THE average person in Yorkshire will now want to lose 5lbs in weight after Christmas and New Year gorging.

A healthy diet and a new fitness regime once again tops the bill of New Year's resolutions in the county.

But a health and fitness chain claims it is a myth that the weight is caused by Christmas Day and Boxing Day - as people generally over-indulge throughout December.

David Lloyd Leisure reckons the amount of weight that needs to be lost in Yorkshire adds up to 20m lbs.

It says the average 5lbs weight gain - just over one-third of a stone or 2.3kg - is due to an intake of an extra 250 calories a day over the Christmas period combined with a general slump in activity.

Nutritionist, Fiona Hunter says December's menu of fatty foods and lazy, booze-filled days provides a fast track recipe to weight gain.

She said: "Everyone always blames the Christmas dinner for our January excess, but the traditional turkey and the trimmings are not the real problem.

"For many people the festive eating and drink starts in early December and lasts until the beginning of January.

"The weight gain is more likely to be the result of four weeks of eating and drinking more than usual combined with a dramatic drop in exercise."

Trainer Peter Hood, who works for David Lloyd, said: "Rather than jumping on the diet bandwagon with a vengeance at the beginning of January, only to fall off again after a week, by adopting a healthy, balanced approach to diet and exercise, those extra pounds can be easily lost and kept off for good."
