How do I go FB Live and captivate my audience?

I’m overweight and made a FB group to motivate others, I plan to go live to introduce myself and motivate others to join the group and support each other. What are good angles and speaking discussions or do I just turn it on and welcome people as they’re tuning in!!

Uplifting, inspiring, polite, supportive
