I've recently started doing 23h fasts. It's the easiest diet so far. As soon as I come back from work, which is around 5pm, I eat whatever I want. Then no eating until I come back from work next day. It's also nice not to think about food all day.
Assuming you do not have a metabolic disorder of some sort (which may be the case, but you'd need a doctor, not the internet, to diagnose it):
Try switching to fat+protein (and zero carbs), and see if it keeps you satiated longer. Many people find that carbs make them hungry again quickly, even if eaten with fat or protein.
That's not a good thing, btw. It shows you're addicted to constant blood sugar hits. Getting through a day or two of agony and fasting would probably help you out in the long run.
I've forgotten the details, but I believe the described pattern is characteristic of some metabolic disorders. Considering that, I'd recommend talking to a doctor before going straight to fasting.
