Postprandial glucose response to identical meals varies significantly between individuals, suggesting that personalized nutrition based on glycemic response is more effective than standardized dietary guidelines focused solely on macronutrient composition.
Generic dietary advice (like 'low carb') may not work for everyone. Your body's response to specific foods (e.g., milk/cereal vs. protein bars) varies. Using CGM to test your response to specific foods can help you identify which foods cause severe glucose spikes for you personally, allowing for personalized nutrition.

The vast majority (60%) of the responses to milk/cereal were classified as severe variability, whereas the responses to the PROBAR protein bar and to bread and peanut butter varied among individuals.
