check food labels? they should list the number of calories in each serving
Energy balance is simply the relationship between your energy input and your energy output. The complete energy equation looks like this:
Energy balance = energy input – energy output
We input energy when we eat. The food we consume provides calories. Calories are simply a unit of energy or heat. The food we eat and the drinks we consume provide different amounts of energy. Protein and carbohydrate each provide 4 calories per gram, and fat provides 9 calories per gram.
So how do you know your energy input number? Count the number of calories you eat each day. You can do it with a simple downloadable food diary or you can use a popular calorie counting app. A typical woman may consume anywhere from 1200 to 2500 calories per day. That's a pretty big range. To get the most accurate number for you, track your calories for at least a week.
A positive energy balance occurs when your energy input is greater than your energy output. That is, you eat more calories than your body needs. Your body stores excess energy or calories as fat. This results in weight gain.
Weight gain = energy input > energy output
Weight loss occurs when you create a negative energy balance. That is, you burn more calories than you consume. When this imbalance occurs, your body burns stored energy (fat) in order to function and you lose weight. A negative energy balance is sometimes called a calorie deficit.
Weight loss = energy input < energy output
When you evaluate your own energy balance, it's best to get the numbers as accurate as possible. Small differences in energy input and energy output can make a big difference in your weight.
Hope this helps!!!
