Lifestyle Alteration

To investigate the effects of simple dietary management and diet combined with exercise capacity-targeted intelligent lifestyle management on improving metabolic indicators in patients with overweight/obesity and metabolic syndrome.

The goal of this study is to learn whether receiving personalized, digital lifestyle advice during colorectal cancer screening leeds to changes in lifestyle over a two-year follow-up period. Changes will be measured using a composite score including diet, alcohol consumption, physical activity, body mass index and smoking habits. The main questions it aims to answer are: * Do participants who receive short, personalized digital feedback on their lifestyle - either once or through repeated rounds -change their lifestyle during the two-year study period, compared to those who do not receive any feedback? * Does the inclusion of additional contact, such as telephone consultation with healthcare providers, result in further lifestyle changes? Researchers will compare three groups which receive digital feedback at different intensities and a control group which does not get any feedback to see if lifestyle changes differ between the groups. Participants in four different groups will fill in a digital diet and lifestyle questionnaire at the start of the study and 2-4 times after this during the following 2 years. * Participants in three of the groups will receive a short digital feedback report on their lifestyle related to health recommendations after each completion of the questionnaire. * One of these groups will also be offered to go through the feedback report together with a healthcare provider in a telephone call. * This group will also receive invitations to motivational webinars every half year during the 2-year study period. The topics in the webinars address cancer preventive lifestyle. A secondary goal of the study is to understand whether the invitation to fill in the diet and lifestyle questionnaire affects participation in colorectal cancer screening. Therefore, a fifth group of individuals invited to colorectal cancer screening but not to be invited to fill in the questionnaire will be included for extra comparison. Participation in colorectal cancer screening will be compared between this group and the four groups that are additionally invited to complete the questionnaire. Another secondary goal is to learn which groups in the society consent to the current study. Therefore, sociodemographic characteristics will be compared between the invited individuals who consent and those who do not consent to the study.
