More than a fifth of people always miss breakfast and more than half sometimes skip lunch, according to a recent survey of 3,000 UK adults.
So what makes this a bad thing?
State registered dietitian Helen Bond warns, 'Skipping meals makes it more difficult to ensure your body is getting an adequate level of nutrients. People who don't eat breakfast may find they over-compensate mid-morning when hunger pangs take hold and nutritionally poor, quick-fix snack choices may be made that are high in fat and sugar, but low in vitamins and minerals.'
So if you're a meal skipper, you could be suffering nutritionally, with uneven blood sugar levels and energy troughs.

Helen, who is a member of the British Dietetic Association, adds, 'Water soluble vitamins like B and C are not stored in the body so get depleted very quickly - and so people who are not managing to eat a balanced diet or fall into irregular patterns of eating should try to eat healthier or consider taking a food supplement to help keep their vitamin levels at a normal level.'
Low-cal snack ideas
Predictably, snacks tend to fill the hunger gap for meal skippers - but watch what you grab to satisfy your hunger pangs.
'When blood sugar levels drop, you are more likely to reach for high fat, high sugar and high salt products which give a quick fix,' says Helen.
She recommends, instead, foods rich in B vitamins which help release energy more slowly thus helping prevent the mid-morning or mid-afternoon slump. Look out for cereals, dairy products, eggs meat, fish, green leafy vegetables and fresh fruit for vitamins, minerals and fibre.
