Your weekend meal schedule may matter more than you think

In a prospective analysis of 104,806 adults from the NutriNet-Santé cohort, greater differences in meal timing between weekdays and weekends were associated with higher risks of cardiovascular disease and coronary heart disease in men over a median 8.1 years. The associations were strongest when weekend eating shifted earlier, while delayed weekend eating was linked specifically to coronary heart disease, with no association detected for cerebrovascular disease.

Seafood at breakfast stood out in a study of nearly 6,000 adults

Researchers analyzed dietary and sleep data from 5,975 Japanese adults to examine whether seafood, EPA, and DHA intake at different meal occasions was associated with chronotype and social jetlag. Higher intake at breakfast showed the strongest association with earlier sleep timing and less social jetlag, although the cross-sectional design cannot establish whether dietary timing influences sleep patterns or vice versa.

Time zone changes disrupt vital gut bacteria during travel

A dream holiday, an exotic destination, a long-haul flight, and finally some well-deserved rest. The problem is that many travelers arrive at their destination only to spend the first days of their vacation struggling with fatigue, sleep disturbances, low energy levels, and digestive issues.

Study finds greater social jetlag linked to a later eating pattern

In a 14-day study of 101 healthy UK adults, greater social jetlag was associated with a later distribution of energy intake, particularly greater late-evening intake among women. The effects were modest, varied by sex and day type, and did not establish whether total daily energy intake differed between groups.

Study tests chronotype’s liver link and finds no significant association

Researchers found no significant association between chronotype and FibroScan-derived liver fat or stiffness in 119 medication-naïve adults with overweight or obesity. The exploratory findings cannot exclude smaller effects, particularly for fibrosis, and require confirmation in larger longitudinal studies.

Gut microbiota may shape eating behavior and guide new obesity treatments

The review shows how gut microbiota may influence appetite, food reward, inflammation, and energy balance through the gut-brain axis. Microbiota-targeted approaches could support future treatments for obesity and eating disorders, but clinical evidence remains limited.

Eating earlier in the day is linked to lower nighttime glucose in gestational diabetes

A secondary analysis of a randomized trial examined whether the timing of the first daily meal affects 24-hour glucose patterns in pregnancies with gestational diabetes. Earlier first meals were associated with lower nocturnal glucose levels and an earlier daily glucose rhythm, although overall glycaemic control metrics were similar between groups.

Big breakfast study reveals protein curbs appetite but fiber delivers stronger gut microbiome benefits

A randomized crossover weight loss trial in adults with overweight or obesity found that higher protein big breakfasts improved satiety, while higher fibre breakfasts produced slightly greater weight loss and more favourable gut microbiota markers. Both diets improved metabolic biomarkers, but microbiota changes reflected surrogate gut health indicators rather than direct clinical outcomes.
