Weight Loss Calculator

Understanding weight loss means using a weight loss calculator whenever you want to find out how long you should stay on a diet or how much effort you should put into exercising to get to your ideal weight. If you don’t have any idea what a weight loss calculator does, it’s best to start with the variables included in the calculation of weight loss for a specific individual.


True weight loss is all about balancing your diet and your exercise. Using your diet, you can control how much calories you take in. Using exercise, you can control how much calories you burn up. Calories are values that should be a part of any weight loss calculator equation. The good thing is that every food item and diet food product around has a calorie count. If you know how much calories a grapefruit contains, you will be wiser about going for or rejecting a diet that involves eating a ton of grapefruit every week. Weight loss calculator equations always involve calories.

While there is no exact number of calorie consumption to lose weight, we can all go by the average values for an average person. An average person can lose weight by consuming less than two thousand calories, but the same amount may be too much or too little for someone who’s overweight or underweight. Hence, other factors involved in the calculation should be considered.

Basal Metabolic Rate

There are some weight loss calculators that include the basal metabolic rate of an individual in the equation. The BMR is also a value that represents the amount of energy the body requires to function at rest. An average person normally uses up 60% of the consumed calories to fuel the automatic processes of his body, like breathing during sleep.

Personal Stats and Physical Activity

Height, weight, age and gender are factors that affect weight loss calculation. These aspects are important because they directly affect the basal metabolic rate. There is a specific equation to calculate the basal metabolic rate for men and for women. The equation is called Harris-Benedict principle, which estimates the basal metabolic rate value. Most weight loss calculators only require you to put in your gender, height and current weight, as well as your own estimation of how intense your physical activity is daily. The only thing in this calculation that could be subjective is the activity level, which is graded by the individual itself. This means the system they use can automatically compute your basal metabolic rate and provide an accurate weight loss calculation for a specified duration.
