I have done the cabbage soup diet and it really does work well, do you hate all cabbage? I use white cabbage so it is not that nasty strong flavoured green stuff!
Otherwise just do the diet without the soup.
Day 1 - Fresh fruit, eat as much fresh fruit as you like (except bananas) I do an exotic friut salad with pineapple, melon, grapes, passion fruit as a topping. Apples, satsumas, grapes, pears etc. Drink herbal tea (or black tea) and water. Avoid coffee, fizzy diet drinks etc.
Day 2 - Fresh veggies, eat everything in sight! I usually do a massive box of veggie sticks inc mini sweetcorn, sugar snap peas, peppers, carrots, cucumber, celery, tomatoes etc. Munch all day on these. In the evening you can have a large JKT potato with butter!! I do a veggie casserole with veggies and passata and herbs with it. Drink loads of water
Day 3 - Fresh friut and Veg, combine day one and two, but no jkt potato I usually have fruit salad for breakfast, veggie sticks during the day and fruit, then the remains of the veggie casserole for dinner.
I find this works really well, you can eat as much as you want (and I do eat loads) but I usually lose about 3 - 4lbs and my tummy feels much flatter afterwards.
