For Olson, genetic testing indicated she seemingly has a number of genetic and hormonal components setting her starvation and satiety sensors out of whack. One of many GLP-1 medicine – Ozempic – labored briefly. However it turned out one other – Zepbound – higher recalibrated Olson’s hormone imbalance. It was solely when she began tackling her particular weight problems drivers that Olson started dropping plenty of weight – 65 kilos to this point.
