This calculator is suitable for most healthy adults who want a practical estimate for managing body composition, performance, or general nutrition. However, it is not a substitute for individualized medical or dietetic advice. People who are pregnant, breastfeeding, under 18, managing an eating disorder, or living with a medical condition that affects nutrition or metabolism should seek guidance from a qualified healthcare professional before following calculated targets.

That’s completely normal. You do not need to be perfect every day to make progress. What matters most is consistency over time. Try to stay reasonably close to your calorie and protein targets, and view your intake across the week rather than stressing over a single day. If one day is slightly off, just return to your plan at the next meal or the next day.

Yes. Your macro targets should match your current goal, whether that is fat loss, maintenance, muscle gain, or recomp. If your goal changes, simply recalculate your macros using your updated target. For example, someone finishing a fat loss phase may later switch to maintenance or muscle gain, and their calorie, protein, carb, and fat targets should be adjusted accordingly.
