In Part 2  of This Series You Will  See That Hormones  in Our Blood Tell Us To Eat or To STOP Eating.  Our bodies have been pre-programmed to want to eat, that probably explains why we need many hormones to limit our food intake and only a single hormone, grehlin to tell us to eat more.  Even with all the hormonal help many  people have such great difficulties stopping their eating, thru no fault of their own.


Hormones Tell Us To Eat

Why Am I Always Hungry?
Hormones Make Us Hungry
Foods Make Us Hungry
Signals All Around Makes Us Hungry
Hunger is a normal reaction to the absence of food in our system; it is our body’s way of signaling to us that we need to eat. People who successfully lose weight and keep it off understand what is and what  is not hunger is. Hunger management is the key to  losing and keeping off weight

What tells the lady to eat or not eat that piece of  cake?

  • Hormones such as grehlin from the stomach  tell her brain to eat more.

  • Leptin & adinopectin from the fat cells, and GLP1, PYY,  insulin,  from the gastrointestinal tract tell her to stop eating.

Hormonally, our bodies want us to EAT & EAT:
The fact that only a single hormone Grehlin tells us to eat more and many more are required to limit our food intake tells us a lot: Our bodies are programmed to eat, probably genetically from caveman  days where food was scarce.

Hunger vs. Cravings- What is the difference?
In order to successfully manage hunger we must first learn to recognize the difference between hunger and cravings. The “growling” of our stomach, often accompanied by fatigue, weakness and thoughts of food, is hunger. For most of us, almost any food or even drink will stop or at least lessen  the hunger pains. Some foods are better than others to stop hunger- protein and fat.

Cravings are simply a very powerful, irrational need for specific types of foods which can occur even when we are not hungry. Even right after a big meal we can experience cravings.

Hunger is Determined by Two Different Systems-Internal and External

Internal factors tell us to eat or not eat:- the  numerous hormones made in organs all over the human body including fat cells, the pancreas and the stomach as well as emotional
signals like anxiety, depression, habit tell us to eat or not eat.

Recent research indicates that many obese individuals may not be able to lose weight due to alterations in the balance or function of these critical hormones in the internal system.  Some obese people never feel full because they lack some of these hormones, have too much of them or the appetite center in the brain does not recognize them naturally.

Leptin is the  master hormone that sets the foundation for our eating patterns.  Leptin, a hormone produced by fat cells, which is in overall control of body weight on a long-term basis. Leptin tells our brain the status of our energy stores. Too much fat in our fat cells signals the brain to stop eating, while too little signals the brain that it is time to eat.

Other Hormones control our day-to-day and meal-to-meal eating.  Interestingly, it must be easier for the body to EAT than NOT TO EAT, as evidenced by the numerous hormones needed to limit our eating. Those meal to meal hormones include grehlin, insulin, GLP-1 proteins.

External factors coming from outside our bodies.Visual clues, time of day, smells, signs encourage us to eat.

There is also a very substantial group of overweight individuals that are subject to a constant barrage of external stimuli so great that  they overwhelm their own hormonal control centers. This may explain the inability of these people to lose any weight and the absolute fallacy that willpower plays any role at all.


Many chemicals, produced in organs throughout the body, affect body weight. Working together, these signals control how often we eat and how much we eat.

While the inability to lose weight may be due to hormonal abnormalities, it is clear that not every overweight person has these abnormalities.  Moreover, it is almost impossible for anyone to manipulate these internal factors  short of taking drugs.

The smart dieter focuses  on what we can change easily: avoiding  foods that makes us more hungry and external signals that surround everyone telling everyone  to eat and eat.
