Ok... this is what I do because it was from a chart I had (I put it all in Excel now - so it calculates it for me)
I measure my neck, biceps, forearms, wrists, bust (fullest) under bust, waist, hips, thighs, calves & ankles, as long as you do it in the same place each time - you get an idea of your inches lost. I could probably measure more places, but this is what was on the chart I used to have, so that's what I use.
Hope that helps
I wouldn't go crazy and measure weekly - like I said I haven't done it for a year, but monthly may be good. Sometimes the inches are a better indicator of your loss than the scale, especially if you are exercising and doing strength training as muscle weighs more than fat! I haven't lost many pounds lately, but the inches keep coming off - may I just say this one more time... wooohooooooooooooo
