Never, ever go shopping on an empty stomach!

Everything in that supermarket is designed to tempt you, from the aroma of freshly-made bread from the bakery, to the glistening fish laid out on ice, to the juicy-looking chickens on the rotisserie.

If you’re hungry you’re more likely to fill your trolley up with stuff that you didn’t really intend buying.

Go shopping after you’ve eaten and you’re less likely to give into temptation
