There is an old Ayurvedic idea that your digestive power works like a fire, and that fire follows the sun. It is low first thing in the morning, strongest around midday when the sun is overhead, and fading by night. So the heaviest food you eat lands best at lunch, when the body actually has the heat to deal with it.
Modern research wandered into the same conclusion from a different door. We handle carbohydrates better earlier in the day, and a big late dinner tends to just sit there while you are trying to sleep. You wake up a little foggy and blame the morning, when really it was last night's 10pm plate.
The traditional rule of thumb is easy to keep: breakfast like a guest, lunch like a king, dinner like a beggar. Front-load the day. Make lunch the real meal. Keep dinner small and early enough that you are not still digesting when you lie down.
It is less about cutting things out and more about getting the timing right.
Try this: For one week, make lunch your biggest meal and finish a light dinner before 7:30pm. See how you sleep.
