Inches are a far better measure than your scale. Congrats you are doing great. A 2 kilo weight should be fine to start.

ppl wanna lose weight to look better don't they? To look slim, fit, toned, sexy. usually we use weight just as a mental representation for size, when in actuality, inches is, of course, a more accurate measurement of size. losing inches is the whole goal!  You're doing great!

Don't worry about that muscle weight. As a woman, normally you would have to be doing crazy diet and supplements and workouts to get "TOO" muscley. You're gonna be beautiful just keep doing what yer doing.

Thanx lena....i m using 1 kg dumbles for toning my arms.....is it safe?????

You are doing really great! If you lose inches, that means you are burning fat. If you don't lose weight, it is because you are building muscle. That pace is just right, as you are mainly reducing your body fat without any other significant change (well, you probably look better ). Keep going until you are lean (relatively low body fat). You might already have lost enough weight by then.

I don't see how this is a problem. As long as you can see physical results, that is, losing the inches then why do you need validation from a scale? :/ 

Took the words right out of my mouth! Right on!

Thanks Eric..I have started exercise as well...lets see what will be the results....

The reason you're losing inches and not weight is because you're gaining muscle density through your walks. Don't worry. It's completely normal, and a good thing! While you're losing fat you're gaining muscles at the same time, so it appears like you're not making any progress. But those muscles burn fat even faster. To drop numbers on the scale a little faster you'll need to add a couple exercises to your walking plan. Just 5 minutes a day to focus on building muscles in any areas where you feel some extra weight can come off, and those muscles will do all the work for you. But don't feel discouraged! The inches is where it really counts!
