Besides asking for studies that may or may not be there, what was your experience with this? I hadn't heard of this before.
Not OP, but I've lost >100 lb. three separate times in my life, so I suppose I qualify.
It affects you in ways that are analogous to overindulging in adult entertainment.
You need higher peaks (e.g. more salt) and, in my experience at least, you gradually lose the ability to pick out subtle flavors.
You start to prefer food that you can scale as you see fit. Lots of rice. Lots of potatoes. Lots of popcorn.
They charge a fee if you do that in my county, and the "flat rate" is dependent on the size of your bin, as a proxy for how much trash you generate. If you have more trash than fits in your bin you have to buy stickers for the extra bags to pay for them to be picked up.
Where are you? I'm in the US
Garland TX, a suburb of Dallas, has a flat rate per bin, with free curbside large item/landscaping waste twice a month. Throw your old washing machine on the curb and move on with your life!
My mother in law, lives about 50 miles outside the DFW Metroplex and pays a flat rate based on the average of her trash usage. She rolls 2 bins up to the curb once a week. She can put more out and they will take it, but if she consistently puts out more trash, they will bill her extra when it comes time to renew every year. The guys on the trash truck keep a rolling tally of your "usage" and then the office works out who needs to pay more if the customer skews towards more usage than they signed up for.
I live in Europe now and moved here last year. I pay $12 PER PICKUP for residential trash here in the Netherlands. The catch? They pickup that bin ONCE every TWO MONTHS. If I want to throw more stuff away, I need to somehow transport all my trash to the local dump, pay a fee, and unload and sort it all myself.
On a more positive note though, recycling plastic is free. Some of my neighbors generate an entire large bag of plastic every day. My wife and I fill up one bag a week. Our "normal trash" bin is usually half full when it's time for pickup.
Pricing for waste is largely dependent on the municipality as well here in the Netherlands.
My household typically throws away 3 or 4 ten gallons bags per week leaving the bin maybe a quarter full. The neighbors across the street are constantly having food delivered and routinely fill two bins.
In most cities there are usually many options for restaurants nearby and Uber Eats for anything further out. For everyone else there's McDonalds and friends: https://www.qsrmagazine.com/content/ranking-top-50-fast-food...
