Thanks LC sponge for your advice ,
I will try to avoid eating sweet thing and eating rice during fasting Ramadhan) eventhough it rather difficult .

In Indonesia normally during fasting we eat early in the morning around 04:00 AM in . and after that stop eating and drinking until 18:00 hrs , we break the fast +/- 18 :00 hrs in the evening .

Since this become my first Ramadhan without eating rice and drinking syrup I my hv to modify eating habit little by little , probably I will take more fruits . And at the same time I my hv to check my keton level to make sure that I still in Ketosis mode.
Thanks anyway for your advise
