I chose a weight that feels healthy and looks like I have a low amount of fat over my muscles. Honestly those weights dont matter if you strenght train because your muscle will make you weigh more. I chose the low end, whatever weight that makes me feel (not look) good in my clothes!

The BMI chart says my healthy weight range is 107-145 pounds. I am currently down to 135.5lbs, which is a healthy weight for my height, but it feels too heavy for me and I'm still pretty badly out of shape. I'm aiming for 126lbs as my target weight, as it is the weight I always felt most comfortable at in my teens and early twenties. You're in a healthy weight range now - I'd say just go to the point you feel comfortable with your weight (obviously so long as it's not below 125!)

I wonder whether this sort of ideal weight calculator would be better. It keeps in mind frame size too. Which for me comes out as 114-127lbs as a healthy weight, which does seem much more appropriate.

Personally I think bmis are bunk on an individual scale, but it's a good general population range. I'm 5'9" and 125lbs and am not even remotely unhealthy or even what anyone would call "thin". Bodytypes are different, just go with what feels healthy. But do remember that if you're striving to be firm/sleek instead of small and flabby, the number isn't going to matter

I look in the mirror. When I look the way I want, I stop trying to have a calorie deficit.

you should google "waist to hip circumference". This is a much healthier measure of health than BMI which doesn't take into consideration bone structure, muscle, etc. There are plenty of people walking around with healthy BMIs that are flabby. Many are discounting BMI as a 100% indicator of health.

Your ultimate goalweight has to be personal I think. I know as a shorter person I look dumpy towards the higher end of my BMI healthy range...so I am aiming for slightly lower. I'd imagine that a taller person might suit being slightly heavier and not running the risk of being 'gangly'!
I'm in the dumpy stage now so really hoping the last few kilos drop off asap!! :-)

I am 5'6" and my happy weight is around 123-125. That is where I feel great and my size 6 Levi's fit just right. I am trying to focus on gaining muscle now, so the number on the scale is less meaningful. I would be very happy to weigh more and look better.

@melodyis4reals - Congratulations on your 17lb loss! Keep up the great work!

I am 5'6" my goal weight is 128. I have heavy bones - built to pull a plow. and with 5 to go at 133 pounds I am pretty bony and good muscle definition. Waist is 26.5 and hips are 36.

So to add to what I wrote 6 weeks ago, I reached my initial goal weight of 125 and need to decide now what my next goal should be. I think it really is just a guessing game. At 148 I had no idea what 125 would look like on me. Now that I'm at 125 I see I still need to be a few more pounds down. I'm thinking I'll shoot for 118 with the understanding that I don't have to be set on that number. It's just a number and it's ultimately more about how I look and feel.

I agree, Mrs. Schimmy. BMI is nothing more than a "fancy" version of the old height-weight chart.

All my gym friends keep telling me it's all about the mirror...not the scale. I'm finding this to be true

I agree with a lot of the comments here. Small boned people should typically weigh less than a large boned people of the same height. My friend and I are the same height but even at the same weight we are very different clothing sizes because of our differing bone structure.

Some is weight distribution. Check your waist / hip ratio to make sure it's in a healthy range.

Also, how do you look? Do you look chunky or scrawny at a certain weight? Maybe that's an indication you should modify. But, know that in N America we have "fat eye". Many slim people are called skinny and scrawny and they are actually a healthy, beautiful ideal. (And, I say that as someone who would have to work HARD to look skinny if it was even possible.)

Ultimately I picked a weight that was 5 lbs bigger than I was when I was 20, is just a teeny bit below the middle of my healthy weight range and makes me feel good. I don't go by sizes but for reference I'm 5'8", my waist to hip ratio is 0.63 and I wear a size 4/6 (sometimes 0 or 2 in dresses because I have a small frame). That all makes me appear slender with curves which is a look I like.

So I guess what I'm saying is weight is one important component but there are so many others. Enjoy your journey!
