Sugars are a ubiquitous component of our food supply. They are consumed as a naturally occurring component of our diet and as additions to foods during processing, preparation, or at the table. A healthy diet contains at least some amount of naturally occurring sugars, because monosaccharides, such as glucose and fructose, and disaccharides, such as sucrose and lactose, are integral components of fruit, vegetables, dairy products, and many grains . Sugars also add desirable sensory effects and promote enjoyment of foods. Over the years, however, sugar intake has been claimed to be associated with several diet-related chronic diseases: diabetes, CVD, obesity, dental caries, and hyperactivity in children [2,3]. One of overwhelming concerns regarding sugars is the potential for excess energy intake from sugars resulting in weight gain and displacement of more nutrient-dense foods . However, little attention has been given to the contribution of sugar and carbohydrates to total energy intake.
Effect of Point-of-Purchase Calorie Labeling on Restaurant and Cafeteria Food Choices: A Literature Review
Eating away from home has increased in prevalence among US adults and now comprises about 50% of food expenditures. Calorie labeling on chain restaurant menus is one specific policy that has been proposed to help consumers make better food choices at restaurants. The present review evaluates the available empirical literature on the effects of calorie information on food choices in restaurant and cafeteria settings.
The prevalence of overweight and obesity has increased. A strong environmental factor contributing to the obesity epidemic is food portion size. This review of studies into the effects of portion size on energy intake shows that increased food portion sizes lead to increased energy intake levels. Important mechanisms explaining why larger portions are attractive and lead to higher intake levels are value for money and portion distortion. This review also shows that few intervention studies aiming to reverse the negative influence of portion size have been conducted thus far, and the ones that have been conducted show mixed effects. More intervention studies targeted at portion size are urgently needed. Opportunities for further interventions are identified and a framework for portion size interventions is proposed. Opportunities for intervention include those targeted at the individual as well as those targeted at the physical, economic, political and socio-cultural environment.

More and more, everyone is learning that "diets" don't work. Sure, people drop weight on diets but they fail to make a lasting change. I don't need to go into this, you know all about yo-yo dieting. Despite this there are still plenty of judgmental folks (who probably wouldn't know a problem if it bit them in the tuchus) who will say stuff like, "jeez, what ever happened to old fashioned self-control?"

While environmental and situational cues influence food intake, it is not always clear how they do so. We examine whether participants consume more when an eating occasion is associated with meal cues than with snack cues. We expect their perception of the type of eating occasion to mediate the amount of food they eat. In addition, we expect the effect of those cues on food intake to be strongest among those who are hungry.

In my post, Instinctual Eating, Thin People, and Appetite, I discussed eating from the perspective of one life-long thin person.
My problem is not, therefore, keeping off fat but eating enough to maintain my strength and of course to continually get stronger. For a person like me that is not so easy to do and involves what seems like a lot of eating. Back when I was still suffering from the bodybuilding affliction it was even worse.

Once in a post about Micheal Pollan's ideas about "nutritionism" and instinctual eating I made the following statement:
“…nutritionists would never tell you that simply eating by your “instincts” is a magical ticket to health.”

I just came across a "nutrition quiz".
I got eight out of ten correct. Only eight? ME? You have got to be kidding me? I am a nutrition stud. Well, perhaps not exactly a nutrition stud but let's just say I do not get my nutrition information from steroid salesmen on bodybuilding forums.
One of the questions on the quiz involved brown rice. Go figure. I knew they wanted to hear that brown rice was healthier than white rice so that is what I answered but really I refuse to capitulate to the nonsense about brown rice being magical health pellets and white rice being evil little starch monsters.

The age old question. And it seems to spark absolute outrage on all sides. Which is "better" for fatloss? Diet alone, exercise alone, or a combination of diet and exercise intervention?
Most people involved with helping the very overweight or obese lose weight will tell you that if you have to choose one then diet alone is the way to go.

Public perception, even that of some health professionals, is that people who are classified as obese are lazy and have made few serious attempts to lose weight . We are now starting to understand that the underlying causes of the obesity epidemic operate at numerous levels – individual, cultural, societal, and biological. We also acknowledge that fad diets are not the solution to weight loss , and that we need to consider a number of short and long term strategies to facilitate the social change needed to enable individuals, families and communities to live healthy lifestyles .
