You will lose weight that way but you will not lose the right type of weight. You will lose muscle and not fat. Try the following:
Burn more calories than you eat.
Cut your fat intake.
Eat three cups of fat free low cal yogurt a day (make sure it has live cultures in it) and pineapples. This helps you break down your food and promotes weight loss. You still need to eat low fat proteins. You will probably need 1600-2000 calories a day.
Do 45-60 min. of aerobic exercise a day (preferably before you eat in the morning). This will attack the fat. Try to supplement your training with some running, running stairs or hills, and cycling. Mix it up, it will keep your body guessing.
Do 30 min of weight training three times a week. This will build lean muscle which will in turn burn fat.
Keep moving all the time. Tap you feet while at the computer, tap you hands on your legs while walking. Keep moving and keep burning calories.
I LOST 40 LBS IN TWO MONTHS!!! (Is that fast enough?) I have kept it off for 18 more months doing this. I did not lose any strength and gained more energy. I also took my body fat % from 30% to 10% and my waist from 36 inches to 31 inches.
Consult a Doctor to see how much weight you really need to lose. Get some toning lotion to keep your skin firm so that you don't have lose skin that looks like fat when you lose the weight.

People, stop answering her questions, because she obviously is leaning towards Anorexia with these obsessive and unhealthy weight loss ideas. If she wants to be an idiot and hurt herself on her quest to "get thin quick" then let her do it herself and maybe she'll learn the hard way.

If you only eat that, and go to the gym everyday you will probably faint.
I would add a small about of low GI (a cup of brown rice or wholemeal pasta) a day. And you should eat some protein, even just some tinned fish.
As to how much you will lose, that depends on how much water you are holding already, fluid is all you will lose.
Your body would go into starvation mode and store everything you eat. So if you did break your diet (as you probably would) and ate something fatty your body would store it instead of burning it.
I know you didn't want to hear this, but it isn't a healthy way to lose weight. Tweek it a little, with some carbs and protein and it would be fine.

No, you don't even have 1 item with any protein in your diet. If you have weight to lose you can lose about 2 lbs of fat a week, it's a fact. Your temporary weight lose with soup was simply emptying you digestive tract and water lose. And it was temporary wasn't it? ( BTW I know the answer)

I know, I know not to say anything but you might want to add kelp, nori, or some form of sea vegetable. Not only will it help you with your diet, but eating sea vegetables helps tone down the craving for sugar (which adds many, many pounds/kgs), and is high in protein and calcium -- which from your diet, you're not getting enough of. Please check this link I'll post to you. It's all about kelp and sea vegetables and how they're an important part of your diet. Plus, they're super low in calories! )
