How do you help an already active child lose weight?

I found the most effective way to lose weight is HIIT training. For a youth it can be modified, however in principle, a full workout can be done in little as 12-16 minutes.

A nice field with 6-9 sprints (100 m) will be effective as the body will lose weight throughout the day. the fewer breaks between sprints (around 90 seconds) is what makes this effective. also helps build bone density improve circulation and cardiovascular function.

It is cheap, quick, and you will see amazing results within 2 weeks.

This seriously helped me lose over 30 pounds in 3 months and i have amazing energy now and improved skin.
