What do these numbers mean?
+
+ -
+ BMR — The calories your body burns at complete rest just to keep
+ you alive (breathing, circulation, cell production).
+
+ -
+ TDEE — Your total calories burned per day including physical
+ activity. Eat this amount to maintain weight.
+
+ -
+ Weight Loss — A 500 cal/day deficit leads to ~0.45 kg (1 lb)
+ lost per week.
+
+ -
+ Weight Gain — A 500 cal/day surplus leads to ~0.45 kg (1 lb)
+ gained per week.
+
+
+
+ * Calculated using the Mifflin-St Jeor Equation, considered the most accurate BMR
+ formula.
