We are using a short messaging service (SMS) programme in our study as a tool to provide healthy lifestyle advice and an aid to motivation.  The SMS acceptability questionnaires are evaluated in all follow-up visits.  Secondary outcomes are the changes in body weight, body mass index, waist circumference, blood pressure, fasting plasma glucose; lipids; proportion of participants achieving HbA1c ≤6.0%; HOMA-IR; HOMA-β; acceptability of SMS; dietary parameters; physical activity and quality of life.
