This is not meant to sound preachy or rude, but 3.75lbs a month. Considering you weigh around 115lbs, you probably were losing a little too much weight at a time. That kind of weight loss, would be more likely to be mostly Fat, if you'd been 200+ lbs overweight. Most people who weigh around 165, that may be a bit overweight, should aim for 2lbs a week, 8 a month.
You may have lost some muscle, water and maybe even some Bone density, with the Fat.
Good job on the weight loss, but just be aware of what I said, as your weight loss may have come with the aforementioned subtle health risks and you don't want lower water in the body incase you possibly promote higher risk of things like reduced cellular Oxygen, increased Dehydration risk, also Gout and Kidney Stones, because you can't flush KS's and Uric Acid out as easily. Plus reduced Bone density, (Osteopenia), T or Z score of betwen -2.5 and -1, could promote increased Fracture risk.
With this in mind, it would be advisable to maintain good Bone promoting foods, like Beans, Mushrooms, Rice, Pork, Liver, healthy Fat sources like Flax, Oils, Seeds, Soy, (Soybeans, Tofu, Tempeh, Edemame, Nattokinase), Nuts, Peanuts, Avocado, Fish, (remembering they contain heavy metals, so not too much or often), Omega 3 Eggs, (Chickens fed Flax), Low fat Cheese, Vitamin C foods, (C produces Collagen), Tomatos, Potatos, Broccoli, Pink Guava etc etc.
Such foods would help to potentially increase Bone density, as if you had Osteopenia, or were promoting it more though lack of Bone nutrition, anything like Cardiovascular exercise and / or weightlifting, could further promote increase risk of Bone cracks or fractures, when you eventually exerted some kind of stress on a bone or Joint, that had lost the ability to tolerate such things.
Good luck whatever you're deciding to do
