it's a complicated answer...
yes, no and maybe all at the same time..
you are allowed to "flexi syn" as it's called but what the definition of that is differs from consultant to consultant..
ours says you have 105 for the week and can use them how you see fit, others say you have 15 a day but can have more on one day and less on the next / previous as needed, but not an entire weeks worth in one day..
think about it though..
if you have none all week then 105 on the last day before weigh in, you're undoing all of that weeks work in one go..
105 syns is 2100 calories which is over what a woman should have per day, and that's before any proper food..
they are there for ballance and so you don't feel deprived though so it's up to you how you use them..
I just googled for calorie recomendations and found this site..
usefull to know how many calories you need to maintain your current weight ( you need around 600 less than this to lose weight.. )
