Energy balance

Consuming dinner late at night (during the biological night) reduces the thermic effect of food (TEF) compared to consuming the same meal at a typical dinnertime, contributing to reduced total daily energy expenditure.

Eating your largest meal late at night is less metabolically efficient. Your body burns fewer calories digesting food at night than during the day. If you must eat late, be aware that this reduces the energy cost of your meal, potentially contributing to weight gain if you don't adjust your total intake.

The thermic effect of feeding also decreased in response to a late dinner on the first nightshift.

Why this rating

Controlled inpatient study with precise calorimetry, but limited to one late dinner event on the first nightshift.
