When you lose weight, where does it go?

What happens erstwhile we suffer weight? This is truly a question astir however our bodies store and usage the vigor we request to function. 

In general, we store backup vigor successful fat cells that are distributed astir the body, immoderate successful the abdomen astir the organs (visceral fat) and immoderate nether the tegument (subcutaneous fat); lesser amounts of abdominous can besides beryllium deposited successful musculus tissue. We besides person smaller reserves of vigor that are stored successful the liver, muscles, and encephalon arsenic glycogen. Glycogen is the stored signifier of glucose, the sweetener that is the body’s main root of energy. 

We usage vigor each the time, whether we’re running, eating, oregon sleeping. The vigor we usage astatine rest—to pump blood, digest food, modulate temperature, repair cells, breathe, oregon think—is our baseline metabolism, the minimum vigor required to support the body’s basal biologic functions. So if we’re carrying other weight, it’s due to the fact that we’re taking successful much vigor than we’re using. (The much-cursed thickening astir our bellies is simply a operation of accumulated heavy visceral abdominous and much shallow subcutaneous fat.)

When we expend vigor during aggravated bouts of workout and different carnal activity, the glycogen successful our muscles is utilized first. The liver releases glycogen to assistance with musculus enactment and to modulate humor glucose levels. After astir 30 to 60 minutes of aerobic exercise, the assemblage begins to pain fat.

If we instrumentality successful little vigor than the assemblage needs wide to support itself—as erstwhile dieting—then the assemblage turns much often to abdominous reserves for energy. As your assemblage metabolizes fat, fatty acerb molecules are released into the bloodstream and question to the heart, lungs, and muscles, which interruption them isolated and usage the vigor stored successful their chemic bonds. The pounds you shed are fundamentally the byproducts of that process. They are excreted successful the signifier of water—when you sweat and pee—and c dioxide, erstwhile you exhale. In fact, the lungs are the superior excretory organ for fat.

The assemblage uses vigor to transportation retired the accustomed basal processes astatine rest—again, your baseline metabolism—and for the carnal enactment you bash connected apical of that, which is considered your progressive metabolism.
