💜 PCOS Nutrition Calculator
Estimate calories, protein, fiber and hydration targets for PCOS-friendly weight management. This is general nutrition guidance, not medical diagnosis.
What this PCOS diet calculator does
This PCOS diet calculator for weight loss gives a practical starting point for your daily calories, protein, fiber and water targets. You enter your age, weight, height, activity level and goal, and it estimates numbers you can actually use to plan PCOS-friendly meals. It is designed for women who want PCOS-friendly weight loss, maintenance or lean muscle support while keeping food realistic and sustainable. It is a nutrition education tool, not a diagnosis: it does not test for PCOS and does not replace a doctor or dietitian.
How the calorie target is estimated
The calculator estimates your resting energy needs from your age, weight and height, then multiplies by an activity factor to approximate your daily maintenance calories. For a weight-loss goal it applies a modest reduction so the target supports gradual fat loss rather than an extreme cut, and it never drops below a sensible floor. For maintenance it stays near your estimated needs, and for a lean-muscle goal it adds a small surplus to support training. These are estimates to start from and adjust, not exact prescriptions.
Why PCOS weight management needs a practical approach
Very restrictive diets are hard to sustain and can backfire. A practical approach — a moderate calorie target, enough protein, fiber-rich carbs and regular movement — tends to be more realistic and easier to maintain over months. The aim of this tool is to give you steady, usable numbers rather than a crash plan, so progress feels manageable and food stays enjoyable.
Why protein and fiber matter
Including protein at each meal can support fullness and help maintain lean muscle while managing weight, which is why the calculator sets a protein target based on your body weight and goal. Fiber-rich carbs such as daal, chana, vegetables, oats, fruit and whole grains support meal quality and steadier energy, so the tool also suggests a daily fiber target. Choosing lower added-sugar options — fewer sugary drinks, sweets and refined-flour foods — helps keep calories in check without feeling deprived.
The PCOS-friendly plate method
A simple way to translate the numbers into meals is the plate method: fill roughly half your plate with vegetables and salad, a quarter with a protein source, and a quarter with a fiber-rich carb, adding a little healthy fat. This keeps meals balanced without weighing everything. South Asian meals fit this easily — for example, sabzi and salad with grilled chicken or daal and a plain roti or a portion of brown rice, with curd on the side.
South Asian and Pakistani / Indian meal examples
PCOS-friendly eating does not mean giving up familiar food. Practical swaps include daal or chana with vegetables and a controlled portion of roti or brown rice; eggs or chicken with sabzi and salad; curd or Greek yogurt as a protein-rich side; and paneer or tofu for vegetarian meals. Keeping deep-fried snacks, large glasses of juice and sugary desserts occasional rather than daily makes a meaningful difference over time.
Weight loss vs maintenance vs lean-muscle support
Choose the goal that matches where you are. A fat-loss target uses a gentle calorie reduction; maintenance keeps you near your estimated needs to hold steady; and a lean-muscle or strength goal adds a small surplus with higher protein to support training. You can move between goals as your situation changes — for example, cutting gently for a period, then maintaining to consolidate.
Using the result with the meal planner
Once you have your targets, the Meal Planner helps you turn them into actual meals, and the Calorie Deficit Calculator and Protein Calculator let you cross-check your numbers. Adjust meals without extreme dieting: shift portions, swap refined carbs for fiber-rich ones, and add protein rather than slashing calories. Strength training and daily walking may support weight management alongside nutrition.
What this calculator cannot do
This tool cannot diagnose PCOS, confirm insulin resistance, or account for individual medical conditions and medications. It gives general targets, not a personalised medical plan. Safety note: PCOS symptoms, irregular periods, diabetes concerns, fertility concerns, medication use, pregnancy or severe symptoms should be reviewed with a qualified healthcare professional. It does not promise a cure, reversal or guaranteed results.
Practical examples
PCOS fat loss
A moderately active woman aiming to lose weight might see a gentle calorie reduction with a higher protein target — enough to support fat loss without an extreme cut, built around protein, vegetables and fiber-rich carbs.
Maintenance
Someone happy at her current weight can use the maintenance goal to hold steady, keeping balanced meals and protein at each meal while focusing on consistency rather than restriction.
Active woman with strength training
A woman lifting weights a few times a week may choose the lean-muscle goal for a small surplus and higher protein to support training and recovery.

PCOS Diet Calculator FAQs
It is an educational tool that estimates daily calories, protein, fiber and water targets from your details, giving a PCOS-friendly starting point. It does not diagnose PCOS or replace a doctor or dietitian.
It can give a realistic calorie and protein target to support gradual weight management, but the calculator does not cause weight loss. Consistency over time is what matters.
Including protein at each meal supports fullness and lean muscle. The tool estimates roughly 1.6–1.8 g per kg of body weight depending on your goal, adjustable with professional advice.
No. Fiber-rich, less-processed carbs like daal, chana, vegetables, oats and whole grains support meal quality. The focus is on type and portion rather than cutting carbs out.
Lean protein, plenty of vegetables, lentils and beans, fiber-rich whole grains and nuts or seeds. Limiting sugary drinks, sweets, refined flour and deep-fried foods is often suggested.
Reducing added sugar and sugary drinks is a common practical step, but it is general guidance, not a strict ban. Individual needs vary, so personalised advice is best.
Regular activity such as strength training and daily walking may support weight management and wellbeing. It works alongside balanced nutrition rather than replacing it.
No. It provides general nutrition education only, does not diagnose PCOS, and does not replace a qualified healthcare professional for symptoms, fertility, diabetes or medication concerns.
PCOS diet calculator
This page keeps the familiar PCOS keyword for search and education, but uses PCOS as the newer public naming. The goal is practical nutrition guidance for calories, protein, fiber, hydration and meal focus.
Protein focus
Protein at each meal can support satiety and lean-mass maintenance.
Fiber focus
Fiber-rich foods like daal, chana, vegetables, oats, fruit and seeds can support better meal quality.
Steady meals
Balanced meals with controlled portions are usually more sustainable than extreme dieting.
