Sorry if I keep asking here

Okay.
I need opinions from you all ..
About exercise .
I always go walking on every evening (5days/week)
for 40minutes and 1 round of jogging
and at night , i do crunches and other exercises that related to stomach
is it okay for me?(for an obese

)
About meals .
Im a student ( secondary school)
in the morning , i eat a slice of wholemeal bread and a small cup of milo(boxed one)
and at school i eat 2 slices of banana bread .
as for lunch , i eat chicken soup with rice/meehoon (chicken breast) w/o skins .
tea time , i eat a slice of wholemeal bread and a small cup of orange juice.
dinner , i eat soup or cereals .
i dont know whether this foods can help me
