Meal Timing Matters Just as Much as What You Eat.

A 2025 narrative review in Nutrients by Reytor‑González et al. explores how when we eat interacts with our internal clocks—impacting metabolism and weight regulation. Aligning meals with natural circadian rhythms—eating more in the morning/early afternoon and less at night—may help prevent obesity and metabolic disease, even without restricting calories.

Studies show that our bodies process food differently throughout the day: insulin sensitivity peaks earlier, while late-night eating impairs glucose regulation and increases fat storage. This field of chrononutrition argues that syncing meal timing with biological clocks can boost metabolic health—whether you follow a Mediterranean diet, keto, or even a low-calorie plan.

Try shifting more of your calories to earlier in the day—enjoy a hearty breakfast and lunch, then taper off eating in the evening. Your circadian rhythm—and metabolism—will thank you.
