@gedeonm@mastodon.social used to mean "bad". Both LDL and HDL go way up when fasting. Most low saturated fats are incredibly unhealthy because they are basically plastics. The few other low saturated fats (olive oil) will still turn into plastics, just take longer, on the order of ~4-6 months depending on storage. https://www.youtube.com/watch?v=rQmqVVmMB3k It is low saturated fats that cause heart attacks, not cholesterol. Keto diet is extremely effective because it gets the body primed to burn fat for fuel, rather than carbs.
