Part of the Loopa iOS app guide.
Health Info & Sources lists where Loopa's numbers come from: the equations behind your calorie and protein targets, the guidance behind your macros, and the food and supplement databases. It is part of Loopa Basic and Loopa Premium.
Where to find it
- Health tab › My Loopa › Health Info & Sources. You can also search the Health tab for it.
- You tab › About › Health Info & Sources.
- Any Sources button (an ⓘ, read by VoiceOver as "Sources and medical disclaimer"). It sits beside your targets on Today's Page, in Health Settings and on the plan you see at the end of setup, on the Weekly report (the summary, Energy Balance and Macros cards), in the What-If simulator, and at the foot of Loopa AI Coach. A Sources button opens the same list as a sheet titled Sources; tap Done to close it.
Not Medical Advice
The list opens under Not Medical Advice: "Your targets (calories, BMR/TDEE, protein, carbs and fat) are estimates from published equations and public-health guidance. They're a starting point, not a prescription, and they're general wellness information, not medical advice. Talk to your doctor or a registered dietitian before making changes, especially if you have a medical condition, are pregnant or nursing, or take medication."

Food & nutrition database
