Lose 30 Pounds in 3 Months: Your Timeline
Discover exactly how long it will take you to lose 30 pounds based on your unique metabolism.
Lose 30 Pounds in 3 Months
Science-based predictions using the Mifflin-St Jeor equation
How is this calculated?
Mifflin-St Jeor Equation (1990):
Men: BMR = 10×weight(kg) + 6.25×height(cm) - 5×age + 5
Women: BMR = 10×weight(kg) + 6.25×height(cm) - 5×age - 161
This equation has been validated as the most accurate predictor of Resting Metabolic Rate in clinical studies.
How Long Does It Take to Lose 30 Pounds in 3 Months?
The timeline for losing 30 pounds depends on several factors: your current weight, metabolism, activity level, and consistency. Our calculator uses the Mifflin-St Jeor equation—the gold standard in metabolic science—to give you a realistic projection.
The Role of Metabolism
Your metabolism determines how efficiently your body converts food into energy. A sluggish metabolism can add weeks or even months to your weight loss timeline. That's why the calculator shows two projections:
- ●Standard Diet (Grey Line): Based on typical caloric deficit alone.
- ●Metabolic Support (Green Line): What's possible with optimized cellular energy production.
The Science Behind the Calculator
This tool uses the Mifflin-St Jeor Equation, which has been shown in clinical studies to be the most accurate predictor of Resting Metabolic Rate (RMR). Combined with your activity level, we calculate your Total Daily Energy Expenditure (TDEE) and project your weight loss based on a safe, sustainable caloric deficit.
