Formula Used

BMR (Mifflin-St Jeor) = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + S
TDEE = BMR × Activity Multiplier
Target Calories = TDEE × Goal Multiplier

Where:

BMR = Basal Metabolic Rate (calories burned at rest)
S = Gender constant (+5 for males, -161 for females)
TDEE = Total Daily Energy Expenditure
Activity Multiplier = 1.2 (sedentary) to 2.5 (extremely active)
Goal Multiplier = 0.8 (fat loss) to 1.15 (muscle gain)

Example Calculation

Real-World Scenario:

A 30-year-old male who is 5'10" (178 cm) and weighs 175 lbs (79.4 kg) with a moderately active lifestyle who wants to lose fat.

Given:

Age = 30 years
Gender = Male
Height = 178 cm
Weight = 79.4 kg
Activity Level = Moderately Active (multiplier = 1.55)
Goal = Fat Loss (multiplier = 0.8)

Calculation:

BMR = (10 × 79.4) + (6.25 × 178) - (5 × 30) + 5 = 794 + 1112.5 - 150 + 5 = 1761.5 calories

TDEE = 1761.5 × 1.55 = 2730.3 calories

Target Calories = 2730.3 × 0.8 = 2184.2 calories

Result: This individual should consume approximately 2184 calories daily for fat loss, with a macronutrient distribution of 40% protein, 30% carbohydrates, and 30% fat.

Common Mistakes & Tips

Many people select an activity level lower than their actual daily movement, leading to underestimated calorie needs. Be honest about your daily activities, including NEAT (Non-Exercise Activity Thermogenesis) like walking, standing, and fidgeting. If you have a physically demanding job or walk frequently throughout the day, you likely need a higher activity multiplier than you think.

While it might be tempting to create a large calorie deficit for faster results, this approach often backfires. Deficits greater than 500-750 calories per day can lead to muscle loss, metabolic slowdown, decreased energy, and poor adherence. The Apex Coaching methodology emphasizes sustainable fat loss through moderate deficits that preserve muscle mass and metabolic health.

Focusing only on total calories while ignoring macronutrient distribution is a common mistake. The Apex Coaching approach emphasizes adequate protein intake (0.8-1g per pound of body weight) to preserve muscle mass, especially during fat loss phases. Proper carbohydrate and fat intake is also crucial for hormone production, energy levels, and overall health.

Frequently Asked Questions

We recommend recalculating your calorie needs every 4-6 weeks or after a significant change in body weight (5+ lbs or 2+ kg). As you lose weight, your calorie needs decrease, and as you gain muscle, they may increase. Regular recalculation ensures your nutrition plan continues to align with your current body composition and goals.

The Apex Coaching methodology accounts for exercise in your activity level multiplier, so additional calories burned during planned workouts are already factored into your TDEE. For most people, we don't recommend eating back additional exercise calories unless you're an endurance athlete with extremely high energy expenditure. Focus on hitting your daily target consistently rather than adjusting based on daily activity fluctuations.

If you're not seeing results after consistently following your calorie targets for 3-4 weeks, several factors may be at play. First, ensure you're accurately tracking your intake (many people underestimate). Second, consider adjusting your activity level multiplier or checking for underlying health issues. Third, evaluate your stress levels, sleep quality, and hydration, as these factors significantly impact results. If issues persist, consult with an Apex Coaching specialist for personalized adjustments.
