Foods equivalent for the Newcastle Diet?

I have read that the Newcastle Diet (ND) can reverse diabetes after 8 weeks of a low-carb and low-calorie diet based on liquid meal-replacement shakes and green vegetables. The shakes used were OptiFast and the shake part of the Cambridge Diet.

Tesco and ASDA in UK sell meal replacements UltraSlim and Great Shape respectively. These have essentially the same specification as OptiFast and Cambridge diet:

Product KCAL Fat Carb(Sugar) Fibre Protein £/meal
OptiFast 160 3.5g 18(4)g 3g 16g 3.00
Cambridge 200 2.6g 27(18)g 2.g 15.8g 2.30
UltraSlim 201 3.1g 26(18)g 2.8g 16.5g 0.40-0.50
Great Shape 201 3.4g 23(18)g 4.5g 17g 0.50-0.60

and also contain Vitamins and Minerals, but less than typical over-the-counter supplements.

Tuna sandwich on wholemeal slice and 50g tuna + multivitamin tablet:
Item KCAL Fat Carb(Sugar) Fibre Protein £/item
Slice 90 0.7g 15.1(1.6)g 2.7g 4g 0.05
Tuna 60 0.4g 0(0) - 13g 0.60
Vittabl. 0.05
-----------------------------------------------------------------
150 1.1 15 2.7 17g 0.70

Q1. Are the four meal-replacement shakes equivalent for the Newcastle Diet? If not, why?

Q2. The nutrient content shown by Tesco/ASDA for the tuna sandwich is about the same as the shakes above. Then is the sandwich equivalent to the shakes for the Newcastle diet? If not, why?

@Mark: I totally agree with you, i.e. the content spec of a meal should be near:

MEAL REPLACEMENT (for 3 meals - breakfast, lunch, dinner)
200 kcal for energy,
25-35g for carbohydrates,
2-3g for fibre,
17g for protein

GREEN VEGETABLES 200kcal/day

for all of them (to exclude unsuitable combinations) as specified for the Newcastle Diet.
That is good news because I would not be able put up with liquid shakes three times per day. Solid food and perhaps a very infrequent shake would be a lot better.
