At the Root
Hormonal Weight Gain
Not the same as gaining weight from overeating. Usually a shift in how the body uses and stores energy.
Your Concerns
What Is It?
Hormonal weight gain is not the same as gaining weight from overeating. It usually reflects a shift in how the body uses and stores energy — driven by changes in insulin sensitivity, cortisol, thyroid function, and sex hormones. For many patients in their late 30s onwards, the changes accumulate quietly until the same diet and exercise routine stops producing the same outcome. At 23MD, hormonal weight gain is investigated through bloodwork and a clinical conversation before any plan is written.

What Could Be Causing It
Perimenopausal & Menopausal Shifts
Oestrogen decline changes fat distribution and insulin sensitivity.
Insulin Resistance
Body composition starts to favour fat storage over muscle synthesis.
Cortisol Dysregulation
Chronic stress alters where the body stores fat.
Thyroid Imbalance
Even subclinical hypothyroidism affects metabolic rate.
Sleep Architecture Changes
Disrupted sleep affects hunger hormones and recovery.
FAQs
Your Questions, Answered
The underlying mechanism is different. Hormonal weight gain reflects how the body is storing and using energy — not simply intake vs output. The same diet and exercise that worked at 30 may not work at 45, because the body is operating differently. The 23MD approach starts by investigating that difference.
No. Bio/bodyidentical hormone therapy is one tool, not the answer. For some patients, the consultation reveals that lifestyle, sleep, or metabolic optimisation will address the picture without hormone therapy at all. The right plan is the one that fits the bloodwork.
A typical weight-loss clinic focuses on the weight number. 23MD focuses on what is producing that number — which usually means looking at hormonal, metabolic, and lifestyle drivers together. The plan compounds across years rather than chasing a quick result.
Metabolic and hormonal interventions work on physiological timescales, not weeks. Most patients see meaningful change across 3–6 months, with longer-term compounding over 12–24. The 23MD approach is 'measured in decades' — one of the six pillars of the practice.
Some plans are time-limited; others continue across years. The honest answer is that it depends on what's driving the picture. The consultation will discuss this explicitly — knowing what you're committing to is part of how 23MD practises.
