Will this diet work?!

Will this diet work?

I'm a 5'4 vegan an I weight between 9 and 10 stone. I've decide to try an lose a little weight. To do so i've decide to eat 4 meals a day, each under 200 calories, under 5g of fat an each space 4 hours apart.
Will this diet work for me??
(If not could you please give advice on one that could)

It should, also here is a recipe you can make:

INGREDIENTS
5 medium potatoes, peeled and cubed
2 carrots, chopped
1 stalk celery, chopped
4 1/2 cups water
4 cubes vegetable bouillon
1 tablespoon olive oil
1 large onion, diced
4 cloves garlic, minced
1 tablespoon chili powder
1 tablespoon cumin
1 1/2 tablespoons seasoned salt
1 (29 ounce) can hominy, drained
1 (28 ounce) can diced tomatoes with green chile peppers
salt and pepper to taste
DIRECTIONS
Place the potatoes, carrots, and celery in a pot with enough lightly salted water to cover, and bring to a boil. Cook about 10 minutes, until slightly tender. Drain, and set aside.
Place the 4 1/2 cups water and vegetable bouillon cubes in a pot. Bring to a boil, and cook until bouillon cubes have dissolved. Remove from heat, and set aside.
Heat the olive oil in a large pot. Saute the onion and garlic until tender. Season with chili powder, cumin, and seasoned salt. Mix in the potatoes, carrots, and celery. Cook and stir about 2 minutes, until heated through. Mix in the water and dissolved bouillon cube mixture, hominy, and diced tomatoes with green chiles. Bring to a boil, reduce heat, and simmer 45 minutes. Season with salt and pepper to taste.
