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.
So our metabolisms are hardwired to expect a nightly fast, which is a key time for your body to burn fat. Here's how that works: During the day, your brain and muscles use some of the calories you eat for fuel, and the rest gets stored in the liver in the form of glycogen. At night, your body converts that glycogen into glucose and releases it into your bloodstream to keep your blood-sugar levels steady while you sleep.
