Peter Attia recommends a three-month trial of Continuous Glucose Monitors (CGMs) for most patients to provide significant insights and act as a behavioral tool.

“I use the Dexcom G6.”

“I cracked my first one doing heavy DLs, but otherwise never take it off, including everything else with weights.”

“I’m heavily biased to Dexcom because I place a huge premium on accuracy and reliability (over cost).”

“It's not just a tool for ketosis...everyone needs one of these things (IMHO).”

“I'm so freakin' obsessed with CGM...can't imagine life without it.”

“Hell yes I do and whenever I see a kid with T1D wearing their G5 I show 'em mine.”

“I think the only reason I didn't eat that cookie that was bigger than my head is because I knew I'd have to look at my CGM data after mmm I mean so there is no more powerful behavioral tool for me than my CGM because in the end I'm kind of a competitive person internally much more competitive internally than externally by the way and I just can't stand to see spikes of glucose it just drives me nuts”

“the first is it's a great way for me to control my behavior and I know it's tempting to want to believe that I'm somehow impervious to the forces of bad food but the reality is a reality of it is I am NOT”

“the g6 along with the aura ring which I've talked a lot about are these and I've worn every wearable that there is but they're the only two that seems sticky enough that I can't stop wearing them”

“What exactly are you looking to achieve and monitor with your blood glucose monitor your CGM your g6 would you another product if you probably you love I love the g6 and I'll talk about it all day long”

“I wear a 24-hour glucose meter so kind of a weird guy for almost four years I've been wearing a glucose monitor all the time so it measures my glucose 24/7 at one minute increments and out of say 365 days in the year I'm easily wearing it 330 days of the year”

“my 90 day trailing average glucose under these very tight conditions shows an imputed a1c of 4.5 to 5.1 depending on how tight my nutrition is”

“I consider it to be one of the two most important devices that I wear and I wear it pretty much all the time”

“I would say three hundred to three hundred and thirty days a year I am wearing my CGM”

“well I've been wearing one now for almost three years I think after that flight you said well you got to come in one day and and well shoot the breeze and within like a week I was wearing one and I've never stopped”

“I've been wearing one of these things now for probably three and a half or four years so for me I'm not gaining new insights daily maybe every week I get a new little insight so maybe it's 10% insight related but the behavioral piece it's basically a walking Hawthorne effect we have pretty clear metrics with where we want to be both in terms of average glucose in terms of standard deviation of glucose which we use as kind of a proxy for insulin and then in terms of the number of times you have excursions over 140 that becomes kind of another metric you want to avoid and so it absolutely curbs my behavior when I am wearing it which is most of the time I probably 300 to 330 days out of a year I'm wearing it definitely dials my behavior in absolutely”

“but I also find that the CGM for me is one of the its along with the my sleep ring it's the stickiest device I've ever used whereas any other wearable I've ever used it's like after two weeks I don't want to wear it anymore because I've already learned what I need to learn like I know how many steps I take why do I care”

“the same thing with like the continuous glucose monitor I just it's hard for me to imagine I used to not know my glucose in real time so there a couple things from it right the first is it's a great way for me to control my behavior”

“I think the only reason I didn't eat that cookie that was bigger my head is because I knew I'd have to look at my CGM data after”

“And I just can't stand to see spikes of glucose.”

“I think the only reason I didn't eat that cookie that was bigger than my head is because I knew I'd have to look at my CGM data after.”

“So there is no more powerful behavioral tool for me than my CGM?”

“for my last 24 hours i've averaged about 90 milligrams per deciliter and my variability has been about 9 or 10 milligrams per deciliter or my standard deviation my peak level has been let me see i have to go back and look my peak was 102 and by extension then i've had no peaks above 140 that's going to come up later later on so obviously if my peak was 102 i was never above 140 and my nader um was 77 so range of 77 to 102.”

“i i'd like to believe that there will be a day when when you go to your first visit at your doctor they actually you know or prior to your first visit with your doctor they send you they mail you a cgm and you wear it for 30 days and that data is is looked at by your doctor and your doctor by the time you arrive in the office he or she has that information”

“i think everybody deserves a three-month trial of cgm again notwithstanding a handful of patients who i think have contraindications”

“I've been wearing cgm for almost six years it never gets old to me i continue to find insights that you know just provide value and more than anything else it's really the behavioral tool”

“we use CGM a lot it's a great tool for you know when we have questions it provides answers you know when we we could sit here and look at a person's ogtt and you know in some cases it's just a slam dunk like this person is is super metabolically dialed in in other cases it's a complete slam dunk this person has Type 2 diabetes um you know by ogtt criteria even if not by A1C criteria but there are a lot of people in the middle and this is a great way that we can glean more information and really kind of dial in our treatment for them”
