This will get you off to a great start, but if you have a lot to lose and expect to be doing this for longer than a couple of months then I would recommend you work out your TDEE and minus 20%. It will give you a higher number of calories to eat, weight loss will be slightly slower but you will be less likely to fall off the wagon and more likely to give your body the nutrients it needs. It will also reduce the chance of hitting a plateau.
If you can, I also recommend ditching the processed food, full of nasties that your body doesn't want or need. I'm also completely converted to minimising my sugar in take, it's hard initially because it's addictive and it's in bloody everything, but by only allowing myself 6 grams of naturally occuring sugar per day I feel a million times better in myself.
Finally look at what percentage of carbs, fat and protein is making up your total calories. Women tend to do well on a low carb protein rich diet. Fat is not bad for you, your body uses it for lots of things.
Obviously this comes from my own experience and everyone is different. Ultimately you have to find what works for you and your body. But by doing lots of research and experimenting I have managed to keep going even when the scales have stopped moving.
Good luck xxx
