White potato meals and when you eat them: how timing changes blood sugar and appetite

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this randomized, within-subject study, adults will try six different evening meals that vary the potato side and will have their blood glucose and appetite tracked for 120 minutes after eating. The next day, energy intake will be monitored and a morning breakfast will be consumed to assess appetite and glycemic response across 24 hours. Continuous glucose monitoring is used to quantify glycemic response, and subjective appetite is measured alongside sleep and dietary intake. The goal is to see if potato type and timing of consumption influence satiety and subsequent food choices compared with meals with lower glycemic carbohydrates. Participants are healthy adults aged 18–65 with BMI 18.5–24.9 kg/m2, and the study is conducted at Toronto Metropolitan University’s Centre for Urban Innovation.
