This study aims to determine the effectiveness of nutrition therapy on weight loss and work effectiveness in obese vocational teachers. The research method used an experimental design with a one group pretest-posttest design. A total of 20 respondents participated in this study through a selection process using a purposive sampling method, and a pretest served as a control. The intervention in this study was conducted in 24 sessions, four times per week, with a calorie calculation of minus 25% of the total daily calories each day. The results showed that nutrition therapy intervention can reduce weight and improve work efficiency (p<0.05). The nutrition therapy group showed an average weight loss of 4.05 kg. In conclusion, nutrition therapy is an optimal strategy for improving teaching effectiveness.
