Looking for a Layne Norton calorie calculator?
If you follow Layne Norton (BioLayne) and want a daily calorie target, first estimate your maintenance calories, also called total daily energy expenditure (TDEE). Maintenance is your baseline: eat below it for weight loss, around it for maintenance, or above it for weight gain. Check that estimate against your actual intake and weight trend over the following weeks.
Layne Norton is the founder of BioLayne. His associated nutrition app is Carbon Diet Coach, designed by Norton and dietitian Keith Kraker to provide personalized nutrition targets and adjustments. This is an independent guide; MacroCodex is not affiliated with or endorsed by Layne Norton, BioLayne, or Carbon and does not use Carbon's coaching system.
Our claim: See measurable weight gain or weight loss results within 2–3 weeks of using MacroCodex. Many users start seeing results as early as the first week.

Calculate a daily calorie target for free
- Open MacroCodex and enter your details to get an initial maintenance-calorie estimate.
- Choose whether you want to maintain, lose, or gain weight. The app sets a daily calorie target from your maintenance estimate and goal.
- Record your calorie intake and body weight consistently. MacroCodex updates its maintenance estimate and targets as it learns from your trend.
Log what you actually ate, not just the target you intended to hit. An adaptive estimate needs your recorded intake and weight trend to interpret progress. If you exceed your target on a particular day, recording that intake is more useful than leaving the day blank or entering your planned calories.
MacroCodex is free and has no ads or subscription. It asks you to enter daily calorie totals; for a food diary, you can use a separate logger such as CalorieCodex. Carbon combines food tracking and coaching in its own app; MacroCodex's daily-total workflow is different.
