Diet Modification
Conditions
Brief summary
Low-carbohydrate diets (less than approximately 130 grams per day) are emerging as an efficacious treatment option with several studies supporting weight loss and remission of type 2 diabetes. Many physicians are now implementing this strategy but the time it takes to educate patients on nutrition is a barrier. The research team is working with physicians to develop a solution whereby the nutrition education and intervention is delivered via mobile/online technology (i.e., an app). This study will test whether it is feasible and efficacious for physicians to recommend this app to their patients with obesity and type 2 diabetes to help them lose weight and improve their condition.
Detailed description
The study is a non-experimental feasibility study to explore the acceptability, practicality and demand for the use of a 12-week, personalized, online program to teach and coach patients about therapeutic carbohydrate restriction for individuals with obesity and/or at risk for type 2 diabetes/with type 2 diabetes. The program is intended to enhance the usual clinical care provided for patients with these conditions and will allow for physicians to monitor patient progress through the program. Both physician and patient perspectives will be explored.
Interventions
BEHAVIORALDigital therapeutic carbohydrate restriction (TCR) program
A 12-week, personalized, online program to teach and coach patients about therapeutic carbohydrate restriction as for obesity and/or T2D (or risk of T2D). The program is intended to enhance the usual clinical care provided for patients.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The percentage of eligible patients who receive prescriptions to access the online TCR program | through study completion, an average of 9 months | Assessed through the number of voucher cards handed-out over physician documentation of eligible patient visits over the study period. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Present descriptive characteristics of patients who get prescriptions to access the online TCR program | through study completion, an average of 9 months | Assessed through program intake collected through the online program (e.g. age, sex, weight, HbA1c, chronic condition, health goals) |
| The percentage of patients who receive a prescription for TCR program that sign up and start | through study completion, an average of 9 months | Assessed through the number of voucher cards redeemed on the online program over the number of voucher cards handed-out by physicians. |
| Program drop-out as assessed by the number of patients who sign up for and start the TCR program and the number of patients who complete the full program. | Pre-program (month 0) to post-program (6 months) | Assessed through the number of patients enrolled in the program and the number of patients who complete the program through program tracking. |
| Program impact assessed through changes in weight from pre-program to post-program. | Pre-program (month 0) to post-program (6 months) | For patients who complete the program, the change in weight from program sign-up to program completion. |
| Program impact assessed through change in HbA1c from pre-program to post-program. | Pre-program (month 0) to post-program (6 months) | For patients who complete the program, the change in HbA1c from program sign-up to program completion. |
| Program impact assessed through changes in medications from pre-program to post-program. | Pre-program (month 0) to post-program (6 months) | For patients who complete the program, the change in medications from program sign-up to program completion. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Qualitative patient feedback on program acceptability | Post-program (6 months) | Qualitative semi-structured interviews with patients collecting program feedback on their experiences in the program, specifically asking about the acceptability of the program. Acceptability will be assessed through the audio-recorded responses to semi-structured interview questions, subsequently transcribed and coded using content analysis. |
| Qualitative patient feedback on program practicality | Post-program (6 months) | Qualitative semi-structured interviews with patients collecting program feedback on their experiences in the program, specifically asking about the practicality of the program. Practicality will be assessed through the audio-recorded responses to semi-structured interview questions, subsequently transcribed and coded using content analysis. |
| Qualitative patient feedback on program satisfaction | Post-program (6 months) | Qualitative semi-structured interviews with patients collecting program feedback on their experiences in the program, specifically asking about their satisfaction of the program. Satisfaction will be assessed through the audio-recorded responses to semi-structured interview questions, subsequently transcribed and coded using content analysis. |
| Qualitative physician feedback on program acceptability | through study completion, an average of 9 months | Qualitative semi-structured interviews with physicians collecting feedback on their experiences in the program, specifically asking about the acceptability of the program within their daily physician practice. Acceptability will be assessed through the audio-recorded responses to semi-structured interview questions, subsequently transcribed and coded using content analysis. |
| Qualitative physician feedback on program practicality | through study completion, an average of 9 months | Qualitative semi-structured interviews with physicians collecting feedback on their experiences in the program, specifically asking about the practicality of the program within their daily physician practice. Practicality will be assessed through the audio-recorded responses to semi-structured interview questions, subsequently transcribed and coded using content analysis. |
| Qualitative physician feedback on program satisfaction | through study completion, an average of 9 months | Qualitative semi-structured interviews with physicians collecting feedback on their experiences in the program, specifically asking about the satisfaction of the program within their daily physician practice. Satisfaction will be assessed through the audio-recorded responses to semi-structured interview questions, subsequently transcribed and coded using content analysis. |
| Characteristics of individuals who drop-out of program | through study completion, an average of 9 months | Provide descriptive statistics (e.g. age, sex, weight, HbA1c, chronic condition, health goals) of individuals who drop-out after enrolling in the program and prior to program completion. |
