Impact of Dietetic Counseling Combined With Digital Tools on Obesity‐Related Indices in Greek Adults: The GATEKEEPER Study
Authors' conclusion
Dietetic counseling improved anthropometric and metabolic outcomes in adults at risk for MetS. Digital tools enhanced physical activity but did not provide additional short-term metabolic benefits.
Study context
- Population
- Adults aged ≥ 55 years with ≥ 1 metabolic syndrome (MetS) risk factor (high risk for metabolic syndrome), Greece954 analysed
- Participants

- Primary endpoint
- Change in waist circumference
- Follow-up
- 3 months
