Surprise, surprise: My New Year's resolution is to get rid of that spare tire I acquired over the holidays. (I'm a sucker for eggnog.) I'm curious: Are there ways to lose weight that are better for the environment than others? -Feeling Too Chunky To Print My Name Don't despair, Chunky! If you're feeling about as round as the Earth right now, you're not alone: Losing weight regularly tops the list of most popular New Year's resolutions; not surprising, considering that over two-thirds of American adults are overweight or obese. Given the, ahem, enormity of the problem, it's important to note that the method of weight loss is somewhat moot. It's the losing weight part that matters, at least where the planet is concerned: Worldwide obesity is adding an estimated 1 billion extra metric tons of greenhouse gas emissions to the atmosphere each year, thanks to higher fuel and food demands of the overweight.
