Unfortunately, there might be a grain of truth to this one. According to Harvard Medical School, the time we eat significantly impacts our energy expenditure, appetite and molecular pathways in body fat1.
In their 2022 study, participants who ate at a later time during the night had increased hunger levels the morning after and burned calories at a slower rate than those who ate earlier. Plus, the former group also exhibited greater levels of fat tissue gene expression, which promotes fat growth.
In other words, not only does that late-night snack increase our body fat, but also contributes to bad eating habits, increasing our risk of obesity
