Frequently Asked Questions
How accurate is a macro calculator?
Macro calculators provide a solid starting estimate based on validated scientific formulas. However, individual metabolism varies by 5-15%. We recommend using the results as a starting point and adjusting based on your progress over 2-3 weeks.
Should I eat the same macros on rest days?
For most people, keeping macros consistent is simplest and most effective. Advanced athletes may benefit from cycling carbohydrates (higher on training days, lower on rest days), but this adds complexity without significant benefit for beginners.
What is the best macro ratio for fat loss?
Research consistently shows that higher protein intake (1.6-2.2g per kg body weight) is the most important factor for preserving muscle during a caloric deficit. Our calculator sets protein at 35% of calories during fat loss, which typically falls within this range.
How do I track my macros?
The most effective method is logging your food intake using an app like FitHelp, which includes a nutrition tracker with a food database, barcode scanner, and daily macro targets. Consistency in tracking is more important than perfection.
