Body Composition, Nutritional and Cardiovascular Status and Lifestyle Factors of Adults Who Are on Plant-Based Diet

Plain-language summary

There is an objective lack of data on the body composition, nutritional status, cardiovascular status and lifestyle of adults on a plant-based diet (PBD). The aim in this cross-sectional study investigators will document the differences in the body composition, nutritional intake and general health status of healthy adults aged 18 to 80 years who are on plant-based diet of 0.5-10 years and to determine if their body composition status is associated to the duration of eating with PBD between the 3 groups: those that are 0.5-2 years (short-term), 2-5 years (medium-term) and 5-10 years (long-term) on PBD. This study will also include the monitoring of other factors of healthy and active lifestyle of PBD participants, namely the status of habitual and organized physical activity, the status of daily long-term seating, the status of stress and hygiene of sleep, socio-economic status and the motive(s)/reasons for starting PBD. Investigators will also record their maximum (lifetime) body weight, body weight upon entering the PBD lifestyle, and using data from participants, blood analysis to collect their basic biochemistry results, and data on current blood pressure status. The investigators hypothesis is that: (H1): There are no differences in nutritional status between people who are short- (0.5-2 years), the medium- (2-5 years) or the long-term (5-10 years) on PBD. (H2): At least 80% of the tested subjects have plasma lipid values and blood pressure within the reference values. (H3): There is difference in lipid profile and body composition between people who are short- and the medium but not between medium and long-term PBD.
