@BIWI you are kind.
Basically, left to my own hermit-like devices, I can eat BC-friendly food quite happily - eggs, homemade soups, salads, meat etc. I did dry January with hardly a wobble. I hit my 2l of water at least 6 days out of 7. My portion sizes are sensible.
Then life happens. On Wednesday I went out with a friend who has recently suffered a shocking bereavement so we drank too much while I listened and comforted. I didn't eat that badly - tapas stuff so easy to pick out the right foods.
Thursday night dinner with friend celebrating amazing, life changing news. Again I ate good choices for starters and mains but he was in a "let's push the boat out and have dessert" mood which I chose to go along with.
Friday, all day meeting at an offsite venue which I thought would have good lunch options but ended up being white bread sandwiches, crisps and cake! So I ate enough to stave off hunger.
One pint on Saturday which I've already fessed up to.
Et voilà , 4lb back on the scales today.
But there's not much choice other than to keep going, stick to the rules and hope that the losses will outweigh the gains.
