weight loss video diary?

Options
so I recently came up with this idea that i could do a sort of online video diary thing on youtube to help to motivate myself with my weight loss- i was wondering if there are other people who do a similar kind of thing or if there is some kind of weight loss of community on youtube? I've looked but i can't find that many channels that are uploading that kind of thing. It would be really helpful to be part of a community like that to keep myself accountable! so yeah.. any help would be appreciated :)
