It is a rather messy petition, to be honest.
This is the wording:
Professor Taylor has shown that Type 2 diabetes can be reversed using a low carbohydrate, low calorie diet. The NHS has announced it is rolling out a programme to give pre-diabetics lifestyle help. There is no mention of the blood sugar diet which pre-diabetics and diabetics should be following.
The programme will cost £7 million pounds to run. The dietary advice will be the same as that currently being followed. We have a diabetes epidemic so the old advice is not working.
Dr Maureen Baker, of the Royal College of GPs, welcomed the scheme but she warned "The long-term behaviour changes we need to see is hard to inspire". However, there are forums for the Blood Sugar Diet which offer the support and inspiration needed which will also ease the burden on GP surgeries.
Both Taylor's Newcastle Diet and Moseley's Bloodsugar Diets are mentioned, and the implication is that these are low carb. They are only low carb because they are restricted to 800 calories a day, but the ND style meal replacement shakes often have added sugars, and the Bloodsugar Diet is heavily influenced by the Mediterranean Diet - which can be as low carb as you like, but traditionally the Mediterranean Diet can also be heavy on the pasta and rice and bread, if you want, while Low Carbing is rarely calorie restricted, and even more rarely restricted to 800 calories a day.
The petition writer has provided no references to either diet, and seems to assume that low calorie means low carb - which it isn't necessarily. They also claim that Blood Sugar Diet forums are the solution. Except that of course wouldn't necessarily involve Low Carbing...
I would be first in line to sign a better written petition, but not this one.
Edited to add: Plus, if some HCP tried to push me into following some diet with just 800 calories a day, they would find I would push back pretty hard. I have served my time with highly reduced calorie diets, and I have promised my body to never do it again.
