From Wikipedia, the free encyclopedia. Climate ethics is an area of research that focuses on the ethical dimensions of climate change (also known as global warming), and concepts such as climate justice.
After you do a vigorous or long workout, your blood and muscle glucose will be much lower than before you started. Low glucose stores signal the body to burn fat preferentially. So after hard exercise that uses a lot of glucose, the body switches to burning fat. That's why all energy expenditure is important, not just fat burning during exercise.
A lot of energy is not used during aerobic exercise, so the body will burn fat by converting it into sugar for the cells to use as energy. If aerobic exercise is sustained for more than 20 minutes, it is especially healthy because the body will continue to burn fat for several hours afterward.
