Faster loss requires a larger daily calorie deficit.

Warning: Your calculated calorie intake is below the recommended minimum safety limit (1200 for women, 1500 for men). Consider reducing your weekly loss target.
Formula Used: We calculated your TDEE using the Mifflin-St Jeor equation. To lose 1.0 lbs/week, you need a daily deficit of 500 calories. Your target is TDEE – Deficit.

What is a NowLoss Weight Loss Calculator?
The nowloss weight loss calculator is a specialized planning tool designed to bridge the gap between biological metrics and "financial" energy accounting. Unlike generic calorie counters, this calculator focuses on the nowloss methodology: determining exactly what needs to happen now to achieve a future result.
This tool is ideal for individuals who treat their health goals with the same rigor as a financial audit. It is designed for those who need a precise, mathematical roadmap to weight loss, eliminating guesswork. However, a common misconception is that this calculator dictates a rigid diet. Instead, it provides a "calorie budget" that you can spend on any foods, provided you stay within the limit.
NowLoss Weight Loss Calculator Formula and Mathematical Explanation
The core of the nowloss weight loss calculator relies on the laws of thermodynamics, specifically the energy balance equation. We use the Mifflin-St Jeor Equation, widely considered the most accurate standard for estimating metabolic rates.
Step 1: Calculate BMR
Your Basal Metabolic Rate (BMR) is the energy your body burns at rest.
Men: (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) + 5
Women: (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) – 161
Step 2: Calculate TDEE
Total Daily Energy Expenditure (TDEE) accounts for activity.
TDEE = BMR × Activity Multiplier
Step 3: The Deficit Calculation
To lose 1 lb of fat, you must create a deficit of approximately 3,500 calories. The nowloss weight loss calculator divides this over a week.

Practical Examples (Real-World Use Cases)
Example 1: The Wedding Deadline
Scenario: Sarah (Female, 30, 160 lbs) wants to reach 145 lbs for her wedding in 10 weeks.
Financial Interpretation: This is an "aggressive repayment plan." The high deficit requires strict discipline, similar to paying off a high-interest loan quickly.
Example 2: The Long-Term Health Investment
Scenario: Mark (Male, 45, 240 lbs) wants to reach 200 lbs safely over a year.
Goal: Lose 40 lbs.
Strategy: Low intensity, 0.75 lbs/week.
Daily Deficit: 375 calories.
TDEE: 2,800 calories.
Result: He eats 2,425 calories/day.
Financial Interpretation: This is a "low-risk investment." The lifestyle change is minor, ensuring long-term adherence and reducing the risk of "defaulting" (quitting).
How to Use This NowLoss Weight Loss Calculator
Enter Biometrics: Input your gender, age, current weight, and height accurately. These establish your metabolic baseline.
Select Activity: Be honest. "Moderate" means elevated heart rate exercise 3-5 times a week, not just walking around the office.
Set Your Goal: Choose your target weight and how fast you want to lose it.
Analyze the Budget: The Daily Calorie Budget is your primary metric. This is your "daily spending limit."
Review the Timeline: Check the table to see when you will hit specific milestones.
Key Factors That Affect NowLoss Results
Several variables can influence the accuracy of the nowloss weight loss calculator:
Metabolic Adaptation: As you lose weight, your BMR drops (you become a "smaller engine"). You must recalculate your budget every 10-15 lbs lost.
Water Weight Fluctuations: High sodium or carbs can cause temporary water retention, masking fat loss. This is like market volatility hiding the true trend of an asset.
Calorie Counting Errors: Most people underestimate intake by 20-30%. Accurate tracking is the "auditing" phase of the process.
Hormonal Changes: Cortisol (stress) and insulin sensitivity impact how the body partitions energy, potentially slowing results despite a theoretical deficit.
Nutrient Density: 500 calories of protein affects metabolism differently than 500 calories of sugar (Thermic Effect of Food), though the calculator assumes a standard mixed diet.
Frequently Asked Questions (FAQ)
Can I lose more than 2 lbs per week?
While possible, it is financially risky for your metabolism. Rapid loss often results in muscle loss (depreciating your metabolic asset) and increases the likelihood of regaining the weight.
Why isn't the scale moving despite my deficit?
This is often due to the "whoosh effect" where water replaces lost fat in cells temporarily. Trust the math; if you are in a deficit, you are losing tissue.
Should I eat back my exercise calories?
Generally, no. Fitness trackers often overestimate burns. Treat exercise calories as a "bonus savings account" to accelerate results rather than spending money.
How accurate is the NowLoss weight loss calculator?
It is an estimate based on population averages. Your individual metabolism may vary by +/- 10%. Use the results as a starting point and adjust based on real-world data.
What is the minimum calorie intake?
Medical guidelines suggest women should not drop below 1,200 and men below 1,500 calories without medical supervision to ensure nutrient sufficiency.
Does this calculator work for Ketogenic diets?
Yes. The laws of thermodynamics apply regardless of macro composition. However, Keto may increase your TDEE slightly due to the thermic effect of protein.
What happens when I reach my goal?
You transition to "Maintenance." You will increase your intake to match your new TDEE, effectively balancing your energy budget to stop losing weight.
Can I target fat loss in specific areas?
No. You cannot "spot reduce" fat. The body draws energy from fat stores systemically, determined by genetics.
