For many cancer survivors, food can become complicated. Something that once felt simple or joyful can turn into a source of stress, confusion, or fear. Treatment changes how foods taste, and side effects make eating unpredictable. Online advice can feel overwhelming or even frightening. That’s why having a trusted oncology nutrition expert in your corner can make such a powerful difference.
Survivor Fitness is grateful to partner with Chelsea Johnson, a registered dietitian nutritionist. As one of only 16 board-certified specialists in oncology nutrition in the state of Tennessee, Chelsea works with survivors across East Tennessee through her private practice, Chelsea Johnson Nutrition, LLC. Her passion, expertise, and compassion have helped dozens of participants rebuild their relationship with food and regain confidence in their bodies.
“I’ve been a registered dietitian nutritionist for almost eight years, with most of my experience in outpatient oncology,” Chelsea shared. “Nutrition is such a big part of how people feel during and after treatment, and yet it’s often one of the least supported areas.”
From Family Experience to Personal Vocation
Chelsea’s passion for this work is deeply personal. She first became interested in oncology nutrition after watching family members go through cancer treatment without proper nutrition support.
“We had no help regarding food choices,” she explained. “We could have really used an oncology dietitian to help manage symptoms, build strength, and encourage a positive relationship with food. That experience stayed with me.”
Today, she sees that same fear and uncertainty in many survivors who walk through her door. But she also sees what happens when people get the right guidance. “I love watching participants come in with fears around nutrition and leave with confidence,” she said. “Seeing them feel empowered is the greatest reward.”
Chelsea’s connection to Survivor Fitness began after meeting co-founder Meg Grunke at an event in Knoxville. “I could feel Meg’s passion for cancer survivors right away,” she said. “It was motivating, contagious, and it made me want to be part of what she was building.”
That connection carried through Chelsea’s work in outpatient oncology, where she began referring patients to Survivor Fitness as they completed treatment. Now, as an affiliate dietitian, she has worked with more than 75 Survivor Fitness participants, helping them set nutrition goals that fit into their daily lives.
“It has been so rewarding working with Survivor Fitness participants,” Chelsea said. “I see them build confidence with food choices, manage symptoms better, and explore new foods. When nutrition, movement, and mental health are all addressed together, lifestyle change becomes so much more impactful.”
When Nutrition Changes Everything
One story Chelsea often shares involves a participant who was on a daily oral chemotherapy drug that caused severe, ongoing diarrhea issues. The side effect was so disruptive that she became afraid to eat, dehydrated, and isolated. She was even considering stopping the medication that was helping treat her cancer.
Through a personalized nutrition plan that included specific prebiotics, probiotics, hydration support, and gentle meal adjustments, everything changed. “After just a few weeks, she was able to stop her diarrhea medication, add more fiber back in, and even cook a balanced meal to enjoy with her family,” Chelsea said. “Her smile that day was the biggest I’ve ever seen. Nutrition truly improved her quality of life.”
Making Sense of Nutrition Trends for Cancer Survivors
One of Chelsea’s biggest goals is to reduce fear around eating. “Not one single food caused your cancer,” she said. “Misinformation can lead survivors to feel guilty or afraid. That’s not helpful or accurate.”
She often reminds participants that simple, steady habits matter more than perfection. “Boring nutrition advice is usually the correct advice,” she said. “Eating whole foods, moving more, sleeping well, and managing stress have the biggest impact.”
Chelsea encourages survivors to think about what they can add to their plate instead of what they need to take away. Plants, in particular, play a powerful role. “Plants are packed with phytochemicals and fiber, which support gut health, heart health, immune function, and healthy cell growth,” she explained. “Choose real foods first. Fruits, vegetables, nuts, seeds, beans, and whole grains.”
Chelsea often hears questions about low-carbohydrate diets and high-protein trends. Instead of pushing strict rules, she takes a personalized approach. “A lot of survivors ask about cutting carbs because of fear or misinformation,” she said. “We talk about the science-backed strategies for life after cancer. Carbohydrates are our main fuel source. They support energy, strength, and focus.”
When it comes to protein, she works closely with participants to calculate what their bodies truly need and then find realistic ways to get there, especially for those dealing with taste changes or aversions after treatment.
Chelsea also integrates intuitive eating into her work with cancer survivors. “Healing the relationship with food makes everything else more sustainable,” she explained. “We focus on listening to the body and adding nourishing foods instead of restricting. That supports both the body and the mind.”
Supported Every Step of the Way
For anyone considering Survivor Fitness, Chelsea has simple advice. “Jump in. Don’t let fear hold you back. We meet you where you are, with no judgment and lots of encouragement.”
That spirit of care is what she loves most about the program. “Survivor Fitness does not give survivors mediocre resources,” she said. “The dietitians, trainers, and counselors are highly qualified and provide truly personalized care. That’s what every survivor deserves.”
With partners like Chelsea, Survivor Fitness continues to offer not just guidance but hope, confidence, and a path forward that feels supportive every step of the way.
