Hello, Rackellsie
First thing I would advise is that you make sure you do have some sort of medical advice/support. It took me a long time to persuade my GP that Newcastle diet was the method I wanted to use. I found support from GP, practice nurse, and more so from a local independent pharmacy.
The reason I say get support is that this is a drastic measure to take, and if you are monitored regularly you will avoid any problems of blood glucose going too low, also ketone levels being too high.
You don't mention how you are going about Newcastle diet. Which products you use and what else you are consuming. Some meal replacement products are quite high in carbs, which don't help some people despite the calorie restriction.
I recommend that you get a copy of the Newcastle diet research details and take them to your GP or nurse.
Congratulations on your decision, it is not something to take without consideration, also you need determination to stick to the 8 weeks. Some forum users have criticised Newcastle diet, but those who have done it are seeing good results. I did it 3 years ago, and have not had diabetes blood glucose since. There is good advice and support on the thread 'Newcastle diet advice'.
I would emphasise again, get a print out of the Newcastle diet information, Professor Taylor et al, take a copy to GP and nurse, and if possible to a supportive pharmacy. The products I used were only available from the pharmacy, (lipotrim), and only with GP approval. The cost included weekly monitoring by phamacy and I was also checked every 2 weeks at GP surgery.
Best of luck
