Intervention
Other:
• Common bean baked snack
Participants with normal weight (n=18) and with overweight (n=18) will attend the institute after 10-14 h fasting. Initially, they are going to complete a physical activity questionnaire, and the first visual analog scale (VAS) of subjective satiety questionnaire followed by a finger-prick blood sample. Immediately, they will be instructed to consume 40 g of the preload (common bean baked snack, cooked beans or white bread) along with 100 mL of water within 10 min. The VAS and blood glucose will be measured every 15 min after starting to eat the test food. Another VAS will be used to assess the palatability of the preload products. After 45 min, an ad libitum meal consisting of freshly prepared sandwiches and 250 mL of water will be served in a single portion. Finally, the VAS of subjective satiety is going to be assessed again.

• Anhydrous glucose (first session) (for glycemic index determination)
Participants with normal weight or overweight (n=10) will attend the institute after 10-14 h fasting. At first, two baseline finger-prick blood samples will be collected with 5 min between the samples. Then, they are going to consume a reference glucose solution containing 25 g of anhydrous glucose per 250 mL of water within 12-15 min. Later, finger-prick blood samples will be taken at 15, 30, 45, 60, 90 and 120 min after starting to drink the reference glucose solution. Areas under the glucose response curves (iAUC) will be calculated using the trapezoidal rule, ignoring the areas below the fasting value.
• Anhydrous glucose (second session) (for glycemic index determination)
Participants with normal weight or overweight (n=10) will attend the institute after 10-14 h fasting. At first, two baseline finger-prick blood samples will be collected with 5 min between the samples. Then, they are going to consume 54 g of common bean baked snack with 250 mL of water within 12-15 min. Later, finger-prick blood samples will be taken at 15, 30, 45, 60, 90 and 120 min after starting to eat the test food. Areas under the glucose response curves (iAUC) will be calculated using the trapezoidal rule, ignoring the areas below the fasting value.
