Calorie counting

-

 You may have heard a lot about tracking what you eat and counting calories.Find out what calories are, the recommended intake, why it can be useful to count calories and how doing so can help you lose weight.

What are calories?
Calories are a measure of the amount of energy in an item of food or drink. You will see the number of calories in an item listed on the packaging as "kcal".

Should I keep track of calories?
When we eat and drink more calories than we use, our bodies store the excess as body fat. If this continues over time, we may put on weight.

Knowing the calorie content of food and drink – and how much we have – makes it easier to keep track of our daily intake.

However, counting calories is not the only way to change how you eat to lose weight. Simple things like adjusting portion sizes and making sure your meals are made up of the right types of food can also make a big difference.

How to count calories

Being really precise with calorie counting can be a little tricky, but there are some general guidelines that can be useful if you want to have a better idea about how many calories you're having each day.

Here are some simple ways to help you keep track.

Check the labels on shop-bought foods

You can find calorie information on food labels, usually broken down per portion, per 100g and per pack.

Per-portion information may be more useful than per 100g, but remember that the portion size you're having might not be the same as the manufacturer's portion – this can make a big difference to your calorie intake over the day.

Try weighing your portions

To begin with, it may be useful to weigh the portions you have. This should start to give you an idea of how many calories you are having and whether you need to adjust your portion size.

Keep a food diary

Having a daily record of everything you eat and drink can make it a lot easier to keep track of your calorie intake. Try it for a week or 2 to get a good idea of how many calories you're consuming and continue to keep a food diary if you find it useful.

Remember to include the calories in:

  • the oil and spreads you have cooked with
  • any toppings or accompaniments, like cheese or yoghurt
  • sauces, such as mayo and ketchup

The plan helps you control your blood sugar, also called blood glucose, manage your weight and control heart disease risk factors. These factors include high blood pressure and high blood fats. When you eat extra calories and carbohydrates, your blood sugar levels rise. If blood sugar isn't controlled, it can lead to serious problems. These problems include a high blood sugar level, called hyperglycemia. If this high level lasts for a long time, it may lead to long-term complications, such as nerve, kidney and heart damage. You can help keep your blood sugar level in a safe range. Make healthy food choices and track your eating habits.

 NATIONAL TASK FORCE ON THE PREVENTION AND TREATMENT OF OBESITY More than 60 percent of adults in the United States are overweight or obese, and obese persons are more likely to be ill than those who are not. Obesity presents challenges to physicians and patients and also has a negative impact on health status. Some patients who are obese may delay medical care because of concerns about disparagement by physicians and health care staff, or fear of being weighed. Simple accommodations, such as providing large-sized examination gowns and armless chairs, as well as weighing patients in a private area, may make the medical setting more accessible and more comfortable for obese patients.
