1200 vs 1500 vs 1800 Calories

1,200 Calories:

• Very low — minimum threshold
• Only for short, sedentary women
• Hard to sustain long-term
• Risk of muscle loss
• Often leads to rebound

1,500 Calories:

• Moderate deficit for smaller women
• Works for sedentary individuals
• More sustainable
• Easier to get nutrients
• Good for shorter people

1,800 Calories:

• Good deficit for most active women
• Works for smaller men
• Very sustainable
• Room for treats
• Supports exercise

Almost nobody, honestly. 1,200 calories is the absolute minimum for women and should only be used if:

• You're under 5'2" AND sedentary
• You're elderly with very low activity
• Under medical supervision

For everyone else, 1,200 calories is too low. You'll be hungry, tired, and likely to quit. It's also hard to get adequate protein and micronutrients at this level.

Better approach: Start at 1,400-1,600 calories and adjust based on results.

1,500 calories works well for:

• Women 5'4" and under with light activity
• Women 5'5"-5'7" who are mostly sedentary
• Anyone who finds 1,800 calories too slow for fat loss

This is a sustainable deficit for smaller women that still allows for adequate nutrition and occasional flexibility. If you're moderately active, you might need more.

1,800 calories (or more) is right for:

• Active women
• Most men (1,800-2,200 for deficit)
• Taller individuals
• Anyone who exercises 3+ times per week

At 1,800 calories, you can eat satisfying meals, fuel your workouts, and still lose weight at a healthy rate. This is the "goldilocks" range for most people.
