if you can handle it, go vegetarian for one month. no sugar drinks at all, no carbs, no meats, no fats. you caeat as much veggies as you want, save corn or high sugar/carb veggies. ie no potatos, no rice. you can use olive oil for flavoring. balsamic vinegars and mustards. italian dressing, but no french/ranch.
you wont be hungry, it’ll clean out the gunk in your intestines, and if you are normal active you’ll drop 20 pounds at least, probably more.
if you stay on a diet like this long enough, and it varies by person and how overweight the are, eventually you’ll stop losing weight and that will be your ideal weight.
I was a vegan vegetarian years ago til I put on too much weight.
