// Rule 01
Protein First, Always
Build every meal around your protein source. Once protein is hit, fill carbs and fats around it. This single habit prevents overeating and preserves muscle over 40.
// Rule 02
Water Before Coffee
16oz of water before your first coffee, every day. Most executive fatigue at 2pm is dehydration masquerading as an energy crash. Fix the water first.
// Rule 03
Never Arrive Hungry
Eat something before every important meeting, flight, or dinner event. Hungry decisions are bad decisions — for your diet and your business.

Frequently Asked Questions

Everything you need to know about macros and this calculator.

What is a macro calculator? +

A macro calculator determines your optimal daily intake of protein, carbohydrates, and fats based on your body stats and fitness goals. It uses the Mifflin-St Jeor equation — the most validated formula for calculating Total Daily Energy Expenditure (TDEE) — to give you a personalized calorie and macro target.

How many calories should a busy professional eat per day? +

It depends on your age, weight, height, sex, and activity level — which is exactly what this calculator accounts for. As a general benchmark, a moderately active professional in their 40s at around 180lbs typically needs 2,200–2,600 calories per day to maintain weight. Use the calculator above for your exact number.

How much protein do I need after 40? +

Adults over 40 should aim for 1.6–2.2g of protein per kilogram of bodyweight (about 0.7–1g per pound) to preserve and build muscle. After 40, muscle loss accelerates without adequate protein and resistance training — this calculator targets 2g/kg, which research supports as optimal for active adults in this age group.

What are macros and why do they matter? +

Macronutrients — protein, carbohydrates, and fats — are the three categories of nutrients your body uses for energy and function. Protein builds and repairs muscle. Carbohydrates are your primary energy source. Fats support hormones, brain function, and nutrient absorption. Tracking macros gives you more control than just counting calories, because the same calorie total from different macro splits produces very different body composition results.

How accurate is this macro calculator? +

This calculator uses the Mifflin-St Jeor equation, which research shows is the most accurate predictive equation for resting metabolic rate in most adults. Estimates typically fall within 10% of actual measured values. Treat your result as a strong starting point — track your results for 2–3 weeks and adjust up or down by 100–200 calories based on whether you're hitting your goal.

What's the easiest way to hit my macro targets as a busy professional? +

Focus on protein first — hit your daily protein target and let carbs and fats flex around it. Build every meal around a protein source (chicken, eggs, Greek yogurt, steak, salmon). Prep protein in bulk on Sunday. Keep protein bars and nuts accessible for travel. Download our free Executive Nutrition Cheat Sheet for a full guide built around real executive schedules.

Should I count macros or just calories? +

For busy professionals, tracking macros — especially protein — produces better body composition results than calories alone. You could eat 2,200 calories of pasta and chips or 2,200 calories of chicken, vegetables, and rice, and the body composition outcomes are dramatically different. If you're pressed for time, track protein only. Hitting your protein target consistently is the single highest-impact nutrition habit for people over 35.
