Gained a Few Pounds? Find the Culprit with our Weight Loss Calculator & Weight Chart

Use our Diet Doc weight loss calculator & ideal weight chart to estimate your caloric and exercise needs to reach your goal weight.

  • The weight loss calculator will help you determine what your daily calorie needs will look like based on your goal weight and time frame for achieving your goal weight.
  • The ideal weight chart will help you determine a range of healthy weights according to your height and skeletal frame.

The weight loss chart and calculator are for estimation only; everyone’s body reacts differently to weight loss programs based on factors such as:

  1. Diet – The quantity and quality of food in your diet have the most direct effect on weight gain and weight loss.
  2. Physical Activity Level – Frequency and intensity of exercise cause your body to burn more calories, including those stored as fat, to provide energy for activity
  3. Genetics – Genetic information is part of what governs the rate at which you will store fat and where it tends to be stored.
  4. Sleep – Sleep deprivation accelerates weight gain through various modes such as the induction of stress, which raises cortisol levels and, consequently, the rate of fat storage.

You can harness the power of our ideal weight chart and weight loss goal calculator by including it in your diet, exercise, and medical weight loss plan.

How to Use the Weight Loss Calculator:

First, check our chart of ideal weight according to height. Because ideal weights are in a range, round your height down if you are between two heights for best results.

Second, determine your weight loss time frame. Set realistic goals for weight loss; choose a time frame that does not compromise your health or raise your risk of cardiovascular disease.

Third, fill in the information in each field of our weight loss plan calculator.


Enter your current age into this field. Age affects your metabolism, so inputting an accurate age will help determine how you need to shape your diet and exercise plan according to how active your metabolism is.


Larger skeletons need more energy to perform all activities. Input your height to help discover calorie counts that will maintain your weight loss without exhausting your body.


Enter your starting weight here. It’s a jumping-off point for your weight loss goals. An accurate starting weight will help calculate the ideal calorie intake for maximum safe weight loss.

Weight Loss Time Frame

Input the amount of time within which you would like to meet or exceed your weight loss goals. Give yourself plenty of time to meet these goals; weight loss that is too rapid can negatively impact your health.

Weight Loss Goal

Type in your ideal weight according to the ideal weight chart. If you plan to go below ideal weight, ensure that you also plan to maintain a healthy body fat percentage and that you encourage the growth of skeletal muscle.
