Frequently asked questions
Is Lunahealth free to use?
Yes, generating your plan is completely free. The site is supported by advertising.
Is my health data private?
The information you enter is used only to generate your plan. We do not sell your data. See our Privacy Policy for full details.
How accurate is the calorie estimate?
We use the Mifflin-St Jeor equation, the same formula used by most clinical dietitians as a starting point. Individual metabolism varies — treat the number as a starting range, not a precise prescription. Adjust up or down based on your real-world results over 2–3 weeks.
Is the lunar calendar scientifically proven?
The lunar phases are astronomically accurate. The wellness cues attached to each phase are based on traditional practices and emerging research (particularly around sleep and the full moon), but are not proven medical guidance. Use them as gentle prompts, not rules.
What does the horoscope sign add to my plan?
Your sign adds a one-line personality-based motivational note — something to help you choose movement styles and habits that suit your temperament. It is not medical advice and has no effect on your calorie or exercise calculations.
Can I use this if I have a medical condition?
Lunahealth provides general wellness suggestions only. If you have a medical condition, are pregnant, recovering from injury or surgery, or take regular medication, please consult your doctor or a registered health professional before following any plan from this site.
How do I update my plan?
Simply return to the home page and fill in the form again with your new data. Each submission creates a new plan. We recommend reassessing every 4–8 weeks or whenever your weight, activity level or goal changes significantly.
Why does my BMI say I am overweight but I feel healthy?
BMI is a screening tool with well-known limitations — it cannot distinguish between muscle and fat, and its thresholds were derived from limited populations. Use it as one data point among many. A doctor can give you a fuller picture with a physical exam and bloodwork.
What does the body shape field do?
Your reported body shape (apple, pear, rectangle, athletic, hourglass) helps us tailor the exercise focus of your plan — for example, prioritising cardio for apple shapes and upper-body resistance for pear shapes. You can leave it blank and we will work from your other inputs.
