BHB, in addition to being an important energy substrate, is also a signaling molecule [100–102]. Although not induced through mtROS, BHB inhibits class I and II histone deacetylases (HDACs) in a dose-dependent manner, resulting in greater histone acetylation regardless of whether BHB is elevated through fasting, caloric restriction, or infusion . This inhibition is associated with increased expression of forkhead box O (FOXO) 3a and metallothionein II and increased protein content of FOXO3a, SOD2, and catalase . Consistent with these changes, the kidneys of mice with elevated blood BHB concentrations (∼1.2 mM) were protected from paraquat-induced (50 mg/kg) oxidative damage to proteins and lipids, which was indicated by lower levels of protein carbonyls, 4-HNE, and lipid peroxides . Upregulation of antioxidant defense by BHB-induced HDAC inhibition also appears to be the mechanism through which exogenous BHB extends lifespan in C. elegans . The dependence of this response on FOXO3a, NFE2L2, and several bioenergetic signaling proteins that influence the activities of these two transcription factors  is indicative of the overlap between bioenergetics and antioxidant defense that is characteristic of mitohormesis.
Back in the really old days (like in the Paleolithic), life had some challenges. Like saber-tooth tigers. What happened when your ancient ancestors encountered a saber-tooth cat? I imagine they threw their hands up in the air, screamed, and ran like hell. To assist in the running like hell, their bodies would dump sugar into their blood for extra energy. To this day, our bodies still do that. The problem is that the modern saber-tooth tiger is the overdue electric bill, the dropped cell phone call, the dinnertime telemarketer, and the annoying neighbor. You can’t run away from any of these tigers. The extra sugar just sits in your body. But you can learn to defeat this ancient biological fight-or-flight response by learning how to relax. You’ll need to make time for you. It might be a warm bubble bath in the evening, a good book at lunch, aromatherapy candles, or even kickboxing. Take that, saber-tooth tiger. Bam!
Dr. Campos, it is unfortunate that you retain the medical community’s negative stance on the ketogenic diet, probably picked up in medical school when you studied ketoacidosis, in the midst of an obesity and type II diabetes epidemic that is growing every year, especially among populations who will never see the Harvard Health Letter. The medical community has failed in reversing this trend, especially among children, and the public is picking up the tab, in the form of higher health insurance premiums to treat chronic metabolic diseases which doctors cannot cure. The ketogenic diet does not bid its adherents to eat unhealthy processed meats, and the green leafy vegetables that it emphasizes are important in a number of nutritional deficiencies. People lose weight on the ketogenic diet, they lose their craving for sugar, they feel more satiety, they may become less depressed, their insulin receptors sensitivity is improved, and these are all the good outcomes you fail to mention. There is a growing body of research which demonstrates the neuroprotective effects of the ketogenic diet to slow cancer progression, as well as diseases like Parkinson’s and Alzheimer’s, for which there are no effective medical treatments. Please respect your patients by providing them with evidence-based medical outcomes, not opinions.
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.
It’s a habit to enjoy a brie cheese for desert instead of a piece of chocolate cake but each are favored deserts in France. I’m personally more satisfied after a 350 calorie sized wedge of brie than the same number of calories of cake.. which will give me sugar crash and .. really I’d like two slices of cake(I’ve got a sweet tooth that once I get going it wants to keep being fed)

The longest studies/follow-ups for ketogenic diets are about 10 years long and have shown it to be safe [3, 4, 5, 6]. Studies that carefully keep people in metabolic wards to strictly monitor food intake and biomarkers are always short because they are very costly and laborious. Moreover, most participants are not able or willing to participate for a long time in a study that supervises food intake around the clock. For these reasons, these kinds of studies are always of short duration, a few weeks maximum.
Weigh your ingredients. This will forever be a staple recommendation for any sort of gluten free baking here at gnom-gnom. As aside from leading to less dirty dishes, it will ensure consistent results time and time again. Remember that gluten free (and particularly keto) baking is notoriously finicky, and measuring by cups is anything but accurate. And if you don’t own a baking scale, measure with cups by dropping the ingredients onto them rather than scooping them out (which often leads to overpacking).
When you eat out at a nice place, what comes first? Oh, right. The so-perky-you-want-to-strangle-her girl named Brittany whose pleasure it is to serve you today. But I was talking about the meal itself. Most non-fast-food meals start out with a good salad. What could be healthier? Salads are generally low in both calories and carbohydrates. That means they are good for controlling blood sugar and controlling waistline expansion. An added bonus: if you get filled up with salad, you’ll be less hungry when it comes to the rest of the meal—so you’ll eat less of the stuff that’s “bad” for your blood sugar log. Eating less of that other stuff will help you with Tip Number 4.
In sheep, ketosis, evidenced by hyperketonemia with beta-hydroxybutyrate in blood over 0.7 mmol/L, occurs in pregnancy toxemia. This may develop in late pregnancy in ewes bearing multiple fetuses, and is associated with the considerable glucose demands of the conceptuses. In ruminants, because most glucose in the digestive tract is metabolized by rumen organisms, glucose must be supplied by gluconeogenesis, for which propionate (produced by rumen bacteria and absorbed across the rumen wall) is normally the principal substrate in sheep, with other gluconeogenic substrates increasing in importance when glucose demand is high or propionate is limited. Pregnancy toxemia is most likely to occur in late pregnancy because most fetal growth (and hence most glucose demand) occurs in the final weeks of gestation; it may be triggered by insufficient feed energy intake (anorexia due to weather conditions, stress or other causes), necessitating reliance on hydrolysis of stored triglyceride, with the glycerol moiety being used in gluconeogenesis and the fatty acid moieties being subject to oxidation, producing ketone bodies. Among ewes with pregnancy toxemia, beta-hydroxybutyrate in blood tends to be higher in those that die than in survivors. Prompt recovery may occur with natural parturition, Caesarean section or induced abortion. Prevention (through appropriate feeding and other management) is more effective than treatment of advanced stages of ovine ketosis.
Thanks for this article. I just started a Keto diet so found it appropriate to my current lifestyle. Though I don’t believe your bottom line is strong enough since you simply stating that the diet is “hard to follow” and food is “notoriously unhealthy” without evidence going deeper into why those “notoriously unhealthy” foods are worse than keeping carbohydrate-heavy food that are addictive and give the body a quick sugar high for energy. I believe “hard to follow” is your opinion only, since acceptable Keto foods are found at all restaurants easily and also all grocery stores. All the foods you mention: “rich in very colorful fruits and vegetables, lean meats, fish, whole grains, nuts, seeds, olive oil, and lots of water” are all Keto-friendly. Many people have been on a Keto-diet for years. A healthy lifestyle is a healthy mindset change and making right choices – it’s not going to be easy.

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!
I read through aaaaallllll the comments for research before I made this bread, one thing I noticed when making your protein buns was – when I used 2 teaspoons of baking powder they deflated when exiting the oven. When I reduced the BP to 1.5 teaspoons, they turned out fine. I made two batches with 2 tsp of BP – they turned out like raisins, and 2 batches with 1.5 tsp of BP and they turned out fine. No one posting mentioned adjusting the baking powder – perhaps that would help in this recipe since deflating is a problem, maybe there is too much chemical loft for the non-gluten structure to handle?
Although the first formal definition of metabolic syndrome entered medical textbooks not so long ago (1998), it is as widespread as pimples and the common cold . According to the American Heart Association, 47 million Americans have it. That's almost a staggering one out of every six people. The syndrome runs in families and is more common among African-Americans, Hispanics, Asians, and Native Americans. The risks of developing metabolic syndrome increases as you age.
Natural herbs have cure so many illness that drugs and injection can’t cure.I have seen the great importance of natural herbs and the wonderful works they have done in peoples lives.I read people’s testimonies on line on how they were cured of herpes,HIV, diabetics etc by Dr Akhigbe.herbal medicines,so I decided to contact because I know nature has the power to heal anything.I was diagnosed with HIV for the past 7 year but Dr Akhigbe cured me with his herpes and I referred my aunt and her husband to him. Immediately because they where both suffering from herpes but to God be the glory, they were cured too. I know is hard to believe but am a living testimony. There is no harm trying herbs. He is also good in curing diabetes,cancer,asthman,diarrhea,hiv/aids,impotence and other virus. Contact Dr Akhigbe on phone/WhatsApp no: +2348142454860 or email him on..email@example.com
The most common reason that any bread falls is that it needed to bake for longer. That being said, I’ll be perfectly honest – sometimes this keto bread recipe falls anyway, even despite doing everything else right. Fortunately this isn’t a huge deal because it still tastes delicious – IF you baked it for long enough and the center is cooked through.

The goal of the ketogenic diet is to keep you in this fat-burning metabolic state of ketosis. This is achieved by following a very low-carbohydrate, high-fat diet that includes only moderate amounts of protein. Foods like bread, cereal, processed snacks and sugary drinks are therefore off the table, while fattier foods like butter, grass-fed beef, fish and also non-starchy veggies take center stage, providing the majority of daily calories (as much as 70–80 percent).
Bailey, We’re so happy to hear you enjoyed this recipe! Regarding having bread fall, did you cook it for the full amount of time the recipe calls for, and did you cover the top with foil for the last 15 minutes? If so, there might be an issue with your oven’s calibration (you can get an inexpensive oven thermometer to check this). Another tip is to let your eggs come to room temperature first. Another factor is the altitude at which you’re baking; if you’re at high altitude, you might need to slightly adjust the oven temperature and bake time. The other thing to remember is that there will usually be a little bit of fall to most keto breads (in fact, every keto bread we’ve ever made) because keto flours lack gluten and are naturally quite dense; however, you can see in the photos, we still got a good rise on this loaf. I hope these tips help!
