Your senses of taste and smell help you in taking pleasure in your meal when you consume food. However, vision can assist in your eating habits. A study printed in the journal Obesity Research by investigators in Stockholm, Sweden exhibits how vision influences your eating behavior.

The study comprised of 9 sightless and 9 seeing individuals, where both groups were given food to eat. The researches measured the volume of food ingested by each person, along with the subjects' perception of satisfaction. Later, the eating pattern of the seeing individuals were measured. However, on a second assessment, the seeing participants were blindfolded.

In general, the blind subjects had similar eating practices compared with the individuals who were seeing. Anyhow, when the sighted people were blindfolded, they ingested approximately 22% less food and occupied fewer moments eating compared to when they could see their meal. The seeing analysis individuals provided details of similar feelings of fullness for both meals.

The study analysts concluded that ingesting food while blindfolded may have brought about the individuals to listen to their innermost signals of hunger.

The sensory-specific satiety aspect could be a reason for a decline in food intake. Sensory-specific satiety refers to an increase of food intake when numerous dishes are served with varying nutritional and sensory qualities, compared with a situation with only one or a few food components. Sensory-specific satiety also occurs for the visual appearance of food, for example, color and shape. As an example, individuals ate about 14% more pasta with three various color and shapes, compared to pasta with the same color and shape.

Probably vision contributes to the satiating power of foods. We have familiarity of how satisfying some foods are and and decide how it will gratify us by designing our meal plan. Vision may stimulate us but also afford to satiety awareness that discontinue food consumption.

Gastric inflation and excretion of intestinal peptides are internal determinants which help in eating cessation. What we see is an external determinant that could also alter neural brain mechanisms involved in the eating cessation. Insulin release, salivation, and gastric acid secretion is a phenomenon in the cephalic phase of digestion which causes the body to respond to the sight and smell of food. Without seeing what we eat, therefore, may influence the cephalic state, which consequently, can affect the need to stop eating and the feeling of satisfaction when the meal is over.

Derived from this investigation, it can be determined that you can be trained to rely on your internal hunger cues. In summary, this research establishes the value of visual cues to manage intake of foods. Without making the subjects feel less full when their intake of food was decreased while they were blind folded.

Manipulation of the visual signals of food might be used for more detailed studies on eating behavior and may provide new approaches for the treatment of obesity.

Instead of reading or watching television while you consume your meals, focus solely on your food. Taste the unique flavors of each dish, and be aware of feelings of fullness, breaking off when you are full but not stuffed.
