Lifestyle: what the evidence supports, and what it does not

Including how to recognise the claims that are being sold to you.

Lesson 4 of 5

12 min Text

What this lesson says

  • Where studies show benefit it is generally from a modest, sustained change rather than a dramatic one
  • The improvements reported are in specific measures — ovulation, glucose handling — not in the condition disappearing
  • PCOS also occurs in women who are not overweight, and the same assessment applies
  • No diet, supplement or programme cures or reverses PCOS
  • The ICMR's National Institute of Nutrition publishes dietary guidance written for Indian households

This is general education. It is not advice about your own situation, and it does not replace seeing a clinician.

Written lesson.
  1. 1. For women with PCOS who are above a healthy weight, a modest and sustained change does improve some things for some people. That is a real finding and worth having. It is also narrower than the way it is usually reported to you.
  2. 2. Two qualifications carry most of the weight. The benefit in studies generally comes from a modest reduction sustained over time rather than a dramatic one. And what improves is specific — measures like ovulation and glucose handling — rather than the condition going away.
  3. 3. Nobody can promise you regular cycles from a weight change, and anybody who does is selling something.
  4. 4. PCOS also occurs in women who are not overweight. For them, the same condition needs the same assessment and the same discussion of goals, and being told to lose weight when there is no weight to lose is a dead end some women are handed for years.
  5. 5. On what to eat: nothing about this requires an imported diet, an expensive programme or a supplement. The ICMR's National Institute of Nutrition publishes dietary guidance written for Indian households and Indian food, which is a more useful starting point than anything sold alongside a PCOS claim. Be particularly careful with products marketed as reversing PCOS or curing insulin resistance naturally — those claims are not supported and some of them interact with prescribed medicines.
  6. 6. One last thing that belongs in a lesson about lifestyle. Weight, cycles, mood and appetite influence each other in both directions, and being told repeatedly to lose weight is itself hard on people. If that is where you are, it is worth saying to a clinician rather than absorbing.
