How big is the fast food industry by 2030?

$1.2 trillion a year by 2030 on my call, growing 4.9% a year: more restaurants, more countries, more ads aimed at kids, the same cheap product sold everywhere, day and night. The obesity bill runs alongside: 2 billion people overweight or obese in 2020, 2.5 billion in 2025, 3 billion by 2030, more than 1 in 3 humans.
