|The "Curb the cravings w/ sour and bitter foods"-implication is just one out of three science-based hypothesis on potential practical implications of recent studies.|
I can already tell you that not all of them will eventually work - that's how hypothesis work: You formulate them based on the existing evidence, only to realize that you were completely missing the boat, when you argued that eating sour and bitter foods will help you shut down your junk food cravings... which reminds me: Let's not lose additional time and get right to implication numero uno which is, ...
- Implication 1: If you are always ravenous, eat bitter or sour to stop the cravings -- As with all the tips in this first installment of what could become a regular if you signal me that you like the idea of hypothesizing about potential practical applications of the results of recent studies, you got to be careful about the real world effects of the "sour" and "bitter" taste ligand induced production of the "satiety hormone" cholecystokinin (CCK) researchers from the Nagahama Institute of Bio-Science and Technology in Japan observed in isolated gut cells (Miyata. 2014).

And before I forget to mention it: There are "tastebuds" all over your body. The tongue is just one of them | learn more.
- Implication 2: You don't have to move mountains, but 30 minutes x three times a week is the minimal volume x frequency prescription to see significant health benefits from structured physical activity aka "exercise" -- To come to this conclusion I did not even have to come up with extra hypotheses. Actually Heather J. A. Foulds and colleagues, who have recently reviewed the existing literature to elucidate "the relationship between exercise volume and intensity and health benefits" and the results,... well, the results are actually what the tip already said:
"In healthy active individuals, a physical activity program of at least 30 min in duration for three sessions/per week is associated with consistent improvements in health status." (Foulds. 2014).The scientists also found that upping the intensity from brisk waling to jogging is associated with an additional increase in cardiovascular health benefits. If that's exactly the best thing for your knees is anyone's guess, though.
- Implication 3: If you believe in the power of testosterone and want to perform your best at a meet next week, masturbate today! -- According to researchers from the Department of Life Science, at the Hangzhou Normal College in China, the serum testosterone concentrations of their 28 volunteers changed significantly in response to ejaculation at the end of a period of abstinence. While, the fluctuations of testosterone levels from the 2nd to 5th day of abstinence were minimal, a clear peak of serum testosterone appeared, reaching 145.7% of the baseline ( P < 0.01) on day 7 (Jiang. 2003).
The scientists are careful to point out that "[e]jaculation is the precondition and beginning of the special periodic serum testosterone level variations", though. In other words: Years of abstinence are not going to have a similar effect, as a 7-14 day rhythm would have... what? You willingly pass on maxing out your testosterone levels by cyclic abstinence? Well, I can understand that ;-)
