How Many Calories Should I Eat a Day?
"How many calories should I eat?" has no single answer — it depends on your size, activity, and goal. But the process for finding your number is straightforward. It starts with your maintenance calories and adjusts from there.

Start With Maintenance (TDEE)
Your maintenance level is your TDEE — the calories that keep your weight stable. Calculate it first, because every goal is defined relative to this number. Generic figures like "2,000 calories a day" are just population averages and rarely match any specific person.
Adjust for Your Goal
- Weight loss: eat 15–20% below TDEE.
- Maintenance: eat at TDEE.
- Muscle gain: eat 5–15% above TDEE.
Our calorie calculator gives you targets for all three at once so you can pick the one that fits your current goal.

Realistic Examples
A moderately active woman with a TDEE of 2,100 calories would eat roughly 1,700 to lose fat, 2,100 to maintain, or about 2,300 to gain muscle. A man with a TDEE of 2,800 would target around 2,250, 2,800, or 3,100 respectively. The exact split into protein, carbs, and fat comes from a macro calculator.
Calories Count — But So Does Quality
Total calories drive weight change, but food quality drives how you feel and perform. Build meals around protein, vegetables, fruit, whole grains, and healthy fats. These foods are filling and nutrient-dense, making your calorie target far easier to hit without hunger.
Frequently Asked Questions
+How many calories should I eat to lose weight?
Eat 15–20% below your TDEE. For many people that's around 1,500–2,000 calories, but calculate your own TDEE for an accurate target.
+Is 1,200 calories a day enough?
For most adults 1,200 is very low and hard to sustain. Base your intake on your TDEE rather than a fixed low number to protect muscle and energy.
+Do I need to count calories forever?
No. Counting for a while teaches portion awareness; many people then maintain results with habits rather than constant tracking.
Conclusion
The right calorie intake is personal: find your TDEE, adjust it for your goal, and focus on nutritious, filling foods. Calculate your number, give it a few weeks, and refine based on real results.
