For women 40 and over

Midlife Metabolism

It’s not willpower. Your biology changed.

The diet that worked at 29 stops working at 45 — not because you stopped trying, but because the hormones that set your appetite, your sleep, and where you store fat have moved. This 2-minute quiz shows which of those patterns are most active for you right now.

Recognize what changed

Start with the signals you live with—not a generic meal plan.

  • Weight settles around your middle now, on the same routine that used to keep it off.
  • Sleep, cravings, digestion, and energy have all become less predictable at once.
  • You’re doing “the right things,” and the effort no longer matches the result.

These rarely arrive one at a time, because the hormones behind them work as a system. The quiz sorts your answers into the four patterns that drive most midlife weight change.

Map your pattern

Answer from your typical experience over the last few weeks.

Use the result well

Your report tells you where to start—not what you are.

  2. 02

    Change one thing, well

    Your report names a single first step. One change you actually keep beats four you abandon.

  3. 03

    Bring specifics to your doctor

    Two weeks of tracked symptoms turn “I’m tired and gaining weight” into something a clinician can act on.

Hormones are one input among several — sleep, stress, activity, medications, and medical conditions all shape midlife weight too. Twelve questions can point you at the most likely driver; they can’t see the whole picture.
