Description

Plan your calorie deficit, macro split, and weekly check-ins based on body stats, goal rate, and lifestyle for sustainable fat loss without muscle loss.

Use Cases

Prevents muscle loss.

Inputs/Variables Explained

We ask for weight loss goal rate, current weight, activity level, diet preference, gender, age group, and height because these set safe deficits (e.g., 500 kcal for 1 lb/week). These inputs support sustainable loss. Limitation: the tool uses estimates and may not reflect metabolic adaptation; track progress and adjust.

Output Examples

Fitness Deficit Planner

1. Calculate Daily Calories and TDEE

To calculate your Total Daily Energy Expenditure (TDEE), we need to consider your activity level and then apply the desired deficit for weight loss.

Estimated TDEE Calculation

  • Activity Level: Moderately Active
  • BMR (Basal Metabolic Rate): Approximate value for females under 30 and under 60 is around 1,400 - 1,600 calories.

Using an average BMR of 1,500 calories and applying the activity multiplier for "Moderately Active" (1.55):

  • TDEE = BMR x Activity Level
  • TDEE = 1,500 x 1.55 = 2,325 calories/day

Daily Caloric Intake for Weight Loss

  • Desired Weight Loss: 1 lb/week
  • Caloric Deficit: 500 calories/day (1 lb of fat = 3,500 calories)

Daily Caloric Goal:

  • 2,325 - 500 = 1,825 calories/day

2. Macro Breakdown

Balanced Macros Distribution

For a balanced macro approach, we can use the following ratios:

  • Carbohydrates: 50%
  • Protein: 25%
  • Fats: 25%

Daily Macro Targets

  • Total Calories: 1,825
  • Carbohydrates:
    • 50% of 1,825 = 912.5 calories
    • Grams: 912.5 / 4 = 228 g
  • Protein:
    • 25% of 1,825 = 456.25 calories
    • Grams: 456.25 / 4 = 114 g
  • Fats:
    • 25% of 1,825 = 456.25 calories
    • Grams: 456.25 / 9 = 51 g

Summary of Daily Targets:

  • Calories: 1,825
  • Carbohydrates: 228 g
  • Protein: 114 g
  • Fats: 51 g

3. Sustainable Weight Loss

Key Principles:

  • Gradual Change: Aiming for 1 lb/week is a sustainable approach that allows for lifestyle changes to be maintained over time.
  • Balanced Diet: Ensuring a balanced intake of macros helps support overall health, energy levels, and muscle maintenance.
  • Consistency: Stick to the plan and be adaptable to changes; some weeks may result in less or more weight loss.
