Mayo Clinic writes that being active is an important part of any weight-loss or weight-maintenance program. If you are active, your body uses more energy, or calories. And if you burn more calories than you consume, you lose weight loss. In a news release on Jan. 24, 2013, Northumbria University has reported, Lose fat faster before breakfast. According to new research from Northumbria University people can burn up to 20% more body fat by exercising in the morning on an empty stomach.
In this study researchers 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 that day. Dr Emma Stevenson and PhD student Javier Gonzalez led a research team which 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 prior evening. After the exercise all of the participants were given a chocolate milkshake recovery drink.
Later that day, the participants were provided with a pasta lunch which they were asked to consume until they felt ‘comfortably full’. It was discovered by the researchers that those participants who had exercised in the morning did not consume additional calories or experience increased appetite during the day to compensate for their earlier activity. It was also discovered that those participants who had exercised in a fasted state burned almost 20% more fat compared to those who had consumed breakfast before their workout.
This means that the most desirable outcome for fat loss comes from performing exercise on an empty stomach. Javier Gonzalez, who is currently undertaking a PhD in Exercise and Metabolism, has said, “In order to lose body fat we need to use more fat than we consume. Exercise increases the total amount of energy we expend and a greater proportion of this energy comes from existing fat if the exercise is performed after an overnight fast. Our results show that exercise does not increase your appetite, hunger or food consumption later in the day and to get the most out of your session it may be optimal to perform this after an overnight fast.”
