Is this trial a fit for you?
✓Likely a good fit
Adults aged 30 to 65 who had an ischemic, hemorrhagic, or transient ischemic attack within 1–14 days, have confirmed prediabetes or type 2 diabetes, are medically stable, English-speaking, and able to use a smartphone or a study-provided iPhone are ideal candidates.
✕Probably not a fit
Patients with severe dysphagia that prevents oral intake, type 1 diabetes, significant cognitive impairment preventing consent or app use, inability to attend study visits, or who are pregnant or breastfeeding are unlikely to benefit or be eligible.

What this trial studies
This randomized controlled pilot will enroll 40 adults with a recent stroke and confirmed prediabetes or type 2 diabetes from Queen's Medical Center and randomize them to the PortionSize Ed intervention or standard care. The intervention includes a mobile app with portion-size education, weekly reminders, educational videos, brief weekly food logs, and three counseling sessions with a registered dietitian over 12 weeks. Researchers will collect usability and engagement data and measure changes in diet adherence as well as cardiometabolic outcomes (HbA1c, lipids, blood pressure) and body composition at baseline and 12 weeks. Visits include in-person baseline and 12-week assessments (DXA, BIA, 3D optical scan, fingerstick labs) and a virtual 6-week follow-up.
Why it matters
Potential benefit: If successful, the app could help participants improve diet quality and cardiometabolic markers, which may lower the risk of future strokes.
How similar studies have gone: Prior research shows Mediterranean diets and some mobile health nutrition programs can improve cardiometabolic risk factors, but using a portion-size app with dietitian support in the early post-stroke period is relatively novel and not well established.
