Scientific title
Body and future health: a single centre, single blind, four arm, randomised controlled study
Acronym
Study hypothesis
Body fat percentage and metabolic and mental stress can be reduced using a mini-intervention which includes diet and physical activity guidelines and which the participants can carry out using web-based guidelines and with minimal help from specialists. These effects are stronger when the participants use additional web-based exercise coaching program to increase physical activity and improve fitness, or when the participants use additional whey protein drinks.
Ethics approval
The study was approved by the Ethics Committee of the Central Finland Health Care District on 18th February 2011 (Dnro 3U/2011)

Primary outcome measure
1. Fat percentage measured by Dual Energy X-Ray Absorptiometry (DEXA) at baseline, at 3 and at 6 months follow-up
2. Daily stress level measured by heart rate monitor (based on heart rate variability and determined differently for day and night).
Secondary outcome measures
1. Changes in cardio-metabolic risk factors
2. Changes in diet, physical activity and sleep
Measured from baseline to 6 months follow up.
All questionnaires (including readiness to change, self-efficacy, and acceptance and action questionnaires) and other variables are also analysed to find out which factors predict best adherence and responses to the interventions.
