Hey!
Right now you have a normal Body-Mass Index. And if you weighed 125, you would also have a normal BMI. So that does make it harder to lose those ten pounds.
You would need to increase your activity level beyond what you are used to doing now, and you'd have to stay pretty strictly on whatever food plan you follow. Plus, it would take awhile.
I'm wondering why it is you want to go from 135 to 125? If you were never able to lose even 1 more pound, would that make you miserable? Why? I'm not saying it should or shouldn't, just that it might be useful for you to think about it. It could be you are putting yourself in a position where you'll always be unhappy, when you don't need to do that.
I think that sometimes people think that losing weight is going to solve more problems than it actually does. They think "Now my life will work," or they think they will look like a younger person, or like someone who has never been overweight. Then when they reach goal, they feel disappointed because there are still issues in life, or because they don't look like they expected. So, they set another goal. But there's no reason why being even smaller will make things any better... do you see what I mean?
I'm not saying you shouldn't do it--you would still be a normal weight, not too thin--but just suggesting that you might want to be really clear about expectations.
Good luck!
Jay
