A patient with recurrent postprandial hyperglycemia reports switching to meals high in refined carbohydrates but also snacking frequently. Evaluate why this dietary pattern worsens postprandial glycemia and recommend a physiologically grounded dietary change.

• A. Snacking frequently stimulates glucagon repeatedly and is therefore protective against hyperglycemia; recommend eliminating protein from snacks to prevent insulin secretion.
• B. Refined carbs cause rapid glucose absorption and large insulin spikes; frequent snacking prevents return to baseline and promotes repeated insulin secretion leading to greater overall hyperglycemia and insulin resistance. Recommend meals with low glycemic index carbohydrates, added fiber/protein/fats to slow absorption and reduce glycemic excursions.
• C. Switching to only liquid calories will solve the problem because liquids do not affect insulin or glucagon and are absorbed without altering blood glucose levels in any meaningful way.
• D. Refined carbs are beneficial because they cause the pancreas to stop producing hormones, thereby stabilizing long-term blood glucose; recommend increasing refined carbs to reduce variability.
