I'm not sure "forcing yourself to the healthiest diet/lifestyle ever" is actually a good idea, because there is no one healthiest diet or lifestyle for everyone at all times that we know all the details of. IMO much better to aim for simply "healthy" or "very healthy" as a habit you stick to long-term.
