Trends:

The date under week is the Monday of each week, the weight is what I weighed at the end of that week, the calorie deficit is how many calories I was under my calorie allowance that week, and the weight loss is what I lost compared to the week before.  I'm hoping that looking at these figures in this relation will help me spot some kind of trend.
