I'm 13, 5'8 and 170 pounds. I really want to be more confident in myself.
I think,you need keep to a diet and have more workouts. Lucky for you! I hope,you'll be fine
You gotta be prepared for a life change. You can't just lose the weight and go back to your normal life because guess what got you where you are...
I recommend small changes that you can stick to, adding up to big changes over time.
Start eating some more vegetables. Substitute healthier snacks. Do small workouts. Cut out some sugar in your day. Keep it simple enough that you don't feel too deprived. Small things you stick to become habits. As you start to get a little healthier you'll naturally seek out more challenge and more changes. Don't let setbacks feel like defeat. It's a long process and you will definitely have setbacks. They're a part of the process.
You can change your life if you want to, it just takes time and a little persistence.
It doesn't matter how much you exercise without proper nutrition. Remember not to become obsessed with the scale. Measure your loss on size drop. The weight drop will come after. Some people, especially women, can gain muscle growth as fast as they are burning the fat off. So the scale won't change right away. Check the scale once a week on the same day, same time. True weight is right after you wake.
