Weight Gain in Women
Root-Cause Naturopathic Care in Toronto
If you’re eating well, staying active, and still gaining weight — or unable to lose it — the issue is rarely willpower or calories alone. For many women, unexplained or stubborn weight gain is a symptom, not the problem itself.
As a Toronto-based naturopathic doctor, I help women uncover the root causes behind weight changes and restore metabolic balance using evidence-informed, natural medicine.
Why Weight Gain in Women Is Different
Women’s bodies are uniquely sensitive to hormonal shifts, stress, blood sugar changes, and life-stage transitions. Weight gain often appears during times of physiological change — even when lifestyle habits haven’t changed.
Weight gain may show up:
-
Around the abdomen, hips, or thighs
-
During perimenopause or after stopping hormonal birth control
-
After periods of chronic stress or burnout
-
Alongside fatigue, bloating, or mood changes
These patterns provide important clues about what’s happening internally.
Common Causes of Weight Gain in Women
Weight regulation is influenced by multiple systems working together. In clinical practice, I most often see weight gain linked to:
Hormone Imbalances
Estrogen, progesterone, cortisol, insulin, and thyroid hormones all influence fat storage, metabolism, and appetite regulation.
Blood Sugar & Insulin Dysregulation
Even without diabetes, insulin resistance can promote fat storage and make weight loss extremely difficult.
Chronic Stress & Cortisol
Ongoing stress can slow metabolism, increase cravings, and drive abdominal weight gain.
Thyroid Dysfunction
Suboptimal thyroid function can reduce metabolic rate, energy, and fat-burning capacity — even when TSH appears “normal.”
Gut Health & Inflammation
Digestive dysfunction, inflammation, and microbiome imbalances can disrupt hormone signaling and metabolic efficiency.
Nutrient Deficiencies
Deficiencies in key nutrients can impair mitochondrial function, energy production, and metabolic health.
How Weight Gain Is Assessed in Naturopathic Medicine
A meaningful evaluation looks beyond the scale. I use a comprehensive, individualized assessment to understand what’s driving weight changes.
This may include:
-
Detailed Symptom & Weight History
-
Hormone & Metabolic Blood Testing
-
Cortisol & Stress Response Testing
-
Thyroid Function Assessment Beyond TSH
-
Blood Sugar & Insulin Markers
-
Nutrient Status Evaluation
-
Inflammatory & Gut Health Markers
The goal is to identify why weight gain is happening — not just manage the outcome.
Naturopathic Approach to Healthy Weight Balance
Naturopathic care focuses on restoring the systems that regulate weight naturally, rather than relying on restrictive or unsustainable approaches.
Care may involve:
-
Nutrition strategies that support blood sugar and metabolism
-
Lifestyle interventions to reduce stress and improve sleep
-
Targeted supplementation to correct deficiencies
-
Gut and liver support to optimize hormone metabolism
-
Botanical medicine when appropriate
-
Individualized plans based on life stage and physiology
Weight balance is a byproduct of internal health — not punishment or deprivation.
No two bodies are alike.
The root cause of weight gain can look different for everyone and treatment plans are developed
based on each patient's unique needs.
FAQ
the 10 most common questions I get asked as a Naturopathic Doctor regarding weight gain
1 / Why can’t I lose weight despite eating well and exercising?
Weight loss resistance is a multifactorial system, and goes beyond diet and exercise alone. You always need to look at the other most important factors - your sleep, stress, and hormones. Weight loss resistance is often driven by hormone imbalances, insulin resistance, chronic stress, thyroid dysfunction, or inflammation — not calorie intake and exercise alone.
2 / Can hormone imbalances cause weight gain in women?
Weight changes are common during perimenopause due to shifting estrogen and progesterone levels, but persistent or rapid weight gain often signals underlying metabolic or hormonal imbalance.
3 / Can stress really cause weight gain?
Chronic stress raises cortisol levels, which can increase abdominal fat storage, cravings, blood sugar instability, and difficulty losing weight.
4 / Why does weight gain happen mostly around my stomach?
Abdominal weight gain is often linked to cortisol imbalance, insulin resistance, inflammation, or changes in estrogen metabolism.
5 / Can thyroid problems cause weight gain even if my TSH is normal?
Yes. Many women have suboptimal thyroid function despite “normal” TSH. Comprehensive thyroid testing can reveal conversion issues or autoimmune patterns affecting metabolism.
6 / Does gut health affect weight gain?
Yes. Gut inflammation, microbiome imbalances, and digestive dysfunction can impair hormone metabolism, increase inflammation, and interfere with healthy weight regulation.
7 / Why did I gain weight after stopping birth control?
Hormonal birth control can alter nutrient levels, insulin sensitivity, and hormone signaling. Weight changes after stopping may reflect underlying imbalances becoming unmasked.
8 / What testing do I need to look at the root cause of my weight gain?
You should always consider having your insulin, blood sugar, full thyroid hormone panel, cholesterol (lipids), liver function, nutrient deficiencies, reproductive hormones, and cortisol tested.
9 / How does a naturopathic doctor approach weight gain?
A naturopathic doctor looks for root causes using comprehensive testing and symptom analysis, then supports metabolic health through personalized nutrition, lifestyle, and natural therapies.
10 / When should I seek help for weight gain?
If weight gain is unexplained, rapid, or resistant to lifestyle changes — especially alongside fatigue, mood changes, or hormonal symptoms — deeper evaluation is warranted.
