Hi

So I would like to stop losing. I feel comfortable at this weight. How can I stop or slow down the process?

I wouldn't try to bring it to a halt unless you are at a point where you are so underweight that your health is suffering. Anything you lose has a chance of coming back, and the longer you lose, the greater the odds of the last few pounds returning. So I'd say you take what you can get in the way of weight loss, and if you are happy where you are, your body will likely help you settle back there once maintenance begins. However, it wants to be heavier than you want, so once you are back there, you will have to be more proactive about shutting down the rebound.
