u can try eating foods that help to burn fat such as citrus fruits like lemon and pineapple, apples, kiwi, bell peppers, cabbage.

Try not to eat white rice, eat brown rice(real brown rice taste nothing like white rice) brown rice is high in fiber whereas white rice is just starch.
u feel much fuller and u won't get hungry so fast.

i saw an article in the chinese newspaper on foods that contains slimming properties, but i don't know if it works but u can try...
celery:high in calcium which burns fat
outer layer of green lime:u hv 2 grate it into rin, there's something in it that can promote metabolism.
the inner layer of banana peel: scrape it with a spoon, it can decompose fat.( i ve tried this, but i can't really bear the taste so i gave up)
melon seeds:prevent fat from accumulating uo together, blend the seeds and gobble it down.

well, i don't like exercising at all, but there is a way to burn fat without working out, THat IS Gardeinng, it really uses up your energy, just 30mins of gardening and i feel so much lighter(spiritually too), we have a stretch of vegetable plot, u not only get to work out, u also get to reap the fruits of your garden.
i also advise u to do any kind of exercise in the morning b4 u eat, as it is at that time ur body has no food to burn on thus it will have to burn the fat.
wait for around 30-60 mins b4 u eat, consuming food will decrease the metabolism rate u ve work up.
