Meet the Dietitians

“I read all of your bios and it was super refreshing to see that you don’t count calories or macros at all!”

– Brittany Jones Nutrition Group Client
Brittany L Jones, MS, RD, LD – CEO & Registered Dietitian

Hi! I’m Brittany – a Registered Dietitian, mom, wife, foodie, and owner of Brittany Jones Nutrition Group. I’ve been working with clients for over 10 years in Greenville, SC – and my biggest takeaway from my career thus far is that restricting anything (carbs/fat/time) and/or counting anything (macros/calories) doesn’t work in the long term. My philosophy has always been one where all foods fit in a healthy lifestyle. I am not about rules, or seeing things as strictly black, or white. I am about finding the shades of grey and living there. I can’t wait to meet you! Read more about Brittany here.
