Effects of Green-MED Diet Via the Gut-fat-brain Axis; DIRECT-PLUS
In Brief
A clinical study evaluating Physical activity, Physical activity+ MED diet, and 1 other intervention for Abdominal Obesity Metabolic Syndrome. Completed, enrolled 294 participants across 1 site.
Detailed Summary
Mediterranean (MED) diet, richer in plants/seeds (and dietary polyphenols) and low in processed meat (green-MED diet) may have a pronounced beneficial effect on age-related declines that begin in middle age, reflected by changes in adiposity, cognitive function, and cardiometabolic risk. The investigators hypothesize that long-term intake of this diet will significantly potentiate the effects of a healthy lifestyle (physical activity and Mediterranean diet), constituting a powerful strategy to halt or even reverse the progression of several age-related processes related to adiposity, cardiometabolic health and cognition. The investigators further hypothesize that lifestyle intervention might modify the gut microbiota profile and that autologous fecal microbiota supplement derived from the time of maximal weight loss might halt the expected subsequent regain phase.

Interventions
\*\*\*\*Sub-study from all 3 main arms: Autologous fecal microbiota supplement intervention derived from the time of maximal weight loss: At the 6-month time period, the time of anticipated greatest weight reduction, participants's feces samples will be processed to capsulized inocula. Samples will be frozen within 2 hours and will be kept at -80c pending analysis. Participants will be randomized to receive either research capsules or identical placebo capsules between 8 and 14 months time period. Placebo capsules will consist of a combination of powdered cocoa and vegetable gelatin in normal saline/glycerol and will be identical in appearance to research capsules.
