Meet Our Registered Dietitian Team
Helen Tieu, RD, MAN
Founder & Registered Dietitian
Helen is the founder of Diet Redefined, a Registered Dietitian who empowers busy professionals to lose weight in a sustainable way – without restricting food or their lifestyle.
After working with hundreds of high-achieving professionals, she began to notice the same pattern. They weren’t struggling because they lacked discipline. They struggled because their approach was cookie-cutter, restrictive, and simply didn’t fit their lifestyle. The more they restricted, the more it backfired in the long run.
Our goal is not to help you to lose weight for 6 months – and then regain it all back.
Our goal is to help you to lose weight for life. So you don’t just learn how to follow a meal plan. You understand how to make informed food choices in real life – while still being able to eat out, travel, enjoy carbs, and have a social life. All while progressing towards your weight loss goals and maintaining a healthy relationship with food.
Yes – you can have your cake, and eat it too (literally!)
If you’re tired of putting yourself last, and feel ready to invest in yourself to make lasting lifestyle changes – let’s connect.

Leeauna Duchesne, RD
Registered Dietitian | Sustainable Weight Loss & Gut Health
Leeauna is a Registered Dietitian who helps busy professionals take control of their weight, energy, and digestion – without the stress of restrictive diets. Whether your goal is sustainable weight loss, eating for fitness, or finally finding relief from digestive issues, she uses a practical, science-based approach to help clients get results that last.
Leeauna specializes in gut health and chronic disease management, including IBS, IBD (Crohn’s and ulcerative colitis), chronic constipation and diarrhea, acid reflux, fatty liver disease, and H. pylori. She also uses a functional nutrition lens to get to the root of symptoms – and create a clear path forward.
If you’ve ever felt frustrated with food sensitivities, bloating, or the never-ending “what’s for dinner?” cycle, she gets it – she’s helped hundreds of clients turn that around with personalized strategies that work in real life.
Leeauna has completed advanced training in Mastering Gut Healing: Effectively Applying the 5R Protocol, and collaborates with F45 gyms to support members in using nutrition to fuel performance, recovery, and long-term results.
When she’s not working with clients, you’ll find her cooking up new recipes, brainstorming meal ideas, getting in a workout at F45, or walking through nature with her dog Jack.
If you’re ready to feel confident, energized, and at ease in your body again – let’s connect!
