Reached goal- help!

[haveyouopenedyourbowelstoday]

In June last year I weighed 17 stone 4lbs.
Im 5ft 8".
Today (at nearly 53) I'm 12 stone 7 which was the target I set myself. My BMI is 26.5 but I'm afraid if I loose any more it'll come off my face and boobs and age me.
What I need please is advice from those who managed it is how to stay at this and not put it back on.
Oh and I've done it through Intermittent Fasting and low carb/very low fat.

I maintained my target weight by sticking to my maintenance target calories and tracking them on MFP. Congratulations on reaching target.
