I think science has given people with bodies that don't tolerate restriction an out in the form of Ozempic. I've seen a few of my friends go through it and it's scary effective. It's not a forever solution and you do eventually have to form better eating habits to maintain your new weight but being overweight is so damaging to your body that it's not worth the fight if you've been trying and failing to lose weight via the usual channels. Just cheat and then work on not putting it back, your knees will thank you in 40 years.

Not bad for the wallet either. My local shop sells potatoes for USD$1.61 for 8.8 lb (that's AUD$2.50 for a 4-kilo bag) which provides bang on 3000 kcal.
Looking at a 4 kg bag it would be so hard to eat anywhere near one bag every day, I just could not imagine getting through that volume.
IIRC from last time this was posted, the hypothesis for why most people felt really good on this diet was a nutrient deficiency in most diets that's addressed by potatoes
Potatoes are definitely not a low calorie food. According to the USDA, potatoes are .77 kcal/g, while apples are .58 kcal/g, oranges are .47 kcal/g and tomatoes are only .18 kcal/g. Sorry, but potatoes are too good to be low-calorie.
It don't work, I eat 1 meal a day with either potatoes or bread and I maintain the weight. I found instead that reducing my carb intake was the only way I could consistently lose weight.
