Good news, your body hates maintaining "useless storage" and if you keep them empty, your body won't replace all the dying adipocytes ( they get replaced every few years ) so you will have fewer of them.

Keeping the now-useless adipocytes in the same number is a waste of energy ( fatties have a much higher basal metabolic rate than a non-fattie of the same age, height and genetics would ), and wasting energy like thst used to be very disadvantegous for survival.

Conversely if you keep overeating, your body will make more even into adulthood. It's a vicious cycle up to each person to make the effort to break.

It dosen't change the fact a caloric deficit will make a fattie lose weight, but it will influence how much hormones adipose tissues secrete to try and influence the fattie to eat more.

Harder to the mind, but won't change the numbers involved, despite what proponents of Cosmic Fat Osmosis claim ( the "fat people don't eat more, their body just holds onto fat" crowd ).

Thankfully humans have a brain capable of delaying gratification and make the choice to endure discomfort now, for better outcomes tomorow.

I used to be alot more sympathetic to the idea of government intervention to manage people's food consumption, but after 2 years of pseudoscientific sanitary circus :

For the love of God never give another inch to the government or they will make everything miserable for everyone because somewhere, a fattie will overeat if people are allowed to make their own decisions.
