The third weigh-in for the Lake Mary Healthy Living Magazine Challenge will happen this Saturday at the Lake Mary Farmer's Market.  

John McGivern and Emily Edwards have been following a healthy living lifestyle since last June when they were chosen as featured 'ambassadors' of the year-long program.

The two won the services of free training from Fusion Fitness in lake Mary as well as counseling, nutrition and medical services.

They are trying to reach a goal of losing over 100 pounds each and living a healthier lifestyle.

The ambassadors have enjoyed a large following on their blog and Facebook accounts.

People from across Central Florida have used John and Emily for inspiration and motivation.

The event will feature free low impact workout classes, 25 healthy living vendors, kids activities and fresh local produce at the farmers market.
