Sunday Supp: Caffeine and Ketosis

Chad himself has a question for Eric on this edition of the Sunday Supp. Chad wants to know Eric's opinion on caffeine and how he interacts with it while in ketosis. If you have listened for awhile, you've heard Eric share his story about the accidental caffeine overdose that put him in the hospital. Needless to say, Eric certainly has an "interesting" relationship with this stimulant. 

The importance of self-experimentation to determine how your body reacts to caffeine.

What biomarkers can tell you about your genetics and caffeine.

Should you be concerned about caffeine's addictive nature?

And how ketosis can actually decrease your dependence on caffeine (it's all about that beta!)

Grab your favorite cup of energy and tune in to hear the Biohacker talk about his caffeinated experiences!

Chad: 00:05 so we're getting a lot of questions regarding the proper way to live life in ketosis. We have you covered in our mid week mini series called Sunday subs. Every Sunday we'll have a quick supplemental episodes where we answer your questions on all things Keto. So our question today is actually a selfish one on my end. The question comes from me, Eric and I'm curious about caffeine because I like caffeine and I, I want to know what my relationship with caffeine should be on a proper ketogenic diet. So my question is what are your thoughts on caffeine? How much should we be using, how, what's the proper way to relate to [inaudible]? Again, when we're in Ketosis, caffeine,

Eric: 00:46 caffeine can be my best friend, but as you know Kathleen put me in the hospital, talked about that caffeine is not my friend anymore after you put me in the hospital. That was a dumb mistake on my part, but no, I'm a no. Caffeine is still my friend. And and you know, obviously it's a stimulator of the central nervous system and it, it has it's purpose. It really does. And I wish I could say I don't take caffeine, but I use caffeine on certain training days are using erase. Um, as you know, I think we talked about before I tested caffeine. I literally in the beginning I self experimented. I laid in bed with him with the blood pressure kit on me with a heart rate monitor. I took 300 milligrams, then I went up to 500 milligrams and I went up to 800 milligrams to see if.

Eric: 01:35 No, no, no. I would separate days several days because I wanted to see if it raises my heart rate. OK. And My blood pressure. And then I actually did it while I was training on the first day, 300 megs and then 500, then 800. And I was really amazed that he didn't Jack my heart rate up at all. I was like, what the heck, my blood pressure and stuff. So what's Kinda cool. Then later on I had my snips done, my genetics done and I actually didn't know this, but I actually have that, what they call a c, y p a two. That means I'm homozygous in that snip, which means I'm a fast metabolizer of caffeine and the opposite, it ends with like a one to one half, one half and it means that you're a slow metabolizer of caffeine if you have that snip cause I'm, I'm homozygous on that.

Eric: 02:29 But if you're not and you have the slow metabolizer snip, then be careful and you don't know that because even in hypertension and heart attack or you know, non fatal ones, there is an increase of slow metabolizers of caffeine and I'm a fast metabolizer and when I got put in the hospital, but it probably really helped me to move it through and it does have a short half-life. Let me think. Six hours half-life for caffeine. But no, I, I think a lot of lot of you use it. I don't think there's anything a better, you know, that that's illegal stimulant. And I, I, I think a lot of people, you know, use it. A lot of those that I coach. You drink coffee.

Chad: 03:18 No, I do. I do. Yeah. I have coffee in the morning.

Eric: 03:21 You do and you know, and there's some that that, that don't metabolize or they get headaches from caffeine and they have those issues and I've been one of those before race. I'll back off for two weeks to, you know, to so, so I'm not, I get it out of my system so I get a bigger bang from him, click, but there's been studies I've read and done some research and it really doesn't. It doesn't work that way. I was really surprised they tested some endurance athletes him and didn't take them out of caffeine and they had the same production, wattage and everything else. Maybe it's a placebo effect when you think you're away from and I'll send you take it and you get this placebo effect too. But no, I. Caffeine is a stimulant. If it gets you through your workout some days, uh, and some days you just need it. And that mental cognitive it does it. It's not really an energy producer, it just, it works. The central nervous system. So it's going to stimulate you wise and you just focus better.

Chad: 04:16 Yeah, I know a lot of people are, are worried or concerned about the addictive nature or dependency. Is there anything, I mean, do you, what are your thoughts on that and what do you recommend to people if they're worried about

Eric: 04:28 people that become where they gotta have their caffeine. OK. And I don't know, you know, it, it, it can be addictive into where it's a mental issue with you that you think you need that to pick you up, you say, and most of the time it will pick you up and tell you you have to make that decision is how dependent do you want to be on something? I use it on days that I feel like I, I just needed to get through a good workout and so I'll take a little bit of caffeine and then some days I don't and I have a better workout and some days I'll need it now just with the Beta as far as being cognitive enhancer stimulant, almost like that. Uh, I find out any caffeine during the day at all, just just on training. Sometimes it's my opinion, a lot of my opinion on it.

Chad: 05:13 It's subjective to right for everybody, so I think some self testing has to be done a little bit maybe to kind of find out where your thresholds are, how you metabolize it, how it makes you feel, all of that kind of stuff. Because for me, I mean [inaudible] megs is about a cup of coffee and I drink my cup of coffee in the morning over two or three hours and I have to or else I will be very upset and mess. I could take. I could take 300 milligrams, right? No, no. I'm serious. I would feel nothing. You can say. Oh, you've been on it so long, you know? No, it metabolizes. I don't. I never really feel a pop from caffeine. I just get a little

Eric: 05:58 cognitive in a little more focused. Maybe it's placebo that I'm thinking, but I can honestly say, and even in other drugs because of the snip my liver metabolizes drugs really fast medications and things like that and even in pharmaceutical, if as a pain pill that I've taken, I have never. And I've told my people that's I have never got what they talk about, a buzz off, a pain pill or even strong pain pills that euphoric or any of that feeling I never interesting was awesome. Yeah. And just to be safe, test it, you know, when you get your jeans, look for that snip if you're a slow metabolizer, beware.
