Bros Do Science - Weekly Must Read - 23/04/2017

Bring your coffee we'll get the rest

Hot news of the week!

AARR is out! Check Alan Aragon’s new research review is out! And as the Brofessor Alan posted: “YEEEEEAAH!!!!!! AARR is UP!!!! Once again, I'm confident I matched the previous issue in terms of sheer quality, and I'm pretty sure I surpassed it in quantity... Awesome guest spots by Matt Kal-El Woodard (the body is smarter than we are), Jacob Schepis (evidence-based personal training: possible or unicorn territory?), and Anthony Howard-Crow gives us a 90-day update on his diet consisting solely of ice cream, protein powder, and a smidge of alcohol. I also discuss breaking research on post-exercise carbs, overfeeding & metabolic flexibility, and I critically analyze a review about added sugars & obesity. I also answer a subscriber's provocative questions about macronutrient composition of caloric surpluses for "lean massing." I'm really stoked about this issue, oh man, wait till you crack it open. :) Don't know what I'm mumbling about: Index of topics & studies covered thus far (don't skip your workout to read this please): Subbers log-in link:

Posts of the week!

Is Sugar Addictive? If ‘TV nutritionists’ and the Daily Mail is anything to go by, it certainly appears that way. Along with news headlines are made up MRIs of rats brains after being fed either sugar or cocaine as justification for the addictive properties of sugar.
Though sugar does have an impact on the reward centres in the brain (food, in general, does that), any rational person would have a hard time putting sugar in the same category as cocaine or heroin.
Fortunately, Westwater and colleagues published a review paper in the European Journal of Nutrition last year that sheds some light on this topic called ‘Sugar addiction: the state of the science’.
The authors summarise the state of the science as follows, “Most of the evidence is limited to the animal neuroscience literature, and it is far from convincing. Importantly, several key elements of drug addiction have not been evaluated in sugar addiction models, such as the transition to compulsive drug-taking and dose-dependent effects on addiction liability. There remains a paucity of human evidence in this area, and we did not consider the literature encompassing the behavioural and neural effects of sweet or palatable food consumption as this would be far too indirect to the question of sugar addiction. There is the problem of the dearth of data on pure sugar consumption as we rarely consume sugar in isolation, and the ecological validity of studies examining pure sugar consumption in humans would be limited…. The science of sugar addiction at present is not compelling. Nevertheless, sugar addiction remains a very popular and powerful idea, but as this special issue illustrates, it is by no means alone in this regard when it comes to misconceptions about sugar. Even the most perfunctory Internet search reveals how much emotive and explanatory power the term ‘sugar addiction’ has when used in its lay sense for individuals personally, as well as in the context of major public debates such as those over the sugar tax or campaigns such as Action on Sugar in the UK. Although the concept as we discuss it here is far more rigorous, the lay interpretation raises the question of whether sugar addiction is a useful (if not valid) concept to help tackle obesity and/or change the food environment? From a policy perspective, it is unlikely that sugar could be excluded from individuals’ diets given its presence in numerous food items, and any analogies suggested based on the regulation of illicit drugs would be specious. Given the multitude of interacting factors that increase one’s risk for eating disorders and obesity, we argue that support of sugar addiction as a primary causal mechanism of weight gain represents an extremely narrow view that fails to capture the complexity of these conditions, and one that may hamper more coordinated and appropriate responses. Furthermore, while there is a pressing need to address these important concerns, we argue that it is dangerous to draw strong conclusions about the validity of sugar addiction based on the current evidence. There are many strong arguments for cutting down the consumption of sugar and reformulating food products accordingly, yet these arguments will all stand or fall according to the scientific case that supports them.”
In short, there’s no evidence that sugar is addictive in humans. That’s not to say that people don’t have a hard time moderating their consumption of highly palatable foods. FREE full-text link:

Rocco Venizelos - Bros Do Science
Rocco Venizelos

My name is Rocco Venizelos and I am currently working in the field of Health and Fitness as a coach, health and fitness advisor and personal trainer. I am also studying at The Anglo-European College of Chiropractic.

My experience the past 15 years in the fitness industry both as an athlete and as Personal Trainer helped me recognize the need to understand in depth the science underpinning all aspects of human performance, to strive for evidence based and theoretical well grounded practices, to validate the importance of keeping yourself up to date of the latest developments and findings in the field. But the most important is to be able to make the science accessible and transferable to coaches, athletes and practitioners.

One of my major concerns is translating knowledge into working practice. This is what I aim to do through with this website.. with the precious help of my Bros!
