Food Cues in the Eat-More Food Environment

May 22, 2022 — Our food environment has changed to contribute to the rise in obesity over the last half century. People disagree about many things in the effort to find policies to reduce obesity.

Study Says Sweeteners Prompt Food Cravings? Nope.

October 9, 2021 — Reporting on non-caloric sweeteners has more in common with reporting on religion than science reporting.

How the Brain Responds to Bariatric Surgery

July 10, 2021 — Most people – even many healthcare professionals – simply don’t get it.

Bariatric surgery changes the signaling between the brain and the gut in ways that […]

The Phantom Paradox of Obesity and Brain Function

May 27, 2021 — Two serious health concerns – obesity and loss of brain function – intersect in curious ways. Good evidence suggests that obesity in early and mid life can have a negative effect on cognition. But later in life, the story is a bit fuzzier.

Is Convenient, Pleasing Food Addictive?

January 3, 2021 — Food addiction is a concept that sticks to the popular psyche. Yet it remains scientifically controversial.

Sizzling Headlines About Brain Damage

November 29, 2019 — The PR team at the Radiological Society of North America (RSNA) hit a home run this week. They were playing in the ongoing contest to create the most misinformative but sizzling headlines about scientific research. Their winning headline was doozy: MRI reveals brain damage in obese teens. Of course, that misleading press release was only […]

Getting a Fix from Digital Screens and Food Rewards

April 7, 2019 — Is it mere coincidence that the rise of digital screen time has moved in parallel with the rise in obesity? A new paper points to a possible explanation.

Choosing to Eat and Breathe and Control Your Weight

February 28, 2019 — Choosing is something that people hold dear. Even if we’re not always good at it. So, quite naturally, when people assume that obesity is all about food (not exactly true), they assume that the answer is better food choices. But a new review from Trends in Cognitive Sciences gives us reason to pause and think. […]

How a Person Gets Wired for Obesity

January 21, 2019 — New research published last week in Cell offers a glimpse of how a critical part of the brain gets wired for obesity very early in life. Sebastien Bouret, a senior author, explains: We know that the brain, in particular an area called the hypothalamus, has a very important role in the regulation of food intake […]

Looking for the Best Exercise for Brain Health?

December 11, 2018 — High intensity interval training (HIIT) just got another boost in the scientific literature. A new study in Experimental Biology and Medicine tells us that HIIT might be especially helpful for brain health in people with obesity. Small Study, Surrogate Endpoint This is a fascinating study. Researchers evaluated the effect of HIIT and more moderate exercise […]
