Multicomponent lifestyle interventions (diet, exercise, and behavioral strategies) are effective for reducing weight, central obesity, and insulin resistance in women with PCOS, with benefits observed even with modest weight loss (5-10%).

Start with a multicomponent approach: combine a modest calorie deficit (500-750 kcal/day) with regular physical activity (150+ minutes/week) and behavioral tracking (e.g., food/exercise logs). Aim for a 5-10% weight loss over 6 months if you have excess weight, but focus on healthy habits regardless of the scale number. Seek support from a dietitian or health psychologist to manage psychological barriers and improve adherence.

Lifestyle intervention (preferably multicomponent including diet, exercise and behavioural strategies) should be recommended in all those with PCOS and excess weight, for reductions in weight, central obesity and insulin resistance.

Why this rating

The guideline assigns 'Low' quality of evidence (QOE) due to methodological weaknesses and inconsistencies in the underlying RCTs, despite the recommendation being strong.
