Losing weight effectively requires one key ingredient: calorie control. But how many calories should you eat per day to lose weight safely and sustainably? Use our calorie calculator, learn the average calorie needs, and follow expert-backed tips to reach your goals faster.
Before cutting calories, it's essential to calculate your daily energy requirements based on your age, sex, activity level, and weight goals.
| Goal | Calorie Intake Example (Women) | Calorie Intake Example (Men) |
|---|---|---|
| Maintain Weight | ~1,800–2,200 kcal/day | ~2,200–2,800 kcal/day |
| Mild Weight Loss | ~1,500–1,800 kcal/day | ~1,800–2,400 kcal/day |
| Fast Weight Loss | ~1,200–1,500 kcal/day | ~1,500–1,800 kcal/day |

Knowing the average calorie intake per day can help guide your plan:
| Demographic | Sedentary | Moderately Active | Active |
|---|---|---|---|
| Women (19–30 yrs) | 1,800 | 2,000 | 2,400 |
| Men (19–30 yrs) | 2,400 | 2,600 | 3,000 |
| Older Adults (50+) | 1,600–2,200 | 2,200–2,600 | 2,600–3,000 |
Calories are units of energy from food.
To lose weight, you must maintain a calorie deficit (i.e., consume fewer calories than you burn).
1 pound of fat = ~3,500 calories. A daily deficit of 500–1,000 calories = 1–2 pounds lost per week.
Cutting calories doesn’t mean starving. Smart swaps help:
✅ Eat high-volume, low-calorie foods (e.g., salads, soups)
✅ Choose lean protein (e.g., chicken, tofu, eggs)
✅ Drink more water before meals
✅ Avoid sugary drinks and processed snacks
✅ Use smaller plates to manage portions
Track your calories with apps like MyFitnessPal
Exercise regularly: Combine strength + cardio
Get enough sleep (7–9 hours)
Manage stress: Stress can increase cortisol, leading to cravings
Stay consistent – small steps daily lead to big changes
While cutting calories helps with fat loss, going too low can backfire:
🚫 Slowed metabolism
🚫 Nutrient deficiencies
🚫 Muscle loss
🚫 Fatigue and mood swings
🚫 Risk of binge eating
Never drop below 1,200 calories for women or 1,500 for men unless under medical supervision.
