If you are thinking about going on a diet, there are several things that you should consider. One of the most important aspects of a healthy weight-loss diet is the number of calories taken in each day. The average human consumes approximately 2000 calories, which is a good estimate of the energy requirement for an active lifestyle. However, if you do not have this lifestyle it will be necessary to reduce your calorie intake to compensate for the energy that your body does not use. A good starting point may be a 1500 calorie diet, which is a number that provides a reasonable step down from the typical value.
To achieve this, you essentially have two options. You may reduce the quantity of food that you eat, which can be difficult for someone that is used to eating a regularly-sized meal. A better alternative is to force yourself to eat foods that are low in energy density. Soup is one example of this type of food, as are vegetables and fruits. The typical number of calories in a banana is about 105. For this volume of food, this is a relatively low density – a burger of similar volume often contains upwards of 300 calories!
Eating foods that are low in energy density is a way of tricking your body into thinking that it has had a full meal. The extra volume from these foods causes your stomach to expand, which gives you the feeling of being full. This makes it easier for you to say no to extra food that you have restricted yourself from eating, and has the added benefit of introducing a healthy balance of vitamins and minerals into your diet.
