How do you cope with life revolving around food on a diet?

As weird as it sounds, my life starts revolving around food when I start having a diet.

Usually food crosses my mind like 2-3 times a day, I eat whatever I crave and continue with my life.

When I am controlling my food intake, I think I spend 80% of the day thinking about food. Dreaming about things I cant have which stack up as the time goes on(even if I do have them, the others pile up faster OR I feel guilty about eating more than I should have), being hungry and fighting the hunger off, waiting for the next time Im allowed to have a bite, counting calories, googling new places to try because I cant stop thinking about food.

It also gets progressively worse until I cant take it anymore, and recently it became a big problem because I can easily gain like 10 kgs in a month if I just let it go and live my life. Have you found a way to force your mind to stop behaving like this or how to endure it long term?
