Not such a good week on weight loss journey

Starting weight (25 May 2018 = 273lb)
Today’s weight = 191.4 lb
Average weight last week = 190.7lb
Average weight this week = 190.2b
Weight loss this week = 0.5lb
Note: I weigh every day first thing and calculate weight loss based on average weight for the week.

Horrible week for me with URT infection since Tuesday evening which has greatly curtailed activity but not food input. Things were going so well and had hoped to record a substantial weight loss this week but have only managed a loss of 0.5lb when I compare this weeks average weight to last weeks. What makes it worse is that the trend for the week is up rather than down
