Sunday night is my cheat night. I eat a huge kebab, popcorn chicken, sometimes halloumi cheese and then often follow up with various desserts and cakes. I know to not bother weighing myself for a couple of days as it's a pretty false reading. By Wednesday I'm usually back to where I was before the 'pig out'. A couple of times over Xmas and January I've had a few consecutive days of eating plenty in the evening. Again, give it a few days and it comes back to the norm.
Mind you, it's odd, I was at my lowest (15st 2.6) on Friday and had two really good days of low calories and good exercise (I'm even cycling in to work now. It's only 2 miles, but it all helps, right?) and I was excited to weigh in on Saturday and Sunday morning, expecting to push into new territory for weight... but came in at 15st 2.9 and then 15st 2.6 again... I was half tempted to have a good day on Sunday too, as I expect I would weight in down a couple more pounds at some point. Still, no rush. I'll wait until Wednesday again now.

I do have to keep reminding myself I can afford that extra biscuit now and then. I set 15st as my target this year as I started at 16st on Jan 1st... I'm almost already there!
Ha ha, yeah, those two days would annoy me too! How long is the streak now though? Maybe quote that instead? 10k steps is such a simple yet effective target, but I think so good for those that might not be very active generally.
