Nutrition guides for the conditions trackers leave out
Endometriosis, PCOS, adenomyosis, perimenopause, Hashimoto's: standard calorie trackers treat these as invisible. Each guide below gathers what health authorities and published research say about eating with that condition, and is honest about where the evidence runs out.
Your diagnosis changes everything about how you eat
Research on PCOS points at carbohydrate quality over quantity, because insulin resistance sits underneath most cases. Guidance on perimenopause raises calcium and vitamin D. For endometriosis and adenomyosis the honest answer is that the evidence is thin, and the guides say so rather than filling the gap with a protocol.
Standard calorie trackers engage with none of it. They give you one daily calorie target and a food diary, the same on every day of the month. Oli does not diagnose you or build a plan around a condition either. What it does is move that target with your cycle phase, which is the part every other tracker leaves flat.

What the app does, and what it doesn't
These guides are reading, not a setting. The app never asks for your diagnosis, stores it, or changes what it does because of it.
In the app you set calorie and macro targets, and if you track your cycle you set a separate profile for each of the four phases. The AI Target Coach can propose all four from a sentence about you, and you review and save them.
Oli reads your period data from Apple Health, works out which phase you are in, and your daily target glides between those profiles instead of jumping.
For anything condition-specific, the Ask coach answers with your phase, your logged meals and your remaining macros in hand. It returns general nutrition information, not a treatment plan.
A note on medical advice: these guides summarise published research and guidance from named health authorities. They are educational content, not medical advice, and Oli is not a medical provider. The app tracks calories, protein, carbohydrates, net carbs and fat. It does not track micronutrients or symptoms, and nothing in it is tailored to a diagnosis. Always work with your healthcare team for diagnosis and treatment decisions.
