The Diet MythTim SpectorOverlook Press, $28.95
For 10 days, Tom Spector lived off McDonald’s. He had chicken nuggets or Big Macs for meals and McFlurries for dessert. Tom, a 22-year-old student, was re-creating a version of the diet made famous in the film Supersize Me. But Tom’s plan had a twist: Before and after the diet, he gave his dad some poop.
Tom’s father, Tim, wanted...
You’ve already had a muffin. And a half. You know you’re full. But there they are, fluffy and delicious, waiting for the passersby in the office. Just thinking about them makes your mouth water.
Maybe if you just slice one into quarters. I mean, that barely counts…
And then we give in, our brains overriding our body’s better judgment. When I catch myself once again polishing off a...

The taste of certain fats.
Move over, umami. Fat is the newest member of the pantheon of basic tastes, joining salty, sweet, sour, bitter and savory, or umami.
Researchers at Purdue University in West Lafayette, Ind., conducted taste tests pitting a variety of fats against flavors in the other taste categories, such as monosodium glutamate for...
On June 16 the Food and Drug Administration made the final call: Trans fats are no longer “generally recognized as safe” for use in food. That means that food manufacturers have three years to ooze these cheap and useful fats out of their processed foods.
In fact, most of them already have. Trans fat —a big source of which is partially hydrogenated vegetable oils — has been the food...

A controversial paper about modifying genes in fertilized human eggs raised some serious ethical concerns. Tina Hesman Saey covered researchers’ arguments for and against this type of genetic engineering in “Editing human germline cells debated” (SN: 5/30/15, p. 16).
Many readers embraced the idea of making permanent changes to human DNA. “If someone wants to...
Diet smarter, not longer.
Slashing your food intake for just five consecutive days a month can yield a bounty of health benefits, according to a new study led by researchers from the University of Southern California. This briefer approach to caloric restriction, a severe form of dieting, challenges previous research that dieters might need to tighten their belts as often as twice a week...
Blair River was described as “a big guy with a big heart.” The 575-pound former high school wrestler from Mesa, Ariz., became such a fixture at the Heart Attack Grill that he was recruited to be the restaurant’s official spokesperson. His satirical ads made him a minor celebrity in central Arizona. He died in 2011 at age 29 — not because of his heart but from complications of influenza....
Fruit flies’ brains may be wired to count calories.
Several genes in the brain appear to help the flies learn to distinguish between normal-calorie and high-calorie foods — and to remember to choose the healthier option later. Feeding the flies a constant diet of high-calorie foods disrupts their ability to make these metabolic memories, researchers report April 7 in Nature...

When you eat may determine how long and strong your heart beats.
Fruit flies that limited eating to 12-hour stints had steadier heartbeats in old age than flies that ate whenever they wanted, researchers report in the March 13 Science. The study adds to a growing body of evidence that the timing of meals may be as important for health as diet composition and calorie...
A new round of dietary do’s and don’ts accompanied last month’s scientific report on the latest food research, summarizing everything from aspartame to saturated fats. The report puts eggs back on the menu. High dietary cholesterol is no longer linked to blood cholesterol in most healthy people. But what grabbed the headlines? Coffee, of course.
Many of us are happy to raise a mug to our...
