Exhaled Pounds: How Fat Leaves the Body When you lose weight, where does it go? Turns out, most of it is exhaled. In a new study, scientists explain the fate of fat in a human body, and through precise calculations, debunk some common misconceptions. Fat doesn't simply "turn into" energy or heat, and it doesn't break into smaller parts and get excreted, the researchers say. In reality, the body stores the excess protein or carbs in a person's diet in form of fat, specifically, as triglyceride molecules, which consist of just three kinds of atoms: carbon, hydrogen and oxygen. For people to lose weight, their triglycerides must break up into building blocks, which happens in a process known as oxidation. When a triglyceride is oxidized (or "burned up"), the process consumes many molecules of oxygen while producing carbon dioxide (CO2) and water (H2O) as waste products.

Contrary to what might be expected from environmental concerns related to global warming, CO2 (carbon dioxide) health effects and benefits for the human body are innumerable. Life originated and had existed on Earth for millennia under conditions of very high CO2 content of the surrounding air. According to published studies, CO2 content was up to about 7-12% in air when the first creatures with lungs were evolving. Therefore, these creatures could experience all CO2 health benefits that are listed below. Note that very large CO2 concentrations (20% and more) produce adverse effects in humans and pure CO2 is a toxic gas. This web page is focused on typical or physiological CO2 levels in the lungs which range from about 20 to 50 mm Hg or from about 2.7 to 7.5%. Having a normal level of CO2 in the lungs and arterial blood (40 mm Hg or about 5.3% at sea level) is imperative for normal health. Do modern people have normal CO2 levels? ? When reading the table below note that levels of...
