LCL-C doesn't appear to be a great marker. My three big points are:

• There is research that shows that the average person coming into the hospital with a heart attack has LDL-C that is lower than normal.
• LDL discordance is fairly well studied, and it shows pretty clearly that low LDL-C is not a marker of health.
• There is some research that shows that elderly people with higher LDL-C have lower mortality.

It's also pretty clear that pharma is making billions of dollars off of statins and are hugely behind the message that elevated LDL-C is harmful and should be treated by statins.

Statins do have an effect on CVD, but it's a minor one when looking at prevention (NTT is around 100-200, so if 100-200 people take statins for 5 years you would prevent 1 heart attack).

10 miles of walking is achievable on keto, though it may take some time to adapt. I do 10 miles running fasted fairly often on a keto-adjacent diet.

Weightlifting is different; it depends on what you are doing. See /r/ketogains if you want more details.

Somewhat surprisingly, it's possible be at the low end of the spectrum and still be quite insulin resistant; it's known as "metabolically obese normal weight".

I've always been light but a few years ago I started having really bad energy issues after carby lunches, presumably due to low blood glucose. Getting rid of the carbs fixed that for me.

Fyi, you lose about 2.5% of your oxygen every thousand feet up.
