What This Calculator Does

This calorie deficit calculator estimates your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation, calculates your Total Daily Energy Expenditure (TDEE) based on activity level, and determines the daily calorie target needed to achieve your desired weekly weight loss rate. It also projects the timeline to reach your goal weight and flags targets that fall below medically recommended minimums.

Common Mistakes to Avoid

• Setting too aggressive a deficit. Losing more than 1% of body weight per week increases muscle loss, metabolic adaptation, and the likelihood of regaining weight.

• Not adjusting as you lose weight. Your BMR and TDEE decrease as you get lighter. Recalculate every 10 to 15 pounds lost to maintain your target deficit.

• Ignoring the minimum safe intake. Women should not consume below 1,200 calories/day and men should not go below 1,500 calories/day without medical supervision.

• Relying solely on calorie counting without considering food quality. A 2,000-calorie diet of whole foods supports better satiety, energy, and health markers than 2,000 calories of processed foods.
