What is Nourish Coverage?
Nourish Coverage refers to the estimation of an individual's daily nutritional requirements, encompassing calories, macronutrients (protein, fat, carbohydrates), and essential micronutrients. It's a personalized assessment designed to guide dietary choices for achieving specific health and fitness goals. Understanding your nourish coverage is fundamental to building a balanced diet that supports bodily functions, energy levels, and overall well-being. It's not just about eating enough, but about eating the right balance of nutrients to fuel your body effectively.
Who should use it? Anyone looking to optimize their diet can benefit from understanding their nourish coverage. This includes:
- Individuals aiming for weight management (loss, gain, or maintenance).
- Athletes and fitness enthusiasts seeking to enhance performance and recovery.
- People with specific health conditions requiring dietary adjustments.
- Those simply wanting to improve their general health and energy levels.
- Anyone curious about how much of each nutrient their body needs daily.
Common misconceptions about nourish coverage include the idea that it's a rigid, one-size-fits-all plan. In reality, it's a dynamic estimate that can change based on activity, age, health status, and goals. Another misconception is that focusing solely on calories is sufficient; the quality and balance of macronutrients and micronutrients are equally vital for optimal health. This calculator focuses on the core macronutrient and calorie estimations, providing a solid foundation for dietary planning.
Nourish Coverage Formula and Mathematical Explanation
The calculation of nourish coverage typically begins with estimating the Basal Metabolic Rate (BMR), which is the number of calories your body burns at rest. A widely accepted formula for this is the Mifflin-St Jeor Equation, known for its accuracy. This is then adjusted by an activity factor to determine the Total Daily Energy Expenditure (TDEE), representing the total calories needed per day. Finally, macronutrient targets are derived from the TDEE based on recommended ratios.
Step 1: Calculate Basal Metabolic Rate (BMR)
Using the Mifflin-St Jeor Equation:
- For Men: BMR = (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) + 5
- For Women: BMR = (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) – 161
Step 2: Calculate Total Daily Energy Expenditure (TDEE)
TDEE = BMR × Activity Factor
The Activity Factor is determined by the user's reported activity level:
- Sedentary: 1.2
- Lightly Active: 1.375
- Moderately Active: 1.55
- Very Active: 1.725
- Extra Active: 1.9
Step 3: Adjust TDEE for Health Goals
If the goal is weight loss, a deficit is applied (e.g., TDEE × 0.8). If the goal is weight gain, a surplus is added (e.g., TDEE × 1.2). For maintaining weight, the TDEE remains unchanged.
Step 4: Determine Macronutrient Distribution
Macronutrient targets are calculated based on the adjusted TDEE, with ratios varying slightly based on primary activity type:
- Protein: Generally 1.2-2.2 g per kg of body weight, or a percentage of TDEE (e.g., 20-30%). For strength training, it might lean higher.
- Fat: Typically 20-35% of TDEE. Essential for hormones and nutrient absorption.
- Carbohydrates: The remaining percentage of TDEE, crucial for energy.
*Note: This calculator uses simplified, common ratios for demonstration. Specific micronutrient needs are complex and best assessed by a healthcare professional.*

Practical Examples (Real-World Use Cases)
Example 1: The Active Professional
Scenario: Sarah is a 32-year-old female, 170 cm tall, weighing 65 kg. She works a moderately active job and exercises 4 times a week with a mix of cardio and strength training. Her goal is to maintain her current weight and improve muscle tone.
Inputs:
- Age: 32
- Sex: Female
- Weight: 65 kg
- Height: 170 cm
- Activity Level: Moderately Active
- Health Goal: Maintain Weight
- Primary Activity Type: Strength Training
Estimated Outputs:
- BMR (approx): 1400 kcal
- TDEE (approx): 1400 * 1.55 = 2170 kcal
- Adjusted TDEE (Maintain): 2170 kcal
- Primary Result (Calories): ~2170 kcal
- Protein: ~130 g (approx. 24% of TDEE)
- Fat: ~62 g (approx. 26% of TDEE)
- Carbohydrates: ~270 g (approx. 50% of TDEE)
Interpretation: Sarah needs approximately 2170 calories daily to maintain her weight. With a focus on strength training, a higher protein intake (around 130g) is recommended for muscle repair and growth, balanced with adequate fats and carbohydrates for energy and overall function.
Example 2: The Weight Loss Seeker
Scenario: Mark is a 45-year-old male, 180 cm tall, weighing 90 kg. He has a sedentary job and engages in light walking only 1-2 times a week. He wants to lose weight gradually and safely.
Inputs:
- Age: 45
- Sex: Male
- Weight: 90 kg
- Height: 180 cm
- Activity Level: Sedentary
- Health Goal: Lose Weight
- Primary Activity Type: General Health
Estimated Outputs:
- BMR (approx): 1750 kcal
- TDEE (approx): 1750 * 1.2 = 2100 kcal
- Adjusted TDEE (Lose Weight – 20% deficit): 2100 * 0.8 = 1680 kcal
- Primary Result (Calories): ~1680 kcal
- Protein: ~100 g (approx. 24% of TDEE)
- Fat: ~47 g (approx. 25% of TDEE)
- Carbohydrates: ~200 g (approx. 48% of TDEE)
Interpretation: Mark requires about 2100 calories to maintain his current weight. To achieve gradual weight loss, a daily intake of approximately 1680 calories is estimated, creating a deficit. The macronutrient split prioritizes sufficient protein to preserve muscle mass during weight loss, with fats and carbohydrates making up the remainder.

Key Factors That Affect Nourish Coverage Results
While this calculator provides a valuable estimate, several factors can influence your actual nutritional needs. Understanding these can help you refine your dietary approach:
- Metabolic Rate Variations: Individual metabolic rates can differ due to genetics, muscle mass, and hormonal factors. Someone with a naturally faster metabolism might require more calories than predicted.
- Intensity and Duration of Exercise: The 'Activity Level' is a generalization. Highly intense or prolonged workouts, especially in endurance sports, can significantly increase calorie and carbohydrate needs beyond standard estimates.
- Body Composition: Muscle tissue burns more calories at rest than fat tissue. Individuals with higher muscle mass may have a higher BMR and TDEE than predicted solely by weight and height.
- Age-Related Changes: Metabolism tends to slow down with age, and nutrient absorption can change. While age is an input, individual variations exist.
- Health Conditions and Medications: Certain medical conditions (e.g., thyroid disorders, diabetes) and medications can alter metabolic rate and nutrient requirements. This calculator does not account for these complexities.
- Environmental Factors: Extreme temperatures or high altitudes can slightly increase energy expenditure.
- Dietary Quality and Nutrient Timing: While this calculator focuses on quantity (calories and macros), the quality of food sources (whole vs. processed) and the timing of meals can impact energy levels, satiety, and overall health outcomes.
- Digestive Health: Efficiency of nutrient absorption can vary, impacting how well your body utilizes the food consumed.
