Hi Sarah, i really dont think it will affect her diet or weight loss at all.Some peeps like their shakes/soups thick and some find it easier if they add more water or some peeps split their packs in 2.
I am not an experieinced vlcd peep but i am sure someone will soon pop in and offer some more advice.
Take care xx
We had a locum counsellor a few weeks ago and she suggested to make a 'big' soup if you feel you need it by adding a savoury drink mix to a soup mix too. I do it sometimes and it really gives you the feeling of having had a proper portion of soup and tastes not much different to be honest. When I do this I use 350 ml water, 1 soup pack and 1 savoury drink. Remember you are only allowed 2 savoury drinks in a day though.
and I definately don't think using more water will make any difference at all
I asked my counsellor this when I first started the diet. I split my pack in two as I thought I wouldn't be able to cope on one pack for the evening. He said it's ok. Now I have my soup with 300mls and I find it lasts longer.
