The Claim

In obese adults, late time-restricted eating combined with energy restriction results in greater reductions in gut microbiome alpha diversity during the intervention period compared to early time-restricted eating or energy restriction alone.

Cause and effect
1 study reviewed
In plain English

In obese adults, eating all meals later in the day while reducing calorie intake leads to a larger decrease in gut microbiome diversity than eating the same meals earlier in the day or reducing calories without changing meal timing.

See the scientific wording

In obese adults, late time-restricted eating combined with energy restriction leads to greater reductions in gut microbiome alpha diversity during the intervention compared to early TRE or energy restriction alone, suggesting meal timing later in the day may be less favorable for microbial health.

Why this might work

When people eat late in the day, their gut bacteria don't get a long enough break from food, which hurts the good bacteria that make butyrate. Without enough butyrate, the gut lining becomes leaky, allowing harmful substances to enter the bloodstream and trigger inflammation. This causes the diversity of gut bacteria to drop, especially the types that keep the gut healthy.

  1. Study: Effects of Time-Restricted Eating (Early and Late) Combined with Energy Restriction vs. Energy Restriction Alone on the Gut Microbiome in Adults with Obesity

    People who ate only between noon and 8 p.m. while cutting calories lost more types of good gut bacteria than those who ate earlier in the day or just cut calories. This suggests eating later may be worse for your gut microbes.
