Understanding Your Calorie & Macro Results

Simple explanations to help you make informed decisions for your health and lifestyle.

1. What is BMR (Basal Metabolic Rate)?

Your Basal Metabolic Rate (BMR) is the baseline amount of energy (calories) your body burns every day just to keep you alive—even if you lay in bed all day without moving. It powers vital functions like breathing, circulating blood, cellular repair, and brain activity.

2. What is TDEE (Total Daily Energy Expenditure)?

TDEE is the actual total number of calories you burn in a 24-hour period. It is calculated by multiplying your BMR by your physical activity level. Eating at your TDEE will keep your weight steady.

3. How Your Body Inputs Affect Your Target

  • Age: Metabolism naturally slows down slightly with age as lean muscle mass decreases.
  • Weight & Height: Larger body mass requires more energy to function daily.
  • Gender: Men typically have higher muscle-to-fat ratios, leading to a slightly higher resting BMR.

4. What is a Macronutrient Split Ratio?

Calories come from three main food groups called Macronutrients:

  • • Protein (4 kcal/g): Essential for repairing muscle, tissues, and keeping you full.
  • • Carbohydrates (4 kcal/g): Your body’s main and fastest source of daily energy.
  • • Healthy Fats (9 kcal/g): Crucial for hormone balance, brain function, and joint health.

Practical Tip for Sustainable Weight Management

To lose weight safely, aim for a gradual caloric deficit of 300–500 kcal per day below your TDEE (aiming for roughly 0.5 kg loss per week). Avoid dropping calories below your BMR without medical supervision to preserve energy and prevent metabolic slowdown.
