Hi
@Titch68 . There is info about it here
https://www.diabetes.org.uk/about_u...iet-to-help-people-with-type-2-into-remission. There has been a bit of a postcode lottery, qregarding availability, and it does appear to be being used now as a cheap way to reduce the numbers of people with T2 diabetes complications.
Although some people have some success in losing weight and lowering their HbA1c levels, there has been criticism about the advice for after the severe calorie reduction stage. When people return to the standard NHS advice to eat starchy carbohydrates with every meal, they regain weight and start to see increase in blood glucose levels again.
As long as people have a reliable follow on diet plan after the very low calorie phase this can be a kick start to better weight and diabetes control. From my own perspective, I followed the Newcastle diet ( which this soup and shakes is an extension of) when it was still in experimental stage. Lost 49kg and saw non diabetes blood glucose levels for several years following. Unforunately, I was given a follow on plan as standard, and regained some 20kg, which don’t want to be lost again. This is despite me using intermittent fasting , low carb / keto way of eating for the past seven years. I have maintained non-diabetes , or pre-diabetes BG levels until about 2 years ago. I have had T2 for 18 years with no diabetes complications though.
I would advise anyone considering the soup and shake method to make sure they get support of HCP, family and friends, have a follow on plan for after the restrictive calorie phase, and for the latter I would recommend reducing the carbs in their diet.
