The body has the ability to direct the amount of the food we eat on its own. In great part, the hormones ghrelin and leptin are responsible for this process.
For instance, when a person consumes sugar, the body builds a generation of leptin, which is the one that controls accumulation of fat and hunger. Om the other hand, ghrelin, also known as the “craving hormone”, as people given this hormone during a study done on ghrelin happened to be insatiable, although they ate more than their typical diet.
Ghrelin follows up on the cerebrum`s “pleasure focuses” and it basically forces the person to reach for another piece of cake due to the fact that he still has the taste of the previous bite on his mind.
Between the arrivals of the aforementioned hormones, the body is aware of the amount of food it needs and you stop eating. However, there are many components which may crash this framework.
When insulin is stopped, ghrelin levels stay high even after the consumption of a meal which is supposed to end the craving, usually carbs. This eventually leads to weight gain.
Your state of mind affects your food cravings as well as the junk foods whose ingredients make you eat even more.
‘Hunger Neurons’: Your Body Is Hard-Wired to Have a Negative Response to Hunger
When you are extremely hungry, the agouti-related protein- expression (AGRP) neurons trigger off-putting feelings in your body. This forces your body to look for foods which will put an end to these negative emotions.
Looking for your next feast puts you in an dangerous situation and your appetite neuron`s capacity to seek to obtain these negative emotions served as push to find food.
If certain food is highly accessible, it means that you will consume it all the time, mainly for the purpose of feeling better by quitting your AGRP neurons.
However, this is not so bad and the body should have this capacity to direct its nourishment, aside from the fact that this reaction is linked to positive reaction to junk food. This goes to show that junk food basically causes sort of addiction and weight gain.
Junk Foods Are Engineered to Be ‘Hyper-Rewarding’
Food producers have found a way to overturn the body`s inherent craving controllers by providing foods which are designed to be “hyper-rewarding”.
As shown by the “food reward theory of obesity” processed foods stimulate such solid prize reaction in our brains, which only serves as stimulation for indulgence and overeating. One of the directing standards for processed food industry is known as “sensory specific satiety”.
This is described as “the tendency for big, distinct flavors to overwhelm your brain” by Michael Moss, an investigative reporter.
The greatest “triumphs” of fast foods producers, whether they are drinks or junk food, is their “craveability” to complex formulas which irritate your taste buds, overriding your brain to say “it`s enough”.
Potato chips are the most addictive form of junk foods, containing each of the “bliss-inducing” ingredients: sugar, salt, and fat. Unfortunately, healthy foods like celery and other veggies don’t have such hyper-rewarding traits.
