who will contact Dr MAGGI after reading my testimony, you can kindly contact Dr. MAGGI on Email:Maggiherbalcenter@gmail.com or call +1(305)697-6952 OR whatsap him +1(306)993-9253,or you can also check him on his Wixsite: https:maggiherbalcenter.wixsite.com/drmaggi
I made it tonight and use a mini loaf pan. It came out delicious. I used the http://www.tasteofhome.com/article/how-to-cut-down-recipes/ link to adjust the recipe measurements using the one third column. I used 2 egg whites. The slices will be small but it was delicious with melted butter. Keto bread recipes and I have tried quite a few have not turned out well for me. I do not like to waste expensive ingredients that is why I will usually do a small amount first. This recipe has been the exception. It is good simple and delicious. I will make it again using the recipe as written. Note: I whipped the egg whites for 10 minutes to get the right consistency. I hope this helps and thank You Maya for finally for me making a bread that tastes great and is easy to make.
First of all, thanks for the recipe. I tried it yesterday with coconut flour and egg whites, and I failed miserably. It rose 5 or 6 times in volume and then collapsed like the world economy. Also, it was very moist on the inside. I’ll try the almond flour version with half the baking powder and full eggs this time, but I’m having trouble wrapping my head around measurements. If 1 and 1/2 cup of almond flour is 5oz, how can 1/2 cup of coconut flour be 2.5oz (equalling 7.5oz for 1 and 1/2 cup)? If anything, almond flour is more dense, not less.
I have been making Maria’s bread in my convection oven for a while and I had to lower the temp considerably to make sure it didn’t burn on the outside (even with a shorter baking time). I have a “portable” convection oven and I had always assumed that convection was the way to go for baking. Then I read some more about it and saw that convection is best for meats, etc. but not for baking, and I tried using the ‘normal” baking setting. My bread was MUCH better baked on normal. I used the temperature in the recipe and the timing and it came out perfect. No monkeying around with settings or duration.

A friend who gave me your recipe said to drink a glass of water with it.How many slices of the amazing bread can one eat without the psyllium causing a problem for a normal person per day?The replies are so long,but from what I did read no one complained about any problems caused by eating the bread or having to drink something. So can I eat this bread like other breads without drinking something?
The graph below, also from the Cahill and Veech paper, shows the blood chemistry of a person starving for 40 days.  Within about 3 days, a starving person’s level of glucose stops falling.  Within about 10 days they reach a steady-state equilibrium with B-OHB levels exceeding glucose levels and offsetting most of the brain’s need for glucose. In fact, the late George Cahill did an experiment many years ago (probably would never get IRB approval to do such an experiment today) to demonstrate how ketones can offset glucose in the brain. Subjects with very high levels of B-OHB (about 5-7 mM) were injected with insulin until glucose levels reached 1 mM (about 19 mg/dL)!  A normal person would fall into a coma at glucose levels below about 40 mg/dL and die by the time blood glucose reached 1 mM.  These subjects were completely asymptomatic and 100% neurologically functional.
The findings of a stable (Chearskul et al., 2008) or slightly increased response (Sumithran et al., 2013) of post-prandial FFA after KD can be viewed in the nutrient-static context. Elevated circulating FFA may actually reduce food intake and glucose production through actions on specific hypothalamic neurons (Obici et al., 2003). It has been suggested that this effect could be mediated by the increase of cellular concentration of long-chain FAs-CoA in the arcuate nuclei of the hypothalamus (Obici et al., 2003).
Urine test for diabetes: What you need to know Urine tests for diabetes check for protein, ketones, and glucose. They are frequently used for diagnosing and monitoring diabetes, and to assess people who are experiencing symptoms, such as fatigue or nausea. Depending on the results, recommendations may be given about medication or lifestyle changes that could help. Read now
Most people who have metabolic syndrome already have a closely related condition called insulin resistance, which is when the body stops responding to insulin (a hormone produced in the pancreas). After the food we eat is converted into a type of sugar called glucose, insulin is what enables the glucose to enter the body’s cells and be used as energy. For someone who is insulin resistant, however, the glucose builds up in the blood, setting the stage for damage.
The primary problem in metabolic syndrome is insulin resistance. In the body's attempt to compensate for insulin resistance, extra insulin is produced, leading to elevated insulin levels. The elevated insulin levels can lead, directly or indirectly, to the characteristic metabolic abnormalities seen in these patients. Frequently, the insulin resistance will progress to overt type 2 diabetes, which further increases the risk of cardiovascular complications.
So happy I tried this recipe there are so many out there and you pick one to make and it has always been disappointing until now. I pinned both bread recipes the yeast one and the 90 second one and went for the 90 second since because not enough almond flour on hand. Wow so good!! No weird taste it really does toast up great like regular toast finally get that crunch. Thank you for all the work you put in to perfecting recipes. Finally found a bread recipe I will make again and again. Will try the yeast one soon. 🙂
Transfer bread dough to prepared loaf pan, using a wet spatula to even out the top. Cover with a kitchen towel and place in a warm draft-free space for 50-60 minutes until the dough has risen just past the top of the loaf pan. How long it takes depends on your altitude, temperature and humidity- so keep an eye out for it every 15 minutes or so. And keep in mind that if you use a larger loaf pan it won't rise past the top. 
So, now, I’ve got another loaf in the oven. I doubled the salt, ground up the Psyllium Husk in my Blend Tec (instead of the shoddy thing I used the first time) and reduced the baking soda to 3 tsp. I also (accidentally) ended up with 1 egg yolk in there. Hopefully, that won’t cause too much of an issue. I weighed all my ingredients and I’m hopeful that this batch will give me the results I am looking for. I would *love* a grilled cheese sandwich for a quick-fix dinner with my keto plan. 🙂 Thanks for the recipe. I’ll let you know how this batch turns out.
Many questions about the role of such an important intermediate of lipid metabolism remains unanswered, e.g., the role of BHB in food control. For example, whether or not BHB could act as a satiety signal in the brain, considering its role in energy supply to CNS. We have to consider that the effects of KBs on hunger reduction can only be seen after many days following fasting or KD initiation (Paoli et al., 2010); this is consistent with the abovementioned threshold of brain utilization of KB as an energy source, i.e., 4 mmol/L (Veech, 2004), which is close to the Km for the monocarboxylate transporter (Leino et al., 2001). During the first days of fasting or KD there is a rise of BHB and adiponectin concentrations (Halberg et al., 2005). One of the putative causes of hunger in starved humans may be due—together with other causes—to adiponectin. When adiponectin binds to its receptor AdipoR1, AMP-activated protein kinase (AMPK) is phosphorylated in the ARC of the hypothalamus (Valassi et al., 2008). The increase of AMPK activity in the hypothalamus may increase food intake and hepatic glucose output in mice while the decrease seems to reduce food intake (Zhang et al., 2009). KDs can also act similarly to a caloric restriction on AMPK (Newman and Verdin, 2014). Interestingly, AMPK seems to have opposing actions on the liver, muscle tissues and the brain: in liver and muscle AMPK activation increases FA oxidation by decreasing malonyl-CoA concentrations (Malonyl-CoA is the first intermediate in the lipogenic pathway and is also an inhibitor of carnitine palmitoyltransferase-1 (CPT-1). CPT-1 activity can be limiting for FA oxidation), through the inactivation of the acetyl-CoA carboxylase 1 (ACC1). AMPK can also increase the activity of malonyl-CoA decarboxylase (MCD), which enhances the decrease of malonyl-CoA levels.
I made this bread several times by grinding the jay robb psyllium husks, but never got a good loaf. Then I bought the now brand psyllium husk powder and it worked without turning purple. I did have to weigh everything and cook it about an hour and a half or longer. When I cooked it the first time it sank in the middle. If you don’t have a vitamin or blend tech this is the way to go.
Fathead dough is a low carb/keto dough that is made out of cream cheese, mozzarella cheese, eggs and a flour substitute. It started out as a pizza crust recipe published by Tom Naughton while he was creating the movie Fat Head. The recipe became an internet viral sensation and has since been adapted and modified for recipes beyond pizza crust, such as breadsticks, bread rolls and bagels.
