To lose weight, you need to eat fewer calories than you burn. In theory, this sounds simple. However, calorie counting is one way to tackle this problem.
A calorie is a measure of energy. In science, it’s defined as the amount of energy required to raise the temperature of 1 kilogram of water by 1 degree Celsius.
When you eat more calories than you burn, you gain weight. Counting calories can help you eat fewer calories and lose weight.
The exact amount of calories you need will depend on a number of different factors, including your gender, age, weight and activity levels. Use the calculator above to work out your daily requirement.
Using an app or online tool to record your meals and track your food intake is a very easy way to count calories.
You can use scales, cups and measures or portion-size estimates to determine how much you’re eating. Scales are the most accurate.
Basing your diet on minimally processed foods is beneficial for long-term health and weight loss.
Aim for slow and steady weight loss, and make sure you have a plan. Reading food labels and keeping less junk food in the house can also be helpful for success.
