New to this lifestyle change

Hi, my name is Kelly. I'm 27 and I just started to eat better around the beginning of August. I'm not much into diet and exercise, never really have been. But I'm ready for a lifestyle change! Last time I was weighed I was at 215 lb. I'm not sure how much weight I've actually lost as I don't have a weight scale to measure and keep track of it, but I know I've lost weight due to the fact I am actually wearing smaller pants. I just downloaded this app today and because of that I actually did my first real exercises since I changed my eating habits. I'm hoping I can keep this going to get down to a more reasonable size for my height. I hope I'm actually able to keep going and keep this change in my life because I like the person I am becoming.
