I'm shocked that they're saying Lchf is bad 4 your health
The diet that is WFPB is a high carb low fat diet and is based on whole grains. Our forum here is full of evidence both anecdotal and scientific that supports the view that an HCLF diet is not suitable for diabetics in general, I suggest you ask the WFPB website for evidence that supports their stance. So far most of their 'science' is based on the Adventist 2 study which has been shown to be a highly suspect and biassed study that was run by the 7th Day Adventists to 'prove' that their way of life is the most healthy. This may explain where the WFPB proponents gets their zeal from.
Followers of WFPB will make claims that their diet is a cure for T2D, but having tried it myself I can say that I found it took my bgl levels way too high and was actually dangerous for me. Others here have also experienced adverse effects from their diet, and so far to date there seems to be no one who has reported success using their diet plan. Check out the Success testimonials thread, because if it really worked for diabetics, then there should be at least 1 entry, but last time I scanned it there was zero. ZILCH!
There was a recent discussion in the forum of a comparison between diets being conducted by Harvard that also turned out to be heavily biassed in favour of this HF diet. but in fact the data they used supported the Low Carb diet, but the conclusion they incorrectly drew was the opposite. It was quite blatent, but got news coverage recently using just the summary section without any attempts to check if the study was reliable. EDIT to add: this is the report that was just linkd into this thread a few posts ago
This is not saying that a vegan diet is wrong or dangerous, it is merely this particular variant that we have problems with, along with their insistance that it will cure diabetes ( along with cancer, Parkinsons, dementia and 309 associated ills to quote their sales spiel and books). There are people who successfully follow a vegan diet and there is advice in the forum and its own thread. But WFPB is a different beastie.
