How can I stop notifying my friends of my live stream?

Every time I stream Twitch on Xbox, my friends keep getting constant notifications that I am streaming. This is true for all my friends, including those who have me "Favorited" and those who do not have me favorited. I do not want to appear offline, because I want them to know I am on and playing so they can join me, but I dont want them to get notifications every 30 seconds about my stream.
