A recent study in the Journal of Nutrition Education and Behavior (JNEB), published by Elsevier, found that adolescents reported TikTok food content cued their desire to eat or try foods, while acknowledging that parents could play a protective role by helping them disengage from the platform and fostering critical conversations about food, bodies, influencers, and online health information. Participants frequently described TikTok food content as prompting hunger, cravings, and interest in trying new foods, while parental involvement could interrupt exposure to food-related content.

According to a peer-reviewed study published May 29, 2026 in Nutrition & Diabetes, adults with overweight or obesity (mean BMI: 33.6 kg/m²; mean age: 47.7 years) who reported continuing to eat pork while participating in a 6-month digital weight management program lost a clinically significant 5.3% of starting body weight and improved their overall diet quality scores by 4.3 points. The study was a secondary longitudinal analysis of 187 adults enrolled in the Weight Watchers digital program between January and November 2023.

A new study published in Life Metabolism reports that a single post-meal blood biomarker, 1-hour postprandial SPARC (SPARC-1H), can predict who will benefit most from adopting a Mediterranean diet. The discovery provides one of the clearest examples to date of how precision nutrition can identify individualized dietary responses using a simple blood test rather than complex multi-omics models.

The number of Australian women receiving intravenous iron treatments has surged dramatically over the past decade, with new research revealing that one in 20 women of reproductive age received intravenous iron in 2024.

Osaka Metropolitan University researchers discovered that the mitochondrial protein OPA1 in hypothalamic MC4R neurons plays a vital role in controlling fat intake and body weight in mice. The study also highlights significant sex differences in obesity-related responses, offering new insight into the neural regulation of energy balance.
