Yeah, odd prescription, I know, but dog owners are more active than non-dog owners. Why? Well…picture those big, brown, sad eyes pleading with you: Pleeeeeeeeeease take me for a walk. Frankly, most of us have a hard time with self-motivation. We’re tired, overworked, and stressed out—but we’re human beings. There’s a root word of humane in there somewhere. Often, we will do for others what we won’t do for ourselves; and pets are the hardest to say no to, because of the whole issue of interspecies communication. You can rationalize with your kid about why you’re too busy to play in the park with her, but your dog isn’t going to take no for an answer.
I’m here to testify about what DR. AFRID did for me. I have been suffering from (HERPES) disease for the past 5 years and had constant pain, especially in my knees. During the first year,I had faith in God that i would be healed someday.This disease started circulating all over my body and i have been taking treatment from my doctor, few weeks ago i came across a testimony of one lady on the internet testifying about a Man called DR.AFRID on how he cured her from herpes disease. And she also gave the email address of this man and advise anybody to contact him for help for any kind of sickness that he would be of help, so I emailed him telling him about my (HERPES) he told me not to worry that i was going to be cured!! Well i never believed it,, well after all the procedures and remedy given to me by this man few weeks later i started experiencing changes all over me as DR. AFRID assured me that i will be cured,after some time i went to my doctor to confirmed if i have be finally healed behold it was TRUE, the test came out negative. So friends my advise is if you have such sickness or any other at all you can contact DR. AFRIA for help CALL/WHATAPPS HIM +2349057260738.
The occurrence of mitohormesis is further supported by the potential for mtROS to simultaneously induce bioenergetic and antioxidant adaptations through a single signaling mediator. As discussed later in this review, this mediator is the transcription factor peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α), and its role in simultaneously inducing bioenergetic and antioxidant adaptations has been demonstrated in several experimental models of mtROS production, including treatments with paraquat and H2O2. Paraquat is an herbicide that is reduced by the mtETC and subsequently initiates mtROS production by reacting with O2 to produce O2•− [74, 75], and H2O2 is a common form of mtROS. Treatment of a fibroblast cell line (10T1/2) with H2O2 has induced expression of both antioxidant enzymes (SOD1, SOD2, and GPx1) and proteins involved in mitochondrial oxidative phosphorylation, all in a manner largely dependent on PGC-1α . Demonstrating the hormetic benefit of this response in a variety of brain cells, overexpression of PGC-1α protected against cell death induced by H2O2 or paraquat treatment, and this occurred in conjunction with changes in gene expression similar to those observed with the 10T1/2 cells . Although the central role of PGC-1α in linking mitochondrial bioenergetics with antioxidant defense appears to not have been thoroughly investigated in vivo, some suggestive evidence does exist. In skeletal muscle of mice treated with paraquat, content of proteins involved in mitochondrial oxidative phosphorylation and uncoupling have been found to increase in conjunction with greater nuclear localization of PGC-1α . Traditional antioxidant proteins were not measured, but, as will be discussed later, the increase in uncoupling proteins can be regarded as an indication of enhanced antioxidant defense based on the potential of these proteins to decrease mtROS production.

In addition to the downstream bioenergetic and antioxidant signaling induced by sirtuins, they directly facilitate ketogenesis and β-oxidation. SIRT1  and SIRT3  deacetylate 3-hydroxy-3-methylglutaryl CoA (HMG CoA) synthase, which is the rate-limiting enzyme for ketogenesis , resulting in increased levels of β-hydroxybutyrate . In addition, SIRT3 deacetylates and increases activity of long-chain acyl-CoA dehydrogenase (LCAD) , which participates in β-oxidation and therefore supports ketogenesis. SIRT3 has a similar influence on medium-chain acyl-CoA dehydrogenase (MCAD) as well . Since sirtuins facilitate ketogenesis, which then facilitates sirtuin activation, nutritional ketosis may promote, to some extent, a feed-forward cycle of sirtuin activity.
By dramatically shifting energy metabolism towards ketogenesis and fatty acid oxidation, ketogenic diets are likely to have a profound effect on mitochondrial function. However, despite the rapidly growing amount of research on ketogenic diets and their effects on various disease states, only a small amount of this research has focused on mitochondrial function or oxidative stress. The well-established increase in fat oxidation induced by a ketogenic diet [7, 8] clearly indicates prominent connection with mitochondrial function and, in turn, oxidative stress and mitohormesis [5, 6, 9]. Therefore, the purpose of this review is to describe the current, but limited, understanding of how ketogenic diets may affect mitochondrial function and resistance to oxidative stress, particularly within the context of extending human healthspan.
A giant, late-night dinner is your blood sugar’s worst enemy. That’s because our bodies become more insulin resistant as the day goes on—so a meal that you eat in the evening will cause a greater spike in blood sugar than a meal you eat in the morning. Because of this, many nutrition experts advise front-loading your meals, or eating bigger meals earlier in the day and having a smaller dinner at least three hours before bed.
Agree with post regarding salt omitted salt, grilled it first time. It definitely reminds me of corn muffins texture. This morning make recipe added 1 T. of swerve brown sugar and dash or cinnamon,nutmeg and chopped walnuts OMG. It was great topped with cream cheese frosting(cream cheese,butter ,vanilla and swerve confection .Thanks can’t wait to try pumpkin spice next time I’m craving carrot cake thanks so much!
Recently, many of my patients have been asking about a ketogenic diet. Is a ketogenic diet safe? Would you recommend it? Despite the recent hype, a ketogenic diet is not something new. In medicine, we have been using it for almost 100 years to treat drug-resistant epilepsy, especially in children. In the 1970s, Dr. Atkins popularized his very-low-carbohydrate diet for weight loss that began with a very strict two-week ketogenic phase. Over the years, other fad diets incorporated a similar approach for weight loss.
Maria, I made your bread using NOW psyllium, it tastes more like a loaf of real bread than anything I’ve tried. It’s lots better than the pricey Low Carb Bread Company loaves that I have been buying on Netrition. I had previously tried a similar recipe that had coconut flour, and even though I added quite a bit of onion powder, the coconut flavor was still distinguishable, and I’m not a fan.
You’ve got a few options here. Erythritol (Lakanto is awesome here), Xylitol (non-corn though to avoid tummy troubles!) and allulose are my top choices (no aftertaste at all!). Pyure is also a good one for muffins and quick breads, particularly if you’re trying to limit your sugar alcohol consumption (it’s added stevia makes it twice as sweet as sugar… i.e. you add half!).
Missing bread on your keto diet? No need. Here you’ll find the most popular keto bread recipes, rated by thousands of people. Take a bite of the famous keto bread, oopsies, seed crackers and mouth watering classics like BLT sandwich, garlic bread, naan and biscuits. Not only are these bread recipes far healthier than regular bread, they’re also ready in a flash!
To get into ketosis without supplementation, you have to keep your insulin levels low. Supplementing with exogenous ketones can help get you into ketosis . However, you won’t have achieved the same beneficial physiological changes as you would have from a well-formulated ketogenic diet or fasting. This is why we at Nutrita don’t recommend exogenous ketones as a substitute for a well-formulated ketogenic diet.
If you divide the dough in 3 you’ll cook the bread for 90 seconds on high, but if you cook it all together you’ll want to do 150 seconds (2 1/2 minutes). Either way, it’ll come out looking pale and spongy (and not very appetizing at all tbh!). But worry not, just wait for it to cool down until just lightly warm (it continues to cook guys!), and then you’ll definitely want to give it a toast to get some texture on.
I’m so glad you love it, Tanya! Yes, $17 sounds like a lot for xanthan gum. I use this one here. Swerve is sweeter than erythritol, so you’d need less of it – I have a conversion chart here. You’re absolutely right about the xanthan gum and texture – it will make the bread more chewy. It will still be more of a “light and fluffy” bread, but definitely less muffin-like with the xanthan gum. I haven’t tried add-ins yet – let me know how it goes if you try!

The concentration of ketone bodies may vary depending on diet, exercise, degree of metabolic adaptation and genetic factors. Ketosis can be induced when a ketogenic diet is followed for more than 3 days. This induced ketosis is sometimes called nutritional ketosis. This table shows the concentrations typically seen under different conditions
Ketosis is a metabolic state in which the liver produces small organic molecules called ketone bodies at “sufficient” levels, which I’ll expand upon later. First, let’s get the semantics correct. The first confusing thing about ketosis is that ketone bodies are not all – technically — ketones, whose structure is shown below. Technically, the term ketone denotes an organic molecule where a carbon atom, sandwiched between 2 other carbon atoms (denoted by R and R’), is double-bonded to an oxygen atom.
I appreciate the great Dr BEN for his healing herbal medicine he prepared for me, after being a sufferer of HSV 1&2 Disease for 2years. it was very surprising how i got cured from Dr BEN herbal medicine, that quickly cleanse my whole body and today after checking myself in the hospital i was found negatives, dear viewers my doctor personally told me that there was no cure for my Disease at first i thought the world has ended for me but as soon as i got reached to Dr BEN herbal medicine, my story was not the same again, i only used Dr BEN herbal medicine for just 3weeks and i was totally cured, no one deserve to suffer for so long,health is wealth my dear viewers no amount of money can cure you except you get the right remedy and be cured completely, today a cure is found and confirm by many others like me, Dr BEN also has other cure for HIV AIDS, DIABETES,HEPATITIS B,CANCER,HEART DISEASE,MIGRAINES,COLD SORES,I am going to keep spreading this good news to the whole world, his email address is:firstname.lastname@example.org or his What app Mobil:+2348078665168
While exercise is a great way to bring down your blood glucose immediately, remember that physical activity should be a part of your lifestyle, not just a tool for producing one good test result. Getting your recommended periodic A1C tests will help you and your doctor determine if your blood glucose control is on target. And when you use your meter to test at home and at work, be sure to look for patterns in the results. This can help you and your diabetes care team tell whether you need to adjust your diet, medications, or both. The most important thing you can do to manage diabetes well is to control your blood glucose, and exercise is a key step toward reaching that goal.
Fantastic! So easy to make. Not sure if I didn’t mix mine well enough, but it had a couple of “air holes” in it after baking. Did not matter…tastes great. I made a grilled cheese out of two of the slices…delicious! I can’t wait to try some of the ideas from the comments: adding herbs and/or spices, adding cinnamon and stevia, etc. Seems the possibilities are endless.

Well… it turned out beautifully. It rose evenly, it was light, fluffy and baked through. It tasted very good, both plain and toasted with butter. I truthfully do not know if I would add the butter the next time I make a loaf because I was so pleased with this version. I will likely reduce the erythritol to 1 tablespoon or less for a more subtle sweetness in the future. This recipe has so many flavour possibilities and I look forward to trying out all of my ideas using this excellent base. It is also good to know that it can be made without the additional fat component. Don’t get me wrong, I am keto and a committed high fat enthusiast but slathering some fat on top of the bread… butter, pâté, nut butter… will work just fine for me.
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.
Your first dietary step towards more balanced blood sugar: ditching (most of) the packaged foods and focusing on high-quality whole foods such as vegetables, fruits, whole grains, beans, nuts, seeds, and quality meats and fish. Many processed foods are high in sugar, refined grains and carbs, and artificial ingredients and flavorings, while being low in blood-sugar-stabilizing fiber and protein. Of course, it’s also important to be realistic. You’re probably not going to be able to nix packaged foods completely, so just make a point to select those that are made from mostly whole-food ingredients, like a bar that lists just nuts, seeds, and dried fruit on its label.
Glycogen influences AMPK activity by binding to a glycogen binding domain on the β regulatory subunit of AMPK [205, 206]. In human and rodent skeletal muscle, AMPK activity is lower when glycogen is bound to this domain [207, 208] and higher when muscle is depleted of glycogen [209–212]. In direct contrast to the effect of AMP and ADP, glycogen inhibits the phosphorylation of AMPK by upstream kinases such as LKB1 . Although muscle glycogen concentration has recently been demonstrated to be similar in ultra-endurance athletes regardless of a ketogenic or high-carbohydrate diet , concentrations generally decrease in response to dietary carbohydrate restriction [156, 166, 173, 214–221]. Furthermore, the long-term adaptations to nutritional ketosis that may enable some athletes to replenish glycogen at a normal rate may not apply to less physically active individuals.
Moving more . Even if you’ve never exercised before, you can start now and markedly reduce your risks. Even moderate amounts of activity will make a difference with heart markers. Walking is a good starter plan for many people. “I tell my patients to get an activity tracker,” Ndumele says. “Aim for 5,000 steps a day and work up to at least 10,000 steps a day.” Talk to your doctor to get the go-ahead on the types of workouts you want to try.

the abnormal accumulation of ketones in the body as a result of excessive breakdown of fats caused by a deficiency or inadequate use of carbohydrates. Fatty acids are metabolized instead, and the end products, ketones, begin to accumulate. This condition is seen in starvation, occasionally in pregnancy if the intake of protein and carbohydrates is inadequate, and most frequently in diabetes mellitus. It is characterized by ketonuria, loss of potassium in the urine, and a fruity odor of acetone on the breath. Untreated, ketosis may progress to ketoacidosis, coma, and death. See also diabetes mellitus, ketoacidosis, starvation. ketotic, adj.
Acetoacetate diester did not improve performance37: a different ketone ester to that used by Cox et al (an acetoacetate diester) decreased cycling performance by 2% given before a 50’ cycling race. Reasons for the difference in findings could be: this ketone ester drink was given along with a can of diet cola 30 mins before exercise and caused GI upset in many athletes. Delivering acetoacetate causes the muscle cells to become more ‘oxidised,’ which is a less favourable state for ATP production. Risk of some gastrointestinal upset with all ketone supplements. The dose, tonicity, time taken before competition and overall volume of a ketone drink will affect how easy it is to tolerate. Many athletes take ketone supplements without side effects, however there are differences between individuals, so practice with ketone supplements in training is advisable to ensure they don’t experience any GI side effects in competition. Geoff Woo discussed this study in a blog post.

Excess abdominal fat leads to excess free fatty acids in the portal vein, increasing fat accumulation in the liver. Fat also accumulates in muscle cells. Insulin resistance develops, with hyperinsulinemia. Glucose metabolism is impaired, and dyslipidemias and hypertension develop. Serum uric acid levels are typically elevated (increasing risk of gout), and a prothrombotic state (with increased levels of fibrinogen and plasminogen activator inhibitor I) and an inflammatory state develop.

I never believed i would be healed someday from Diabetes type 2.This disease started circulating all over my body and i have been taking treatment from my doctor, few weeks ago i came on search on the internet if i could get any information concerning the prevention of this disease, on my search i saw a testimony of someone who has been healed from (Diabetes 2 and Cancer) by this Man DR iyoriobhe 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 wrote to his mail telling him about my (Diabetes) he told me not to worry that i was going to be cured!! hmm i never believed it,, well after all the procedures and remedy given to me by this man few weeks later i started experiencing changes all over me as DR iyoriobhe assured me that i have cured,after some time i went to my Dr to confirmed if i have be finally healed, behold! it was TRUE, So friends my advise is if you have such sickness or any other at all you can email DR iyoriobhe on : doctoriyoriobhe4@gmail. com OR whatsapp him ,+1 606-654-3154 .
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-
In order to best investigate the efficiency of different fuels, one needs a closed system, where the substrate conditions can be changed and the oxygen consumption and work done can be accurately measured. Isolated (ex-vivo) animal hearts are the best model to study these variables, as it is easy to manipulate the fuel provided (i.e glucose, ketones), to measure the oxygen use and also the amount of work (how much fluid is pumped).
Clinical results suggest both direct and indirect actions of ketones via modifications of various hunger-related hormones concentrations. While it’s not completely clear how ketosis reduces appetite, studies have found that ketosis is effective at lowering food intake and regulating appetite by altering levels of the hunger hormones including cholecystokinin (CCK) and ghrelin. At the same, ketone bodies seem to affect the hypothalamus region in the brain, positively impact leptin signals, and avoid slowing down the metabolism like most other diets do. (5)

Increasing dietary fiber, especially insoluble fiber from cereal and grains, is associated with a reduced risk of diabetes and has been shown to reduce fasting blood glucose and modestly lower HbA1c in people with type 2 diabetes (Martin, J Nutr 2008; Post,J Am Board Fam Med 2012). In people with type 1 diabetes, 50 grams of dietary fiber per day has been shown to significantly improve blood sugar control and reduce hypoglycemic events (Giacco, Diabetes Care 2000). The American Dietetic Association states that "diets providing 30 to 50 g fiber per day from whole food sources consistently produce lower serum glucose levels compared to a low-fiber diet. Fiber supplements providing doses of 10 to 29 g/day may have some benefit in terms of glycemic control." (Slavin, J Am Diet Assoc 2008). Although ConsumerLab.com has not tested fiber products, we have produced a webinar about that provides more information.
I still don’t know the right words to express my gratitude to the Great Dr. Maggi. After been diagnosed of HERPES SIMPLEX VIRUS in 2014, i was given so many health prescription and advice with no improvement, I totally lost hope, until i found testimonies of Great Dr. Maggi in an online research and on Facebook, Like anybody would be, I was very skeptical about contacting him, but i later did and he opened up to me and told me what was involved and he started the remedies for my health. Thank God, i was cured from herpes by the herbal medication I received from him. I never thought that herpes can be cured, from the bottom of my heart I’m truly grateful,i pray you have long life so you can help many more people on earth with your herbal medical support, You can Email him via his email Maggiherbalcenter@gmail.com or for easy and fast communication call him on +1(662) 967-1783 you can also add him on whats-app with this number , +1(312)767-3460. one thing i love most about DR Maggi is honestly, and he is very polite with his customers, everything he told me was what he did, and his herbal medicine are very affordable.or see more on his webs:drmaggiherbalcenter.webs.com
Hi there, how many slices you get really depends on the kind of loaf pan you use. I find I get around 20 slices for a bread made in the regular loaf pan (though with this recipe they will be rectangular rather than square) and 12-14 slices using a small loaf pan as described in the post. That’s why I decided to state a portion size – 12 per bread. 1 portion = 0.6 net carbs
In general, a person with metabolic syndrome is twice as likely to develop IHD and five times as likely to develop diabetes as someone without it. The probability of developing metabolic syndrome is also closely linked to a lack of physical activity and the fact of being overweight/obese. Other causes include insulin resistance, ethnicity (often Asian), family history, older age and other factors (Box 23.1). Associated diseases and signs may be raised uric acid levels, hepatic steatosis, haemochromatosis and acanthosis nigricans. Metabolic syndrome may be associated with inflammatory periodontal disease.
Because the population of the U.S. is aging, and because metabolic syndrome is more likely the older you are, the American Heart Association (AHA) has estimated that metabolic syndrome soon will become the main risk factor for cardiovascular disease, ahead of cigarette smoking. Experts also think that increasing rates of obesity are related to the increasing rates of metabolic syndrome.
The ketogenic diet can compromise high intensity sprint performance: High intensity exercise performance is heavily reliant on the ability to produce energy via anaerobic respiration (glycolysis), which requires carbohydrate as a substrate. Following a ketogenic diet causes a decrease in the amount/activity of the enzymes in the glycolysis pathway that decreases the rate that the pathway can proceed24. This could explain the decrease in anaerobic sprint performance consistently seen with athletes following a ketogenic diet 25 ,23.
It is interesting to note that the KB are capable of producing more energy than glucose due to the changes in mitochondrial ATP production induced by KB (Kashiwaya et al., 1994; Sato et al., 1995; Veech, 2004). During fasting or KD glycaemia, though reduced, remains within physiological levels (Seyfried and Mukherjee, 2005; Paoli et al., 2011). This euglycemic response to extreme conditions comes from two main sources: glucogenic amino acids and glycerol liberated via lysis from triglycerides (Vazquez and Kazi, 1994; Veldhorst et al., 2009). Glucogenic amino acids (neoglucogenesis from amino acids) are more important during the earlier phases of KD, while the glycerol becomes fundamental as the days go by. Thus, the glucose derived from glycerol (released from triglyceride hydrolysis) rises from 16% during a KD to 60% after a few days of complete fasting (Vazquez and Kazi, 1994). According to Bortz (1972) 38% of the new glucose formed from protein and glycerol is derived from glycerol in the lean while 79% in the obese (Bortz et al., 1972). It is important to note that during physiological ketosis (fast or very low calorie ketogenic diets) ketonemia reaches maximum levels of 7–8 mmol/L with no change in blood pH, while in uncontrolled diabetic ketoacidosis blood concentration of KBs can exceed 20 mmol/L with a consequent lowering of blood pH (Robinson and Williamson, 1980; Cahill, 2006) (Table (Table11).
Nutritional ketosis may initiate bioenergetic and mitohormetic signaling through an increase in catecholamines or adiponectin, a decrease in insulin or glycogen, or an increase in β-oxidation that leads to an increase in mitochondrial reactive oxygen species (mtROS) or NAD+. This leads to further signaling involving AMP-activated protein kinase (AMPK), silent mating type information regulation 2 homologue 1 (SIRT1), peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α), forkhead box O 3a (FOXO3a), and nuclear factor erythroid-derived 2-like 2 (NFE2L2), ultimately leading to transcription of genes related to oxidative capacity, mitochondrial uncoupling, and antioxidant defense. These adaptations collectively contribute to resistance against oxidative stress. Other proteins involved include liver kinase B1 (LKB1), which activates AMPK; nicotinamide phosphoribosyltransferase (NAMPT), which facilitates SIRT1 activation through NAD+ synthesis; and nuclear respiratory factors 1 and 2 (NRF-1 and NRF-2) and mitochondrial transcription factor A (TFAM), which promote mitochondrial biogenesis.
I think next time I will either use less psyllium or less egg. I had to halve the recipe and I used a bit more egg and water by accident. Next time I’ll try it with coconut flour since I think as a very “dry” flour it works best with flours/meals that are very “wet” like flax meal and psyllium. They cancel each other out in the end it seems. I’ll also bake it a bit longer because the crust is yummy!
In addition to the seaweed and glycogen carbohydrates mentioned above, the Inuit can access many plant sources. The stomach contents of caribou contain a large quantity of partially digested lichens and plants, which the Inuit once considered a delicacy. They also harvested reindeer moss and other lichens directly. The extended daylight of the arctic summer led to a profusion of plant life, and they harvested plant parts including berries, roots and stems, as well as mushrooms. They preserved some gathered plant life to eat during winter, often by dipping it in seal fat.
Although resting skeletal muscle is less metabolically active than the heart, kidneys, brain, or liver, it rivals even the brain in being the body's most metabolically demanding tissue when considered relative to total tissue mass . Physical activity can greatly increase this demand, making exercise a practical and powerful way to induce bioenergetic adaptations.
The advice on carbohydrate-rich foods, for example, may make a person with type 2 diabetes require initiation of treatment with insulin injections. One single year’s insulin-consumption may easily cost $2000 or more. Multiply this number by the 422 million diagnosed people diabetes worldwide and you will see the enormous economical interests in this.
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.
First I tried using coconut flour only. The batter was very thick and pasty and the resulting bread was very firm and dry, like a really dry biscuit. It did, however, keep its shape well and toasted up evenly golden-brown in a skillet with oil. I thought about trying again with more liquid, but that wouldn’t solve its fatal flaw: the strong, overwhelming coconut flavor. Even chicken and sun-dried tomato pesto could barely cover it up.
