The same portion consumed at 8pm could spike glucose by 50-60 points. Identical food, same quantity, vastly different metabolic impact. These timing differences reflect our body's natural circadian rhythms. Insulin sensitivity naturally fluctuates throughout the day, following patterns that evolved over millions of years when h...
