If you are serious about losing weight, here is what you should do:

1. Eat less junk/fast food (maybe only once a week as a treat only)
2. Cut out all sugar in drinks and food
3. Do light to mendium exercise 30 mins a day (ideally in the morning whan your metabolism is high so you burn more calories)
4. Drink plenty of loose green tea (not Lipton). There is a good tea shop in Hyatt Plaza Mall (opp Comm Bank branch).

Good luck.
