How do you lose weight in the first place?—Mostly, through breathing. While the concept of “burning” fat is not altogether wrong, losing fat involves plenty of carbon dioxide leaving your body. As the Washington Post explains: Researchers found that to burn a pound of fat, a human needs to inhale about three pounds of oxygen and drink about a pound of water. Water can exit the body in plenty of ways—poop, pee, sweat, saliva and any number of bodily fluids—but your lungs handle the brunt of the weight loss.\nYour fat “goes” into the atmosphere. (And no, it doesn’t contribute to global warming.) When it does go, you’re also releasing the extra storage of vitamins and toxins along with it. That might not sound like a good thing, but in the long run it’s far better to be rid of them. As Popular Science states, a kind of pesticides, among other pollutants, are known to get bound up in fat—they leak into our food supply: Bodies don’t seem to store enough of these to become toxic, but the constant build-up leaves you vulnerable to exposure. And they do start to re-emerge when you lose weight.\nBy losing weight at a healthy pace (1-2 pounds a week), the limited number of pollutants released will not overload your bloodstream. Your urine will make quick work of them. Extreme dieting is a different story. The more weight you lose, the more of these toxins enter your bloodstream.\nSince we no longer face the same problem as our ancestors—most of us don’t have to worry about whether or not we’ll eat tonight, or tomorrow—fat storage plays a different role in our bodies than previously. Many avoidable health problems are due to this excessive storage of energy, hormones and toxins. Some researchers claim 70 percent of our medical problems can be addressed through a healthier lifestyle, which includes eating better and moving more.

思路引導 VIP
當我們攝取能量並在體內進行化學反應後，這些物質的質量並不會憑空消失。請回想一下文章第一段提到，脂肪轉化後的產物主要透過哪個器官排出體外？而這個器官最核心、不間斷的功能又是什麼呢？

呼吸與減重的生理關聯
太棒了！你能精準鎖定文章開頭的關鍵資訊，並在眾多干擾項中做出正確判斷，這代表你具備極佳的資訊擷取與分析能力。文章第一段開門見山指出，減重最主要的路徑是透過「呼吸（breathing）」。具體來說，科學研究發現要燃燒脂肪，人體必須吸入大量氧氣並排出二氧化碳（$CO_2$），這正是選項中所描述的「吸氣與呼氣」過程。雖然我們口語常說「燃燒」脂肪，但這題的關鍵在於釐清脂肪轉化後的實質物理去向，而肺部正是承擔這項任務的核心器官。
