Gardening with Green Gym and Meat Free Monday is an innovative intervention designed as part of the EU-INHERIT consortium implemented in a primary school in Greater London in collaboration with the Conservation Volunteers [TCV, the organisation who runs Green Gyms (GG)] and Meat free Monday campaign, UK (MFM). The project aims at improving children’s health behaviour (physical activity, PA and diet) and mental well-being in short term and tackle overweight and obesity in longer term.  The implementation of the pilot intended gardening in the school grounds operated by the TCV, engaging children and teachers in the process, and linking the gardening with the curriculum and with the school meals. Gardening activities in the school grounds included clearing the weeds, preparing the garden beds, clearing the path, making a fence, sowing seeds, learning to use gardening equipment, preparing the path to the greenhouse and other activities.
