weight loss calculator

To lose weight, you need follow a formula: take in fewer calories each day than you burn off with activity. In general, the established formula is that you’d have to consume 3,500 fewer calories, or burn off an extra 3,500 calories each week to lose one pound. However, everyone’s body is different, and each person has a unique metabolism and calorie requirement.

A weight loss calculator is a digital tool that can help you reach your weight loss goals. Typically with online weight loss calculators, you enter your height, weight, age, activity level, and the amount of weight you would like to lose. Then, the weight loss calculator figures out how many fewer calories you need to eat each day to reach your target weight, and how long it will take you to achieve that weight.

Some weight loss calculators give you different daily calorie options, so you can fine-tune your diet. Yet they typically will not go below 1,200 daily calories for women, and 1,500 calories for men, because anything lower would be too restrictive and wouldn’t be healthy.

Several commercial weight loss calculators are available online. The National Institutes of Health also offers its own Body Weight Planner. It was created by mathematician Kevin Hall, PhD, after he analyzed a number of weight-loss studies to find the factors that had the greatest effect on weight loss. To use the NIH calculator, you input your weight, gender, age, height, and physical activity level. Then, you input your goal weight, and the date by which you’d like to reach it. And, you indicate how much you’re willing to increase your activity level. The weight loss calculator tells you how many calories you need to trim to reach your goal weight within your ideal time frame.

Any weight loss calculator can help you trim down if you carefully follow the daily calorie recommendations. Using a calorie counter along with it can help you keep track of the number of calories you eat, and burn, each day.
