Estrogen levels are inversely associated with adiposity in premenopausal women, with higher estradiol levels found in healthy-weight women compared to obese women, suggesting a role for estrogens in restraining adipose tissue accumulation.
For premenopausal women, maintaining healthy weight may be biologically easier due to protective estrogen effects, but this protection diminishes after menopause. Focus on maintaining healthy weight before menopause to mitigate the inevitable fat gain associated with estrogen loss.
GoodSupportsHIGH confidence
Age-corrected early-follicular estradiol levels were 40 pg/ml in healthy-weight women versus 33 pg/ml in obese women, with no overlap in 95% confidence intervals (95% CI) (Freeman et al., 2010).
Why this rating
Based on a systematic review of clinical and pre-clinical literature, including specific human studies with non-overlapping confidence intervals.
