what calorie deficit should i be in to lose weight
For healthy, sustainable weight loss, most people do best with a moderate calorie deficit of about 300–500 calories per day below maintenance, which typically leads to roughly 0.5–1 lb (0.25–0.5 kg) of weight loss per week. Larger deficits (up to around 1,000 calories per day) can be used short term for some people but are harder to stick to and increase the risk of fatigue, muscle loss, and nutrient gaps.
Quick Scoop: The “Right” Deficit
- Common safe range: about 300–500 calories per day below what you need to maintain your weight.
- Typical result: about 0.5–1 lb (0.25–0.5 kg) of weight loss per week for most adults.
- Higher but still often acceptable for some: up to ~1,000 calories per day deficit, giving up to ~1–2 lb (0.5–1 kg) loss per week, if you still meet minimum calorie needs and feel well.
- Important lower limits often suggested: roughly at least 1,200 calories/day for many women and 1,500 for many men, so you still get enough nutrients.
A simple way to think about it:
Small to moderate deficit you can live with for months beats a huge deficit you can only handle for a week.
How to Find Your Deficit
- Estimate maintenance calories (TDEE).
- This is how many calories you need to maintain your current weight based on age, sex, height, weight, and activity level.
* You can use an online TDEE or calorie‑deficit calculator to get a starting number.
- Subtract your target deficit.
- Example: If your maintenance is 2,200 calories, a 500‑calorie deficit target would put you around 1,700 calories per day.
* If you are smaller, older, or less active, a 300‑calorie deficit is often safer and more comfortable.
- Check that you don’t drop too low.
- Avoid going below those rough minimums (≈1,200 for many women, 1,500 for many men) unless supervised by a clinician, because nutrient intake becomes very hard.
What Most Experts Suggest
- Good default for most people: Start with ~300–500 calorie deficit per day and reassess every few weeks.
- When a larger deficit might be used: Some guidelines allow up to ~1,000 calories/day deficit if your maintenance calories are high and you still meet minimum intakes and feel okay.
- Weight‑loss speed target: Aim for about 0.5–2 lb (0.25–1 kg) per week; going faster raises the risk of muscle loss, nutrient deficiencies, and rebound weight gain.
If you share your age, sex, height, weight, and activity level, a more personalized example range can be outlined (still not a medical diagnosis), but for most, that 300–500‑calorie daily deficit is the safest starting point.
