Blog Posts Round Up

It's Monday morning and I really don't have time for an in depth post. Just wanted to share some interesting blog posts from around the web.

Weight of the Evidence: Bill Introduced to Mandate Restaurants Deny the Obese Service

An act to prohibit certain food establishments from serving food to any person who is obese, based on criteria prescribed by the state department of health; to direct the department to prepare written materials that describe and explain the criteria for determining whether a person is obese and to provide those materials to the food establishments; to direct the department to monitor the food establishments for compliance with the provisions of this act; and for related purposes.

Junkfood Science: Brain food for kids: Having enough to eat

Efforts to address childhood obesity by lowering fat and calories in school lunch programs are having unintended consequences. A nutrition audit of school children in Florida found that growing youngsters were being underfed and short on vital calories. Some officials whose lunch programs have been flagged for underfeeding children have suggested that since there are still fat children, they must be eating too much and the nutritional guidelines should instead be changed to even greater reductions in fat and calories.

Feeling fat may be worse for you than actually being fat | Dr Briffa's Blog

One factor that may be driving the somewhat distorted messages about obesity and the ‘need’ to lose weight is commercial in nature: pharmaceutical companies, food companies selling foodstuffs with a weight loss angle, and the fitness industry, for instance, will all do a bit better out of having individuals they have an exaggerated sense of what they might lose by not losing weight. However, if the results of a new study are to be believed, there is some suspicion that just feeling like there’s weight to be lost might be contributing to the our physical and mental disease burden.

Think of it this way: As your proportion of home-cooked meals increases, your number of fast-food visits decreases. And USDA scientists found that men eat 500 calories more on days they consume fast foods compared with days they don’t. What’s more, University of Minnesota researchers determined that consuming more prepared meals (i.e. takeout/curbside service and stuff out of a box) and more meals away from home may have a negative impact on overall health.

Female Fitness and Nutrition Scientist: Protein enhances weight loss

This week, Australian researchers published a long-term weight loss study in healthy adult (49 + or - 9 years) overweight women (BMI initially ~32).

In this study, they followed 79 women for more than a year (64 weeks) to see how protein influences weight loss and compliance to a dietary program.

The Heart Scan Blog: Triglyceride traps

Triglycerides are a potent trigger for coronary plaque growth.

Triglycerides in and of themselves probably do not cause plaque growth. Instead, triglycerides contribute to the formation of abnormal lipoproteins in the blood that, in turn, trigger coronary plaque, like VLDL, intermediate-density lipoprotein (IDL), and small LDL. Excess triglycerides also modify HDL structure and cause you to lose HDL in the urine.

About Calories | HoldTheToast Press

But here's why I posed the question in the first place: We've all been told and told and told that fat has more calories than anything else, right? And that's why we were supposed to eat a low fat diet to lose weight -- because by cutting out the fat we'd automatically reduce calories, tra-la. (For the moment let's ignore the fact that when Americans cut cut their fat intake their calorie intake increased.)

So here's the $60,000 question: If calories are fuel, or energy, and fat has more fuel -- more energy -- than anything else, why aren't obese people the most energetic people in the world?

If you look at most weight-loss diets it's very difficult to simultaneously lose significant amounts of body fat and gain lean body mass at the same time. Why? Because you're breaking down one tissue and building another. That's a rather difficult physiological effect to achieve.

So, we thought, the way to prevent that is to combine low carb with weight training. To prove this, we performed a study combining a low-carbohydrate diet with weight training. The hypothesis was that restricting carbohydrates in combination with resistance training would promote the greatest fat loss while actually building muscle tissue. And that's exactly what we found. In fact, the results exceeded my expectations. We had multiple subjects lose 15-20 pounds of fat while gaining 5-10 pounds of lean body mass.

How the media disses low-carb diets I | Health & Nutrition by Michael R. Eades, M.D.

It should come as no surprise to anyone that the media in general dislike low-carb diets. They use a number of tricks to denigrate carbohydrate-restricted diets at every opportunity. I’m going to start a series of posts showing the different methods used by our friends in the press to downplay the efficacy of the diets that millions of people have found so effective.

Is the Tide Turning on Low Carb? « Low Carb Confidential

Am I delusional to say that it seems that the tide is turning on low carb, and that more and more, mainstream science and the media are beginning to embrace some of the notions that labeled Atkins a dangerous quack only a few years ago?

In psychology there is something known as a ‘confirmation bias’ - the tendency to search for or interpret information in a way that confirms one’s preconceptions. See Wikipedia for a list of cognitive biases and check out which ones you see yourself in - enlightening.
