(Thanks to FSB Associates for this article. The contents of this book is very thought provoking. I never knew the power of serotonin. I was very impressed with the 70 plus recipes in this book given to help you follow their eating plan. I think a lot of diet/healthy eating books forget how important this is for the reader. The quick meals and foods to have on hand was most helpful. I was also impressed that they included "Road Blocks" and "Road Block Assistance" which is a critical lifesaver when you are trying to change your eating habits. Enjoy the article.) 
Serotonin: What It is and Why It's Important for Weight LossBy Judith J. Wurtman, PhD and Nina T. Frusztajer, MD,

Serotonin is nature's own appetite suppressant. This powerful brain chemical curbs cravings and shuts off appetite. It makes you feel satisfied even if your stomach is not full. The result is eating less and losing weight.
A natural mood regulator, serotonin makes you feel emotionally stable, less anxious, more tranquil and even more focused and energetic.
Serotonin can be made only after sweet or starchy carbohydrates are eaten.
More than 30 years ago, extensive studies at MIT carried out by Richard Wurtman, M.D., showed that tryptophan, the building block of serotonin, could get into the brain only after sweet or starchy carbohydrates were eaten. Although tryptophan is an amino acid and found in all protein, eating protein prevents tryptophan from passing through a barrier from the blood into the brain. The reason is simply numbers: Tryptophan competes for an entry point into the brain with some other amino acids. There are more of those other amino acids in the blood than tryptophan after protein is eaten. So in the competition to get into the brain, tryptophan is at a total disadvantage and very little gets in after a protein meal like turkey or snack like yogurt.
But carbohydrates tip the odds in tryptophan's favor. All carbohydrates (except fruit) are digested to glucose in the intestinal tract. When glucose enters the bloodstream, insulin is released and pushes nutrients such as amino acids into the cells of the heart, liver and other organs. As it does this, tryptophan stays behind in the bloodstream. Now there is more tryptophan in the blood than the competing amino acids. As the blood passes by the barrier into the brain, tryptophan can get in. The tryptophan is immediately converted to serotonin, and the soothing and appetite controlling effects of this brain chemical are soon felt.
Our studies with volunteers found that when people consumed a pre-meal carbohydrate drink that made more serotonin, they became less hungry and were able to control their calorie intake. Volunteers whose drinks contained protein -- so that serotonin was not made -- did not experience any decrease in their appetite.
Most of us have experienced the carbohydrate-serotonin effect on our appetite even though we were not aware of the connection. Have you ever munched on rolls or bread while waiting for the main course to be served in a restaurant? By the time dinner is served, twenty minutes or so after you ate the roll, your appetite has been downsized. "I don't even feel that hungry" is a common response when the plate is put down on the table.
This blunting of appetite is not because you may have eaten 120 calories of roll. It is caused by new serotonin putting a brake on your appetite.
Successful weight loss depends on the power of serotonin to control food intake.
The carbohydrate-serotonin connection has a direct impact on our emotional state, too. Drugs that increase serotonin activity have been used for several decades as a therapy for mood disorders. However, our studies showed that natural changes in serotonin could have a profound impact on daily fluctuations in mood, energy levels and attention. In one of our early studies, we found that our volunteers became slightly depressed, anxious, tired, and irritable around 3 to 5 pm every day. At the same time, they experienced, in the words of one volunteer "a jaw-aching need to eat something sweet or starchy." Several studies later, we were able to state that late afternoon seems to be a universal carbohydrate-craving time, and people who experience this craving use carbohydrates to "self-medicate" themselves. Carbohydrate cravers who consume a sweet or starchy snack are increasing serotonin naturally.
We carried out careful clinical studies to measure the effect of carbohydrates on mood and to make sure that the effect was not just due to taste or the effect of taking a break from work. Volunteers, all carbohydrate cravers, were given a carbohydrate or protein- containing food or drink that had identical tastes. Their moods, concentration and energy were measured before and after they consumed the test beverages. The carbohydrate serotonin-producing beverage improved their moods but the protein-containing beverage had no effect on either their mood or their appetite.
Eating carbohydrates allows serotonin to restore your good mood and increase your emotional energy.
Eating low or fat-free, protein-free carbohydrates in the correct amounts and at specific times potentiates serotonin's ability to increase satiety. You will eat less, feel more satisfied and lose weight.
Here are five tips to get serotonin working for you:
- Eat the carbohydrate on an empty stomach to avoid interference from protein from a previous meal or snack. Wait about 3 hours after a meal containing protein.
- The carbohydrate food such as graham crackers or pretzels should contain between 25-35 grams of carbohydrate. The carbohydrate can be sweet or starchy. High-fiber carbohydrates take a long time to digest and are not recommended for a rapid improvement in mood or decrease in pre-meal appetite. Eat them as part of the daily food plan instead for their nutritional value.
- The protein content of the snack should not exceed 4 grams.
- To avoid eating too many calories and slowing down digestion, avoid snacks containing more than 3 grams of fat.
- Do not continue to eat after you have consumed the correct amount of food. It will take about 20-40 minutes for you to feel the effect. Eating more carbohydrates during the interval is unnecessary and may cause weight gain.

Long term success with a weight program sometimes follows a bumpy, uneven path. Many obstacles can keep you from achieving a more healthy weight.

Then stick them in the freezer (as shown in first picture by my lovely friend) for at least 20 minutes! My friend and I had soo much going on that we left them in the freezer for most of the day. It honestly doesn't make a difference as long as they are frozen.
After the bananas have been frozen for the desired time, grab your blender, peanut butter and some sort of chocolate delectable. We chose chocolate milk mix. It didn't over power the treat.
The amount of peanut butter and chocolate you use is based on your personal preference. The more peanut butter you use, the creamier and thicker it'll be. We used about 1 cup of peanut butter (1/2 cup per person) and then poured 1/4 - 1/2 cup of chocolate mix. The end result is...A delicious treat that is tasty, rich, and pretty healthy! Enjoy!
