Don't go by weighing yourself daily - your weight fluctuates up to three pounds each day (taking let's say when you first get up, dressed the same way) - I KNOW that because I'm a daily weigher... I will fluctuate between 127 and 130 - one DAY it will be 128, the next day 130, then 130 again, then 127.5 the very NEXT day. That's just how it is. "Unexplained" weight loss is WITHOUT dieting, eating the SAME, and losing 10% of your body weight in 6 months.
You started low carbs, you started a hormone. So your weight loss is EXPLAINED and with what you have been doing (the low carbs and hormones) you SHOULD be losing weight!
