I don't know the diet you are talking about but i have a fool proof diet that always works for everyone.
You make a plate of food that you would normally eat. It does not matter what it is.
Just your usual food. This way there is no new type of prep you need to learn.
Then you take another plate and move half of the food to the new plate.
Put the plate in the fridge for tomorrow.
Eat your food.
Guaranteed results with no complicated recipies or methods.!
