The fast metabolism myth: Here’s what actually determines how slim you are

EXCERPTS: Most of us have a friend that can eat whatever they want, whenever they want, and still somehow stay slim. They may say they’ve been blessed with a fast metabolism, but is that really the case?
[...] But weight on its own isn’t a reliable indicator for a metabolic rate, because two people who both weigh the same can have vastly different muscle mass. Physical appearance is no better metric...
[...] So why is our friend so slim? It could be inherited – genetics has a small impact on BMR – or they could be leading an active lifestyle. An unbalanced diet could be contributing to their weight loss, or they may be eating less when they’re away from your company.
Whatever the reason, you’re now armed with a retort when they say, “I’m so lucky to have a fast metabolism!” (MORE - missing details)
WHO says aspartame is a 'possible carcinogen.' The FDA disagrees

IINTRO: A committee of 25 international experts has determined that aspartame may "possibly" cause cancer in people, according to a report released Thursday by the World Health Organization.
This new classification, which is based on a review of "limited evidence," does not change the recommended limit on the daily intake of the artificial sweetener.
"Our results do not indicate that occasional consumption should pose a risk to most consumers," said Dr. Francesco Branca, director of the Department of Nutrition and Food Safety at the WHO, during a press conference in Geneva. He said the problem is for "high consumers" of diet soda or other foods that contain aspartame. "We have, in a sense, raised a flag here," Branca said, and he called for more research.
But the U.S. Food and Drug Administration says it disagrees with this new classification, pointing to evidence of safety. In a written statement, an FDA official told NPR that aspartame being labeled by the WHO "as 'possibly carcinogenic to humans' does not mean that aspartame is actually linked to cancer."
The WHO has long set the acceptable daily intake, or ADI, of aspartame at a maximum of 40 milligrams per kilogram of body weight per day. So, a person who weighs 60 kilograms (about 130 pounds), could consume up to 2,400 milligrams per day, which is roughly equivalent to 12 cans of Diet Coke — much higher than most people consume.
While the WHO is not changing the acceptable daily intake, Branca says "we're just advising for a bit of moderation." If people consume aspartame as a way to avoid sugar and control weight, "the benefit is not there," Branca says...
