Appetite Hormones 101: Peptide YY

Thursday, January 5th, 2012

In this third and final installment of the series, “Appetite Hormones 101”, we will discuss Peptide YY (PYY). The purpose of this series is to explain the role of hormones on both appetite and body weight goals, as it relates to both weight loss and weight restoration. If you’re a new reader, be sure to check out “Appetite Hormones 101: Leptin” and “Appetite Hormones 101: Ghrelin“.

Peptide YY (PYY)

PYY is a hormone that suppresses appetite. It was discovered to play a role in digestion in 1985. PYY regulates food intake, and is believed to improve leptin sensitivity. The amount of PYY released by our bodies is influenced by the number of calories we ingest; the more calories we ingest, the more PYY is released. The diagram below shows how our PYY levels, ghrelin and leptin levels typically fluctuate before and after meals:

PYY levels are highest in individuals battling anorexia, followed by those individuals that are lean,which explains why both groups have less hunger and also may have more difficulty eating. PYY levels are lowest among obese and morbidly obese individuals. Individuals with bulimia also experience low levels of PYY, which helps to explain why all three groups feel more hunger. Research shows that the obese individual can decrease their PYY levels by 30% by reducing their body weight by 5.4%. PYY levels are not believed to be effected by weight restoration during recovery from anorexia. It is also important to note that high levels of PYY in anorexic individuals is associated with decreased bone mineral density (BMD).

Our mood also effects our PYY levels. Recent studies show that PYY levels are higher in those suffering from major depression. This explains why many people with major depression have a decreased appetite and experience weight loss.

PYY levels can be regulated through both diet and exercise. Diets high in quality protein tend to raise PYY levels highest, followed by diets high in healthy fats. High carbohydrate diets tend to raise PYY levels the least. Aerobic exercise has also been proven to raise PYY levels, whereas strength-training has no effect on PYY levels (although strength-training does lower ghrelin levels).

In conclusion, PYY regulates our appetite. The higher our PYY levels are, the more satiated we will feel. You can ensure your PYY levels are highest by eating a high protein diet and including aerobic exercise in our workout routine.

Book Review – Dark Side of Fat Loss

Tuesday, November 29th, 2011

The Dark Side of Fat Loss (Photo from www.darksideoffatloss.com)

I rarely write book reviews, but Dark Side of Fat Loss is a diamond in the rough for those interested in being proactive about their health and nutrition at a time when so many foods contain hidden neurotoxins, carcinogens, and obesogens. This book is a must for anyone on the road to good health. Whether you are happy with your current weight, trying to lose weight, or trying to restore weight, Dark Side of Fat Loss is a required read.

As stated in Croxton’s biography, after graduating from San Diego State University in 2001 with a Bachelor’s in Kinesiology (emphasis: fitness, nutrition, and health), Croxton began his journey as a certified personal trainer. Despite his extensive education in health, he was met with much failure as clients got heavier and sicker. Client programs consisted of endless cardio and the horrific Food Guide Pyramid. Rather than accept defeat, Croxton took his failures as an opportunity for growth. He has since spent thousands of hours educating himself on the many truths that eluded him throughout his formal education, often joking that he got his Master’s from Amazon.com. He is also a Functional Diagnostic Nutritionist (FDN) and Certified Metabolic Typing Advisor (CMTA).

Croxton has created a book that is full of life-changing information. While in many books, all this information might be overwhelming, Croxton’s writing style not only makes it easy to comprehend but a pleasure to comprehend. The real draw to this book is the holistic approach Croxton suggests for obtaining health. He doesn’t suggest to try to correct health issues solely by diet, but by examining the five pillars of health (diet, hormones, digestion, detoxification and immunity). This may be the book that changes your life in the way it needs to be changed.

He discusses how our hormones affect our health goals. He explains how our hormone system are “Like dominoes, when one hormone falls out of balance, others soon follow”. He provides information on hormones (leptin, insulin, cortisol, NPY and ghrelin) and how the body reacts when we have too much or too little of these hormones. He not only explains this in words, but also with the use of graphics. The graphics in this discussion are especially helpful in the explanation of how our hormones interact with our bodies.

He uses a very common-sense approach to addressing some of the dietary issues that many people have. He introduces the concepts of just eating real food, and becoming healthy and fit by doing what healthy and fit people do. He is very down to earth in his approach to choosing healthy foods. He provides solutions to eating healthy when on a budget. He makes suggestions of what foods to eat and what foods avoid and provides information about why certain foods should be avoided. He even provides a handy reference sheet of all these foods.

Like many in his field, Croxton suggests logging calories daily. But, he also does something that is really rare in this type of book. He stresses the importance of listening to our bodies and logging what our bodies tell us. This is so important to him, that he even created a print-friendly body language log. Once again, Croxton doesn’t leave his readers hanging here, he provides solutions to some of the negative body language that many people experience.

Croxton provides a nearly 100 page real food cookbook of recipes that were submitted from real foodists from all over the world. From healthy breakfasts to healthy desserts, this book has it all. Again, the addition of the cookbook truly show Croxton’s mission to make being healthy attainable for all. He knows that if people stress out about what they are going to eat, it will affect their results. He does everything in his power to make the transition to eating real food an easy one.

The Dark Side of Fat Loss is definitely a must-read for all. This will not be a book that you read once and never pick up again. If you are interested in becoming healthy using a holistic approach, this book will be a great ally in fulfilling this goal.

Appetite Hormones 101: Ghrelin

Thursday, November 10th, 2011

This is the second part of the series, ”Appetite Hormones 101″.  This series is designed to explain the role of hormones on both appetite and body weight goals, whether it’s weight loss or weight restoration. “Appetite Hormones 101” will be made up of three articles that describe the major appetite hormones: leptin, ghrelin, and peptide YY.

Ghrelin

Ghrelin, discovered in1999 by scientists, is known as “the hunger hormone”. Produced in the stomach and pancreas, Ghrelin stimulates the appetite with the purpose of increasing the intake of food and promoting the storage of fat.  So when Ghrelin levels are high, we feel  hungry.  After we eat, Ghrelin levels fall and we feel satisfied.

Leptin and Ghrelin have a “teeter-totter” relationship. When leptin levels rise, ghrelin levels fall. Likewise, when ghrelin levels rise, leptin levels fall.

Ghrelin levels are highest right before eating meals and lowest right after eating meals.

Leptin, acts on regulatory centres in the brain to inhibit food intake and increase energy expenditure, acting as a long-term regulator of body weight. Whereas Ghrelin is a fast-acting hormone that operates as a meal-initiation signal for short-term regulation of energy balance.

There are distinct abnormalities in the production of Ghrelin among obese and eating disordered individuals. Those with anorexia tend to have high levels of ghrelin which often normalize with weight restoration.  Among those with bulimia, Ghrelin does not respond as strongly when food is eaten, which could contribute to binge eating as the individual suffering from Bulimia does not “get full” even if they have overeaten. Obese individuals tend to have low levels of Ghrelin, probably because they are Leptin Resistant, since Leptin and Ghrelin are inversely related. Research also shows that Ghrelin levels are higher after an individual loses weight, which may make it more difficult to maintain weight loss.

There are several easy things we can do to help manage ghrelin levels:

  • Eat a diet high in good quality protein (organic, grass-fed, free range etc. when possible)
  • Get an adequate amount of sleep
  • Practice meditation and relaxation techniques to reduce everyday stress
  • Drink plenty of water, since ghrelin levels are affected by thirst
  • Avoid processed fructose (especially high fructose corn syrup)

Although these things can make irregular ghrelin levels tolerable, the best way to normalize ghrelin levels is to address the root cause head on. In most cases, irregular ghrelin levels can be corrected by committing to living a healthier lifestyle through exercise, healthy dietary choices, weight restoration (for the anorexic individual), or weight loss (for the obese individual).
