Well, it is hard to know what to advise you about a healthy body plan without knowing what you're eating, how you're exercising, and what your overall focus is. I personally really don't find it helpful in my outlook of myself to go by weight - weight hardly means anything in terms of health and fitness (there are much better indicators of your overall health and body shape) and women can really go into a downward self esteem spiral if they focus too much on weight (as someone who has had an ED, please be careful of how you approach weight loss!).
The basic idea that many follow is to count your calories and make sure you burn off more during exercise than you eat during the day. But I can say that it is very helpful to mix up your exercise routine often to avoid plateaus, as well as mix up your diet. Don't totally cut out anything, because it will make you binge. Make sure to give yourself a day of relaxation every week and maybe just do some light stretching that day. Also understand that your body can really communicate a lot more than we often think it will. If you're geared toward health, you will discover that you innately know what foods are healthy by how you feel as you eat them or a few hours after you eat them - adjust your diet to what makes you feel you have the most strength and energy. The same goes for exercising - make sure to do activities that make your body feel on top of the world a few hours after (obviously sore and tired is good, but you'll notice which ones make your body really feel fantastic). I'd also look into meeting with a nutritionist or a trainer for a few sessions just to get a basic life plan for you to implement. A trainer can be expensive, but at the same time, you're investing in your health!
