I read through most of the comments and deglazed the instant pot after cooking the bacon, laid the chicken breasts in the pot so there was no stacking, cut softened cream cheese into cubes and dropped them in, sprinkled seasonings over everything. After pressure cooking for 15 minutes, I did the manual release (smelled so good), took off the lid, and…the chicken isn’t even close to being cooked all the way through! It wasn’t frozen. What happened?
Once inside the mitochondrion, the dominant way that the bound fatty acids are used as fuel in cells is through β-oxidation, which cleaves two carbons off of the acyl-CoA molecule in every cycle to form acetyl-CoA. Acetyl-CoA enters the citric acid cycle, where it undergoes an aldol condensation with oxaloacetate to form citric acid; citric acid then enters the tricarboxylic acid cycle (TCA), which harvests a very high energy yield per carbon in the original fatty acid.
The difference between ketosis and ketoacidosis is the level of ketones in the blood. Ketosis is a physiological adaptation to a low carbohydrate environment like fasting or a ketogenic diet. There are situations (such as treatment-resistant epilepsy) where ketosis can be beneficial to health. Ketoacidosis is an acute life-threatening state requiring prompt medical intervention; its most common form is diabetic ketoacidosis where both glucose and ketone levels are significantly elevated.
The gut-brain link is important not only for the hormones produced by the gut, but also for the long-term body weight regulation. Studies in mice indicate that the gut microbiome influences both sides of the energy balance by contributing to nutrient absorption and regulating host genes that affect adiposity [however there are conflicting reports (Parks et al., 2013; Schele et al., 2013)]. However, it remains uncertain just how important gut microbiota are for nutrient absorption in humans. A cohort study has demonstrated that the nutrient load is a key variable that can influence the gut/fecal bacterial content over short time frames. Furthermore, the observed associations between gut microbes and nutrient absorption indicates a possible role of the human gut microbiota in the regulation of the nutrient intake and utilization (Jumpertz et al., 2011).
Hi, I'm Amanda. I’ve been cooking primal keto and lactopaleo recipes for over a decade, and have developed recipes for top nutrition coaches and ketogenic meal subscription boxes. I'm the author of Keto Life (a guide) and the best-selling Wicked Good Ketogenic Diet Cookbook (a cookbook). Ever heard the phrase,"never trust a skinny chef"? Well, consider me super trustworthy. I will probably never be "skinny," and that’s OK because I’m not here to teach you how to lose weight, my goal is to provide you with awesome recipes. I absolutely adore the ketogenic lifestyle, and it has helped me overcome a number of health issues. I hope my recipes help you do the same, while eatin’ good!
Over the years the ketogenic diet has gained popularity as an accelerated weight loss diet. From Atkins to paleo; low carbohydrate diets have consistently remained the top successful diets used for weight loss. What most do not realize is that a ketogenic diet was first utilized in preventing and mitigating seizures particularly in pediatric patients.

Journal of the Marine Research Institute. 12 (2). ISSN 0484-9019. Retrieved 2014-04-25. The significant levels of carbohydrate, probably mostly in the form of glycogen, in both blubber and muscle, may represent an instant form of energy for diving via anaerobic glycolysis.
When glucose levels are low, especially over time, most cells will switch to using ketone bodies for fuel. Ketones allow cells to be metabolically flexible, so to speak. Even the brain and nerve cells, which are heavily dependent on glucose can utilize ketone bodies for fuel. This ability of most normal cells to use ketones when glucose is unavailable indicates that their cellular mitochondria are healthy and functioning properly.
Many questions about the role of such an important intermediate of lipid metabolism remains unanswered, e.g., the role of BHB in food control. For example, whether or not BHB could act as a satiety signal in the brain, considering its role in energy supply to CNS. We have to consider that the effects of KBs on hunger reduction can only be seen after many days following fasting or KD initiation (Paoli et al., 2010); this is consistent with the abovementioned threshold of brain utilization of KB as an energy source, i.e., 4 mmol/L (Veech, 2004), which is close to the Km for the monocarboxylate transporter (Leino et al., 2001). During the first days of fasting or KD there is a rise of BHB and adiponectin concentrations (Halberg et al., 2005). One of the putative causes of hunger in starved humans may be due—together with other causes—to adiponectin. When adiponectin binds to its receptor AdipoR1, AMP-activated protein kinase (AMPK) is phosphorylated in the ARC of the hypothalamus (Valassi et al., 2008). The increase of AMPK activity in the hypothalamus may increase food intake and hepatic glucose output in mice while the decrease seems to reduce food intake (Zhang et al., 2009). KDs can also act similarly to a caloric restriction on AMPK (Newman and Verdin, 2014). Interestingly, AMPK seems to have opposing actions on the liver, muscle tissues and the brain: in liver and muscle AMPK activation increases FA oxidation by decreasing malonyl-CoA concentrations (Malonyl-CoA is the first intermediate in the lipogenic pathway and is also an inhibitor of carnitine palmitoyltransferase-1 (CPT-1). CPT-1 activity can be limiting for FA oxidation), through the inactivation of the acetyl-CoA carboxylase 1 (ACC1). AMPK can also increase the activity of malonyl-CoA decarboxylase (MCD), which enhances the decrease of malonyl-CoA levels.
First, decide if you need to check ketones. Amy Berger of Tuit Nutrition has a great post here to help you decide. If, after reading that, you still want to check your ketone levels, there are several ways to check them. You can buy Bayer ketone stix, and check the levels of ketones in your urine. Or you can use a blood ketone meter. The Precision Xtra has been the one to use until just recently. The problem is that this meter is hard to find, as the manufacturer Abbott keeps changing the name. The strips are even harder to find and buy.

This low-carb chicken pad thai is one of the best keto recipes for replacing Asian takeout. It’s got all of the flavors that come with normal pad thai, like ginger, crushed peanuts, tamari and chicken, but all served up on spiralized zucchini instead of carb-heavy noodles. Best of all, you’ll have this keto chicken recipe on the table in just 30 minutes.
It is true that, "The liver will make ketones from body fat, the fat you EAT, and from alcohol --- the ketone strips have no way of distinguishing the source of the ketones. So, if you test every day after dinner, and dinner usually contains a lot of fat, then you may very well test for large amounts of ketones all the time."This is why we recommend testing at the same time every day. The morning, before breakfast, is the best time because it will reflect what your body is doing, and not the previous meal. Unless someone tests negative in the morning, then we will recommend testing before bed.
My name is Kevin. My life changed when I realized that healthy living is truly a lifelong journey, mainly won by having a well-balanced diet and enjoying adequate exercise. By experimenting in the kitchen and openly sharing my meals, I learned that healthy eating is hardly boring and that by making a few adjustments, I could design a diet that could help me achieve my personal fitness goals. Our bodies are built in the kitchen and sculpted in the gym.
What a great post. I thought i would add about the selection of food you eat on keto and that everyone is different. Some food gives you energy and some doesnt, this varies person to person. I started and quit keto 3 times before i managed to find my balance. The first few times it made be poorly, from the shock of diet change. However, you can wean yourself into the diet which i did the last time when i had the most success.
Checking your ketone level is one way to know if you’re in ketosis. This metabolic state usually kicks in after three or four days of restricting your carbohydrate intake or going through periods of intermittent fasting. You don’t have to visit a doctor to measure your level. Pick up a ketone urine test from a nearby drug store, or use a blood sugar meter that’s capable of measuring ketones.
Whether ketosis is taking place can be checked by using special urine test strips such as Ketostix. The strips have a small pad on the end, which the user dips in a fresh urine specimen. Within seconds, the strip changes color to indicate the level of acetoacetate ketone bodies, which reflects the degree of ketonuria, which, in turn, gives a rough estimate of the level of hyperketonemia in the body (see table below). Alternatively, some products targeted to diabetics such as the Abbott Precision Xtra or the Nova Max can be used to take a blood sample and measure the β-hydroxybutyrate ketone levels directly. Normal serum reference ranges for ketone bodies are 0.5–3.0 mg/dL, equivalent to 0.05–0.29 mmol/L.

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).
You've likely heard horror stories of what competitors feel like when they cut carbs low, or when the average bro talks about going keto. However, the odds are that those people were not actually in nutritional ketosis, or more importantly, following a well-formulated ketogenic diet. Yes, you may experience some fogginess and discomfort, but it doesn't have to be intense if you handle it right.
It feels like everyone is talking about the keto diet — the high-fat, low-carb eating plan that promises to turn your body into a fat-burning machine. For that reason, keto has surged in popularity over the past year as a lose-weight-fast strategy. Thank Hollywood A-listers and professional athletes like Halle Berry, Adriana Lima, and Tim Tebow who’ve publicly touted the diet’s benefits, from shedding weight to slowing down aging. Here’s everything you need to know about going keto — and how to do it the Bulletproof way.
Some Inuit consume as much as 15–20% of their calories from carbohydrates, largely from the glycogen found in raw meats. Furthermore, the blubber, organs, muscle and skin of the diving marine mammals that the Inuit eat have significant glycogen stores that are able to delay postmortem degradation, particularly in cold weather.
