He may want Scots to say Yes next year, but Alex Salmond has been learning how to say no of late:
no to puddings, no to biscuits and no to his big favourite: curries.
The result is that the First Minister has lost about two stones in recent weeks and he is pretty pleased about that progress, which he says is all due to the so-called 5:2 diet.
He says the diet, which restricts calories to 600 on two days every week, has worked well for him - and he may well be hoping that looking less heavy on television will play well with voters in the lead-up to the referendum.
But if Mr Salmond has been paying attention to his Government's own health campaigns, he will know the best way to lose weight, and keep it off, is by eating balanced meals rather than going on diet.
The problem with diets comes when you go back to eating normally. Rather like the economic forecasts on both sides of the independence debate, the figures can start creeping up.
