Your Daily Calorie Target
Use this as a practical starting estimate, not a strict prescription.
Estimated daily planning range
— kcal/day
Based on your estimated maintenance calories and selected goal.
Additional food energy above maintenance
—
This is the additional daily energy built into the planning range.
Protein planning range for muscle building
—
Use this as a general planning range. A dietitian can tailor it around your training, health and food preferences.
Your Suggested Meal Budget
Use the calorie range as your daily guide, then divide it across meals in a way that fits your routine.
Example daily food budget
—kcal/day
This example uses the midpoint of your planning range. You can move calories between meals while keeping the daily total as the main guide.
About 25% of the example daily budget.
About 30% of the example daily budget.
About 30% of the example daily budget.
About 15% of the example daily budget.
The split is an example, not a prescribed menu. Food calories vary by portion size, brand and cooking method.
Recommended Activity Focus for Muscle Building
Prioritise resistance training for muscle development. Cardio and mobility support fitness and recovery; they are not calorie-burn targets you need to offset with more food.
Use major movement patterns such as squats, presses, rows, hinges and pulls. Progress gradually over time.
A practical alternative or supplement when you do not have access to gym equipment.
Walking, cycling or easy swimming can support cardiovascular fitness without making calorie burn the main goal.
Mobility, stretching or easy yoga can support movement quality and recovery between harder sessions.
If you are new to resistance training, start with fewer sessions and build gradually. Exercise selection and progression should match your experience, injuries and health conditions.

Your estimated plan
Your Daily Action Plan
See how much to eat, how much extra activity to burn, and how those numbers add up to your selected weight goal.
What To Do Each Day
Start with the two daily numbers you can act on: your maximum daily calorie intake and the extra calories you plan to burn through activity.
—% food + —% activity
Maximum Daily Calorie Intake
—kcal/day
This is your maximum daily calorie intake per day, based on your selected plan.
Daily Calorie Burn Target
—kcal/day
This is the daily calorie amount you need to burn through extra activity per day, based on your selected plan.
How Your Daily Numbers Work Together
Your food target and activity target are two separate actions. Do not subtract your activity calories from your food allowance again.

Food calories are approximate examples and vary by brand, portion size and cooking method. Use the meal budget as the main guide.
These are practical calorie budgets, not strict meal limits or a prescribed menu. You can redistribute calories between meals while keeping the daily total as the main guide.
This is a planning estimate, not a fixed prescription. Actual weight change is not perfectly linear, and energy needs can change as your weight, activity and routine change.

Your Planned Extra Activity
See which activities contribute most to your weekly burn instead of reading one combined number.
Your planned extra activity
—kcal/day avg
We’ll compare your selected sessions with the activity share in your calorie-gap plan.
How the estimates are calculated
The planner uses the Mifflin–St Jeor equation to estimate resting energy needs and applies your selected usual-activity factor to estimate maintenance calories. The target timeline is converted into a planning calorie gap, then split between food and extra activity according to the percentage you chose.
Activity burn uses MET values, body weight, intensity, session duration and days per week. Weekly exercise calories are divided by seven to show an average daily contribution. Actual burn varies with pace, fitness, body composition, terrain and technique.

For adults 18+. This general tool is not intended for pregnancy or breastfeeding, eating-disorder management, or personalised medical nutrition treatment. If you have a medical condition, take medicines that affect weight or exercise tolerance, or the suggested calorie gap feels difficult to sustain, speak with a healthcare professional or dietitian.

Calorie Calculator Malaysia & Weight Goal Planner
This calculator helps adults estimate maintenance calories and build goal-specific guidance for weight loss, weight maintenance, weight gain, muscle building or overall health. It combines calorie targets, practical meal budgets and, where relevant, weight-loss activity planning or muscle-building training guidance in one tool.
Understand your maintenance calories
See how your age, gender, height, weight and usual activity shape the estimate.
Match calories to your goal
See a goal-specific calorie range for maintenance, weight gain or muscle building, or build a target-weight timeline for weight loss.
Turn the result into practical actions
Weight loss can expand into a flexible weekly activity plan, while muscle building adds resistance-training and recovery guidance.
Calorie & Weight Goal Calculator FAQ
What is a calorie gap or calorie deficit?
A calorie gap is the difference between the calories your body uses and the calories you take in. In this planner, the estimated gap can be shared between eating fewer calories and doing extra activity.
How does this calculator estimate how many calories I burn?
The planner estimates resting energy needs using the Mifflin–St Jeor equation, then applies your selected usual-activity level to estimate maintenance calories. Exercise calories are estimated separately from activity type, intensity, body weight, session duration and weekly frequency.
Do I need to exercise every day?
No. You can choose how many days per week you plan to do each activity. The calculator converts your weekly exercise into an average daily contribution so different routines can be compared with your daily calorie-gap target.
Can I combine more than one type of exercise?
Yes. You can mix multiple activities and adjust the intensity, minutes per session and days per week for each one.
Does the calculator also work for weight gain and muscle building?
Yes. Weight-gain results include a calorie surplus and meal budget. Muscle-building results also include a protein planning range and resistance-training guidance, rather than treating exercise as calories that must be burned.
Why does the meal budget show breakfast, lunch, dinner and a snack?
The meal split is a practical example to make the daily calorie target easier to picture. It is not a prescribed menu, and calories can be moved between meals while keeping the daily total as the main guide.
Why does the planner sometimes suggest a longer timeline?
If the selected goal requires a very large calorie gap or implies an unusually low food intake, the planner flags the timeline and suggests extending it rather than presenting the result as a recommended eating target.
