The Walking Weight Estimator projects potential weight change from a recurring walking plan and a chosen calorie-balance adjustment. It converts estimated walking calories into a weekly energy total, then translates that total into a rough body-weight change.
Real weight change is not perfectly linear because appetite, activity compensation, water balance, and metabolic adaptation can alter the outcome. Use the result as a scenario, not a guarantee.
1. Enter body weight
Walking calorie estimates scale with body weight.
2. Build the weekly plan
Set minutes per walk and walks per week.
3. Choose pace
Select the closest MET category.
4. Add a calorie-balance scenario
Use negative values for an added deficit and positive values for added intake.
5. Review the projection
Compare weekly, four-week, and twelve-week estimates.
Weekly walking calories = MET × 3.5 × weight ÷ 200 × minutes per walk × walks per week.
Estimated weekly weight change = (walking calories − additional daily calorie balance × 7) ÷ 7,700 kcal/kg.
A positive displayed change represents estimated weight loss under the model; a negative value represents gain.
The 7,700 kcal/kg conversion is a planning approximation and actual change often slows or fluctuates.
Given: 80 kg, 40 minutes, 5 days/week, moderate 3.5 MET, no diet adjustment.
Calculation: Weekly walking calories = 3.5 × 3.5 × 80 ÷ 200 × 40 × 5 = 980 kcal. Weekly change = 980 ÷ 7,700 = 0.127 kg.
Result: Four-week projection ≈ 0.51 kg.
Walking is valuable, but its calorie contribution may be modest relative to total daily energy intake.
It means the entered calorie-balance scenario exceeds the estimated walking expenditure and projects weight gain.
Enter only the daily change relative to your current baseline, not total food intake.
Not necessarily. Body weight, appetite, and activity behavior can change over time.
No. It is a simplified energy-balance scenario and does not assess nutrient needs or medical considerations.
