Ann Sirenko is a Registered Holistic Nutritionist and Hormone + Weight Loss Specialist who supports women navigating perimenopause, hormone shifts, stubborn weight gain, low energy, poor sleep, cravings, and inflammation. Her approach moves beyond calorie-focused dieting and instead focuses on restoring metabolic health, promoting hormone balance, and reducing internal stress on the body for lasting change. Her work is rooted in functional nutrition and guided by data — including comprehensive blood work — to uncover root causes of metabolic imbalances rather than guessing.

Ann’s passion for this work is also personal. After experiencing years of dismissed symptoms — including brain fog, fatigue, digestive distress, and autoimmune-thyroid challenges — she understands how discouraging it can be to feel unheard or stuck without answers. That experience informs her empathetic, supportive coaching style while keeping the focus firmly on results.

She graduated from the Canadian School of Natural Nutrition in 2017 and brings both clinical training and real-world experience to her practice. Ann is known for translating complex lab data and physiology into clear, practical nutrition strategies that feel doable and sustainable in everyday life.

Clients often describe feeling lighter, more confident, balanced, and more connected to their bodies within weeks of working together — with renewed energy, improved digestion, and a clear path forward.

Ann offers personalized nutrition plans rooted in science and guided by blood work for women who want sustainable weight loss, balanced hormones, and improved energy — without extreme restriction or one-size-fits-all plans.

Her work begins with a comprehensive assessment of each client’s health history, symptoms, lifestyle, and metabolic patterns. Each individualized plan is informed by comprehensive blood lab results (30+ markers) to identify underlying contributors such as blood sugar imbalance, inflammation, nutrient deficiencies, and thyroid or liver stress — all common during perimenopause. This data-driven approach allows for precision rather than guesswork when it comes to which foods to eat and how much to eat to achieve goals.

Clients are guided through a structured, phased nutrition plan tailored to their physiology, preferences, and real-life demands. The focus is on stabilizing blood sugar, supporting hormone balance, restoring metabolic rhythm, and reducing internal stress — all while ensuring clients feel nourished, satisfied, and supported.

Ongoing coaching and accountability are a core part of Ann’s practice. Clients receive education, regular check-ins, and adjustments as their bodies respond, allowing the plan to evolve with them. Ann emphasizes clarity and empowerment, helping clients understand why their body is responding the way it is and how to maintain results long-term.

Ann works virtually with clients and supports women who are ready to move away from dieting and toward a more informed, sustainable approach to health and weight loss.
