A study has suggested that middle-aged women require around an hour's exercise a day in order to lose weight through exercise.
Conducted by a team of researchers from the University of Harvard, the study looked at around 35,000 women over the course of 13 years.
All of the women had an average diet, but their levels of physical activity varied.
At the end of the study, those women who undertook an average of 60 minutes exercise a day were the ones who maintained a health body mass index of under 25.
Steve Halsall, fitness expert from the Mirror.co.uk and fitness entrepreneur, said that while the hour a day result was "probably an accurate statement", it was still "a big ask" for people with busy lifestyles to fit in this much exercise.
However, Mr Halsall added that, for those who are pushed for time, "mad cross training sessions" are a very effective form of weight loss exercise as they "hit calories and your metabolism further than anything else".
