In the second of these posts I discuss the Delta G implications of the body using ketones (specifically, beta-hydroxybutyrate, or BHB, and acetoacetate, or AcAc) for ATP generation, instead of glucose and free fatty acid (FFA). At the time I wrote that post I was particularly (read: personally) interested in the Delta G arbitrage. Stated simply, per unit of carbon, utilization of BHB offers more ATP for the same amount of oxygen consumption (as corollary, generation of the same amount of ATP requires less oxygen consumption, when compared to glucose or FFA).
Long-Term Effects of a Ketogenic Diet in Obese Patients – The present study shows the beneficial effects of a long-term ketogenic diet. It significantly reduced the body weight and body mass index of the patients. Furthermore, it decreased the level of triglycerides, LDL cholesterol and blood glucose, and increased the level of HDL cholesterol. Administering a ketogenic diet for a relatively longer period of time did not produce any significant side effects in the patients. Therefore, the present study confirms that it is safe to use a ketogenic diet for a longer period of time than previously demonstrated.(http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2716748/)
Blood d-βHB, pH, bicarbonate (HCO3-) and electrolytes measured in arterialized blood samples from resting subjects (n = 7) following a ketone ester or salt drink containing 3.2 mmol.kg−1 of βHB. Shaded areas represent the normal range. Values are means ± SEM. (A) Venous blood d-βHB. (B) Arterialized blood pH. (C) Blood bicarbonate. (D) Blood potassium. (E) Blood sodium. (F) Blood chloride. †p < 0.05 difference between KE and KS, *p < 0.05 difference from baseline value.
The same question posed in a different way can be, what’s better, getting protein from powder or from a grass-fed steak or wild salmon? Omega-3 from supplements or from a variety of healthy wild fish? Just like with health supplements where you consume an isolated nutrient instead of the whole food where it comes from, if it’s possible to get what you need from whole food or nutrition, then that’s probably the best choice.
This is probably one of the most understood notions of a true ketogenic diet (and the difference between a keto diet and a low carb diet). An optimal ketogenic diet will be low in carbohydrates AND protein. Many people who have experimented with low carb dieting simple reduce carbs and increase protein. A big reason behind this is due to the misconception that ‘’excess fat is bad – which is untrue, more on this HERE). However, excess protein can be converted to glucose (blood sugar) through a process called gluconeogenesis.
You are probably wondering how there could possibly be a benefit to eating less frequently that goes beyond what you are already getting with a ketogenic diet. Restricting carbs and eating enough fat and protein does come with a plethora of health benefits, but when you add intermittent fasting to your lifestyle you can increase energy and reverse aging by harnessing the power of a nobel prize winning process.
Pruvit v Perfect Keto: One of the more popular brands for BHB salts is Pruvit (Keto OS). Pruvit is a good brand, but they do use some additives. Also, Pruvit is an MLM company that has tons of people pushing their products as the best weight loss product in the world. And you have to use one of their representatives’ referral codes to buy it. Learn more about the two in this Pruvit vs Perfect Keto comparison article.
A growing number of people are giving it a try, thanks to exogenous ketone supplements that claim to launch your body into a state of ketosis within two and a half days—even if you’ve been living on pasta and cookies instead of following a low-carb diet. How can that be, though? And can that kind of rapid transformation actually be safe? Here’s what you should know.
The liver is always producing ketones to some small degree and they are always present in the bloodstream. Under normal dietary conditions, ketone concentrations are simply too low to be of any significant benefit. A ketogenic diet and exogenous ketone supplements will increase the amount of ketone in your body. The idea that ketones are “toxic” is ridiculous. Ketones are a normal physiological substance that play many important roles in the human body.
Humans in the hunter-gatherer era survived thanks to metabolic flexibility — the body’s ability to use different fuels for energy depending on the nutrients available. This adaptation was vital during a time when the source, quantity, and frequency of food was uncertain[*]. Most of the time, people were fasting, so their bodies ran on ketones, not glucose.
