Hey there &
A goal weight is a tricky thing. The weight the scale says we are is only really part of the equation. Like you were saying, you were 175 and that seemed fine for you. Weight doesn't equal fat. You'll know what your body is comfortable with as you get down towards your own individual best body weight.
You sound like you've got a solid plan. Make small changes & stick with them.
I've been a Weight Watchers member for about 17 months now. I've lost 100 lbs within that time. Still more to go, but I'm very happy with my progress. It's hard work! But, it feels very worth it.
Hope to see you around the boards often!
