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.
Another answer Your body will burn fat first, it isn't until you have depleted a great deal of stored fat that your body will begin to break down muscle. You will, however, lose muscle if you don't use it, but this is not because your body is in starvation mode.at and energy stored in the liver is burnt off through the frist 30 mins. of exercise. Then, after that, it is where ever available fat is or where a workut is targeting it (ex: crunches will target the abs). New Answer.
