The Almighty EWAG and Some Big Old Belly Fat: How Strength Training Justifies Being Overweight

I was just reading a review of Mark Young's new "How to Read Fitness Research" product. A few questions occurred to me. One, what in the heck is fitness research? There are so many different types of studies and different types of subjects, all of which could fall under the "fitness" umbrella. Many of these have their own specific pitfalls and unique challenges. A person would need to have a more thorough background in the sub-disciplines before simply "learning how to read a study".

Food Compensation: Do Exercise Ads Change Food Intake?

Past research has shown that promotional messages such as food advertising influence food consumption. However, what has gone largely unexplored is the effect of exercise advertising on food intake. This study experimentally tested the effects of exposure to exercise commercials on food intake at a lunch meal as compared to the effects of control commercials.

Get over the Time Magazine Article, Seriously

This is an old post of my reaction to the infamous 2009 Time Magazine Article, "Why Exercise Won't Make You Thin". Even though this has been blogged on by so many others and it is old news I wanted to re-post with a little rewrite because 1) my reaction was quite different than the reaction of the "fitness industry" at large, 2) I think the general reaction says more about the fitness industry than it does about fat loss and 3) it is a good example of the type of disordered priorities that is prevalent in the fat loss world.

Physical Activity Plays an Important Role in Body Weight Regulation

Emerging literature highlights the need to incorporate physical activity into every strategy intended to prevent weight gain as well as to maintain weight loss over time. Furthermore, physical activity should be part of any plan to lose weight. The stimulus of exercise provides valuable metabolic adaptations that improve energy and macronutrient balance regulation. A tight coupling between energy intake and energy expenditure has been documented at high levels of physical exercise, suggesting that exercise may improve appetite control. The regular practice of physical activity has also been reported to reduce the risk of stress-induced weight gain. A more personalized approach is recommended when planning exercise programs in a clinical weight loss setting in order to limit the compensatory changes associated to exercise-induced weight loss. With modern environment promoting overeating and sedentary behavior, there is an urgent need for a concerted action including legislative measures to promote healthy active living in order to curb the current epidemic of chronic diseases.

Evidence for Resistance Training as an Obesity Treatment

Over the last decade, investigators have paid increasing attention to the effects of resistance training (RT) on several metabolic syndrome variables. Evidence suggests that skeletal muscle is responsible for up to 40% of individuals' total body weight and may be influential in modifying metabolic risk factors via muscle mass development. Due to the metabolic consequences of reduced muscle mass, it is understood that normal aging and/or decreased physical activity may lead to a higher prevalence of metabolic disorders. The purpose of this review is to (1) evaluate the potential clinical effectiveness and biological mechanisms of RT in the treatment of obesity and (2) provide up-to-date evidence relating to the impact of RT in reducing major cardiovascular disease risk factors (including dyslipidaemia and type 2 diabetes). A further aim of this paper is to provide clinicians with recommendations for facilitating the use of RT as therapy in obesity and obesity-related metabolic disorders.

Pathways Linking Chronic Sleep Restriction to Obesity

A growing number of studies have identified chronic sleep restriction as a potential risk factor for obesity. This could have important implications for how obesity is prevented and managed, but current understanding of the processes linking chronic sleep restriction to obesity is incomplete. In this paper, we examined some of the pathways that could underlie the relationship between chronic sleep restriction and obesity. This involved exploring some of the potential environmental, health, behavioral, and sociodemographic determinants of chronic sleep restriction, which require further investigation in this context. Three pathways that could potentially link chronic sleep restriction to obesity were then examined: (1) altered neuroendocrine and metabolic function, (2) impaired glucose regulation, and (3) waking behavior. The selected pathways linking chronic sleep restriction to obesity reviewed in this paper are presented in a schematic representation; this may be used to guide future research in this area. This area of research is important because it may lead to more effective interventions and strategies to combat the present obesity epidemic.

Fitness: All Encompassing Means Paralyzing?

In my previous post I presented the talk by Dr. Barry Schwartz regarding “The Paradox of Choice”. Also, I've lately been speaking about having specific goals in our training and making specific choices about the direction our training should take.

If you read my piece on the concept of fitness you’ll see that I don’t think much of the word. Yes, I use it on occasion for brevity or convenience but depending on your perspective it’s either to vague or too all-encompassing.

Portion Size: Effect on Food Intake and Possible Interventions

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.

Self Control: Not all its Cracked Up To Be

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?"

Hunger is a Physical Feeling

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.
