Whilst this is a site, primarily for the support of diabetics and those associated with them, if you just try Dr Goole and put in a couple of those examples, I found that when I Googled "8-week blood sugar diet", and "intermittent fasting for weight loss", this site featured on the front page. My guess is if I had added forum or discussion to those, it might have been close to the top of the results returned.
As I understand it, the site welcomes anyone who can genuinely find support with a common problem.
These day, I must admit I am sometimes bewildered by the focus new members place on weight loss, rather than reducing worrying blood scores, but some of the messaging out there, both from professionals and the pres/tv is that weight is critical in many medical conditions and diabetes always features new to if not at the top of those lists.
