Some preliminary evidence suggests that more energy is used to process a meal when it’s eaten in the morning, compared with later in the day.
This means a person burns slightly more calories if they eat earlier.
However, it’s still unclear how much of a difference this would make to overall body weight.
Another possibility is that late-night eating extends the overall window during which food is consumed.
This gives our digestive systems less time to recuperate and reduces the opportunity for our bodies to burn fat.
