Then you mentioned metabolic efficiency. I think some people might be familiar with that term, some perhaps not. But the way I understand metabolic efficiency. Is that your you teach the body to use fats, by may be doing long, long bouts of cardio, Maybe. Lower in carbohydrates a bit. So teaching the body to tap into its fat stores for certain periods of training and then you also teach the body to utilize carbohydrates by supplying carbohydrates immediately after training and before training, you teach the body to use ketones. And then you use them at the appropriate time as opposed to just deciding that one of these fuel sources is good and all the others are bad or dispensable. Do I have that correct?
Even I'll do you mean from Bob? See, Bahar as formerly of USA Triathlon. Is the guy that kind of Came up with the the concept of metabolic efficiency. But yes, you're absolutely right. I mean low intensities of exercise or just day-to-day living we shouldn't be tapping into our carbohydrate fuel sources, extensively that that's that's for higher intensity work or you know, the fight-or-flight needs of stress, you know, if you know athletes or any individual has a high carbohydrate diet, they're going to start to become Bo's to utilizing that fuel source. Preferentially now a low intensity that can be problematic, certainly for an athlete because if they preferentially use carbohydrate a lower intensities. When the, when the exercise demand goes to a higher intensity, they've already exhausted their fuel stores, you know, they can't draw upon fat because the oxidization of that, that fat is just too slow. So they're essentially now become fatigued because of the variety utilized, the carbohydrate stores. So what we try to do, yes, through diet. Population. And a little bit of exercise manipulation is, as you say, teach the body or train the body, to preferentially use a specific fuel source fat, obviously at lower intensities and carbohydrate at high intensities. And we look at specifically the crossover point between the two tells a lot in terms of how an athlete is ultimately, how their metabolism is working. Well,
again, I am smiling because I love this because it's grounded in something real and scientific, which is that we have these different fuel sources. The body can adapt to use any number. Of them are one of them. I think most people are looking for, that one pattern of eating that one pattern of exercising, that's going to be best for them or sustain them. And they often look back to the time when they felt so much better switching from one thing to the next, but the adaptation process itself is also key, right? Teaching the body.
