it sounds like you are ready to make a change which is good. i do not recommend dieting at this age as you are still growing and research shows dieting (especially at younger ages) is associated with weight gain over the long run. instead of losing weight i highly recommend focusing on creating a healthy lifestyle that is sustainable. speak with your parents about having everyone in the family eat well and exercise. have regular meals with plenty of fruits vegetables lean meats low fat dairy whole grains and healthy fats. a low carb diet means your diet will be deficient in key nutrients you need to grow and that includes calcium and vitamin d for bone growth. a recent study showed that young adults who ate intuitively focusing on hunger and fullness cues weighed less than those who had more controlled eating styles. so eat regular meals at the table stop when comfortably full and create healthy habits. you may not lose weight fast but the healthy habits will lead to weight that's right for your body type. seeing a pediatric dietitian can also help as they know what nutrients you need during this last stage of growth. to find a dietitian near you go to eatright. org. for more on teen nutrition see this webmd article.
