Think you can't eat for satisfaction and a healthy body weight simultaneously? Think again!
Although
the U.S. population is obsessed with dieting, this obsession has not
translated into positive results. Obesity continues to increase among
all age groups and serial dieting is on the rise. The core of the
problem is our inability to stay on a diet until we reach our target
weight and then maintain it. Most weight-loss diets simply fail to
provide the satisfaction that we need and expect from food. Research at
leading obesity laboratories has started to focus on the disconnect
between dieting and food satisfaction in the hope of finding a solution
to help end diet failure. This research has identified a number of
proteins that are naturally released in the GI tract when we eat and
act in the appetite centers of the brain, where the feeling of
satisfaction or satiety is localized. The practical implications of
these exciting new findings form the basis of an exciting new concept
called healthy satiety.
Healthy
satiety is an innovative new eating strategy uses specific nutrients to
activate the body’s natural appetite control switch, thereby enabling
individuals to achieve greater satisfaction from their diet at a lower
calorie cost. These specific nutrients, which studies now show are
powerful controllers of appetite, have also been shown to provide
additional health benefits, including a reduction in cardiovascular
disease. Healthy satiety can be incorporated into any diet plan to
help individuals lose weight and, once they achieve their target
weight, to help them maintain it. Until now, healthy satiety was the
essential component missing in all diet plans.
The Science of Satiety
Although
satiety is often confused with fullness, there are important
differences between the two phenomena. Everyone is familiar with the
feeling of stomach fullness that is experienced after eating a
meal. Fullness is associated with a satisfied feeling in the stomach
or, if you overeat, an uncomfortable feeling. The feeling of fullness
stimulates a signal to the brain that tells us to stop eating. Foods
that are high in fiber can produce a feeling of fullness; however, they
are not effective in activating the “feel-full” proteins. Therefore,
whereas fiber may make you feel full, it won’t necessarily maintain
satiety for an extended period of time after you eat.
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. Scientists call them appetite
regulatory peptides, but you can think of them as “feel-full
proteins.” The release of these proteins initiates a number of
actions. 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. Scientists showed that
the body’s primary satiety peptide, cholecystokinin, or CCK, reduced
food intake and extended the feeling of fullness after a
meal. 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.
Two Steps to Healthy Satiety
There are two primary dietary practices that promote healthy satiety.
1. Turn on satiety before you eat
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 1,200 calories, can be
consumed in five minutes. Even though the body has a sophisticated
appetite control system, in today’s environment it kicks in too late,
since the food is already in the stomach. Healthy satiety involves
changing your meal pattern to turn on your appetite control mechanisms
before you eat your meal.
The
best way to do this is to consume foods that contain those nutrients
which are extremely effective in activating the feel-full proteins. The
fats that are most effective are called long-chain fatty acids. These
are also monounsaturated fats and are found in high concentrations in
corn oil, canola oil, olive oil, safflower oil, sunflower oil, peanut
oil and soybean oil. Although not as potent has the aforementioned
fats, certain proteins, especially soy and whey (a dairy protein), are
very effective. Consuming a small amount of foods rich in these
nutrients will release the feel full proteins before you start
eating. Thus, you will feel fuller even if you eat fewer calories. Here
are some high satiety appetizers. Because these oils are so effective
in turning off your appetite, you only need a small amount.
· ½ teaspoon peanut butter on a piece of celery
· 2 oz turkey on a cracker
· 1 oz mozzarella cheese on a cracker
· 2 oz tuna in one oz olive oil
2. Eat healthy, “satisfilling” meals
The
ideal type of meal to eat for healthy satiety provides maximum
satisfaction without too many calories. The term “Satisfilling” has
been used to describe this type of meal. A healthy, Satisfilling meal
has three components: at least one low-density food, at least one
high-satiety food, and a satiety activator.
Foods
are classified as “low energy density” when they contain a relatively
low concentration of calories. The least energy-dense foods are those
that contain a lot of fiber, which is found prevalently in fruits and
vegetables. Such foods help us eat less because they fill a lot of
space in the stomach with relatively few calories. If we combine these
foods with those that also have high satiating value we get the best of
both worlds – fullness and satiety – with fewer calories.
The
table below lists examples of low-density foods that provide fullness
and high-satiety foods that offer satiety. Adding a small amount of one
or more “satiety activators” to a meal combining low-density and
high-satiety foods will ensure maximum satisfaction in a calorically
efficient manner

Satisfilling meals should not include processed foods that contain high
amounts of saturated fats and sugars, which give you calories without
providing meal satisfaction (fullness plus satiety).
Secondary Steps to Healthy Satiety
In addition to the two primary steps to healthy satiety, there are three secondary steps.
1. Eat more frequent meals
The
more frequently you eat throughout the day, the less hunger and the
more satiety you will experience between meals. When you are less
hungry at the start of each meal, you will tend to eat less.
2. Don’t skip breakfast
When
you skip breakfast, you are usually extremely hungry later in the day,
and consequently eat much more. Eating breakfast results in a feeling
of satiety that causes you to eat less during the rest of the day. A
study published in the American Journal of Clinical Nutrition
found that women who ate breakfast voluntarily consumed roughly 100
fewer calories throughout the entire day than women who skipped
breakfast.
3. Avoid mindless eating
Another important step in practicing
healthy satiety is developing a better understanding of when you’re
really hungry and when you’re not, and training yourself to avoid
eating when you’re not hungry.
There are five types of “mindless eating” that you need to watch out for and avoid:
Emotional Eating:
Often the factor that drives our eating is not physical hunger but
emotions such as happiness, sadness, or even boredom. Learn to tell the
difference between real, physical hunger and emotional food cravings.
Spontaneous Eating:
Often we eat food just because it’s there, even when we’re already
full. This adds a lot of useless calories to one’s diet. The best way
to avoid spontaneous eating is to eat on a regular schedule.
Unconscious Eating: Sometimes
we eat without even being fully conscious that we are doing so (often
in front of the TV). Food journaling is a useful tool you can use to
steer clear of unconscious eating.
Habitual Eating:
Eating out of habit instead of hunger is known as habitual eating.
Eating on a schedule is a good thing if the schedule is sensible, but becomes a bad thing when the schedule
is not sensible.
Clearing Your Plate: Sometimes
we start to eat when we’re hungry and don’t stop when we’re full.
Instead we keep eating until we finish the food that’s in front of us
or until we are uncomfortably stuffed. The best way to avoid this type
of mindless eating is to serve yourself smaller portion sizes.
The Missing Ingredient in Weight Loss
There
are three essential requirements for successful weight loss: calorie
reduction, exercise, and healthy satiety. The slight reduction in daily
calorie intake that is needed for weight loss can be achieved on a
variety of diets: low-fat diet, low-glycemic, Mediterranean, and so
forth. Exercise promotes weight loss by enhancing your daily caloric
deficit, or the gap between the number of calories you consume and the
number of calories your body uses each day.
Healthy
satiety facilitates weight loss by allowing you to maintain a daily
calorie deficit and still feel satisfied. The average weight-loss diet
lasts less than three weeks. One of the major causes of diet failure is
the nagging hunger that comes with eating less. The healthy satiety
strategy is specifically designed to allow you to eat less without
hunger, so you can stay on your diet—any diet—until you reach your goal
weight.
