What Is The Ketogenic Diet And Is It Healthy? Should It Be Used As A Normal Way Of Eating Instead Of A Weight Loss Diet?

Ketogenic diet, or in short Keto, is a form of diet that focuses on intentionally shifting the body’s metabolism from glucose (carbs) to Ketones (fats), in essence, to put it on Ketosis. In Ketosis, the cells in the body use Ketones (formed by breaking down fat cells) instead of glucose (formed from carbs or sugars) to derive energy for bodily functions and metabolism. In this diet, the dieter is expected to obtain their daily calorific requirements i.e., energy for metabolism, primarily from fats (65-75%) and proteins (15-25%) instead of carbohydrates (5-10%) depending on requirement. Although Ketogenic diet has existed for over a century, it has only found prominence in recent years owing to its considerable impact on weight loss and other health benefits. The unconventional mechanism of Ketogenic diet creates a considerable amount of doubt as well as curiosity among new dieters. People, who have gone through the diet, swear by it. However, at the same time the unorthodox nature of the diet coupled with the mechanism’s similarity with starvation, has led many researchers to question its efficacy. In fact, many believe that Ketogenic diet is actually harmful to the human body Continue reading >>

    Ok not really . . . but I was told today by a VERY passionate Human Nutrition student. I've also read a few other studies that warn against long term dangers of eating Keto (longterm). I'd like to try to find some scientific evidence to back up that it is good (and to also reassure myself) . . . thoughts? Research? Articles?
    Here was what she sent me:
    I am in my last year as a BSc Human Nutrition and I have several things to say about the ketogenic diet, which I won't say in totality here because it will probably be a book.
    I'll summarize: Ketogenic diets are NOT okay for your body. Metabolically, ketogenic diets are a last resort once your body is expended of all its energy and begins to burn fat and protein instead of carbs as energy. As such, breakdown products are not easily metabolized by the body in the way that carbohydrate, your body's #1 fuel source, is. It's extremely unhealthy, creates toxic byproducts ("free radicals" if that means anything to you; it's hard on your liver) and actually ends up lowering more of your muscle mass than your fat mass in your body. You will lower your muscle mass as your body burns ketones (breakdown products of both fat and muscle tissue; primarily muscle as it is easily broken down wrt stored fat), thereby decreasing your resting metabolic rate and inducing false starvation, encouraging your body to burn MORE muscle (it's broken down more easily than fat) and starting a really bad circle. also your brain runs EXCLUSIVELY on glucose (a carb; a sugar) and inducing ketosis in your body reduces this fuel heavily. Carbohydrates are essential in every diet to fuel the brain: at least 120g per day for the average person. Pls don't deprive yourself of carbs, your brain needs them heart emoticon (also the rest of your body needs them, as they serve essential metabolic functions in terms of cellular regeneration, immune function and general maintenance pls take care of your body)

    Metabolically, ketogenic diets are a last resort once your body is expended of all its energy
    That would be starvation.
    and begins to burn fat and protein instead of carbs as energy.
    Burning fat is kinda the point. Protein usage is actually less than when you suddenly run out of glycogen on a high carb diet. This is why keto is "muscle sparing" during diets. It's not that keto is magical, it's that the lack of the ability to burn fat efficiently means the body will try to derive glucose from protein when short on energy.
    As such, breakdown products are not easily metabolized by the body in the way that carbohydrate, your body's #1 fuel source,
    This is why we need an adaptation period where the body sets up the necessary metabolic machinery to metabolize fat and ketones efficiently. Besides, ethanol is the most readily metabolized, does it mean it is the #1 fuel source?
    It's extremely unhealthy,
    Hundreds of thousands, if not millions of people are on keto without major issues. The same can not be said for carbohydrate-rich diets.
    creates toxic byproducts ("free radicals" if that means anything to you;
    It actually produces less waste for the same amount of energy. It might produce more hydrogen peroxide according to a rat study, but endogenous antioxidant defenses are upregulated to deal with it. It helps against grey hair, which is caused by the loss of ability to deal with hydrogen peroxide. Hmmm now that I think about it, it might even work against vitiligo.
    it's hard on your liver)
    Glycogen storage and retrieval, de novo lipogenesis, carbohydrate-induced lipotoxicity and hyperglycemia, fatty liver are arguably much worse for your liver than ketogenesis.
    and actually ends up lowering more of your muscle mass than your fat mass in your body
    Not if you give it enough protein. I am actually able to gain strength and muscle on keto and StrongLifts as opposed to 2-3 years of high carb diet and overtraining.
    You will lower your muscle mass as your body burns ketones (breakdown products of both fat and muscle tissue; primarily muscle as it is easily broken down wrt stored fat),
    I do not think it is possible to convert amino acids into ketones. At least not without converting them to fat first, which I doubt happens to muscle protein.
    thereby decreasing your resting metabolic rate and inducing false starvation,
    Metabolic rate is downregulated only after prolonged fasting, and is not modified during keto. In fact, energy levels can increase. Keto resembles starvation much less than commonly thought. A full-fledged starvation response between hunts would not make any sense from an evolutionary point of view.
    encouraging your body to burn MORE muscle (it's broken down more easily than fat) and starting a really bad circle.
    Again, keto encourages fat usage over muscle breakdown.
    also your brain runs EXCLUSIVELY on glucose (a carb; a sugar)
    The brain has only a very small requirement of glucose that can not be substituted by ketones, somewhere around 20-30 grams. Moreover, this amount can be fully synthesized from protein, of which dietary protein is preferred by the body.
    and inducing ketosis in your body reduces this fuel heavily.
    Keto does not reduce the availability of glucose, it reduces the usage. Your serum glucose stays roughly the same, assuming it was normal in the first place. Tissues that rely on glucose continue to function in the same way. Diabetics and prediabetics often see the normalization of serum glucose, which is a good thing obviously.
    Carbohydrates are essential in every diet to fuel the brain:
    Dietary carbohydrates are non-essential. This is demonstrated by the continued existence of /r/zerocarb people.
    at least 120g per day for the average person.
    I actually consider 120 grams of carbohydrates the cutoff limit for low carb diets. Serum glucose and liver glycogen can only hold the equivalent of 120 grams of carbohydrates. If you eat less than that, you are guaranteed not to fill your liver glycogen, and your body has to look for other sources of energy. The average person should eat less than 120 grams of carbohydrates to maintain metabolic and general health.
    Pls don't deprive yourself of carbs, your brain needs them heart emoticon
    No it doesn't, middle finger emoticon.
    (also the rest of your body needs them, as they serve essential metabolic functions in terms of cellular regeneration, immune function and general maintenance pls take care of your body)
    Again, processes that require glucose continue to function normally.
    I am in my last year as a BSc Human Nutrition and I have several things to say about the ketogenic diet, which I won't say in totality here because it will probably be a book.
    Do a few years of research first before even considering a book, you are woefully inexperienced on the subject. I have a comp sci degree and still know more on the subject for fucks sake.

    I felt gold was necessary for this line alone.
