Chrononutrition
The science of how meal timing interacts with your body clock to influence metabolism and weight.
Plain English
Patient-Friendly Explanation
Chrononutrition is the science of how the timing of your meals affects your metabolism and weight. It is based on the idea that your body processes food differently depending on the time of day — eating larger meals earlier and lighter meals in the evening may support better weight management. This approach works with your circadian rhythm, your body's internal 24-hour clock.
Medical
Clinical Definition
Chrononutrition examines the interplay between meal timing, circadian biology, and metabolic health. The circadian clock regulates key metabolic processes — insulin sensitivity peaks in the morning and declines through the day, while melatonin release in the evening impairs glucose tolerance. Clinical studies demonstrate that consuming a larger proportion of daily energy intake earlier in the day (front-loaded eating) improves glycaemic control, enhances diet-induced thermogenesis, and promotes greater weight loss compared to isocaloric evening-heavy eating patterns.
Key Insight
Why It Matters
Chrononutrition offers a practical, non-restrictive strategy for weight management — it is not just about what you eat, but when you eat. Dr. Joseph Wang can help you structure meal timing around your lifestyle and circadian rhythm for more effective weight-loss results.
