How many calories should I eat to lose weight?

The Calorie calculator allows you to calculate how many calories you should eat a day in order to lose a certain amount of weight by a certain date.

For example: If you are 86kg (189.6Ibs) start of November and would like to be 78kg (172Ibs) by Christmas, you would specify that you want to lose 8 kilograms (17.6Ibs) in 2 months. This is how it differs to other calorie calculators which only allow you to calculate the amount of calories daily for a specific weight.

The calorie calculator is very useful for weight management as it displays how many calories are needed over the specified period of time. It keeps track of your weight loss and calories required. The less you weigh, the fewer calories you will need to take in for weight loss to continue.

NB: Any (-ve) negative values are shown in red, ie trying to lose 50 pounds in 1 week is not possible. Values in yellow indicates a very low calorie intake. As a rule of thumb you should not eat below 1200 calories for female and 1600 calories for male.
