Exercise less for weight loss?

Finally some good news regarding weight loss…
The latest advice on weight loss is to reduce the amount of time in the gym! This may sound strange and totally inaccurate, but researchers at the University of Copenhagen say that 30 minutes of rigorous exercise can be as effective as an hour for achieving weight loss.

The study set out to discover if you can actually exercise too much. The researchers measured exercise duration and weight loss in 60 healthy but moderately overweight men aged 20 to 40 years. The men were split into three groups:

·         21 were assigned to 60 minutes of aerobic exercise comprising of a mixture of running, cycling and rowing every day.

·         21 were assigned to 30 minutes of aerobic exercise comprising of a mixture of running, cycling and rowing every day.

·         18 men were told not to exercise and remained sedentary throughout the study.

The results found that the men who were active for 30 minutes daily burned 300 kcal per session and lost 3.6 kilograms in 13 weeks. Those who exercised for an hour a day burned 600 kcal and lost 2.7 kilos. Not surprisingly, the men who remained sedentary did not lose any weight. This study was published in the American Journal of Physiology.

A possible reason for these results is that the participants who exercised for 30 minutes a day remained active throughout the day, whereas those who had a 60 minute workout were less active, as they were burnt out.

This small study shows that there really can’t be many excuses not to exercise. 30mins of regular exercise is easily manageable for most of us.

Other studies have also highlighted that shorter workouts can have beneficial results. Studies from the University of Bath and the University of Glamorgan backed this claim. These studies found that short bursts of exercise were more effective than hour long exercise sessions.
