remember to eat more fruits. To increase ur vitamins and mineral intake.
U need more carbohydrate too.
Say no no to hotdog. It is heavy in artificial stuff - u know what i mean. Replace it with other protein - white meat, eg: egg, fish and chicken.

For your breakfast - I think you're consuming too much sugar. And can you elaborate what you mean by "walking around a lot"?

1. Chocolate cream bread - the cream is fattening and full with sugar. Replace this with white bread or oats+milo or boiled eggs+milo. If you can, take your milo plain.
2. Oat biscuits - instead of taking this, why not take oats instead? Oats biscuits are nothing more than commercial cookies/ biscuits where they add a couple of oats and market it as "oats biscuit". It's excessively sweet, unhealthy (processed) and oily. Avoid biscuits/ cookies if you're planning to lose fat.

It seems that you're consuming sugar and fats (with the same food for dinner as breakfast) double in a day. Doesn't seem so good, does it?

Lunch
1. Hot dog? Aiyo~ any idea how hot dog is made? they blend meat, fats and some other parts (possibly internal organs - which is edible of course) together and insert them in a 'skin'. Yes they taste good but absolutely bad for health, especially since it's processed meat.
2. Recommendation - instead of eating hot dog, take steam or oven-baked chicken. Or, just tofu + vege & rice if you're okay with it. Throw in an apple if it's still not enough.

Bottom line, you're not eating enough yet each choice of your food are high in calories. In fact just eating few biscuits and 1 bread each for breakfast and dinner, you're somewhat "starving" your body from vege, fruits and protein - all the other nutrients necessary for a balanced body. Trust me when I say your current diet is bound to fail and instead of losing weight, you might even put on some weight.

What I think/ recommend:
Breakfast- milk + eggs/ milk + oats/ cornflakes + milk or eggs / bread+eggs etc (you get the idea, do whatever combo you want) if bread + jam is too plain, you can always toast your bread to make it tastier

Tea break - a piece of bread/ an apple/ a banana

Lunch - brown rice or white rice/ noodles, vege, meat/chicken/tofu/ egg (protein)

Tea break - a piece of bread/ an apple/ a banana or simple a cup of oats. Sometimes I take a small cup of cornflakes + plain milo

Dinner - brown rice or white rice, vege, meat/chicken/tofu/ egg (protein)

Supper - (if you must) 1-2 slice of fruits

And that should do nicely. Reason? You've got carbs, protein, fiber and even sugar all covered in a balanced manner. This is just an idea for you to kick start, feel free to improvise or replace some of the items as it suits you. Have fun and throw in chapatti & tandoori chicken at times. Pizza? Why not! But just 1 slice  Anyway different people have different eating habits. On days I plan to go to the gym, I actually have 2 tea breaks in the evening. One would be around 3+ to 4pm and another time at around 7pm - before I hit the gym. It's because I need energy to keep me going when I workout.

Also, on days I want KFC - I go for it. Just that I limit the number of times I eat it (eg. only once a month) and watch what I eat - chicken breast with no skin. Yet i'll make sure that I can only cheat if I'm going to the gym that day. Suppressing your appetite is not going to help in long run. I've tried that and it bounces each time. So eat what you want but plan ahead.
