The gastrointestinal tract (GIT) plays a central role in the control of energy balance. Many molecules produced by the GIT exert hunger or satiety effects on the brain. Ghrelin is a peptide produced mainly by the stomach's oxyntic cells that stimulates ghrelin secretion in the hypophysis and has some neuroendocrine activities. However, its orexigenic properties are the most relevant to us and ghrelin is the only known peripheral orexigenic hormone (Date, 2012). Cholecystokinin (CCK) is a peptide produced mainly in the duodenum and jejunum that acts on the vagus nerve and directly on the hypothalamic nuclei. CCK is an anorexigenic factor and it reduces food intake, meal size and duration (Murphy et al., 2006). Three other related hormones are pancreatic polypeptide (PP), amylin, and peptide YY (PYY). PP is a peptide produced by the endocrine pancreas in relation to the caloric content of meals, and it reduces food intake both in rodents and humans. Amylin is a peptide co-secreted with insulin; its main effect on food control is a reduction of meal sizes and food intake (Murphy et al., 2006). Peptide YY (PYY) is produced in the gut and is similar to PP. PYY is stored in intestinal cells and released into the circulation as PYY3−36, a truncated form of PYY. The release of PYY3−36 is dependent on a meal's caloric and fat content (Veldhorst et al., 2008). The glucagon-like peptide 1 (GLP-1) is produced by the cleavage of pro-glucagon gene in the intestine. It acts as incretin at a pancreatic level, promoting insulin secretion and as neuro hormone on hypothalamic nuclei, inducing satiety (Valassi et al., 2008).

Sometimes we all have leftover chicken on hand that needs to be used up. Maybe you roasted a couple of chickens on the weekend to prep for the week ahead, maybe you had company over and grilled up too many chicken breasts, or maybe rotisserie chicken was on sale at your local grocery store and it was too good a bargain to pass up. Whatever the reason, we all can use a few ideas on how to use up leftover chicken.
If you remain under your optimal net carbs limit, then you should enter ketosis within 2 to 3 days. But it can take up to 7 days. The fastest way to get into ketosis is to exercise on an empty stomach, in order to accelerate the depletion of glycogen in your body. You can also do a Fat Fast for a few days (eating more fat) to speed up the rate at which you enter ketosis AND start to cut out refined carbs (like sugar) before you go for full ketosis. Another option is to do a water fast, (only drinking water) which also speeds up getting into ketosis.
If you’re following the keto diet, you will need protein, but you should limit your intake to about 20 percent of your total daily calories. (1) This is important because when you consume more protein than you need, your body converts the excess protein into carbs through a process called gluconeogenesis. This process pushes your body out of ketosis.
Moreover, recent studies show that the Inuit have evolved a number of rare genetic adaptations that make them especially well suited to eat large amounts of omega-3 fat. And earlier studies showed that the Inuit have a very high frequency—68% to 81% in certain arctic coastal populations—of an extremely rare autosomal recessive mutation of the CPT1A gene—a key regulator of mitochondrial long-chain fatty-acid oxidation—which results in a rare metabolic disorder known as carnitine palmitoyltransferase 1A (CPT1A) deficiency and promotes hypoketotic hypoglycemia—low levels of ketones and low blood sugar. The condition presents symptoms of a fatty acid and ketogenesis disorder. However, it appears highly beneficial to the Inuit as it shunts free fatty acids away from liver cells to brown fat, for thermogenesis. Thus the mutation may help the Inuit stay warm by preferentially burning fatty acids for heat in brown fat cells. In addition to promoting low ketone levels, this disorder also typically results in hepatic encephalopathy (enlarged liver) and high infant mortality. Inuit have been observed to have enlarged livers with an increased capacity for gluconeogenesis, and have greater capacity for excreting urea to remove ammonia, a toxic byproduct of protein breakdown. Ethnographic texts have documented the Inuit's customary habit of snacking frequently  and this may well be a direct consequence of their high prevalence of the CPT1A mutation as fasting, even for several hours, can be deleterious for individuals with that allele, particularly during strenuous exercise. The high frequency of the CPT1A mutation in the Inuit therefore suggests that it is an important adaptation to their low carbohydrate diet and their extreme environment.
Use fat as a lever. We’ve been taught to fear fat, but don’t! Both keto and low carb are high fat diets. Fat is our source of energy as well as satiety. The key to understand, though, is that fat is a lever on a low carb or keto diet. Carbs and protein stay constant, and fat is the one you increase or decrease (push the lever up or down) to gain or lose weight, respectively. So if your goal is weight loss, eat enough fat to be satisfied, but there’s no need to “get your fats in” once you’re satisfied.
Why is the keto diet good for you? A keto diet is one that prioritizes fats and proteins over carbohydrates. It can help reduce body weight, acne, and the risk of cancer. Find out about the mechanisms through which it achieves these benefits and the research that supports it. This MNT Knowledge Center article also discusses the risks of the diet. Read now
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.

Ketones are a special type of fat that can stimulate the pathways that enhance the growth of new neural networks in the brain. A ketogenic diet is one that is high in fats, and this diet has been a tool of researchers for years, used notably in a 2005 study on Parkinson’s patients finding an improvement in symptoms after just 28 days. The improvements were on par with those made possible via medication and brain surgery. Other research has shown the ketogenic diet to be remarkably effective in treating some forms of epilepsy, and even brain tumors.
Karen, We haven’t tried this recipe using the Ranch packets, but yes, it should work fine! To do so, we would omit the following: vinegar, chives, garlic powder, onion powder, crushed red pepper flakes, dill, salt, and black pepper, and add 2 (1 oz) packets of dry Ranch seasoning. Yes, it would probably be delicious served over white rice. If you try this recipe using the Ranch packets, please let us know how it goes!
More recently, other hypothalamic appetite control regions have been identified, including those in the arcuate nucleus (ARC), the periventricular nucleus (PVN) and the dorsomedial hypothalamic nucleus (DMH) (Valassi et al., 2008). These are sites of convergence and integration of many central and peripheral signals, not just macronutrients, that are involved in food intake and energy expenditure mechanisms, e.g., a group of neurons in the ARC stimulating food intake via neuropeptide Y (NPY) and agouti gene-related protein (AGRP). These neurons interact with those producing the anorexigenic pro-opiomelanocortin (POMC) and the cocaine/amphetamine-regulated transcript (CART) (Williams et al., 2001). Thus, a more comprehensive, unified model should include macronutrients as well as many single amino acids and other signaling molecules.
To make Crack Chicken in a slow cooker, add the chicken and cream cheese to the slow cooker. Whisk together the water, vinegar, chives, garlic powder, onion powder, crushed red pepper flakes, dill, salt, and black pepper in a small bowl and pour on top. Cook on LOW for 8 hours. Remove the chicken and shred it, and then add it back to the pot and stir in the cheddar. Cook the bacon in a skillet on the stovetop until crispy; cool the bacon and then crumble it on top.
Since this is my full-time job, donations really help me keep afloat and allow me to post as much to the website as I do. While I do really appreciate any donation you want to give, you can enter $0 in the amount given to download it for free! I’ve added in $5 as the suggested price. I think that’s a very fair price considering other websites are charging in the hundreds of dollars and I’ve seen what they are like on the inside.
Well, I am going to give this another try. I have great difficulty in eating greens , or drinking them, also I am not fond of fats, years and years of low fat diets have totally screwed my metabolism,and taste buds. I will read this page every day to keep my mind focused. Start tomorrow when I get up …… I work nights which can cause me problems as well. When I tried this diet before, I got terrible cramp, now I realise I wasn’t drinking enough water. Anyway.here goes.
This is where we have to depart! Sorry to say but you’re on your own. You should have plenty of leftovers that are frozen, ready, and waiting! I know a lot of you out there have trouble with timing and are busy people – so making sure that some nights you make extras to freeze is important. All those leftovers you have in the freezer? Use them up! Create your own meal plan, at first using this as a guide, and then completely doing it yourself. Once you get the hang of it, it’ll be a sinch – I promise you 🙂

As a diabetic and lactose intolerant, this is the only way I can eat ice cream. I add unsweetened cocoa and extra aspartame to make a wonderful chocolate ice cream, then I add chopped up bananas or 1/2 tsp of peppermint extract – yum! Or instead of chocolate, I add lemon and peppermint extracts, together. Great! For the serious chocoholics, melt some dark chocolate in the microwave and add that to the unsweetened cocoa – incredible!
This is in part because patients need to be in deep ketosis to see an impact on epilepsy, likely deeper than the average dieter, but without a nutritionist guiding you it’s still hard to get down into ketosis. It’s not exactly clear why ketosis seems to improve epilepsy, but it seems to have something to do with the brain’s use of ketone bodies in place of glucose, which only happens when you’re nearly in starvation mode. (It's important to note here that "starvation mode" is not in reference to how hungry you feel.)
This is the only way my kids will eat Brussels sprouts! It’s actually great for me because this dish is fast, easy and healthy, and it makes a lovely side. Quick-cooking Brussels sprout halves are available in the prepackaged salad aisle at the grocery store. They’re a timesaver if you can find them, but you can always just buy whole ones and slice them in half. —Teri Rasey, Cadillac, Michigan
My husband is trying to eat more Keto meals and this recipe is made up of his FAVORITE things! I sent him the link to it and he was inspired! Last night, he made himself a big hearty batch of this recipe and thoroughly loved it. He even shared photos of his meal on Facebook and our friends were in awe of his creation and the recipe you provided. I don’t enjoy mushrooms, so I’m reviewing this on my husband’s behalf. It was EXCELLENT!
Ally, We haven’t tried this recipe with another cooking method, but it should actually be pretty easy! The objective is to cook the chicken (any way you like, poached, baked, grilled, or even rotisserie) until it can be shredded, and then mix the shredded chicken with the creamy sauce. To cook the creamy sauce on the stovetop, we recommend crisping the bacon in a saucepan and then removing it and adding the water and spices. Once the water is simmering, add the cream cheese a bit at a time (slightly softened would probably work best), whisking until it’s incorporated. Cooked this way, you may need to add a splash more liquid (water or broth, if you prefer) to the sauce, because some of the liquid will evaporate off as the cream cheese melts down. Finally, stir in the cooked shredded chicken and shredded cheddar, and serve! If you try it this way, please let us know how it goes!
Note that urine measurements may not reflect blood concentrations. Urine concentrations are lower with greater hydration, and after adaptation to a ketogenic diet the amount lost in the urine may drop while the metabolism remains ketotic. Most urine strips only measure acetoacetate, while when ketosis is more severe the predominant ketone body is β-hydroxybutyrate. Unlike glucose, ketones are excreted into urine at any blood level. Ketoacidosis is a metabolic derangement that cannot occur in a healthy individual who can produce insulin, and should not be confused with physiologic ketosis.
To encourage ketone production, the amount of insulin in your bloodstream must be low. The lower your insulin, the higher your ketone production. And when you have a well-controlled, sufficiently large amount of ketones in your blood, it’s basically proof that your insulin is very low – and therefore, that you’re enjoying the maximum effect of your low-carbohydrate diet. That’s what’s called optimal ketosis.
Most carbs you consume are broken down into sugar that enters the bloodstream. When you rein in carbohydrates on the keto diet, you have lower levels of blood glucose (high blood glucose can lead to diabetes). A study in the journal Nutrition reveals that a ketogenic diet improves blood glucose levels in type 2 diabetics more significantly than a low-calorie diet and can also decrease the dosage of your diabetes meds.
No and yes. The liver can make ketones out of alcohol, so technically, when you drink you'll continue to produce ketones and so will remain in ketosis. The problem is ... alcohol converts more easily to ketones than fatty acids, so your liver will use the alcohol first, in preference to fat. Thus, when you drink, basically your FAT burning is put on hold until all the alcohol is out of your system.
Thanks for the recipe Katie. It is definitely a task sifting through all the info on keto diet. Lots of stuff on how to start the diet. I’m thinking results come from sticking to it and “finishing” the diet, aka changing lifestyle. I’ve found with other things that having a mentor is crucial. It creates accountability and reminds you that you really are on the right track!
Jump up ^ Lawrie 2014, pp. 92-. "A much delayed onset of rigor mortis has been observed in the muscle of the whale (Marsh, 1952b). The ATP level and the pH may remain at their high in vivo values for as much as 24h at 37ºC. No adequate explanation of this phenomenon has yet been given; but the low basal metabolic rate of whale muscle (Benedict, 1958), in combination with the high content of oxymyoglobin in vivo (cf 4.3.1), may permit aerobic metabolism to continue slowly for some time after the death of the animal, whereby ATP levels can be maintained sufficiently to delay the union of actin and myosin in rigor mortis."
The hypothalamus is the brain's main center responsible for hunger/satiety (H/S) control. In the theory that Mayer proposed more than 60 years ago, he assigned a central role to glucose levels in the H/S control: the so-called “glucostatic theory” (Mayer, 1955). Mayer suggested that depletion of carbohydrate availability leads to hunger, and the hypothalamic centers with receptors sensitive to glucose levels might be involved in the short-term regulation of energy intake (Mayer, 1955). The “feeding center” in the lateral hypothalamic area (LHA), according to the glucostatic theory, reacts to the between-meal fall of blood glucose and stimulates food intake. The LHA contains glucose-inhibited neurons that are stimulated by hypoglycemia, a process crucial to mediating the hyperphagia normally induced by hypoglycemia. The subsequent post-prandial hyperglycemia activates the “satiety center” in the ventromedial hypothalamus (VMH), which contains glucose-excited neurons and inhibits both “feeding center” and food intake.
If you want to slam a protein shake post-workout, that's probably fine as long as you've got room for it in your macros. But shoot for one that is very low—like, zero—in carbohydrates. Pure isolates, such as Signature 100% Whey Isolate, are extremely low in carbohydrate. If you struggle to fit fat in during the day, toss a tablespoon of olive oil in with your shake. You won't taste it, and it gives a quick 13-14 grams of fat.
The most science-backed performance-boosting supplements, such as creatine monohydrate, beta-alanine, and caffeine, are all A-OK on the ketogenic diet. So, if you take a pre-workout, you should be able to continue without issue. I would also recommend gulping down some bouillon before your session to ensure your sodium and magnesium levels are on point.
Ketosis is an option for many people with type 2 diabetes because they still produce insulin, which helps their body maintain a safe level of ketones in the blood. If you’re considering trying ketosis or the ketogenic diet with type 2 diabetes, be sure to consult your healthcare provider first to ensure it’s safe for you. This eating approach may interfere with some types of diabetes medication or be inappropriate for you if you have certain diabetes complications, such as kidney damage.
Normal body cells metabolize food nutrients and oxygen during cellular “respiration”, a set of metabolic pathways in which ATP (adenosine triphosphate), our main cellular energy source is created. Most of this energy production happens in the mitochondria, tiny cell parts which act as powerhouses or fueling stations. There are two primary types of food-based fuel that our cells can use to produce energy:
What is the link between ketones and diabetes? Ketone is a chemical produced by the body when fats are broken down for energy. Ketone testing is important for people with diabetes, because high levels can lead to diabetic ketoacidosis (DKA), when acid levels become too high in the blood and the person loses consciousness. Find out when and why to do ketone testing. Read now
There are many misconceptions about ketosis. The most common is mixing it up with ketoacidosis – a rare and dangerous medical condition that mostly happen to people with type 1 diabetes if they don’t take insulin. Even some health care professionals tend to mix up these two situations somewhat, perhaps due to the similar names and a lack of knowledge about the distinct differences.
Alcoholic ketoacidosis (AKA) presents infrequently, but can occur with acute alcohol intoxication, most often following a binge in alcoholics with acute or chronic liver or pancreatic disorders. Alcoholic ketoacidosis occurs more frequently following methanol or ethylene glycol intoxication than following intoxication with uncontaminated ethanol.
The fatty acids then flow into the bloodstream and are taken up by body tissues. Once in the cells, the fatty acids are transported into the mitochondria of the cell to be metabolized carbon by carbon in a process called beta-oxidation. As glucose levels fall and fatty acid levels in the blood rise, the liver cells ramp up beta-oxidation which increases the amounts of a molecule called Acetyl-CoA. As the level of Acetyl-CoA rises, it is shunted to a process called ketogenesis. Ketogenesis generates a ketone body called acetoacetate first, and this ketone is then converted into the two other types of ketones: beta-hydroxybutyrate, and acetone. Meanwhile, the glycerol part of the fat molecule gets converted into glucose in a process called gluconeogenesis, which means "make new sugar".
The remaining calories in the keto diet come from protein — about 1 gram (g) per kilogram of body weight, so a 140-pound woman would need about 64 g of protein total. As for carbs: “Every body is different, but most people maintain ketosis with between 20 and 50 g of net carbs per day,” says Mattinson. Total carbohydrates minus fiber equals net carbs, she explains.
