I've been on a Diet for over 5 months now.  Most people seem surprised when I tell them.  "You don't need to".   They all seem obliged to give such a supporting remark but in the end it's not very supportive. Well no, my BMI was still ok. But I gained over 6 kg in less than 3 years so if I didn't act my BMI wouldn't be ok anymore.  There was a clear trend that I had to stop and even better...
