Calorie Deficit Formula:
| From: | To: |
A calorie deficit occurs when you consume fewer calories than your body expends. This is the fundamental principle behind weight loss, as your body taps into stored fat for energy when faced with a calorie deficit.
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 an appropriate calorie deficit is essential for effective and sustainable weight loss. Too large a deficit can lead to muscle loss, nutrient deficiencies, and metabolic adaptation, while too small a deficit may not produce noticeable results.
Tips: Enter your calculated TDEE value in kcal. The calculator will subtract 500 calories to determine your recommended daily calorie intake for weight loss. Ensure your TDEE calculation is accurate for best results.
Q1: Why subtract 500 calories specifically?
A: A 500-calorie deficit creates about 1 pound of weight loss per week, which is considered safe and sustainable for most women.
Q2: Can I create a larger calorie deficit for faster results?
A: While possible, larger deficits may lead to muscle loss, nutrient deficiencies, and metabolic slowdown. It's generally recommended not to go below 1200 calories daily without medical supervision.
Q3: Should calorie deficit be adjusted over time?
A: Yes, as you lose weight, your TDEE decreases, so your calorie deficit should be recalculated periodically to continue progress.
Q4: What if I'm very active or have a high TDEE?
A: Those with higher activity levels may be able to sustain a slightly larger deficit, but the 500-calorie reduction remains a good starting point for most women.
Q5: Are there any health considerations?
A: Women should ensure they're getting adequate nutrition and not dropping below minimum calorie requirements. Consult a healthcare provider before starting any weight loss program.
