I am afraid low cal squashes or not an option on the diet due to the citric acid in most and also low cal isn't no cal. Check your pink and blue booklet on page 2/3 for exact guidance.
Ice poles are ok as long as they are just ice but if you mean the ones you buy for kids with flavouring in then again I am afraid no!!
Saying that it is raining really hard and horrible here so you could have a nice hot black coffee or even better a nice hot bath and just hang in there for ketosis to kick in which should be sooner rather than later now.
Thankkz fr replying so quickly ICE. Im not a tea/coffee lover, i mainly drink water as a rule, but i think its the amount im drinking now haha. I thought ketosis happened on 2nd day of diet, but im feeling really good. How much do u think i will lose in a week?? Im 17 stone at the minute.
