Time-restricted eating has become popular because the method does not require calorie counting. Instead, it involves eating within a fixed time window each day.
For many people, this has made dietary changes easier to maintain in a busy daily life.
However, a new study published in BMJ Medicine shows that the timing of meals can have a significant impact on how the body responds to diet.
Why timing matters
The study is a meta-analysis conducted by researchers at National Taiwan University.

They reviewed randomized controlled trials from several countries and analyzed how time-restricted eating affects metabolism.
The results show that the method generally leads to better metabolic health than conventional eating patterns.
The effect is comparable to other structured diets, but many participants found the method easier to follow over time.
Timing rather than duration
The key finding is that not all forms of time-restricted eating work in the same way.

The study indicates that people who eat earlier in the day achieve better results than those who eat late.
Improvements are seen, among other things, in blood sugar regulation, body weight, and cardiovascular health indicators.
When late meals are combined with long eating windows, the results are significantly worse.
Shorter eating windows later in the day did not produce the same consistently negative effects.

What does this mean in practice?
According to the researchers, the results are linked to the body’s biological circadian rhythm.
Metabolism is better able to handle food earlier in the day than late in the evening.
The study’s senior author, Professor Ling Wei Chen, emphasizes that future focus should not only be on how long people eat, but also on when they eat.Late Eating Undermines Benefits of Time-Restricted Diets, Study Finds
