I always weigh on a Friday "officially", as in its the only weight I write down. That hasn't stopped me from weighing throughout the week and staring in shock at 4lbs that stuck to me stubbornly everyday.
I did a bit of research into water retention yesterday and drank just green tea and water all day to help "flush out" my system! And amazingly, I've only gained 2lb today instead of the 4 that was there yesterday.
This made me think it WAS half water retention (as I was sure I didn't overeat by 14,000 calories) and I am now going to be much more aware of much salt I have in my food. Not usually an issue, but when Christmas came around so did lots of cheese, crisps and white bread - all salty, all things not usually in my diet.
Anyway, feeling very positive! Will aim to get rid of that by next week and be off to a good start for the new year!
