Holford Diet site’s interesting take on Cochrane Review

Holford has had varied engagements with Cochrane Reviews, so we were interested to see the Holford Diet site – which promotes a low glycaemic load (LGL) diet plus supplements – celebrating one Review’s alleged finding that

a low GL diet is more effective than any other diet for weight loss and improving overall health…’Overweight or obese people lost more weight on a low Glycemic Load diet and had more improvements in lipid profiles than those receiving conventional diets.’

However, on looking at the Review itself we noted that it did not distinguish between LGL and low glycaemic index (LGI) diets. This was a review of

Randomised controlled trials comparing a low glycaemic index or load diet (LGI) with a higher glycaemic index or load diet or other diet (Cdiet) in overweight or obese people.

The review found some evidence that LGI and LGL diets can be especially beneficial, but did not aim to find whether an LGI or LGL diet was best. Given that this was a review of only six trials involving only 202 participants, this seems a sensible decision.

While it is nice to see a Holford site referring to such good quality sources, it is a shame that the Review could not have been reported more accurately.
