What is a calorie deficit?

Creating a calorie deficit is at the core of weight loss. A calorie deficit is when you burn more calories than you take in. Researchers believe that to lose weight and maintain that loss in the long run, you must strike a balance between calories in and calories out.

Weight Watchers offers a comprehensive approach to weight loss that can help you reach your goals.

A calorie deficit is the difference between calories consumed and calories burned. Anything you eat and drink will be calories consumed. The body burns calories each day moving around, digesting food and other normal activities. Increase your calories burned by adding exercise. Aim for a deficit of 500 calories/day or 3500/week to lose 1 pound.

A calorie deficit is the difference between the calories you consume (food, drinks) and the calories that you burn (during activity, and during exercise). To lose 1 pound you need to have a 3500 calorie deficit (500 calories/day less consumption than you burn).
A calorie deficit is the difference between the daily amount of calories your body needs to survive, and the calories you burn.
For example, if your body burns 2,000 calories a day, and you only eat 1,500 calories worth of food, you have created a calorie deficit of 500 calories.
In order to lose weight, you must create a calorie deficit either by eating less than what your body burns, or exercising more to create a calorie deficit through exercise.
