It could work, but I'd consider binning the weekend alcohol and "dirty saturday", as it could seriously hamper progress.
The porridge for Breakfast is okay, ut consider perhaps more protein, like Chicken, Turkey, Ham, ground Beef etc.
You can also include snacks between meals like Avocado, Carrot Sticks, Celery Sticks, Low Fat Cheese, Peanuts, Microwave Beans, Rice or Soup, Fruit, Sandwiches, Yoghurt Pots, Tofu, Boiled Eggs, Nuts and Seeds.
Those are all things you can use as snacks or to be part of snack options. Obviously you should be able to tell which of those represent whole snacks and which represent partial snacks.
