Researchers in Australia have recently completed a study which could indicate that overweight fathers pass molecular 'fat signals' on to their offspring through their sperm. The preliminary results from the study indicate that female offspring are more likely to have obesity problems and to be more obese than the male offspring.
The work by the Robinson Institute Research Centre for Reproductive Health, at the University of Adelaide, has so far focused on microRNA expression on the sperm of laboratory mice, and is now recruiting humans to the study. The researchers had 2 test groups. One was fed a high fat diet and the other a normal diet.
Researcher Dr. Maria Ohlsson Teague said, " In the group fed the high-fat diet, we discovered that male obesity alters the microRNA profile of sperm, resulting in poor embryo quality as well as obesity in offspring. This is the first evidence that a father's nutrition can affect the epigenome of his sperm, a non-genetic mechanism to inform the next generation of environmental change."
It's not all bad news though, according to the research this problem is not a genetic one, per se, so the father has some control over it. If an overweight male lost the weight, increased his fitness level and ate a nutritionally balanced diet those obesity signals may be less likely to be present in his sperm.
If you are thinking of losing weight, getting fit or even just releasing some stress, contact me for details on how to train.
