Where are you getting this number? Over 27% body fat is a health risk. For an active but not muscular individual, 30 BMI is at least 33% body fat, likely higher.
There's no such thing as "ideal". From what I understand from the research, more fitness is correlated with better health outcomes, even up to advanced to elite level.
I recommend trying out a number of different exercise modalities and schedules and seeing what you enjoy, what makes you feel the best, and what fits into your life.
If you're hoping for multi-trillion dollar multinationals to fight political battles on your behalf, you're playing the wrong game.
Either your country is a democracy where people get to choose what their government does (aka, a majority of people want these invasive policies), or it's illegitimate and should be treated as such.
