The Concept Of Metabolic Flexibility With Robb Wolf

20 Minute Fitness


Let's dive a bit deeper into metabolic health in general. I would say the us stephanie. Facing metabolic health. Dem's it's become so so tough that you know. Diabetes is on the rise diabetes type two and obesity is on the rise and aloft. It can be let back to metabolic flexibility or the lack of it. Maybe can talk about more about the concept actually pollick expolit the actually means and why it is important. Yeah being metabolic flexible in in kind of a textbook definition really speaks to the ability to use a variety of different fuel sources that mainly really carbohydrate and fat though although by extension ketone very seamlessly with with little drama little difficulty really not a big change in in performance or perception. My wife is an example of somebody who's very metabolic flexible. She can go kito goes in. She goes out no headache. Lethargy no problems She can eat a fair amount of carbs and doesn't suffer. You know a really crazy blood. Sugar excursion she doesn't get like blood. Sugar crashes unless she really you know if she a ghost for the extra large mexican meal of beans and rice and tortillas and you know and right and then she can feel kinda rough from that like she can overdo it but she needs to really try to do that and in researching some material for my second book wired to eat. We did some side by side. Comparisons where i would eat say fifty grams of carbohydrate from white rice. She would eat the same amount. She's a good thirty or forty pounds lighter than i am but she would still her blood. Sugar would over a two hour period of time. Never really get above about one hundred and fifteen hundred twenty you know. Throughout the course of that whole experience was mind would top off round one. Ninety one ninety five. I would then suffer. Really cloud rafic crash blurred vision cognitive problems. I mean i was. I was kind of a disaster on that. And so this was you know it was cool in that it gave a little bit more concrete explanation for what i'd seen clinically. Which is that. This person seems to run great on carbs. This person doesn't and you know here's there's kind of like an actual yeah and just to be clear. You're not diabetic. North korea pre-diabetic new. But i think if i ate carbs pretty consistently i would get there rather rather rapidly. Yeah or or the minimum. I would suffer a lot of deleterious health effects. Light like a a vision problems and and whatnot. Yeah yeah so. How do you explain now. Like metabolic flexibility. Like how does it cure or is it just something that some people have in some. Don't i not entirely sure. I think that there's multiple factors at play here for sure. Genetics is a piece of this. People who have more of the emily's gene more frequency of the emily's gene seemed to do better with carbohydrates. They seem to digest them better but they also have a more favourable insulin response. It seems to keep the insulin. Or the blood glucose levels within tighter parameters and. Here's an interesting thing that i For me it was kind of this. This pretty deep inside. I don't know if it is for other people but an individual like myself to have good blood glucose levels after he reasonably low carb like probably below fifty grams of total carbs. Day sometimes more. Like if i'm really active or whatnot but it in that situation. Abbott pretty consistent blood glucose response throughout the day. People were very metabolic flexible or very insulin. Sensitive they looked like i look like eating significant amounts of carbs. And that's really the big difference there in the people who eat significant amounts of carbs and don't suffer the blood sugar crashes which then lead into the over over consumption of food writ. Large i think is where we kind of see the distinction between folks Twenty years ago. I was definitely a bit indie. Insulin hypothesis camp. I think over the over the course of time. I've i've come to the conclusion to. Yeah chronically elevated. Insulin levels are definitely a problem but insulin. In and of itself is not the primary driver of of Say type two diabetes and insulin resistance and whatnot you kind of a classic gary tops approach I don't buy into that but at the same time ni- fully on board with say like it fits your macrophages crowd. That will just say so. Long as composition doesn't really matter you just need to keep control of your portions and a free living world free living population. How you keep control of portions is really important. Not that many people have the discipline or the neuroses to do basically like a figure competitors lifestyle like that. That's a big lift for a lot of folks and so finding a way that people can spontaneously match caloric intake and output. I think is kind of where the ticket is. And that's where people kind of find own their their metabolic flexibility optimum belay yet. He asked a really good question. I did a poor job of answering it at you. Know what is metabolic flexibility. What goes into a defining it genetic so definitely a big piece. The gut microbiome appears to be a big piece. The caveat to that is we know it's important. I don't think very many people have any idea what to do to improve that. Like probiotics works for some people pre baddeck fiber work for others and for some people all of those absolute disaster and do nothing. So i think there's a lot of Charlatanism that goes around the gut microbiome. We know absolutely that. It's important. But i think the only thing that we can really hang our hat on is if we do something and has a clinical outcome of improving gut else and improving metabolic flexibility. That's great but we're not really at a great predictive place with that like i. I think there's a lot of goofiness that on the testing and whatnot. There is some lesser known or considered things like iron overload particularly in in men or postmenopausal women excess iron accumulation in the body is a pro oxidant in that pro oxidative status can increase inflammation and increased inflammatory state Degrades insulin sensitivity and by extension the Metabolic flexibility so. There's some big picture things that we know. Feed into metabolic flexibility and again. I think that we have burying degrees of control over those different lever.
