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.
After that your metabolism will slow again. So the idea is to burn as much fat from your body for fuel as possible, rather than fueling it with food, especially carbohydrate-rich foods which are converted faster to energy and will prevent the body from burning it's own fat stores first.
