Your inability to shun a second serving may be in your DNA. Roughly one in six people who carry what is sometimes called the “obesity gene”, a variation that boosts risk by around 70%, have more of the hormone ghrelin, which keeps the brain’s “I’m full” light from switching on. Ghrelin has been linked to inducing appetite and feeding behaviors. Circulating ghrelin levels are the highest right before a meal and the lowest right after a meal. Until scientists create some sort of drug to help suppress ghrelin (they’re on it) the best advice is to hit the gym or walking path to help keep the hormone in check and reduce the impact this chromosome blip has on your weight. Ask your PWLC counselor about having a PathwayFit Genetic test done for your own personal report to help you better understand your metabolism and behavior traits.
