Actually, that was demonstrated in a well-controlled RCT that convincingly causally determined efficacy And as I said, it was about perspective. Different diets work better for different people!

DiRECT had cherry picked participants and got what 48% "reversal".. Virta is real world with no selection criteria and got 60% same criteria. Virta never claimed to be an RCT .. you could say the control group was the 88% of the US pop with disorded metabolisms?

Hm? They both had very similar selection criteria for participants. The main difference was that DiRECT was more rigorous and had better control, making it more likely to reflect an actual difference rather than simply the biases of the study authors

Virta ran a trial, for whatever reason, that would almost certainly inflate the true result, which is why most experts I know aren't particularly impressed with the study. DiRECT, conversely, ran an impressively well-controlled real-world RCT that is much more reliable

That's one reason why many governments are implementing DiRECT but no one's interested in Virta. It's also far more expensive

No-one interested in ViRTA apart of course from the people it is helping.. You know those coming off insulin reducing meds, HbA1c and weight.. no-one at all...

Indeed. Anecdotes abound, but governments don't fund based on word of mouth (mostly), they fund based on science. And currently, Virta hasn't demonstrated causality in the way that DiRECT has

No they don't where's the science behind the Eatwell Guide please? Ancel Keys? In which case it should have been rejected half a century ago? DiRECT hasn't proven the causality of T2 its has shown it can be reversed as has ViRTA using very similar criteria..

Eh, I said mostly, I'm not going to litigate every decision any government has made. DiRECT has proven causal efficacy far more robustly than Virta, that's the whole point

More robustly possibly but less successfully so which is worth more to patients?

Ah but that's the issue. Hard to tell if the ~60% estimate from Virta's study is meaningful because of the biases, whereas the point estimate from DiRECT of ~45% is very robust
