You clearly don't read the same threads as me then.
Every single T2 newbie thread that I read has Daisy1's contribution (no pushing LCHF there), and several people promoting self testing, to
tailor make a diet that works for them. There are usually comments from others who offer alternate views.
In addition, the DCUK website, and a pinned intro thread, strongly promote the Low Carb programme, which is very careful to introduce carb reduction systematically and sensibly over 10 weeks, of structured education. Again, carb control and real food are emphasised, not gobs of HF.
However, if you feel so strongly, why not post systematically on the newbie threads yourself? People like
@bluetit , myself,
@liam1955 and many others have been doing so for years, trying to offer newbies a non-pressured welcome where they can find their feet and find what works for
them.
