Speaking at AHS13

The 2013 Ancestral Health Symposium will be held in Atlanta, GA, August 14-17.  Last year was a great conference, and I look forward to more informative talks and networking.  Tickets go fast, so reserve yours now if you plan to attend!

This year, I'll be speaking on insulin and obesity.  My talk will be titled "Insulin and Obesity: Reconciling Conflicting Evidence".  In this talk, I'll present the evidence for and against the idea that elevated insulin contributes to the development of obesity.  One hypothesis states that elevated insulin contributes to obesity, while the other states that elevated insulin is caused by obesity and does not contribute to it.  Both sides of the debate present evidence that appears compelling, and it often seems like each side is talking past the other rather than trying to incorporate all of the evidence into a larger, more powerful model.

There's a lot evidence that can be brought to bear on this question, but much of it hasn't reached the public yet.  I'll explore a broad swath of evidence from clinical case studies, observational studies, controlled trials, animal research, physiology, and cell biology to test the two competing hypotheses and outline a model that can explain all of the seemingly conflicting data.  Much of this information hasn't appeared on this blog.  My goal is to put together a talk that will be informative to a researcher but also accessible to an informed layperson.

On a separate note, my AHS12 talk "Digestive Health, Inflammation and the Metabolic Syndrome" has not been posted online because the video recording of my talk has mysteriously disappeared.  I think many WHS readers would be interested in the talk, since it covers research on the important and interdependent influence of gut health, inflammation, and psychological stress on the metabolic syndrome (the quintessential modern metabolic disorder).  I'm going to try to find time to make a narrated slideshow so I can post it on YouTube.

Food Variety, Calorie Intake, and Weight Gain

Let's kick off this post with a quote from a 2001 review paper (1):

Increased variety in the food supply may contribute to the development and maintenance of obesity. Thirty-nine studies examining dietary variety, energy intake, and body composition are reviewed. Animal and human studies show that food consumption increases when there is more variety in a meal or diet and that greater dietary variety is associated with increased body weight and fat.

This may seem counterintuitive, since variety in the diet is generally seen as a good thing. In some ways, it is a good thing, however in this post we'll see that it can have a downside.

Book Review: Salt, Sugar, Fat

Michael Moss is a Pulitzer prize-winning journalist who has made a career writing about the US food system. In his latest book, Salt, Sugar, Fat: How the Food Giants Hooked Us, he attempts to explain how the processed food industry has been so successful at increasing its control over US "stomach share". Although the book doesn't focus on the obesity epidemic, the relevance is obvious. Salt, Sugar, Fat is required reading for anyone who wants to understand why obesity is becoming more common in the US and throughout the world.

Glucagon, Dietary Protein, and Low-Carbohydrate Diets

Glucagon is a hormone that plays an important role in blood glucose control. Like insulin, it's secreted by the pancreas, though it's secreted by a different cell population than insulin (alpha vs. beta cells). In some ways, glucagon opposes insulin. However, the role of glucagon in metabolism is frequently misunderstood in diet-health circles.

The liver normally stores glucose in the form of glycogen and releases it into the bloodstream as needed. It can also manufacture glucose from glycerol, lactate, and certain amino acids. Glucagon's main job is to keep blood glucose from dipping too low by making sure the liver releases enough glucose. There are a few situations where this is particularly important:

Many deaths world wide have been recorded by having fried food a lot of times in their daily meals, but the studies told us that the fried chicken as an example of fried food dose not an risk factor alone on our heart health, so the advice to you to maintain food that boiled or baked or steamed, those ways are the best to keep foods healthy and away from risk of heart or digestion problems, and steamed way is a best cooking way to make chicken rolls due to the steam will not affect the integrity of proteins in chicken meat and will not leave trans fats after cooking, but if you follow a diet method you should maintain you daily calories.

A cup of steamed rice is about 242 calories, while a cup of fried rice is about 390 calories and 10 additional grams of fat. Regardless of the recent study's findings, the additional calories and fat grams that fried foods add to your diet can have a negative impact on your health if eaten regularly and in large portions.

Eat just a small amount of deep-fried food, and pair it with healthy foods, such as fruits and vegetables, which are low in calories and will not affect your heart health.
