34 diet and fitness tips you need to know

21. Don't go exercise crazy
'Being a fitness junkie is probably more dangerous than not doing anything at all and even I don't exercise every day. But I am good more often than not. It's the 80/20 thing - if you're good for 80 per cent of the time, you can be bad for the other 20 per cent.'
Aerobics instructor and actress Beverley Callard, who plays Liz McDonald in Coronation Street. She's just released her fourth fitness video Lasting Results, (£9.99 VHS, £13.24 DVD)

23. The great outdoors
'Central heating, open fires, poor ventilation and stress all cause havoc with our bodies. They can cause us to be listless, droopy-eyed and tired - not to mention what they do to our appearance. So combat this by getting out and about as much as possible. Try to fit in a walk, even just ten minutes, every day. It will be ten minutes well spent and will make you feel great and help you sleep better too.'

24. Be clever on holiday
'Don't crash diet before you go away on holiday, you'll be so hungry when you get to your destination you'll eat everything and anything. It's better to eat sensibly before and during your stay.'

25. Go nuts
'Pistachios are a good source of potassium and they provide a whole collection of heart friendly nutrients such as vitamin B6, magnesium and copper and are a useful source of antioxidants, including selenium and vitamin E. They are also cholesterol free and snacking on them regularly, within a healthy, balanced diet, may actually help to reduce blood cholesterol levels.'
