Energy balance

Combining two specific night eating habits—dinner within 2 hours of bedtime and snacks after dinner (each occurring ≥3 times/week)—significantly increases the odds of developing obesity (BMI ≥25 kg/m²) and dyslipidemia in both men and women, with a supra-additive interaction effect observed in women.

If you frequently eat dinner within 2 hours of bed and snack after dinner (3+ times a week), you are at a significantly higher risk for obesity and high cholesterol, especially if you are a woman. To mitigate this, try to finish your last meal earlier in the evening and avoid late-night snacking. This is particularly important for women, where the combination of these habits showed a synergistic negative effect.

GoodSupportsHIGH confidence
When obesity was evaluated using BMI ≥25 kg/m2 as the cut-off, we observed that participants with both night eating habits had higher odds of developing obesity than those with neither habit (multivariable-adjusted OR, 2.11; 95% CI, 1.42–3.15 for men and 3.02; 95% CI, 1.72–5.29 for women)... In men and women, having both night eating habits was associated with dyslipidemia.

Why this rating

Large longitudinal cohort (n=8153), multivariable-adjusted, but observational design prevents causal inference.
