Calorie Deficit Formula:
| From: | To: |
The calorie deficit calculation determines how many calories you should consume daily to achieve weight loss. It's based on subtracting 500 calories from your Total Daily Energy Expenditure (TDEE) to create a sustainable deficit for gradual weight loss.
The calculator uses the simple formula:
Where:
Explanation: A 500-calorie daily deficit typically results in about 1 pound (0.45 kg) of weight loss per week, which is considered a safe and sustainable rate.
Details: Creating a calorie deficit is fundamental to weight loss. By consuming fewer calories than your body burns, you force it to use stored fat for energy, leading to gradual and sustainable weight reduction.
Tips: Enter your TDEE value in kcal/day. Make sure to use an accurate TDEE calculation that considers your age, gender, weight, height, and activity level for best results.
Q1: Why subtract 500 calories specifically?
A: A 500-calorie deficit creates approximately 3500 calories deficit per week, which equals about 1 pound of fat loss, making it a safe and sustainable rate.
Q2: Is this deficit appropriate for everyone?
A: While generally safe for most adults, individuals with very low TDEE or specific medical conditions should consult a healthcare professional before creating a calorie deficit.
Q3: What if I want to lose weight faster?
A: Larger deficits may lead to faster weight loss but can also cause muscle loss, nutrient deficiencies, and metabolic adaptation. It's generally recommended not to exceed a 1000-calorie deficit without medical supervision.
Q4: Should I adjust my deficit over time?
A: Yes, as you lose weight, your TDEE decreases, so you may need to recalculate and adjust your calorie intake periodically to maintain the desired deficit.
Q5: Are there other factors to consider for weight loss?
A: Yes, macronutrient distribution, meal timing, exercise type and intensity, sleep quality, and stress management all play important roles in successful weight loss beyond just calorie counting.
