Like Leticia I think you just have to accept that dieting isn't going to work. Once you start putting on weight & can no longer lose it reasonably easily, as when younger, you have to change to eating smaller meals, and no snacks, for life. It's depressing to realise this to start with, but after a while it becomes the norm, and easier to stick with. I save my breakfast for mid-morning toast with coffee, and therefore it feels like having a daily treat. I have a very light lunch because I've had a late breakfast, then an early, very simple, evening meal. Because I don't have much will-power I allow myself as much fruit as I like at any time of the day or evening. This works for me and has to be the way I eat for ever. I have managed to get down to below the upper end of my BMI, and reckon that being a bit more nimble & flexible, and able to cut my toenails etc, is worth the effort.
