Dr. Guido Kroemer is a professor at the University of Paris Descartes and an expert in immunology, cancer biology, aging, and autophagy. He is one of the most highly cited authors in the field of cell biology and was the most highly cited cell biologist for the period between 2007 and 2013. Especially notable among his contributions: he was the first to discover that the permeabilization of mitochondrial membranes is a concrete step towards apoptotic cell death. This episode is decidedly focused on autophagy, an important cellular program that is inducible by dietary fasting and has broad implications for aging and cancer. Autophagy discussion includes: 00:04:44 - How the 3 main signals that activate autophagy all involve nutrient sensing. 00:16:30 - The role of different types of fasting and nutrient deprivation in autophagy. 00:24:35 - How different types of exercise can induce autophagy. 00:32:04 - How a specific type of autophagy called mitophagy keeps mitochondria healthy. 00:33:07 - How autophagy has been shown to slow cellular aging. 00:35:13 - How autophagy prevents neurodegenerative diseases by clearing away protein aggregates. 00:44:04 - The role of autophagy in cancer as a possible double-edged sword. 00:50:27 - How certain compounds known as caloric restriction mimetics (or fasting mimetics) including resveratrol, spermidine, hydroxycitrate can induce autophagy by tricking the cell through the modulation of one or more of the 3 main autophagy signaling pathways.

Psychological And Physical Differences Between Fasting And Caloric Restriction

Psychological and Physical Differences Between Fasting and Caloric Restriction You are listening to the Shortcut to Slim Podcast. Show details Hosted by Lindsay S Nixon Season 2: Episode 1 If youve ever felt like diet is basically DIE with a T on the end Or have been miserably hungry while trying to lose weight Or started having obsessive food thoughts This episode will explain WHY and what you can do about it. Plus Ill dig into the physical and psychological differences between fasting and caloric restriction which also means youre going to learn about gherlin and ketosis! After last season I swore up and down I wouldnt talk anymore on fasting because Id exhausted that topic and wanted to focus on the brain. I went face down into stacks of research on neuroscience and uncovered some seriously cool studies on food psychology and became totally obsessed CBT (cognitive behavior therapy) is my favorite but then right at the end my work whipped right back around to fasting so here we are again. But you know, thats cool. I like a bridge. I like that the research from Season 1 fits connects with season 2. Last season I cracked open the myth about starvation mode. Theres not a scrap of e Continue reading >>

    can you go into starvation mode while on keto?

    Okay.. so ya'll can correct me if I'm wrong on this one..
    But when your body goes into starvation mode it's because you aren't fueling it enough.. not giving it enough energy..
    Well if your body is using fat for energy.. when you run out of fat that you're eating.. wouldn't your body just use the fat you already have instead of going to starvation mode?
    Or am I totally off..?

  2. Atavis

    Yes. Yes, you definately can go into starvation mode on keto.

Ketosis

Not to be confused with Ketoacidosis. Ketosis is a metabolic state in which some of the body's energy supply comes from ketone bodies in the blood, in contrast to a state of glycolysis in which blood glucose provides energy. Ketosis is a result of metabolizing fat to provide energy. Ketosis is a nutritional process characterised by serum concentrations of ketone bodies over 0.5 mM, with low and stable levels of insulin and blood glucose.[1][2] It is almost always generalized with hyperketonemia, that is, an elevated level of ketone bodies in the blood throughout the body. Ketone bodies are formed by ketogenesis when liver glycogen stores are depleted (or from metabolising medium-chain triglycerides[3]). The main ketone bodies used for energy are acetoacetate and β-hydroxybutyrate,[4] and the levels of ketone bodies are regulated mainly by insulin and glucagon.[5] Most cells in the body can use both glucose and ketone bodies for fuel, and during ketosis, free fatty acids and glucose synthesis (gluconeogenesis) fuel the remainder. Longer-term ketosis may result from fasting or staying on a low-carbohydrate diet (ketogenic diet), and deliberately induced ketosis serves as a medical i Continue reading >>

You may read that it is a dangerous state for the body, and it does sound abnormal to be in ketosis. But ketosis merely means that our bodies are using fat for energy. Ketones (also called ketone bodies) are molecules generated during fat metabolism, whether from the fat in the almonds you just ate or fat you were carrying around your middle. When our bodies are breaking down fat for energy, most of it gets converted to energy, but ketones are also produced as part of the process. When people eat less carbohydrates, their bodies turn to fat for energy, so it makes sense that more ketones are generated. Some of those ketones (acetoacetate and -hydroxybutyrate) are used for energy; the heart muscle and kidneys, for example, prefer ketones to glucose. Most cells, including the brain cells, are able to use ketones for at least part of their energy. Learn more about ketosis: https://sherwoodwellness.tv/low-carb-...

The Truth About Ketosis & Low-carb Diets, Backed By Science

A lot of people are confused by the term “ketosis.” You may read that it is a “dangerous state” for the body, and it does sound abnormal to be “in ketosis.” But ketosis merely means that our bodies are using fat for energy. Ketones (also called ketone bodies) are molecules generated during fat metabolism, whether from the fat in the almonds you just ate or fat you were carrying around your middle. When our bodies are breaking down fat for energy, most of it gets converted to energy, but ketones are also produced as part of the process. When people eat less carbohydrates, their bodies turn to fat for energy, so it makes sense that more ketones are generated. Some of those ketones (acetoacetate and ß-hydroxybutyrate) are used for energy; the heart muscle and kidneys, for example, prefer ketones to glucose. Most cells, including the brain cells, are able to use ketones for at least part of their energy. Is ketosis a bad thing? There is an assumption that if a body is burning a lot of fat for energy, it must not be getting “enough” glucose. However, there is no indication, from studying people on reduced carbohydrate diets, that this is the case (though there is usuall Continue reading >>

    Unfortunately, biochemistry is not the kind of topic that can be easily researched online without formal training. There are a number of points you make that are incorrect. I keto myself, so don't think I am trying to attack your general position here.
    Starvation and the keto diet are actually nearly identical from a biochemical perspective. The key pathway is fat mobilization, where fatty acid chains are broken down two carbons at a time to produce energy. When this process starts to happen faster than your body can manage it, some of the chemical constituents of the process actually break down to become the ketones that can be detected in the urine and breath. In other words, ketones are a side effect, rather than a major player.
    The idea that a calorie deficit, ie starvation, is somehow bad, is incorrect. Anybody who is using diet and exercise to become more lean is doing the same thing. There is no magic method to lose weight without some form of starvation. The reason why the keto diet does not cause significant lean tissue loss is that the starvation involved is not sufficiently severe.
    An important point that you bring up is the idea that the keto diet stabilizes insulin levels. This is basically correct. Insulin signals cells to take up glucose from the blood, and also tells the liver to begin glycogenesis - the process of packing glucose into glycogen. High blood sugar triggers this. These effects are basically reversed by adrenaline, which tells the liver to start breaking glycogen down to make glucose.
    Part of the difficulty with this is that with a normal diet, blood sugar spikes after meals. This leads to cyclic variance in levels of glucose, insulin and adrenaline. As the cycle progresses toward the adrenaline end, you start to get cravings for foods that will once again spike your blood glucose.
    However, when you are relying on fat mobilization to make glucose, these spikes are greatly reduced. Fat mobilization is not efficient, and is not able to provide sudden bursts of glucose. It is more constant. This makes athletic activity much more difficult aswell.
    But this is the real reason why the keto diet works - it mitigates the cycle of spiking and lowering blood sugar, providing a more level and constant supply. This reduces the propensity for craving food.
    In essence, the keto diet is not unique in terms of the basic biochemistry of metabolism. It simply makes 'starvation' more tolerable, and easier to manage. For many of us, that is exactly what we need.
    Edit - swapped 'gluconeogenesis' with 'glycogenesis'.

These effects are basically reversed by adrenaline, which tells the liver to start breaking glycogen down to make glucose.
    Insulin inhibits gluconeogenesis (creation of new glucose), you probably meant glycogenesis (conversion of glucose to glycogen)?

  3. datums

    You are right on that one. The word I was looking for was glycogenesis. It can be a little tricky to remember that between glycolysis, glucogenesis, and gluconeogenesis, one means glycogen synthesis, and the other two mean glycogen breakdown.

    Good questions! First, our bodies need fuel and the first fuel they use is sugars (or carbs), so if you’re eating “anything” as you suggest the only way you would start to burn fat would be if your caloric deficit were enough that you needed to burn more fuel than the sugars and carbs you were putting in your body. This is physically possible on low calorie diets (which is why so many people try them), but usually in order to keep your calo ...

    "Ketosis" is a word you'll probably see when you're looking for information on diabetes or weight loss. Is it a good thing or a bad thing? That depends. Ketosis is a normal metabolic process, something your body does to keep working. When it doesn't have enough carbohydrates from food for your cells to burn for energy, it burns fat instead. As part of this process, it makes ketones. If you're healthy and eating a balanced diet, your body controls ...
