Weight loss...many pounds did you lose before you started to notice?

I do not own a scale...but I am intermittent fasting and on phentermine, not exercising right now because my RA is flared terribly bad.

But....my pants are fitting better. I think the majority on my weight was in my legs, hips and lower abdomen. And in the mirror I see a difference.

How many lbs did you lose before you noticed? *this is simply out of curiosity**
