Health Coaching in Primary Care Helps Patients Lose Weight and Lower Blood Sugar
Wednesday, July 8, 2026
A recent study tracked 364 adults who received dietitian‑led coaching in their regular doctor’s office. Researchers examined health records and questionnaires to assess changes in:
- Weight
- Body Mass Index (BMI)
- Blood pressure
- Diabetes control
They also recorded how many coaching sessions each participant attended.
Key Findings
| Time Point | Weight Loss (kg) | BMI Change | HbA1c Change* |
|---|---|---|---|
| 3 months | ~1.0 kg | –0.35 units | — |
| 6 months | 1.07 kg* | –0.35 units | –0.55 percentage points |
*Statistically significant
- After three months, participants lost an average of almost one kilogram.
- By six months, the loss increased to about 1.07 kilograms, a statistically significant change.
- BMI decreased by 0.35 units over the same period.
- For those with diabetes or prediabetes, average HbA1c dropped by 0.55 percentage points after six months—an important improvement.
Dose–Response Relationship
The more coaching visits patients attended, the greater their weight loss. This dose‑response pattern underscores the value of consistent engagement with a dietitian.
Implications
These results suggest that adding trained dietitians to primary care teams can help patients at risk for chronic conditions improve key health measures, potentially reducing future disease burden.
Data derived from a prospective cohort study involving routine clinical care.
