Admittedly, I started my journey on this path in 2009, with a deep dive into ketosis in the Spring of 2011, but it seemed so obscure! (For a timeline of what I did, I think I covered it somewhere in this talk…yes I’m too lazy to actually confirm this by skimming through it.) All told I spent approximately 3 years in the strictest state of nutritional ketosis (NK) with one very memorable deviation when I had 6 or 7 full-sized and upsettingly decadent desserts circa September 2013. I believe the diet helped me transition from metabolic syndrome to metabolic health and I certainly thought it could benefit other people. This nutritional state could gain some steam, I thought.
Further indicating that ketones influence mtROS production through alteration of electron transport, treatment of rat hippocampal slices with BHB + ACA (1 mM each) prevented the increase in mtROS and mitigated the decrease in ATP production that otherwise result from inhibition of mtETC complex I with rotenone [111]. In mitochondria isolated from the brains of mice injected with BHB, although inhibition of complex I with rotenone and 1-methyl-4-phenylpyridinium increased rather than decreased mtROS production, the BHB treatment prevented the decrease in O2 consumption caused by inhibition of complex I, and this occurred independently of uncoupling [112]. Consistent with the results from hippocampal brain slices, the BHB treatment also mitigated the decrease in ATP production caused by complex I inhibition [112]. These effects were prevented by inhibition of complex II with 3-nitropropionic acid or malonate, indicating that BHB primarily influences mitochondrial respiration at complex II [112], which is consistent with ketolysis increasing formation of succinate and FADH2. However, in mutated cells prone to complex I disassembly and an associated severe decrease in complex I activity, treatment with BHB + ACA (5 mM each) increased both the assembly and activity of complex I [113], indicating that ketones somehow promote repair of complex I damage and may therefore influence mitochondrial respiration at more than one site.
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 made it tonight and use a mini loaf pan. It came out delicious. I used the 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.
Version two was almond flour only. Right away I could tell the recipe would need some modifications. Almond flour doesn’t soak up nearly as much liquid as coconut flour, resulting in a very soupy batter. I added two more tablespoons of almond flour, which was double the amount of coconut flour, and it still wasn’t nearly as thick. After its short stint in the microwave, this bread turned out very moist, soft, and rather flimsy, but was pleasantly bland enough to go with any filling I wanted.
Maria – Love this recipe – took me 4 times before I got it how I wanted it and I add sesame seeds. Then I slice really really thin – about 1/2 cm then dry all the slices in the oven ready for toasting. However, right now I can only find baking powder with vanilla. Can I sub baking soda which together with the vinegar should work but how much? Can you help please?
I used the egg white powder with the recommended amount of water on the egg white can in addition to the 12 oz. of water called for in the recipe. The bread tastes good, but is fairly dense. I didn’t have many eggs and wanted to try the recipe, but I think next time I’ll use fresh egg whites. I’ll also have to figure out what to do with the leftover yolks.

Scheme of orexigenic and anorexigenic effects of ketosis. The picture is highly schematic. For more details please see the text. AMPK, AMP-activated protein kinase; CCK, cholecystokinin; GABA, gamma-aminobutyric acid; BHB, β-hydroxybutyric acid; FFA, free fatty acids; ROS, reactive oxygen species; NPY, neuropeptide Y; AgRP, agouti gene-related protein.
Target organ damage occurs through multiple mechanisms in metabolic syndrome. The individual diseases leading to metabolic syndrome produce adverse clinical consequences. For example, hypertension in metabolic syndrome causes left ventricular hypertrophy, progressive peripheral arterial disease, and renal dysfunction. [12] However, the cumulative risk for metabolic syndrome appears to cause microvascular dysfunction, which further amplifies insulin resistance and promotes hypertension. [13]

Conversely, the term “ketone bodies” refers to 3 very specific molecules: acetone, acetoacetone (or acetoacetic acid), and beta-hydroxybutyrate (or beta-hydroxybutyric acid), shown below, of which only 2 are technically ketones.  (The reason beta-hydroxybutyrate, or B-OHB, is not technically a ketone is that the carbon double-bonded to the oxygen is bonded to an –OH group on one side, technically making B-OHB a carboxylic acid for anyone keeping score.)

Your minimally processed diet should be heavy in non-starchy, fiber-rich vegetables and (to a slightly lesser extent) fiber-rich fruit and whole grains. That’s because fiber slows down the digestion of carbohydrates and the absorption of sugar, which means you experience a more gradual rise in blood sugar levels after meals. Fiber has also been associated with a reduced risk of obesity, heart disease, and diabetes. Good sources of fiber include leafy greens, brussels sprouts, broccoli, artichokes, raspberries, pears, beans, lentils, peas, avocados, pumpkin seeds, and oatmeal.
Is there any way you can post at the beginning of a recipe: NOT for weight loss. I have tried a few recipes before reading the comments below, made it, then saw it was a no no for weight loss. Thanks! I made your pita bread too and it rocks. I am waiting for this amazing bread to come out of the over right now. I am worried about eating now though. Too many carbs for weight loss?
In low carb and keto baking, we’re concerned with two things: 1) keeping carbs low, and 2) still achieving a baked good that has great flavor and texture (because if we can’t gag it down there’s just no point, right? Lol). Low carb bread recipes are usually gluten free and grain free (although we’ve seen a couple that use oat fiber), but then the challenge is to get creative to get the right combination of ingredients to yield something that rises properly and tastes good.
