the chocs which r lying ard in ur house, give them to ur family
members or frens to eat. if u see it lying ard, u will feel like
eating it. & dun go to the supermarket to replenish ur stocks
of chocs hor. 
try choosing foods wif a lower fat content eg low-fat milk.
remove the skin on meats, no deep fried foods, try taking plain
water instead of bottled juices or soft drinks.
lastly dun let urself get too hungry bcos once u feel very hungry,
u will automatically aim for high-sugar foods like chocs & soft
drinks & oso u will tend to eat more at ur next meal. the
reason being ur body is low on glucose(energy) so u crave for
sugary foods to replace the glucose. if u can, try to have smaller
meals spread throughout the day.
