What Are Maintenance Calories?
Your maintenance calories — also called your TDEE (Total Daily Energy Expenditure) — are the total number of calories your body burns in a day. When you eat exactly this amount, your weight stays the same. Not more, not less.
Think of maintenance calories as your body's energy equilibrium point. They account for everything your body does in a day: keeping your organs functioning, digesting food, walking around, exercising, and even thinking.
⚖️ Simple definition: Maintenance calories = the number of calories that keeps your weight stable. Eat less and you lose weight. Eat more and you gain weight.
Why Knowing Your Maintenance Calories Matters
Your maintenance calories are the starting point for every nutrition goal — whether you want to lose fat, build muscle, or simply eat in a way that supports your health without obsessing over every meal.
Without knowing your maintenance calories, you have no baseline. You're guessing at how much to eat, which makes achieving any goal far harder and more frustrating than it needs to be.
Fat Loss
Eat below maintenance to create a calorie deficit
Maintenance
Eat at maintenance to keep your weight stable
Muscle Gain
Eat above maintenance to support muscle growth
How to Calculate Your Maintenance Calories
The most accurate way to estimate your maintenance calories is to use a TDEE calculator that takes into account your age, sex, height, weight, and activity level. The calculator uses a validated scientific formula to estimate your BMR (Basal Metabolic Rate) and then multiplies it by an activity factor.
Men: BMR = (10 × kg) + (6.25 × cm) − (5 × age) + 5
Women: BMR = (10 × kg) + (6.25 × cm) − (5 × age) − 161
Step 2: Multiply BMR by your activity level
Maintenance calories = BMR × activity multiplier

Maintenance calories vary enormously between people. Here are some rough average ranges to give you an idea of where most people fall:
| Activity Level | Average Woman | Average Man |
|---|---|---|
| Sedentary | 1,600–1,800 kcal | 2,000–2,200 kcal |
| Lightly active | 1,800–2,000 kcal | 2,200–2,500 kcal |
| Moderately active | 2,000–2,200 kcal | 2,500–2,800 kcal |
| Very active | 2,200–2,500 kcal | 2,800–3,200 kcal |
| Athlete | 2,500–3,000+ kcal | 3,200–4,000+ kcal |
These are rough averages only — your personal maintenance calories depend on your specific height, weight, age, body composition, and true activity level. Use our calculator for a personalised estimate.
How to Find Your True Maintenance Calories
Calculators give you a great starting estimate, but your true maintenance calories can only be found through real-world tracking. Here's how:
- Calculate your estimated TDEE using our calculator
- Eat that number of calories consistently for 2–3 weeks
- Weigh yourself at the same time each morning and track your weekly average
- If your weight is stable — that's your maintenance. If you're losing weight, your true maintenance is higher. If you're gaining, it's lower
- Adjust by 100–150 calories and repeat until your weight is stable
💡 Pro tip: Weigh yourself every morning and take the weekly average — don't judge by single daily readings. Weight fluctuates by 1–2kg day to day due to water, food volume and other factors. The weekly trend is what matters.
What Affects Your Maintenance Calories?
Your maintenance calories are not fixed — they change over time based on a number of factors:
Body weight and composition
Larger bodies burn more calories. As you lose weight, your maintenance calories decrease. As you gain muscle, they increase slightly — muscle tissue burns more calories at rest than fat tissue.
Age
Maintenance calories tend to decrease with age, partly due to declining muscle mass and partly due to hormonal changes. This is why many people find it easier to gain weight as they get older eating the same amount they always have.
Activity level
This is the most variable factor and the one you have the most control over. More movement — both formal exercise and everyday activity like walking — increases your maintenance calories significantly.
Hormones and health
Thyroid function, insulin sensitivity, cortisol levels, and other hormonal factors can all affect how many calories your body burns. If you find your maintenance calories are significantly different from what calculators estimate, it may be worth speaking to a healthcare professional.
Maintenance Calories for Weight Management
Eating at your maintenance calories is an excellent long-term strategy for people who have reached their goal weight and want to stay there without constant restriction. It allows you to eat satisfying, nutritious meals without gaining or losing weight.
Many people find that after a period of fat loss, spending time eating at maintenance — sometimes called a diet break — helps restore energy levels, improve mood, and reset hunger hormones before continuing with further fat loss if desired.

Are maintenance calories the same as TDEE?
Yes — maintenance calories and TDEE (Total Daily Energy Expenditure) refer to the same thing. Both describe the total number of calories your body burns in a day, which is also the amount you need to eat to maintain your current weight.
How do I know if I'm eating at maintenance?
The most reliable sign is that your weight stays stable over 2–3 weeks when tracked consistently. Minor daily fluctuations are normal, but your weekly average should remain roughly the same.
Do maintenance calories change if I exercise more?
Yes — if you increase your activity level significantly, your maintenance calories increase too. This is why it's important to recalculate your TDEE if your lifestyle changes, such as starting a new training programme or changing jobs.
Should I eat my maintenance calories on rest days?
Generally yes — unless you're specifically doing calorie cycling (eating more on training days and less on rest days). For most people, eating a consistent amount each day is simpler and just as effective.
Why am I gaining weight eating at my maintenance calories?
If you're gaining weight while eating what you believe to be your maintenance calories, your true maintenance is likely lower than you estimated. This could be because your activity level is lower than you think, or because you're underestimating your food intake. Try reducing by 100–200 calories and monitoring for two to three weeks.
