I don't even think the fast food industry wants their support anymore. $5-10 per meal @ 35% margin from a fatty buying fat shit that's getting more expensive for them to process every single year, and harder for to increase prices on items(fatties will bitch if their mcchokings go up $1 while normal people don't). Or they can get $15 per meal @ 50% out of a normal sized human who would ordinarily be lined up at whole foods/fast casual joint ordering food that's made with inexpensive vegetables, wraps, lentils, and normal sized beverages that you can sell for more than $1. Even your meat products can be health washed so you can price guilt the shit out of people, can't do that with the fatties looking to score a pile of $1 burgers and a 20oz soda.
