Interesting but
- study was small. Only 316 participants
- results only mention HbA1C as a indicator of success. No mention of Time in Range or general quality of life - mental health is as important as HbA1C.
- dubious time following VLCD: 2.2 +/- 3.9 years ... so some people have been following VLCD for negative 1.7 years
- results based on a self selecting survey made to prove the value of VLCD. You would not be a member of Type1Grit if you were not successfully following VLCD. Those who struggled with the diet would not be a member of the group to complete the survey.
- comparison with average T1 rather than those who successfully maintain similar “exceptional glycaemic control” with less restrictions on diet. Yes, it is possible.
