Edit not to mention the 400 dollers a month cost for the first year!

This does include 24/7 doctor support and being the USA a lot of their clients save more than this on their "co-payments" for insulin etc. They are taking on the type of people we tell to talk to their GP before doing low carb, knowing they will not get the needed support from their GP.....
Mostly their services are being paid for by a few large employers who "self-insure" for their employee's health care, as far as I can tell, this is based on "payment by results" often saving more drug costs in the first year then the cost of the program. Even without the benefits of scale, the NHS could get, VirtaHealth's program costs less than Bariatric surgery, we need long-term results to know if VirtaHealth's program gives as good results.
Let's remember that some of the best information on "low carb" is in the books their directors wrote and we all benefit from, but they found that without active support most people could not make "low carb" a lifelong option.
Dr David Unwin (a UK GP) gets about 25% "diet control of Type2" at a much lower cost, but he gets to see people before they are at the stage of needing insulin. However, unlike Virta Health or the ND, Dr David Unwin patients have not made an informed choice, and therefore some of them are not committed. (And this is why the NHS will never be able to repeat the results we see on this forum......)
