I don't know. Are you 191 pounds now???

Pick a starting weight. Then pounds lost per week. Then present weight.

So,

March 1, 2016 - 206
Pounds lost this week: whatever it is
Present weight - 191 and whatever

So you need a weigh in day once a week, then you would have to change your signature. Most people I follow on YouTube weigh-in on Sunday night and report pounds lost and present weight on Monday. It is mainly for you because from week to week other people don't really care that much. People are more interested in general numbers...like how much did you lose in six months or a year. Just my opinion.

Good luck!
