Morning Susie,  hope you like JUDDD. 
 No I don't really do lc on purpose but I guess not eating much wheat helps keep the carbs low naturally.   I eat rice and potatoes too, but not huge amount.  I always have crisps on my UP day. Haven't had any wine since I started this.  Think I've on purpose kind of hypnotized myself into not liking it.  Watch out when I reach maintenance lol.  
Good that your having an UP day today so Saturday will be an UP day too.  I love Saturday UP days, but I'm doing strict rotation and yesterday was DD, anyhow I survived and 1lb more gone overnight so 7lbs from my goal.   Won't weigh in again until Sat morning after a DD on friday.    
It's the end of my JUDDD induction tomorrow, but keeping my numbers the same maybe a few more on a DD and a bit less on an UP day to even it out?  
M&S poppadums are only 35 calories each if you want a crunch and some of their soups are low too.  
Don't know about the skinny SIRT 1 gene thing, but I do know my appetite is suppressed and I definitely am much calmer and happier. 
Ask away any questions you have.  x
