A Realistic Starting Point

For many people, a moderate calorie deficit is easier to maintain than a very large one.

Estimated Calorie Targets

Goal	Estimated Calories/Day
Maintain weight	0/day
Mild weight loss	0/day
Moderate weight loss	0/day
Faster weight loss	0/day

Your BMR is an estimate of how many calories your body uses at rest. Your estimated daily calorie needs are higher because they include normal movement, exercise, digestion, and daily activity.

Use these numbers as a starting point, not a strict rule. Your actual needs may vary based on body composition, activity, health, medications, and consistency over time.

Next Step

Now that you have an estimated calorie target, learn how to create a realistic calorie deficit without making your diet harder than it needs to be.

Speak with a qualified healthcare professional before making major diet or weight-loss changes, especially if you are pregnant, managing a medical condition, taking medication, or have a history of disordered eating.
