As the saying goes, timing is everything. And when it comes to eating, aligning your meals with your natural circadian rhythm — the highly elaborate physiological system that coordinates your sleep-wake cycle and all the hormones and metabolic processes tied to that — may just help you function optimally and lead to many health improvements.
The evidence suggests that our bodies may do best when we eat more in the morning than at night, a pattern that’s vastly different from how most Americans eat. Timing our meals this way may lead to better body weight, hormone regulation, blood sugar and cholesterol levels, sleep patterns and other metabolic improvements.
