A ketogenic diet could be an interesting alternative to treat certain conditions, and may accelerate weight loss. But it is hard to follow and it can be heavy on red meat and other fatty, processed, and salty foods that are notoriously unhealthy. We also do not know much about its long-term effects, probably because it’s so hard to stick with that people can’t eat this way for a long time. It is also important to remember that “yo-yo diets” that lead to rapid weight loss fluctuation are associated with increased mortality. Instead of engaging in the next popular diet that would last only a few weeks to months (for most people that includes a ketogenic diet), try to embrace change that is sustainable over the long term. A balanced, unprocessed diet, rich in very colorful fruits and vegetables, lean meats, fish, whole grains, nuts, seeds, olive oil, and lots of water seems to have the best evidence for a long, healthier, vibrant life.
For a given quantity of fuel, the maximum amount of work that can be obtained from that fuel in a closed system is called ‘the Gibbs free energy’ (G). This takes into account the inherent ‘heat’ (combustion enthalpy (H)) and a property called entropy (a measure of tendency towards ‘disorder’ (S). The change in Gibbs free energy (∆G) is related to the change in combustion enthalpy (∆H), change in entropy (∆S) and the temperature (T):
Bread is one of the foods that people miss most on keto – at least I know I did – and a loaf of almond flour bread is a great alternative. But, for a lot of folks, it’s quite a task to make, because you have to separate eggs, and whisk the whites to stiff peaks and so on. So, for those folks on the go, or those without ovens and those simply without the time or inclination to cook, this 90-second keto bread made in the microwave is the perfect solution. It’s literally as simple as mixing a few ingredients in a mug and popping it in the microwave. And in less than two minutes you have a keto friendly bread, almost as easy as putting bread in the toaster.
The exact mechanisms of the complex pathways of metabolic syndrome are under investigation. The pathophysiology is very complex and has been only partially elucidated. Most patients are older, obese, sedentary, and have a degree of insulin resistance. Stress can also be a contributing factor. The most important risk factors are diet (particularly sugar-sweetened beverage consumption), genetics, aging, sedentary behavior or low physical activity, disrupted chronobiology/sleep, mood disorders/psychotropic medication use, and excessive alcohol use.

Also that’s absolutely wrong information about microwaves. Breast milk is not microwaved because of the uneven heating which can cause ‘hot spots’ which will lead to your baby’s mouth being burned. It does nothing to the nutrition of the milk itself or the proteins. There is a lot of fear mongering about microwaves and most people don’t understand the basic principle of how it works. It’s like people who blindly say there are ‘chemicals’ in food not realizing that everything is a chemical compound, even drinking water. So don’t worry 🙂
The effects of a ketogenic diet on cholesterol and triglycerides is complex. It is dependant on the exact composition of the diet, the genetic and physical characteristics of the individuals studied and other hormonal and environmental factors. Therefore, blood lipid changes whilst on the ketogenic diet can vary between individuals. This means that it is advisable to track your personal levels by having a blood test before starting the ketogenic diet and to follow this with regular testing to monitor any changes.

It is, however, worth noting that according to the customary convention (Woodyatt, 1921 ; Shaffer, 1921) this diet is not ketogenic since the ratio of ketogenic(FA) to ketolytic (G) aliments is 1.09. Indeed, the content of fat would have to exactly double (324 g daily) to make the diet ketogenic (FA/G>1–5).
Oh Maria! Your bread recipe is fabulous! I have been playing around with it a little because the psyllium was a little too much for my gut! Went to 8 TBS of psyllium and added 2 TBS of Jay Robb Protein Isolate powder and a little sweetener (trying to make a yeasty flavor) I also turned it into buns which are easier for my household. I must say they turned out great! I even added caraway seeds to one batch for a rye flavor! I cannot thank you enough for making it so much easier to eat right when you have BREAD, ROLLS and DESSERTS that are fabulous!
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.
Hi Mindy, That sounds very odd. The salted butter is probably why it was too salty, but I think one of your ingredients must have gone bad, because the bread shouldn’t have a bitter or sour taste at all. Or did you use baking soda instead of baking powder? That would taste both bitter and sour, so that could be it. It needs to be baking powder, not baking soda. Hope you’ll try again!
Ketosis is deliberately induced by use of a ketogenic diet as a medical intervention in cases of intractable epilepsy. Other uses of low-carbohydrate diets remain controversial. Carbohydrate deprivation to the point of ketosis has been argued to have both negative and positive effects on health. Ketosis can also be induced following periods of fasting (starvation), and after consumption of ketogenic fats (such as medium chain triglycerides) or exogenous ketones.
Now, back to the real question at hand. Why would our body make these substances? To understand why or when the body would do this requires some understanding of how the body converts stored energy (the food we eat or the energy we store in our body, i.e., fat or glycogen) into phosphate donors. For a refresher on this process, please refer to the video in this post, specifically the section from 2:15 to 13:30.
I can’t believe my GENITAL HERPES and HIV is really cured, i never thought and believed that one day i will live on earth cured of this disease.i have been suffering of this deadly disease Herpes since 7years ago.Happiness is all i see now i never thought that i will live on earth before the year runs out this is a miracle A shot testimony on how i was cured for my HERPES and HIV Virus diseases by Dr Ofemu with his Herbal Root Herbs Medicine, Although this is almost too impossible to believe, but I am here to fulfill my promise to Dr Ofemu, I am a survivor, I am a living proof of this medication, at first it sounded so fake, but my mum encouraged me to continue with the medication, within 3 days I notice the sours in my genitals were all dried up and my tongue stopped paining me, so i stopped taking my Drugs and focused on the herbal medication. I felted my body coming back to life, my skin, my face, no more body weakness and my mum kept praying for me, she was really happy when i was tested negative. This unbelievable transformation have also brought me closer to God, and thanks to Dr Ofemu for his regular checkups, calls, sms and chats. I am CURED, I am CURED and I repeat I AM CURED! I have been a slave of HIV for 3years but it took just 19 days for my cure!

Ketones may also be important, or even necessary, for the bioenergetic signaling associated with mitohormesis. As will be discussed later, peroxisome proliferator-activated receptor α (PPARα) is a nuclear receptor that is responsible for many of the bioenergetic adaptations associated with nutritional ketosis and mitohormesis . In mice, a ketogenic diet (% energy: 90 fat, 0 carbohydrate, and 10 protein) increased blood BHB concentration to 1-2 mM and upregulated expression of numerous PPARα targets in the liver . However, in mice fed a nonketogenic low-carbohydrate diet (% energy: 75 fat, 15 carbohydrate, and 10 protein), which did not raise blood concentration of BHB, the increased expression of PPARα targets did not occur , implying that induction of PPARα signaling by a ketogenic diet is dependent on ketones. This response may be, at least in part, a result of the epigenetic effects of BHB. In addition to HDAC inhibition, BHB also influences gene expression through β-hydroxybutyrylation of histone lysine residues . In the livers of mice subjected to prolonged fasting, this β-hydroxybutyrylation has been associated with upregulation of PPAR signaling, oxidative phosphorylation, fatty acid metabolism, the proteasome, and amino acid metabolism related to redox balance . Upregulation of these pathways is largely influenced by β-hydroxybutyrylation of the histone residue H3K9 , which is also involved in the upregulation of antioxidant defense through BHB-induced HDAC inhibition . This potential for BHB to influence expression of both mitochondrial and antioxidant genes through a common histone residue is further indication of the overlap between bioenergetics and antioxidant defense and suggests that if mitohormesis is indeed induced during nutritional ketosis, induction may be dependent on ketones and may therefore not occur during a low-carbohydrate diet that is not ketogenic.
Although the majority of links between energy sensing and antioxidant defense are manifested further downstream, there is some direct influence at the level of AMPK and sirtuins. AMPK is activated by oxidative stress [259, 260], likely through ATP depletion and a subsequent increase in the AMP to ATP ratio, or facilitation of tyrosine phosphorylation, which occurs independently of AMP and ATP concentrations . SIRT3 contributes more directly to antioxidant defense by deacetylating and activating SOD2 [261–263]. The overlapping effect of SIRT3 on antioxidant defense and bioenergetics is further supported by SIRT3 knockout increasing lipid peroxidation in conjunction with decreased O2 consumption in mouse skeletal muscle and also by SIRT3 knockdown increasing H2O2 production and decreasing O2 consumption in myoblasts .
Ketosis is the result of following the ketogenic diet, which is why it’s also sometimes called “the ketosis diet.” Ketosis takes place when glucose from carbohydrate foods (like grains, all sources of sugar or fruit, for example) is drastically reduced, which forces the body to find an alternative fuel source: fat. Although dietary fat (especially saturated fat) often gets a bad name, provoking fear of weight gain and heart disease, it’s also your body’s second preferred source of energy when carbohydrates are not easily accessible.
Monica, i use NOW psyllium as well but GRIND i t just in case, my lower half is still under cooked at 75 min on 325, but the top half is beautiful. This is my 3rd attempt. I don’t think it is the psyllium powder and the first time i used silicone pan this last time metal. I’m frustrated as I’m throwing away close to 5lbs almond flour for 4th attempt. My pan is standard size loaf pan maybe i should divide mixture into 2 smaller ones. Oh also, the first time I baked it at 375 for 60 min. The 2nd reduced water and psyllium. The 3rd was the first few lines above, still no luck, someone HELP

Love how quick and easy these are to whip up and they’re really satisfying to eat. Made them tonight to use as hamburger buns; sliced them in half and grilled them and they worked great. I think the coconut gives them some sweetness that reminds me of cornbread (I used a coconut/almond milk blend for the liquid). I think we’ll be making a lot of these!
I’m following the ketogenic diet and I find it very easy, pleasant and varied. I can even say that my diet today is more varied than the previous one. I do not intend to leave this diet and I cannot really see why. My initial focus was not to lose weight, I’ve always been lean, but to feel better, well disposed. And I got it! I am very pleased, I have read a lot about it (including scientific literature) and I have influenced other people who need to lose weight or improve some aspects of their health. But from the beginning I went on my own way, without the help of a nutritionist because I did not want to suffer the influence of others’ ideas.
I have a loaf cooling on the counter right now. I couldn’t wait to take a piece of it so I hacked a piece off after 5 minutes and tasted it. I don’t get it, it’s the closest thing to real bread but does’t have any wheat in it! How can the crust taste so good?! I’m on a low carb diet so I have suffered through all sorts of weird tasting bread. This one is chewy, with nooks and crannies for sauces and butter. Mine came out purple, but I think it’s a lovely color. I used the bulk psyllium husk powder at my local health food store.
People who have metabolic syndrome typically have apple-shaped bodies, meaning they have larger waists and carry a lot of weight around their abdomens. It's thought that having a pear-shaped body — that is, carrying more of your weight around your hips and having a narrower waist — doesn't increase your risk of diabetes, heart disease and other complications of metabolic syndrome.
Dietary fiber intake provides many health benefits. However, average fiber intakes for US children and adults are less than half of the recommended levels. Individuals with high intakes of dietary fiber appear to be at significantly lower risk for developing coronary heart disease, stroke, hypertension, diabetes, obesity, and certain gastrointestinal diseases. Increasing fiber intake lowers blood pressure and serum cholesterol levels. Increased intake of soluble fiber improves glycemia and insulin sensitivity in non-diabetic and diabetic individuals. Fiber supplementation in obese individuals significantly enhances weight loss. Increased fiber intake benefits a number of gastrointestinal disorders including the following: gastroesophageal reflux disease, duodenal ulcer, diverticulitis, constipation, and hemorrhoids. Prebiotic fibers appear to enhance immune function. Dietary fiber intake provides similar benefits for children as for adults. The recommended dietary fiber intakes for children and adults are 14 g/1000 kcal. More effective communication and consumer education is required to enhance fiber consumption from foods or supplements.
Because I know people will ask, I have not been on a ketogenic diet “regularly” since about mid- to late-2014. The reasons are too nuanced to describe here, but my deviation is not because I lost confidence in its efficacy. With nearly a decade of clinical experience, I can safely say I was an outlier (in the best sense) with respect to my physiology and response. I was leaner, and more mentally and physically fit during this three year period than during any other period of time as an adult, and my biomarkers were as good as they had ever been. I’ve also seen the benefit of ketogenic diets first-hand on my patients and my own sister, a remarkable story I hope to share one day. But I’ve also been humbled by my inability to explain why some people have suboptimal or even negative responses to NK. I would say, all things considered, my knowledge of ketosis is greater today than when I was writing about it voraciously, but my confidence in my understanding of it, might actually be lower. As the saying goes, the further one goes from shore, the deeper the water gets.
NOTE: Make sure to weigh your ingredients to ensure it rises properly and doesn’t get hallow and gummy. Also, if you do weigh and grind your psyllium and still have a problem, try grinding the psyllium again. We have a batch of psyllium that we ground and didn’t work. Stay really wet. So we ground it again and it works great! Also, if your loaf looks nice and big but then deflates after removed from the oven, try reducing the baking powder to 3 teaspoons.
Glucose is stored in your liver and released as needed for energy. However, after carb intake has been extremely low for one to two days, these glucose stores become depleted. Your liver can make some glucose from amino acids in the protein you eat via a process known as gluconeogenesis, but not nearly enough to meet the needs of your brain, which requires a constant fuel supply.
The secret step in this recipe that takes this carb-free bread from good to great is the separation of the eggs. You’re going to want to separate the yolks and the whites. The reason for this is that we’re going to whip the egg whites until they are fluffy. We’re looking for soft peaks. This will add some volume to the otherwise dense keto bread. Beating the egg whites is the answer to the denseness that comes with making an almond flour bread. I’ve made countless baked goods using almond flour and the main problem I’ve encountered is how dense the finished product is. The fluffy egg whites in unison with the high dosage of baking powder do a good job of getting this loaf nice and fluffy and adding some air pockets into the loaf. This makes for a better tasting bread.
