Ciao Marco, I have the same concerns with my cholesterol, I am really super impressed with the changes you get with more attention and fibers. I really like the attention to detail when you write that on low carb days getting the fibers is really difficult.

I am in no way a lipidologist but showing such a trend with a change in diet might be a clue that you are on the high absorbing side of people. I know that testing some sterols might help understanding this but again I have no expertise. (Also ezetimibe might be a strong tool if you are on the high absorbing side).

I am disappointed for you for the 100k after such progress...

Also I am back from a trail in the Dolomites and I had a lot of time to think about nutrition during the "race" since I was very slow, I have to shoot you a DM for something personal...

Very interesting use of normalized HRV in the case of an energy deficit 👌🏻

Since vagus nerve stimulators have been reported to increase HRV, can you address using transcutaneous vagus nerve stimulators, prior to aerobic exercise, and potential

benefits?

I purchased HRV4 Training, but I was under the impression that it would help me train my HRV to be better, perhaps through biofeedback. I had an ablation in 2021 for atrial fib, and ever since my HRV has been very low. If I'm not looking to improve my athletic training but rather my HRV itself, did I buy the wrong app?

hello April, please feel free to reach us at hello@HRV4Training.com and we can try to help. HRV4Training is meant to be used to assess your baseline physiology, and capture potential changes in your baseline / resting physiology associated to different practices, for example slow breathing, which is the type of exercise you might be interested in if I understand correctly. If you have an iPhone, the app you are looking for in the context of doing that exercise, is HRV4Biofeedback. HRV4Training can / should still be used to evaluate baseline changes in resting physiology, as assessed first thing in the morning, which is the optimal time for this type of analysis: https://marcoaltini.substack.com/p/monitoring-hrv-why-the-orthostatic

Non-invasive vagal stimulation improves measures of cardiorespiratory fitness and attenuates inflammation, offering an inexpensive, safe, and scalable approach to improve exercise capacity (reference available per request). To determine the utility of the Pulsetto transcutaneous vagus nerve stimulator (tVNS), I performed well controlled daily aerobic workouts with vagus nerve stimulation for 7 days and compared outcomes to 4 months of similar, daily workouts. Result for 5 indoor 2 mile treadmill combined with 2 mile outdoor workouts and 2 HIIT elliptical workouts established 7 consecutive personal best times. Heart rates for indoor/ outdoor runs averaged 80% of heart rate max and 85% for HIIT, by design.
