When tasting a lite snack, the body prepares to receive a lot of calories, but ends up running on very little – and this causes confusion and makes it seek more food.

This finding partly explains why obesity is still spreading in the Western world, despite the extensive use of  lite foods by millions of people worldwide.

The substitution of part of the food with foods that have similar taste but fewer or zero calories, looks like a very sensible approach to weight loss.

However, many different biological mechanisms are factored in. These substituents mimic the taste of fat, but do not provide calories – and this causes confusion in the body.

The various flavors naturally stimulate your body to expect to be supplied with calories, which it will then digest.

When this does not happen, the body perceives it as a problem of the control mechanism of food intake and activates other mechanisms to compensate for this dysfunction.

Researchers studied the variations in body weight in a group of rats. Half the animals ate full-fat bread sticks for 28 days, while the rest ate normal breadsticks for a few days and then began to feed on the lite version. At the end of four weeks, the rats that had changed diet weighed more and had more body fat than than those who ate low fat bread sticks until the end of the study.

The researchers noted that even though this study was done in animal models, there are many similarities with humans. The findings call into question the effectiveness of using fat substitutes in a long-term strategic control of body weight.

When we go through a phase of feeling down one of our first reactions is to start eating. Sometimes what we eat is bad for our health and gives us extra pounds. Talking with friends or a specialist can help us to overcome clinical depression, but there are three things that affect our eating habits.

Many of you crave carbohydrates or sweets like cakes and ice cream when you feel stress and unhappiness. Consumption of foods high in sugar can make you feel calm in the short-term, but such a diet in the long term can result in excess weight and increased risk of heart disease, diabetes and other serious health problems.

When you are not feeling well, it is possible to lose your appetite. The starvation, however, can make you more irritable and sensitive, which worsens your depression.

Those who suffer from depression often eat junk food or sometimes the same food over and over. This is because usually people who have signs of depression, have difficulties in concentration, memory and decision making. This can make simple tasks seem overwhelming and you may end up eating the same three meals in a day.

First, you should consult a specialist who will be your best friend in this stage of your life. Once the symptoms of depression begin to subside, we have prepared some tips that you should definitely follow.

First of all you should make sure you are really hungry and not eat from boredom. Secondly you should include in your diet vegetables and fruits. Third, the daily exercise will help you a lot to come back to your pace.

If you keep all this be sure that even if the depression returns, you can eliminate it if you really want.
