Background Consumption of low glycemic index (GI) diets has been associated with a range of health benefits including weight loss. Meal plans incorporating pre‐packaged, energy‐controlled, low‐GI products may therefore be a convenient and effective intervention for weight management. However, GI is affected by the degree of food processing. This suggests that a low‐GI diet based on such foods could be difficult to construct. Objective Determine the GI of a meal plan based on a line of prepackaged foods designed to have a low‐GI. Methods Sixty‐six foods, including 16 breakfast, 15 lunch, 13 dinner and 22 snack items, were tested. Groups of ten healthy subjects tested each food once and a control food three times. The GI of test foods was calculated using standard methodology from capillary blood samples obtained at −5, 0, 15, 30, 45, 60, 90, and 120 minutes. GI for the full meal plan was estimated from tested foods and recommended supplemental grocery items. Results 49 foods fell in the low GI range, 13 in the medium and 4 high. Estimated dietary GI of the full meal plan was in the low range (GI = 44). Conclusion This study demonstrated that an energy‐controlled, low‐GI diet can be assembled using a line of pre‐packaged foods, thus providing an option in designing research or clinical interventions requiring a low‐GI diet.
