Safety & scientific sources

Before you begin

If you have food allergies, a medical condition, an injury, take medication, or have any other health or safety concern, consult a qualified medical professional before trying any diet, exercise or other guidance from Artex. This is especially important during pregnancy or breastfeeding, with a history of disordered eating, or when managing diabetes, kidney or heart disease.

Artex is an AI coach, not a doctor, registered dietitian or credentialed human trainer. Its suggestions and camera feedback can be wrong and do not replace individual clinical advice.

Calorie targets and individual needs

Astryx does not set daily calorie targets below 1,200 kcal for women or 1,500 kcal for men. These are app limits, not guarantees that these intakes are safe or sufficient for you. Your needs may be substantially higher; a clinician or registered dietitian can advise you.

Calorie expenditure, portions and macros are estimates. Do not eat less to meet a predicted date, skip necessary meals, dehydrate yourself or train through illness. Follow individualized medical guidance where it differs from an app suggestion.

Food allergies and exercise warning signs

Meal scans and fridge suggestions cannot reliably detect allergens, hidden ingredients or cross-contamination. Check packaging and ingredients yourself; do not rely on Artex to decide whether a food is safe for an allergy.

Stop exercising if you develop pain, dizziness or unusual shortness of breath. Seek urgent medical care for chest pain, fainting, severe breathing difficulty or signs of a serious allergic reaction. Camera form scores do not certify that a movement is safe.

Research behind the general principles

These sources explain general exercise and nutrition principles, not a validation of Astryx’s generated plans or target dates. Artex does not currently browse the web live during chats.

• World Health Organization — Guidelines on physical activity and sedentary behaviour (2020)

  For adults, recommends 150–300 minutes of moderate or 75–150 minutes of vigorous aerobic activity weekly, plus muscle-strengthening work on at least two days. Activity should be adapted to health and ability.

• Jäger et al. — ISSN position stand: protein and exercise (2017)

  Discusses roughly 1.4–2.0 g of protein per kg daily for most exercising individuals, with potentially higher needs during energy restriction. Astryx’s estimated targets are not a universal prescription; medical conditions can change protein needs.

• American College of Sports Medicine — Progression models in resistance training for healthy adults (2009)

  Explains progressive resistance training, workload, rest and adaptation to experience. These principles support gradual progression rather than simply adding fatigue.

• National Heart, Lung, and Blood Institute — Practical guide to overweight and obesity management (2000)

  Historical clinical guidance on individualized weight management, energy intake and professional supervision. It does not establish a safe intake for every person or guarantee a rate of change.

What a target date means

Progress depends on consistent training, appropriate nutrition and recovery, as well as individual response. A week count and calendar target are estimates, not promises of a particular physique or a measured success probability.
