Daily calorie needs for healthy aging

As we age, our bodies naturally burn fewer calories — even at rest. Daily calorie needs refer to the amount of energy your body requires to support essential functions like breathing, digestion, and circulation.

For older adults, especially those over 60, factors such as slower metabolism, reduced muscle mass, and lower activity levels all affect how many calories you truly need.

Understanding your ideal daily intake helps you avoid overeating, prevent unintentional weight gain, and make sure your body still gets enough fuel to stay strong, active, and healthy.

Several factors affect your daily calorie requirements. For example, men typically have higher caloric needs than women due to their larger muscle mass and body size.

Similarly, younger individuals and those with higher muscle mass or more active lifestyles require more calories to support their energy expenditure. It's important to consider these factors when calculating your caloric needs to ensure accuracy.

How seniors can calculate their daily calorie needs

As we get older, our metabolism slows down, and our calorie needs decrease — even if our routines stay the same. That’s why it’s especially important for seniors to understand how much energy their body truly needs. One simple way to estimate your daily calorie needs is to multiply your weight in kilograms by 30.

Weight in kg × 30

This rough estimate works for older adults with a light to moderate activity level. However, it doesn’t take into account important details like:
  • slowed metabolism with age
  • reduced muscle mass
  • medical conditions or medications
  • mobility and activity limitations
That’s why we recommend taking our short quiz — it automatically calculates your personalized calorie needs, based on your age, activity level, and health goals. Let the plan adjust to your lifestyle — not the other way around.

How to calculate calorie intake

  • 1Adjust for Weight Goals

    If you're aiming to lose weight, subtract 500-1,000 calories from your maintenance calories to create a deficit. For weight gain, add 500-1,000 calories to your maintenance calories.
  • 2Monitor and Adjust

    Keep track of your progress and adjust your calorie intake as needed. If you're not seeing the desired results, you may need to reevaluate your calorie needs or physical activity level.
  • 3Consider Nutritional Quality

    Focus on consuming nutrient-dense foods that provide vitamins, minerals, and other essential nutrients, rather than just counting calories. A balanced diet is crucial for overall health and well-being.

    With Unimeal, we'll help you create a diet plan that meets your nutritional needs while supporting your health goals.

How seniors can safely create a calorie deficit

To lose weight at any age, you need to consume fewer calories than your body burns — this is called a calorie deficit. But for seniors, it's important to do this gently and safely, without risking muscle loss or nutritional deficiencies.

How to support a healthy metabolism after 60:

  • Stay physically active — even light daily movement like walking or stretching helps

  • Include strength training — maintaining muscle mass is key for metabolic health

  • Eat enough protein — to prevent muscle loss while losing fat

  • Stay well-hydrated — water supports digestion and metabolism

  • Avoid skipping meals — regular, balanced meals help stabilize energy levels

For most older adults, a safe calorie deficit is about 300–500 calories per day. Our quiz will help you find your optimal target based on your age, lifestyle, and health conditions.

Calorie deficit calculator

Our calorie calculator is designed specifically for older adults. It takes into account your age, weight, height, gender, and lifestyle to provide a personalized recommendation that suits your body’s changing needs.

As we get older, our metabolism naturally slows down, and it becomes more important to avoid both overeating and undereating. With just a few simple inputs, you’ll receive a clear daily calorie target that helps support healthy weight, stable energy levels, and overall well-being — without guesswork or strict rules.

How many calories should I burn a day?

Staying active is essential for healthy aging. Regular movement helps manage weight, keeps joints flexible, supports heart health, and boosts mood.

While there's no one-size-fits-all number of calories to burn daily, older adults are encouraged to aim for at least 150 minutes of moderate-intensity activity per week — like brisk walking, gardening, or swimming. Even light activities done consistently can make a difference.

Remember: it’s not about pushing yourself to exhaustion — it’s about moving in ways that feel good and keep your body functioning well.

Summary

Maintaining a healthy balance between the calories you eat and burn becomes especially important with age. It supports weight management, helps prevent age-related health issues, and improves overall quality of life. Combined with regular, joint-friendly physical activity, a well-adjusted calorie intake can significantly boost energy, mood, and long-term well-being.
