Weird loosing lots of inches but not much weight

Hi
i am a bit puzzled by my weight loss, now !About three years ago i stopped having contraceptive injection Depo provera as i was putting on a lot of weight and i reached just under 22 stone (i am 5ft 10 in)I did not diet or exercise as i found it difficult to diet ,However to my delight my weight started going down without doing any diet or exercise and last year i reached 19 13 LBs,Which was very good considering i did weigh 22 stone and was not dieting or execising,so it did seem a very good move comeing off depo provera as it is known for causing a lot of weight gain ,Now i am really puzzled !over the last year i was delighted to feel that my weight was still comeing off and my clothes were getting a lot looser on me and i found a jacket i could not put on last month i am now able to get into and work colleagues and family say i look a lot thinner!I dident weigh myself for a long time .However i did decide to weigh myself last week thinking going by the looseness of my clothes i would have lost quite a bit of weight, and that comeing of Depo provera had improved my metabolism Imagine my dissapointment when i got on scales i found i weighted 19stone 12lbs.Only one pound less than my lowest recorded weight nearly a year ago but going by my clothes i felt like i had lost a lot more.I felt my skirt getting even looser and i though oh well perhaps some more come off,but that is clearly not the case as scales only show a 1 lb loss ! though i am clearly a lot thinner than i was last year as my clothes getting very much more loooser and everyone tells me they can see i am a lot thiner both in my body and face.but scales not reflecting this weight change! very strange,I know i am very lucky to loose inches especially given the fact i am not dieting or exercising but really puzzled i am so much thinner but scales only now showing a 1 lb loss!I know you can loose inches and not weight when you exercise a lot and build muscle as muscle tissue a lot heavier,But i dont exercise and have not built muscle,i hate execise! even though i know i should! wondered if anyone else had experienced this strange phenonmen? or had any ideas as to why this is happening that i am loosing all this weight in inches but scales not reflecting this? It is not my imagination either or dodgy scales as i used the same reliable pay as you go scale that are in the same chemist shop and the same ones i weighed myslf on last year and the nurse at a leg clinic i go too also said i looked thinner and noticed my leg size for support hoisery had gone down to a lower size as wellAlso other ordinary scales tell me i am the same weight, as last year as wellOver the last month i have noticed a huge difference and that over last month i can get into skirts and clothes i previously could not get very comfortably in and work colleagues say i look like i lost some more weight this month even though my weight nearly the same as last year just about 1 lb different!i find it very weird
