Eating earlier in the day for 4 days increased the activity of a gene related to cell growth and metabolism in the evening for overweight people compared to eating throughout the day.
Scientific Claim
Early time-restricted feeding increased evening MTOR gene expression by 9% in overweight adults after 4 days of intervention compared to a control schedule.

Assessment Explanation
This is a randomized controlled trial with direct measurements of gene expression. The verb 'increased' is appropriate for this specific short-term effect.
Source Excerpt
“eTRF also increased levels of SIRT1 (10 ± 3%; p = 0.004) and LC3A (22 ± 5%; p = 0.001) in the morning and increased levels of MTOR (9 ± 3%; p = 0.007) in the evening.”
Evidence from Studies
Supporting Evidence (1)
The study measured MTOR gene expression in the evening and found a statistically significant increase with eTRF. MTOR is a nutrient-sensing protein that regulates cell growth.
