Maintenance calories are calculated using the Mifflin-St Jeor BMR formula. Activity multipliers and calorie surplus guidance are based on the Dietary Reference Intakes (National Academies Press, 2006) and Iraki et al., Sports (2019). These are estimates only—not medical advice. Please consult a doctor or dietitian before starting a weight-gain plan.

Weight Gain Calculator

A Weight Gain Calculator is a tool that assists people in calculating the estimated amount of daily calories required to reach their desired weight. The calories may vary from individual to individual based on factors such as height, weight, age, gender, and activity level. The Weight Gain Calorie Calculator suggests consuming more calories than you burn to help in weight gain. This is done by calculating the BMR & TDEE.

Basal Metabolic Rate (BMR) is the minimum rate of calories burned even while the body is at rest. It is required to maintain essential body functions like breathing, blood circulation, and body temperature.

Total Daily Energy Expenditure (TDEE) is the amount of calories burnt by the body per day while taking into account all the activities done daily. This is estimated by multiplying BMR and the activity level factor, which is why it varies for persons performing different levels of physical activity.

From TDEE, and with the help of a weight gain calorie calculator,  you can determine the required daily calorie surplus for weight gain.

How to Use the Calculator

  • Enter Your Details: Enter personal details such as age, gender, height (in cm), weight (in kg), and physical activity level (based on your lifestyle) in the Weight Gain Calorie Calculator.
  • Calculate Your Calorie Goal: This Weight Gain Calculator will help calculate your BMR and TDEE to establish your maintenance calories.
  • Create a Calorie Surplus: Increase your calorie consumption to create a calorie surplus above your maintenance calories for weight gain.
  • Consistency: Make sure you meet your daily calorie goals through proper nutrition and monitor your progress.

Healthy Tips for Weight Gain

  • Consume Surplus Calories: Increase your calorie intake by consuming more calories than you burn to gain weight in a healthy way.
  • Eat Calorie-Dense Foods: Incorporate calorie-dense foods in your diet, such as whole grains, healthy fats, and lean proteins, which are also nutrient-dense.
  • Have Healthy Fats: Nuts, seeds, avocado, and olive oil provide healthy fats for healthy weight gain. It is important to avoid excessive consumption of saturated and trans fats.
  • Increase Protein Intake: Ensure that you take enough protein for muscle growth and maintenance.
  • Follow a Consistent Meal Pattern: Have meals at regular times and consistently consume surplus calories in small, frequent meals for steady weight gain.
  • Engage in Strength Training: Strength training ensures that the extra calories are utilised for building muscle rather than fat gain.

FAQs

Q.1 How many extra calories do you need for gaining weight?

Ans: You may require a modest increase of 300-500 calories per day apart from your daily requirement in order to gain weight in a healthy way. The calorie requirement may vary depending upon one’s metabolism and activity level.

Q2. How long will it take for me to notice any changes in my weight?

Ans: The time required to see visible weight gain varies from person to person. Visible results depend on multiple factors such as your daily calorie intake, diet quality, activity level, and metabolism.

Q3. Can I continue to exercise even while trying to gain weight with a calorie surplus?

Ans: Yes. Exercising while consuming a calorie surplus helps stimulate muscle protein synthesis and ensures that the extra calories are utilised to build lean muscle.

Q4. How is the Weight Gain Calorie Calculator different from a Protein Calculator?

Ans: The Weight Gain Calorie Calculator calculates your daily surplus calorie needs in order to gain weight depending on your weight gain target. The Protein Calculator calculates your daily protein needs as per your physical activity level.

Disclaimer: This calorie calculator provides only estimated calorie requirements that may vary for different individual needs. Do not consider these as exact values. It is always recommended to consult a healthcare professional for personalised guidance.
