Well, they're probably realizing there are so many fat people out there, they'd better profit. It's like diet coke and other diet products, many fatties buy them. There are 2 types of fatties, one is "i want to lose weight but it's haaard/reeeee" and the other is "FUCK DIETS I'M A FIERCE WOMYN/haes"...so the first buys diet cereals to show it's trying, then goes to the gym for selfies, and rewards itself with a bigmac and fries and -diet- coke. The second one buys them because it has to show it's naturally fat despite a -healthy- diet ,so eats cereals and fruit before stuffing its face all day with,...well, everything else.
