Frequently asked questions
What is a safe daily calorie deficit?
A safe calorie deficit is typically 500-750 calories per day, leading to 1-1.5 pounds of weight loss weekly without compromising health or metabolism.
How accurate are calorie deficit calculations?
Calculations provide good estimates based on established formulas, but individual metabolism varies. Monitor progress and adjust as needed for optimal results.
Can I lose weight faster with a larger deficit?
Extreme deficits over 1000 calories daily can slow metabolism, cause muscle loss, and aren't sustainable long-term. Moderate deficits work better.
