Keep Track My Calorie Intake

I started to use a calorie counter available at MY Fitness Pal to help me keep track on calorie counting. I know my weight have increase since this month. But I haven't find out what is the reason yet. I suspect that I might be taken too much of oily and high calorie food recently. Luckily, I don't need to buy a calorie counter just to record my diet calorie. I have the best and free calorie counter provided by My Fitness Pal. I hope that I could keep track and control my calorie intake with the help of it.
