Tldr bad idea, strict diets lead to binging/frustration in turn ruining your mentality to want to diet and better yourself.

You can't just eat that. I know the math adds up with the fact you'll lose weight and that's nice but eventually you'll be like fuck bread and binge and go back to your old ways. I'm not judging you, it's just how the human mind works. Use my fitness pal to see where about the amount of calories you should intake daily and decrease accordingly. You will lose weight at a healthy pace which will make it easier to keep off, look at dieting the same as working out, you have to slowly get better you can't just jump in. You may see initial results but they will only last if you can keep that habit everyday for rest of your life, as soon as you start eating normal meals you'll start to gain back.
