In the trial program, fathers and children significantly improved their overall health and quality of life.


  • reduced their waist circumference
  • reduced their blood pressure and resting heart rate
  • increased their rates of physical activity
  • decreased their kilojoule intake
  • improved their overall diet

Importantly, fathers maintained improvements from 3- to 6-months after the program, despite no contact between researchers and participants.

Fig. 1 – Fathers in the HDHK program lost more weight than those who did not receive the program (control group) and weight loss was sustained longer term (3 months and 6 months).

85% of participants lost greater than 5% of their body weight
