I have fairly small hips for my size, and that’s one of the first places I lose weight. Like Jenny, my pants are also falling off of me after three weeks (and I just started exercise yesterday), though I’m not measuring this time. From past experience the most I’ve ever lost in my hips inch wise was 2 ½ (and that was after 20 lbs.). It basically depends on where you gain/lose first. It’s true that I lose there first, but it’s also where I gain last so this may not apply to you at all. If you have more to lose in your hips you may be able to lose more in that amount of time than I did; then again if you have more to lose in that area you may lose inches there more slowly than I did. It really all depends on your body, there’s no way to predict. Wow, that was a lot of rambling; I hope it made a little sense
