How do you plan meals for a client with PCOS?
In short: The 2023 International Evidence-based Guideline for PCOS found no evidence that any one type of diet is superior to another. Focus on a sustainable healthy eating pattern tailored to the client's preferences and goals rather than an unnecessarily restrictive 'PCOS diet'.
For clients with higher weight, weight management can provide important clinical benefits, while healthy lifestyle changes also provide benefits without weight loss.
Psychological wellbeing and disordered eating should also be considered when planning nutrition support.

What the guideline actually says
The 2023 International Evidence-based Guideline for the Assessment and Management of PCOS, led by Monash University and endorsed by societies worldwide, is the reference most practitioners work from. On diet, its message is modest and worth taking at face value.
- No one dietary composition has been shown to be superior for anthropometric, metabolic, hormonal, reproductive or psychological outcomes in PCOS. The guideline recommends sustainable healthy eating consistent with general population guidance and tailored to individual preferences and goals.
- Weight management can help where appropriate. For clients with higher weight, weight management can be associated with significant clinical improvements. Where weight loss is an agreed goal, the guideline recommends an individualised energy deficit based on energy requirements, body weight and physical activity rather than prescribing one standard deficit for everyone.
- Healthy lifestyle helps at any weight. The guideline is explicit that the benefits do not depend on the scales moving, and it asks practitioners to be aware of weight stigma.
- Avoid unnecessarily restrictive or unbalanced diets.
You may also see a new name. In 2026, a global consensus process established polyendocrine metabolic ovarian syndrome (PMOS) as the new name for polycystic ovary syndrome (PCOS). The change removes the misleading reference to ovarian 'cysts' and better reflects the condition's endocrine, metabolic and ovarian features. A global transition to the new terminology is underway, so clients and practitioners are likely to encounter both PMOS and PCOS for some time.
Plan around the client, not the label
Because no one diet wins, start from what matters to this client: their bloods, their goals and how they like to eat. PCOS looks very different from one person to the next.
| If the priority is | Focus the plan on |
|---|---|
| Weight | An energy deficit they can hold for months, protein at each meal, and foods they already enjoy |
| Insulin resistance / metabolic health | Emphasise carbohydrate quality with fibre-rich foods such as whole grains, legumes, vegetables and fruit. Lower-GI choices can be useful where appropriate, while the overall dietary pattern and sustainability remain the priority. |
| Blood lipids | Unsaturated fats in place of saturated, oily fish, nuts and more fibre |
| Fertility | Overall diet quality and appropriate preconception folic acid supplementation according to relevant clinical guidance. |
| Energy and mood | Regular meals, enough carbohydrate for activity, and no crash diets |
Much of this reflects the same principles used in general evidence-based nutrition. Rather than needing a special 'PCOS diet', the eating pattern can be adapted to the client's individual metabolic health, reproductive goals, preferences and circumstances.
What to be wary of
- Blanket dairy-free or gluten-free rules. They're common on social media, but there's no good evidence that people with PCOS need to cut either without a separate reason, such as coeliac disease.
- Inositol. The guideline says inositol can be considered based on individual preferences and values, but clinical benefits appear limited and the evidence is not strong enough to recommend a specific type, dose or combination. Discuss the uncertainty, supplement quality and the client's goals rather than presenting it as a proven PCOS treatment.
- Medication considerations. Metformin commonly causes gastrointestinal side effects and long-term use may be associated with low vitamin B12 levels, particularly in people with additional risk factors. Medication side effects and B12 monitoring should be discussed with the prescribing clinician where relevant. For clients taking a GLP-1 medication, see what a meal plan should look like on a GLP-1.
- Highly restrictive diets. The guideline recommends avoiding unduly restrictive and nutritionally unbalanced eating patterns. Consider nutritional adequacy, sustainability, the client's preferences and any history of disordered eating when choosing an approach.
Eating, mood and body image
Depression and anxiety are more common in people with PCOS, and the guideline recommends screening for these. Eating disorders, disordered eating and body-image distress also require particular consideration, especially when discussing lifestyle or weight management. Ask about dieting history and eating behaviours before prescribing an energy deficit, and refer for appropriate psychological or eating-disorder support where needed.
Measure success beyond body weight. Depending on the client's goals and clinical picture, relevant outcomes might include metabolic markers, central adiposity, menstrual or reproductive outcomes, quality of life, energy and the client's relationship with food.
How to do it in Foodzilla
Foodzilla has a PCOS label for the meal plan generator, a ready-made PCOS plan to adapt, and forms to collect the medical and dieting history you need before you plan.
- 1Go to Forms & Bookings and stay on the Forms tab. Under Templates, press Use template on Health & Medical History, which covers conditions, medications and recent blood tests, and on Goals, Motivation & Readiness to Change, which asks what they have tried before. Press Save Form on each copy and send both before the first session.
- 2Open the client's Health & Diet Goals. Set the energy and macro targets on the Nutrition tab, then go to the Diet Preferences tab (Professional plan and above) and tick PCOS under Health & Allergies.
- 3Go to Meal Plans, choose the client and press Auto-Generate. PCOS is already selected under Dietary needs & ingredients. If lower-GI choices are appropriate for the client's goals, you can also add the Low GI filter. Both labels need the Professional plan or above, and every label you add narrows the recipes, because a recipe must carry all of them.
- 4Press Generate plan and review it in the Planner. To start from a finished week instead, choose New Plan, then Import From Template, and pick PCOS Plan 1800 kcal from the Templates Database. Treat its 1,800 kcal as a starting point, not the client's target.
- 5If a weight-neutral approach suits the client better, open their App Experience, turn off Calories and press Save Changes, so their app stops showing calories and kilojoules. You still see everything on their dashboard.
Good to know
- Use relevant clinical informationGlycaemic status and cardiovascular risk are important considerations in PCOS. Where results are available, use measures such as glucose testing and the lipid profile alongside the client's medical history, medications and goals to help individualise the plan. Vitamin B12 may also be relevant in clients taking metformin, particularly where additional risk factors for deficiency are present.
- Set goals beyond weightAgree at least one meaningful non-scale goal with the client, such as improving meal consistency, increasing fibre intake or another outcome relevant to their priorities. This gives you useful measures of progress beyond changes in body weight.
