How easy was it to use our calculator? Did you face any problem, tell us!

Weight loss calculator helps you to estimate how many calories you should have to eat to lose weight and even helps to plan your healthy goals.

No doubt, putting on weight is easier than getting rid of extra pounds. Weight loss is not as easy as you seem, it requires consistent effort. However, the exact amount of calorie intake can result in losing extra weight (pound/kg).

How Many Calories Do You Need To Lose Weight?

If your goal comes up with losing weight at a normal pace, then you need to eliminate 500-1000 calories from your daily diet intake. You better keep in mind that:

  • To lose 1 pound of weight, you need to burn about 3,500 calories count in a week
  • Losing 0.5 pound needs you to burn about 1750 calories in a week
  • If you want to limit yourself to 0.25 lbs, 875 are your calories needed to lose weight

Nutritionist experts do not permit limiting your caloric intake by more than 1000 per day. If you do this, your muscle mass will start decreasing rapidly. This will decrease your BMR and you will lose weight more while being unhealthy. So never aim to lose more than 2 pounds a week.

Science Behind The Weight Loss & Calories:

The science entails that you should eat less calories than you expend. When you do this, your body will start consuming energy from the fat stored in it. It will lead to losing excess flab from the body, thereby assisting in healthy weight loss without any health issues.

How To Calculate Weight Loss Calories?

Your weight loss calories calculations depend upon total daily energy expenditure and BMR.

BMR contributes to 70% of your daily calorie needs. This is why it provides a baseline to estimate calories per day to lose weight.

The calorie calculator for weight loss is based on the same theory and considers 3 equations that give you an average estimation of your BMR calories. These include:

Mifflin-St Jeor Equation:

BMR = (10.m + 6.25h โ€“ 5.0a) + s
m = Mass (kg), h = Height (cm), a = Age (years), s = +5 for males, -151 for females

The gender specific versions of this formulas are as under:

Men: 10 x weight (kg) + 6.25 x height (cm) โ€“ 5 x age (y) + 5
Women: 10 x weight (kg) + 6.25 x height (cm) โ€“ 5 x age (y) โ€“ 161

Katch-McArdle Equation:

Katch = 370 + (21.6 * LBM)
LBM = lean body mass

Revised Harris-Benedict Equation:

MEN: (13.397m + 4.799h โ€“ 5.677a) + 88.362
WOMEN: Harris-Benedict = (9.247m + 3.098h โ€“ 4.330a) + 447.593
m = Mass (kg), h = Height (cm), a = Age (years)

These equations provide calories that you need to eat to maintain your weight while at rest.

Your daily energy expenditure is an estimation of how many calories count you burn during a certain activity. Each activity has a specific metabolic equivalent of task (MET).

The calculator simplifies the process by categorizing activity levels into four distinct levels, each associated with specific MET values. These include:

Activity Level MET Value
No Sports/Exercise 0.2
Light Activity 1-3 Times per Week 0.375
Moderate Activity 3-5 Times per Week 0.55
High Activity Everyday Exercise 0.725
Extreme Activity Professional Athlete 0.9

MET values help gauge the intensity of your physical activities, thereby providing a convenient way to estimate your daily calorie expenditure.

Example:

Individual’s Details:

Weight (W) = 75 kilograms

Height (H) = 174 centimeters

Age (A) = 26 years

Body fat percentage (F) = 15%

Activity Level:

Moderate Active (Person exercises regularly (3-5 times per week)

Calculations:

Step # 01: BMR Estimation

Using Katch-McArdle Formula

BMR = 370 + 21.6(1 – F)W

BMR = 370 + 21.6(1 – 0.20) * 70

BMR = 370 + 21.6 (0.80) * 70

BMR = 370 + 1209.6

BMR = 1579.6 calories

Step # 02: Estimating TDEE with the activity level provided

Moderate Activity (MET) = 0.55

TDEE = BMR ร— MET

TDEE = 1579.6 ร— 0.55

TDEE = 868.78 calories

Step # 03: Daily Calorie Intake For Weight Loss

To lose weight healthily, you should cut off 500 calories from your daily intake. Considering this, we have:

Calorie Intake = TDEE – 500

Calorie Intake = 868.78 – 500

Calorie Intake = 368.78 calories

Final Verdict:

If the person wants to lose body fat without any health issues, he/she has to eat 368.78 calories less than his/her energy expenditure.

Zigzag Schedule For Calorie Intake:

This is an evident approach to losing weight by consuming calories in a zigzag manner. When you eat the same number of calories each day, a time will come when your body gets used to it. In this condition, the plateau of weight loss happens and your body does not lose more weight after a certain time. This is why you need to eat by changing your calorie number daily.

What You Should Do?

Suppose your fat loss calories counting are 2000 per day, then

  • You should eat 2300 calories in the first three days
  • For the remaining four days, eat 1775 calories

Following this practice will keep your total calorie ingestion 14000 weekly but in a more effective way. The combination of high and low-calorie consumption allows you to eat flexibly.

If you face difficulty in planning your calories this way, give zig zag diet calculator a try and get your personalized diet schedules for sustained weight loss straightaway in seconds. The tool gives you a couple of different plans that allow you to eat the way you want and lose weight accordingly.

How To Reduce Calories For Weight Loss?

Intermittent Fasting
Fasting strategically will help you to lose 0.55 to 1.65 pounds (0.25โ€“0.75 kg) per week. During fasting hours, your body is shifted to fat-burning mode and consumes energy from it. To lose weight fast, you should follow a 16:8 rule which means fasting for 16 hours and eating only 8 hours in a single day.
Regular Workout
Workout increases your physical activity level and it helps to reduce calories by burning them. Remember that exercising on a daily basis will improve your resting metabolic rate (RMR), build lean mass, help regulate stress, and support long-term weight maintenance. Combining diet with exercise is the most effective technique to lose weight.
Stop Drinking Your Calories
Never drink your calories as it can cause type 2 Diabetes and severe obesity. Intaking soda drinks not only increase your calorie consumption but will also increase your hunger later on. Cut back your sweetened drinks, limit your alcohol consumption, and sugar-enriched coffee, etc.
Make Food Swaps
Never stop eating the foods that you love and they are enriched in nutrients. You can eat them in a sufficient quantity that will make your diet enjoyable and deliver calories enough to lose weight. So keeping a balance between high-calorie and less nutritive foods will be a wise choice to lose fat.
Fill up with Water, Protein, and Fibre
A diet consisting of sufficient water, moderate protein, and a controlled amount of high-saturated carbohydrates will keep your stomach full while delivering fewer calories. Such a food will keep your digestive system active and support the maintenance of muscle during during weight loss. Protein takes a lot of time to digest properly and this is why you will feel full after eating it.
Reduce Portion Sizes
This is an effective approach to adopting a controlled calorie deficit. In the start, cut a smaller number of calories from your daily diet and then make arrangements to get far better results. According to the United States Department of Agriculture (USDA) and Food and Drug Administration (FDA), natives of the United States prefer eating a little bit larger portions than recommended by nutritionists.
