Depending on the feature, this may include a meal photo or description, your question, and relevant profile, weight, body-fat, or calorie summaries. Progress photos are not included in AI body trend reviews. AI estimates can be inaccurate and should be reviewed before saving. Nutrition targets are planning estimates, not medical prescriptions. LightYet is not a medical device and does not replace professional medical advice.
