|Check your nutrition labels, I bet you get 2.25g+ leucine and 30mg of B6 from one of your supps already|
So what are you saying here? Is this study a fraud?
I have no evidence that the study was a fraud and I am certainly not implying this, but you must wonder about the magnitude of the weight loss and fat loss difference between the regular and the NuShape supplemented dieters (-500kcal from baseline energy demands calculated simplistically by 1.3× result of the WHO formula for basal metabolic rate), who ingested 2x 1.125 g leucine and 15 mg pyridoxine per day (whether that's on empty is not disclosed in the paper).
|Figure 1: Changes in insulin (μU/ml), HOMA-IR, waist circumference (cm), body weight (kg), fat weight (kg) after 12 (blue) and 24 weeks (orange), relative change from 12-24 weeks is indicated in % below the bars (Zemel. 2013)|
"reductions of oxidative and inflammatory stress biomarkers, such as plasma malondialdehyde (MDA), 8- isoprostane F-2α, tumor necrosis factor-α, and C-reactive protein, as well as an increase in the anti-inflammatory marker adiponectin" (Zemel. 2013)they observed in a previous trial after 4 weeks, even in the absence of weight loss (Zemel. 2012). This would certainly be beneficial for both the lean and the fat individual, but with already low levels of CRP, MDA and TNF-alpha as you, as a healthy follower of physical culture should have them, these changes will be so small that they are unlikely to have any visible effects on you.
There decreased weight / waist / fat loss within the 2nd two weeks in the supplement group (see figure 1, yellow arrow for the discussion of waist circumference as an example) does actually provide evidence that the effect size will decrease the learner you are... even "worse", but rather hypothetical: The effect could also be diminishing, because the human body get's used to the new steady influx of leucine and B6 and their beneficial effects on the mitochondria, Sirt-1 and AMPK expression (learn more; note: as stated in this older article of mine, it works also without resveratrol)
