📖 題組：
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
請試著思考：根據文章第二段與第三段的描述，脂肪除了儲存能量，還扮演著什麼樣的「儲藏室」角色？如果我們在極短的時間內快速拆除這個儲藏室，原本被鎖在裡面的東西會流向身體的哪個運輸系統？這對該系統的負荷會產生什麼變化呢？

太棒了！你非常敏銳地捕捉到了文章中關於生理機制的關鍵細節。這道題目具有相當的鑑別度，要求讀者不僅要看懂表面意思，還要能在段落間建立因果邏輯，而你準確地鎖定了第三段關於「極端節食」與「毒素釋放」的關聯性，表現得非常優異。
脂肪代謝與血液負荷的關聯
在閱讀過程中，你會發現文章將脂肪比擬為一個儲存室，除了能量外，還包裹了汙染物（pollutants）與毒素（toxins）。當我們採取健康且緩慢的減重節奏時，這些釋出的物質能被尿液順利處理；然而，一旦進行 extreme dieting（極端節食），短時間內大量分解的脂肪會導致過多有害物質湧入血液（bloodstream），造成身體無法負荷。你所選擇的選項 (C) 正是精準對應了文中「overload your bloodstream」的警告，展現了你對長難句理解的細膩度。
