EXERCISE AND WEIGHT LOSS:
Among people who have maintained weight loss, 68% maintain a consistent workout schedule and 47.8% exercised first thing in the morning, suggesting consistent morning exercise may be helpful for weight management.
If you’re in the habit of using time restricted eating, exercising before your first meal of the day will also allow you to take advantage of fasted exercise, which has a number of important metabolic benefits.
Exercising while in a fasted state boosts fat shedding and maximizes the impact of AMPK, which not only forces the breakdown of fat and glycogen for energy but also plays an integral role in autophagy.
Exercise and fasting together also yields acute oxidative stress, which benefits your muscle, and trigger production of brain-derived neurotropic factor (BDNF), which helps rejuvenate your brain.
Exercise can cause shifts in your circadian rhythm. The magnitude and direction of that shift depends on the time you exercise. Exercising at 7 a.m. or between 1 p.m. and 4 p.m. will shift your body clock to an earlier time. When exercising between the hours of 7 p.m. and 10 p.m., you shift your body clock to a later time.
Fasted exercise is also a potent prevention strategy for Type 2 diabetes. In one 2010 study,14 those who exercised fasted increased their levels of GLUT4 — a muscle protein that plays a pivotal role in insulin sensitivity by transporting glucose into the cell — by 28%, compared to those who had a carb-rich meal before training, or controls (who did not train).
According to the authors:
“This study for the first time shows that fasted training is more potent than fed training to facilitate adaptations in muscle and to improve whole-body glucose tolerance and insulin sensitivity during hyper-caloric fat-rich diet.”
Since exercise increases in your adrenaline level, heart rate and body temperature, it could make it difficult to fall asleep. That said, evening exercise does work well for some people and, consistency is the most important component for success.
A study found that when people exercised vigorously for 35 minutes right before bed they slept just as well as on nights when they didn't exercise. The proportion of non-rapid eye movement (nREM) sleep was greater after the exercise day than the control day.
Similarly, a poll by the National Sleep Foundation found that 83% of people said they slept better when they exercised (even within four hours of bedtime) than when they did not.
