Study shows intermittent fasting reshapes gut‑brain link as Bible‑based diet trends online in Brazil

Chinese researchers who tracked 25 obese adults on a strict intermittent‑fasting regimen reported that participants lost an average of 7.6 kilograms and showed simultaneous changes in gut microbiota and brain regions linked to hunger and behavioral control. Functional MRI revealed reduced activity in appetite‑related areas, while beneficial bacteria such as Faecalibacterium and Parabacteroides increased and Escherichia coli decreased, suggesting a bidirectional gut‑brain communication during fasting.

Meanwhile, a diet inspired by biblical food habits is gaining momentum on Brazilian social‑media platforms. Influencers promote five core ingredients – olive oil, fish, lentils, honey and naturally leavened sourdough bread – as natural, minimally processed alternatives to modern processed foods. Nutrition experts note the emphasis on these foods aligns with recommendations for cardiovascular health, metabolic control and nutrient density, fueling the trend's rapid online popularity.
