BORIS Johnson has given up booze for the month to help him keep trim.
The PM, 56, has swapped pints and red wine for soft drinks and non-alcoholic beer to observe Dry January.
He has also gone on the 5:2 diet — eat what you want for five days, fast the other two — on the advice of partner Carrie Symonds.
He has lost two stone since last April when he nearly died from Covid — later admitting he was “way overweight” when he contracted the disease and went into intensive care.
A close source said: “Boris has always enjoyed a social drink but has been enduring, and succeeding so far, with Dry January.
“He’s had drinks like Heineken Blue and other low alcohol stuff to get him through.
“His health’s never been more important to him and he’s gone on the 5:2 diet with Carrie’s encouragement — although dieting can make him miserable.”
Mr Johnson has also been running, playing tennis and cycling to keep in shape.
Since recovering from Covid, he claims to be “fitter than several butcher’s dogs”.
