The truth is that there's no reliable evidence to suggest that calories are burned more efficiently at certain times of day. But the time of day can influence how you feel when exercising.
The most important thing, experts say, is to choose a time of day you can stick with, so that exercise becomes a habit.
The Perks of Morning Exercise
If you have trouble with consistency, morning may be your best time to exercise, experts say.
"Research suggests in terms of performing a consistent exercise habit, individuals who exercise in the morning tend to do better," says Cedric Bryant, PhD, chief science officer with the American Council on Exercise in San Diego.
"The thinking is that they get their exercise in before other time pressures interfere," Bryant says. "I usually exercise at 6 a.m., because no matter how well-intentioned I am, if I don't exercise in the morning, other things will squeeze it out."
He recommends that if you exercise in the morning, when body temperature is lower, you should allow more time to warm up than you would later in the day.
