For the past 25 years or so, my diet approach has been 'Lose the weight as quickly as possible by restricting this or that or the other thing"
Well, that's frustrating because eventually you want one of the forbidden items. and then the floodgates.
So, I changed my goals. My goals now are to move SOMEHOW every day for at least 40 minutes, to do at least one strength training item per day and to eat about 2,000 calories per day. If I run/walk for over an hour, I add a few more calories in. I can usually make room for an indulgence or two every day.
It's not perfect, but it works for me.
I'm feeling happier and more comfortable with where I am. Just watching now, to see if this is the honeymoon phase. I hope not.
