SuppVersity - Nutrition and Exercise Science for Everyone

Editorial provides compelling evidence from meta-analyses, but their results are context-dependent ... "The story of fructose reflects the cyclic nature of much in nutrition." That's what John Sievenpiper writes in his latest editorial in  The American Journal of Clinical Nutrition ; and he's right. If you review the history of the science on fructose you will see that it went full circle - not once, but repeatedly. As Sievenpiper points out, the latest meta-analyses by Evans et al. (2017a,b) found (a) beneficial effects on blood glucose especially in people with already messed up glucose management, when sucrose (=sugar) was replaced with fructose, and (b) lowered fasting blood glucose and HbA1c, and triglycerides, plus body weight.

Unless your breakfast looks like this, the study does not mean that you can no longer have breakfast. If you're following the SuppVersity  news, you may remember a post from Wednesday in which I outlined that it is no wonder people fail to lose the weight they intend to, because they try to achieve this weight loss by having soup or, you guessed it, finally doing what the mainstream nutrition experts' cookie-cutter approaches suggest and.. have breakfast, every day . What actually happens to those who fall for the epidemiological bullsh*t science that's trying to extrapolate causal relationships from observational (often unreliable) data has now been demonstrated by a group of US scientists. Believe it or not, Gabrielle Marie LeCheminant et al. are the first researchers to actually experimentally investigated how starting to have breakfast voluntarily will affect your energy intake and weight trajectory.

Beware: Splenda(R) is not sucralose, but 95% dextrose (D-glucose) and + maltodextrin combined with an undisclosed small amount of mostly indigestible sucralose. "These findings further reinforce the idea that 'sugar-free' varieties of processed food and drink may not be as inert as we anticipated. Artificial sweeteners can actually change how animals perceive the sweetness of their food, with a discrepancy between sweetness and energy levels prompting an increase in caloric consumption," Professor Herzog said according to the press release the University of Sydney published last week alongside the publication of a study that was co-authored by Herzog in CELL Metabolism - a study with the telling title "Sucralose Promotes Food Intake through NPY and a Neuronal Fasting Response" (Wang. 2016).

That's rather the low protein variety of overfeeding... but wait, was the high protein diet even "high" in protein? Well high enough to affect liver fat, for sure. You will probably remember José Antonio's high protein overfeeding study series ( learn more ) from the articles here and on the SuppVersity  Facebook page . The results were quite impressive, but the number of controlled covariates were small and the dietary control was limited to food logs. In a more recent study, George A. Bray and colleagues from the Pennington Biomedical Research Center of the Louisiana State University System , the  George Mason University , and the FL Hospital & Sanford-Burnham Prebys Discovery Research Institute  (Bray. 2016) determined the effect of overfeeding diets with 5%, 15% or 25% energy from protein on glycemia + body fat distribution in healthy men and women with add. covariates and  in a metabolic ward. Yes, the high protein intake clogged the liver during o...

Bulking!? What is it that will keep the veins popping, the waist circumference level and your muscle growing? It is your basal metabolic rate? Your body fat level? Your muscle mass? Your fiber type composition? Or maybe your cardio-respiratory fitness? If you have listened to the latest installment of the Science Round Up you will know that there is very practical reason why you want to avoid "classic dirty bulking", with an increased formation of body fat: the accompanying changes to the structure of your adipose organ - the increase in adipopocyte number and thus the touted reason for the future weight problems ( listen to the show to learn more). But let's phase it a certain degree of "overfeeding" is actually necessary to make gains, so the question, which factors there are to predict the changes in body composition and body energy in response to chronic overfeeding is a question that's of equal importance for the lean physical culturist as it is f...
