How Many Calories Should You Eat Per Day?

Calories. You've heard the word a thousand times. But what exactly is a calorie? And how many do you actually need?

This guide answers both questions — in plain English, no complicated math required.

What Is a Calorie?

A calorie is a unit of energy. Your body uses energy (calories) 24 hours a day — even while you sleep.

Every time you breathe, think, move, or digest food, your body burns calories. The food you eat gives your body the fuel to do all of this.

When you eat more calories than you burn → you gain weight.
When you eat fewer calories than you burn → you lose weight.
When they match → your weight stays the same.

Simple.

How Many Calories Does the Average Person Need?

This depends on your:

• Age — younger people burn more at rest
• Sex — men generally need more calories than women
• Weight and height — bigger bodies burn more
• Activity level — the more you move, the more you need

As a general starting point, here's what major health organizations recommend:

Goal	Women	Men
Maintain weight	1,800–2,200 kcal/day	2,200–2,800 kcal/day
Lose weight	1,400–1,800 kcal/day	1,800–2,200 kcal/day
Gain muscle	2,000–2,400 kcal/day	2,500–3,000 kcal/day

These are rough estimates. Your exact number depends on your specific measurements. (Source: Atlantic Health System)

Why Kuwait's Climate Matters

Kuwait gets extremely hot. Temperatures can reach 45–50°C in summer.

When it's hot, many people become less active. They exercise less. They spend more time indoors with air conditioning.

Research shows this is a real pattern in Kuwait. One study found that the extreme heat leads to a more sedentary lifestyle among both adults and young people. (Source: PubMed/PMC — Evidence for nutrition transition in Kuwait)

What this means for you: If you're less active during summer, your calorie needs are lower. Eating the same amount as when you're more active can lead to gradual weight gain over time.

Pay attention to your activity level when adjusting your calorie intake.

A Simple Way to Estimate Your Calories

Here's an easy formula used by many nutritionists:

Step 1: Find your Basal Metabolic Rate (BMR)

This is the calories your body needs just to exist at rest.

For a rough estimate:

• Men: BMR ≈ Body weight in kg × 24
• Women: BMR ≈ Body weight in kg × 22

Example: A woman who weighs 65kg: 65 × 22 = 1,430 kcal/day (at rest)

Step 2: Multiply by your activity level

Activity Level	Multiply BMR by
Mostly sitting (desk job, little exercise)	× 1.2
Light activity (light exercise 1–3 days/week)	× 1.375
Moderate activity (exercise 3–5 days/week)	× 1.55
Very active (hard exercise 6–7 days/week)	× 1.725

Example: That same 65kg woman, lightly active: 1,430 × 1.375 = ~1,970 kcal/day to maintain weight

To lose weight: subtract 300–500 calories = 1,470–1,670 kcal/day

The Protein Rule: Don't Just Count Calories

Calories matter. But what those calories are made of matters too.

The most important macro for weight loss and muscle preservation is protein.

Why? Protein keeps you full. Protein preserves muscle when you're losing weight. Protein has a higher "thermic effect" — meaning your body burns more calories just digesting it.

A good target: 1.5–2g of protein per kg of body weight per day.

For a 75kg person: aim for 112–150g of protein per day.

This is hard to hit on your own — unless someone is measuring and counting for you.

Questions and Answers

Q: How many calories do I need to lose weight?
A: Most people lose weight by eating 300–500 calories less than their body needs each day. This creates a calorie deficit without being too extreme. Losing 0.5–1kg per week is a healthy, sustainable pace.

Q: How many calories should a woman eat per day in Kuwait?
A: It depends on size and activity, but a rough range is 1,600–2,000 calories to maintain weight. For weight loss, aim for 1,300–1,700 calories. Given Kuwait's hot climate reduces activity for many people, those on the lower end of activity should aim for fewer calories.

Q: What happens if you eat too few calories?
A: Your metabolism can slow down. You may feel tired, lose muscle, and find it harder to lose weight over time. Don't go below 1,200 kcal/day for women or 1,500 kcal/day for men without medical supervision.

Q: Is counting calories necessary?
A: Not necessarily. Research shows that eating high-protein, whole foods naturally reduces overeating without strict calorie counting. But tracking calories for a few weeks helps you understand portion sizes.

Q: How many calories are in a typical Kuwaiti meal?
A: Traditional Kuwaiti dishes like machboos, harees, and majboos with rice and meat can range from 600–1,200 calories per serving. Portion size makes a big difference.

Q: Does exercise increase how many calories I can eat?
A: Yes. The more active you are, the more calories your body needs. A person who exercises 5 days a week can eat 400–600 more calories per day than someone who doesn't exercise and still maintain their weight.

Q: How does LineUpFit help with calorie goals?
A: Each LineUpFit meal comes with clear calorie and macro labels. Our plans are built around specific calorie targets — so you don't have to count anything. Just pick your plan and eat.
