If it was me I would go down the slimfast route.
Water on waking in the morning
Tea with a tiny splash of skimmed milk and sweeteners if you want
Slimfast for breakfast
More tea (it counts as your water intake)
More water
Lunch Slimfast again
more water and tea during the afternoon. Nothing else.
then for the evening meal
Steamed fish or grilled fish, I like kippers, smoked haddock, hake and cod.
Never fry it or even show it a frying pan lol.
Have with that some steamed veg, cauli, cabbage, carrots, runner beans etc. Eat it dry if you can, dont be tempted to put anything on it at all because even low fat/low sugar versions of sauces still have carbs and other things that you dont want in your system at the mo.
Remember that it doesn't matter if you dont enjoy your meals at the moment, because you are on a mission.
Consider it a job that has to be done.
Drink loads of water, I drink flavoured still water from Lidl. It is lovely stuff and not expensive.
The milk diet is a good option too but slimfast and a meal is great if you want to have the satisfaction of having eaten something.
Good luck.
