I've been saying it for years
Remember how I gave up booze for Lent (more than once) and lost one solitary pound in the whole 7 weeks?
My ex-FIL was a biochemist and laughed the first time I went on a diet and gave up drink - he said categorically there are no countable calories in wine.
And in Rosemary Conley's original books she recommended 2 glasses of wine per night; in her own trials with hundreds of men and women, with all the same rules except some drinking the 2 glasses of wine and the others not, the ones drinking lost more weight.
It does not, obviously, mean there are no fat drinkers, or no thin non-drinkers - and it's only wine and spirits that are non-fattening
The article also doesn't go into the overall health impact, it's only talking about weight.
