Frequently asked questions
Even when you are in a calorie deficit, weight loss can stall due to:
water retention
inaccurate tracking
reduced daily movement
hormonal fluctuations
Fat loss can still be happening even if the scale isn’t moving immediately.
Yes, very low calorie intake can reduce:
energy levels
daily activity
metabolic rate over time
This can slow down progress and make fat loss harder to sustain.
Losing 10kg depends on your deficit and consistency.
A realistic pace is:
0.25–0.75 kg per week
This means it can take:
around 3 to 6 months or more
Weight can fluctuate daily due to:
water retention
salt intake
carbohydrate intake
digestion
This is normal and does not mean fat loss has stopped.
Weight loss includes:
fat
water
muscle
Fat loss specifically refers to losing body fat, which is the real goal for most people.
Yes, by:
eating enough protein
doing resistance training
avoiding very aggressive calorie deficits
This helps preserve lean muscle while losing fat.
Yes.
As your body weight decreases:
your calorie needs drop
your maintenance level lowers
Adjusting calories helps maintain consistent progress.
This is often due to:
metabolic adaptation
reduced calorie burn
hitting a plateau
Small adjustments to calories or activity usually restart progress.
Higher activity levels increase:
daily calorie burn
maintenance calories
potential fat loss speed
Even small increases in movement can make a difference.
Faster weight loss can:
increase fatigue
reduce muscle mass
be harder to maintain
Slower, steady progress is usually more sustainable.
Yes, if:
your activity increases
your metabolism adapts
your overall balance stays in a deficit
Calories are relative to what your body burns.
Hunger can increase due to:
reduced calorie intake
hormonal changes
food choices
Choosing higher protein and fibre foods can help manage this.
Metabolic adaptation is when your body:
burns fewer calories
becomes more efficient
This is a normal response during weight loss.
True fat gain in a deficit is extremely unlikely.
However, temporary weight gain can happen due to:
water retention
inflammation
digestion
Consistency matters more than perfection.
Being accurate most of the time is enough to see progress.
The best diet is one you can stick to.
Most effective approaches focus on:
whole foods
high protein
balanced meals
No, occasional higher calorie days do not ruin progress.
What matters is your average intake over time.
You’ll know it’s working if:
weight trends downward over time
measurements improve
consistency is maintained
Yes.
Weight loss is driven by calorie intake, but exercise helps improve:
health
body composition
sustainability
Perfect numbers don’t matter if they’re not followed.
Consistent habits produce better long-term results than short-term precision.
Your daily calorie needs depend on your:
weight
height
age
activity level
Most adults fall somewhere between 1,800 and 2,500 calories per day, but your personal maintenance calories can be higher or lower depending on your lifestyle.
To lose weight, you need to eat fewer calories than your body burns.
Most people see steady results with a 300–700 calorie deficit per day, which typically leads to around 0.25–0.75 kg of weight loss per week.
Y
our exact number depends on your body, activity level, and starting weight, which is why using a personalised calorie calculator is more accurate than guessing.
Maintenance calories are the number of calories your body needs to stay at the same weight.
If you eat this amount consistently:
your weight stays stable
you are not in a deficit or surplus
This calculator works out your maintenance calories first, then adjusts them depending on your goal.
For some people, yes but not for everyone.
Smaller or less active individuals may find 1500 calories suitable
Larger or more active individuals usually need more
Eating too few calories can lead to low energy, fatigue, and slower long-term progress.
On average, around 7,700 calories equals 1 kg of body fat.
That means:
500 calorie deficit per day ≈ 0.5 kg per week
300 calorie deficit per day ≈ 0.25 kg per week
Actual results can vary due to water weight, metabolism, and consistency.
A calorie calculator provides a strong starting estimate, but it isn’t exact.
Your real results can vary depending on:
metabolism
daily movement
consistency
tracking accuracy
The best approach is to use your result as a guide and adjust based on progress.
Weight loss is not perfectly linear.
Over time:
your metabolism adapts
your body burns fewer calories
progress naturally slows
This is normal and doesn’t mean the calculator is wrong, it just reflects how the body works.
This depends on your calorie deficit and starting point.
Most people can expect:
noticeable changes in 3–6 weeks
more visible results in 6–8 weeks
Consistency is the biggest factor.
You don’t have to, but it helps.
Tracking calories:
improves accuracy
helps you stay consistent
makes progress easier to manage
Even short-term tracking can make a big difference.
Yes.
If your goal is muscle gain, the calculator sets your calories slightly above maintenance to create a controlled surplus, which helps support muscle growth while limiting fat gain.
The number of calories you should eat to lose 5kg depends on your age, weight, height, activity level, and metabolism. To lose 5kg, you generally need to create a total calorie deficit of approximately 38,500 calories. Many people achieve this by maintaining a daily calorie deficit of 300 to 750 calories, which can result in steady and sustainable weight loss. Using a calorie calculator can help estimate a personalised calorie target based on your current body weight and weight loss goals.
To lose 10kg, your body needs to create an approximate calorie deficit of 77,000 calories over time. The exact number of calories you should eat each day depends on your maintenance calorie needs. For many people, reducing calorie intake by 500 calories per day can lead to gradual and sustainable weight loss. A personalised calorie calculator can estimate how many calories you should consume daily based on your weight, activity level, and desired rate of progress.
For most people, a daily calorie deficit of 300 to 500 calories is considered a realistic and sustainable approach to weight loss. This often results in losing around 0.25kg to 0.5kg per week while helping to maintain energy levels and muscle mass. Larger calorie deficits may produce faster results, but they can also increase hunger and make long-term consistency more difficult. The best calorie deficit is one that allows you to make steady progress while remaining manageable and sustainable over time.
