an insulin pump is a good metaphor; insulin as a hormone has a lot of interactions and the pump itself, if not wanting to unalive its user, should (most do not) account for external variables, such as: exercise, heart rate, sickness, etc. these variables are left for the user to deal with, and in this case, is a subpar experience in managing a condition.
Not sure why you’re being downvoted, this is one of the best takes here. It sits squarely in the realm of evidence where the majority of these comments are anecdotal and they don’t translate to population level studies.
The problem with red meat isn't meat per se; all meat has saturated fat, some more than others. Reducing LDL cholesterol (reducing CVD risk) means increasing fiber and reducing saturated fat, and if someone chimes in saying that it's not casual, we have an excellent mendelian randomization study that gives us a pretty good link [1]. All plant-based meat alternatives, including cheeses, have high amounts of saturated fat from coconut oil, which isn't very good either.
