Are my diet menus will help me lose weight?

Hi! So, Im 16, 159.5cm and currently weight 49.4kg(after going on a diet routine where I ate less than 1000kcal a day). Before this my weight is 51kg something.. For 2 days, I cheated and left the diet routine because I had a massive food craving (after 2 weeks dieting), plus my family and I went to the cinemas. I ate a box of caramalized popcorn and 2 cups of sweet corn at 12 am until the movie ends. The next day, I ate cakes and a bowl of curry noodles. Im so so so dissapointed in myself now. So, now Im changing my diet routine as follows:-

Breakfast: 500ml of water

1 cup of green tea

1 piece of wholemeal bread with 1 teaspoon of Nutella spread

1 boiled egg

A half of cucumber

3 dates

Breaking Fast: 500ml of water

1 cup of green tea

A half of cucumber

1 sweet potato (boiled)

3 dates

I counted the calories and it is about 600++kcal, but less than 700kcal.. My aim is to eat less than 1000kcal.. Im planning to lose another 4kg and maintain that weight. Help me please.. Thank u...
