Weight Loss Formula:
From: | To: |
The 6-month weight loss formula calculates projected weight loss based on a consistent daily caloric deficit over 180 days (6 months). It's based on the principle that 3500 kcal deficit equals approximately 1 pound of weight loss.
The calculator uses the formula:
Where:
Explanation: The formula multiplies your daily deficit by 180 days, then divides by 3500 to convert to pounds lost.
Details: Consistent caloric deficit is the most scientifically validated method for weight loss. This calculator helps set realistic expectations for long-term weight loss goals.
Tips: Enter your average daily caloric deficit in kcal/day. For accuracy, track your actual intake and expenditure over several weeks to determine your true average deficit.
Q1: Is weight loss really this linear?
A: No, weight loss typically slows over time as metabolism adapts. This provides an estimate assuming consistent deficit.
Q2: Why 3500 kcal per pound?
A: This is a longstanding estimate based on fat's energy content, though individual results may vary slightly.
Q3: What's a healthy daily deficit?
A: Typically 300-500 kcal/day for gradual loss, or up to 1000 kcal/day for more aggressive loss under supervision.
Q4: Does this account for plateaus?
A: No, plateaus from metabolic adaptation aren't factored into this calculation.
Q5: Should I adjust my deficit as I lose weight?
A: Yes, as you lose weight your maintenance calories decrease, so you may need to reduce intake further to maintain the same deficit.
