not necessarily so if you exercise at a particular level of intensity you'll burn the same number of calories regardless of when you exercise says neil pire director of the school of total athletic development. here,pire covers the pros and cons of morning vs. evening workouts.
the early-bird advantage
-surveys report that the majority of people who exercise regularly do it in the morning. so the odds are in favor of sticking with it if you exercise in the morning
-many people find that morning exercise regulates their appetite for the day. for example they aren't as, hungry and they make better food choices
-if you exercise, at about the same time every day your body's endocrine system and circadian rhythms adjust to this regular behavior. as a result, it's easier to wake up and your metabolism and all the hormones involved in exercise begin to rise while you're sleeping. thus you are more alert to exercise when you do walk up.
-research has shown that exercise increases mental acuity. on average it lasts 4 to 10 hours after a workout.
