Key finding
Mean weight loss 4.2 kg during intervention among responders; total weight loss in maintainers at 3 years was 6.54 kg, while non-maintainers returned to baseline (+0.21 kg)
This study followed adults at high risk of type 2 diabetes after a primary-care lifestyle programme in Poland. Among the 105 people with complete 3-year follow-up, many lost weight during the intervention and a smaller subgroup kept that weight off afterward. Because there was no concurrent control group in this analysis, the findings should be interpreted cautiously.

Study focus
This study followed adults at high risk of type 2 diabetes after a primary-care lifestyle programme in Poland. Among the 105 people with complete 3-year follow-up, many lost weight during the intervention and a smaller subgroup kept that weight off afterward. Because there was no concurrent control group in this analysis, the findings should be interpreted cautiously.
Diabetes prevention programmes often achieve short-term weight loss, but maintenance is much harder. This study suggests that continued dietary behavior change, especially reducing total fat intake, may help preserve weight loss after a primary-care lifestyle programme. These findings can inform programme design, although the lack of a control group means they should not be over-interpreted.
No parallel control group in the analyzed long-term cohort Only 105 participants had complete measurements across all three examinations Predictor analyses compare maintainers with non-maintainers within the intervention cohort Diet and physical activity changes were self-reported
↓ Mean weight loss during intervention among responders was 4.2 kg at 1 year
↓ Maintainers achieved total 3-year weight loss of 6.54 kg, while non-maintainers returned near baseline (+0.21 kg)
↓ Waist circumference fell more in maintainers (−5.26 cm) than in non-maintainers (−0.33 cm)
