The Tyrannosaurus rex of "Jurassic Park" fame chases any prey that moves, then devours it with a bone-crushing gnash of its enormous jaws and serrated teeth. But paleontologists don't necessarily back Steven Spielberg's portrayal of T. rex , with some saying it may have simply scavenged the remains of dead animals it happened to find. Now scientists have unearthed what they say is the first direct evidence that the dinosaur king hunted its prey, further supporting its reign at the top of the Cretaceous food chain.

Bryan Piperno was just 9 years old when he began keeping his secret. The Simi Valley youngster tossed out lunches or claimed he ate elsewhere. As he grew older, he started purging after eating. Even after his vomiting landed him in the emergency room during college, he lied to hide the truth. Piperno, now 25, slowly fended off his eating disorder with time and care, including a stay in a residential treatment facility. But surveys show a rising number of teenage boys in Los Angeles now struggle with similar problems.

A new diet drug went on the market Tuesday. It's expensive and has to be taken the rest of the patient's life to continue to work. It comes with a long list of possible side effects, including common ones such as dizziness, fatigue and constipation, or rare ones such as hallucinations or memory loss. On average, it doesn't have much effect on a person's weight. So what is there to love about Belviq? Doctors have been clamoring for another “tool” they can use in the fight against obesity, and if Belviq, which suppresses appetite, is only a lightweight hammer of a tool, even those are of use to some people.

If a doctor is going to tell a patient he's obese and needs to lose weight, that patient seems more likely to trust the advice if the doctor is overweight too, scientists say. It might seem that patients want role models in their primary care doctors, but in matters of weight, that doesn't seem to be the case. Researchers from John Hopkins Bloomberg School of Public Health set out to see what effect a doctor's weight might have on patients; they published their findings in the June issue of Preventive Medicine.

After a dinner of pasta from Italy sauced with artichokes that had been grown here, then shipped to the East Coast for canning before being shipped back, and a salad with fennel from Mexico and lettuce from goodness-knows-where, my family and I sat down at our kitchen table to argue over a shopping list. We have agreed to purchase only local foods for the month of June, but were having second thoughts after I discovered the cost of a locally raised, pastured chicken - a steep $35. I guess we won't be eating much meat.

What is gluten? Gluten is a protein that is found in certain grains, including wheat, barley and rye and triticale (a cross between wheat and rye). What problems prompt people to avoid gluten? Gluten causes inflammation of the small intestine in people with celiac disease, which is an autoimmune disease diagnosed with a blood test or biopsy; other symptoms include digestive problems, anemia, fatigue, headaches and joint pain. Avoiding gluten is the treatment, though there is no cure.

Attention dieters: If you want to maximize your chances of success, don't go to the grocery store on an empty stomach. So says a new JAMA Internal Medicine study from two members of the Cornell University Food and Brand Lab , where researchers investigate “the psychology behind what people eat and how often they eat it,” as this website puts it. The study authors - Brian Wansink and Aner Tal - asked 68 study subjects to fast for...

Think of the adage that if you want something done, get the busy person to do it. People who change their diet and start exercising at the same time - as opposed to doing them one at a time - were more successful, researchers at Stanford School of Medicine found. Few studies have looked at dietary change and exercise together, and the few studies that look at how to introduce more than one healthy change into people's lives are conflicting, the researchers said in the journal Annals of Behavioral Medicine.

The patient in his 50s was mildly overweight, had high cholesterol and was headed down the road to diabetes. Common problems, and his doctor made the usual recommendation: medications. But the patient, Michael Mosley - a British author, journalist, TV personality and doctor himself - decided to go a different route. He traveled around his own country and ours, interviewing leading researchers, then tested some of their latest findings. The result? "The Fast Diet," a bestselling book in Britain (it has nothing to do with fast food, how fast you eat or even how fast you lose weight)

As a student at Emory University School of Medicine in Atlanta, Timothy Harlan was often struck by how little the medical professionals around him seemed to know about healthful eating. Doctors would tell their patients what foods to avoid, but rarely did they advise them on the foods they should embrace. It seemed strange to Harlan, who had been a foodie since childhood and opened his own French bistro, Le Petit Cafe, when he was 22. So Harlan-the-medical-student channeled Harlan-the-chef and wrote “It's Heartly Fare,” a guide to healthful eating.
