So our brains do require some glucose, and this is the main reason that registered dietitians (RDs) will tell you that carbohydrates are essential nutrients (meaning we have to eat them or we will die). But a biochemical fact check shows that this is not true. RDs neglect the research which shows that the brain can use ketones for over half of its fuel requirements once carbohydrate intake is lowered and ketone levels ramp up to full production. When ketones are available as a secondary fuel source, the brain requirement for glucose is lower, and the process of gluconeogenesis can make all the glucose the brain needs (about 50 grams/day). So although glucose is essential for the brain, eating carbohydrates to make glucose for the brain is NOT required. If you are have blood ketone levels above 1-3 mmol, the brain can use the ketones as an alternative fuel source.

Devine says not to jump right into keto cycling. “I would definitely not try keto cycling until you’re about two to three months into your keto diet,” she says. “That's because you need to make sure your body is fat adapted so that it can get back into ketosis easily.” In her practice, Devine has noticed that if the body is used to being in ketosis, it’ll snap back more quickly after eating a carb-heavy meal than if a person is new to keto, though there’s no firm research to support that this is always the case.

A: The amount of weight you lose is entirely dependent on you. Obviously adding exercise to your regimen will speed up your weight loss. Cutting out things that are common “stall” causes is also a good thing. Artificial sweeteners, dairy, wheat products and by-products (wheat gluten, wheat flours, and anything with an identifiable wheat product in it).
My doctor recommended a keto diet for me despite me having an eating disorder and being vegan. It has been so difficult to try to follow that it has made everything worse. My eating disorder is worse, my depression is worse, my anxiety around food is through the roof. I am so glad I found your article because it’s been so hard finding anything anti-keto! I needed to read that it was driving other people crazy too and was dangerous, so thank you. I am slowly reintegrating carbs but i do believe a lot of damage has been done in regards to my psychological health that it will take a long time to recover from this “diet”.
Your dietary needs change dramatically with keto. Sodium becomes a critical nutrient, as do magnesium and potassium. “At least in the initial stages of being on the keto diet, you will urinate more. One of the key electrolytes lost through urination is magnesium,” says Carolyn Dean, MD, ND, a health and nutrition expert and author of The Magnesium Miracle. “Magnesium is an energy mineral, which will help you burn fat and lose weight.”
"I always make an assessment of whether or not the cheat is worth it and 99 percent of the time, it’s not. If I do have a cheat meal, I don't worry about what the scale says afterward. I want to be happy with the decision before I make it, during it, and after I make it. A lot of it is living with your decisions and not beating yourself up over it."

Some people believe elite athletes benefit from keto cycling because their bodies use extra carbohydrates as energy to power through difficult workouts and races. After all, research shows that following the strict keto diet impairs exercise performance. A 2017 study published in The Journal of Physiology found keto hurts athletic performance more than a high-carbohydrate diet or one that includes periods of high carbs and low carbs (which is similar to keto cycling).
I don’t agree with this article completely. I’ve been Keto for a year and half and have kept off the 45 lbs I’ve lost. I’ve gained more muscle mass by lifting and take mineral supplements which I needed before as well. I’ve not purchased and if the Keto “stuff” everyone seems to be selling these days. I still love this way of eating since my intestinal issues after gone and I’m feeling great. It may seem like a fad and with that reach person needs to research very careful to what is healthy and what is not.
Although the hunger-reducing effect of KD is well-documented, its main mechanisms of action are still elusive. The global picture is complicated by the contradictory role of ketosis on anorexigenic and orexigenic signals (summarized in Figure ​Figure4).4). Ketones (mainly BHB) can act both orexigenically or anorexigenically. In the orexigenic mechanism, it increases the circulating level of adiponectin, increasing brain GABA and AMPK phosphorylation and decreasing brain ROS production. The anorexigenic mechanism triggers a main normal glucose meal response, increasing circulating post-meal FFA (thus reducing cerebral NPY), maintaining CCK meal response and decreasing circulating ghrelin. It can be postulated that the net balance of the contrasting stimuli results in a general reduction of perceived hunger and food intake. More studies are needed to explore the mechanism of potential beneficial effects of KD on food control.
Fortunately, Drs. Kevin Hall and Juen Guo had the same burning question. In 2017, they analyzed the data and published a meta-analysis of controlled feeding studies that compared diets of equal calorie and protein content with variations in carbohydrate and fat content. [24] By filtering out the diet data in this way, the researchers could finally find out whether restricting carbs or limiting calories is more important when it comes to weight loss.
Might not be nutritional. Could be a training issue. Could be fascial. Could be neurotransmitter. If you're taking 1 serving of UCAN perhaps you need two. Not sure of ht, body wt, etc. I'd be happy to help you via a personal one-on-one consult. Just go to https://bengreenfieldfitness.com/coaching. and then choose a 20 or 60 minute consult, whichever you'd prefer. I can schedule ASAP after you get that.
Now, I’m in low carb recovery, I need to re-lose some of what I’ve gained in the carb rebound, and to do it I’m just counting calories. I’m only 5’4, so I have a goal of 1620 per day, with the understanding that I am not going to hit that goal every day, because sometimes I will eat out or eat a donut that’s brought in at the office. I finally got tired of saying “I can’t have that” or lying and saying I didn’t even want it. Now, if I want to eat something, I eat it. I can adjust my other decisions for the day if necessary to accommodate a treat, or not, it just depends on how I feel. Some days I feel motivated to lose weight, and some days I feel motivated to eat ice cream, and the one desire does not have to destroy the other. I finally feel like I can enjoy the goodness of all of the food groups again, and I am steadily losing an average of 1 lb per week – no longer miserable.
Weight loss caused by low-carb diets isn’t just because of a loss of “water weight”. In research studies that measured change in body fat, subjects eating low-carb diets had a greater loss in body fat than those eating low-fat diets. Additionally, keto diets lead to a greater reduction in waist circumference, a critical indicator of harmful stomach fat.
Easy: use about half of the recommended serving of Glycofuse, and instead add one scoop of Catalyte electrolytes, one scoop of Kion Aminos, and one serving of ketones and/or MCT’s in the form of Brain Octane, KetoCaNa or KETO//OS (pick your poison, it’s up to you). While any of these forms of ketones and/or MCT’s works for daily focus and short workouts, I found that for long workouts they aren’t very gut friendly unless you really spread out the dosage (e.g. one serving every three hours), so you’d only really use that stuff in something like, say, an Ironman triathlon or multi-day adventure race.
Under normal functioning, leptin enters the bloodstream via your circulatory system and then binds to protein in the blood. When it reaches your brain capillaries, it travels across the blood-brain barrier (BBB), binding to leptin receptors on the hypothalamus portion of your brain. Leptin then clues your brain into the fact that you’re full.[4][5]
What would your advice be to a high raw vegan who wants to try an HRV keto diet? The supps you recommended above look vegan, but aren’t the results based on those of omnis? Would they work the same way on vegans? Also I heard you mention in the recent Keto Summit that SE Asians need a little more carb and I happen to be one. I’m a petite 39-YO female and I’ve been raw for the past 11 years. I have been practicing intermittent fasting in the last 7 years and try to eat only twice a day. Up to how many grams of carbs can I consume to get into ketosis?

The DNA test does not necessarily take into account your goals (e.g. breathholding, Ironman, cognition, etc.) and if your goals would benefit from ketosis, then you may want to choose it as a dietary strategy even though it could indeed be true that for FAT LOSS a higher carb intake may suit you. So it all depends on your goals. Or you could just us the supplements like ketones AND eat more carbs and get "best of both worlds".
While it is believed that carbohydrate intake after exercise is the most effective way of replacing depleted glycogen stores,[72][73] studies have shown that, after a period of 2–4 weeks of adaptation, physical endurance (as opposed to physical intensity) is unaffected by ketosis, as long as the diet contains high amounts of fat, relative to carbohydrates.[74] Some clinicians refer to this period of keto-adaptation as the "Schwatka imperative" after Frederick Schwatka, the explorer who first identified the transition period from glucose-adaptation to keto-adaptation.[75]
L-glutamine is an amino acid with many functions in your body including acting as a powerful antioxidant[*][*]. Research shows that L-glutamine can help stabilize blood glucose levels[*] and has been recommended to help reduce sugar cravings. Supplementing with L-glutamine (about ½-1 teaspoon powdered form or 500 mg dose) may help in reducing carb/sugar cravings and aid in your ketogenic weight-loss journey.
