You aren't eating enough.

Naughty!
From what you have listed above, you have had about 650cals.
You need to be eating
at least 1,300 a day to lose weight, and should preferably eat about 1,800.
Any lower than 1,300 and your body will convert the food you are eating into fat.
The reason why you aren't losing weight when you are eating so little is that your body is convinced you are starving. So when you do eat, your body hoards the food it has been given and stores it as fat because it is expecting to be continually starved.
If the body is always getting nutritious food, and regular intervals then it has no need to hold onto anything it doesn't need. So it burns food and calories more effectively.
Losing weight is not about restricting what you eat. It about changing to eat healthy and sensibly. You need to et little and often to keep your blood sugar and metabolism high.
There are a few rules you should try to follow.
- Eat five or six times a day. Three small healthy meals with two-three snacks. This will keep your metabolism up and you will burn off fat faster.
- Try and workout 3-5 times a week for at least 30 minutes each.
- Cheat. Yep, that's right, cheat! Take one day a week to treat yourself for your hard work, just don’t go overboard
So, saying that here's an example menu for you, to show you what you should be eating.

3 shredded wheat – with half pint of semi-skim milk
Piece of fruit
Tea or Coffee –no sugar and skim milk only

So this week you tried it one way, and put weight on. Don't be disheartened, try the above and exercise 4x a week at medium intensity rather than 2x high intensity and try this way for a week and I am sure you will lose quite a bit of weight!
