Why do children with a higher bmi start puberty earlier?

I read that obese children, or children with a higher bmi start puberty earlier, and children who are underweight or have a lower bmi start later. Why exactly is this?

Quick answer: additional fatty tissue can supply increased lipid levels, including cholesterol, which is the basis for sexual hormones synthesis. Moreover, fat tissue can itself synthesize some feminine hormone lookalikes that can trigger early puberty (this is also why obesity is a factor influencing male hormones).
