Why do we eat junk food?

    Junk food, nutritionists say, encourages people to eat, thus increasing the risk of gaining weight and many other problems. There are a lot of studies on the subject why we prefer certain foods than the other.

    I will give you a few facts about why do you love to eat junk food…

    There are two factors that make us feel satisfaction when we eat tasty food.

    First of them is the taste and the smell of the food. Companies engaged in the production of junk food are spending millions to discover what taste customers enjoy the most and then work to create that taste. When you eat these foods, your brain responds nicely to it and you feel comfortable.

    Second factor are the nutrients that are included in the junk food – mixture of the proteins, fat and carbohydrates. Junk food producers are looking for the perfect mixture of the salt, sugar and fat that will excite your brain and make it crave for more.

    Is there a scientific explanation? Yes…

    Dynamical contrast

    It means combining different feelings by eating same food. Foods that have dynamical contrast are pizza or “Cream Brulee”. Your brain is excited when eating these foods, because it feels like eating something new with the each bite.

    Melting in your mouth

    Foods that melt and dissolve in your mouth fast, are sending a signal to your brain that you are not eating enough. That is the reason why you overeat when you eat the junk food.

    Response of the sensors

    Your delusional brain likes diversity. If you eat the same foods all the time, you will stop enjoying them. This is because sensors in your brain will stop responding to that food. Junk food is made to be tasty enough, so your brain sensors always respond to it.


    Salvation is one of the eating processes. Some foods like mayo, salad dressings, chocolate or butter provoke intense salvation and creates a feeling that what you eat is tastier than it actually is. That is why you enjoy glazed food.

    Calorie density

    Junk food is designed to convince your brain that your body is getting enough nutrients, but does not make you feel full. It provides a plenty of calories and because of that the brain has the impression that these food is giving your body enough energy. But still, it does not have as many calories as you think, and that is why you need a lot of junk food until you’re full.


    If you haven’t hear so far, let me open your eyes; sugar not only spoils your teeth and affects the obesity, but it is also guilty for dementia and liver problems; table salt or sodium chloride, is one of the main reasons for your high blood pressure; junk or process food is full of additives that can cause major problems like headaches, allergies, digestion problems, inflammatory diseases or, even, cancer.

    Can you exclude junk food from your diet and how? The less junk food you eat, the less your organism will crave for it.

    Eat variety of foods

    I have already explained to you that your brain likes new things. Thus, you have to eat different food that is going to be interesting to your brain. If you don’t have enough time to prepare different healthy foods all the time, you can always try with the supplements as a healthy substitute or an addition to your meal. There are a lot of them on the market like Legion athletics, ultimate nutrition, various energy pills or any other that you can find. Never mind what will you choose it is certainly better than the junk you have been eating so far.


    Find a better way to deal with stress

    Stress causes the secretion of certain chemicals in the brain that are similar to the chemicals that cause hunger for fat and sugar. In other words, when you are under stress, the brain has a greater desire for fat and sugar, and causes you to eat junk food. Find a way to cope with stress. Meditate, exercise, draw, write, do anything which will help you to relax.


    I’m sure that most of you are aware of the fact that the junk food is not healthy. You know that it causes heart problems, high blood pressure and many other health problems. Ask yourself is there a rational reason to continue with this kind of diet?
