Hello there. I am a 13 year old boy. I weigh 40.7 kg, my height is about 140 cm and I need to lose weight. I would like to have a good body shape before I hit puberty. Most fat is located in my upper body. I do not work out.

My questions are:

what are the best methods to lose weight at my age?

What foods are best to burn calories?

How often should I work out?

What type of exercises should I be doing?

I would like a straight answer, from someone who knows what they're talking about. Thanks!
