Design outcomes

Primary

Measure	Time frame
Weight loss is determined by measuring weight (kg) and waist circumference (cm) at baseline, 6 and 12 months.	—

Secondary

Measure	Time frame
1. Physical activity is measured using the International Physical Activity Questionnaire (IPAQ-short) during session one and one week before follow up at six months 2. Diet is measured using the Food Frequency Questionnaire during session one and one week before follow-up at six months 3. Use of goal imagery is measured using the Thought Frequency Scale at home baseline, one week before session one and the first booster call at the end of trial week four 4. Quality of Life is measured using the QoLIAD (Global Quality of Life Assessment) during session one and one week before follow-up at six months 5. Treatment expectancy/credibility is measured using Credibility/Expectancy Questionnaire after the second session at the end of week two 6. Self-efficacy for exercise is measured using Exercice Self-Efficacy Scale (SCI) one week before session one (lab baseline) at home baseline and at the end of week four after the first booster call 7. Participant experience is measured using the participant experience questionnaire at follow-up 8. Self-efficacy for diet is measured using WELQ (Weight Efficacy Lifestyle Questionnaire)	—
