- In particular, the scientists found that the ablation of the prolactin receptor gene in the mice results in profound increases in the expression of master genes controlling brown adipocyte fate (PRDM16) and mitochondrial function (PGC1α, UCP1), which allow - and this is the actual caveat,, here - for an inrease in thermogenesis.The latter, in turn, allows the rodents to burn off a major part of the fat they would otherwise store and thus keeps them relatively lean despite HFD feeding. Aside from the fact that the hyperphagic rodents on the high fat diet were still fat (there is no debating that!), you may savely assume that the effects will be way less pronounced in human beings, where 9/10 "thermogenic" agents that have been successfully tested in rodents do nothing at all, anyway. Against that background the hunger-promoting effects of the prolactin recetor ablation would suggest that it is almost as likely that a drug that block prolactin completely would make obese individiuals even fatter, since that's usually what happens if you eat more - like the mice in the prolactin (-/-) group did (see figure figure 1), without burning more.
- CLA".. So, until my friends from the supplement industry read this post and come out with yet another SuppVersity science powered product with CLA in olive oil* you simply make sure to have a spoon of the liquid gold from time to time, when you feel that you need to take CLA to burn more fat. Unfortunately, this could not just mean that you can rid yourself of the nasty side-effects as discussed in "CLA Destroys Body Fat! But at Which Costs?", but also that the "body fat destruction" will at least be ameliorated if not totally absent :-(* I had hardly written this post, when I browsed the web and found that a certain newcomer and as of late very succesful "yellowish green" company has already a CLA + Olive Oil + Avocado Oil combination on the market, for them this would mean that they didn't even have to change their formula
- All it takes are 24h of "incubation", but that's nothing else than leaving your meat lying in the marinade in your fridge and thus something you would do anyway, right? That's what I would call a convenient, effective and above all totally natural and healthy way of gettting rid of Samonella and Campylobacter :-)
Antibacterial marinades for your meat! Don't worry this is not yet another dysfunctional functional food that's going to make you sick, but an all-natural mixture of green tea, lemon and turmeric you will have to smear onto your chicken meat if you want to make sure to get rid of the C. jejuni and S. enteritidis it may be contaminated with.
Image 2: It's funny how so many things people (or at least chefs) have been doing forever, here marinating meats, simply make sense, isn't it?
- Tons Flaxseed flour in your diet will increase estrogen, but won't decrease the size of your penis, well at least not visible ;-) That's probably the most straight-forward summary of the results, Ludmila Ferreira Medeiros de França Cardozo and her colleagues present in the latest issue of Food and Chemical Toxicology after analyzing the effect of a flaxseed flour containing diet on the expression of hormone levels and penis morphology of male rats (de Franca. 2012) In view of the fact that flaxseed ain't the best source of omega-3s, anyway, and there appears no other good reason (for men and women!) why you would eat them in large quantities (I am not talking about the occasional tablespoon of flaxseed, here), I would still suggest to stay away from it.
While the rats that were maintained on a diet containing 25g of flaxseed flour per 100g for 250days had significantly elevated estrogen levels in the blood 39.5 vs. 32.5 pg/mL (+22%), the minor drop in testosterone did not reach statistical significance and the reduced diameter of the corpus spongiosum, which helps to maintain the urethea as a viable channel for the ejaculation was obviously no problem for the fertility, either - at least the scientist don't mention anything in this regard; unfortunately, they did not really test it, either, as the poor male Wistar rats that were abused in this experiment were bachelors against their will.

- previous posts about the fat burning fatty acid tetradecylthioacetic acid (TTA) and how it's ability to accumulate in various tissues of your body could potentially become problematic. In the short term however, it's anti-inflammatory effects can come very handy. So handy, in fact, that the a recently published study by Pettersen et al. would suggest that we are soon going to see TTA balloons being inserted into coronary vessel walls, in order to deliver the sulfur-containing fatty acid right to an obstructed vessel that's being operated on, in order to suppress the local expression of inflammatory cytokines, as well as the subsequent macrophage infiltration and the unwanted collagen formation, which would precipitate restenosis (=further clogging) of the very heart vessel that has only just been opened operatively.You may now rightly ask yourself what this has got to do with you? Well, if it works locally, it could work similarly systemically and other studies such as Bjørndal (2012) do confirm just that: 0.4% TTA reduce TNF-α, IL-1β, and IL-6 in an experimental model of colitis and render the rodents guts more of less bullet..., ah, pardon, dextran sulfate sodium (DSS; a chemical used to induce cholitis) proof. The long-term effects of the continous consumption of ~3g of TTA, which would be the human equavalent of those 0.4% TTA in the rodent diets is yet still not fully established (re-read: "TTA & Fish Oil" and "TTA & Fish Oil - Revisited").
Of TV watching, sleep deprivation and alcohol consumption, booze has the most pronounced negative effect on reward saliency and inhibitory control of food intake! That's the conclusion Colin Daniel Chapman, Christian Benedict, Samantha Jane Brooks, and Helgi Birgir Schiöth mkae based on their latest meta-review of pertinent studies from pubmed (N=23). With an impact factor of 1.03 on a scale from -4 to 4, alcohol is by far the worst the greatest effect on food intake and shows the highest correlation with obesity (Chapman. 2012).
Figure 3: Alcohol overrides the inhibitory control over food intake (Chapman. 2012)Compared to booze, both sleep deprivation (50% less) and TV watching (20% less) appear almost harmless. Their contribution in the non-drinking part of the population may yet still not be underestimated, also because the urge to do the latter, i.e. watch TV, when you ought tho sleep, precipitates the former and subsequent derangements in the circadian rhythm (suggested read: "The SuppVersity Circadian Rhythm Series").
- IIFYM was yesterday, ROWFYM is today, but what's going to be tomorrow? If that's all Greek to you, let me first bring you in the loop on the acronyms. While IIFYM designates "If It Fits Your Macros", implies (in the most extreme case) that you give a sh*t about what you eat, as long as you hit your macronutrient ratios for the day ("Carbs? Gimme that pizza!") and is getting increasingly popular among those who are fed up with broccoli and chicken breast and either unwilling or unable to see that those are not the only, and I would say, by far not the most healthy foods you can eat, ROWFYM is my own invention, means "Regardless Of Whether It Fits Your Macros" and would probably end up for way too many trainees in a protocol similar to the one 12 of the 24 subjects in a recent study from the Linköping University in Sweden were following for 12 weeks (Hambre. 2012).As you would expect, subjects in both groups managed to gain some weight. The first surprise is that subjects in both groups gained identical amounts of weight, namely 3.6kg. That's not all, however. Even the lean mass increases 2.1kg did not differ between the groups (measure by DEXA scans) and the sophisticated (compared to a similar calories in vs. calories out calculation) measurement of the resting metabolic rate, the scientists had conducted yielded that both groups had compensated for the overeating by a statistically highly significant (p < 0.0001!) + 10% increase in resting metabolic rate!
