Healthness counts all 18 for you.
Not just protein, carbs and fat. Micronutrients count from your meals and your supplement stack together, so you can see what your diet is actually missing.
Is Healthness medical advice? No. It is an educational tracking tool. Fasting is not right for everyone — if you are pregnant, diabetic, on medication, or have a history of disordered eating, talk to your doctor before changing how you eat.
