From: GysdeJongh on 23 Jul 2008 02:22 Diabetes. 2008 Jul;57(7):1768-73. Neurophysiological pathways to obesity: below awareness and beyond individual control. A global obesity epidemic is occurring simultaneously with ongoing increases in the availability and salience of food in the environment. Obesity is increasing across all socioeconomic groups and educational levels and occurs even among individuals with the highest levels of education and expertise in nutrition and related fields. Given these circumstances, it is plausible that excessive food consumption occurs in ways that defy personal insight or are below individual awareness. The current food environment stimulates automatic reflexive responses that enhance the desire to eat and increase caloric intake, making it exceedingly difficult for individuals to resist, especially because they may not be aware of these influences. This article identifies 10 neurophysiological pathways that can lead people to make food choices subconsciously or, in some cases, automatically. These pathways include reflexive and uncontrollable neurohormonal responses to food images, cues, and smells; mirror neurons that cause people to imitate the eating behavior of others without awareness; and limited cognitive capacity to make informed decisions about food. Given that people have limited ability to shape the food environment individually and no ability to control automatic responses to food-related cues that are unconsciously perceived, it is incumbent upon society as a whole to regulate the food environment, including the number and types of food-related cues, portion sizes, food availability, and food advertising. PMID: 18586908 It is often assumed that people make decisions about food and eating in rational conscious ways. However, if this were so, the obesity epidemic would not be happening. People overconsume in response to environmental cues and they lack insight into the extent to which their food choices and eating behaviors are being manipulated by sophisticated advertising and marketing techniques. They also have a limited capacity to sort through the increasingly overwhelming mountains of information and claims about food choices and, as a result, too often choose default option foods high in fat and sugar that, when consumed routinely, lead to chronic diseases. Society needs to act as a whole to reshape the environment to improve the quality and quantity of food we obtain, since the present environment makes it too difficult for most people to do by themselves. Regulations addressing food cues, food availability, portion sizes, and advertising are needed. hth Gys

High carb, particularly HFCS, would be my suspects. But even here, where HFCS isn't so much of a problem, most low fat foods are stuffed with fast-carb fillers. Losing the high fat fear factor would be useful. >Society >needs to act as a whole to reshape the environment to improve the quality >and quantity of food we obtain, since the present environment makes it too >difficult for most people to do by themselves.

Dumping the food pyramid would be a good step, IMO. Nicky. T2 dx 05/04 + underactive thyroid D&E, 100ug thyroxine Last A1c 5.4% BMI 25

Strange how all these phsyiological dietary problems suddenly mushroomed around the time of onset of the Healthy High Carb Low Fat Diet, whatever the form of the (usually fast) carbs. >>Society >>needs to act as a whole to reshape the environment to improve the quality >>and quantity of food we obtain, since the present environment makes it too >>difficult for most people to do by themselves.
