im 15 years old girl and wanna lose weight

I lost about 40 pounds in a few months, (200 pounds to 159) me and my mother started this diet and we stuck to it. I went to the gym everyday for atleast 30-40 minutes. I did the 5 pound dunbells, I still do them. im doing 2 reps of 50 with those, you know where you hold your arm straight out with the dunbell in your hand, and bring it up like your trying to fly. I also use the 10 pounds for the normal bicep curls.. its really hard losing weight after you lost a lot, you have to push your game harder. now im on the bike everyday for 33 minutes while using 3 pound dunbells.. a lot of exercise is usually the key to losing weight, even parking as far as you can from a mall or a store helps out. walking is one of the best things you can do. I love going on 30min-1 hour walks on a cool night, and it really does help too. I stay away from fast food, butter, bread and sugar. veggies and lean, no skinned boneless chicken is what I’ve been living on. make sure to fill up on veggies though, I love broccoli. a nice piece of fish is very good for you to as long as its not breaded. I hope I helped you out. losing weight is never easy but once you start losing it gets easier. good luck and I hope you reach your goal!
