TDEE · Low-GI macros · Indian meal plan · PMOS correction

For adult women with confirmed or suspected PMOS (Polyendocrine Metabolic Ovarian Syndrome, formerly PCOS). Educational tool only — not a substitute for dietitian or gynaecologist advice. Women with disordered eating, pregnancy, or severe comorbidities should seek direct clinical support.
Age, Height & Weight * REE computed via Mifflin–St Jeor. BMI auto-calculated to set evidence-aligned deficit targets (Int'l PMOS Guidelines 2023).
Physical Activity Level * PAL multiplier on REE → TDEE. PMOS guidelines recommend ≥150 min/week moderate + 2 days resistance. ≥250 min/week for significant weight loss.
Nutrition Goal * Int'l PMOS Guidelines (2023): 5–10% weight loss over ~6 months produces clinically meaningful improvement in metabolic, reproductive and psychological outcomes.
Insulin Resistance / Glucose Status * Sets default macro template. Low-GI high-fibre pattern improves insulin sensitivity, menstrual regularity and ovulation in IR-positive PMOS (Moran et al. 2013).
Macro Template * No single macro ratio is mandated by PMOS guidelines — adherence and energy balance are central (Teede 2023). All templates produce equivalent metabolic outcomes when calories match.
Dietary Preference * Filters Indian meal suggestions. Macro targets are identical — only the food sources change.
Reproductive Goal * Drives safety messaging. Pregnancy: deficit removed, focus on diet quality and GDM screening. Aggressive deficits contraindicated in pregnancy.
PMOS Metabolic Correction EXPERIMENTAL 2025 meta-analysis (Thomas et al., 13 studies): mean REE difference PMOS vs controls = ~30 kcal/day — not physiologically meaningful. No guideline endorses this correction. Enable only if a clinician has confirmed unusually low REE.

This calculator is an educational and clinical-support tool for Polyendocrine Metabolic Ovarian Syndrome (PMOS, formerly PCOS), aligned with International Guidelines (2023) where evidence exists. Many dietary recommendations are based on low-to-moderate quality evidence. This tool does not replace individualised care from a registered dietitian, gynaecologist, or endocrinologist. Women with disordered eating, pregnancy, significant comorbidities, or severe obesity must seek direct clinical supervision before following any energy prescription.
