A Weigh In on the Weight-Loss Wars

5 Jan

Just in time for our resolutions to start chugging their way to their respective early deaths, Tara Parker Pope’s story on why permanent weight loss is often a pipe dream rears its head, a monster of a magazine feature that’s as depressing as it is illuminating.

“The Fat Trap,” one of this week’s most e-mailed stories, examines what happens to the body after weight loss. Instigated by the research of a physician from the University of Melbourne, the story details why motivated people have so much trouble maintaining their weight loss.

And trouble is putting it lightly.  Joseph Proietto’s study proved the body basically launches a hormonal assault, upping the hunger hormone, ghrelin, weakening peptide YY, responsible for satiation, and lowering leptin, the hormone tasked with appetite suppression and metabolism activity. In other words, after weight loss, your body’s hormones fight to bring the fat back. An hunger does nothing for one’s preoccupation with food. It’s a vicious attack against the best intentions.

Sweet Serotonin: The Brain-Stomach Ties That Bind

29 May

Maura Lynch‘s post on Elle.com about emotional eating digests the theory that bliss begins when food hits lips. Anyone watching their weight knows the perils of mindless eating, but when your mood is the driver behind the trip to the fridge, or the cabinet-raid, it’s far from mindless. Emotions seem to dictate action for our own mental wellness. Says Emeran Mayer, director at the Center for Neurobiology of Stress at UCLA, “When we ingest something, it doesn’t just sit in our stomachs. It most certainly has an affect on our overall being.”

The post’s other points about the stomach essentially being a second brain are important, and the tenet of neurogastroenterology.

26 May

LiveScience’s post on a study that linked testosterone to skepticism in women is fascinating. The suggestion that this hormone balances oxytocin, the hormone of bonding and trust, implies that it helps boost social skills, leading to advantageous business and economic outcomes.
