I want to lose weight!

I'm so damn fat now... i dunno why this is happen to me... since i goin to Kuching, i gain a lot of weight.... currently, my weight now is 66kg!!!! I dun wan to believe it,but its true... I've check my BMI juz now..its shows tat i'm overweight.. it was 27.. normal BMI is 24.9... OMG...i wan to do some exercise n control my appetite! Have to calculate the calorie also... According to my age, the maximum calorie for a day was 2000 calorie... so,tat means i have to watch wat i eat everyday.. it wasn't so hard actually but the 'exercise' part was the most hard activity... hehehehe... but i have to do it no matter wat.. so, Chayo2!!!!
