Strong correlation between resting heart rate and carb intake

[PointBreeze]

Has anyone else noticed a correlation between net carbs eaten and resting heart rate?  I have seen this correlation over and over again over the past several years.  When I keep my net carbs below 100g/day, my resting heart rate drops to the low 60s.  When I eat more carbs, particularly processed carbs, my resting heart rate starts rising, going up 7-10 bpm.

What I really notice about this is that it really depends on what I eat after 6 pm. Going out and having pasta, wine and dessert is a killer, and my sleeping heart rate never gets below my resting heart rate. 

My best dinner for low RHR is baked salmon and a kale salad (Eat Smart pre-packaged) eaten between 6 and 7 pm if I'm going to bed by 10 pm. 

I haven't checked my total carb intake in relation to RHR, but I will now!

I havn't noticed specific foods effecting my resting heart rate but sleep sure does, lack of sleep whacks my RHR 😞

I know this is an old thread but yes, I have seen this over and over again. The lower my carb intake, the lower my RHR. The higher it is, the higher my RHR gets.

I just googled this very issue.  I'm bradycardic through the night and less than 63 RHR when resting but awake when I'm eating low carb but then if I eat carbs, up my RHR goes and my fitbit records me as doing zone minutes when I'm just doing normal stuff, not deliberate exercise.  I'm a bit concerned about it because it's one extreme to the other and I'm not sure whether it means I should or shouldn't eat carbs.

Hello @DebraAW 

This would be best discussed with your healthcare provider. They can check your heart rates and help you make any necessary dietary changes.

It's interesting that you've noticed a correlation between your net carb intake and resting heart rate. Many individuals report similar observations, as the body's response to carbohydrate intake can vary, particularly with processed carbs. A lower carb intake may improve heart rate variability and overall cardiovascular health, while higher carb consumption, especially refined or processed carbs, can lead to fluctuations in heart rate, possibly due to increased insulin production or changes in blood sugar levels. However, the relationship between diet and heart rate can be complex, and it's essential to monitor other factors like stress, sleep, hydration, and exercise for a comprehensive understanding. If you're interested in tracking these changes more precisely, integrating this data into a health-focused platform like SkyNode could provide insights into patterns and correlations.

I noticed the same it dropped by 7 points

Interesting.  I have specifically not seen sleep effect my RHR.

It’s really interesting that you’ve noticed a correlation between net carbs and your resting heart rate! Everyone’s body responds differently to different macronutrients, and it sounds like a lower-carb intake works well for you. It’s always helpful to track and find what works best for your body!

Thank you for the info. I was very interested in this question and was looking for answers.

While not particularly accurate, I think of carbs as sugar that when complex, "good", is many chained together in a string. While "super processed" is short chained, sugar itself a single piece. You don't eat sugar before bed because it winds you up, same with saturating your system with simple carbs. Complex unwind more slowly.
