Is there any evidence that apoB lowering medication can offset accelerated atherosclerosis caused by endurance sports e.g. ultrarunning? With Peter's high METs output per week and rucking it would seem plausible because rucking for multiple hours would have similar intensity to mid-pack trail running (aka glorified bushwalking). Background - After reading Outlive I went for a screen and shocked to find a low CAC score at 40 years old. 8+ years of non competitive ultrarunning, and with a history of acceptable lipid levels throughout this period to boot. Now wondering if I medicate to drop apoB to the max will it be wise to go on full day adventure runs in zone 2? Not current GP will not prescribe medication due to good lipid profile.
