Corona weight loss

Well, since 2015, I've been struggling with weight loss. At one point around 2017, I weighed 142 kg. With the old calorie counting was not working anymore, I went to an expert (dietitian) who gave me a diet with which I even began gaining weight. The story is very long and interesting, but I began the keto diet (with the guidance of Dr.Bergs YouTube videos and other contributors). I reached 89 kg (as my current weight) I lost a substantial amount during the Corona lockdowns. A friend told me, "everyone I know gained weight but you lost! That's not normal!"
