Interesting topic. I started to track a lot of metrics from:

- number of calories ingested and the micro/macronutrients

- number of sleep hour

- monitor heart rate

- monitor heart rate variability

- number of hours doing sports

- blood test results

- waist size

- number of steps per day

- ...

It helps me to understand my body's reaction better. For example, I did around 9 hours of sport per week (strength, running, hiking) for the last couple of weeks. I didn't change my calories ingested. I feel hungrier, and I need to do more naps, even if I sleep 8 hours per night. Also, my heart rate variability is lower than usual. It might mean that I overtrain and I risk injury. My body does not adapt yet to this training intensity.

But sometimes, it's harder to understand what has driven the results. I started to take Omega 3. But at the same time, I also started to run more. We know that running more impacts your heart rate; it decreases bpm. But it's also the case with Omega 3. So in my case, it is complicated to know if sports have a more significant impact on my heart rate or if it is Omega 3. Both also take time to have effect.
