When you restrict carbohydrates, the body begins to process electrolytes in a different way. This is because, under conditions of low insulin, the kidneys excrete more sodium. Since there is a delicate balance between sodium and other electrolytes in the body, this increase in sodium excretion can have a knock-on effect and disrupt other electrolytes as well.
The catch, of course, is that if it sounds too good to be true, it probably is. And that’s exactly what hopeful dieters need to keep in mind when approaching the ketogenic diet (if we're calling it by its formal name). It’s not that this high-fat, moderate-protein, low-carbohydrate approach to eating can’t deliver weight loss in a delicious package, but it’s a restrictive, sometimes complicated affair that isn’t sustainable for most people.
No one is trying to diminish your success, but it does not work for everyone, and studies show it can have long term negative effects on your overall health. If you look at the Meta-analysis it shows a calorie restricted diet and Keto for 12 weeks had the same weight loss. There are also many studies that suggest looking back at people after one year those on a calorie restricted diet kept more of their weight off. The only one it does better than is just a low fat diet, which Dieticians stopped suggesting long ago. And as Health Care professionals we read the “REAL SCIENCE” not the internet articles, You Tube, Blog, book writers. One of the books written about it by Dr. Jason Fung. Have you looked him up on PUBMED? He has not written one article published in a real medical journal to be such an expert. It is not magic, it is not a cure. If you like the diet and it does not mess up your cholesterol then so be it but promoting it to others not knowing their medical history can be dangerous. What people don’t realize is that for year’s we have known that if you lose 7-10% of your own body weight your blood sugars will improve, cholesterol, and blood pressure. But you don’t have to do the fasting and put more burden on your Liver or potentially increase your risk for cardiac problems eating such high fat. If you do high fat at least do plant fats and not animal fats. But of course everyone is happy with your success but just keep a tab on your lab work.
The problem comes when people remain ketotic for extended periods. We know with confidence that long-term ketosis poses substantial risk for health complications because thousands of children have followed ketogenic diets over the years as a means of suppressing intractable grand mal seizures unresponsive to drugs, seizures that can lead to irreversible brain damage if not stopped. A ketogenic diet reduces seizures by approximately 55%. Because seizures are a chronic problem, these kids maintain ketosis for months to years.
Type 1 diabetes causes the same blood sugar control issues as type 2 diabetes, but in an entirely different way. Type 1 diabetics cannot produce enough insulin or any insulin at all, which requires them to have insulin administered exogenously. On top of that, the perfect diet will not be able to reverse this disease as the ketogenic diet can for type 2 diabetes.
Seek Nutritional Ketosis, Not Higher Ketone Levels. To gain the most benefit from this diet, you’ll want to aim for a level of ketosis between 1.5-3.0 mol/L on a blood ketone meter. You’ll be there when you are eating well-designed meals that carry you through to the next meal without hunger or other adverse symptoms (ie, nausea, insomnia, crankiness, inability to exercise). Higher ketone levels suggest you have more circulating ketones in your blood but don’t confuse this with efficient fat burning, which is the goal of this diet.
2 days from grains my stomach bloat was gone and I knew at that point everything this article and American diet was a lie. I’ve been on keto for over 16 months. Down 50lbs. In 6 months. I am ripped. Haven’t lost any muscle mass. I eat greens protein and healthy fat. I whole juice to get macros and yes I add watermelon or berries fo palatability purposes. I still eat carbs just healthy choices. I’ve become carb tolerant.. your liver will produce all glucose without ever eating 1 carb. This is biased and poor representation of keto lifestyle. When your starving and no carbs to choke keto will still thrive on either or fuel.
Financial disclosures: There were no conflicts of interest reported except for Dr Bernstein who has received royalties for books on the management of diabetes (which were used by members of the online social media group surveyed in this study). Dr. Hallberg who holds stock options and receives research support from Virta Health, and consulting fees from Atkins. Dr. Rhodes is the site principal investigator in clinical trials for pediatric type 2 diabetes that are sponsored by Merck and AstraZeneca. Dr. Westman has an ownership interest in companies using low-carbohydrate principles, and he receives royalties for books related to low-carbohydrate diets. Dr. Ludwig has received royalties from books on nutrition and obesity; and Dr. Galati is author of Eating Yourself Sick: How to stop obesity, fatty liver, and diabetes from killing you and your family (2018).
The keto diet also calls for an increased amount of fat intake. The diet suggests by cutting carb and increasing fat, the body will begin to burn the fat. However, when the body begins to burn fat, it also begins to burn the muscle tissue as well. For those participating in the diet who have a risk of heart disease or stoke, the fat increase could be put their lives at risk.
Test ketones in the late morning or afternoon. Blood and urine ketones are usually lowest right after waking up. Try testing later on, preferably a few hours after eating. Even if you’re only in ketosis for a portion of the day, you’re still getting some benefits, as discussed in this talk by Dr. Steve Phinney: Achieving and maintaining nutritional ketosis.
"Electrolyte imbalances can also be common if keto followers aren't aware of hydration needs," Turoff says. It's important to stay hydrated on keto, she says, especially in the beginning. "As you limit carbohydrates, your body produces less insulin, and glycogen stores (how carbs are stored) in the muscles and liver are depleted. For every 1 gram of glycogen that's depleted, you lose about 3 grams of water." This causes the kidneys to flush out more water, and along with it, electrolytes your body needs like magnesium, calcium, sodium, and potassium. "Imbalanced electrolytes can lead to muscle cramps, irregular heartbeat, fatigue, cognitive distortions, and lack of body temperature control," Turoff says. Some people may also be more likely to get kidney stones while on keto due to inadequate hydration, according to Turoff. (PS: These Are the Hydration Tips Every Fit Girl Needs.)
Familial Hypercholesterolemia. Familial hypercholesterolemia is a condition where one or more of the genes for the LDL receptor are defective, making it more difficult for them to clear cholesterol from the blood. If a person with familial hypercholesterolemia is then put on a high-fat diet, they will become even more vulnerable to heart disease as the increased saturated fat and cholesterol content of the diet provokes higher cholesterol levels. To counteract these genetic vulnerabilities, it is may be best to follow a low to moderate fat diet with plenty of whole foods, fiber, monounsaturated fats, polyunsaturated fats (especially omega 3s), and limited saturated fats. This, as well as a lifestyle that prioritizes physical activity, stress relief practices, and plenty of sleep, should keep their cholesterol levels under control.
I am a 7 year stroke survivor that is partially paralyzed from the stroke. I work part time and while working I walk at least 2 miles at work three to five times per week, but I can only walk 1 mph if even that speed. Which I know average speed is 3 mph when walking. I am 40 pounds overweight due to not being to do cardio workouts. I take aspirin daily as a blood thinner. I have considered getting on the keto diet. I drink sweet tea and one dr pepper per day along with coffee and water. I talked to my dr about this diet all he could tell me was he hasn’t researched it enough but knew of someone that lost weight on it. For my health I need to maintain a healthy weight and not be overweight. I have a b12 deficiency along with folic acid. I have not been taking any supplements for either.
