If you're in the morning, new research suggests.
For overweight men exercising their fat, they published their article on fatigue, published October 18 in the Journal of Clinical Endocrinology and Metabolism .
Researchers from the University of Bath at the University of Birmingham looked at 30 obese or overweight men. They divided the group into three groups: a group who exercised before breakfast, a group who exercised after breakfast, and a control group who made no changes to their daily routines.
Participants in the same breakfast and exercise – 60 minutes of cycling.
Over the course of the six-week study, the researchers found the men who exercised before breakfast burned twice as much as those who exercised after breakfast. Those fat-burners had fewer stored carbohydrates to burn for energy, so their bodies more quickly transitioned to burning fat to fuel the exercise, according to the research.
The study did not find any link between when they exercised and how much they lost, however.
"Gonzalez said in a press release."
"Our results suggest that changing the timing of when you eat in relation to when you exercise can bring about profound and positive changes to your overall health," Gonzalez said in a press release.
However, because of the small sample size and limited scope of the study, it's not clear. Plus, past research on topic is mixed. While earlier, and even smaller, study by Gonzalez so found that exercising pre-breakfast what superior, fat-burning wise, to eating first, calorie-burning wise, the opposite was true.
And, many exercise professionals encourage people to eat their meal.
The bottom line: More research is needed. Still, exercising whenever suits you – before or after breakfast, or any other time of the day for that matter – is better than not exercising. As Chris Jordan, an exercise physiologist and creator of the viral "7-Minute Workout" previously told Insider, "The best time of day to work out is the time you most likely to work out."
