Amber McKenzie 
Age: 32
Height: 5’5”
Total Weight Loss: 22 pounds*
Number of Challenges: 3
Location: Toronto, Ontario

Amber struggled with her relationship with food and yo-yo dieting for 20 years, which left her feeling ashamed. After meeting her fiancé and moving to a new city, she found Isagenix and decided to change her life. Amber committed to being happier and healthier and found her strength in the IsaBody community.

“I believe that my crazy past is what has guided me to this community,” she said. “It is this foundation that has kept me steady in my commitment to wellness.”




Brandon Bullert
Age: 41
Height: 5’11”
Total Weight Loss: 20
Number of Challenges: 1
Location: Oceanside, California

After calling off his engagement, Brandon, a former U.S. Marine Corp Sergeant and Master Trainer, felt lost and out of control. He became an emotional eater and felt unmotivated in all aspects of life. Brandon found his second chance when he was introduced to Isagenix.

“Isagenix has changed my life, not only transforming my body but also WHO I am,” he said. “I have found a sustainable lifestyle, community, business, and the love of my life.”




Colleen DeVeyrac
Age: 51
Height: 5’3”
Total Weight Gain: gained 8 pounds of lean muscle*
Number of Challenges: 10
Location: Kamloops, British Columbia

As a teacher and public speaker, Colleen spent her days teaching her students how to be healthy and handle stress, but she wasn’t following her own advice. At 48, she looked at her reflection and wanted to cry – feeling like a complete failure. Now, 10 IsaBody Challenges later, the 51-year-old sees something totally different when she looks in the mirror – a strong triathlete and future Ironman.

“Aging shouldn’t be scary,” she said. “It’s your chance to get rid of all the negative thinking and live the life you’ve always dreamed of.”




Julie Marchak
Age: 43
Height: 5’6”
Total Weight Loss: 144 pounds*
Number of Challenges: 7
Location: Victoria, British Columbia

Before Isagenix, Julie had the perfect excuse: Why bother trying to change her life, if deep down she knew she was going to fail? It was that attitude that kept her from being the incredible wife and mother she knew she could be. With the help of Isagenix nutrition, Julie finally put herself at the forefront of her life and has now lost half her body weight!*

“I needed this to work; my life depended on it,” she said. “The IsaBody Challenge has taught me that I can set goals and accomplish anything I set my mind to, because I am worth it.”




Mark Ostrowski
Age: 54
Height: 5’10”
Total Weight Loss: 100 pounds*
Number of Challenges: 7
Location: La Grange, Illinois

“Who can I help today?” This is the mantra that Mark has lived by from childhood to parenthood. He’s been a champion for everyone who has come into his life, from fellow students in college to victims of violent crimes as a prosecutor, as has dedicated his life to taking care of his wife and three kids. He would do anything for them if it meant they could reach all their dreams, but eventually, he realized he had lost sight of his own. In the last three years, Mark has completely transformed his life with Isagenix and the IsaBody Challenge.

“For the first time, I became a champion for me,” he said.

*​Results not typical. Weight loss, muscle gain, lifestyle, and other results depicted here reflect exceptional individual experiences of Isagenix Customers and should not be construed as typical or average. Results vary with individual effort, body composition, eating patterns, time, exercise, and other factors, such as genetic and physiological makeup. ​In a two-phase study performed from 2015-2016 by Skidmore College in New York, researchers evaluated use of Isagenix products for weight loss followed by weight maintenance. As part of the weight loss phase, the participants took part in a calorie-controlled regimen of Shake Days and one Cleanse Day per week and lost an average of 24 pounds after 12 weeks. During the weight maintenance phase, the subjects who continued the calorie-30 controlled program using Isagenix products better maintained their weight loss in comparison to those who transitioned to a traditional diet after 52 weeks.
