Beat fat faster before breakfast (2013-12-04)

People can burn up to 20% more body fat by exercising in the morning on an empty stomach, according to new research from Northumbria University.

 


 

In a study published in the British Journal of Nutrition, academics sought to find out whether the known benefits of exercising after an overnight fast were undermined by an increased appetite and eating more food later in the day.
Researchers,led by Dr Emma Stevenson and PhD student Javier Gonzalez, asked twelve physically active male participants to perform a bout of treadmill exercise at 10am, either after they had eaten breakfast or in a fasted state having not eaten since the evening before.

Following the exercise all participants were given a chocolate milkshake recovery drink. Equivalent trials were also conducted where the participants did not exercise for comparison.

Later in the day, participants were provided with a pasta lunch which they were asked to consume until they felt ‘comfortably full’.
Their lunchtime consumption of energy and fat was assessed and calculated, taking into account the amount of energy and fat burned during the morning period.

The researchers discovered that those who had exercised in the morning did not consume additional calories or experience increased appetite during the day to compensate for their earlier activity.

They also found that those who had exercised in a fasted state burned almost 20% more fat compared to those who had consumed breakfast before their physical activity. This means that performing exercise on an empty stomach provides the most desirable outcome for fat loss.

Dr Emma Stevenson, Senior Lecturer in Sport and Exercise Nutrition and Associate Director of Northumbria University’s Brain, Performance and Nutrition Research Centre, said:
“Research, such as this study, is very important to help provide practical guidelines relating to food intake to individuals who are exercising to maximise fat mass loss. It must be highlighted that this is an acute study and we can only speculate on the longer term outcomes of such nutritional practices.”
