The researchers calculated that the meal given in the morning took about 300 calories to digest, whereas the exact same meal given at night used only about 200 calories to process. The meal itself was about 1,200 calories, so, when given in the morning, it ended up providing only about 900 calories compared to around 1,000 calories at night.2837 Same meal, same food, same amount of food, but effectively 100 fewer calories when consumed in the morning. So a calorie is not just a calorie. It depends on when it’s eaten.
