Karthika Thirugnanam, RD


I have been a clinical dietitian for about 5 years. I began my career working with advanced stage cancer patients in the public sector. In 2018, I began working at Tucker Medical where I began using low carb principles to help patients resolve & reverse metabolic ailments to improve their overall oncology outcomes. I also help patients who receive active cancer treatment implement TCR & TFR to reduce side effects and optimize benefits. My favourite tools for nutrition education are the low carb visual guides available through the Diet Doctor website!
