“Kelli Jennings helped my 28 year old son with a serious case of diverticulitis. She clarified all the confusing information we were finding ourselves about high fiber/low fiber and when to introduce them after the clear liquid phase ended.
Then she went above and beyond by educating us about different supplements to add to his diet to help rebuild his terrible gut after years of poor eating habits. She even provided helpful, reliable links for resources we needed. Kelli’s reliable advice and enthusiasm about diet turned his life around. He joined a gym and changed his eating habits so that he lost over 50 lbs an has kept it off for over a year now. We continue to be grateful for the incredible support, encouragement, and knowledge that Kelli gave our family.”

Kelli has helped me immensely throughout my athletic career from a young high school cross country and track athlete with an eating disorder to a professional mountain biker. After my first few weeks of working with Kelli on daily and performance nutrition for mountain bike racing I told my coach, “I feel AMAZING like I am doping or something!” Kelli is incredible at demystifying nutrition and making healthy daily and performance nutrition accessible to everyone with easy, practical habits and routines that relieve the stress around food without increasing time. I now also subscribe to her monthly dinner plans in which she provides recipes, grocery lists, and meal prep tips so that cooking healthy dinners takes no more than 30 minutes.
I am also a physical therapist and have referred many of my patients to Kelli as her knowledge of nutrition to support recovery and return to activity is extensive. I highly recommend Kelli for nutritional advice across the lifespan and activity levels.

Kelli helped me understand my lab results and gave incredibly knowledgeable feedback and recommendations that have helped me feel better every day especially when I exercise. I feel so much better after making some simple changes to my diet and supplements.

Kelli met with my teenage son and me about nutrition, specially for athletes. She was extremely knowledgeable about both sports nutrition and the unique needs of teen boys. Her resources were very helpful and empowered my son to take responsibility for his own meal planning, snack preparation, and hydration. She had great quick tips and practical ways to provide high protein, nutritious food without spending a fortune. Kelli followed up with us often and helped us revise the plan as needed especially when we dealt with other heath issues. I highly recommend Kelli!

Kelly is so amazing with sports nutrition advice. I have always been one to just wing it, but her advice has helped me understand what I need and when both during and after exercise.
Kelly even helped me a ton adtrr knee surgery with supplements to hhelp my body heal well. She explains things in a way I can understand and is so willing to share all her extensive knowledge.
