The feeling of fullness stimulates a signal to the brain that tells us to stop eating. Satiety is the feeling of satisfaction, or not being hungry, that lasts long after that initial feeling of fullness has subsided. Satiety is the sensation that keeps us from snacking between meals. The feeling of satiety involves a number of natural physiological actions that start in the stomach and ultimately affect the appetite center in the brain.

The presence of food in the stomach stimulates the release of special proteins in the digestive tract. First they close the valve leading from the stomach into the intestine. This slows the digestion of food, giving us a feeling of fullness and extinguishing the drive to eat.

The second action initiated by the feel-full proteins is to send a signal to the appetite center in the brain. This also tells us to stop eating, but, more importantly, it is responsible for the extended feeling of fullness that occurs between meals.

Not all nutrients produce the same degree of satiety. Certain types of fat are the most effective, specific types of proteins are second, and carbohydrate has the least effect. Healthy satiety is the selective ingestion of those nutrients, either before a meal or with a meal that will maximize the overall satisfaction you get from the meal.

The initial research on the biology of satiety was conducted at Columbia and Cornell Universities almost 40 years ago. Additional studies have shown how CCK is released and how it works. Although many large drug companies have intense research efforts to develop drugs that stimulate the feel-full proteins, some of the latest research shows that consuming the right types of nutrients at the right time is also effective.

These discoveries open up enormous possibilities in terms of helping people lose weight and maintain a healthy weight. There are two primary dietary practices that promote healthy satiety. With the increased prevalence of energy-dense processed foods, the availability of eat-and-go restaurants, and busy lifestyles, most Americans consume meals in a very short period of time.

A meal at a fast food restaurant, which can be as much as 1, calories, can be consumed in five minutes. Healthy satiety involves changing your meal pattern to turn on your appetite control mechanisms before you eat your meal. Search Jobs.

Protein Eating foods that satisfy hunger and promote fullness can help control overall calorie consumption and reduce snacking between meals.

Published February 1, - More info. We examined the effect of intravenously infused glucagon-like peptide 1 GLP-1 on subjective appetite sensations after an energy-fixed breakfast, and on spontaneous energy intake at an ad libitum lunch.

h or saline was started simultaneously with initiation of the test meals. Visual analogue scales were used to assess appetite sensations throughout the experiment and the palatability of the test meals. Blood was sampled throughout the day for analysis of plasma hormone and substrate levels.

In conclusion, the results show that GLP-1 enhanced satiety and reduced energy intake and thus may play a physiological regulatory role in controlling appetite and energy intake in humans.
