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.

古今生活型態的轉變
這題的核心在於釐清文章提到的「古今差異」。在最後一段的開頭，作者明確指出：“most of us don’t have to worry about whether or not we’ll eat tonight, or tomorrow”，這句話直接點出了現代人與祖先在生存壓力上的不同，亦即我們擁有穩定的食物來源，這正好對應了選項 (B) 的內容。這也是為什麼文章接著提到，現代人的脂肪儲存扮演了與以往不同的角色。
