If you’ve ever wondered why one friend can eat more without gaining weight while you seem to gain from looking at a doughnut, the answer lies in your personal calorie burn. Your daily calorie expenditure isn’t a fixed number — it changes with your age, sex, weight, and how much you move.
Average daily calorie burn for women: 1,600–2,200 calories · Average daily calorie burn for men: 2,200–3,000 calories · Calories in 1 kg of body fat: 7,700 calories · Calories burned walking 10,000 steps: 300–500 calories

Is burning 500 calories per day enough?
What is a 500-calorie deficit?
A 500-calorie deficit means you consume 500 fewer calories than your body burns each day. According to the NASM (a leading fitness organisation), subtracting 500 to 1,000 calories from your total daily energy expenditure (TDEE) is a standard recommendation for weight loss. The idea is simple: create a shortfall so your body taps into stored fat for fuel.
How much weight loss can you expect from a 500-calorie deficit?
InBody (body composition technology company) states that a 300 to 500 kcal daily deficit typically leads to losing about 0.5 to 1 pound per week. That’s roughly 0.2–0.5 kg per week. Over a month, a consistent 500-calorie deficit could result in about 2–4 pounds (0.9–1.8 kg) of weight loss. Individual results vary depending on starting weight, diet composition, and adherence.
Is a 500-calorie deficit safe for everyone?
For most adults, a 500-calorie deficit is considered safe and sustainable. However, InBody advises not to eat fewer calories than your basal metabolic rate (BMR), as doing so can slow metabolism and harm health. People who are underweight, pregnant, or have medical conditions should consult a doctor before starting any calorie deficit.
For most dieters, a 500-calorie daily deficit offers the best balance of steady weight loss without triggering metabolic slowdown. Going below BMR is where the risks pile up.
How many calories do 10,000 steps burn?
Factors that affect calories burned per step
The number of calories you burn walking 10,000 steps depends on your body weight, walking pace, and terrain. A person weighing 70 kg (154 lb) burns approximately 300–400 calories during those steps, according to NASM (fitness certification body). Heavier individuals burn more, lighter individuals less. Walking uphill or at a brisk pace also increases calorie expenditure.
How does 10,000 steps compare to other exercises?
10,000 steps is roughly 8 km (5 miles) for most people. Compared to running, swimming, or cycling, walking burns fewer calories per minute. But walking is low-impact and accessible. Aviva (UK health insurer) provides BMR calculators that factor in activity levels, showing that even light activity adds up over a day.
How to increase calorie burn while walking
To burn more calories per step, try interval walking: alternate between a moderate pace and a brisk pace. Add hand weights, walk on an incline, or use a weighted vest. CDC (U.S. health agency) recommends 150 minutes of moderate-intensity exercise per week, which can be achieved with a daily 30-minute brisk walk.
How many calories to burn to lose 1 kg?
The 7,700-calorie rule for losing 1 kg of fat
One kilogram of body fat equals approximately 7,700 calories. This is a widely cited benchmark in weight-loss science. To lose 1 kg of fat, you need to create a total deficit of 7,700 calories through diet, exercise, or both. InBody (body composition technology company) confirms this figure.
How long does it take to burn 7,700 calories?
With a daily deficit of 500 calories, you would lose 1 kg in about 15 days (7,700 ÷ 500 ≈ 15.4). A 300-calorie daily deficit would take approximately 26 days. The timeline depends entirely on the size of your daily deficit. NASM (fitness organisation) recommends a deficit of 500–1,000 calories per day for safe weight loss of 0.5–1 kg per week.
Combining diet and exercise to reach the deficit
The most sustainable approach is to split the deficit between diet and exercise. For example, eating 300 fewer calories and burning 200 additional calories through activity gives you a 500-calorie total deficit. ATHLEAN-X (fitness training platform) suggests starting with a moderate 200-calorie reduction to avoid hunger and adherence problems.
Not all weight lost from a deficit is pure fat. Water weight and muscle loss can contribute, especially if the deficit is too aggressive or protein intake is low. Focus on fat loss, not just scale weight.
How many calories should I burn a day exercising?
General exercise calorie guidelines for health and weight loss
The CDC (U.S. health agency) recommends at least 150 minutes of moderate-intensity exercise per week for general health. That translates to about 20–25 minutes of brisk walking daily, burning roughly 100–150 calories per session. For weight loss, many experts suggest 200–400 calories per exercise session, depending on intensity and duration.
How to calculate your personal exercise calorie goal
First, determine your TDEE using a BMR calculator. Then decide your deficit. If your TDEE is 2,500 calories and you want a 500-calorie deficit, your total intake should be 2,000 calories. Your exercise calorie burn should be part of that deficit, not an “extra” you eat back. Aviva (UK health insurer) offers a free BMR calculator based on the Mifflin‑St Jeor equation to get your baseline.
Balancing exercise calories with dietary intake
It’s common to feel hungrier after exercise, but resist the urge to fully compensate with extra food. A 200-calorie snack after a 400-calorie workout still leaves a net 200-calorie burn. InBody (body composition technology company) warns against eating below BMR, as that can backfire. The goal is a moderate, sustainable deficit.
Does walking burn belly fat?
Can walking specifically target belly fat?
Walking alone cannot spot-reduce belly fat. Fat loss occurs systematically across the body, not just in one area. Cleveland Clinic (U.S. academic medical centre) explains that genetics largely determine where fat is lost first. Many people lose fat from their face or limbs before their midsection.
How walking contributes to overall body fat reduction
Walking reduces overall body fat over time, which includes abdominal fat. A consistent walking habit creates a calorie deficit and improves insulin sensitivity, both of which support fat loss. NASM (fitness organisation) notes that even moderate activity like walking can lower visceral fat when combined with a balanced diet.
Best practices for walking to reduce belly fat
To maximise belly fat loss, walk at a brisk pace (3–4 mph) for 30–60 minutes most days. Include incline walking or intervals to increase intensity. CDC (U.S. health agency) says that more exercise (300 minutes per week) yields greater health and weight loss benefits. Consistency matters more than intensity.
How many calories does the average person burn a day without exercise?
Understanding BMR vs. TDEE
Your basal metabolic rate (BMR) is the calories your body needs at complete rest to sustain life — breathing, circulation, cell production. Cleveland Clinic (U.S. academic medical centre) reports that BMR accounts for 60–75% of total daily calorie burn. Your TDEE adds physical activity (including non‑exercise movement) and the thermic effect of food.
Factors that influence your resting calorie burn
Several factors determine your BMR: age (it declines with age), sex (men usually have higher BMR due to more muscle mass), weight, and body composition. According to InBody (body composition technology company), the Mifflin‑St Jeor equation is among the most accurate for estimating BMR: for men, 10 × weight(kg) + 6.25 × height(cm) − 5 × age(y) + 5; for women, subtract 161.
How to estimate your own non‑exercise calorie burn
Multiply your BMR by an activity factor. For a sedentary person (little or no exercise), the multiplier is 1.2. InBody (body composition technology company) lists standard multipliers: lightly active 1.375, moderately active 1.55, very active 1.725, extra active 1.9. Non‑exercise activity thermogenesis (NEAT) — fidgeting, walking to the car, housework — can add 200–500 calories daily, as noted by Calculator.net (online health tool).
The implication: your baseline burn without structured exercise is still substantial. Most people burn 1,400–1,700 calories just to exist, before moving a muscle.
How to calculate your personalized daily calorie burn
Follow these steps to find your own target. The numbers come from validated equations used by health organisations.
- Calculate your BMR using the Mifflin‑St Jeor equation. Use an online calculator like Aviva’s (UK health insurer) tool or do the math: 10 × weight(kg) + 6.25 × height(cm) − 5 × age(y) + 5 (men) or −161 (women).
- Choose your activity multiplier from the InBody standard scale: 1.2 (sedentary), 1.375 (light), 1.55 (moderate), 1.725 (very active), 1.9 (extra active).
- Multiply BMR by the multiplier to get your TDEE. That’s the calories you need to maintain your current weight.
- Set your deficit for weight loss: subtract 300–500 calories (or up to 1,000 for faster loss, per NASM (fitness organisation)). Never go below your BMR.
- Track your actual intake and burn with a reliable app or food diary for at least two weeks, then adjust.
Using a generic “2,000 calories a day” recommendation can leave you under‑ or over‑eating. A personalised calculation avoids the guesswork and puts you in control of your own metabolism.
“In the UK, the NHS recommends a general daily calorie intake of 2,000 calories for women and 2,500 for men to maintain weight. But these are averages — individual needs vary widely.”
“Most female adults need 1,600–2,200 calories per day to maintain weight, while most male adults need 2,200–3,000, according to the 2020–2025 Dietary Guidelines for Americans.”
“The Mifflin‑St Jeor equation is one of the most accurate formulas for estimating BMR. Even then, individual metabolism can differ by up to 200 calories per day due to genetics and muscle mass.”
Cleveland Clinic (U.S. academic medical centre)
The number of calories you should burn each day isn’t one-size-fits-all. It depends on your BMR, your activity level, and your goal — whether maintaining weight, losing fat, or fuelling performance. For the average UK reader trying to shed a few pounds, the safest path is a 300–500 daily deficit built on a personalised TDEE calculation, not a random app target. Your body gives the final answer: if you’re losing about 0.5 kg per week without feeling deprived, you’ve found your number. For anyone chasing weight loss, the choice is clear: calculate your own baseline, or guess and risk frustration.

Frequently asked questions
How many calories should I burn to lose 1 pound?
To lose 1 pound (0.45 kg) of body fat, you need a deficit of about 3,500 calories. This is a well‑established rule in weight‑loss science.
What is the safest calorie deficit per day?
A deficit of 300–500 calories per day is generally considered safe for most adults. Going above 1,000 calories daily may lead to muscle loss and nutritional deficiencies. NASM (fitness organisation) recommends staying within this range.
Do I need to burn calories every day to lose weight?
No, weight loss depends on overall calorie balance over time. You can create a deficit through diet alone, but combining diet and exercise is more sustainable. Missing a day won’t derail progress.
How many calories do I burn sleeping?
During sleep, your body continues to burn calories at about 85–90% of your BMR. For an average person, that’s roughly 40–60 calories per hour, depending on weight and age.
Can I lose weight by only dieting without exercise?
Yes, but exercise offers additional benefits like preserving muscle mass, improving cardiovascular health, and boosting metabolic rate. A pure diet approach can work, but it’s often harder to maintain.
How many calories should a 14‑year‑old burn daily?
Teenagers have higher calorie needs due to growth and development. A 14‑year‑old girl typically needs 1,800–2,400 calories per day, while a boy of the same age needs 2,000–2,800, according to NHS (UK health service) guidelines.
Is it better to burn calories through exercise or diet?
Both matter, but diet generally has a bigger impact on creating a deficit because it’s easier to skip 500 calories of food than to burn 500 calories through exercise. The most effective approach combines moderate diet cuts with regular activity.
How many active calories should I burn each day?
Active calories — those burned through intentional exercise — can range from 150–400 per day for general health, or more if you’re training for weight loss. The CDC (U.S. health agency) recommends at least 150 minutes of moderate exercise weekly, which equates to roughly 150–250 active calories per day for a typical person.
