Eating well, tracking macros, exercising, and trying to sleep more should help. But if your body still is not responding, effort may not be the missing piece.
For many women over 35, hormone shifts, insulin resistance, cortisol patterns, thyroid-related changes, poor recovery, digestion, inflammation, and perimenopause can all influence how the body responds.
That is where generic advice falls short. You need context, not more blame.
