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.
Metabolic syndrome, also known as Insulin Resistance Syndrome (IRS) and Syndrome X, is a cluster of metabolic and anthropometric traits including glucose intolerance, upper body fat distribution (increased intra-abdominal fat mass), hypertension, dysfibrinolysis, and a dyslipidemia (characterized by high triglycerides, low high-density lipoprotein [HDL] cholesterol, and small dense low-density lipoprotein [LDL] particles).1 Metabolic syndrome constitutes a powerful risk factor complex to identify individuals at increased risk for future Type 2 diabetes and cardiovascular disease (CVD). Insulin resistance and abdominal obesity are two central components of the syndrome and are integrally involved in its pathogenesis. Insulin resistance is a metabolic abnormality in which peripheral tissues exhibit a subnormal biologic response to the glucose-lowering action of insulin. Insulin resistance not only antedates the development of diabetes but is also a major metabolic defect (together with impaired insulin secretion and elevated hepatic glucose production) that maintains hyperglycemia in patients with overt disease. The central role of abdominal adiposity underscores the importance of body fat distribution regarding the metabolic consequences of obesity. Individuals with metabolic syndrome are also more prone to develop other pathologic conditions including polycystic ovary syndrome, non-alcoholic steatohepatitis (NASH), cholesterol gallstones, sleep disorders, and some types of cancer. Thus, metabolic syndrome is responsible for a tremendous burden of human disease and social costs, and nutritional therapy is key to both its prevention and limiting its progression to Type 2 diabetes and CVD.
You can find a mixed bag of studies in rodents; sometimes the ketogenic diet is amazing sometimes it’s terrible. The main reason why is because there are many kinds of ketogenic diets; what fats were used? how processed is the food and what was the method of processing? were these genetically manipulated mice or wild type? were they fed ad lib (to their hearts content), forced fed (hypercaloric) or had their calories restricted?
Have you heard all the buzz about the keto diet and want to know more? Did a friend tell you they’re “in ketosis” and you got interested? Here’s everything you need to know about ketogenic diets and being in ketosis for fat loss, brain function, satiety, and performance. Editor’s Note: This article is being updated … Continue reading The Keto Diet: Next Big Thing or Dangerous Fad?
Hi I made the Easy paleo keto bread 5 ingredients. It was moist, texture was good but it didn’t turn out completely white, more like a pale yellow and the crust was overdone. I opted for honey as my sweetner because this bread is for my nephew who has autism and we want to keep it as natural as possible. I baked the bread exactly at 325 for 40mins uncovered and then another 40mins covered (tent). What could I do next time to achieve a white bread with golden crust?
The ketogenic diet is high-fat and low-carb, and if you pay attention to food and nutrition trends, then you already know that creative recipes for this weight-loss plan are all over social media. If you've gone keto or are thinking of trying it, check out these tasty morning meal ideas to help you stay full, score energy, and leave you feeling satisfied.
Research on cinnamon’s blood sugar-stabilizing powers is a little mixed, and it may not be a wonder spice. But if you’re adding it to an already healthy diet, it may have a subtle benefit. Some studies suggest that cinnamon lowers blood sugar by increasing insulin sensitivity, or making insulin more efficient at moving glucose into cells. Try sprinkling it onto oatmeal or into low-sugar smoothies. Bonus: It tastes delicious!
Lately anecdotal evidence has been building that a ketogenic diet can yield transformative results with respect to weight loss: with people taking to social media to share ‘before and after keto’ photos and to stories of ‘how keto changed my life.’ Despite this, concrete clinical evidence confirming that a ketogenic diet is superior to any other diet that creates a calorie deficit is lacking. At the moment the most accurate statement is that ‘the best diet for you is one you can stick to,” a pattern of eating that maintains a small calorie deficit should, over time, lead to weight loss.
4.) Fill the dough into a loaf tin lined with baking paper. If you don’t use a silicone loaf pan line ALL SIDES with parchment paper so the bread will release easily. Smooth the top, but don’t press down too much – keep as much air in the dough as possible. Bake at 180 Celsius / 350 Fahrenheit for about 45 minutes or until a knife inserted comes out clean!

In ketogenesis, two acetyl-CoA molecules instead condense to form acetoacetyl-CoA via thiolase. Acetoacetyl-CoA momentarily combines with another acetyl-CoA via HMG-CoA synthase to form hydroxy-β-methylglutaryl-CoA. Hydroxy-β-methylglutaryl-CoA form the ketone body acetoacetate via HMG-CoA lyase. Acetoacetate can then reversibly convert to another ketone body—D-β-hydroxybutyrate—via D-β-hydroxybutyrate dehydrogenase. Alternatively, acetoacetate can spontaneously degrade to a third ketone body (acetone) and carbon dioxide, although the process generates much greater concentrations of acetoacetate and D-β-hydroxybutyrate. When blood glucose levels are low, ketone bodies can be exported from the liver to supply crucial energy to the brain.
As will be discussed in the following sections, many of the signaling proteins involved in regulating antioxidant defense also regulate oxidative phosphorylation and fat oxidation. There is abundant evidence (Table 1) showing ketogenic and low-carbohydrate diets to increase expression, content, or activity of many targets of these signaling proteins, further indicating increased oxidative capacity. It is particularly striking that ketogenic or low-carbohydrate diets upregulate expression of proteins associated with each of the five mtETC complexes.
The yeast in this low carb and keto bread ensures a wonderful texture and taste. Now, how much your bread will rise (and fall!) post-bake depends quite a bit on your altitude. But note that you still won’t get that gummy and wet texture here of most low carb breads. Plus, as mentioned, we’re baking at over 7,000 feet (Mexico City here!!), so if we can make this keto sandwich bread work so can you.
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.
Although metabolic syndrome is a serious condition, you can reduce your risks significantly by reducing your weight; increasing your physical activity; eating a heart-healthy diet that's rich in whole grains, fruits, vegetables and fish; and working with your healthcare provider to monitor and manage blood glucose, blood cholesterol, and blood pressure.
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)
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.
I followed the recipe to a tee, used all recommended ingredients. I’ve attempted making it twice, the first time I didn’t have a food processor and that was a complete fail. The second time, today, I bought a food processor and attempted it again. The egg whites were fluffy but never got to stiff peaks… maybe my eggs were too cold? Anyway, I baked for 30 mins, and it wasn’t even golden brown on the top so I didn’t put the foil on time and cooked it another 20 mins. I just pulled it out about 20 mins ago and it is golden brown. However, it is a very moist almost like a banana bread texture. I just popped it back in the oven hoping it will “dry up”. Any recommendations? Do I need to cook for and hour ?
Add yeast and maple syrup (to feed the yeast, see notes) to a large bowl. Heat up water to 105-110°F, and if you don't have a thermometer it should only feel lightly warm to touch. Pour water over yeast mixture, cover bowl with a kitchen towel and allow to rest for 7 minutes. The mixture should be bubbly, if it isn't start again (too cold water won't activate the yeast and too hot will kill it).
Parkinson’s disease (PD) is caused by death of neurons in a region of the brain called the ‘substantia nigra.’ As well as loss of neurons, those that survive accumulate misfolded proteins called “Lewy Bodies,” exhibit increased inflammation and impaired mitochondrial function. PD is most common in individuals over the age of 60 and is primarily characterised by poor control of movement (shaking, rigidity etc). Neuronal death leads to decreased levels of a neurotransmitter called dopamine, which is a key factor in the deterioration of motor function. Current treatments for PD centre on replacing dopamine using a drug called L-DOPA, which is a precursor to dopamine. This drug treats the symptoms of PD but not the underlying cause.
This bread looks amazingly awesome and I will be trying it soon, but with a gluten free psyllium husk brand. I just wanted to point out that J Robb’s Psyllium Husk package declares the presence of WHEAT. Read the label listed on his website. Using his Psyllium Husk would make the bread NOT gluten free. It also states that it has a multitude of other allergens and possibly all of them are in a package at the same time. Just a heads up.
My point here is that the warnings about the ketogenic principles are well taken and well documented. My concern is implications that this is a fad. I don’t use the word diet with my patients and I’m concerned that the principles behind the label and the real results that these readers have commented on might get minimized. I have found it best to encourage patients to read authors like: Stephen Phinney, Jeff Volek, Patricia Daly, and Charles Gant and the be partners with their doctors and check blood work as they move along. I am not for or against the article. If ketogenic principles offer people enduring, satisfying, and cohesive change then why not read about its potential and flexilbity?

One of the foods that people tell us they miss most after going keto is bread. (And cookies or cakes, but you get the idea.) We get it, bread is undeniably comfort food. Growing up, it wasn’t unheard of to eat toast for breakfast, a sandwich for lunch, and maybe even a slice of buttered bread along with dinner. Not only is that ton of carbs, but it’s also a lot of empty calories when we could have been eating real-food alternatives, like this bread made from nutrient-dense ingredients!
