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.
When you exercise, your body uses available calories from carbohydrates for energy first. Once carbs have been depleted, triglycerides are released from fat cells to supply additional energy to fuel your physical activity. Since you need to burn 3,500 calories more than you consume in order to burn one pound of fat, you're technically burning both calories and fat.
