Dieting is pretty simple, maybe not so easy.
You can eat any food you like (in small enough quantities), as long as you are hungry 100% of the time, you are doing it right. You should be slightly hungry even after a meal.
To make it a little easier, try small meals or snacks every so often, as long as you are always hungry. Exercise helps, but is not essential or even important, but it does increase the amount you can eat while remaining hungry.
I’ve lost about 20 lb with this regime and now I’m 170 lb at 6’0” tall. I could lose more, but 170 lb is my target for now. The lower you go, the more hunger you must endure, it gets harder & harder.
“as long as you are hungry 100% of the time...”
May work for some, but not for me. Being hungry and grazing made me cranky and stalled weight loss.
Snacking kept my insulin high. Insulin blocks fat burning.
I would rather eat normal real meals most of the time and fast occasionally. No snacking was a key for me to allow time for insulin to return to baseline.
There are many useful strategies on YouTube — see Dr. Jason Fung, Butter Bob Briggs, or the OMAD One Meal A Day guy.

This is the 95% failure diet right here. If you're hungry all the time, you're not happy and most fail. YOU may be strong enough to endure a life of constant hunger. But that is poor advice for most. Also, if you're constantly eating, you're constantly in fat storage mode. This is why most diets fail.
