I used to be on a diet since last year, but I have stopped months ago. Lost 10 kg and now my weight is 58 kg with a height of 175 cm.

No more healthy diet or whatsoever. I tried to avoid eating fast food though and I still take fruits, veges and brown rice. Fattening meals sometimes unlike last time. I even go for supper. Has been like this for 4 months, but my weight and body figure still remain and look the same. I know I gain weight easily but not this time. Is it due to a higher metabolism rate of mine?

I guess so. Thanks for the feedback anyway.
