A woman does a program exactly as instructed and loses less than the man who started beside her. She concludes she is doing something wrong. Frequently she isn't — she is working against a hormonal backdrop nobody evaluated.
The Perimenopause and Menopause Shift
As estrogen declines, fat distribution changes. Storage moves from hips and thighs toward the abdomen, insulin sensitivity often worsens, and muscle becomes harder to maintain. Sleep frequently deteriorates at the same time, which affects cortisol and appetite regulation. A GLP-1 can still work well in this setting, but if the underlying hormonal change is untreated, it is working uphill.
PCOS and Insulin Resistance
PCOS is fundamentally intertwined with insulin resistance for many women. That makes weight loss harder in a way that is genuinely physiological, and it also means addressing insulin directly often produces disproportionate benefit — sometimes improving cycles and other symptoms alongside weight.
Thyroid: The Common Miss
Thyroid dysfunction is substantially more common in women, and it is regularly overlooked when a single TSH lands inside a wide reference range. If the thyroid is underperforming, weight loss will be slower and harder regardless of what else is prescribed. As Dr. Allen's book, Why Do I Feel Like This? describes it, the thyroid is the general of the system — when it is not commanding well, everything downstream underperforms.
- Estrogen and progesteroneShape fat distribution, insulin sensitivity, sleep and mood.
- ThyroidSets metabolic pace across the whole system.
- TestosteroneYes, in women too — relevant to lean mass, energy and libido.
- CortisolChronic elevation favors abdominal storage and drives appetite.
Muscle Matters More, Not Less
Women generally start with less lean mass and lose it more readily during rapid weight loss, particularly around and after menopause when bone density is also at stake. Protein and resistance training are not optional additions here. They are central.
