SKIPPING either breakfast, lunch or the evening meal may help people exercise more, a study suggests.
Researchers found mice that ate just twice a day spent more time running on a cage wheel.
They say cutting out snacking and one daily meal could get fatties off the couch and losing weight.
Levels of the “hunger hormone” ghrelin are known to rise after periods without food. Now tests show the hormone may also boost exercise motivation.
Japanese scientists compared mice given unlimited food access to those fed twice a day. Both ate similar amounts but mice on a time-restricted diet ran a lot more.
Those given a dose of the hormone then upped their run rate further.
Study leader Dr Yuji Tajiri said ghrelin-like drugs may aid weight loss in humans.
He added that the findings “suggest hunger may also be involved in increasing motivation for voluntary exercise when feeding is limited”.
Dr Tajiri said: “Maintaining a healthy eating routine with regular mealtimes or fasting could also encourage motivation for exercise in over-weight people.”
