How is food intake regulated?
Eating is often a matter of hunger, nausea or gluttony. Unlike other essential functions such as breathing, eating is a one-time activity that we feel we have conscious control over and which can give us pleasure. Consumption of food provides the energy necessary for the body to function. It is regulated by numerous signals, sent by the brain , which act on the desire or need to eat.
Hunger is a physiological need that results in a feeling of empty stomach and hollowness. It initiates a meal and is most often combined with appetite. Unlike hunger, appetite is not a physiological need, it corresponds to the desire to eat a popular food or group of foods. Satiety and satiety respectively initiate the cessation of food intake and inhibit feelings of hunger during the day.
Food intake is partly regulated by a complex hormonal and peptide system. Depending on the presence or absence of food in the stomach, the brain will release orexigenic factors which stimulate appetite, or anorexigenic factors which inhibit hunger. It is thanks to its mediators that the digestive system and the brain communicate.
Sensory signals such as taste, appearance and texture of food make us salivate and also affect food intake. Be careful of foods that are sweet and high in fat, with creamy and smooth textures that are often very high in calories, which can encourage overconsumption of food .
It is not always easy to identify the signals of hunger and satiety, but it is very easy to be tempted by gluttony. Indeed, food restriction can be unbalanced by the search for food pleasure and gluttony . This food pleasure is linked to the release of the happiness hormone, which leads to temptation and the surpassing of the body's internal needs. The feeling of hunger has been replaced by the desire to eat : we then eat without hunger. The feeling of satiety is no longer controlled and the brain is unable to regulate the feeling of hunger. As a result, snacking is common.
In general, it is recommended to eat mindfully , that is to say, to be more attentive to our feelings of hunger and satiety, to take your time by eating calmly and at regular times. Lack of attention would be responsible for overconsumption of food. To combat cravings and snacking urges, you can consume an effective and natural appetite suppressant that increases satiety and delays the reappearance of the feeling of hunger.
