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.
Exercise burns fat by creating a calorie deficit. To reduce body fat you must burn more calories than you take in on a regular basis, and exercise burns calories. Cardiovascular exercises like walking or running elevate your heart rate, and the higher your heart rate, the more calories you will burn.
